For a width of 25, the length will also be 25, so the area is 25² = ...
  625.

_____
The rule is
  area = width×(50 -width)

Which is the best approximate solution of the system of linear equations y= 1.5x - 1 and y = 1
yan [13]

Answer:

4/3

Step-by-step explanation:

We can immediately eliminate y by setting y = 1 equal to y = 1.5x - 1:

1 = 1.5x - 1, or 1.5x = 2, or x = 2/1.5 = 4/3

What transformations are needed to change the parent cosine function to y=3cos(10(x-pi))?
juin [17]

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

If 10% of a number is 16, find 5% of that number.
sukhopar [10]

Answer:

5% = 8

Step-by-step explanation:

Since 10% of a number is 16, multiply that by 10 to get 160. In order to get 5%, divide 10% (16) by 2 to get 8, which is 5% of 160.
