The ratio of the number of girls to the number of all students in the class is 4 to 9. Can there be 20 students in that class?
Masteriza [31]

Answer:

No

Step-by-step explanation:

  1. 20 ÷ 9 = 2.222222222
  2. 9 does not go evenly into 20, and there can't be a fraction of a student, so the answer is no.

I hope this helps!

Which of these nonterminating decimals can be converted into a rational number? Plz help
Archy [21]

Answer:

0.02020202...  = 2/99.

Step-by-step explanation:

This is a repetitive decimal number . It can be converted to a rational number:

.020202,  * 100  = 2.0202...

.020202  * 1       = 0 0202....

Subtract

0.020202 * 99   =   2

So 0.020202.. = 2/99.

What transformations are needed to change the parent cosine function to y=3cos(10(x-pi))?
LUCKY_DIMON [66]

Answer:

The graph of y=cos(x) is:

*Stretched vertically by a factor of 3

*Compressed horizontally by a factor  \frac{1}{10} .

*Moves horizontally \pi units to the rigth

The transformation is:

y=3f(10(x-\pi))

Step-by-step explanation:

If  the function y=cf(h(x+b))  represents the transformations made to the graph of y= f(x)  then, by definition:

If  0 then the graph is compressed vertically by a factor c.

If  |c| > 1 then the graph is stretched vertically by a factor c

If c  then the graph is reflected on the x axis.

If b> 0 The graph moves horizontally b units to the left

If b The graph moves horizontally b units to the rigth

If 0 the graph is stretched horizontally  by a factor \frac{1}{h}

If h> 1 the graph is compressed horizontally by a factor \frac{1}{h}

In this problem we have the function y=3cos(10(x-pi)) and our parent function is y = cos(x)

The transformation is:

y=3f(10(x-\pi))

Then c =3>1  and b =-\pi < 0 and h=10 > 1

Therefore the graph of y=cos(x) is:

Stretched vertically by a factor of 3.

Also as h=10 the graph is compressed horizontally by a factor  \frac{1}{10} .

Also, as b =-\pi < 0 The graph moves horizontally \pi units to the rigth
