Let's find the area of the outer circle and the inside circle
the inside's circle area
A= π x 6²=36<span>π
the outer's
A' = </span>π x 4x²= 4<span>πx²
A'-A=4</span>πx²- 36π=160πcm² equivalent to x²- 9=40, so x²=49 implies x =sqrt(49)=7, x=7<span>

Give an example of how the zero product property applies to solving quadratic equations
mestny [16]

Answer:

How the zero product property applies to solving quadratic equations?

The zero product property states that if the product of two quantities is zero, then one or both of the quantities must be zero. ... When you factor, you turn a quadratic expression into a product. If you have a quadratic expression equal to zero, you can factor it and then use the zero product property to solve.

The number in parenthesis after f is the x coordinate. Basically, it says which y coordinate is tied with an x value. In choice a, it says that when x is 0 y is 3, etc.

So, you can look at the graph to see which answer choice has a point from the graph. Choice a says (0,3), and that does not match. Choice b says (5,-1) and that does match. So the answer is B.

*(x,y)*

The ratio of boys to girls in a group is 4:1. If there are 33 more boys than girls, work out how many people there are in total.
MissTica

Total number of people is 55

<u>Step-by-step explanation:</u>

Step 1:

Given ratio between boys and girls is 4:1. Let number of girls be x, so number of boys = 33 + x

⇒ 4x + x = x + 33 + x

⇒ 5x = 33 + 2x

⇒ 3x = 33

⇒ x = 11

Step 2:

Find total number of people.

33 + 2x = 33 + 22 = 55

Cylinders are 3D figures, as they are solids with volume and take up space.

2D figures are flat figures that you can draw, like a square or circle.

1D figures are actually just a line, a segment, or a point, etc.

I have no idea how to graph g(x)..or why f(x) is relevant..... Steps would be helpful!! I got a final twomorrow ;-;​
SSSSS [86.1K]

When you derive a function from another using the transformation

g(x) = f(x+k)

you're translating the graph of the parent function f(x) horizontally.

More specifically, you translate the graph k units to the left if k is positive, k units to the right if k in negative.

So, starting from the graph of f(x), you have that the graph of

g(x) = f(x+3)

is the same graph of f(x), but shifted 3 units to the left.
