Answer:

Step-by-step explanation:
We begin with the equation
for which we need to solve for a.
The first thing that we can do is to factor out the a from both terms on the left side of the equation

Then we can divide each side by
to isolate a

Let's go ahead and find the difference in height in meters.
1.7-1.5= 0.2 meters
There are 100 centimeters in a meter.
0.2*100= 20
The correct answer is "C". 20 cm.
I hope this helps!

Answer:
5.13 feet
Step-by-step explanation:
Engine is driving the propeller with a radius of 8 feet and its centerline 13 feet above the ground.
And the speed is 700 revolutions per minute, the height of one propeller tip as a function of time is given by:

We have been asked to find the value of height, 'h', when t=4 minutes.
Plugging the value of time, 't', in the equation, we already know that we need to use degrees (not radians) we get:






So the height of one propeller tip at t=4 minutes is 5.13 feet.
So this is how I would do it
4(6)+5
20+5
25
But I could be wrong.
