X= 3
y = 4
$6.50×3=$19.50
$3.50×4=$14.00
$19.50+$14.00=$33.50

What equation can be written for this graph? <br> Pls help!!!

Answer:

y = 25x

Step-by-step explanation:

This is a straight line, so the formula is:

y = ax + b

a is the slope and b is the y-intercept.

Slope formula:

a = (y2 - y1)/(x2 - x1)

Select two random points from the line:

  1. Point 1: x=2 and y=50
  2. Point 2: x=4 and y=100

Slope a = (100 - 50)/(4 - 2) = 50/2 = 25

=> y = 25x + b

Use one of the points to find b:

50 = 25*2 + b

=> b= 0

So the equation is y=25x

Use a change of variables to find the indefinite integral xe^(x^2) dx
ValentinkaMS [17]
\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12\int2xe^{x^2}\,\mathrm dx

If we take y=x^2, then \mathrm dy=2x\,\mathrm dx, and we can write the above integral as


\displaystyle\frac12\int e^y\,\mathrm dy=\frac12e^y+C

and undoing the substitution, we end up with

\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12e^{x^2}+C

Answer:

Step-by-step explanation:

Cos θ =<u> u*v     </u>

             IuI *IvI

u * v = 7*(-1) + (-2)*2

       = -7 - 4

      = -11

IuI = \sqrt{7^{2}+(-2)^{2}}\\

    = \sqrt{49+4}\\\\

    = \sqrt{53}

I vI = \sqrt{(-1)^{2}+2^{2}}\\

     = \sqrt{1+4}\\\\

      = \sqrt{5}\\

Cos θ = \frac{-11}{\sqrt{53}*\sqrt{5} } \\\\

          = \frac{-11}{16.28}\\\\

   Cos θ = -0.68

θ = 132.5°
