The length of a rectangle is 4 yd more than twice the width x. The area is 390
masya89 [10]

Step-by-step explanation:

step 1. let l be the length of the rectangle

step 2. l = 2x + 4

step 3. lx = 390 yd^2

step 4. (2x + 4)x = 390

step 5. 2x^2 +4x = 390

step 6. 2x^2 + 4x - 390 = 0

step 7. -4 +- sqr(4^2 -4(2)(-390))/2(2) quadratic formula

step 8. (-4 +- sqr(3136))/4

step 9. (-4 +- 56)/4

step 10. x = 13yd, l = 2x + 4 = 2(13) + 4 = 30yd.

mario62 [17]

Answer:

$ 9.86

Step-by-step explanation:

Tax = 6% of 9.30

      = 0.06 * 9.30

     = $ 0.558

Total costs = 9.30 + 0.558

                  = 9.858

                  = $ 9.86

Create a circle with center A and a radius of your choice. Create a point B on the circle, and find the coordinates of B. Draw t
ser-zykov [4K]

<u>Corrected Question</u>

Create a circle with center A and a radius of your choice. Create a point B on the circle, and find the coordinates of B. Draw the radius AB. What is the slope-intercept form (y = mx + b) of the equation of AB? Show your work.

Answer:

y=0.62x+2

Step-by-step explanation:

In the attached circle drawn using Geogebra

  • Center is at point A(0,2)
  • Point B on the circumference has coordinates (1.7,3.05)
  • Radius of the circle=2 Units

Gradient of AB, m=\dfrac{y_2-y_1}{x_2-x_1} where (x_1,y_1)=A(0,2)$ and (x_2,y_2)=B(1.7,3.05)

m=\dfrac{3.05-2}{1.7-0} \\=\dfrac{1.05}{1.7}\\\\\approx 0.62

Line AB intercepts the y-axis at y=2, therefore: b=2

The slope-intercept form of the line AB (in this case) is therefore:

y=0.62x+2

For every circle center A of radius r and point B chosen on the circumference, the equation of the line AB will be different.
