Answer:

B/second option

Step-by-step explanation:

The first option is wrong because you make 30 meatballs in 30 mins but then 30 meatballs in 20 mins. If it was constant then in 20 mins you make less meatballs.

The last option is wrong because if bacteria triples, then that is exponential, not constant change.

Only the middle option makes sense. The rate of change is $35 for each hour!

please give thanks by clicking the heart button! :)

The example that has a constant rate of change is

An electrician earns $50 for the first hour plus $35 for every additional hour.

Option B is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 5 is an equation.

We have,

30 minutes = 30 meatballs

20 minutes = 30 meatballs

This is not a constant rate of change.

$35 for every additional hour.

This means,

1 hour = $35

This is a constant rate of change,

Bacteria triples every hour.

This is an exponential function.

Example:

Number of bacteria initially = 2

Number of bacteria after 1 hour = 3 x 2 = 6

Number of bacteria after 2 hours = 3 x 6 = 18

This is not a constant rate of change.

Thus,

An electrician earns $50 for the first hour plus $35 for every additional hour is a constant rate of change.

Answer:

m = -1/2

Step-by-step explanation:

parallel lines always have the same slope

Answer:

(3/2, 7/2)

Step-by-step explanation:

Given the system of equations;

y = 3x/2 + 5/4..... 1

-2x + 8y = 25 .... 2

Substitute equation 1 into 2;

From 2;

-2x + 8y = 25

-2x + 8(3x/2 + 5/4) = 25

-2x + 12x + 10 = 25

10x = 25 - 10

10x = 15

x = 15/10

x = 3/2

Substitute x = 3/2 into equation 1

From 1;

y = 3x/2 + 5/4

y = 3/2(3/2) + 5/4

y = 9/4 + 5/4

y = 14/4

y = 7/2

Hence the solution to the equation is (x, y) = (3/2, 7/2)

Answer:

The answer is "138.10"

Step-by-step explanation:

Let r also be cone base radius and h = the cone height.  

The radius for the original circle was on either side of the cone plied together = 7.  

The hypotenuse is 7, as well as a right triangle, is formed. So:

[tex]\to h^2+r^2 = 49\\\\ \to r^2 = 49-h^2[/tex]

Calculating the volume of the cone:

[tex]V = (\frac{1}{3}) \pi r^2 h \\\\[/tex]

   [tex]= (\frac{1}{3}) \pi (49 -h^2) h\\\\= (\frac{1}{3}) \pi 49h -h^3\\\\[/tex]

[tex]V'(h) = (\frac{1}{3}) \pi 49 - 3h^2\\\\[/tex]

Setting the derivative to zero and solving for h^2:

[tex]49-3h^2 = 0 \\\\ h^2 = \frac{49}{3} \\\\ r^2 = 49-\frac{49}{3} \\[/tex]

    [tex]= \frac{ 147 -49}{3} \\\\= \frac{98}{3} \\\\[/tex]

Calculating the maximum volume:

[tex]= \frac{1}{3} \pi \frac{98}{3} \frac{7\sqrt{3}}{3} \\\\= \frac{1}{3} \times 3.14 \times 32.66 \times 4.04 \\\\= \frac{1}{3} \times 3.14 \times 32.66 \times 4.04 \\\\= 138.10[/tex]

Answer:

11.362 sq km

1136.2 hectares

Step-by-step explanation:

Given that:

The farm is in the shape of a rectangle.

Dimensions of the rectangular shaped land = 2.6 km by 4.37 km

To find:

Area of land bought in square km and in hectares.

Solution:

First of all, let us have a look at the formula for area of a rectangular shape figure.

[tex]Area = Length \times Width[/tex]

Here,

Length = 2.6 km

Width = 4.37 km

So, Area = [tex]2.6 \times 4.37 = 11.362\ sq\ km[/tex]

To convert square kilometers to hectares, we can use the following conversion formula:

1 sq km = 100 hectares

11.362 km = 100 [tex]\times[/tex] 11.362 = 1136.2 hectares

Answer:

x ≈ 27.2

Step-by-step explanation:

Using the sine ratio in the right triangle

sin54° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{22}{x}[/tex] ( multiply both sides by x )

x × sin54° = 22 ( divide both sides by sin54° )

x = [tex]\frac{22}{sin54}[/tex] ≈ 27.2 ( to the nearest tenth )

Answer:

25

Step-by-step explanation:

because 75 - 50 = 25

The Clare account balance after the deposit of $75 will be $25.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

As per the given,

The account balance initial = -$50

The amount of deposition = $75

Total amount = -$50 + $75

⇒ $25

Hence"The Clare account balance after the deposit of $75 will be $25".

Answer:

Two possible dimensions of the rectangle are 4x and 7/2 y.

Step-by-step explanation:

The Perimeter of a Rectangle

It's given the perimeter of a rectangle is

P = 8x + 7y

The formula to calculate the perimeter of a rectangle of dimensions L and W is:

P = 2W + 2L

Equating term by term, we can guess two possible dimensions of the rectangle:

2W = 8x

Dividing by 2:

W = 4x

And also:

2L = 7y

Dividing by 2:

L = 7/2 y

Thus, two possible dimensions of the rectangle are 4x and 7/2 y.

Answer:

(2, 0)

Step-by-step explanation:

First we need to get the equation of the line passing through the points (3, 1) and (–5, –7)

Equation of a line is y = mx+c

m is the slope

m = y2-y1/x2-x1

m = -7-1/-5-3

m = -8/-8

m = 1

Substitute m = 1 and the point (3, 1) into the equation y = mx+c and get c;

1 = 1(3) + c

1 = 3 + c

c = 1-3

c = -2

The required equation is y = x - 2

We are to look for the coordinate point (x,y) for which both lines intersects, then both equations will be equal as shown;

0.5x - 1 = x - 2

0.5x - x = -2+1

-0.5x = -1

x = -1/-0.5

x = 2

Substitute x = 2 into y = x - 2

y = 2-2

y = 0

Hence the the coordinate point is (2, 0)

If is an isosceles triangle, ​with base AC, AB = 3x+2, BC = 7x-6, and AC = 10x – 10, find the value of x and the length of each side of the triangle.

The sum of angles in a triangle = 180°

AB + BC + AC = 180°

3x + 2 + 7x - 6 + 10x - 10 = 180°

20x -14 = 180°

20x = 180° + 14

Answer:

(-f+v) = -13i-15j

Step-by-step explanation:

Given that,

Vector f = (10,5) = 10i+5j

Vector v = (-3,-10) = -3i-10j

We need to find (-f+v).

Let x = (-f+v)

Plug all the values,

x = [-(10i+5j) + -3i-10j]

= (-10i-3i)+(-5j-10j)

= -13i-15j

Hence, (-f+v) = -13i-15j
