Answer:

The length of the wall would be  12 cm

Step-by-step explanation:

step 1

we know that

On a blueprint with a scale of 1 cm = 4 ft, the length of the wall is 9 cm

so

The actual length of the wall is equal to ------> 9*4=36 ft

step 2

If the scale of the blueprint were 1 cm = 3 ft

then

The length of the wall in the new blueprint would be  ----> 36/3=12 cm

Explain how trigonometry can be used to determine the height of a cell phone tower.
saul85 [17]
Trigonometry can be used to determine the height of a cell phone tower by using SOH CAH TOA or the Pythagorean theorem. If you look at it as a right triangle you can figure out how tall the tower is. If an angle is given (not a 90°angle) and the value of a side you can figure out all of the sides on the theoretical right triangle. Including the height of the tower.

Question part points submissions used as a science project, you drop a watermelon off the top of the empire state building, 320
Nataly [62]
We are given a watermelon dropped at free fall from a building 320 meters above the sidewalk. Superman is headed down at 30 meters per second. We are asked to determine how fast is the watermelon going when it passes Superman. To solve for the final velocity of the watermelon, we will use one of the kinematic equations (free fall):

vf = vi + a*t

where vf is the final velocity
            vi is the initial velocity, zero
            a is the acceleration, in this case, gravitational acceleration = 9.8m/s^2
            t is time

we also need to set-up another equation using the distance:

d = vf + vi / 2 * t

(1) 320 m = vf * t /2

(2) vf = 9.8 m/s^2 * t

From here, we have two equations and two unknown, thus we can solve the problem by substitution.
