Answer:
A = 153.86 ft²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
= 3.14 × 7² = 3.14 × 49 = 153.86 ft²
To find out the total temperature change we do some simple addition: The temperature was originally 30c, which dropped to -27c past 0c, so 30+27=57c gives the total temperature change. This occurred over 3 hours, so we divide the total change in temperature by 3 hours: 57/3=19.
So each hour for 3 hours the temperature dropped 19c until it reached -27c.
Answer:
(n + 2)² = 12
Step-by-step explanation:
F(x) = 4 - 2x Domain = x = -4, 0, 5
f(x) = 4 - 2(-4) = 4 - (-8) = 12
f(x) = 4 - 2(0) = 4 - 0 = 4
f(x) = 4 - 2(5) = 4 - 10 = -6
f(x) = 12, 4, -6
The range is C.
60 because every x number equals 60 y numbers also if you divide the last x number which is 4 by the last y number that is 240 you get 60
