Answer:
Yes, the side lengths
Explanation:
To be able to determine if the given side lengths of the triangle will form a right triangle, we'll have to apply the Pythagorean Theorem which states, in a right-angled triangle, the square of the hypotenuse(the longest side) must be equal to the sum of squares of the other two sides.
So let's go ahead and confirm;
[tex]\begin{gathered} 14.5^2=10.5^2+10^2 \\ 210.25=110.25+100 \\ 210.25=210.25 \end{gathered}[/tex]Since the Pythagorean theorem is obeyed as we can see above, then the side lengths will form a right triangle.

Given,
A design engineer is mapping out a new neighborhood with parallel streets. If one street passes through (4, 5) and (3, 2)
To find the equation for a passes through (2, -3).
How to determine an equation of the line parallel to another line
In this question we must derive the equation of the line for a given street and look for another equation of the line parallel to the previous one. Lines are first order polynomials of the form y = m · x + b, where m and b are the slope and the y-intercept, respectively.
Now, According to the question:
Now we present the procedure in detail. First, find the equation of the first line:
5 = 4 · m₁ + b₁ (1)
2 = 3 · m₁ + b₁ (2)
(m₁, b₁) = (3, - 7)
Second, determine the equation of the line parallel to the line found in the previous step: (Please notice that two lines are parallel to each other when they share the same slope but have different y-intercepts)
-3 = 3 · 2 + b₂
b₂ = -3 - 6
b₂ = - 9
Hence, The equation of the line parallel to the first line is y = 3 · x - 9.

By using the secant line formula, the average rate of change of function f(x) on the interval [3, 11] is equal to 4.
How to determine the average rate of change of a function
In accordance with the statement, we must determine the average rate of change for a given closed interval of the function f(x). Graphically speaking, the average rate of change for this interval is represented by the slope of the secant line passing through the two limits of the interval [a, b], which is found by secant line formula:
m = [f(b) - f(a)] / (b - a)
If we know that a = 3, f(a) = 19, b = 11 and f(b) = 51, then the average rate of change is:
m = (51 - 19) / (11 - 3)
m = 32 / 8

Benji has four -0.5 cards. what is his total score
Answers
Benji's total score is -2.
What is the total of negative numbers?If two numbers are negative, their sum will also be negative. When two negative numbers are added together, their value is further diminished, hence the sum of the two negative numbers is always negative.
Given:
Benji has four -0.5 cards.
According to the question, we have to determine his total score which will be equal to adding scores on all four cards.
As we are adding negative scores, upon adding them place a negative sign in front of the sum.
The total score of Benji = (-0.5) + (-0.5) + (-0.5) + (-0.5)
= -2
Therefore, his total score is -2.

A large tank of sterile water holds 200 gallons . It is leaking at an unknown rate. At 8:30 am the tank had 137 gallons and at 11:00 am the tank had 115 gallons. Assuming the tank was full when the leak began , write a function to estimate how much water is in the tank. now find the time at which the tank began leaking and the time at which the tank will be empty.
Answers
The time that the tank began leaking water is 12:40am
The time the tank will be empty is 11 : 23 pm.
What is the time the tank began leaking water?The function that would determine the amount of water in the tank is a linear function. A linear function is a function that has a single power that is raised to the power of one. When drawn on a graph, a linear function is a straight line.
The first step is to determine the rate of leakage of the tank.
Rate = (water in the tank at 11am - water in the tank at 8:30am) / change in time
(137 - 115) / (11 - 8:30)
22 / 2:30
22 ÷ 2 1/2 hours = 8.8 gallons per hour
Linear function would have this form:
Water in the tank = water in the tank when full - (rate of leakage x number of hours)
137 = 200 - (8.8xh)
137 = 200 - 8.8h
200 - 137 = 8.8h
63 = 8.8h
h = 63 / 8.8
h = 7.16 hours = 7 4/15 hours
8 - 7 4/15 hours = 12 10/15 hours = 12.40am
When the tank is empty:
0 = 200 - 8.8h
200 - 0 = 8.8h
200 / 8.8 = 22.72 = 22 hours 43 minutes
22 hours 43 minutes + 12 : 40M = 11 : 23 pm
