what is the arc measure of ct in radians? what is the arc length in feet?
We will determine the arch lenght (In radians) as follows:
*First: We transform the measure of the angle from degrees to radians, that is:
[tex]\theta=80\cdot\frac{\pi}{180}\Rightarrow\theta=\frac{4\pi}{9}[/tex]*Second: We find the arc length:
[tex]s=r\theta\Rightarrow s=(13.2)(\frac{4\pi}{9})[/tex][tex]\Rightarrow s=\frac{88}{15}\pi[/tex]So, the arc length for CT is 88pi/15 radians.
*Third: We find its measure in feet:
[tex]s\approx18.43[/tex]So, the arch length for CT in feet is approximately 18.43 feet.

A cone has a volume of 3014.4 cubic inches and a radius of 12 inches.what is the height?
h = 20inches
Explanations:The formula for calculating the volume of a cone is expressed as:
[tex]V=\frac{1}{3}\pi r^2h[/tex]where:
r is the radius
h is the height
Given the following
r = 12 inches
V = 3014.4 cubic inches
Substitute to determine the height
[tex]\begin{gathered} 3014.4=\frac{1}{3}\times3.14\times12^2\times h \\ 3014.4\times3=452.16h \\ h=\frac{9043.2}{452.16} \\ h=20inches \end{gathered}[/tex]Hence the height of the cone will be 20inches

A golf lesson lasts from 10:00 am - 11:15 am and includes a 15 minutes break with equal lengths of time before and after the break is at 10:30 am.
Total lesson time is 1 hour and 15 minutes (10:00 - 11:15)
There is 15 minutes break with equal lengths of time before and after break.
The lesson before the break is from 10 - 10:30
Therefore , break is at 10:30 am
Lesson resumes at 10:45 when break is over then lesson runs another 30 minutes until 11:15 am (10:45 - 11:15).
Therefore, the break is at 10:30 am in mid of 10:00 am - 11:15 am.

A group of friends were working on a student film. They spent all their budget on equipment and props. They spent $369 on equipment and 55% of the total budget on props. What was the total budget for their student film
Answer: t = 820
Step-by-step explanation:
1) Set up the equation
369 + 55%t = t
2) Simplify the percentage
369+ 0.55t = t
3) Minus 0.55 t on both sides
369 = 0.45t
4) Set t by itself.
t = 820

Create a data set that has 4 values with a mode of 3, a median of 6, and a meanof 10
We are to create a data set of 4
that is a, b, c, d
mode means a number that occur the most
Median means the middle number
Mean means the average number
in the set, we must have a mode of 3
3, 3,
to get a median of 6, we need a number when we add to three and divide by 2 will give us 6
the number is 9
3 + 9 / 2
12/ 2 =
3, 3 , 9, d
the last number is d and it is unknown
since means is 10
mean = summation of all the numbers in the data set / the total number
the total number is 4
mean = 10
10 = 3 + 3 + 9 + d / 4
cross multiplication
10 x 4 = 3 + 3 + 9 + d
40 = 6 + 9 + d
40 = 15 + d
isolate d
d = 40 - 15
d = 25
therefore, the data set with a mode of 3, median of 6 and a mean of 10 are
3 , 3 , 9, 25
Find LM tangent angle circle
Applying the two-tangent theorem, the length of LM is: A. 18.
What is the Two-Tangent Theorem?The two-tangent theorem states that if two tangents are drawn from a circle to meet at a point outside the circle, then the tangent segments are congruent to each other, that is they have equal lengths.
Segments LK and LM are tangent segments drawn to meet at the external point L. This means, the length of Lk and the length of LM would be equal to each other.
LK = 4x - 2
LM = 3x + 3
LK = LM
Substitute
4x - 2 = 3x + 3
Combine like terms
4x - 3x = 2 + 3
x = 5
LM = 3x + 3
Plug in the value of x
LM = 3(5) + 3
LM = 15 + 3
LM = 18

Each theater sold tickets at ($7.50 a piece, if each theater received the same number of moviegoers, each theater make $6192.85 using arithmetic operations.
What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or more quantities. They cover topics like the study of numbers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry. Without applying the laws of arithmetic operations, we are unable to solve the issue. The four fundamental rules of mathematics are addition, subtraction, multiplication, and division.
Let the amount of each theater get be x,
No. of theaters are = 7
Cost of each ticket = $7.50
No. of people = 5780
Then we can say,

How many positive real zeroes does f(x) = x⁵ - 4x³ + 7x² + 3x - 5 have?
Given -
f(x) = x⁵ - 4x³ + 7x² + 3x - 5
To Find -
How many positive real zeroes does f(x) have =?
Step-by-Step Explanation -
We have
f(x) = x⁵ - 4x³ + 7x² + 3x - 5
where the signs of coefficients are:
+ - + + -
We can see there are three changes in the sign in f(x).
So, from
Descarte's rule,
there are either 3 0r 1 positive real roots
Now,
f(-x) = -x⁵ + 4x³ + 7x² - 3x - 5
Signs: - + + - -
So, here f(-x) has two sign changes.
From this we can conclude there is at least 1 real root and either 4, 2 or 0 imaginary roots.
Final Answer -
Positive real zeroes f(x) have =
Minimum = 1
Maximum = 3

Write a function to model the geometric sequence in the table. n: (1 2 3 4 5)a: (75 15 3 3/5 3/25)a) f(n) = 75 (1/5) nb) f(n) = 75 (1/5) n-1c) f(n) = 1/5 (75) nd) f(n) = 1/5 (75) n-1
First let's find the ratio of the sequence, by dividing one term by the term before:
[tex]\begin{gathered} \text{second term: 15} \\ \text{first term: 75} \\ ratio=\frac{15}{75}=\frac{1}{5} \end{gathered}[/tex]So the ratio is 1/5 and the first term is 75.
Now, we can use the following formula for the nth term of a geometric sequence:
[tex]a_n=a_1\cdot q^{n-1}[/tex]Where q is the ratio and a1 is the first term. So we have:
[tex]a_n=75(\frac{1}{5})^{n-1}[/tex]Substituting an by the function f(n), we have:

It is an ongoing function. A function from a set X to a set Y assigns exactly one element of Y to each element of X. The set X is known as the function's domain, and the set Y is known as the function's codomain.
What is function?In mathematics, a function is an expression, rule, or law that defines a connection between one variable (the independent variable) and another variable (the dependent variable).A function is defined as a relationship between a set of inputs and one output for each. A function is an input-output relationship in which each input corresponds to exactly one output.Every function has a domain and a codomain, as well as a range. In general, a function is denoted by f(x), where x is the input. A function is a type of rule that produces one output for one input.

What is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.
Given:
FG = 2 units, FI = 7 units, and HI = 1 unit
Now,
FI = FG+ GH +HI
