If the following angle pairs are supplementary then what is the measure of the missing angle?
Answers
Answer:
c
Step-by-step explanation:
How to remember which is which? Well, alphabetically they are:
Complementary add to 90°
Supplementary add to 180°
You can also think:
"C" of Complementary is for "Corner" right angle(a Right Angle), and
"S" of Supplementary is for "Straight" (180° is a straight line)
Or you can think:
when you are right you get a compliment (sounds like complement)
"supplement" (like a vitamin supplement) is something extra, so is bigger

Simplify the expression (4 + 5i)(4 − 5i). 16 − 20i 16 + 20i −9 41
Answers
Answer:
41
Step-by-step explanation:
Simplify the following:
(5 i + 4) (-5 i + 4)
Hint: | Multiply 4 + 5 i and 4 - 5 i together using FOIL.
(4 + 5 i) (4 - 5 i) = (4) (4) + (4) (-5 i) + (5 i) (4) + (5 i) (-5 i):
4×4 + 4 (-5 i) + 5 i×4 + 5 i (-5 i)
Hint: | Multiply 4 and 4 together.
4×4 = 16:
16 - 5×4 i + 5 i×4 + 5 i (-5)×i
Hint: | Multiply 4 and -5 together.
4 (-5) = -20:
16 + -20 i + 5 i×4 + 5 i (-5)×i
Hint: | Multiply 5 and 4 together.
5×4 = 20:
16 - 20 i + 20 i + 5 i (-5)×i
Hint: | Combine products of like terms.
5 i (-5)×i = 5 i^2 (-5):
16 - 20 i + 20 i + -5×5 i^2
Hint: | Evaluate i^2.
i^2 = -1:
16 - 20 i + 20 i - 5×5×-1
Hint: | Multiply 5 and -1 together.
5 (-1) = -5:
16 - 20 i + 20 i - 5-5
Hint: | Multiply -5 and -5 together.
-5 (-5) = 25:
16 - 20 i + 20 i + 25
Hint: | Evaluate 16 - 20 i + 20 i + 25.
16 - 20 i + 20 i + 25 = 41:

5) Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her
house and her school. Given FG equals (2x) meters, GH = 1,000 meters, and FH equals 1.200 meters, what is z?
Answer:
Answers
Answer:
100 meters
Step-by-step explanation:
Given the following :
Alex house = F
Alex school = H
Alex bus stop = G
FG = 2x meters
GH = 1000meters
FH = 1200 meters
Hence,
FH = FG + GH
1200 = (2x + 1000) meters
1200 = 2x + 1000
1200 - 1000 = 2x
200 = 2x
x = 100meters
Hence, x = 100 meters

what are LOGARITHMS...???
Answers
Step-by-step explanation:
A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. ... Logarithms even describe how humans instinctively think about numbers.
Answer:
A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Just as an exponential function has three parts, a logarithm has three parts. The three parts of a logarithm are a base, an argument (also called power) and an answer.

Two angles are supplementary. One angle is 184° less than three times the other. Find the measures of the angles.
91°, 89°
96°, 84°
86°, 94°
90°, 86°
Answers
Answer:
91°, 89°Step-by-step explanation:
The sum of suplementary angles is allways 180°
so:
x - the other angle
3x - three times the other angle
180°- x - one angle
180° - x + 184° = 3x
364° = 4x
x = 91°
180°- x = 180° - 91° = 89°

Mr. and Mrs. Tournas know that their son will attend a college, in 14 years, that they estimate to cost approximately $250,000. How much should they deposit now if they assume that they can earn 8.5% compounded annually?
a) $72,083.41
b) $76,055.32
c) $75,450.20
d) $79,785.45
Answers
Answer: D
Step-by-step explanation:
We will try it to determine how much the need to save using the exponential function. In an exponential function,we need the start up amount and the common difference.
We know that the common difference is is 1.085 because if they will earn 8.5% interest plus 100% .
So 1.085 raised to the number of years times a number has to equal 250,000
x * 1.085^14 = 250,000 now solve for x
3.13340357495x = 250,000
x = 79785.44544 Rounded to the nearest cent is $79785.45
