Answer: a) 6, 0, 10       b) yellow/orange line  

Step-by-step explanation:

a) Plug the x in the y functions, y = 2x² + x

when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6

when x = 0, y = 2(0)² + (0) = 0 + 0 = 0

when x = 2, y = 2(2)² + (2) = 8 + 2 = 10

b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.

And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.

Write a equation of a line perpendicular to the line below in point-slope from that passes through the point (-2,6)
STatiana [176]

Answer:

Option 1: y-6=-4(x+2)

Step-by-step explanation:

Find the slope of the perpendicular line by finding the negative reciprocal of the original slope. (Negative reciprocal = flip upside down and add a negative). So we get -4 for the perpendicular slope.

Next, we know the point (-2,6) is on the line, so we can get x=-2 and y=6.

Plug this into point-slope form: y_{1}-y_{2}=m(x_{1}=x_{2})

y_{1} - (6)=-4(x_{1}-(-2))

y-6=-4(x+2)

Sketch the vectors u and w with angle θ between them and sketch the resultant.
Rama09 [41]

Given:

Two vectors (u) and (w) and the angle between them θ

\begin{gathered} |u|=50 \\ |w|=12 \\ \theta=35\degree \end{gathered}

the sketch of the vectors will be as shown in the following figure:

As shown, the resultant vector is the blue line segment

The vector R has a magnitude = 60.22

And the angle between u and R = 5.56°

Evaluate the function f(x) =-x/2 -7x -2 find f(-9)
NeX [460]

Answer:

f(-9)=\frac{131}{2}

Step-by-step explanation:

In order to evaluate a function at a given x-value, plug in that value into the actual function

f(x)=-\frac{x}{2} -7x-2\\\\f(-9)=-\frac{9}{2} -7(-9)-2\\\\f(-9) = \frac{131}{2}
