Answer:

The total amount paid by Gabriel at the local gas station is $70.49.

Step-by-step explanation:

Cost of gasoline per gallon = $2.75

Cost of diesel per gallon = $3.02

Amount of gasoline Gabriel needs = 15.2 gallons

Amount of diesel Gabriel needs = 9.5 gallons

Compute the total amount paid by Gabriel at the local gas station as follows:

Total Cost = Cost of gasoline × Amount of gasoline

                           + Cost of diesel × Amount of diesel

                =(2.75\times 15.2)+(3.02\times 9.5)\\\\=41.8+28.69\\\\=70.49

Thus, the total amount paid by Gabriel at the local gas station is $70.49.

Trig: Which complex number's graph is shown?
Andrei [34K]

ANSWER

2 \sqrt{2} ( \cos( \frac{7\pi}{4}   + i  \sin(  \frac{7\pi}{4} ) )

EXPLANATION

The complex number shown has coordinates (2,-2)

or

z = 2 - 2i

The modulus is

|z|  =  \sqrt{ {2}^{2}  +  {( - 2)}^{2} }

|z|  =  \sqrt{ 8} = 2 \sqrt{2}

The argument is

\theta= \tan^{ - 1} ( \frac{ - 2}{2} )

\theta= \tan^{ - 1} ( -1) =  \frac{7\pi}{4}

The polar form is

2 \sqrt{2} ( \cos( \frac{7\pi}{4}   + i  \sin(  \frac{7\pi}{4} ) )

The first option is correct.

Passes through (-8, -7), parallel to the graph of y=1/2x-3
KIM [24]

Answer:

y=\frac12x-3

The answer is the same line as given in the question.

Step-by-step explanation:

Hello!

Slope-intercept Form: y = mx + b

  • y = output
  • m = slope
  • x = input
  • b = y-intercept

Given our Line: y=\frac12x-3

  • slope = \frac12
  • y-intercept =3

Parallel lines have the same slope but a different y-intercept, so the second line should have a slope of \frac12.

To find the y-intercept, we plug in the x and y values from the point into a blank equation with the slope and solve for b.

  • y = \frac12x + b
  • -7 =\frac12 (-8) + b
  • -7 = -4 + b
  • -3 = b

The equation is y=\frac12x-3, hence the same line.
