Step-by-step explanation:

1.Draw a triangle

2. Measure one of the sides of the triangle

3. Place a point at the midpoint of one of the sides of the triangle.

4. Draw a line segment from the midpoint to the opposite vertex. The segment you just created is called a median.

Use f(x) = 2 x and f-'(x) = 2x to solve the problems.
Westkost [7]

Answer:

f(2) = 1

f(1) = \frac{1}{2}

f^{-1}(2)=4

Step-by-step explanation:

Consider the provided functions.

f(x) = \frac{1}{2}x

f^{-1}(x)=2x

Find f(2) as shown.

Substitute x=2 in f(x) = \frac{1}{2}x

f(2) = \frac{1}{2}\times2

f(2) = 1

Find f(1) as shown.

Substitute x=1 in f(x) = \frac{1}{2}x

f(1) = \frac{1}{2}

Find f'(2) as shown.

Substitute x=2 in f^{-1}(x)=2x

f^{-1}(2)=2(2)

f^{-1}(2)=4

The vertex of the graph of y = -4(x + 3)2 + 2 is ( , )
andrezito [222]

Answer:

Step-by-step explanation:

This quadratic is of the form

y=-a(x-h)^2+k where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).

On a spinner P (3)=2/3 and the p (4)=1/8. what is the probability of getting 3 or 4
bagirrra123 [75]
For the probability of one thing or another, you add the two probabilities together. In that case, the probability of getting 3 or 4 is (2/3) + (1/8) = 19/24
