The values of the angles m∠1 and m∠3 is equal to 73°.
A transversal may be defined as a line which cuts a pair of parallel lines and forms several angles. When transversal cuts parallel lines the alternate interior angles are equal as well as the corresponding angles are equal. Also, the pair of vertically opposite angles are equal. From the figure attached. ∠4 = ∠8 as they are corresponding angles. So, m∠8 = m∠4 = 107°. Now, we know that ∠1 and ∠4 formed a pair of linear angles and the sum of the measures of the linear angles is 180°. So,
m∠1 + m∠4 = 180°
We know, m∠4 = 107°
m∠1 = 180° - 107°
m∠1 = 73°
Now, ∠1 and ∠3 are vertically opposite angles, so they are equal as the parallel lines are cut by transversal. Therefore, m∠1 = m∠3
=> m∠1 = 73°
=> m∠3 = 73°

MEAN The mean A of two numbers, x and y, is given by A =*+. Solve for y.
The mean can be written as mean A= x+ y/2
What is Mean?A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.
Only numerical variables—regardless of whether they are discrete or continuous—can be used to determine the mean. Simply dividing the total number of values in a data set by the sum of all of the values yields it.
The mean formula is

A car’s velocity increases from 4.2m/s to 14.8 m/s, E, in 2.5 sec. What is its acceleration?
The acceleration is 4.24 m^2/s
What is acceleration?
They are accelerations and vector quantities. The direction of an object's acceleration is determined by the direction of the net force acting on it. Acceleration describes the rate at which a speed changes over time.
The velocity is changing over time. The velocity is actually changing at a constant rate of 10 m/s per second. If an object's velocity is changing, it is said to be accelerating; it has acceleration.
According to question,
Acceleration = final velocity- initial velocity/ time
Final velocity = 14.8 and initial velocity = 4.2
Hence, acceleration = 14.8-4.2/2.5
=10.6/2.5

Calculate the average rate of change of fover the interval -3≤x≤9. Show the calculations that lead to your answer.
The function has an average rate of change f is 1/2 over the interval
How to determine the average rate of change f?The possible graph that completes the question is added as an attachment
The interval is given as
-3 ≤ x ≤ 9
This can be rewritten as
x = -3 to x = 9
This can also be represented as
(a, b) = [-3, 9]
From the attached graph, we have
f(-3) = -1.5
Also, we have
f(9) = 0.5
The estimate (to one decimal place) of the average rate of change f is calculated as
Rate = [f(b) - f(a)]/[b - a]
This gives
Rate = [f(9) - f(-3)]/[9 + 3]
So, we have
Rate = [0.5 + 1.5]/[9 + 3]
Evaluate
Rate = 2/12
Simplify
Rate = 1/6
Hence, the average rate of change f is 1/6

Using addition of polynomials, the function modeling the number of people attending degree-granting institutions is:
P(t) = 48.7t² + 678.5t + 17667.4.
What is the function for the total number of people attending the institutions?The number of males is given by:
M(t) = 19.7t² + 310.5t + 7539.6.
The number of females is given by:
F(t) = 28t² + 368t + 10127.8.
The total number is given by the addition of the number of males and of females, that is:
P(t) = M(t) + F(t).
Which is an addition of polynomials. To add the polynomials, we combine the like terms, that is, adding the terms that have the same variable and exponent. Hence:
P(t) = M(t) + F(t).
P(t) = 19.7t² + 310.5t + 7539.6 + 28t² + 368t + 10127.8.
