Answer:

530.66 in.²

Step-by-step explanation:

Area of a circle = πr²

In the circle above, the diameter is given. To find the radius, you divide the diameter by 2, i.e.

Radius(r) = $\frac{26}{2} in.$

= 13 in.

∴Area of the circle = 3.14 × 13²

= 3.14 × 169

= 530.66 in.²

Select the correct answer from each drop down menu y=x^2+2x-1 y-3x=5

The drop down menus are not provided. However, I will help get the solution of the system of equation which is the requirement of the question.

Answer:
(3,14) and (-2,-1) are the solutions of the system

Explanation:
The first equation given is:
y = x² + 2x - 1 .........> equation I
The second given equation is:
y - 3x = 5
This can be rewritten as:
y = 3x + 5 ..........> equation II

Equate equations I and II and solve for x as follows:
x² + 2x - 1 = 3x + 5
x² + 2x - 1 - 3x - 5 = 0
x² - x - 6 = 0
(x-3)(x+2) = 0

either x-3 = 0 .........> x = 3
or x+2 = 0 ...........> x = -2

Now, we get the values of y by substituting in equation II as follows:
At x = 3:
y = 3x + 5
y = 3(3) + 5
y = 14
The first solution is (3,14)

At x = -2:
y = 3x + 5
y = 3(-2) + 5
y = -1
The second solution is (-2,-1)

Hope this helps :)

A ferris wheel can accommodate 55 people in Twenty minutes. How many people can ride the ferris wheel in 3 hours? What was the r

DerKrebs [107]

1 hour = 60 minutes.

60 minutes / 20 minutes = 3.

55 people x 3 = 165 people per hour. (Rate per hour)

165 people x 3 hours = 495 people. (Total people in 3 hours)
