Answer:

D. 30 kilometers

Step-by-step explanation:

Add all the given distances relative to the map together:

6.5 + 9.5 + 4 = 20

Multiply that by the scale to convert centimeters to kilometers:

20 x 1.5 = <u>30</u>

Your answer is 30 kilometers.

You also could have gotten the same answer by multiplying each number by the scale and then adding those together but that is slightly more work so the way I showed is more convenient.

Which property can you use to show that 3x + (2x + 4) is equivalent to (3x + 2x) + 4?

Inessa [10]

Step-by-step explanation:

3x + (2x + 4) is equivalent to (3x + 2x) + 4

because there is no change of signs taking place as there is no (-) sign in front of the brackets

3x + (2x + 4) | (3x + 2x) + 4

3x + 2x + 4 | 3x + 2x +4

5x + 4 | 5x + 4

An object is launched straight into the air. The projectile motion of the object can be modeled using h(t) = 96t – 16t2, where t

ratelena [41]

Answer with Step-by-step explanation:

We are given that height of projectile after t seconds is given by

$h(t)=96t-16t^2$

a.h(t)=144 ft

$144=96t-16t^2$

$16t^2-96t+144=0$

$t^2-6t+9=0$

$t^2-3t-3t+9=0$

$t(t-3)-3(t-3)=0$

$(t-3)(t-3)=0$

t-3=0

t=3

After 3 s, the height of the project will be 144 feet in the air.

b.h(t)=0

$96t-16t^2=0$

$16t(6-t)=0$

$16t=0\implies t=0$

$6-t=0\implies t=6$

At t=0, the initial position of projectile

At t=6 s , the projectile will hit the ground.
