Well 40 times 6 is 240 which means that you don't have to round.

All you do is cover the zero in forty and do four times six and when you get the answer add zero to the end of the number.

Help ASAP!!<br>Using the graphed function above, find the following
Alenkinab [10]

Answer:

Maximum: 1, Minimum: -3, Midline y = -1, Amplitude = 4, Period = \pi, Frequency \displaystyle =\frac{1}{\pi},  equation : f(x)=-4cos(2x)+1

Step-by-step explanation:

<u>Sinusoid Functions</u>

It refers to the oscillating functions like the sine or cosine which range from a minimum and maximum value periodically.

The graph shown can give us all the information we need to answer these questions:

Maximum: 1

Minimum: -3

The midline goes through the center value (mean) of the max and min values, i.e.

Equation of the midline:

\displaystyle y=\frac{1-3}{2}=-1

Amplitude is the difference between the maximum and minimum values

A=1-(-3)=4

The period is the time it takes to complete a cycle. We can see the minimum value is first reached at x=0 and next at x=\pi

Thus the period is

T=\pi

The frequency is the reciprocal of the period:

\displaystyle f=\frac{1}{T}=\frac{1}{\pi}

The angular frequency is

\displaystyle w=2\pi f=\frac{2\pi }{\pi}=2

The equation of the function is a negative cosine (since it starts at the minimum) or a shifted sine or cosine. We'll choose the negative cosine, knowing all the parameters:

f(x)=-4cos(2x)+1

Lin knows that there are 4 quarts in a gallon. She wants to convert 6 quarts to a gallon, but cannot decide if she should multip
defon

Given:

There are 4 quarts in a gallon.

She wants to convert 6 quarts to a gallon.

To find:

Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.

Solution:

We have,

4\text{ quarts}=1\text{ gallon}

1\text{ quarts}=\dfrac{1}{4}\text{ gallon}

6\text{ quarts}=\dfrac{6}{4}\text{ gallon}

Here, 6 quarts is equal to \dfrac{6}{4} gallon. It means we need to multiply 6 by 4 in 4\text{ quarts}=1\text{ gallon} to find the answer.

Please need help on this
Trava [24]

Answer:

The perimeter of a shape is the sum of the measurements of all sides. Since a rectangle have equal lengths and widths, you can just add the numbers twice.

So, 15 + 15 + 8 + 8. So the perimeter is 46 cm.
