1. using 2 dots that are on the blue line (0,72) and (6,69)
find the slope:

slope = change in Y over change in x = 69 - 72 / 6-0 = -3 / 6 = -1/2
 equation would be y = -1/2x + 72

2. y = -1/2x+72 = -1/2(30) +72 = -15 +72 = 57 beats per minute

3. replaced x in the equation with 30 to find the beats per minute for exercising 30 minutes

Jason jumped of a cliff into the ocean . His height as a function off time could be models as h(t)=16tsquared + 16t + 480 where
Karo-lina-s [1.5K]

I see that you are in high school, and I'm hoping that you've been introduced
to differential calculus, because I don't know how to answer this question without
using it.

We're told that Jason's height above the water is  <em>H(t) = -16t² + 16t + 480 .</em>
We can observe many things from this equation:
-- Up is the positive direction; down is the negative direction.
-- The acceleration of gravity is 32 ft/sec² .
-- Jason jumps upward from the cliff, at 16 ft/sec .
-- The cliff is 480-ft above the water.
(This tells us why the question is only concerned with his maximum height,
and then it ends ... 480-ft is one serious cliff, and what happens after the
peak of his arc is too gruesome to contemplate.)

In any case, his vertical velocity is the first derivative, with respect to time,
of his height above the water.

         V = -32 t + 16

At the peak of his arc, where gravity takes over, his velocity changes from
upward to downward, and it's momentarily zero.

                                           0 = -32t + 16

Add  32t  to each side:    32t = 16

Divide each side by  32:    <em>  t = 1/2 second</em>

His height at that instant is     H(0.5) = -16(0.5)² + 16(0.5) + 480 =

                                           <em>4-ft above the cliff,  484-ft above the water</em>,

and then he begins falling from that altitude.

The duration of his dive is      484 = 16 t²
                                                   t = √(484/16) = <em>5.5 seconds</em>

and he hits the water at      V = a t = (32) x (5.5) = 176 ft/sec = <em>exactly 120 mph </em>

Jason was good man ... a good student, and always kind to everyone he met.
He will certainly be missed.

What is the answer to this -7= x/4?
murzikaleks [220]

Answer:

x= -28

Step-by-step explanation:

Multiply both sides as in -7 and 4

x

-7= --- ---> -7 x 4= -28 = x

4

-28 = x. (Swap Sides) X= -28
