Answer:
x = - 3 ± 3
Step-by-step explanation:
given the equation x² + 6x - 9 = 0
We can solve for x using the quadratic formula
x = ( - b ± ) / 2a
with a = 1, b = 6 and c = - 9
x = ( - 6 ± ) / 2
= ( - 6 ± ) / 2
= ( - 6 ± ) / 2
= ( - 6 ± 6 ) / 2
x = - 3 ± 3

Answer:
15 units.
Step-by-step explanation:
The hypotenuse of the smaller triangle = sqrt (3^2 + 4^2)
= sqrt 25 = 5.
As the scale factor is 1:3 the hypotenuse of the larger triangle = 5 * 3
= 15.
The formula for the volume of a pyramid with base B and altitude h is
A = (1/3)(B)(h).
Here, that comes to A = (1/3)(2^2)(1.5) = 2 cubic feet (ANSWER)
Answer: 124 ft after 0.5 seconds
Step-by-step explanation:
Find h(0.5)
h(0.5) = -16(0.5)^2 + 64(0.5) + 96
-16(0.25) + 64(0.5) + 96
-4 + 32 + 96
124
