1 answer:

7 0

The sine increases from 0 to 90 degrees and from 270 to 360 degrees
The sine decreases from 90 to 270 degrees

The cosine increases from 180 to 360 degrees
The cosine decreases from 0 to 180 degrees

Sine = 0 at 0 and 180 degrees

Cosine = 0 at 90 and 270 degrees

Can someone actually answer this question pls its my 3rd time posting it and ill ive gotten was wrong or answers that make no se

Answer:

(-2+-5) equals -7.

Because the signs are the same, we dont change it.

(3+5) equals 8. Same like the other equation, the signs are the same so we do not change it.

Now we do (-7+8) The answer will be 1. Lets use a little graph since its hard to explain.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8

Mark -7 anyway you want. (Circle it, draw a line under it, what ever you want.)

Now Move the line 8 times.

When you do that your line will stop at 1.

And thats how you do it.

Describe the end behavior of the following function: F(x)=2x^4+x^3

Anika [276]

Answer:

Rises to the left and rises to the right.

Step-by-step explanation:

Since, the given function is f(x)= $2x^{4}+x^{3}$ , and the end behavior of the given function is determined as:

Consider the given function f(x)= $2x^{4}+x^{3}$ , identify the degree of the function:

The degree of the function is : 4 which is even

And then identify the leading coefficient of the given function that is +2 which is positive in nature.

Hence, the function is positive and even in nature, therefore, the end behavior of the function will be rising to the left and rising to the right.

A 6-pack of capri-Suns costs $8.80 .How much would a 24-pack cost if the costs are proportional

andrew11 [14]

Now, in a 6-pack, there are 6 bottles, 6-pack.

in a 24-pack, there are 24 bottles, 24-pack.

so, if 6 bottles, cost 8.80, how much will it be for 24 bottles then?

$\bf \begin{array}{ccll}
bottles&price\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
6&8.80\\
24&p
\end{array}\implies \cfrac{6}{24}=\cfrac{8.80}{p}\implies p=\cfrac{24\cdot 8.80}{6}$

What is the y-intercept of the line shown below? <br> A. 5<br> B. -5<br> C. 2<br> D. -2

lys-0071 [83]

Answer: -2

Step-by-step explanation: The y-intercept of a line is the point where the graph crosses or intersects the y-axis.

In this case, the line crosses the y-axis 2 units down from the

origin and we can write the coordinates of the point as (0, -2).

So the answer is -2.

Sphinxa [80]

Answer:

is proportional

Step-by-step explanation:

The ratio between words and minutes is a constant, so the relationship is proportional.
