Answer:

x = 74.2°

Step-by-step explanation:

Complementary angles are two angles whose sum is 90°.

Let x = the second angle

15.8° + x = 90°

x = 90 - 15.8°

x = 74.2°

(x + 2)(x + 3)(x + 4) can be written in the form x + ax² + bx + c

ELEN [110]

Answer:

$a=9, b=26, c=24$

Step-by-step explanation:

Let's expand the expression bit by bit.

$(x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6$ by FOIL.

We have that $(x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24$ .

So, the answer is $\boxed{a=9, b=26, c=24}$

natka813 [3]

Answer:

5000 X (0.96)^n

$3607

Step-by-step explanation:

Profit decreases at a rate of 6% per year = 100 - 6 = 96%

In year 1, profit would be = 5000 x 0.96 = 4800

In year 2 = 5000 x 0.96^2 =

5000 X (0.96)^n

5000 X (0.96)^8 = $3607

Solve 2y - 5 over 3 = 4y - 1 over 2

ololo11 [35]

$\frac{2y - 5}{3} = \frac{4y - 1}{2}$
$3(4y - 1) = 2(2y - 5)$
$3(4y) - 3(1) = 2(2y) - 2(5)$
$12y - 3 = 4y - 10$
$8y - 3 = -10$
$8y = -7$
$\frac{8y}{8} = \frac{-7}{8}$
$y = -0.875$
