Find the area of the figure​

Mathematics
1 answer:
Sedbober [7]2 years ago
6 0

Check the picture below.

so the figure is really a 6x21 rectangle, a 2x2 square, and a couple of quarter of a circle whose radius is 2, now, if put two quarters together, we get half, so both of those quarter circles add up to just a semi-circle with a radius of 2.

\stackrel{\textit{\huge Areas}}{\stackrel{rectangle}{(6)(21)}~~ + ~~\stackrel{square}{(2)(2)}~~ + ~~\stackrel{two~\frac{1}{4}~circle}{\cfrac{1}{2}\pi (2)^2}}\implies 126+4+2\pi \implies 130+2\pi

An air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute. Select all
Radda [10]

Answer:

The correct options are 3, 4 and 5.

Step-by-step explanation:

It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.

It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).

The ball falls at a rate of 50 ft per minute. So, the rate of change is

m=-50

The height of balloon is defined as

h(x)=-50x+1000                      [\because y=mx+b]

Where, x is time in minutes.

The balloon will reach the ground when h(x)=0

0=-50x+1000

50x=1000

x=20

Therefore the options 3, 4 and 5 are correct.
