Answer:

y = 4 (Answer C)

Step-by-step explanation:

We want to find side y. The sine function relates the 30 degree angle, the hypotenuse 8 and the opposite side y:

y

sin 30 degrees = 1/2 = -----------

How do u regroup when u find the sum of 64+43

Anarel [89]

What we are going to do is use the DISTRIBUTIVE PROPERTY. This distributive the numbers, to make it easier to solve.

So we will break 64 up.

64 = 60 + 4

43 = 40 + 3

60 + 40 = 100

4 + 3 = 7

100 + 7 = 107

So, 64 + 43 = 107.

Answer:

Step-by-step explanation:

Step 1

we know that sinθ = opp/hyp

so

let x = hyp

sin(23.64) = 5.42/x

0.40=5.42/x

x0.40 = 5.42

x = 13.55

Thefore the length of the hypothenuse is 13.55 Send Love:333

Neveah has created the function f(x) =the quantity of 2x plus 4, divided by 3 to represent the growth of her hair, where x repre

dangina [55]

Given that:

The function to represent the growth of Neveah hair is

$f(x)=\dfrac{2x+4}{3}$

where, x represents the number of months since her last hair cut.

To find:

The inverse of function and time when her hair will have grown 6 inches.

Solution:

We have,

$f(x)=\dfrac{2x+4}{3}$

Put f(x)=y.

$y=\dfrac{2x+4}{3}$

Interchange x and y.

$x=\dfrac{2y+4}{3}$

Isolate y.

$3x=2y+4$

$3x-4=2y$

$\dfrac{3x-4}{2}=y$

Put $y=f^{-1}(x)$ .

$f^{-1}(x)=\dfrac{3x-4}{2}$

So, the required inverse function is $f^{-1}(x)=\dfrac{3x-4}{2}$ . It represents the number of months to grow her hair x inches.

She can predict when her hair will have grown 6 inches by putting x=6 in the inverse function.

Put x=6 in the inverse function.

$f^{-1}(6)=\dfrac{3(6)-4}{2}$

$f^{-1}(6)=\dfrac{18-4}{2}$

$f^{-1}(6)=\dfrac{14}{2}$

$f^{-1}(6)=7$

Therefore, growth of her hair is 6 inches in 7 months.
