Answer:
0 degrees
Step-by-step explanation:
To find m/YAI, we need to first find the measure of angle KAI, which is the sum of angles KAY and LAI. Then, we can find the measure of angle YAI by subtracting the measure of angle KAI from 180 degrees.
Using the angle addition postulate, we know that:
m/KAY + m/LAI = m/KAI
Substituting the given values, we get:
4x + 39 + 12x - 9 = m/KAI
Simplifying the expression, we get:
16x + 30 = m/KAI
Now, we need to solve for x. To do this, we can use the fact that angles KAY and LAI are supplementary (add up to 180 degrees) since they form a straight line. Thus:
m/KAY + m/LAI = 180
Substituting the given values, we get:
4x + 39 + 12x - 9 = 180
Simplifying the expression, we get:
16x + 30 = 180
Subtracting 30 from both sides, we get:
16x = 150
Dividing both sides by 16, we get:
x = 9.375
Now that we know x, we can substitute it back into the equation we found earlier:
16x + 30 = m/KAI
16(9.375) + 30 = m/KAI
150 + 30 = m/KAI
m/KAI = 180
So, we know that angle KAI measures 180 degrees. To find m/YAI, we need to subtract the measure of angle KAI from 180 degrees:
m/YAI = 180 - m/KAI
m/YAI = 180 - 180
m/YAI = 0
Therefore, we can conclude that the measure of angle YAI is 0 degrees. This means that YAI is not an angle, but a line segment, and it does not have a measure in degrees.
A certain triathlon consists of a 2.6 mile swim, a 110 mile bicycle ride, and a 26.2mile run. At one point, a participant had completed as many miles as the number of miles left to complete. How many miles had he completed at that mark?
Answer:
Let x be the number of miles completed by the participant before the mark. Then, the total distance of the triathlon is:
2.6 + 110 + 26.2 = 138.8 miles
At the mark, the participant has completed x miles and has the remaining distance to complete, which is:
138.8 - x
According to the problem, x is equal to the remaining distance:
x = 138.8 - x
Solving for x, we get:
2x = 138.8
x = 69.4
Therefore, the participant had completed 69.4 miles at the mark.
3) The Algebros go paintballing. Mr. Kelly and Mr. Sullivan climb up and lie on the top of a shed that is 5 feet off
the ground. The others send Mr. Brust up a tree to hide and he was doing a great job picking off the competition
when he stands up and shouts "Guys....Gee.... I'm a Tree!" The guys on the shed decide to just take him out so he
doesn't give away their position. They look up at about a 65° angle of elevation and know that the tree is 40 feet in
front of them. How far will Mr. Brust fall out of the tree when they shoot him?
Mr. Brust is standing at a height of approximately 90.6 feet in the tree. When they shoot him, he will fall from this height.
How to solveLet's break down the problem and solve it step by step.
First, we'll find the height from which Mr. Brust falls, and then we'll find the total distance he falls considering the tree's height and the height of the shed.
Find the height of the tree where Mr. Brust is standing:
We can use the tangent function to find the height of the tree above the shed where Mr. Brust is hiding.
tan(θ) = opposite/adjacent
We know the angle of elevation (θ) is 65°, and the tree is 40 feet in front of the shed. So, we have:
tan(65°) = height_above_shed / 40 ft
height_above_shed = 40 ft * tan(65°)
Using a calculator, we find:
height_above_shed ≈ 40 ft * 2.14 ≈ 85.6 ft
Find the total height of the tree where Mr. Brust is standing:
Since Mr. Kelly and Mr. Sullivan are 5 feet off the ground, we need to add this height to the height_above_shed we just calculated:
total_height = height_above_shed + height_of_shed
total_height = 85.6 ft + 5 ft = 90.6 ft
So, Mr. Brust is standing at a height of approximately 90.6 feet in the tree. When they shoot him, he will fall from this height.

The function S=m^(2)+6m+8 models the growth of book sales in m months, where S is an amount in thousands of dollars. In how many months do book sales reach $80,000 ?
Answer:
We are given the function S = m^2 + 6m + 8 which models the growth of book sales in m months, where S is an amount in thousands of dollars. We want to find in how many months book sales reach $80,000.
We can set up an equation as follows:
S = m^2 + 6m + 8 = 80
Subtracting 80 from both sides, we get:
m^2 + 6m - 72 = 0
We can factor this quadratic equation as:
(m + 12)(m - 6) = 0
This gives us two possible solutions:
m + 12 = 0 or m - 6 = 0
Solving for m in each case, we get:
m = -12 or m = 6
Since we are looking for a number of months, we can discard the negative solution.
Therefore, book sales reach $80,000 in 6 months.
So, the answer is: 6 months.

Compute the probability that a randomly selected person does not have a birthday on the 1st day of the month.
Answer:
0.9973 or 364/365
Step-by-step explanation:
Assuming that every day of the year is equally likely to be someone's birthday, the probability that a randomly selected person has a birthday on the 1st day of the month is 1/365, since there are 365 possible birthdays in a year.
Therefore, the probability that a randomly selected person does not have a birthday on the 1st day of the month is:
P(not on 1st day) = 1 - P(on 1st day)
P(not on 1st day) = 1 - 1/365
P(not on 1st day) = 364/365
So, the probability that a randomly selected person does not have a birthday on the 1st day of the month is 364/365 or approximately 0.9973.

Rewrite quadratic function in standard form
Since the function is already in standard form (ax^2 + bx + c form) you don't have to change anything and simply rewrite it.
For the vertex, if you have a quadratic function in standard form -b/2a is the x value of the vertex.
-b/2a = -4/(2(2)) = -1
Since we now know the x-value of the vertex we can plug it into the function to find the corresponding y-value.
h(-1) = 2(-1)^2 + 4(-1) - 10 = -12

Elmer invested $100 into a savings account that earns annual simple interest. At the end of 3 years, he earned $15 in interest. What is the interest rate on the savings account? Round to the nearest tenth of a percent.
Answer:
To find the interest rate, we can use the formula for simple interest:
I = Prt
Where:
I = Interest earned
P = Principal (initial investment)
r = Interest rate
t = Time
We are given that P = $100, t = 3 years, and I = $15. Substituting these values, we get:
15 = 100 * r * 3
Solving for r, we get:
r = 15 / (100 * 3) = 0.05

Sally opens a savings account with $9,000 that earns 7% interest per year, not compounded How much interest, to the nearest penny, will Sally earn in 7 years?
Answer: Sally will earn $4,830.00 in interest over 7 years.
Step-by-step explanation:
If the interest is not compounded, then Sally will earn simple interest, which can be calculated using the formula:
I = P * r * t
where:
I = the interest earned
P = the principal amount (initial investment)
r = the annual interest rate (as a decimal)
t = the time period, in years
In this case, we have:
P = $9,000 (the initial deposit)
r = 7% = 0.07 (the annual interest rate)
t = 7 (the number of years)
So, plugging in the values:
I = $9,000 * 0.07 * 7
I = $4,830.00
Therefore, Sally will earn $4,830.00 in interest over 7 years.

A = [-4/3 -1/3; 10 10/3] is the matrix that fulfills the equation A × [1 0; -1 3] = [-1 -3; 1 6].
What in mathematics is a matrix?Rows and sections of integers are arranged in a matrix. Learn about matrices' lengths and components as you begin your study of them. A rectangle matrix is a grouping of integers into rows as well as columns. The matrix A, for instance, has two rows along with three columns.
To find the matrix A, we need to solve the matrix equation:
A × [1 0; -1 3] = [-1 -3; 1 6]
We can do this by multiplying both sides by the inverse of [1 0; -1 3] on the left:
A × [1 0; -1 3] × [3 0; 1 1/3] = [-1 -3; 1 6] × [3 0; 1 1/3]
Simplifying the left-hand side using the associative and commutative properties of matrix multiplication, we get:
A × [3 0; -1 1] = [-3 -1; 10 3]
Now, we can solve for A by multiplying both sides by the inverse of [3 0; -1 1]:
A × [3 0; -1 1] × [1/3 0; 1/3 1] = [-3 -1; 10 3] × [1/3 0; 1/3 1]
Simplifying the left-hand side using the associative and commutative properties of matrix multiplication, we get:
A × [1 1/3; 0 1] = [-2/3 -1/3; 10/3 3]
Multiplying both sides by the inverse of [1 1/3; 0 1]:
A = [-2/3 -1/3; 10/3 3] × [1 1/3; 0 1]⁻¹
We can easily find the inverse of [1 1/3; 0 1]:
[1 1/3; 0 1]⁻¹ = [1 -1/3; 0 1]
So, substituting this into the equation for A, we get:
A = [-2/3 -1/3; 10/3 3] × [1 -1/3; 0 1]
Multiplying the matrices on the right-hand side, we get:
A = [-2/3 -1/3; 10/3 3] × [1 -1/3; 0 1] = [-4/3 -1/3; 10 10/3]
Therefore, the matrix A that satisfies the equation A × [1 0; -1 3] = [-1 -3; 1 6] is:
A = [-4/3 -1/3; 10 10/3]

Suppose 50 rabbits are on Groff Farm… DOUBLING every year…
How many rabbits after 5 years?
How many rabbits after 10 years?
Answer:
Step-by-step explanation:
After the first year, the number of rabbits will double from 50 to 100.
After the second year, the number of rabbits will double again from 100 to 200.
This doubling process will continue for a total of 5 years, so after 5 years, the number of rabbits will be:
Number of rabbits after 5 years = 50 x 2^5 = 50 x 32 = 1600
Therefore, there will be 1600 rabbits on Groff Farm after 5 years.
Similarly, after 10 years, the number of rabbits will double 10 times:
Number of rabbits after 10 years = 50 x 2^10 = 50 x 1024 = 51200
Therefore, there will be 51,200 rabbits on Groff Farm after 10 years.

What is the function’s average rate of change from x=-1 to x=1
Answer:
The average rate of change of the function from x=-1 to x=1 is 6.
Step-by-step explanation:
The average rate of change of a function from x=-1 to x=1 is the change in the output of the function (y-value) divided by the change in the input of the function (x-value). In other words, it is the slope of the line connecting the two points (x=-1 and x=1).
What is an undefined slope
Answer: The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

32.0π cm²
83.2π cm²
91.2π cm²
115.2π cm²
Answer:
D) 115.2π cm².
Step-by-step explanation:
The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πr² + 2πrh
where r is the radius and h is the height of the cylinder.
In this case, r = 4 cm and h = 10.4 cm. Substituting these values in the formula, we get:
Surface Area = 2π(4)² + 2π(4)(10.4)
Surface Area = 2π(16) + 2π(41.6)
Surface Area = 32π + 83.2π
Surface Area = 115.2π
Therefore, the exact surface area of the candle is 115.2π cm².
The answer is (D) 115.2π cm².
Answer: The answer is D, 115.2π cm²
Step-by-step explanation: When we use the formula of 2πrh+2πr2=2·π·4·10.4+2·π·42 to get the surface area, which equals 361.91
