Answer:
It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).
Step-by-step explanation:

Patrick is x years old . His brother is 9 years older than he is .If his brother is y years old, express y in terms of x
Answer:
y = x + 9 ( in years)
Step-by-step explanation:
Given that Patrick is x years old and his brother is 9 years older than he is. Then;
His brother's age will be
= x + 9
If his brother is y years old then
y = x + 9
Since y is the subject, y has been expressed in terms of x. Where y is the age of Patrick's brother and x is Patrick's age.
A formula used for calculating volume of a cylinder is V=πr2h
Rearrange the formula so that the height, h , of the cylinder can be determined given the volume, V and the radius, r .
h=Vπr2−−−√
B
h=πr2V
C
h=Vπr2
D
h=πr2−−−√V
Answer:
V=πr2h
h=V/πr2
the answer is h=v/πr2
The Harvey family stayed at a hotel for n nights. The cost was $80 per night plus a one-time fee of $20 because they brought their dog. Which expression represent the total cost of their hotel stay.
80n + 20n
80n + 20
80 + 20n
80 + 20 + n
Answer:
80n + 20
Step-by-step explanation:
20 stays the same because it's a one time fee. Then, for every night the Harvey family stays, it costs them eighty dollars. So, it's 80n + 20
Answer: 80n+20
Step-by-step explanation:
80 is the cost of nights you stayed but you don’t know the number of nights they dated so you place n next to 80 and they payed an additional 20 fee so you add that to 80n

Anybody good in geometry and know the answer? Free Brainliest and point !!
Answer:
5,8
Step-by-step explanation:
since C is on y coordinate 8 if its a reflection C' will be as well and C is on x coordinate -5 so if its a reflection then C' will be 5 so 5,8
Answer:
(5,8)
Step-by-step explanation:
one way I like to do it is a) count how many squares C is away from the axis, which is 5, and then staring at the Y-axis count five spaces to the right, or b) which might be a little more time consuming, do where the original D is and see how many spaces up and across C is from D, which is up two and right 5. So then go to the new one, and go up two and instead of going right five, count five to the left because it's reflected. Hope that made sense and helped! If not please let me know and i'll try to explain further.

Answer:
3) [tex]all \: real \: numbers[/tex], [tex]( - \infty , \infty )[/tex], or [tex]- \infty \leqslant x \leqslant \infty[/tex] (same thing)
4) [tex] - \infty < y < 0[/tex] or [tex]( - \infty ,0)[/tex] (same thing)
5) [tex]-2[/tex] or [tex](0, -2)[/tex] (same thing)
Step-by-step explanation:
3) Domain represents the amount of [tex]x[/tex]-values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be [tex]all \: real \: numbers[/tex], [tex]( - \infty , \infty )[/tex], or [tex]- \infty \leqslant x \leqslant \infty [/tex](same thing).
4) Range represents the amount of [tex]y[/tex]-values in a function. The function goes downward forever ([tex] - \infty < y[/tex]) by the indication of an arrow and halts just under the y-axis ([tex]y < 0[/tex]). After combining these two inequalities, you see that the range is [tex] - \infty < y < 0[/tex] or [tex]( - \infty ,0)[/tex] (same thing).
5) The [tex]y[/tex]-intercept is where the function crosses the [tex]y[/tex]-axis. In this function, the [tex]y[/tex]-intercept is [tex]-2[/tex] or [tex](0, -2)[/tex] (same thing).
