Name the property of real numbers illustrated by the equation. -2(x 4)=-2x-8
Distributive property of real numbers illustrated by the equation. -2(x 4)=-2x-8
The equation -2(x 4)=-2x-8 is an example of the distributive property of real numbers. This property states that when a number is multiplied by a group of numbers that are being added together, the number can be distributed to each of the terms in the group. To rewrite this equation as -2x + (-2)(-4) = -2x - 8, the number -2 is allocated to each of the terms in the group (x and -4) in this equation.Simplifying further, we get -2x - 8 = -2x - 8.
-2(x 4) = -2x - 8
Distribute -2 to each term in the group
-2x + (-2)(-4) = -2x - 8
Simplify
-2x - 8 = -2x – 8

Solve for y. Find m∠ C and m∠ D. Show all work.
The value of y is 10. The measure m∠ C and m∠ D are 40° and 76° respectively.
What is external angle?
The angle created when a transversal cuts one of two lines and is located outside of the line. It describes the angle between a side of a polygon and an expanded adjacent side.
The measure of an external angle of a triangle is equal to the sum of opposite interior angles.
∠DEF is an exterior angle. The opposite interior angles of ∠DEF are m∠ C and m∠ D
Therefore,
m∠ C + m∠ D = ∠DEF
4y° + (7y + 6)° = 116°
Add like terms
11y + 6 = 116
Subtract 6 from both sides:
11y = 110
Divide both sides by 11:
y = 10
Putting y = 10 in m∠ C = 4y° and m∠ D = (7y + 6)°
m∠ C = 40°
m∠ D = 76°

what is proportional relationship?
When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant.
Given x and y will have a proportional relationship if the ratio of x to y will be equal for all given values.
Given y is inversely proportional to x
When x=3, y=1/x = 8
So when x = 8 the value of y =3
Hence the value of y is 3 when the value of x is 8.

you are skiing down a mountain with a vertical height of 2900 feet. the distance from the top of the mountain to the base is 5800 feet. to the nearest degree, what is the angle elevation from the base to the top of the mountain?
Answer:
30°
Step-by-step explanation:
You want the angle of elevation to a point 2900 feet up that is 5800 feet distant on a straight line.
SineThe sine of the angle is the ratio of the height to the straight-line distance.
sin(θ) = h/d = 2900/5800 = 1/2
θ = arcsin(1/2) = 30°
The angle of elevation is 30° from the base to the top.
Answer: When doing a problem like this I always draw an example so I can see it. If you do that you see a right triangle with the hypothenuse, 2500 feet, is the distance from the top to the base. The opposite side is 1250 feet. Then remember sine= o/h, (opposite side over hypothenuse). So divide 1250/2500 and you get .5 Now take your calculator and use "inv" or sin-1 button to get the answer of the angle. x = 30
sinθ 1250/2500 = 1/2; θ = sin-1(1/2) = 30°

Using a mean and standard deviation as inputs, the following formula can be used to get the percentile of a normal distribution:
Percentile Value is equal to z +.
What is standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.
While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.
The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation.
Standard deviation may be written as SD.
A random variable, sample, statistical population, data set, or probability distribution's standard deviation is equal to the square root of its variance.
Though in algebra, it is simpler
According to our question-
a. 157 is less then 161

Mr.eder’s dog is on a special diet from the vet. The dog is to eat 1/4 kg of food per day. Me.Eder buys a 6 pound bag of dog food. If mr.Eder follows the vet’s diet, how many days will this bag of food last
For 10 days that bag will last when Mr. Eder's buys 6 pound bag of dog food, using kg to pound conversion and simple basic arithmetic operation.
How to convert kg to pound ?
We know that 1 Kg = 2.20 pound.
The dog is to eat 1/4 * 2.20 = 0.55 pound food
Weight of bag brought by him = 6 pound
The basic operations are :
Addition : (+) To get sum of two or more values
e.g. a = 3, b = 5
Addition = 3+5
= 8
Subtraction : (-) The result of subtraction is the “difference”
e.g. Subtraction of a and b = a-b
= 3-5
= -2.
Multiplication : (*) The result of multiplication is the “product”
e.g. Multiplication of a and b = 3*4
= 12
Division : (/) The result of division is the “quotient”
e.g. Division of 4 and 2 is = 4/2
= 2.
so, the number of days bag can be used = 6/0.55
= 10.90
So, the bag can be used for complete 10 days.

The solution is
a) The compound interest for the second period is $ 2.01 and the amount after the second period is $ 404.01
b) The compound interest for the first period is $ 114.125 and the amount is $ 18,374.125
The compound interest for the second period is $ 114.83828125 and the amount after second period is $ 18,488.96
What is Compound Interest?
Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
a)
Let the principal be P = amount after first period = $ 402
Now , the rate of interest r = 6 %
The compound interest is calculated by compounding monthly
Now , the interest for the second period = ( PRT / 100 x 12 )
Substituting the values in the equation , we get
The interest for the second period = ( 402 x 6 x 1 ) / 1200
The interest for the second period = $ 2.01
The amount after the second period = amount after first period + interest for the second period
The amount after the second period = 402 + 2.01
The amount after the second period = $ 404.01
b)
Let the principal be P = $ 18260
The rate of interest r = 2.5 %
The compound interest is calculated by compounding quarterly
Now , the interest for the first period = ( PRT / 4 x 100 )
Substituting the values in the equation , we get
The interest for the first period = ( 18260 x 2.5 ) / 400
The interest for the first period = 45650 / 400
The interest for the first period = $ 114.125
The amount for the first period = 18260 + 114.125
The amount for the first period = $ 18,374.125
Now , the principal for the second period = interest + amount of first period
The principal for the second period = $ 18,374.125
The rate of interest = 2.5 %
The interest for the second period = ( PRT / 4 x 100 )
Substituting the values in the equation , we get
The interest for the second period = ( 18374.125 x 2.5 ) / 400
The interest for the second period = 45935.3125 / 400
The interest for the second period = $ 114.83828125
The amount for the second period = 18,374.125+ 114.84
The amount for the second period = $ 18,488.96
Hence , the amount and interest is calculated

Let f(x) = e ^ (6x) and g(x) = 8in(x) Find and simplify g(f(- 2)) -96 -48 48 C B A
Answer: g(f(-2))=-96
Step-by-step explanation:
[tex]Given: \ f(x)=e^{6x}\ \ \ \ g(x)=8ln(x)\ \ \ \ g(f(-2))=?\\\\f(-2)=e^{6*(-2)}\\\\f(-2)=e^{-12}\\\\Hence,\\\\g(f(-2))=8ln(e^{-12})\\\\g(f(-2))=8*(-12)\\\\g(f(-2))=-96[/tex]
Answer:
-96
Step-by-step explanation:
Given:
[tex]\begin{cases}f(x)=e^{6x}\\ g(x)=8 \ln (x) \end{cases}[/tex]
To find g[f(-2)], substitute x = -2 into the function f(x):
[tex]\implies f(-2)=e^{6 \times -2}=e^{-12}[/tex]
Then substitute the function f(-2) in place of the x in function g(x):
[tex]\implies g[f(-2)]=8 \ln \left(e^{-12}\right)[/tex]
[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]
[tex]\begin{aligned}\implies g[f(-2)]&=-12\cdot 8 \ln \left(e\right)\\&=-96 \ln \left(e\right)\end{aligned}[/tex]
Apply the log law: ln(e) = 1
[tex]\begin{aligned}\implies g[f(-2)]&=-96 \ln \left(e\right)\\&=-96(1)\\&=-96\end{aligned}[/tex]
---------------------------------------------------------------------
As one calculation:
[tex]\begin{aligned}g[f(-2)]&=8 \ln \left(e^{6 \times -2}\right)\\& = 8 \ln \left(e^{-12}\right)\\& = -12 \cdot 8 \ln \left(e\right)\\& = -96(1)\\& = -96\end{aligned}[/tex]

what is the equation for a cosecant function with vertical asymptotes found at x equals pi over 4 plus pi over 4 times n comma such that n is an integer?
The answer is that the the equation for a cosecant function with vertical asymptotes found at x equals pi over 4 plus pi over 4 times n comma such that n is an integer is 2 coscec 4x.
Cosecant is one of the trigonometric ratios . It is calculated as the ratio of the hypotenuse to the perpendicular of a right triangle. It is also calculated as the reciprocal of the sine function.
Now, here if the vertical asymptotes is x = pi/4 + pi/4 (n).
This is not defined when n=0.
so, when x= pi/4,
sin 4x = sin x = 0
which means w =0 .
and we get the equation for cosecant function to be f(x)= 2 cosec 4x since cosec x = 1/ sin x.

if the average height of a male in the u.s. is 70 inches and the standard deviation of male heights is 3 inches, what is the probability that a randomly selected male will be between 70 and 73 inches? (assume a normal distribution.)
The probability of men whose height falls between 70 and 73 inches is 0.273. Therefore, the percent of men whose height falls between 70 and 73 inches is 27.3%. Therefore, the solution is 27.3%.
The standard deviation is a quantity that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.
We are informed that the heights of men in the U.S are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. We need to determine the percent of men whose height falls between 70 and 73 inches. We would first evaluate the probability that the height of a randomly selected individual would fall between 70 and 73 inches;
This can be done in stat-crunch;
Click Stat, highlight on Calculators then click Normal
In the pop-up window that appears click Between
Enter the given values of mean and standard deviation; 70 and 3 respectively
Enter the values 70 and 73 in the next set of boxes in that order
Finally, click on compute;
Stat-Crunch returns a probability of 0.273. Therefore, the percent of men whose height falls between 70 and 73 inches is 27.3%. Therefore, the solution is 27.3%.
