Answer:

v^2 + 4v - 32

Step-by-step explanation:

( v - 4 ) ( v + 8 )

= v ( v + 8 ) - 4 ( v + 8 )

= v^2 + 8v - 4v - 32

= v^2 + 4v - 32

Find the distance between the given points: (2, -2) and (-4, 7)
sasho [114]

Answer:

3\sqrt{13}

Step-by-step explanation:

Hi there!

We want to find the distance between the points (2, -2) and (-4, 7).

To do that, we can use the distance formula.

The distance formula is given as \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, where (x_1, y_1) and (x_2, y_2) are points

We have everything needed to find the distance, but let's label the values of the points to avoid any confusion

x_1=2\\y_1=-2\\x_2=-4\\y_2=7

Now substitute those values into the formula and solve

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\sqrt{(-4-2)^2+(7--2)^2}

Simplify

\sqrt{(-4-2)^2+(7+2)^2}

\sqrt{(-6)^2+(9)^2}

Square the numbers under the radical

\sqrt{36+81}

Add the numbers under the radical together

\sqrt{117}

Simplify the square root

3\sqrt{13}

Hope this helps!

The graph of y=f(x) is shown below. Find the value of f (0)
meriva

Answer:

f(0) = 2

Step-by-step explanation:

Read from the graph the value "y" that the line presents when "x" is zero. That is the f(0) you are looking for.

See attached screen capture with the point highlighted

f(0) according to the image provided is equal to 2.

f(0) = 2
