Answer:

[tex]k = -\frac{7}{3}[/tex]

Step-by-step explanation:

Given :

p(x) = 2x² − 3kx + 5

Since, -1 is a zero for p then :

p(-1) = 0

Solving the equation p(-1) = 0 for k :

p(-1) = 0

⇔ 2(-1)² − 3k(-1) + 5 = 0

⇔ 2 + 3k + 5 = 0

⇔ 3k = -5 - 2

⇔ 3k = -7

⇔ k = -7/3

NOTE :

If -1 is a zero of p

[tex]\Longrightarrow k = -\frac{7}{3}[/tex]

[tex]\Longrightarrow p(x) = 2x^2 - 3(\frac{-7}{3}) x + 5\\\Longrightarrow p(x) = 2x^2+ 7x + 5[/tex]

The perimeter of the rectangle ABCD is 13.7 inches.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

⇒ sin30° = AD/AC

⇒ AD = AC(sin30°) = 5(1/2)

⇒ AD = 2.5 inches

⇒ sin60° = CD/AC

⇒ CD = AC(sin30°) = 5(√3/2)

⇒ CD = 4.33 inches

The perimeter of rectangle ABCD = 2(AD) + 2(CD)

The perimeter of rectangle ABCD = 2(2.5) + 2(4.33) = 5 + 8.66

Rounded to the nearest tenth

The perimeter of rectangle ABCD = 13.66 ≈ 13.7 inches

Answer:

y = x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3 ) and (x₂, y₂ ) = (2, 4 )

m = [tex]\frac{4-3}{2-1}[/tex] = [tex]\frac{1}{1}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (1, 3 )

The amount  that Athena will be charged for interest is $22.19

What is the meaning of APR of 16.99%?

The APR means an annual percentage rate, which means that the 16.99% is annual interest rate compounded monthly, hence, it needs to be divided by 12 in order to determine the equivalent monthly interest rate.

monthly interest rate=16.99%/12

monthly interest rate=0.0141583333333333

The monthly interest charged on the balance of $1,567.32 is computed thus:

The area of polygon A would be a fraction 1/25 of the size of polygon B.

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object

The formula of the scale factor is shown as;

Area of Polygon B = (scale factor)²×(Area of Polygon A).

Using a scale factor of 5, we get

(Area of Polygon B)  = (5)²× (Area of Polygon A)

(Area of Polygon B) = (25) × (Area of Polygon A)

Area of Polygon A = (1/25) × Area of Polygon B

Therefore, the area of polygon A would be a fraction 1/25 of the size of polygon B.

The equation that we would use to find the value of x based on the area of a rectangle is:

C. (16 + 2x)(12 + 2x) = 396

To find the area of a rectangle, find the product of its length and its width. Thus, the area of a rectangle is: (length)(width) = area.

Given the following:

Area of both the walkway and the garden = 396 square meters

Length = x + 16 + x = 16 + 2x

Width = x + 12 + x = 12 + 2x

Using the area formula for a rectangle, we would have:

(16 + 2x)(12 + 2x) = 396.

Therefore, the equation that we would use to find the value of x based on the area of a rectangle is:

C. (16 + 2x)(12 + 2x) = 396

The minimum electric rate in cents per kwh for which the 12-year total cost will be less for the first freezer is 8.61 cents

Let x =  minimum electric rate (Cents/kWh)

Total months in 12 years is 12*12 = 144 m

1st freezer

Total cost over 12 years is

623.95 (cost) + (90 kWh/m)*(144 m)(x/100 $/kWh)

= 623.95 + 129.6x

2nd freezer

Total cost over 12 years is

500 + 100*144*(x/100)

= 500 + 144x

For the 1st freezer to cost less over 12 years,

623.95 + 129.6x < 500 + 144x
