Answer:

-20

Step-by-step explanation:

Do the math in the parenthesis first

A feasible region has vertices at (-1,3), (3,5), (4,-1), and (-1,-2) find the maximum and minimum values of each function

Molodets [167]

Answer: Choice D.
Max: f (-1,-2)=4; min:f(3,5)=-11

----------------------------------------
----------------------------------------

Work Shown:

Plug in (x,y) = (-1,3)
f(x,y) = -2x-y
f(-1,3) = -2*(-1)-3
f(-1,3) = 2-3
f(-1,3) = -1
------------------
Plug in (x,y) = (3,5)
f(x,y) = -2x-y
f(3,5) = -2*3-5
f(3,5) = -6-5
f(3,5) = -11
------------------
Plug in (x,y) = (4,-1)
f(x,y) = -2x-y
f(4,-1) = -2*4-(-1)
f(4,-1) = -8+1
f(4,-1) = -7
------------------
Plug in (x,y) = (-1,-2)
f(x,y) = -2x-y
f(-1,-2) = -2*(-1)-(-2)
f(-1,-2) = 2+2
f(-1,-2) = 4
------------------
The four outputs are: -1, -11, -7, and 4

The largest output is 4 and that happens when (x,y) = (-1,-2)
So the max is f(x,y) = 4

The smallest output is -11 and that happens when (x,y) = (3,5)
So the min is f(x,y) = -11

This all points to choice D being the answer.

Answer:

$m$

Step-by-step explanation:

we know that

In a quadrilateral inscribed in a circle opposite angles are supplementary so

$m$

Step 1

Find the value of x

substitute the values

$x^{2} +3x=180\\ \\ x^{2} +3x-180=0$

using a graphing tool

solve the quadratic equation

see the attached figure

$x=12\°$

step 2

Find the measure of angle D

$m$

substitute

$74\°+m$

$m$

Table tennis the path of a table-tennis ball after being hit and hitting the surface of the table can be modeled by the function

grin007 [14]

Check the picture below.

the ball hits the table, when it hits "the ground" or goes all the way back down, at that point, the height of the ball is 0, thus h = 0.

$\bf 0=-4.9t(t-0.42)\implies t=
\begin{cases}
0=-4.9t\\
0=t\\
------\\
0=t-0.42\\
\boxed{0.42=t}
\end{cases}$
