Answer: none of the above

Step-by-step explanation:

this is complementary angle meaning two angles have to add up to 90 degrees.

the only answer is 45 degrees which is not listed as an option so it is none of the above

What is the common ratio for the geometric sequence?

Helen [10]

Note this pattern: Mult. 24 by (-1/4) produces -6.
Mult -6 by (-1/4) produces 6/4 = 3/2
Mult. 3/2 by (-1/4) produces 3/8

Looks as though you copied the problem down incorrectly. You wrote 32 for 3/2 and -38 for -3/8.

The common ratio is -1/4.

write the equation in standard form of the function with x intercepts at (4,0) and (-2,0) that has been reflected across the x a

Anastaziya [24]

answer

$-3x^{2} +6x + 24$

explanation

since there are 2 x-intercepts, the lowest degree the function could possibly have is 2, so this could be the graph of a parabola

since our zeros are at x = 4 and x = -2, our factors are (x - 4) and (x + 2)

our equation so far is

(x - 4)(x + 2)

= $x^2 -4x + 2x - 8$

= $x^{2} -2x - 8$

since the function is reflected across the x-axis, multiply the equation by -1

$-(x^{2} -2x - 8)$

= $-x^{2} +2x + 8$

since the function has a vertical stretch of 3, multiply the equation by 3

$3(-x^{2} +2x + 8)$

= $-3x^{2} +6x + 24$
