PLEASE WILL MARK BRAINIEST!!!!!! Jameson and Quincy each deposit $7,000 into accounts that earn 6% interest, but Jameson earns annual simple interest while Quincy earns annual compound interest. Assuming neither one of them makes any deposits or withdrawals for 5 years, which of the following is a true statement?
Jameson will have about $9,367.58 less in his account than Quincy.
Jameson will have about $267.58 less in his account than Quincy.
Jameson will have about $2,367.58 more in his account than Quincy.
Jameson will have about $2,100 more in his account than Quincy.
Jameson will have about $267.58 less in his account than Quincy.
What is Compound Interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Here, Jameson deposit Principal = $ 7000
Duration = 5 years
Rate of interest = 6 % SI per annum.
For simple Interest, Amount = P(1+RT)
Total amount in Jameson at the end of 5 years = 7000 ( 1 + 0.06 X 5)
= 7000 X 1.3
= $ 9100
Quincy deposit Principal = $ 7000
Duration = 5 years
Rate of interest = 6 % CI per annum.
For Compound Interest, Amount = P(1+R)ⁿ
Total amount in Quincy at the end of 5 years = 7000 ( 1 + 0.06)⁵
= 7000 X 1.34
= $ 9367.58
Thus, Jameson will have about $267.58 less in his account than Quincy.

[tex] \binom{ \sin( \alpha) + \sin( 2alpha ) }{1 + \cos( \alpha ) + \cos(2 \alpha ) } = \tan( \alpha ) [/tex]
I see you use the TeX command "\binom" for binomial coefficient, but I think you meant to use "\frac" to write a fraction, namely,
[tex]\dfrac{\sin(\alpha)+\sin(2\alpha)}{1+\cos(\alpha)+\cos(2\alpha)}=\tan(\alpha)[/tex]
and I assume you're supposed to establish an identity.
Recall the double angle identities for cos and sin :
cos(2α) = cos²(α) - sin²(α) = 2 cos²(α) - 1
sin(2α) = 2 sin(α) cos(α)
Now expand the left side as
(sin(α) + sin(2α)) / (1 + cos(α) + cos(2α)) = (sin(α) + 2 sin(α) cos(α)) / (1 + cos(α) + 2 cos²(α) - 1)
Factor sin(α) from the numerator, and after canceling the 1s in the denominator and factor cos(α) :
… = [sin(α) (1 + 2 cos(α))] / [cos(α) (1 + 2 cos(α))]
Cancel the factors of 1 + 2 cos(α) :
… = sin(α) / cos(α)
which is equivalent to
… = tan(α)
by definition of tan.

Find the inequality represented by the graph
Answer: y<x-1
Step-by-step explanation:
So first we have to find the blue line. y=mx+b is the equation. For slope it is 0--1 which is 1 and 1-0 which is 1 so the slope is just one or x now we need to find the y intercept which is just -1. So y<(is less than)x-1! Hope this helps :)
A+5 expressed as a difference
Answer:
A-(-5) = A+5
it is the answer
Answer:
a-(-5)
Step-by-step explanation:
Since it's originally an addition question but you want to write it as a difference (subtraction) question, you would use double negative signs. Whenever there are two double negatives next to each other, it counteracts and becomes a positive sign, however you still wrote it as a subtraction question.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) left parenthesis, z, right parenthesis she can raise with 10 dark power crystals.
Answer:
So.. Liliana used 4 crystals to race 14 zombie soldiers.
14 / 4 = 3.5. She can race 3.5 zombie soldiers if she uses 1 crystal. So, all you need to do it multiply 3.5 by 10 and you end up with 35.
So, Liliana is able to race 35 zombie soldiers with 10 power crystals.

Which equation would we use to figure out this problem? Rachael
started off with $400 in her savings account in 2005. It earns 3% interest
each year. She wants to know how much money she'll have in the account
in 2022.
Answer:
She'll have $661 in the account in 2022.
Step-by-step explanation:
Compound interest:
The amount of money earned in compound interest after t years is given by the following equation:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which A(0) is the initial amount and r is the interest rate, as a decimal.
Rachael started off with $400. It earns 3% interest each year.
This means that [tex]A(0) = 400, r = 0.03[/tex]
So
[tex]A(t) = A(0)(1+r)^t[/tex]
[tex]A(t) = 400(1+0.03)^t[/tex]
[tex]A(t) = 400(1.03)^t[/tex]
She wants to know how much money she'll have in the account in 2022.
17 years after 2005, which means that this is A(17). So
[tex]A(17) = 400(1.03)^{17} = 661[/tex]
She'll have $661 in the account in 2022.
Use the information to answer the following questions.
Jocelyn and Kari’s math quiz scores are shown.
Jocelyn: 86, 87, 95, 72, 78, 80
Kari: 88, 78, 93, 81, 75, 92
Activity 1 of 2
Part A: Based on the samples, which student generally has higher quiz scores?
A.
Kari, because the mean and median of her scores is 84.5.
B.
Kari, because the range of her scores is 18.
C.
Jocelyn, because the interquartile range of her scores is 9.
D.
Jocelyn, because she had a maximum score of 95.
Activity 2 of 2
Part B: Suppose both girls got a 90% on their next math quiz. Which student will see a greater increase in her overall math grade?
A.
Jocelyn, because her grade will increase by 1 point.
B.
Kari, because her grade will increase by 0.8 points.
C.
Kari, because her grade will increase to 85.3.
D.
Jocelyn, because her grade will increase to 84.
Answer:
A
Step-by-step explanation:
Part A, A. Kari, because the mean and median of her scores is, 84.5.
Part B, Jocely will see a greater increase overall as her previous average is less.
What are mean, median, and mode?The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
From the given information, The average score of Jocelyn is,
= (86 + 87 + 95 + 72 + 78 + 80)/6.
= 83.
And Similarly, The average score Kari is,
= (88 + 78 + 93 + 81 + 75 + 91)/6.
= 84.5.
Therefore, Kari scores better overall.
If they both get 90% on their next math quiz Jocely will see a greater increase overall as her previous average is less.

5/6 minus (- 3/4)
HELP PLS
Answer:
In order to solve this problem, you have to find the lowest common denominator. Take multiples of both 6 and 4 and see which is the lowest you have in common.
4: 4, 8, 12, 16, 20
6: 6, 12, 18, 24
So 12 is the lowest common multiple....
5/6 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
3/4 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
When the denominators are the same, you can subtract the numerators. The denominator will stay 12!
