There is no slope, hence the equation of the line will be in the form y = b. Then the equation of the line that is perpendicular to the given line and passes through the point (1, 5) exists (A) y = 5.
What is meant by equation?The definition of an equation in algebra exists as a mathematical statement that demonstrates the equality of two mathematical expressions.The equation of a perpendicular line to a line in point-slope form is expressed as:
y - y1 = -1/m(x - x1)m is the slope(x1, y1) is any point on the lineDetermine the slope:
Slope = -3-3/2-2y = ∞Since there is no slope, hence the equation of the line will be in the form y = b.
Where b exists the y-coordinate of the point. Hence the required equation of the line is y = 5Therefore, there is no slope, hence the equation of the line will be in the form y = b. Then the equation of the line that is perpendicular to the given line and passes through the point (1, 5) exists (A) y = 5.

Jenna bought a new car for $29,000. She paid a 10% down payment and financed
the remaining balance for 48 months with an APR of 4.5%. Determine the monthly
payment that Jenna pays.
If the remaining balance for 48 months with an APR of 4.5%. the monthly payment that Jenna pays is: $595.17.
How to find the monthly payment?Using this formula to determine the monthly payment
P = A ×r × ( 1 +r)^n ÷( 1+ r)^n -1
Where:
P = Principal = ?
A = Amount = $29,000 × ( 1- .10) = 26,100
r = Interest rate = 4.5% / 12 = 0.00375
n = number of months = 48 months
Let plug in the formula
P = 26,100 × 0.00375 × ( 1+ 0.00375)^ 48 ÷ ( 1+ 0.00375)^ 48 -1
P = 26,100 × 0.00375 × ( 1.00375)^ 48 ÷ ( 1.00375)^ 48 -1
P = 26,100 × 0.00375 × 1.196814377 ÷ 1.196814377 -1
P = 26,100 × 0.00375 × 1.196814377 ÷ 0.196814377
P = $117.1382456 ÷ 0.196814377
P = $595.17
Therefore $595.17 is the monthly payment.

a₉₀ = 168
Step-by-step explanation:
there is a common difference between consecutive terms, that is

this indicates the sequence is arithmetic with nth term

the population average cholesterol content of a certain brand of egg is 215 milligrams, and the standard deviation is 15 milligrams. assume the variable is normally distributed. (a) find the probability the cholesterol content for a single egg is between 210 and 220. (b) find the probability the average cholesterol content for 25 eggs is between 210 and 220. (c) find the third quartile for the average cholesterol content for 25 eggs. (d) if we are told the average for 25 eggs is less than 220 mg, what is the probability the average is less than 210 mg?
Using the normal distribution, the probabilities are given as follows:
a) Between 210 and 220 for a single egg: 0.2586 = 25.86%.
b) Between 210 and 220 for the average of 25 eggs: 0.8164 = 81.64%.
c) Third quartile for the average of 25 eggs: 213 milligrams.
d) Less than 220 if less than 210: 0.1011 = 10.11%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The mean and the standard deviation for the cholesterol levels are given as follows:
[tex]\mu = 215, \sigma = 15[/tex]
For item a, the probability is the p-value of Z when X = 220 subtracted by the p-value of Z when X = 210, hence:
X = 220:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (220 - 215)/15
Z = 0.33
Z = 0.33 has a p-value of 0.6293.
X = 210:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (210- 215)/15
Z = -0.33
Z = -0.33 has a p-value of 0.3707.
Hence the probability is:
0.6293 - 0.3707 = 0.2586.
For item b, we are dealing with a sample of 25, hence we apply the Central Limit Theorem as follows:
n = 25, s = 15/sqrt(25) = 3.
X = 220:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (220 - 215)/3
Z = 1.33
Z = 1.33 has a p-value of 0.9082.
X = 210:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (210 - 215)/15
Z = -1.33
Z = -1.33 has a p-value of 0.0918.
Then the probability is:
0.9082 - 0.0918 = 0.8164 = 81.64%.
The third quartile is X when Z has a p-value of 0.25, so X when Z = -0.675, hence:
[tex]Z = \frac{X - \mu}{s}[/tex]
-0.675 = (X - 215)/3
X - 215 = -0.675 x 3
X = 213.
The conditional probability in item d is calculated as follows:
P(X < 210)/P(X < 220) = 0.0918/0.9082 = 0.1011 = 10.11%.

It is given that lines k and p are parallel. You also know that angles 2 and 3 are equal because of vertical angles. Due to the parallel lines, you can say that angles 1 and 2 are equal because they are corresponding angles (same-side).
These two angles are not alternate interior angles because angle 1 is exterior and on the same side as angle 2. The third option would not make sense because you are trying to prove two angles are equal, not that lines are parallel.

The two linear equations are perpendicular.
What are the lines?
Here we have the two linear equations:
12y - 4x = 84
y = -3x + 8
If we write both of them in the slope-intercept form (as the second one) we will get:
12y - 4x = 84
12y = 4x + 84
y = (4x + 84)/12
y = (1/3)*x + 7
Now, if we take the product of the slopes of the two lines, we get:
p = -3*(1/3) = -1
when this product is -1, the lines are perpendicular, so that is the relation between our lines.

what percentage grade should a road have if the angle of elevation of the road is 44 degrees? (the percentage grade is defined as the change in the altitude of the road over a 100100 -foot horizontal distance. for example a 5%5% grade means that the road rises 55 feet for every 100100 feet of horizontal distance.)
For a 44° elevation angle, the grade will be 96%.
Given that,
if the angle of elevation of the road is 44 degrees,
The difference in the road's altitude over a horizontal distance of 100 feet is what is referred to as the percentage grade. For instance, a road with a 5% slope will rise 5 feet for every horizontal 100-foot distance.)

The tangent of the angle is the ratio of rise to run.

The rate of the slowest car is 86 km/hr using the concept of relative velocity.
What is Relative velocity?Relative speed is the rate at which one moving body moves in relation to another. The differential between two moving bodies determines their relative speed while they are traveling in the same direction. However, when two bodies are traveling in opposition to one another, the relative speed is determined by averaging their respective speed.
Let the speed of 1st car is v₁.
Let the speed of 2nd car is v₂.
v₁- v₂ = 18 km/hr --- (1)
And using the concept of relativity.
S(rel) = D(rel)/time

Answer:
Let's break down the given information.
Car A
Speed - 30 mph
Hence the distance traveled per minute would 30/60 mph which is 0.5 Miles every minute.
Car B
Speed - 36 mph
The distance traveled per minute would 36/60 mph which is 0.6 Miles every minute.
Initial distance between the cars is 10 Miles
Car A travels 1 miles in 2 minutes and Car B travels 1.2 miles in 2 minutes.

A bag contains:• 3 red marbles• 2 2 orange marbles• 1 yellow marble• 4 green marblesA marble is drawn from the bag and replaced 150times. How many times can you predict that a greenmarble or yellow marble will be drawn?
The probability of getting a green of a yellow marble can be determined like this:
Probability = (yellow marbles + green marbles) / total number of marbles
Probability = (1 + 4) / 10
Probability = 5 / 10
Probability = 1/2
By multiplying the given probability by the number of times a marble will be drawn, we get how many times we can predict that a green or a yellow marble will be picked, then we get:
Number of predictions = 150 × 1/2
Number of predictions = 75
Then, the answer is 75 times
Answer:
75 times.
Step-by-step explanation:
There are a total of 10 marbles in the bag.
Probability a green marble is drawn (in 1 draw) = 4/10 = 2/5.
In 150 draws you can expect to draw 150* 2/5 = 60 green marbles.
Probability a yellow marble is drawn (in 1 draw) = 1/10.
In 150 draws you can expect to draw 150* 1/10 = 15 yellow marbles.
So, the number of times for a green or yellow marble

hi I circled the answer but I just need to figure out how to do it
Let's begin by listing out the information given to us:
216^(-2n) = (1/6)^(3n+2)
6 is a factor of 216: 216 = 6³
1/6 = 6^(-1)
⇒ 6^(-2*3n) = 6^[(-1*(3n+2)]
⇒ 6^(-6n) = 6^(-3n-2)
Since both sides are in the same base, we equate the exponents. We have:
-6n = -3n - 2
Add "6n" from both sides, we have:
-6n + 6n = -3n + 6n - 2 ⇒ 0 = 3n - 2
⇒ 3n = 2
