For problems 1, 2, and 3, use the function g(x) = sin(6x) .
Fantom [35]

Step-by-step explanation:

1. Amplitude = 1.  g(x) = 1 sin(6x).  The coefficient 1 is the amplitude.  The range of the function is -1 \le g(x) \le 1  or, in interval notation, [-1, 1]

2. The period is  \frac{2\pi}{6}=\frac{\pi}{3}.

x-intercepts (at the beginning, middle, and end of the period) 0,\,\frac{\pi}{6},\,\frac{\pi}{3}

Maximum (1/4 of way through period)  \left(\frac{\pi}{12},\,1 \right)

Minimum (3/4 of way through period)  \left( \frac{\pi}{4}, \, -1 \right)

Find the inverse of the function.
Akimi4 [234]

Answer:

Step-by-step explanation:

The inverse is found by interchanging the x and y values and solve the result for y.

I will use y for f(x)

y = 4x^2

Inverse

x = 4y^2              Divide by 4

x/4 = 4y^2 /4    

x/4 = y^2             Take the square root of both sides.

sqrt(x/4) = sqrt(y^2)

y = sqrt(x/4)

g(x) = sqrt(x/4)  If you have a very fussy teacher, the inverse function could be written as

g(x) = +/- sqrt(x)/2

I expect that if the question is computer marked, I would try g(x) = sqrt(x)/2 first.

If the surface area of a sphere is 4534.16cm squared what is the radius of the sphere
scoundrel [369]

Answer:

The surface area of a sphere is calculated by formula:

A = 4 x pi x radius^2

=> radius =  sqrt(A/(4 x pi) = sqrt(4534.16/(4 x pi)) = 19 (cm)

Hope this helps!
