Answer:

Answer:

9.46 = y

Step-by-step explanation:

=================================================================

You have to use the cosine function equation.

cos(38) =

Multiply 12 on both sides.

12cos(38) = y

Solve.

9.46 = y

How to know which one to use:

Sin, Cos, Tan, Sec, Cosec, and Cot

Sin function is to do opposite number side length over the hypotenuse number side

Cos function is to do adjacent (side length that is next to angle) over the hypotenuse

Tan function is to do Opposite over Adjacent,

These are the inverse of each one

Sec is hypotenuse over opposite (inverse of Sin)

Cosec is hypotenuse over adjacent (Inverse of Cos)

Cot is Adjacent over Opposite (Inverse of Tan)

Answer:

y = 0.2·0.5^x

Step-by-step explanation:

An exponential function is generally of the form ...

y = a·b^x

where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.

In the given table, y = 0.2 for x = 0, so a = 0.2.

We find that the value for x = 1 is 0.1, so the value of b is ...

b = 0.1/0.2 = 0.5

Then the exponential function is ...

y = 0.2·0.5^x

Will give brainliest to correct answer.

Use Pythagorean's Theorem to find the length of x. $30^2-16^2=x^2$ so $900-256=x^2$ and $x= \sqrt{644}$ . We can simplify that radicand down into a perfect square times a prime number, and that is $\sqrt{4*161}$ . 4 is a perfect square that can be pulled out as a 2, so the length of x is $2 \sqrt{161}$ , the choice on the top right.

Answer:

The Answer would be Z.

Step-by-step explanation:

I took 30 from the image with a scale factor of 3 and divided it by 3. Now im at a scale factor of 1 and then i multiplied it by 2 to reach the scale factor of 2. I did this for every single side by dividing them by 3 and then mulitpiing them by 2. Therefore, i got the answer that model Z is your answer.

Line AC Line BC Line AB

30/3 = 10 24/3 = 8 18/3 = 6

10 x 2 = 20 8 x 2 = 16 6 x 2 = 12
