Answer

a) 2π

Step-by-step explanation:

We can easily solve this question by using a graphing calculator or any plotting tool, to check if it is periodic.

The function is

f(x) = 3*sin(2*x) + 4*cos(3*x)

Which can be seen in the picture below

We can notice that f(x) is periodic. It has periodic amplitudes, and the function has a period T = 6.283 ≈ 2π

The maximum and minimum values are

Max = 6.695

Min = -6.695

Answer:

The height of the given rectangular prism is 5cm.

Step-by-step explanation:

Given that the volume of the rectangular prism is $5cm^3$

And length is $\frac{3}{4}$ and width is $1\frac{1}{3}$

That is V=5cm^3[/tex] , $l=\frac{3}{4}cm$ and $w=1\frac{1}{3}cm$

We have the volume of the rectangular prism V=lwh cubic centimeter

$V=lwhcm^3$

Substituting the values in above formula

$5=\frac{3}{4}\times 1\frac{1}{3}\times h$

$5=\frac{3}{4}\times \frac{4}{3}\times h$

$5=1\times h$

$5=h$

Rewritting as below

$h=5cm$

Therefore the height is 5cm

In 12 games last season the school baseball team scored 5, 11, 2, 0, 4, 8, 9, 6, 7, 4, 1, and 2 runs. What is the average number

Mashcka [7]

Hello there!

First, we need to put our data set into proper numerical order (least to greatest).

Set: , 1,2,2,4,4,5,6,7,8,9,11

Now, to find the mean, we need to add them all up.

1 + 2 + 2 + 4 + 4 + 5 + 6 + 7 + 8 + 9 + 11 = 59

Then, divide it by how many numbers there are : 12

59 divided by 12 = 4.9166667

Round it to the nearest tenth.

4.9166667 = 4.9

This means the average number of runs scored per game is 4.9 runs.
