Answer:

  • A = 2, B = 1, C = 28

Step-by-step explanation:

Find the slope of the line AB.

<u>The slope:</u>

  • m = (11 - 9)/(11 - 7) = 2/4 = 1/2

Since the altitude is perpendicular to AB, it has a slope of -2.

The line with the slope of -2 and passes through point C(6, 16).

<u>Use point-slope equation to find the line:</u>

  • y - 16 = -2(x - 6)
  • y - 16 = -2x + 12
  • y + 2x = 16 + 12
  • 2x + y = 28

A = 2, B = 1, C = 28

Answer:

Solution given:

A(7,9)

B(11,11)

C(6,16)

Slope of AB=\frac{11-9}{11-7}=\frac{2}{4}=½

since altitude is perpendicular to it .

so its slope becomes negative reciprocal to the slope of base

so

slope of altitude(m) =-2

now

equation of a line passing through C(6,16) perpendicular to its base is:

By using formula

y-y_{1}=m(x-x_{1})

y-16=-2(x-6)

solve it

y-16=-2x+12

y+2x=12+16

in the form of Ax +By=C is:

2x+y=28

:.

<h3 /><h3><u>A=2</u></h3>

<u>B=1</u>

<u>C=28</u>

Answer:

y = x³

Step-by-step explanation:

Note that

1³ = 1 × 1 × 1 = 1 ← value of y- coordinate

2³ = 2 × 2 × 2 = 4 × 2 = 8 ← value of y- coordinate

3³ = 3 × 3 × 3 = 9 × 3 = 27 ← value of y- coordinate

4³ = 4 × 4 × 4 = 16 × 4 = 64 ← value of y- coordinate

5³ = 5 × 5 × 5 = 25 × 5 = 125 ← value of y- coordinate

The rule is that the y- coordinate is the cube of the x- coordinate, that is

y = x³

Find the surface area of the prism 12in 4 in 3in 5in 5in 6in​
Mamont248 [21]

Answer:

Area of trapezoid:

12 + 6<-- your two bases of the trapezoid = 18

18 x 4 = 72, 72 divided by 2 = 36

now we multiply by 2 since there are 2 trapezoids:

36 x 2 = 72

Area of rectangle in front:

6 x 3 = 18

Area of the 2 rectangles on the sides:

5 x 3 = 15

(multiply by 2 since there are two rectangles on both sides)

15 x 2 = 30

Area of rectangle on the back:

12 x 3 = 36

Now lets add up all the areas:

72 + 18 + 30 + 36 = 156 in2 is your answer.

Sarah bought a $320000 house. She pays 20% down and takes out a 30-year loan for the rest. How much is the loan amount going to
lana [24]
The first thing you do is mutitpy 320,000 by .20 so that you can find the amount of down payment. The down payment would be 64,000. So you subtract 64,000 from 320,000. This leaves a loan amount of 256,000 dollars. The answer is 256,000 dollars .
