Answer:

its true

You have to put your f (5) in the equation x + 1 because your x is greater than 3, and putting it in the lower equation is wrong, and when you put it in your lower equation, you put your x, which is 5, +1, and the answer is 6.

So that's true~

jenyasd209 [6]

Answer:

146.66 hours.

Step-by-step explanation:

Given: Height of snow at the beginning is 84 inches.

           Snow melting rate is 0.15 inches per hour.

           

Now, finding number of hours to reach 62 inches of snow.

First lets find the number of inches reduced.

Reduced inches of snow= 84\ inches - 62\ inches= 22\ inches.

∴ Reduced inches of snow is 22 inches after melting at 0.15 inches per hour.

Next finding hours to melt 22 inches of snow.

Time= \frac{total\ size}{melting\ rate}

⇒ Time= \frac{22}{0.15} = 146.66\ hours

Hence, 146.66 hours would it take for the snow to reach 62 inches.

The measure of central angle ABC is radians.
mezya [45]

Answer:

9\pi\ units^{2}

Step-by-step explanation:

we know that

The measure of central angle ABC is \frac{\pi}{2} radians

so

\frac{\pi}{2}=90\°

360\° subtends the complete circle

The area of the shaded sector is the area of a quarter circle

so

The area of a quarter circle is equal to

A=\frac{1}{4}\pi r^{2}

we have

r=6\ units

substitute

A=\frac{1}{4}\pi (6)^{2}=9\pi\ units^{2}
