Need help with finding A and B
Maslowich

Hello!

First of all, let's find A. This is the opposite and hypotenuse we will be dealing with. Therefore, we will use the sin.

sin30= 0.5

This gives us the equation below.

a/12=0.5

a=6

Now we find b. This is the adjacent and hypotenuse. Therefore, we will use the cosine.

cos30≈0.87

This gives us the equation below.

b/12=0.87

b=10.44

I hope this helps!

Which statement best describes the function h(t) = 210 – 15t?
Serjik [45]

Right answer is:

h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.

Step-by-step explanation:

Lets define the terms first

An independent variable is a variable whose values are put in the function. It is the input of a function.

While dependent variable's value depends on the independent variable.

Given function is:

h(t) = 210-15t

By observing the function, we can see that the function is in terms of t which means that t is the input for the function while h is the name of the function. h(t) which be obtained by putting the values of t is the output.

So,

Right answer is:

h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
