Answer:

The answer to your question is:

p₁ = - 2 + $\sqrt{-2}$

p₂ = -2 - $\sqrt{-2}$

Step-by-step explanation:

p² + 4p = -6

p² + 4p + (2)² = - 6 + (2)²

(p + 2)² = - 2

p + 2 = ± $\sqrt{-2}$

p = -2 ± $\sqrt{-2}$

p₁ = - 2 + $\sqrt{-2}$ p₂ = -2 - $\sqrt{-2}$

For a recent year, 38 more Democrats than Republicans represented a country. If the total number of representatives of the count

Fantom [35]

Second question isn't well formatted

Answer:

Number of republicans = 207

Number of democrats = 245

Step-by-step explanation:

Let :

Number of republicans = x

Number of democrats = x + 38

Total number of representatives from the two parties = 452

Tge number of representatives from each party can be calculated thus ;

Number of democrats + number of republicans = total number of representatives

(x + 38) + x = 452

x + 38 + x = 452

2x = 452 - 38

2x = 414

x = 414 / 2

x = 207

Number of republicans = 207

Number of democrats = 207 + 38 = 245

Are these the choices? <span>Cost, Time, Pace, Materials?

I think the answer would be - it is a measure of the efficiency of the materials used in the car. Since this talks about how many gallons of gas a drive of 25 miles would consume. </span>

Find the area and perimeter.

yan [13]

Answer:

Area = 33√3

Perimeter = 122

Step-by-step explanation:

This is a parallelogram and perimeter for a parallelogram is calculated by adding side length to base and that's multiplied by 2

perimeter (6 + 11) × 2 = 122

The area is calculated by multiplying height to the base

there's a 30° 60° 90° special triangle inside the parallelogram and the side length that sees 60° in this special triangle is 3√3 so this is our height and base is given as 11

Therefore the area of this parallelogram is

3√3 × 11 = 33√3

A farmer is tracking the amount of corn his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 50 models

polet [3.4K]

Answer:

The crop yield increased by 9 pounds per acre from year 1 to year 10.

Step-by-step explanation:

To solve this we are using the average rate of change formula: $Av=\frac{f(x_2)-f(x_1)}{x_2-x_1}$ , where:

$x_2$ is the second point in the function

$x_1$ is the first point in the function

$f(x_2)$ is the function evaluated at the second point

$f(x_1)$ is the function evaluated at the first point

We know that the first point is 1 year and the second point is 10 years, so $x_1=1$ and $x_2=10$ . Replacing values:

$Av=\frac{-(10)^2+20(10)+50-[-(1)^2+20(1)+50]}{10-1}$

$Av=\frac{-100+200+50-[-1+20+50]}{9}$

$Av=\frac{150-[69]}{9}$

$Av=\frac{150-69}{9}$

$Av=\frac{81}{9}$

$Av=9$

Since $f(x)$ represents the number of pounds per acre and $x$ the number of years, we can conclude that the crop yield increased by 9 pounds per acre from year 1 to year 10.
