Option D is correct.
An equation: h = 28000 -2000m
Step-by-step explanation:
Let h represents the height of the airplane and m represents the minutes.
As per the given statement: An airplane 28,000 feet above ground begins descending at a constant rate of 2,000 feet per minute.
At ground m = 0
h(0) = 28000 feet.
⇒ An airplane descending at a constant rate (r) = - 2000 feet per minute
then,
height(h) of the airplane after m minutes is given by:
h(m) = 28000 - rm ; where r is the rate descending at constant rate and m is the minutes.
Substitute the given values we get;
h(m)= 28000 -2000m
Therefore, an equation which gives the height, h of the airplane after m minutes is; h = 28000 -2000m
Answer:

Step-by-step explanation:
Given a circle centre J
Let the radius of the circle =r
LK is tangent to circle J at point K
From the diagram attached
Theorem: The angle between a tangent and a radius is 90 degrees.
By the theorem above, Triangle JLK forms a right triangle with LJ as the hypotenuse.
Using Pythagoras Theorem:

The length of the radius, 
The correct question is
<span>The radius of a cylinder is 5" and the lateral area is 70pi sq. in. Find the length of the altitude.
</span>
we know that
[surface lateral area]=(2*pi*r)*height
height= [surface lateral area]/(2*pi*r)
surface lateral area=70*pi in²
r=5 in
so
height= [70*pi]/(2*pi*5)------> 7 in
the answer is
7 in
Her friend's house is 1/12 miles away from her house.
Since 1/4 miles is 1/3 of the way, 1/4 x 1/3 = 1/12.
