A garden is made up of two squares and a quarter circle. What is the area of the garden?
Elanso [62]

9514 1404 393

Answer:

  100.27 ft^2

Step-by-step explanation:

The area of each square is ...

  A = s^2 = (6 ft)^2 = 36 ft^2

The area of the 1/4 circle is ...

  A = 1/4πr^2 = 1/4π(6 ft)^2 = 9π ft^2 ≈ 28.27 ft^2

__

The area of the garden is the sum of the areas of the quarter circle and the two squares:

  A = 28.27 ft^2 + 2×36 ft^2 = 100.27 ft^2

The area of the garden is about 100.27 square feet.

Write a polynomial in standard form with the zeros -4,0, 1, and 4.
gavmur [86]

Answer: x^4-x^3-16x^2+16x

Step-by-step explanation:

Factor theorem : If x=a is a zero of a polynomial p(x) then (x-a) is a factor of p(x).

Given: Zeroes of polynomial : -4,0, 1, and 4.

Then Factors = (x-(-4)), (x-0), (x-1) and (x-4)   [By factor theorem ]

=(x+4), (x-0), (x-1) and (x-4)

Multiplying these factors to get polynomial in standard form.

(x+4)\times(x-0)\times(x-1)\times(x-4)  \\\\= x(x+4)(x-4)(x-1)\\\\= x(x^2-4^2)(x-1)\\\\= x(x^2-16)(x-1)\\\\= x(x^2-16)(x-1)\\\\=x(x^2x+x^2\left(-1\right)+\left(-16\right)x+\left(-16\right)\left(-1\right))\\\\= x(x^3-x^2-16x+16)\\\\=x^4-x^3-16x^2+16x

Hence, B is the correct option.

The price of gas is $2.15 / gallon today. Last week it was $2.55 for a gallon of gas. What was the percent change in the price?
pickupchik [31]

Answer:

15.69% decrease

Step-by-step explanation:

To find the percent change, we take the original price and subtract the new price

2.55 -2.15 = .40

Divide by the original price

.40/2.55

.156862745

Multiply by 100%

15.6862745 %

Since the price went down, this is a decrease

15.69% decrease
