An observer 2.5 miles from the launch pad of a space shuttle measures the angle of elevation to the base of the shuttle to be 25
kotegsom [21]

Answer:

Height of shuttle at that instant  = 1.17 miles

Step-by-step explanation:

Refer the given figure.

C is the position of rocket and B is the position of observer.

Here we need to find AC, that is the height of shuttle at that instant.

Using trigonometric rules on ΔABC, we have

      tan25=\frac{AC}{AB} \\\\tan25=\frac{AC}{2.5}\\\\AC=2.5\times tan25\\\\AC=1.17miles

Height of shuttle at that instant = AC = 1.17 miles

Will give point to first correct answer!!
neonofarm [45]

Answer:

f(x) = 3(0.2)^x

Step-by-step explanation:

The leading coefficient is 3 as  x = 0 gives f(x) = 3.

When x = 1, f(x) = 0.6. so try :

0.6 =3(1.2)^1 = 3.6 so it's not the fiirst choice.

0.6 = 3(0.2)^1 = 0.6 so its last choice.

Check when x = -1:

3(0.2)^-1

= 3/ 0.2

= 15

A wedding ring is dropped from a tall building, the distance it has fallen in feet is given by 16t^2, where t is the time in sec
natka813 [3]

Answer:

64

Step-by-step explanation:

As given, the diatance at any point after t seconds is given by

s(t)=16t²

At t=2 seconds then

s(2)=16*2²=16*4=64

Since we're not given the units, it may be feet, inches, meters, kilometers, miles etc. Therefore, the diatance is equal to 64 units
