Answer:
y= -2x +2.5
Step-by-step explanation:
19.625cm squared because you have to divide the diameter by 2 to get the radius.
Area of circle = pi times radius times radius
= 3.14 times 2.5 times 2.5
= 19.625cm squared
Answer:
x=0,![\sqrt[6]{5}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B5%7D)
Decimal form,
x=0,1.30766048......
Step-by-step explanation:
x
=
x-=0
(take x as a common factor)
x(-
)=0
So,
x=0 and -=0
for 
-=0
(add for both sides)
=
x=![\sqrt[3]{\sqrt[2]{5} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Csqrt%5B2%5D%7B5%7D%20%7D)
(multiply 3 by 2)
x=
So,
x=0,
To find it directly
A = 2 pi r h
A is proportional to rh
factor 2
A is multiplied by 2 * 2 = 4
factor 3
3 * 3 =9
factor 5
5 * 5 = 25
factor 10
10 * 10 = 100
(b) the increase in A by factor x is x^2
c(20)^2 = 400
Plug in the given numbers (x) to the equation.
For example, let's take the first value it gives us.
-10(-2) +y=4
20+y=4
y=-16
Then you would put that on the table, and plug in the next value(s).
Hope this helped!
