Answer:

y = (x + 3)² - 7

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

To obtain this form use the method of completing the square

Given

y = x² + 6x + 2

add/subtract ( half the coefficient of the x- term)² to x² + 6x

y = x² + 2(3)x + 9 - 9 + 2

= (x + 3)² - 7

Solve the triangle. A = 48°, a = 32, b = 27

astraxan [27]

Answer:

C) B = 38.8°, C = 93.2°, c ≈ 43

Step-by-step explanation:

For triangle: a / sin A = b / sin B = c / sinC

32 / sin 48° = 32 / 0.743

32 / 0.743 = 27 / Sin B sin B = 0.627

C = 180 - 48 - 38.8 = 93.2° sin C = sin 93.2° = 0.998

32 / 0.743 = c / 0.998 = 42.98 (<u>≈ 43</u>)

Find the solutions to x2 = 24.

iren [92.7K]

Answer:

x = ± 2 $\sqrt{6}$

Step-by-step explanation:

Given

x² = 24 ( take the square root of both sides )

x = ± $\sqrt{24}$ = ± $\sqrt{4(6)}$ = ± $\sqrt{4}$ × $\sqrt{6}$ = ± 2 $\sqrt{6}$
