Answer:

B

Step-by-step explanation:

For the function f(x) = x^2 + 2x - c  to have integer zeros it must factor. Substitute c for the values listed below and see which options factor.

A. 2  

f(x) = x^2 + 2x - 2 does not factor

B. 3  

 f(x) = x^2 + 2x - 3 does factor into (x + 3)(x - 1) so the zeros would be x = -3, 1

C. 4  

f(x) = x^2 + 2x - 4 does not factor

D. 6

f(x) = x^2 + 2x - 6 does not factor

<h3>Answer:</h3>

4. -3

5. 3

<h3>Step-by-step explanation:</h3>

4. For x > -2, the value of a is the slope of the line. The line goes down 3 units for each 1 to the right, so the slope is -3/1 = -3. Then a = -3.

___

5. The ordered pair (h, k) is typically used to name the point to which a function is translated. The vertex of the function f(x) = |x| is (0, 0). When it is translated to (h, k), the function becomes ...

... q(x) = |x -h| +k

If the new vertex is (3, 0), then h = 3 and k = 0. This is consistent with the equation shown. (k = 0 means q(x) = |x -h|.)

what is the area of the shaded sector of the circle if the radius is 14 ft? leave your answer in terms of pi
Strike441 [17]

Given:

Radius = 14 ft

θ = 45°

To find:

Area of the shaded sector

Solution:

Area of the sector formula:

$\text { area of sector }=\frac{\theta}{360^{\circ}} \times \pi r^{2}

                      $=\frac{45^\circ}{360^{\circ}} \times \pi \times 14^{2}

                      $=\frac{1}{8} \times \pi \times 196

                      =24.5\pi ft²

The area of the shaded sector of a circle is 24.5π ft².
