Answer:

10) C

11) C

Substitute all values of x in y = 3x + 2 to solve

y = 3(0) + 2 = 2

y = 3(2) + 2 = 8

y = 3(3) + 2 ≠ 5

y = 3(5) + 2 = 17

7. An investment account pays 3.9% interest compounded semi-annually. If

Likurg_2 [28]

Answer:

the balance would be 48000

Step-by-step explanation:

First you really dont have to do with the 3.9%

If 4000 is invested and you need the balance after 12 years you just multiply

4000 times 12=48000

Angle A and Angle B are supplementary angles. The ratio of the measure of Angle A to the measure of Angle B is 5:4. Find the mea

tatyana61 [14]

Answer:

Angle A = 100°

Angle B = 80°

Step-by-step explanation:

Supplementary angles sum 180°

Angle A to Angle B ratio is 5:4, you can write that ratio using a factor.

Angle A = 5x

Angle B = 4x

Since the sum is 180°

Angle A + Angle B = 180°

5x + 4x = 180°

9x = 180°

x = 20°

Replacing x = 20°

Angle A = 5(20°) = 100°

Angle B = 4(20°) 80°

Show me how to do this please for geometry!!

ololo11 [35]

Answer:

see explanation

Step-by-step explanation:

Since the triangles are right use trigonometric ratios to find x and y

sin33° = $\frac{adjacent}{hypotenuse}$ = $\frac{2.5}x}$

Multiply both sides by x

x × sin33° = 2.5 ( divide both sides by sin33° )

x = $\frac{2.5}{sin33}$ ≈ 4.590

tan33° = $\frac{opposite}{adjacent}$ = $\frac{2.5}{y}$

Multiply both sides by y

y × tan33° = 2.5 ( divide both sides by tan33° )

y = $\frac{2.5}{tan33}$ ≈ 3.850

cos72° = $\frac{adjacent}{hypotenuse}$ = $\frac{6}{x}$

Multiply both sides by x

x × cos72° = 6 ( divide both sides by cos72° )

x = $\frac{6}{cos72}$ ≈ 19.416

tan72° = $\frac{y}{6}$

Multiply both sides by 6

6 × tan72° = y, thus

y ≈ 18.466
