The sketches show the graphs y=-x^2+16 and y=7

Tanzania [10]

Answer:

7 = -x^2 +16

x^2 -16 = 7

x^2 -23 = 0

Using quadratic equation

x = -0 +- sqrt (23^2 - 4*1*23) / 2 * 1

x = sqrt (0 - -92) / 2

x = sqrt (92) / 2

x1 = 4.7958

x2 = -4.7958

Answer:

11. $b = 30$

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

Substitute

$16^{2} + b^{2} = 34^{2}$

$256 + b^2 = 1156$

$b^2 = 1156-256\\b^2 = 900$

$b = \sqrt{900}$

$b = 30$

Your welcome and don't forget to say <u>Thanks</u>
