the 2 parallel lines mean that the lines are equal
SO since BD = 18, DC is also 18
How can you prove that a constructed line is parallel to a given line? assume that the transversal line is not perpendicular to the other lines?
To prove that a line is parallel to another, one usually shows that two lines cut by a transversal have either congruent corresponding angles or alternate interior angles. In the lack of perpendicular transversal or angle knowledge, projecting lines onto a new coordinate system can show matching slopes to confirm parallelism.
Explanation:In mathematics, proving that a constructed line is parallel to a given line typically involves showing that the lines do not intersect and have the same slope or use a parallel postulate. The most common method is taking two lines l and m and a transversal t. If the corresponding angles or alternate interior angles created by t are congruent, then l and m are parallel.
For example: If line l and line m are cut by a transversal t and the corresponding angles (∠1 and ∠2) are congruent, then lines l and m are parallel. The same can be said if the alternate interior angles are congruent.
In some cases, if the transversal line is not perpendicular and we do not know about corresponding or alternate interior angles, we can establish a different coordinate system, project the lines onto the x-axis and y-axis, and show that they have the same slope which proves them to be parallel.

The function H(t) = −16t2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds. Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points) Part B: Explain what the solution from Part A means in the context of the problem. (4 points) (10 points)
We are given the functions:
h(t) = -16t^2 + 60t + 95
g(t) = 20 + 38.7t
Part A. All we have to do is to plug in the value of t = 1 to 4 on the two functions
t h(t) g(t)
1 139 58.7
2 151 97.4
3 131 136.1
4 79 174.8
Looking at
the table, we can say that the time when h(t)=g(t) must be between t=2 and t= 3
seconds
At t=2 seconds h(t) is above g(t), and at t = 3 seconds h(t) is below g(t).
Therefore the two functions must be at the same height in between.
Part B. The solution in Part A gives us the exact time where the two objects have the same height. Further, we can see from the table that h(t) is decreasing meaning the projectile is going down while g(t) is increasing so the other projectile is going up.
All I know is it's not B.
The area of a rectangle is 65 m2 , and the length of the rectangle is 3 m less than twice the width. find the dimensions of the rectangle.
The dimensions of the rectangle are 10 meters and 6.5 meters
Let the width of the rectangle be represented by w.
The length of the rectangle will then be:
= 2w - 3
Area of the rectangle = 65m²
Note that length × width = Area
Therefore, w × (2w - 3) = 65
2w² - 3w = 65
2w² - 3w - 65 = 0
2w² - 13w + 10w - 65 = 0
2w(w - 6.5) + 10(w - 6.5) = 0
Therefore, w - 6.5 = 0
w = 0 + 6.5
w = 6.5
Width = 6.5 meters
Length = 2w - 3
Length = 2(6.5) - 3
Length = 13 - 3
Length = 10 meters.
The dimensions of the rectangle is 10 meters and 6.5 meters

What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We are given that;
5x + 7 and 6x -1
Now,
The equation is:
5x + 7 = 6x - 1
To solve for x, we need to isolate x on one side of the equation. We can do this by subtracting 5x from both sides and adding 1 to both sides. This gives us:
5x + 7 - 5x = 6x - 1 - 5x
7 + 1 = x - 1 + 1
8 = x
Therefore, by the given equations the answer will be x = 8.

$1,100 at 8%, for 15 years, compounded annually. Total Amount = $ Interest Amount = $
Final answer:
Compound interest plays a crucial role in determining the final amount of an investment over time, showcasing the power of compounding. In this scenario, with an initial amount of $1,000, an interest rate of 10.1%, and 47 years of compounding annually, the total interest earned would be $91,045.80.
Explanation:
Compound interest is calculated on the principal amount plus the interest earned over time. In this case, with an initial amount of $1,000, an interest rate of 10.1% compounded annually, and an end amount of $92,045.80 after 47 years, compound interest plays a significant role in determining the final amount.
To calculate the total interest earned over the 47 years, you subtract the initial principal amount of $1,000 from the end amount of $92,045.80. This gives you the total interest earned. In this scenario, the total interest earned would be $92,045.80 - $1,000 = $91,045.80.
Compound interest is crucial in understanding how investments grow over time, and it showcases the power of compounding when money is invested wisely and for a long period.

What is the rule for the sequence with the first four terms below? 0.5, 0.25, 0, –0.25
The rule for the given sequence (0.5, 0.25, 0, -0.25) is to subtract 0.25 from the previous term. Each consecutive term decreases by 0.25 to form the sequence.
The sequence given is 0.5, 0.25, 0, -0.25. To find the rule of this sequence, look at the differences between terms. Each term is subtracted by 0.25 to get to the next term.
Step-by-Step Explanation:
Start with the first term which is 0.5.Subtracting 0.25 from the first term gives the second term, 0.25.Continuing this pattern, subtracting 0.25 from the second term gives the third term, which is 0.Finally, subtracting 0.25 from the third term gives the fourth term, which is -0.25.Therefore, the rule for this sequence is subtracting 0.25 from the previous term to obtain the next term in the sequence.

A bat flies at an average speed of 32 kilometres an hour. At this speed, how far will it fly in 15 minutes?
Final answer:
To find out the distance a bat will fly in 15 minutes at an average speed of 32 kilometers per hour, you multiply the speed by the time in hours (15 minutes is 0.25 hours). The bat will fly 8 kilometers.
Explanation:
To calculate how far a bat flies in 15 minutes at an average speed of 32 kilometers per hour, we need to convert the time into hours since the speed is given in kilometers per hour (km/h). 15 minutes is equal to 0.25 hours (since there are 60 minutes in 1 hour, so 15 minutes divided by 60 minutes per hour equals 0.25 hours).
We can then use the formula for distance which is:
Distance = Speed × Time
The average speed of the bat is 32 km/h, and the time is 0.25 hours.
Distance = 32 km/h × 0.25 h = 8 km
So, the bat will fly 8 kilometers in 15 minutes.
