Answer:
6
Explanation:
First, we find the squares of 5 and 6.
[tex]\begin{gathered} 5^2=25 \\ 31-25=6 \end{gathered}[/tex][tex]\begin{gathered} 6^2=36 \\ 36-31=5 \end{gathered}[/tex]We conclude therefore that the square root of 31 is closer to 6 since it has a smaller difference.
what are the two moves you can use to get the first figure to the second figure (dilation,rotation, reflection,and translation)
ANSWER:
Dilation and translation
EXPLANATION:
Looking at the figures, the two moves used to get the first figure to the second figure is dilation and translation.
The figure was translated 6 units right and 7 units down.
The translation rule that occured here is==> (x+6, y-7)
Also, a dilation with a scale factor of 2 occured here.
Therefore, a dilation and translation occured in order to get the first figure to the second figure.
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(x+9)°
42°
104°
Answer:
Step-by-step explanation:
first do 104 + 42 it should be 146
second since it is x+9 do 146 - 189, it should be 43.
third check your work by doing 43 + 146
if it equals 189 then do 43 - 9, you should get 34
so x = 34

If an investment grew to $13,500 in 2 years and the interest amount earned was $1,150, calculate the nominal interest rate compounded quarterly.
The nominal interest rate compounded quarterly is 1.33%.
Given,
If an investment grew to $13,500 in 2 years.
and, the interest amount earned was $1,150.
To find the nominal interest rate compounded quarterly.
What is nominal interest rate?
The interest rate before inflation is referred to as the nominal interest rate.
Nominal can also refer to the advertised or stated interest rate on a loan, excluding any fees or interest compounding.
Now, According to the question:
Here given ,
P = $13500
i = ?
A = $1150
t = 2 yrs
n = 4 x 2 = 8
Formula of compound interest ,
A = P( 1 + I )ⁿ
$1150 = $13500 ( 1 + i ) ⁸
$1150 / $13500 = (1 + i)⁸
0.0851 = (1+ i) ⁸
1 +i = 8√.0851
1 + i = 2.33
i = 2.33 -1
i = 1.33 %
Hence, The nominal interest rate compounded quarterly is 1.33%.

The break even point is where cost is equal to revenue
cost : y = 25.96x + 22752
Revenue : y = 57.56x
Set the two equations equal to determine x
25.96x + 22752 = 57.56x
Subtract 25.96x from each side
25.96x-25.96x + 22752 = 57.56x-25.96x
22752 = 31.6x
Divide each side by 31.6
22752/31.6 = 31.6x/31.6

This type of function is non linear.
Define function.A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output. You can tell if a relation is a function by looking at the inputs (the x-coordinates) and outputs (the y-coordinates). Keep in mind that each input has only one output in a function. A function is an equation with a single solution for y for each value of x. Each input of a particular type receives exactly one output when using a function.
Given,
f(x) = x²

the sum of the reciprocal of two consecutive positive integers is 17/72. Write an equation that can be used to find the two integers. What are the integers?
Answer:
[tex]\frac{1}{x}+\frac{1}{x+1}=\frac{17}{72}[/tex]The two consecutive positive integers are 8 and 9.
Explanation:
Let the 1st positive integer be x and the 2nd be x + 1, so their reciprocal will be 1/x and 1/x+1.
The equation can then be written as;
[tex]\frac{1}{x}+\frac{1}{x+1}=\frac{17}{72}[/tex]To solve for x, the 1st step is to find the LCM of the left-hand side of the equation;
[tex]\begin{gathered} \frac{(x+1)+x}{x(x+1)}=\frac{17}{72} \\ \frac{2x+1}{x(x+1)}=\frac{17}{72} \end{gathered}[/tex]We can equate the numerators and solve for x as shown below;
[tex]\begin{gathered} 2x+1=17 \\ 2x=17-1 \\ x=\frac{16}{2} \\ x=8 \end{gathered}[/tex]If the 1st positive integer, x, is 8, therefore the 2nd integer, x + 1, will be;

She also invests$2,400 in an online savings account whichgives 5.3% simple annual interest. After fiveyears, which one will have earned moreinterest, and how much more interest will ithave earned, to the nearest dollar?
The formula for determining simple interest is expressed as
I = PRT/100
where
I = interest
P = principal or amount invested
T = time in years
R = interest rate
Considering the amount invested in her local bank,
P = 3760
R = 1.8
T = 5
I = (3760 x 1.8 x 5)/100 = 338.4
Considering the amount invested in online savings,
P = 2400
R = 5.3
T = 5
I = (2400 x 5.3 x 5)/100 = 636
After 5 years, the investment in the online savings account earned more interest.
The difference in interest earned is
636 - 338.4 = $298 to the nearest dollar
It has earned $298 more than the local bank's interest

Measurement is the quantification of an object's or event's properties for comparison with other objects or occurrences. Measurement, in other terms, is the act of establishing how large or little a physical amount is in comparison to a fundamental reference quantity of the same sort. The scope and use of measurement are context and discipline dependent. Measurements do not apply to nominal qualities of things or events in natural sciences and engineering, which is compatible with the recommendations of the International Bureau of Weights and Measures' International lexicon of metrology. However, measures in other domains, such as statistics and the social and behavioral sciences, can have numerous levels.
