Harrizon [31]
Well, remember we can't take the square root of a negative

so we see that we have \sqrt{1-x^2}
so find those values that take sqrt of a negative and restrict hem from the domain
anny value greater than 1 and less than -1
so domain is from -1 to 1, including those numbers
D=[-1,1]

a. D=[-1,1] or from -1 to 1 is domain


b. for a TI-84, go to y-editor then input 4x \sqrt{1-x^2} for y1

c. for a TI-84, click 2nd then window (gets to tbset) scrol down to set Δx to 0.1, then cilick 2nd again then click graph (to select table) and scroll down till you see that value of y that is the biggest, that value is x=0.7



A. domain is from -1 to 1

Brad has two lengths of copper pipe to fit together one has a length of 2 5/12 feet and the other has a length of 3 7 12 ft how
leva [86]
To find the total length of the two copper pipes, we need to add them together.

2 5/12 + 3 7/12 = 5 12/12

Since 12/12 = 1 or a whole, we can simplify this further.

5 12/12 = 6

Hope this helps!

What is the mean and median of the lengths . <br> 10,31,36,36,38,42,47,48,49,and 52
Olin [163]

Answer:

Mean = 38.9  Median = 40

Step-by-step explanation:

When you find mean, you must add all the numbers together then divide by the amount of numbers.

10+31+36+36+38+42+47+48+49 + 52

==> 389

There are 10 numbers.

389 / 10

==> 38.9

To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.

(x + y ) / 2

38 + 42

==> 80

Divide by 2

80 / 2

==> 40
