Answer:

∠1 = 64°

∠2 = 116°

Step-by-step explanation:

Let x = supplement and x + 52 = the one angle. Set up this equation:

(x) + (x + 52) = 180

2x + 52 = 180

Subtract 52 from both sides.

2x = 128

Divide both sides by 2, and you get x = 64.

Keep in mind this equals the supplement. To find the measure of the other angle, add 52 and you get 116

A student needs to make a circular cardboard piece with an area between 154 square inches and 616 square inches. The function f(
Nezavi [6.7K]
The area of the circle by definition is given by:
 f (r) =  \pi  * r ^ 2

 For f (r) = 154:
 154 =  \pi  * r ^ 2

 Clearing r we have:
 r ^ 2 = 154 / 3.14

 r =  \sqrt{154/3.14} 

 r = 7
 For f (r) = 616:
 616 = \pi * r ^ 2
 Clearing r we have:
 r ^ 2 = 616 / 3.14 r = \sqrt{616/3.14} r = 14
 Answer:
 
a reasonable domain for f (r) is:
 
7 <r <14

uranmaximum [27]
$1100 x 1.021^7 = $1272 (whole number.)

the $1100 is the original amount of money put in the bank with the 1.021 being the interest rate. this was put to the power of 7 to represent the years the money will be in the account.

What are the coordinates of the vertex for f(x) = x2 + 4x + 10?
MAVERICK [17]
You have to complete the square to get it into vertex form.  Do this by setting the function equal to zero and at the same time moving the constant over to the other side of the equals sign so you have this: x^{2} +4x=-10.  Now we can complete the square on the polynomial by taking half the linear term, squaring it, and adding it to both sides.  Our linear term is 4. Half of 4 is 2, and 2 squared is 4, so we add 4 to both sides: ( x^{2} +4x+4)=-10+4 and simplify to get ( x^{2} +4x+4)=-6.  In this process we have created a perfect square binomial on the left, which happens to be (x+2) ^{2}=-6.  Now move the -6 back over by addition to get (x+2) ^{2} +6=y.  The vertex is found at (-2, 6), the third choice down.

Planes Q and R are parallel. Explain how you know lines a and b are skew.

Answer:

We don't know that they skew but if Q and R are the same length then they aren't. But if Q and R are different lengths then they are skew. It would help to post a picture.
