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
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
Answer : A {-8}
-4 = b/2
-4 *2 = b
-8 = b
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
