D · 24 = -12<br> What does d equal?
Darya [45]

Answer: d=-1/2

<u>Move all terms to the left</u>

<u></u>d*24-(-12)=0<u></u>

<u></u>

<u>Add all the numbers together, and all the variables</u>

<u></u>d*24+12=0<u></u>

<u></u>

<u>Multiply elements</u>

<u></u>24d+12=0<u></u>

<u></u>

<u>Move all terms containing d to the left, all other terms to the right</u>

<u></u>24d=-12\\-12/24\\d=-1/2<u></u>

The height of a stuntperson jumping off a building that is 20 m high is modeled by the equation h = 20 -57, where t is the time
cupoosta [38]

A stuntman jumping off a 20-m-high building is modeled by the equation h = 20 – 5t2, where t is the time in seconds. A high-speed camera is ready to film him between 15 m and 10 m above the ground. For which interval of time should the camera film him?

Answer:

1\leq t\geq \sqrt{2}

Step-by-step explanation:

Given:

A stuntman jumping off a 20-m-high building is modeled by the equation

h =20-5t^{2}-----------(1)

A high-speed camera is ready to making film between 15 m and 10 m above the ground

when the stuntman is 15m above the ground.

height h = 15m  

Put height value in equation 1

15 =20-5t^{2}

5t^{2} =20-15

5t^{2} =5

t^{2} =1

t =\pm1

We know that the time is always positive, therefore t=1

when the stuntman is 10m above the ground.

height h = 10m  

Put height value in equation 1

10 =20-5t^{2}

5t^{2} =20-10

5t^{2} =10

t^{2} =\frac{10}{5}

t^{2} =2

t=\pm\sqrt{2}

t=\sqrt{2}

Therefore ,time interval of camera film him is 1\leq t\geq \sqrt{2}
