Consider functions f and g below.
Scrat [10]
Answer: -12 x^2 - 3x + 27  

In this question, there are two function of f(x) and g(x) 
f(x)= -9 x^2 - 7x + 12
g(x)= 3x^2 -4x -15
The question is about f(x)- g(x). To answer this, you just need to replace the question with the function. Don't forget to apply the minus to all the product inside the function. The calculation would be:

f(x)- g(x)= 
(-9 x^2 - 7x + 12) -(3x^2 -4x -15)=
-9 x^2 - 7x + 12 (-3x^2 +4x +15)= 
-12 x^2 - 3x + 27

A cone has a height of 20 centimeters and a volume of 4,710 cubic centimeters. What is the area of the base of the cone?
olchik [2.2K]

Answer:

706.5 cm^2

Step-by-step explanation:

First we need to find the r to find the area of the base which is the circle so we use the volume to find r

V = 1/3πr^2h now adjust the equation for r

r = √3V/πh

r = √3(4710)/20π

r= 15

now that we have r, the base of cone is a circle so we use the area formula for circle

area  = πr²

area = 3.14 (15)^2

area of base = 706.5 cm^2

If the numbers below were ordered from least to greatest, which number could you use to replace the blank? 0.20,2/5 □ , 3/4,8/10
faust18 [17]
1/2 would work for the blank space

because as shown in the image you could relate it to a whole for each one and put it to 100 to figure out what the blank could be

the 0.20 can be converted to 1/5 so that way you can put everything into the 100 group
