If the diameter is d = 8, then we divide that in half to get the radius of r = 4.
If the radius is r = 9, then we double it to get the diameter of d = 18
The formulas are:
- radius = diameter/2
- diameter = 2*radius
I'll let you determine the others.
Hey there! :)
Answer:
f(-2) = -148.
Step-by-step explanation:
To calculate f(-2), simplify substitute -2 for x in the equation. Therefore:
f(x) = 4x³ -12x² + 40x + 12
Becomes:
f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12
Simplify:
f(-2) = 4(-8) - 12(4) - 80 + 12
f(-2) = -32 - 48 -80 + 12
Finally, you get:
f(-2) = -148.
Answer: y=(-3x+7)/2
Isolate y.
2y= -3x+7
y= (-3+7)/2
Answer: x=(-2y+7)/3
Isolate x
3x=-2y+7
x=(-2y+7)/3
Answer: 6x+4y=14
Idk if that counts but multiply the whole equation by 2.
We are given the equation:
√10(128 + 2)
We can simplify what is in parenthesis.
√10(130)
We can put the number in parenthesis on the left side of the square root.
130√10
As a decimal, it would equal approximately 411.10
Best of Luck!
Answer:
tell him to add 5 negative x tiles to get all of the x's to one side of the equation. You need to do this because getting all the x's to one side will help you solve the equation because if all of the x's are on one side you can add or divide numbers to the other side and solve for x.
