Since we know one root, which is -3, we can use synthetic division to find (x+3) would need to be multiplied by to get the original polynomial. Then, we factor the quadratic to find the other two factors, which are 1/2 and -2

What is the distance between the points (-9,5) and (8,5)

TiliK225 [7]

Answer:

17 units

Step-by-step explanation:

Use distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , to find the distance between (-9, 5) and (8, 5):

Let,

$(x_1, y_1) = (-9, 5)$

$(x_2, y_2) = (8, 5)$

Plug in the values into the distance formula:

$d = \sqrt{(8 - (-9))^2 + (5 - 5)^2}$

$d = \sqrt{(17)^2 + (0)^2}$

$d = \sqrt{(289 + 0)}$

$d = \sqrt{289}$

$d = 17$

The circumference of a great circle of a sphere is 44π. Find the Surface Area of the sphere.

alexdok [17]

Answer:

1936 π square units

Step-by-step explanation:

Given the information:

The circumference of a great circle of a sphere is 44π.

As we know the formula used to find a circle's circumference is:

C = 2πr , where r is the radius of the circle

In this situation, we know C = 44π

<=> 2πr = 44π

<=> r = 22 units

Hence, the Surface Area of the sphere

S.A = 4π $r^{2}$

= 4π $22^{2}$

= 1936 π square units
