Answer:

x² + 3x - 989 = 0 (where x is the number of miles traveled on Monday)

Step-by-step explanation:

Let x = number of miles traveled on Monday

Let y = number of miles traveled on Tuesday

Let z = number of miles traveled on Wednesday

Given:

⇒ y = 2x - 5

Given:

⇒ z = x² + 40

Given:

⇒ x + y + z = 1024

Substitute  y = 2x - 5  and  z = x² + 40  into x + y + z = 1024:

⇒ x + 2x - 5 + x² + 40 = 1024

⇒ x² + 3x + 35 = 1024

⇒ x² + 3x - 989 = 0 (where x is the number of miles traveled on Monday)

Answer:

m∠QPS = 112

Step-by-step explanation:

Shape PQRS is a cyclic quadrilateral as every vertex of the quadrilateral touches the circumference of the circle.

The opposite angles in a cyclic quadrilateral add up to 180°.

⇒ m∠QPS + m∠QRS = 180°

⇒ m∠QPS + 68° = 180°

⇒ m∠QPS = 180° - 68°

⇒ m∠QPS = 112°

Answer:

[tex](x + 3, y - 7)[/tex]

Step-by-step explanation:

Given

[tex]Function = (x,y)[/tex]

Translation:

[tex]Left = 3\ units[/tex]

[tex]Down = 7\ units[/tex]

Required

Determine the image of the function

Apply the first translation

[tex]Left = 3\ units[/tex]

When function (x,y) is 3 units translated left, we add the units to the x value.

The new function becomes:

[tex](x,y) -> (x + 3, y)[/tex]

Apply the second translation

[tex]Down = 7\ units[/tex]

We subtract 7 units from the y value

[tex](x,y) -> (x + 3, y)[/tex]

becomes:

[tex](x + 3, y) ->(x + 3, y - 7)[/tex]

Hence:

The image of the function is:

[tex](x + 3, y - 7)[/tex]

Answer:

a) [tex]a_n=3n-1[/tex]

b) [tex]a_n=2n+7[/tex]

Step-by-step explanation:

a)  From inspection, we can see that this is an arithmetic sequence as the difference between each term is the same:

14 - 11 = 3

11 - 8 = 3

8 - 5 = 3

5 - 2 = 3

(so the common difference = 3)

General equation of arithmetic sequence:  [tex]a_n=a+(n-1)d[/tex]

(where [tex]a[/tex] is the first term and [tex]d[/tex] is the common difference between terms)

Given:

[tex]\implies a_n=2+(n-1)3[/tex]

[tex]\implies a_n=2+3n-3[/tex]

[tex]\implies a_n=3n-1[/tex]

b)  From inspection, we can see that this is an arithmetic sequence as the difference between each term is the same:

17 - 15 = 2

15 - 13 = 2

13 - 11 = 2

11 - 9 = 2

(so the common difference = 2)

General equation of arithmetic sequence:  [tex]a_n=a+(n-1)d[/tex]

(where [tex]a[/tex] is the first term and [tex]d[/tex] is the common difference between terms)

Given:

[tex]\implies a_n=9+(n-1)2[/tex]

[tex]\implies a_n=9+2n-2[/tex]

[tex]\implies a_n=2n+7[/tex]

Answer:

3 = f

Step-by-step explanation:

3(6 - f) - 4 = 3f - 4

Distribute within Parenthesis

18 - 3f - 4 = 3f - 4

Combine like terms

14 - 3f = 3f - 4

Add 3f on both sides of the equation

14 = 6f - 4

Add 4 on both sides of the equation

18 = 6f

Divide by 6 on both sides of the equaiton to get your answer of

3 = f

Find lengths by reasoning shortcut

Its a rectangle

Perimeter:-

2(JK+JM)=2(5+3)=2(8)=16units

Answer:

Perimeter = distance around a two-dimensional shape

⇒ Perimeter of a rectangle = (2 × width) + (2 × length)

From inspection of the diagram:

⇒ Perimeter of the rectangle = (2 × 3) + (2 × 5)

                                                 = 6 + 10

                                                 = 16 units

Answer

Step-by-step explanation:

This is exponential growth, so we would use the following equation

y=a(b)^x

500(1.005)^15

1. Initial amount is $500, since that's what we started with.

2. Add the following percentage by 100%

100%+0.5%= 1.005

3. We need to find the account balance after 15 months so raise it to the 15th power.

y= 500(1.005)^15

The balance after 15 months will be $538.84.

Answer:

y = 1/3 x + 8.

or in standard form:

x - 3y = -24.

Step-by-step explanation:

To answer this we use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Here we have m = 1/3 and (x1, y1) = (-3, 7), so:

y - 7 = 1/3(x - (-3))

y - 7 = 1/3( x + 3)

y - 7 = 1/3 x + 1

y = 1/3 x + 8 .

This is the slope-intercept form of the equation.

Converting to standard form, we first multiply by 3:-

3y = x + 24

- x + 3y = 24

x - 3y = -24.

Answer:

10 hours

Step-by-step explanation:

The probability  of the students to be randomly selected between 350 and 550 will be 0.2395 or 24%

we know that the formula for probability is given by

[tex]Z=\dfrac{X-\mu }{\sigma}[/tex]

where,

Z = Z score,

X = raw score,

μ = mean,

σ = standard deviation,

The probability  of the students to be selected randomly between 350 and 550 will be given as

[tex]=P(350 < X < 550)[/tex]

[tex]=P(350-500 < X-500 < 550-500)[/tex]

[tex]=P(\dfrac{350-500}{110} < \dfrac{X-500}{110} < \dfrac{550-500}{110}[/tex]

[tex]=P(-1.36 < Z < 0.45)[/tex]

[tex]=P(Z-1.36)-P(Z-0.45)[/tex]

[tex]=(0.9131-0.6736)[/tex]

[tex]=0.2395[/tex]

Thus the probability of the students to be randomly selected between 350 and 550 will be 0.2395 or 24%

Answer:

30

Step-by-step explanation:

15 x 4 = 60, which means that Beetle has 15 bottles of water and that Ameezy has bottles.  45 - 15 = 30.

Hope this helps :)

Answer:

36 bottles.

Step-by-step explanation:

If you wrote them out, like 1 over 4, 2 over 8, and added up their totals at the bottom, you would eventually reach 60. The last column has 12 over 48, so we subtract 12 from 48, which gives us 36. So the answer is 36 bottles.

Answer:

170 yards

Step-by-step explanation:

First off we know that Rebecca ran 60 yards at first. Then she ran another distance of 80 yards. She then ran diagonally across to get back. If she ran diagonally back that means would have run 30 yards back which is half of the first distance she ran.
(representation of how she ran)

1st: Up along the width |

2nd: sideways along the length ----

3rd: diagonally back to the starting point /

This would form a triangle. The first distance he ran would be halved to show the amount that Rebecca ran diagonally, we will represent this with x.

Equation representation:
60 + 80 = 140 yards

x = 60 divided by 2
x = 30 yards

60 + 80 + 30 = 170 yards

A car is from the previous model year, there is a 10% chance that it is a coupe. Then the correct option is A.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A car dealer organizes the inventory of a specific model of a car into a frequency table comparing the type of car and the model year.

The dealer used the data from the frequency table to create this conditional relative frequency table by column.
