Decide whether the two expressions are equivalent for each problem below.

Q varies inversely as the square of p, and Q = 36 when p = 7. Find Q when p = 6.

antiseptic1488 [7]

Answer:

C.Q=49

Step-by-step explanation:

Q=k

P squared

39=k

7 squared

k=1911

<h3> therefore Q is. </h3>

Q=1911

6 squared

Q=1911

39

Q=49

A ball is thrown upward with an initial velocity of 16 ft/sec from a height of 32 ft above the ground. The height, in feet, of t

GaryK [48]

Answer: 2 seconds.

Step-by-step explanation:

Given : A ball is thrown upward with an initial velocity of 16 ft/sec from a height of 32 ft above the ground.

The height, in feet, of the ball t sec after it is thrown can be represented by

$s=-16t^2+16t+32.$

When ball reaches the ground , s= 0.

$\Rightarrow -16t^2+16t+32=0$

Divide both sides by 16 , we get

$-t^2+t+2=0\\\\\Rightarrow\ t^2-t-2=0\\\\\Rightarrow\ t^2-2t+t-2=0\\\\\Rightarrow\ (t-2)(t+1)=0 \\\\\Rightarrow\ t=2,-1$

But time cannot be negative , so t= 2.

Hence , it will take 2 seconds for the ball to reach the ground.

Answer:

(x, y) ⇒ (x -5, y +3)

Step-by-step explanation:

Pick a point on the original polygon. The extreme left point (at (1, 0)) will do.

Locate the corresponding image point on ABCDE. (It is point B(-4, 3).) Using coordinates, or counting grid squares, determine what must be added to the original point to get the image point.

Here, that addition is 5 squares left and 3 squares up:

image - original = (-4, 3) -(1, 0) = (-5, 0)

So, the transformation rule adds -5 to each x-coordinate and 3 to each y-coordinate:

(x, y) ⇒ (x -5, y +3)
