How do you find square roots? Example: Square root of 441.

The graph of the function f(x) = 5 cos (2x) is a reflection over the x-axis of the graph of g(x) =

Zarrin [17]

Answer:

$g(x)=-5\cos (2x)$

Step-by-step explanation:

The given function is

$f(x)=5\cos (2x)$

If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.

$P(x,y)\Rightarrow P'(x,-y)$

If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is

$g(x)=-f(x)$

Substituting the value of function f(x), we get

$g(x)=-5\cos (2x)$

Therefore, the required function is $g(x)=-5\cos (2x)$ .

Renting a canoe in a nautical center costs $ 5 per hour and $ 5 for each additional hour. Determine the equation of the function

nasty-shy [4]

Answer: 5 + 5w

Step-by-step explanation:

We can use the variable x to describe each additional hour, although the vairable can be substituted for any other vairable.

We know that the main cost for one hour is $5, and that each additional hour will cost $5.

Therefore, the equation to reflect this situation would be 5 + 5w, because the first 5 represents the first hour, and the 5w represents how much each hour costs. If you rent two extra hours, then the cost would end up being 15, because the equation would become: 5 + (5x2) = 15.

The equation is 5 + 5w. Hope this helps, and good luck!

5x + 2 = 8x + 5 Help me before I die quick math is so hardddddd

attashe74 [19]

Answer:

x = -1

Step-by-step explanation:

Note: when you send a number across it can change it sign. If it is positive it will turn negative.

5x + 2 = 8x + 5

Send 8x across

5x + 2 - 8x = 5

send 2 across

5x - 8x = 5 - 2

- 3x = 3

Divide both sides by - 3

- 3x/- 3 = 3/- 3

- 3 cancel out - 3

x = 3/ - 3

3 divided by - 3 is - 1

x = -1

What is the volume of this container?

zmey [24]

Answer:

504 in³

Step-by-step explanation:

this is a rectangular prism and the volume formula is v = l * h * w

so now

v = l*w*h

v= 6*8*12

v = 576 inch³

that's not the answer, that's the volume for whole thing but there is a gap and we have to subtract it from the whole volume. you can look at the option and say it's 504 inch³ from common sense. here is the work:

the gap has 2 inch length, 6 inch width and 6 in height.

v = l*h*w

v = 6 * 2 * 6

v= 72 inch

now subtract the gap volume from total volume so

576 - 72 = 504 in³
