Answer:
153.86.
Step-by-step explanation:
Formula for area of a circle: A= Pi R (R is radius) squared. First fill in the numbers: 3.14x7^2 Then Solve for the squared: 7^2=49, then finally multiply 49x3.14 which gets you to 153.86.
The sum means addition.
Add the like terms together.
4x^3+2x^2-4x+3
+ 7x^3-4x^2+7x+8
4x^3 + 7x^3 = 11x^3
2x^2 + -4x^2 = -2x^2
-4x +7x = 3x
3 +8 = 11
The answer is : 11x^3 - 2x^2 + 3x + 11
Area = 36 = length*width
Then, while the area is constant the product length*width is constant.
Length and area are inversely related.
That means that to keep the same product (area), length vary in inverse proportion to width.
If you increase length, widht has to decrease to satisfy this relation:
width = 36/length
Of course, you can also say: length = 36 / width.
Answer:
A fraction is in simplest form if the top and bottom have no common factors other than 1. In other words, you cannot divide the top and bottom any further and have them still be whole numbers.
Answer:
x=2
Step-by-step explanation:
F(x) = 2x^2 - 8x +8
Axis of symmetry lies at the x coordinate of vertex
To find x coordinate of vertex use formula
from the given f(x) , a= 2 and b = -8
Plug in all the values
x=2
So the axis of symmetry at x=2
