I assume you need help with A. The points (7,9) (10,12) (13,9) creates the top of the kite. A forth points could be at (10, 4) The ex cord has to be at 10 because the center of the kite is x = 10. You could also use the point (10,3)

A student earned grades of C, A, B, and A. Those courses had these corresponding numbers of credit hours: 44, 66, 11, and

asambeis [7]

Answer:

The grade point average of the student is 49.92.

Step-by-step explanation:

A student earned grades : C, A, B, and A

Corresponding numbers of credit hours : 44, 66, 11, and 66

Assigns quality points to letter grades :

A = 4 , B = 3 , C = 2 , D = 1 , F = 0

The grade point average (GPA):

$\frac{\sum (\text{grade point}\times \text{credit hours})}{\sum (\text{grade point})}$

$=\frac{2\times 44+4\times 66+3\times 11+4\times 66}{2+4+3+4}$

$=\frac{649}{13}=49.9230\approx 49.92$

The grade point average of the student is 49.92.

Please can anybody help me with this:<br> Show that (x − 9)(x − 1) ≡ x^2 − 10x + 9

DanielleElmas [232]

We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.

Distribute and multipy out:

(x − 9)(x − 1)

x * x = x²

x * -1 = -x

x * -9 = -9x

-9 * -1 = 9

Add together:

x² + -x + -9x + 9

x² − 10x + 9

Use the Reflexive property:

x² − 10x + 9 = x² − 10x + 9 ✓
