15 POINTSSS ANSWER ASAP PLEASE!!!!! What is the equation, in point-slope form, of the line that is
parallel to the given line and passes through the point (4, 1)?
y-1=-2(x - 4)
y-1=-{(x-4)
oy-1= (x-4)
y-1 = 2(x - 4)
Answers
Answer:
The Answer is : D
Step-by-step explanation:
First find the slope of the line that the equation should be parallel to. In this case it is 2/1 which simplified is 2.
Next insert the X (4) of the point (4,1) and solve to see if you get the Y(1).
y-1 = 2 (4-4)
y-1= 2 (0)
y-1= 0
y= 1
In this case D is correct.
TIP*
If you see the question ask you about a parallel formula, look at the slopes of them to see if they match up. Parallel formulas have the same slope, just a tip because you can see in the answer choices none of the equations have the same slope as the line on the graph except for D.

Find the 4th term in the sequence.
Answers
The 4th term in the sequence is -17.
To find the 4th term in the sequence defined by the recursive formula [tex]\(a(n) = a(n-1) - 5\)[/tex] with the initial condition [tex]\(a(1) = -2\)[/tex], you can use the recursive formula to compute each term. Let's find the first few terms:
1. [tex]\(a(1) = -2\)[/tex] (given)
2. [tex]\(a(2) = a(1) - 5 = -2 - 5 = -7\)[/tex] (using the recursive formula)
3. [tex]\(a(3) = a(2) - 5 = -7 - 5 = -12\)[/tex] (using the recursive formula)
4. [tex]\(a(4) = a(3) - 5 = -12 - 5 = -17\)[/tex] (using the recursive formula)
The recursive formula tells us how to calculate each term in the sequence based on the previous term. Starting with \(a(1)\), we use the formula to find [tex]\(a(2)\)[/tex], then use [tex]\(a(2)\) to find \(a(3)\)[/tex], and so on.
So, the 4th term [tex](\(a(4)\))[/tex] is found by taking the previous term [tex](\(a(3)\))[/tex], which is -12, and subtracting 5.
Complete the question:
a(1) = -2;
a(n) = a(n − 1) – 5
Find the 4th term in the sequence.
Final answer:
The 4th term in the sequence defined by a(1) = -2 and a(n) = a(n − 1) − 5 is -17, which is found by successively subtracting 5 from the previous term.
Explanation:
To find the 4th term in a sequence where a(1) = -2 and a(n) = a(n − 1) − 5, we will use the recurrence relation to determine each subsequent term:
First term (a(1)) is given as -2.The second term (a(2)) equals a(1) - 5 = -2 - 5 = -7.The third term (a(3)) equals a(2) - 5 = -7 - 5 = -12.The fourth term (a(4)) equals a(3) - 5 = -12 - 5 = -17.Therefore, the 4th term in the sequence is -17.
Jimmy's fishing boat is sailing near the shoreline when a lighthouse on the top of a 250-foot cliff is lit up. If Jimmy's sight line is 400 feet away from the lighthouse, what is the angle of depression from the lighthouse to the fishing
Answers
Answer:
32.0054
Step-by-step explanation:
i think
The angle of depression is approximately 32.01 degrees.
To find the angle of depression, we can use the concept of trigonometry. Specifically, we use the tangent function, which relates the height of the lighthouse to the distance from the lighthouse to Jimmy's boat.
Steps to solve:
Let θ be the angle of depression.The height of the lighthouse (opposite side) is 250 feet.The distance from the lighthouse to the boat (adjacent side) is 400 feet.Use the tangent function: tan(θ) = opposite / adjacent.Substitute the values: tan(θ) = 250 / 400.Simplify the fraction: tan(θ) = 0.625.Find the angle by taking the arctangent: θ = [tex]tan^{-1}[/tex](0.625).The result is approximately: θ ≈ 32.01 degrees.Therefore, the angle of depression from the lighthouse to the fishing boat is about 32.01 degrees.
Find the scale factor of the figures below from left to right given the volume of each .
Answers
Explanation:
The volumes are in the ratio 3625:783 which reduces fully to 125:27 after dividing both parts by the GCF 29.
Both 125 and 27 are perfect cubes because 125 = 5^3 and 27 = 3^3
Therefore, the volume ratio 125:27 turns to the linear scale factor ratio 5:3
If you were to cube both sides of the linear ratio 5:3, you would get the volume ratio 125:27. Cube rooting both sides will have you go in reverse.

If we add pair D (6, 5) to the table, then it stops representing a function.
What values in the table would change the relation to NOT be a function?
A relation is not a function if we can see that we have a input that is mapped into two (or more) different outputs.
Notice that in the table we already have an entry with the input x = 6, so we can't add another entry like:
(6, 5)
Because then, the table wouldn't be a function.

Step-by-step explanation:
The probability of rolling an even number and then a 3 is,
⇒ 1 / 12
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Now, the probability of rolling an even number on the first roll.
Then, There are three even numbers 2, 4, and 6 out of the 6 possible outcomes,
so the probability of rolling an even number on the first roll is,
= 3/6,
= 1/2
And, For the probability of rolling a 3 on the second roll.
There is only one outcome that will result in a 3 out of the six possible outcomes,
so the probability of rolling a 3 on the second roll is 1/6.
Now we can multiply the two probabilities together to find the probability of rolling an even number on the first roll and then a 3 on the second roll:
1/2 x 1/6 = 1/12
Hence, the probability of rolling an even number and then a 3 is,

What is the standard deviation of the data set? Round your answer to the nearest tenth.
A. 4.8
B. 4.6
C. 4.7
D. 4.3
Answers
Answer:
c. 4.7
Step-by-step explanation:
first, you find the mean of data set:
83 + 85 + 82 + 93 + 83 + 84 + 95 + 87 + 86 + 94 = 872/10 = 87.2
then, you take each number and subtract the mean and square it:
(87.2 - 83)² = (4.2)² = 17.64
(87.2 - 85)² = (2.2)² = 4.84
(87.2 - 82)² = (5.2)² = 27.04
(93 - 87.2)² = (5.8)² = 33.64
(87.2 - 83)² = (4.2)² = 17.64
(87.2 - 84)² = (3.2)² = 10.24
(95 - 87.2)² = (7.8)² = 60.84
(87.2 - 87)² = (0.2)² = 0.04
(87.2 - 86)² = (1.2)² = 1.44
(94 - 87.2)² = (6.8)² = 46.24
now, find the mean of the squared numbers:
17.64 + 4.84 + 27.04 + 33.64 + 17.64 + 10.24 + 60.84 + 0.04 + 1.44 + 46.24 = 219.6/10 = 21.96
then, take the square root of the number you just got:

A bag contains 8 red marbles, 7 blue marbles and 5 green marbles. If two marbles are drawn out of the bag, what is the exact probability that both marbles drawn will be red?
Answers
The exact probability that both marbles drawn will be red is 4/25.
Given that:
Number of red marbles in the bag, R = 8
Number of blue marbles in the bag, B = 7
Number of green marbles in the bag, G = 5
The total number of marbles in the bag is:
T = 8 + 7 + 5
= 20
The probability of drawing a colored marble is the number of marbles of that color by the total number of marbles.
So, P(R) = 8/20, P(B) = 7/20 and P(G) = 5/20
If two marbles are drawn out of the bag, the probability that both marbles are red is:
P = P(R) P(R)
= (8/20)(8/20)
= (2/5)(2/5)
= 4/25
Hence, the probability s 4/25.

Final answer:
The exact probability of drawing two red marbles from the bag without replacement is the product of the individual probabilities, calculated as (2/5) × (7/19).
Explanation:
To find the probability that both marbles drawn from a bag will be red, given the bag contains 8 red marbles, 7 blue marbles, and 5 green marbles, we need to calculate the probability of drawing one red marble and then another red marble without replacement.
The total number of marbles in the bag is 8 red + 7 blue + 5 green = 20 marbles. The probability of drawing the first red marble is 8/20, which simplifies to 2/5. After drawing one red marble, there are now 7 red marbles left and the total drops to 19 marbles. The probability of drawing a second red marble is now 7/19.
To find the probability of both events happening, we multiply the probabilities of each event: (2/5) × (7/19). Therefore, the exact probability of drawing two red marbles in succession without replacement is (2/5) × (7/19).
suppose 7,330 dollars is invested at 14.8% per annum for 10 years compounded monthly, how many dollars will be earned in interest during those 10 years, to the nearest cent
Answers
Answer:
$24,580.12
Step-by-step explanation:
Lets use the compound interest formula to solve:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, change 14.8% into a decimal:
14.8% -> [tex]\frac{14.8}{100}[/tex] -> 0.148
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
[tex]A=7,330(1+\frac{0.148}{12})^{12(10)}[/tex]
[tex]A=31,910.12[/tex]
Now subtract that number from our original amount invested:
[tex]31,910.12-7,330=24,580.12[/tex]
The dollars earned in interest is $24,580.12
