Hello I’m doing my math homework I just need the answers for 23 and that’s just it . ABCDEF all right thank you please get me ASAP,
Answer:
A. -9, -6, 8, 13
B. -4/5, -1/2, -.2, .25
C. -8/3, -2 1/2, 9/2, 4.75
D. -8, -3, -1, 4
E. -1/2, -1/4, .5, 3/4
F. -3/2, -5/4, -4/5, 1.5
Step-by-step explanation:
The easiest thing to do is to put them all in the same format. Fractions are just division problems, so just divide. 4/5 is 4 divided by 5, which is .8.
Remember, the farther a negative number is from 0 on the number line, the smaller it is. So, -8 is smaller than -5. -5 is smaller than -2, etc.
Please solve the equation
[tex]5 {}^{2x + 1} - 26(5 {}^{x} ) \: + 5 = 0[/tex]
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
[ log 5 = 0.69 ]
[ log 26 = 1.41 ]
The formula for log [tex]x^n[/tex] = n log x
The value of x is 0.043
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
[tex]5^{2x + 1} - 26(5^x) + 5 = 0[/tex]
[tex]5^{2x + 1} + 5 = 26(5^x)[/tex]
The formula for log [tex]x^n[/tex] = n log x
Taking logs on both sides.
log [tex](5^{2x + 1} + 5)[/tex] = log [tex]26(5^x)[/tex]
log [tex]5^{2x + 1}[/tex] + log 5 = log 26 + log [tex]5^{x}[/tex]
(2x + 1) log 5 + log 5 = 1.41 + x log 5
[ log 5 = 0.69 ]
[ log 26 = 1.41 ]
(2x + 1) x 0.69 + 0.69 = 1.41 + 0.69x
1.39x + 0.69 + 0.69 = 1.41 + 0.69x
0.70x = 1.41 - 1.38
x = 0.03 / 0.70
x = 0.043
Thus,
The value of x is 0.043

DUE TOMORROW PLS HELP!!
does anyone know how to solve the area and perimeter for this parallelogram pls help!!! In details !!!
Answer:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is a measurement of the surface of a shape. for example
You are able to find the perimeter of the rectangle by adding length and width and multiplying by two because the opposite sides of a rectangle are equal in length. Both lengths of the rectangle are the same, and both widths are the same. For example, P = 2 * (14 + 8) = 2 * (22) = 44 centimeter (17.3 in).

an experimenter would like to construct a 99% confidence interval with a width at most 0.5 for the average resistance of a segment of copper cable of a certain length. if the experimenter knows that the standard deviation of such resistances is 1.55. how big a sample should the experimenter take from the population? what happens if the standard deviation and the width of the confidence interval are both doubled?
64 is the standard deviation and the width of the confidence interval are both doubled .
What is standard deviation in math?
Your dataset's average level of variability is represented by the standard deviation. It reveals, on average, how far away from the mean each value is. A low standard deviation denotes that values are grouped close to the mean, whereas a large standard deviation shows that values are often far from the mean.Margin of error(E)=0.5
Standard deviation(σ)=1.55
Significance level(α)=100%-99%=1% or 0.01
From Z distribution Critical value table
the Critical value(Zc)=2.58 at significance level=0.01
we know formula for the Margin of error
E = Zc * σ/√n
0.5 = 2.58 * 1.55/√n
√n = 2.58 * 1.55/0.5
√n = 3.999/0.5
√n = 7.998
n = ( 7.998)²
n = 63.968004

One share of kimcos common stock pays an annual dividend of 1. 43. Today kimco closed at 19. 09 with a net cahnge of +0. 72. The stock yield yesterdays closing price is about 8
With a net change of +0.72 yesterday's closing price was 19.81 and stock dividend yield for yesterday's closing price is 7.2%.
How to calculate the Dividend Yield?
To calculate dividend yield, all you have to do is divide the annual dividends paid per share by the price per share.
Dividend Yield = Annual Dividends Paid Per Share / Price Per Share
According to the given question:
Net change = today's price - yesterday's price
0.72 = 19.09 - yesterday's price
∴ Yesterday's price = 19.81
Stock dividend yield
= (1.43/19.81) x 100
= 7.2%
Therefore the stock yield of yesterday's closing price is 7.2%

The average rate of change of function [tex]g(x)=5(2)^{x}[/tex] from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.
The correct option is (A).
What is the average rate of change of a function?
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.
Using function notation, we can define the Average Rate of Change of a function f from a to b as:
[tex]rate(m) = \frac{f(b)-f(a)}{b-a}[/tex]
The given function is [tex]g(x) = 5(2)^{x}[/tex],
Now calculating the average rate of change of function from x = 1 to x = 2.
[tex]m = \frac{g(b)-g(a)}{b-a}\\ m = \frac{g(2)-g(1)}{2-1}\\\\m=\frac{5(2)^{2}-5(2)^1}{2-1}\\ m=\frac{10}{1} \\m=10[/tex]
Now, calculate the average rate of change of function from x = 3 to x = 4.
[tex]m = \frac{g(b)-g(a)}{b-a}\\ m = \frac{g(4)-g(3)}{4-3}\\\\m=\frac{5(2)^{4}-5(2)^3}{4-3}\\ m=\frac{40}{1} \\m=40[/tex]
The jump from m = 10 to m = 40 is "times 4".
So option (A) is correct.
Hence, The average rate of change of function [tex]g(x)=5(2)^{x}[/tex] from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.

The possible dimension of the triangular garden assuming it to be a right-angle triangle is (12,2),(8,3), and (4,6).
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The area of a triangle is given as (1/2) × base × height.
The given area of the triangle = 12 feet².

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
As per the given,
Let's say the cost per pound of strawberry taffy is "s" and the cost per pound of banana taffy is "b".
Then, the cost of 8 pounds of strawberry taffy and 3 pounds of banana taffy will be,
8s + 3b = 66
And,
The cost of 10 pounds of strawberry taffy and 3 pounds of banana taffy will be,

assuming that earth is a sphere of radius 6378 kilometers, what is the difference in latitude of two cities, one of which is 1046 kilometers due north of the other?
The difference between the distance between the two cities if of 14.842 latitudes.
The earth has one latitude running right in the center called the equator. On either side of the equator, there are 90 more latitudes each.
Therefore, the earth has 181 latitudes.
Now if we see the image we can see that all these latitudes fall on the vertical diameter of the Earth.
Hence the distance covered by all 181 latitudes = 2 X radius of the Earth
= 2 X 6378 km
= 12756
Assuming that all the latitudes are equidistant, we get the distance between 2 latitudes to be
12756/181
= 70.475 km
Let the two cities be A and B. It is given that the distance between the two cities is 1046 km and one is due north of the other.
Therefore the difference in latitudes between the two cities is
