Using the compound interest formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Where:
A = Amount
P = Principal = $1821
r = Interest rate = 3% = 0.03
n = Number of times interest is compounded per year = 12

A researcher studied the relationship between the number of times a certain species of cricket will chirp in one minute and the temperature outside. Her data is expressed in the scatter plot and line of best fit below. What is the meaning of the yy-value on the line when x=80x=80?
Answers
The line of best fit approximates the relationship between the independent and the dependent variables. Here, the x-values give us the number of chirps per minute while the y-values give us the temperature in degrees Fahrenheit.
When x = 80, the number of chirps per minute is 80. The corresponding y is approximately 62.5 degrees Fahrenheit, which is the predicted temperature when the x-value is 80.
So, the answer is the first option: The predicted temperature in degrees Fahrenheit if the cricket has chirped 80 times.
The governor of state A earns $48,430 more than the governor of state B . If the total of their salaries is $279,100, find the salaries of each
Answers
For the first part, we can write
[tex]B+48430=A[/tex]where A is the salary for governor A and B is the salary for governor B.
From the second part, we can write
[tex]A+B=279100[/tex]Then, we have 2 equations in 2 unknows.
Solving by substitution method.
If we substitute the firs equation into the second one ,we get
[tex](B+48430)+B=279100[/tex]which gives
[tex]2B+48430=279100[/tex]If we move 48430 to the right hand side as -48430, we have

Find the minimum or maximum value of the function f(x)=10x^2+x−5. Give your answer as a fraction.
Answers
In order to find the minimum or maximum value of the function f(x),
[tex]f\mleft(x\mright)=10x^2+x-5[/tex]First, we have to find out at which value of x the function takes it. For example:
In order to find the value of x when it takes the maximum of minimum, we are going to analyze the derivative of the function. Then we are going to be following the next step-by-step:
STEP 1: finding the derivative of the function
STEP 2: analysis of the derivative of the function.
STEP 3: minimum or maximum value of the function
STEP 1: finding the derivative of the functionWe have that the derivative of the function is given by f'(x):
[tex]\begin{gathered} f\mleft(x\mright)=10x^2+x^1-5 \\ \downarrow \\ f^{\prime}(x)=2\cdot10x^{2-1}+1\cdot x^{1-1} \\ f^{\prime}(x)=20x^{2-1}+1\cdot x^0 \\ f^{\prime}(x)=20x^1+1\cdot1 \\ f^{\prime}(x)=20x^{}+1 \end{gathered}[/tex]Then, the derivative of f(x) is:
f'(x) = 20x + 1
STEP 2: analysis of the derivative of the function.We have that the function has a maximum or a minimum when its derivative takes a value of 0:
[tex]\begin{gathered} f^{\prime}\mleft(x\mright)=0 \\ 0=20x+1 \end{gathered}[/tex]when this happens, then, x has a value of:
[tex]\begin{gathered} 0=20x+1 \\ \downarrow\text{ taking -1 and 20 to the left side} \\ -1=20x \\ -\frac{1}{20}=x \end{gathered}[/tex]When x=-1/20, the function takes its minimum or maximum
STEP 3: minimum or maximum value of the functionNow, we can replace in the equation of f(x), to see what is the value of the function when x= -1/20:
[tex]\begin{gathered} f\mleft(x\mright)=10x^2+x-5 \\ \downarrow\text{ when x=}-\frac{1}{20} \\ f(-\frac{1}{20})=10(-\frac{1}{20})^2+(-\frac{1}{20})-5 \end{gathered}[/tex]Solving f(-1/20):
[tex]\begin{gathered} f(-\frac{1}{20})=10(-\frac{1}{20})^2+(-\frac{1}{20})-5 \\ \downarrow\sin ce(-\frac{1}{20})^2=\frac{1}{400} \\ =10(\frac{1}{400})-\frac{1}{20}-5 \\ =-\frac{201}{40} \end{gathered}[/tex]Then, the minimum value of the function is
[tex]f\mleft(x\mright)=\frac{-201}{40}[/tex]Answer: -201/40K

use the distributive property to write an equivalent expression for 88 plus 55
Answers
We are asked to use the distributive property to write an equivalent expression for 88 plus 55.
Let us first understand what is distributive property?
[tex]a\cdot(b+c)=a\cdot b+a\cdot c[/tex]The above property means that multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
But we have only two numbers 88 and 55 so how are we going to apply this property?
We need to break these numbers.
Let us find out the GCF (greatest common factor) of these two numbers.
11 is the greatest common factor of numbers 88 and 55
So, we can break the numbers as
[tex]\begin{gathered} 88=11\cdot8 \\ 55=11\cdot5 \end{gathered}[/tex]Now we have three numbers so let us apply the distributive property.
[tex]\begin{gathered} a\cdot(b+c)=a\cdot b+a\cdot c \\ 11\cdot(8+5)=11\cdot8+11\cdot5 \end{gathered}[/tex]Therefore, the equivalent expression for 88 plus 55 is

Answers
Explanation
The question wants us to obtain the perimeter of the paperboard that remains after the semicircle has been removed
To do so, we will follow the steps below:
Step1: Find the Perimeter of the rectangle
The perimeter of a rectangle is simply the sum of all its sides
So in our case, we will have to sum sides A as given below
[tex]Perimeter\text{ of rectangle= 21 +33+33= 87 inches}[/tex]Step 2: Find the perimeter of the semi-circle
The perimeter of a semi-circle is given by:
[tex]\begin{gathered} \frac{\pi D}{2} \\ where \\ \pi=3.14 \\ D=diameter\text{ of the semicircle =21 inches} \end{gathered}[/tex]Simplifying
[tex]Perimeter\text{ of semicircle=}\frac{3.14\times21}{2}=32.97\text{ inches}[/tex]Step 3: Find the sum of the perimeters of the rectangle and semicircle
Therefore, the perimeter of the paperboard that remains after the semicircle is removed will be
[tex]\begin{gathered} perimeter\text{ }of\text{ }the\text{ }rectangle+\text{ perimeters of the semicircle =87inches + 32.97 inches} \\ perimeter\text{ }of\text{ }the\text{ }rectangle-\text{ perimeters of the semicircle =119.97 inches} \end{gathered}[/tex]Hence, the perimeter of the paperboard that remains after the semicircle is removed will be 119.97 in
