1 answer:
miv72 [106K]3 years ago
8 0

Answer:

B

Step-by-step explanation:

In the right triangle with hypotenuse of 10 use the sine ratio to find x

sin20° = \frac{opposite}{hypotenuse} = \frac{x}{10}

Multiply both sides by 10

10 × sin20° = x, hence

x ≈ 3.4 ( to the nearest tenth ) → B

Can some one help with the following please…???
LenaWriter [7]

Answer:

5. 8

6. 18

Step-by-step explanation:

5.

a(a^2 + a - 1) + 7 =

= a^3 + a^2 - a + 7

For a = -1,

= (-1)^3 + (-1)^2 - (-1) + 7

= -1 + 1 + 1 + 7

= 8

6.

2ab(a + b) - 3ab(a - b) =

= 2a^2b + 2ab^2 - 3a^2b + 3ab^2

= -a^2b + 5ab^2

For a = 1 and b = 2,

= -(1)^2(2) + 5(1)(2)^2

= -1(2) + 5(4)

= - 2 + 20

= 18
