A pre-image includes a line segment with the length of z units in a slope of M units the pre-image is dilated by a scale factor of N. The length of a corresponding line segment in the image is blank units

We have that the area of the infield is 81 in2.

This area is a square, which means it has equal sides, and its area is:

If the area of the square is 81 in2, we have that:

So the side of the infield is 9 inches.

The hang time is calculated to be a. 1.5 seconds if the vertical component of velocity for the projectile is 7.3 meters/second.

The formula for the height of the projectile can be used to calculate the hang time as follows;

h = ut - 0.5at²

here;

h is the height of the projectile

u is the velocity = 7.3 m/s

a is the acceleration due to gravity

The standard value of acceleration due to gravity is equal to 9.81 m/s²

The height will be zero both the times when t=0 and when the journey has been completed

Now adding these values to the formula;

h = ut - 0.5at²

0 = 7.3t - 0.5(9.81)t²

Solving for t;

4.905t² = 7.3t

4.905t² / t = 7.3

4.905t = 7.3

t = 7.3 / 4.905

t = 1.49 ≈ 1.5

Therefore; the hang time is calculated to be 1.5 seconds.

The solution set of the given inequality is:

9.52  ≤  x  ≤ 22.22

Or [9.52, 22.22] if we write this as an interval.

Here we have the inequality:

200 ≤ 15.75x + 50 ≤ 400

Which represents Kali's earning potential.

To solve the inequality we need to isolate the variable in the middle, if we subtract 50 in the 3 sides we get:

200 - 50 ≤ 15.75x + 50  - 50 ≤ 400 - 50

150 ≤ 15.75x ≤ 350

Now we need to divide both all by 15.75, so we get:

150/15.75 ≤ 15.75x/15.75 ≤ 350/15.75

9.52  ≤  x  ≤ 22.22

This is the solution of the inequality, the solution set written as an interval will be [9.52, 22.22]

After using translation the image of the given points will be at Q( 6 , 6 ) and  M( -2 , -11 ).

What is translation ?

The linear movement of a point relative to its initial position is known as translation. The horizontal position is labeled first and the vertical position is labeled second when describing a point's coordinates with respect to the origin of an x-y coordinate plane.

The translation is given to be (x,y) → (x + 1, y - 3)

The tow points are Q(5,9), M(-3,-8)

using translation  we get,

Q( 5 , 9 ) → (5 + 1, 9 - 3) = Q( 6 , 6 )

M( -3 , -8 ) → (-3+ 1, -8- 3) = M( -2 , -11 )

The rate of change of the level of the swimming pool is -0.019 inches per hour.

The rate of change will be given by the quotient between the change in the level of the water (-3/16 inches) and the time in which that change happens.

We know that the change happens between 10 pm and 7:45pm, so the number of hours is:

2 hours + 7 hours + 45 min

Where:

1 hour  = 60 min

45 min = 45/60 hours = 0.75 hour

Then the total time is:

2h + 7h + 0.75h = 9.75h

Then the rate of change is:

Since Sylvia needs to sign up for exactly one class in each subject, so the total number of different combinations from which she has to choose will be

    ⁴C₁ * ²C₁  *  ³C₁  *  ⁵C₁  

= 4!/1!( 4 - 1 )!  × 2!/1! ( 2 - 1 )!  ×  3!/1! ( 3 -1)!  × 5!/1! ( 5 - 1 )!
