An employee put $5,000 in a retirement account that offers 9% interest compounded annually. The employee makes no additional deposits or withdrawals. How much interest will the employee have earned at the end of 5 years. Make sure to round your answer to the hundredths.
Answer:
$2,693.12 will the employee have eared at the end of 5 years.
Step-by-step explanation:
The formula of compound interest:
[tex]A=P(1+r)^n[/tex]
[tex]I[/tex] = A-P
A= The amount in the account after n years
P= Principal
r= rate of interest annually
n= time in years.
An employee put $5,000 in retirement account that offer 9% interest compounded annually.
Here P=$5,000, r=9%=0.09, n= 5 years
[tex]A=5,000(1+0.09)^5[/tex]
=$7,693.12
The interest = A-P
=$(7,693.12-5,000)
=$2,693.12
$2,693.12 will the employee have eared at the end of 5 years.

Find the inner product for (8,4)(2,4)and state whether the vectors are perpendicular.
a.
8; no
c.
32; no
b.
8; yes
d.
32; yes
Please select the best answer from the choices provided
A
B
C
D
The inner product of vectors (8,4) and (2,4) is 32, and since the dot product is not zero, the vectors are not perpendicular.
The inner product (also known as the dot product) of two vectors can be calculated by multiplying the corresponding components of the vectors and then summing those products. For the vectors (8,4) and (2,4), the inner product is calculated as (8 × 2) + (4 × 4), which equals 16 + 16, and thus the inner product is 32.
To determine if the vectors are perpendicular, we need to check if their dot product is zero. In this case, since the dot product is 32, not zero, the vectors are not perpendicular to each other.
Therefore, the correct answer is C: 32; no.

What is the probability that in two rolls of a single die, a man will roll a 2 on the first roll and a number greater than five on the second?
(A) 1/3
(B) 1/6
(C) 1/12
(D) 1/18
(E) None of the above
I got; (E) None of the above. Because I got 1/36.
Is this correct?
Answer:
Step-by-step explanation:
I got A because the probability of rolling a 2 is 1/6 chance. Then the probability of getting a number greater than 5 is a 1/6 chance because there’s only one number bigger than five on a die. So I added them together got 2/6 and simplified down is 1/3
Answer:
That's right.
A 2 on the first roll means 1 possibility out of 6.
The only number greater than 5 in a dice is 6, therefore it's the same case from above.
1/6 on first roll
1/6 on second roll
[tex]\frac{1}{6} * \frac{1}{6} = \frac{1}{36}[/tex]

Answer:
3
Step-by-step explanation:
Firstly, do the numbers inside the absolute value bars.
-6-(-3)
The two negatives that are together turn to a addition sign.
-6+3
You can just subtract 6 and 3 which is 3 and add the - to it.
|-3|
The -3 turns to a 3 since the absolute value bars make all numbers positive within the bars.

The surface area of a triangular prism is 78 square inches. What is the surface area of a similar prism that is three times as large?
Answer:
234 inches
Step-by-step explanation:
The prism is 3× larger so you would multiply 78 by 3
Final answer:
To find the surface area of a similar prism three times as large, you need to square the scaling factor and multiply it by the original surface area.
Explanation:
The surface area of a triangular prism is 78 square inches. Given that the area scales in proportion to the square of the linear dimensions, if a similar prism is three times as large, the surface area of the larger prism would be 3² = 9 times the original surface area. Therefore, the surface area of the similar prism that is three times as large would be 78 square inches x 9 = 702 square inches.

Step-by-step explanation:
All of the following statements are true, except . . .
The product of b and c is positive.
The product of a and c is negative.
The product of b and 0 is 0.
The product of a and b is positive.
The only definite conclusion from the given information is that the product of b and c is positive, while the signs of a and b individually cannot be determined conclusively. Here option B is correct.
The product of a and c is negative: We cannot determine the signs of a and c individually, but from the given information, we can say that their product is negative. This is because the sum of a and c is 0 (a + b + c = 0), and b is positive.
If both a and c were positive or negative, their sum would be positive or negative, respectively. Therefore, one must be positive and the other negative for their sum to be zero.
The product of b and c is positive: As mentioned above, we know that b is positive and the product of a and c is negative. Since the sum of a, b, and c is zero, if b is positive and the product of a and c is negative, then the product of b and c must be positive to balance the equation.
The product of b and O is 0: This statement is always true because any number multiplied by zero is zero.
The product of a and b is positive: We cannot determine the signs of a and b individually based on the given information. As explained earlier, we only know that their sum is positive and the product of a and c is negative.
Therefore, the only statement that is guaranteed to be true based on the given information is that the product of b and c is positive. Here option B is correct.

Jamie paid the rent well past the due date for the months of April, May and June. As a result, he had been charged a total of $75 as late fee. How much did he pay as late fee per month?
Jamie paid $25 as a late fee per month. Hence, the final answer is $25 per month.
Explanation:To find out how much Jamie paid as a late fee per month, we first need to determine how many months he was charged for and then divide the total late fee by that number.
In this case, he was charged for the three months of April, May, and June, so there were 3 months.
The total late fee was $75, so to find out how much he paid per month, we divide the total late fee by the number of months: $75 / 3 = $25 per month.

If 2x – 3 + 3x = – 27, what is the value of x?
Answer:
x = -24/5
Step-by-step explanation:
2x – 3 + 3x = – 27
Combine like terms
5x -3 = -27
Add 3 to each side
5x-3+3 = -27+3
5x = -24
Divide each side by 5
5x/5 = -24/5
x = -24/5
Answer:
x= -24/5
Step-by-step explanation:
To solve, we need to get x by itself.
2x – 3 + 3x = – 27
Combine like terms
(2x+3x)-3= -27
5x-3=-27
Add 3 to both sides
5x-3+3=-27+3
5x= -24
Divide both sides by 5
5x/5= -24/5
x= -24/5

Answer:
x=12, both angles are 144°
Step-by-step explanation:
Since the angles are Z-angles (lookup 'alternate exterior angles') they are the same.
This means that 10x+24 = 6x+72, which can be simplified to
10-6x = 72-24
4x = 48
x = 12
Substitute x=12 in either expression and you get 144.
Given a term in a geometric sequence and the common ratio, find the explicit formula, a11=5120 ans r=-2
Answer:
[tex]U_n=5(-2)^{n-1}[/tex]
