I'm confused, but if you want me to add all the numbers I got negative 8.
Answer:
-4 is the average rate of change from 3 to 4
Step-by-step explanation:
Average rate of change is defined as the fraction of change in f(x) value to change in x value.
Here we have x values as 3 and 4.
To find the average rate of change from x=3 to x=4
Average rate of change = change in f(x)/change in x
f(4) = -5^{4-3} +2 = -3\\f(3) = 1\\f(4)-f(3) = -3-1 =-4
Change in x = 4-3 =1
Answer:
whichever one corresponds with the answers you have will be right.
Answer:
C
Step-by-step explanation:
The cakes which overlap are the small and middle & the middle and large. The total area of overlap for these cakes will be the surface of the smallest layer's base plus the surface of the middle layer's base.
We can find the area by where r is radius which is half the diameter.
Smallest cake - D=7.5, so r=3.75
=10.5625 × π = 33.1830724035 or 33.2
Middle Cake - D=10, so r=5.
=25 × π = 78.5398163397=78.5
We add together 33.2+78.5= 111.7 cm squared
C is the closest.
Answer:
addition property of equality.
Step-by-step explanation:
4(3 x^2 + 2) - 9 = 8 x^2 + 7
We can add 9 to each side, by using the addition property of equality.
a=b then a+c = b+c
