So to do this one, you have to do the problem backwards!

The equation looks like this with everything plugged in:

272.2 = 2(3.14)r

You are looking for r, so start dividing

272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r

Therefore the radius is about 43.3 in.

I hope I helped!

For a quadratic function, which characteristics of its graph is equivalent to the zero of the function? a) y-intercept b) maximu

Sonja [21]

Answer:

d) x-intercept

Step-by-step explanation:

The zeros of a function are the values of x that make y = 0.

Thus, they are the points where the graph crosses the x-axis, that is, the x-intercepts.

a) is wrong. the y-intercept is simply the value of y when x = 0.

b) and c) are wrong. A quadratic can have only one maximum or one minimum; it can't have both. And they are not zeros except in the special case of y = ±ax².

The diagram below is the graph of y = x² + 3x - 46. It shows the zeros at x = -23 and x = 20. The minimum and the y-intercept are not zeros of the function.

Express 192 as a prime factors in order

iVinArrow [24]

You can write this two ways - as a list of prime factors, or combine like factors and represent their quantity with an exponent.
If you begin by dividing by two, you can do that six times, with a three as the remaining prime factor.
2·2·2·2·2·2·3
OR
2∧6 · 3

What is the value of g(−3) when g(x)=2x−2 ?

nikdorinn [45]

For these types of problems, plug the value inside the ( ) into the (x) of the equation.
g (-3), g (x) = 2x-2
g (x) = 2 (-3) - 2 = -6 - 2 = -8
g (-3) = -8
