The radius of a circle is 10 inches. What is the angle measure of an arc bounding a sector with area 10π square inches?
Answer:
Step-by-step explanation:
hello :
the arc length formula is : s = 2πr(θ/360°)
given : area : s = 10 , radius : r = 10
2(3.14)(10)(θ/360°)=10 solve for : θ
2(3.14)(θ/360°)=1
θ = 360°/6.28
θ = 57°.32

for the function y=2+5 sin(pi/12(x-2)), what is the maximum value
Answer:
3
Step-by-step explanation:
the maximum value of the function y = -2+5sin(pi/12(x-2)) is determined by taking the first derivative of the function. The first derivative is equal ( 5 pi/ 12 )* sin ((pi/12) (x-2)) = 0. x is equal to 4472 through the calculator. Substituting to the original equation, the maximum value is 3.

Integers Multiple Choice Read the word problem and circle the corresponding expression. 1. Jaimie withdrew $25 from his TFSA (Tax-Free Savings Account), 4 times. Which expression shows the change in his savings account?
a) (-25)(4)
b) (-25)(-4)
c) −25 4
d) 25 4 2.
Answer:
a) (-25)(4)
Step-by-step explanation:
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. In this case,
withdrew means no longer there which means subtracted.
Then, times mean multiply.
Therefore, -minus twenty-five times (x) four
combine them and it equals (-25)(4)
7. A scatter plot was created to show the relationship
between the number of staff members and students
at various schools. The scatter plot's trend line has an
equation of y = 0.1x + 18, where y is the total number
of staff members and x is the total number of
students.
Use the equation to predict the number of students in
a school with 120 staff members.
A. 1,038 students
B. 30 students
C. 890 students
D. 1,020 students
Answer:
1020 students
Step-by-step explanation:
Given the trend line equation :
y = 0.1x + 18,
where y is the total number of staff members and x is the total number of students.
Using the equation, the predicted number of students in a school with 120 staffs ;
y = 120
y = 0.1x + 18
120 = 0.1x + 18
120 - 18 = 0.1x
102 = 0.1x
x = 102 / 0.1
= 1020 students

What is quotient of 2x3 + 3x2 + 5x - 4 divided by x2 + x + 1
The quotient is the outcome of the division one number or expression known as the dividend, by another number or expression known as the divisor
The option that gives the correct quotient is;
[tex]\mathbf{2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}}[/tex]
Where, the quotient is 2·x + 1, and the reminder is 2·x - 5
The reason the above option is correct is as follows:
The given dividend is 2·x³ + 3·x² + 5·x - 4
The divisor is x² + x + 1
By long division of a polynomial we have;
2·x + 1(Quotient)
(2·x³ + 3·x² + 5·x - 4) ÷ (x² + x + 1 )
2·x³ + 2·x² + 2·x
0 + x² + 3·x - 4
[tex]{}[/tex] x² + x + 1
[tex]{}[/tex] 0 + 2·x - 5
Therefore, we have;
[tex]\dfrac{2\cdot x^3 + 3 \cdot x^2 + 5 \cdot x - 4}{x^2 + x + 1} = 2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}[/tex]
Therefore, the correct option is;

The population, P, of Johnstown over a period of t years since the town
was founded can be estimated by P = 5,600e0.0591
In approximately how many years after the town's founding will the
population reach 11,200?
Answer:
12 years
Step-by-step explanation:
Given that
P = 5,600 e^0.0591
Reaching amount = 11,200
time period = t
We need to find out the time period i.e. t
So,
11,200 = 5,600 e^0.0591t
2 = e^0.0591t
Now take the log on both the sides
ln2 = 0.0591t ln
t = ln2 ÷ 0.059
= 0.693147÷ 0.059
= 11.748

Answer:
15) 30°
16) 49.5°
Step-by-step explanation:
15) We solve using the Trigonometric function of Sine
sin θ = Opposite/Hypotenuse
Opposite = 12
Hypotenuse = 24
sinθ = 12/24
θ = arc sin(12/24)
= 30°
Approximately = 30°
16)We solve using the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = 13
Hypotenuse = 20
cos θ = 13/20
θ = arc cos (13/20)
= 49.458398126°
Approximately = 49.5°

Answer:
5y + 2y - 4x + 4x = -7 +14
7y = 7
y = 1
2(1) + 4x = 14
4x = 12
x = 3
Step-by-step explanation:
Using the process of elimination
Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.
When y is found, input it into the second equation to find x.
a woman sold an article for 400.00and made a profit of 25%,Find ty cost price and profit
Answer:
$100 profit, $300 cost
Step-by-step explanation:
So 25% of $400 is $100, now we know she made $100 on the article
and the other $300 was the amount used to make the article i'm asuming
A woman sold an article for 400.00
made a profit of 25%
Cost price and profit is $100 profit, $300 cost.
What are the 4 types of profit?There are four levels of profit or profit margins: gross profit, operating profit, pre-tax profit, and net profit.
These are reflected on a company's income statement in the following sequence: A company takes in sales revenue, then pays direct costs of the product of service.
What is profit and example?Profit is a term that often describes the financial gain a business receives when revenue surpasses costs and expenses.

The height of the wall from the least to the greatest is : [tex]\frac{5}{2}[/tex], 2.6, 1 + √3 , √8
In order to order the numbers from the least to the greatest, all the measurements have to be in the same form.
Currently, there are not so they would need to be changed to the same form.
I would change all numbers to decimals
√8 = 2.83
5/2 = 2.5
2.6
1 + √3 = 1 + 1.73 = 2.73
Now that all the numbers are in decimal, they can now be ordered
