Can someone help me with this math homework please!

Answer:

(B) 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:

You've probably seen this function notation format before, most likely f(x). Other common ones are g(x) and p(x). The f, g, and p are just function names, like the h in this question.

The t in the parentheses is the input, because it's the same as the t in 210 - 15t.

Together, h(t) is the output, which is the exact same as y if you used the formula y = mx + b.

Hope it helps (●'◡'●)

Pls help! evaluate the sine of the real number, pls give exact answers

Answer:

$-\frac{\sqrt2}{2} \\$ or exact is −0.70710678...

Step-by-step explanation:

Getting the point!

If we look at the unit circle and we find $-\frac{3\pi }{4}$ we see it is in the 3rd quadrant.
We know that all points in the 3rd quadrant have both negative x and negative y values.
We know that all radians with the base of 4 on the unit circle have the points of $(\frac{\sqrt{2}}{2} ,\frac{\sqrt{2}}{2})$
Because we are in the 3rd quadrant and both x and y are negative we know the point of $-\frac{3\pi }{4}$ is $(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2})$

Finding the sin!

Because we know that sin is asking us for the y value
We can just look at the point and find the y value!
the y value is $-\frac{\sqrt2}{2} \\$
Because this fraction does not need to be rationalized we are good!
Use a calculator to find the exact value and you get -0.70710678...
The final answer is $-\frac{\sqrt2}{2} \\$ or exact is −0.70710678...

Hope this helps!! Please mark Brainliest!
