Identify the unit rate in each graph. Then, order the graphs by unit rate, from least to greatest.

Answers

Answer 1

The required rates are: Unit rate of graph K = 3, Unit rate of graph P = 0.5, and Unit rate of graph F = 1. The order from lower to greater is Graph P, graph F, graph K

How did we determine their unit rates?

Step 1: As we know that Unit Rate

Step 2: Notice that the in graph K line passes through the point (1,3)

Step 3: (1,3)

It means the value of function is 3 when x= 1

Step 4: So the unit rate of graph K is, 3/1

Step 5: Simplify the expression.

3/1 = 3

Step 6: Similarly we can see that the graph P have the point (2, 1)

Step 7: So the unit rate of graph P will be 1/2

Step 8: Simplify the expression.

1/2 = 0.5

Step 9: The graph F have point (1, 1) so it have unit rate of 1/1

Step 10: Simplify the expression.

1/1 = 1

Step 11: So we have unit rate of graph K = 3, F= 1 and graph P = 0.5

Step 12: Putting them in least to greater order as,

0.5, 1, 3

It follows that;

graph P, graph F, graph K

Therefore, the required answer is,

Unit rate of graph K = 3

Unit rate of graph P = 0.5

Unit rate of graph F = 1

And the order from lower to greater is, Graph P, graph F, graph K

Maxine's credit card has an APR of 27.99%. If her current monthly balance, before interest, is $1,834.50, what will her monthly interest charge be? (4 points) $42.78 $42.79 $51.67 $65.54

Answers

Answer:

  (b)  $42.79

Step-by-step explanation:

You want the monthly interest charge on a balance of $1834.50 when the annual rate is 27.99%.

Monthly rate

The monthly interest rate is the annual rate divided by 12. This means the interest charge is ...

  I = Prt . . . . . interest on P at annual rate r for t years

  I = $1834.50 × 0.2799 × 1/12 ≈ $42.79

Her monthly interest charge will be $42.79.

The graph of a sine function has an amplitude of 4, a midline of y=2, and a period of 10.

There is no phase shift. The graph is reflected over the x-axis.

What is the equation of this function?

Answers

The equation of the given sine function is y = 4 × sin((π/5)x) + 2.

The equation of the given sine function can be determined based on the given information. We know that the general form of a sine function is:

y = A × sin(Bx - C) + D,

where A represents the amplitude, B represents the frequency, C represents the phase shift, and D represents the vertical shift.

In this case, we are given the following information:

Amplitude (A) = 4: The amplitude is the distance between the maximum and minimum values of the function. Since the function is reflected over the x-axis, the amplitude is positive 4.

Midline (D) = 2: The midline is the horizontal line around which the graph oscillates. In this case, it is y = 2, indicating a vertical shift of 2 units upwards.

Period = 10: The period is the distance between two consecutive peaks (or troughs) of the function.

Given that there is no phase shift, the phase shift (C) is 0.

From the given information, we can deduce the values of A, B, C, and D to construct the equation.

A = 4 (amplitude)

D = 2 (vertical shift)

C = 0 (no phase shift)

To determine B, we use the formula:

B = 2π / Period

Plugging in the value for Period (10), we can calculate B:

B = 2π / 10 = π / 5

Therefore, the equation of the given sine function is:

y = 4 × sin((π/5)x) + 2.

The distance between Miami, Florida and Bermuda is about 1042 miles. The distance from Bermuda to San Juan. Puerto Rico is about 965 miles, and the distance from San Juan to Miami is about 1038 miles. Find the area of the triangle formed by the three locations.

Answers

Answer:

444523.45 square miles

Step-by-step explanation:

By using Heron's formula, we can easily find the area of the triangle formed by Miami, Bermuda, and San Juan, we need to use the lengths of the three sides of the triangle.

Let,

Side a: Distance from Miami to Bermuda = 1042 miles

Side b: Distance from Bermuda to San Juan = 965 miles

Side c: Distance from San Juan to Miami = 1038 miles

Now we can use Heron's formula to find the area of the triangle:

s =[tex]\frac{a+b+c}{2}[/tex]

s = [tex]\frac{1042 + 965 + 1038}{2}=1522.5[/tex] miles

A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

A = [tex]\sqrt{1522.5(1522.5-1042)(1522.5-965)(1522.5-1038)}=444523.45[/tex]

Therefore, the area of the triangle formed by Miami, Bermuda, and San Juan is approximately 444523.45 square miles.

Answer:

444,523.45 square miles (2 d.p.)

Step-by-step explanation:

To find the area of a triangle formed by the locations of Miami, Bermuda, and San Juan, use Heron's formula.

[tex]\boxed{\begin{minipage}{8 cm}\underline{Heron's Formula}\\\\$A=\sqrt{s(s-a)(s-b)(s-c)}$\\\\where:\\ \phantom{ww}$\bullet$ $A$ is the area of the triangle. \\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the side lengths of the triangle. \\ \phantom{ww}$\bullet$ $s$ is half the perimeter.\\\end{minipage}}[/tex]

Label the three sides of the triangle as 'a', 'b', and 'c', where 'a' is the distance from Miami to Bermuda (1042 miles), 'b' is the distance from Bermuda to San Juan (965 miles), and 'c' is the distance from San Juan to Miami (1038 miles):

a = 1042 milesb = 965 milesc = 1038 miles

To find the half perimeter, s, half the sum of the three side lengths:

[tex]\implies s=\dfrac{a+b+c}{2}=\dfrac{1042+965+1038}{2}=1522.5[/tex]

Substitute the values of a, b, c and s into Heron's formula and solve for area, A:

[tex]\begin{aligned}A&=\sqrt{s(s-a)(s-b)(s-c)}\\&=\sqrt{1522.5(1522.5-1042)(1522.5-965)(1522.5-1038)}\\&=\sqrt{1522.5(480.5)(557.5)(484.5)}\\&=444523.4468348...\\&=444523.45\; \sf miles^2\;(2\;d.p.)\end{aligned}[/tex]

Therefore, the area of the triangle formed by the three locations is 444,523.45 square miles, to two decimal places.

• [tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

then

[tex]log_{3}[/tex] (3x) + [tex]log_{3}[/tex] 3 = 5

[tex]log_{3}[/tex] (3x) + 1 = 5 ( subtract 1 from both sides )

Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity:


In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC.


The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC.


Which of these could be a step to prove that BC2 = AB2 + AC2?

possible answers -
By the cross product property, AB2 = BC multiplied by BD.
By the cross product property, AC2 = BC multiplied by BD.
By the cross product property, AC2 = BC multiplied by AD.
By the cross product property, AB2 = BC multiplied by AD.

Answers

The correct step to prove that [tex]BC^2 = AB^2 + AC^2[/tex] is:

By the cross product property, [tex]AC^2 = BC \cdot AD[/tex].

To prove that [tex]BC^2 = AB^2 + AC^2[/tex], we can use the triangle similarity and the Pythagorean theorem. Here's a step-by-step explanation:

Given triangle ABC with right angle at A and segment AD perpendicular to segment BC.

By triangle similarity, triangle ABD is similar to triangle ABC. This is because angle A is common, and angle BDA is a right angle (as AD is perpendicular to BC).

Using the proportionality of similar triangles, we can write the following ratio:

[tex]$\frac{AB}{BC} = \frac{AD}{AB}$[/tex]

Cross-multiplying, we get:

[tex]$AB^2 = BC \cdot AD$[/tex]

Similarly, using triangle similarity, triangle ACD is also similar to triangle ABC. This gives us:

[tex]$\frac{AC}{BC} = \frac{AD}{AC}$[/tex]

Cross-multiplying, we have:

[tex]$AC^2 = BC \cdot AD$[/tex]

Now, we can substitute the derived expressions into the original equation:

[tex]$BC^2 = AB^2 + AC^2$\\$BC^2 = (BC \cdot AD) + (BC \cdot AD)$\\$BC^2 = 2 \cdot BC \cdot AD$[/tex]

It was made possible by cross-product property.

Therefore, the correct step to prove that [tex]BC^2 = AB^2 + AC^2[/tex] is:

By the cross product property, [tex]AC^2 = BC \cdot AD[/tex].

We mixed 5l of 45% alcohol, 4l of 82% and 1l of 92% alcohol. How many percent alcohol does the resulting mixture contain? ​ I got 58.6% and im wondering IF that's correct.

Answers

The resulting mixture contains approximately 64.5% alcohol, not 58.6% as you mentioned.

To solve this problem

We can calculate the weighted average of the alcohol percentages based on the volumes of each component.

Let's figure out how much alcohol there is overall in the mixture:

Total alcohol is calculated as follows: (Volume of 45% alcohol) * (Property of 45% alcohol) + (Volume of 82% alcohol) * (Property of 82% alcohol) + (Volume of 92% alcohol) * (Property of 92% alcohol).

Total alcohol = (5 liters) * (45%) + (4 liters) * (82%) + (1 liter) * (92%)

Total alcohol = 2.25 liters + 3.28 liters + 0.92 liters

Total alcohol = 6.45 liters

Let's now determine the amount of alcohol included in the final mixture:

Alcohol content is calculated as (total alcohol / total mixture volume) * 100.

The mixture's total volume is  = 5 liters + 4 liters + 1 liter = 10 liters

Alcohol content: (6.45 liters / 10 liters) x 100 = 64.5%

Therefore, the resulting mixture contains approximately 64.5% alcohol, not 58.6% as you mentioned.

To show that the points (2, 5), (5, 2), and (6, 6) form a triangle, we can calculate the slopes of the lines connecting these points. If the slopes are all distinct, then the points form a triangle.

Let's calculate the slopes:

The slope between (2, 5) and (5, 2):

m₁ = (y₂ - y₁) / (x₂ - x₁)

= (2 - 5) / (5 - 2)

= -3/3

= -1

The slope between (2, 5) and (6, 6):

m₂ = (y₂ - y₁) / (x₂ - x₁)

= (6 - 5) / (6 - 2)

= 1/4

The slope between (5, 2) and (6, 6):

m₃ = (y₂ - y₁) / (x₂ - x₁)

= (6 - 2) / (6 - 5)

= 4/1

= 4

the third term of an arithmetic sequence is 7 and the twelfth term in 106. what is the one hundredth term of the sequence

Answers

Answer:

a₁₀₀ = 1074

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

given a₃ = 7 and a₁₂ = 106 , then

a₁ + 2d = 7 → (1)

a₁ + 11d = 106 → (2)

solve the equations simultaneously to find a₁ and d

subtract (1) from (2) term by term to eliminate a₁

(a₁ - a₁) + (11d - 2d) = 106 - 7

0 + 9d = 99

9d = 99 ( divide both sides by 9 )

d = 11

substitute d = 11 into (1) and solve for a₁

a₁ + 2(11) = 7

a₁ + 22 = 7 ( subtract 22 from both sides )

a₁ = - 15

Then

a₁₀₀ = - 15 + (99 × 11) = - 15 + 1089 = 1074

In Mathematics and Geometry, the surface area (SA) of a cylinder can be calculated by using this mathematical equation (formula):

SA = 2πrh + 2πr²

Where:

h represents the height.r represents the radius.

Note: Radius = diameter/2 = 8/2 = 4 m.

By substituting the side lengths into the formula for the surface area (SA) of a cylinder, we have the following;

Surface area = 2πrh + 2πr²

Surface area = 2(π)(4)(11) + 2(π)(4²)

Surface area = 120π square units.

Part b.

Assuming the diameter and the height of the cylinder are cut in half, we have:

Surface area = 2(π)(4/2)(11/2) + 2(π)((4/2)²)

Surface area = 2(π)(2)(5.5) + 2(π)(2²)

Surface area = (π)(2)(11) + 2(π)(4)

Surface area = 22π + 8π

Surface area = 30π square units.

Scale factor = 30π/120π

Scale factor = 1/4.

When Grace opens and lays a shipping box out flat, she sees that the top and the bottom of the box
both measure 10 inches by 14 Inches, the sides of the box both measure 14 inches by 8 inches, and
the front and back of the box both measure 8 inches by 10 inches. What is the surface area of Grace's
strooing box?

Answers

The surface area of Grace's shipping box is 664 square inches.

We have,

The box can be divided into six rectangles, each of which represents the face of the box.

To find the surface area of the box, we need to find the area of each face and then add them all up.

The top and bottom of the box are both 10 inches by 14 inches, so the area of each of these faces is:

= 10 x 14

= 140 square inches

The sides of the box are both 14 inches by 8 inches, so the area of each of these faces is:

= 14 x 8

= 112 square inches

The front and back of the box are both 8 inches by 10 inches, so the area of each of these faces is:

8 x 10

= 80 square inches

To find the surface area of the whole box, we add up the areas of all six faces:

= 2(140) + 2(112) + 2(80)

= 280 + 224 + 160

= 664 square inches

Therefore,

The surface area of Grace's shipping box is 664 square inches.

candy bars. A box of candy bars (p) costs
$64 and Angel has no more than $230 to
spend on the order. What inequality
represents her situation?
Op 64 >= 230
Op 64 <= 230
O p/64 <= 230
O p/64 >= 230

Answers

Answer:

p/64 <= 230

Step-by-step explanation:

The inequality that represents Angel's situation is:

p/64 <= 230

This inequality states that the number of boxes of candy bars, represented by p, divided by 64 (the cost of each box), is less than or equal to 230 (the maximum amount Angel has to spend on the order).

How many 1/3 inch cubes does it take to fill a box with a width of 2 2/3 inches, length of 3 1/3 inches with a height 2 1/3

Answers

The number of 1/3 inch cubes required to fill the box is 62.

Volume of box

Volume = length × width × height

Height = 7/3

Length = 10/3

width = 8/3

Hence ,

Volume = 7/3 × 10/3 × 8/3 = 560/27

Size of cube = 1/3
