Answer:
-1
Step-by-step explanation:
A function is represented by the following symbol f(x) where f(x) further represents y like this ,
so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?
We can see in the graph when x = 5 the value of y is -1 to be exact so
f(5) = -1
or
Answer:
2 one that's the right one
All cone-shaped cups have the same height in 8 inches. They just differ in their diameters. To solve for the volume of the regular and jumbo sizes, let's use the formula for the volume of cone
V = (1/3)*pi*(r^2)*h
r is just the half of the diameter, h is the height which is equal to 8
Regular size:
V = (1/3)*pi*((4/2)^2)*8
V = 33.5 cube inches
Jumbo size:
V = (1/3)*pi*((8/2)^2)*8
V = 134.0 cube inches
In order to round to the nearest 100 you look at the 10s place.
It's 7 which means we round up. So 178 rounded to the nearest 100 is 200.<span />
