The sum of the three angles is 180. One is given and the other we can figure out because it forms a straight line (180) with the angle to the left outside. The outside angle is 117, so 180-117 is 63.
So then add up the 3 angles in the triangle
63+35+y=180
y= 82

The measure of angle MTU m∠MTU is 114 degree.
What is the measure of angle MTU?From the figure in the diagram:
Measure of angle STU is 145 degrees and measure of angle STM is 31 degree.
m∠STU = 145°m∠STM = 31°m∠MTU = ?Since, angle STU composes or is the sum of angle STM and angle MTU.
To find angle MTU, simply subract angle STM from angle STU.
m∠STU = m∠STM + m∠MTU
Hence:
m∠MTU = m∠STU - m∠STM
Plug in the given values and simplify
m∠MTU = 145° - 31°
Subtract 31 from 145
m∠MTU = 114°
Therefore, angle MTU measure 114°.

What is a piecewise-defined function?In Mathematics, a piecewise-defined function refers to a type of function that is defined by two or more mathematical expressions over a particular domain.
Generally speaking, the domain of any piecewise-defined function simply refers to the union of all of its sub-domains.
When the domain is -2 < x ≤ -1, the rule for the piecewise-defined function f(x) is given by:
f(x) = -3
When the domain is -1 ≤ x ≤ 0, the rule for the piecewise-defined function f(x) is given by:
f(x) = -2
When the domain is 0 ≤ x ≤ 1, the rule for the piecewise-defined function f(x) is given by:
f(x) = -1
In conclusion, we can reasonably infer and logically deduce that all of the y-values of this piecewise-defined function are located on the negative y-coordinate based on the domain.

Prove the identity with rules
(1-cos(-x)) / (sec(-x)-1) =cosx
Answers
By using the rules:
\(cos(-x) = cos(x)\\\\sec(x) = \frac{1}{cos(x)}\)
We have proven the identity. Below you can follow the demonstration.
How to prove the identity?Here you need to remember two things:
\(cos(-x) = cos(x)\\\\sec(x) = \frac{1}{cos(x)}\)
Here we have the expression:
\(\frac{1 - cos(-x)}{sec(-x) - 1}\)
By using the first rule, we can rewrite:
\(\frac{1 - cos(-x)}{sec(-x) - 1} = \frac{1 - cos(x)}{sec(x) - 1}\)
By using the second rule, we can rewrite:
\(\frac{1 - cos(x)}{sec(x) - 1} = \frac{1 - cos(x)}{\frac{1}{cos(x)} - 1}\)
Now if we multiply and divide by cos(x), we get:
\(\frac{1 - cos(x)}{\frac{1}{cos(x)} - 1} = \frac{1 - cos(x)}{\frac{1}{cos(x)} - 1} *\frac{cos(x)}{cos(x) } = \frac{(1- cos(x))*cos(x)}{1 - cos(x)} = cos(x)\)
In this way, the identity was proven.

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?
Answers
Answer:
Mei descends faster
Mei's height decreases 5ft every second
Victor's height decreases 3.33 ft every second
Step-by-step explanation:
Given
Mel
\((x_1,y_1) = (2,50)\)
\((x_2,y_2) = (5,35)\)
Victor
\((x_1,y_1) = (1,60)\)
\((x_2,y_2) = (4,50)\)
Required
Who descend faster?
To do this, we simply calculate the slope/rate of both individuals
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
For Mei:
\(m_1 = \frac{y_2 - y_1}{x_2 - x_1}\)
\((x_1,y_1) = (2,50)\)
\((x_2,y_2) = (5,35)\)
\(m_1 = \frac{35 -50}{5 - 2}\)
\(m_1 = \frac{-15}{3}\)
\(m_1 = -5\)
Mei descends at 5ft per second
For Victor:
\(m_2 = \frac{y_2 - y_1}{x_2 - x_1}\)
\((x_1,y_1) = (1,60)\)
\((x_2,y_2) = (4,50)\)
\(m_2 = \frac{50-60}{4 - 1}\)
\(m_2 = \frac{-10}{3}\)
\(m_2 = -3.33\)
Victor descends at 3.33ft per second
By comparison:
Mei descends faster

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 103°, a = 12 cm, c = 22 cm (5 points) a 128.62 cm2 b 132 cm2 c 29.69 cm2 d 257.23 cm2
Answers
The area of the triangle, Rounded to the nearest hundredth, is approximately 132.02 cm².
The area of a triangle with the given measurements, we can use the formula for the area of a triangle using side lengths and an included angle. The formula is:
Area = (1/2) * a * c * sin(B)
where a and c are the side lengths, B is the included angle between those sides, and sin(B) represents the sine of angle B.
Let's calculate the area using the given measurements:
B = 103° (included angle)
a = 12 cm
c = 22 cm
First, we need to convert the angle from degrees to radians, as the sine function operates on radians. We can use the conversion: radians = degrees * (π/180).
B in radians = 103° * (π/180) ≈ 1.8 radians
Next, we can substitute the values into the formula:
Area = (1/2) * a * c * sin(B)
= (1/2) * 12 cm * 22 cm * sin(1.8 radians)
Using a calculator, we can evaluate sin(1.8 radians) ≈ 0.9833.
Area ≈ (1/2) * 12 cm * 22 cm * 0.9833
≈ 132.02 cm² (rounded to the nearest hundredth)
Therefore, the area of the triangle, rounded to the nearest hundredth, is approximately 132.02 cm².
Among the given options, the closest match is:
b) 132 cm² (rounded to the nearest whole number)

Suppose that you deposit $6500 into a bank account that pays 4% annual interest compounded continuously. Assuming that you make no other deposits or withdrawals, how long will it take before your account balance reaches $10,000?
Round your answer to the nearest tenth.
Answers
The time it will take for your account balance to reach $10,000 is given as follows:
t = 10.8 years.
What is continuous compounding?The balance of an account after t years, using continuous compounding, is given as follows:
A(t) = A(0)e^(kt).
In which:
A(0) is the initial deposit.k is the interest rate, as a decimal.The parameters for this problem are given as follows:
A(0) = 6500, k = 0.04.
Hence the time needed for a balance of $10,000 is obtained as follows:
10000 = 6500e^(0.04t)
e^(0.04t) = 10000/6500
0.04t = ln(10000/6500) -> ln is the inverse operation of the exponential
t = ln(10000/6500)/0.04

Approximately 99.7% of scores lie in the shaded region.
We have,
The empirical rule, also known as the 68-95-99.7 rule, provides an estimate of the percentage of scores that lie within a certain number of standard deviations from the mean in a normal distribution.
According to this rule:
Approximately 68% of scores lie within 1 standard deviation of the mean.
Approximately 95% of scores lie within 2 standard deviations of the mean.
Approximately 99.7% of scores lie within 3 standard deviations of the mean.
Now,
In the given scenario, the shaded region represents the area between -2 and 3 standard deviations from the mean on the x-axis.
This encompasses the area within 3 standard deviations of the mean.
And,
Since 99.7% of scores lie within 3 standard deviations of the mean, we can estimate that approximately 99.7% of scores lie in the shaded region.
Therefore,
Approximately 99.7% of scores lie in the shaded region.
