Which statement describes the symmetry of j(x)?
j(x) is an odd function.
j(x) is an even function.
j(x) is both an even and an odd function.
j(x) is neither an even nor an odd function.
Answers
Answer:
j(x) is an odd function
Step-by-step explanation:
We are given;
j(x) = 220/x³ and j(-x) = 220/(-x)³
Now,
when x = 1;
j(x) = 220/1³ = 220/1 = 220
j(-x) = 220/(-1)³ = 220/-1 = -220
When x = 2;
j(2) = 220/2³ = 220/8
j(-2) = 220/(-2)³ = -220/8
Now, Algebraically, function j would be even if and only if j(-x) = j(x) for all x in the domain of j. While j is odd if and only if j(-x) = -j(x) for all x in the domain of j.
From the values gotten, we can see that :j(-x) = -j(x). Thus, we can say that j(x) is an odd function.
Answer:
A) j(x) is an odd function.

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°

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:

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
A ream of a certain brand of paper weighs about 3.225 pounds. A ream contains 500 sheets of paper. How much does a sheet of paper weigh?
Answers
Answer:
A single sheet of paper should weigh: 0.00645 pound or [tex]6.45*10^{-3}[/tex] (in scientific notation)
Step-by-step explanation:
Divide 3.225 (the weight of the ream of paper) by 500 (the amount of paper in a ream).
If you need the scientific notation form, simply move the decimal point/place right or left until you end up with a whole number that is between 1 and 10 (in this case, 3 times to the right), then determine what power of 10 it should be, depending on the number of times you moved the decimal place (in this case, the power is -3).
The power/exponent is determined by the direction you have to move your decimal point, right=negative and left=positive. For example, if you started off with the number 6450, you would move the decimal point 3 times to the left and your power would be positive 3, which results in [tex]6.45*10^{3}[/tex].

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.

If there are 2.54 cm in 1 inch how long is a 36 inch long measuring stick in cm
Answers
Answer: The answer is 91.44 centimeters/cm
Step-by-step explanation:
2.54*36= 91.44 centimeters/cm
A 36-inch long measuring stick is equivalent to 91.44 cm.
To convert inches to centimeters, we can use the conversion factor:
1 inch = 2.54 cm
To find out the length of a 36-inch measuring stick in centimeters,
we multiply the length in inches by the conversion factor:
36 inches x 2.54 cm/inch
= 91.44 cm
Therefore, a 36-inch long measuring stick is equivalent to 91.44 cm.

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
