Answer: A and B

<u>Step-by-step explanation:</u>

Here is Pascal's Triangle:


Row 1 (x + y)⁰                  1

Row 2 (x + y)¹               1     1

Row 3 (x + y)²             1    2   1

Row 4 (x + y)³           1   3    3   1

Row 5 (x + y)⁴         1   4   6   4   1

        ∵

Row n (x + y)ⁿ⁻¹      1 (sum of 2 digits above) 1


C and D are false.  A and B are the only correct answers

The circumference of a circle is 36π feet. What is the length of the radius of this circle?
kap26 [50]
<h2>Hello!</h2>

The answer is: The length of the ratio is 18 feet.

<h2>Why?</h2>

There are two ways to calculate the circumference of a circle:

C=\pi d\\C=2\pi r

Since we are looking for the length of the radius, let's work with the second formula.

From the statement we know that the circumference of the cirble is 36π, so we need to isolate the ratio:

C=2\pi r\\\\36\pi feet=2\pi r\\\\r=\frac{36\pi feet}{2\pi }=18feet

So, the length of the ratio is 18 feet.

Have a nice day!

write an equation of the line, in slope intercept form, that passes through the given point and has the given slope. point:(8,-8
denis23 [38]
If m equals 3, and we have a y and x value of 8 and -8, all we have to do is solve for b.

-8 = 3(8) + b
Multiply 8 and 3.
-8 = 24 + b
Subtract 24 from both sides to isolate b.
-32 = b

Your equation would look like this:

y = 3x - 32

IgorC [24]
So if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7
