Answer:

k = 7

Step-by-step explanation:

Applying,

S = (y₂-y₁)/(x₂-x₁)................ Equation 1

Where S = slope of the line.

From the question,

Given: y₂ = 10, y₁ = 4, x₂ = k, x₁ = 1, S = 1

Substitute these values into equation 1

1 = (10-4)/(k-1)

crossmultiplying,

(k-1) = (10-4)

k-1 = 6

k = 6+1

k = 7

The area of a square in square feet is
Sedaia [141]

Answer:

Part 1) The expression for the perimeter is P=4(25z-3) or  P=100z-12

Part 2) The perimeter when  z = 15 ft. is P=1,488\ ft

Step-by-step explanation:

Part 1)

we have

625z^{2}-150z+9

Find the roots of the quadratic equation

Equate the equation to zero

625z^{2}-150z+9=0

Complete the square

Group terms that contain the same variable, and move the constant to the opposite side of the equation

625z^{2}-150z=-9

Factor the leading coefficient  

625(z^{2}-(150/625)z)=-9

625(z^{2}-(6/25)z)=-9

Complete the square. Remember to balance the equation by adding the same constants to each side

625(z^{2}-(6/25)z+(36/2,500))=-9+(36/4)

625(z^{2}-(6/25)z+(36/2,500))=0

Rewrite as perfect squares

625(z-6/50)^{2}=0

z=6/50=0.12 -----> root with multiplicity 2

so

The area is equal to  

A=625(z-0.12)(z-0.12)=[25(z-0.12)][25(z-0.12)]=(25z-3)^{2}

The length side of the square is b=(25z-3)

therefore

The perimeter is equal to

P=4b

P=4(25z-3)

P=100z-12

Part 2) Find the perimeter when  z = 15 ft.

we have

P=100z-12

substitute the value of z

P=100(15)-12=1,488\ ft

George places $5,000 into an account that earns a simple interest of 4.3%. John places $5,500 into an account that earns 4%. Who
olchik [2.2K]

Answer/Step-by-step explanation:

<u><em>George: </em></u>

4.3% ÷ 100 = 0.043

0.043 × 5000 = 215

<em><u>John:</u></em>

4% ÷ 100 = 0.04

0.04 × 5500 = 220

<u><em>End of 6 years:</em></u>

George: 215 × 6 = 1290

John: 220 × 6 = 1320

<u><em>John has earned the most interest at the end of 6yrs.</em></u><u><em> $1320</em></u>
