4. A deposit of $4000 is made into a savings account that pays 2. 48% annual interest rate compounded quarterly.
A = P(1 + 3)"
A - amount in account
P = principal invested
r = annual interest rate
n = number of times per year that interest is compounded
t = number of year
How much money will be in the account after three years?
The total amount accrued, principal plus interest, with compound interest on a principal of $4,000.00 at a rate of 2.48% per year compounded 4 times per year over 1 years is $4,100.13.
Compound interest CalculationGiven Data
Principal p= $4000Rate r = 2.48%Time = 1 yearA = P + I where
P (principal) = $4,000.00
I (interest) = $100.13
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.48/100
r = 0.0248 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 4,000.00(1 + 0.0248/4)^(4)(1)
A = 4,000.00(1 + 0.0062)^(4)
A = $4,100.13

Marlena solved the equation 2x + 5 = –10 – x. Her steps are shown below.
2x + 5 = –10 – x
3x + 5 = –10
3x = –15
x = –5
Answer:We are asked to evaluate Marlena's solution in solving the expression below: 2x+5 = -10 -x
The first step is to re-write the expression and transpose same terms in the left side while all numbers are transferred to the right side such as shown below:
Step 0: 2x+5 = -10 -x
Step 1: 2x + x = -10 -5

Answer:
10n^2 + 2n + 16
Step-by-step explanation:
Rectangles have the same length and same width. So we can deduce that the top side is 5n^2 - 1, and the left side is n + 9.
Now all we need to do is add all 4 sides up:
(5n^2 - 1) + (5n^2 - 1) + (n + 9) + (n + 9)
or
2(5n^2 - 1) + 2(n + 9)
= 10n^2 - 2 + 2n + 18
= 10n^2 + 2n + 16

Solve for x in the circle below. Show your work, equations, and mark your answer.
Answer:
x = -8
Step-by-step explanation:
The sum of arcs of a semicircle is 180°. That means the arc whose measure is -11x+12 has a measure of 180° -80° = 100°.
-11x +12 = 100
-11x = 88 . . . . . . subtract 12

The speed limit on a road is 45 mph. you want to clock the speed of a random sample of cars to test the hypothesis that the average speed of cars is greater than the speed limit. what kind of test would you use?
The test that we would use to test the hypothesis that the average speed of cars is greater than the speed limit is: One sample t-test
When do we use one sample t-test?When we want to find out from the sample if the unknown population mean is different from some specific value, then we can use one sample t-test.
The test statistic is:
[tex]t = \dfrac{\overline{x} - \mu_0}{s/\sqrt{n}}[/tex]
where we have:
[tex]\overline{x}[/tex]= mean of the samples = sample standard deviation[tex]\mu_0[/tex] = the specific value we're comparing population mean with.n = sample sizedegree of freedom = n - 1For this case, we want to test the hypothesis that the average speed of cars is greater than the speed limit.
That means we want to know if
unknown population mean (the average speed of cars) > speed limit (45).
symbolically, we want to test if [tex]\mu > 45[/tex] (in miles per hour)
Thus, the test that we would use to test the hypothesis that the average speed of cars is greater than the speed limit is: One sample t-test

Number 7. Please asap.
7a)
[tex]\frac{n(n - 3)}{2} = 665\\n(n - 3) = 665 \cdot 2\\n(n - 3) = 1330\\n^2 - 3n = 1330\\n^2 - 3n - 1330 = 0\\n = \frac{-(-3) \pm \sqrt{(-3)^2 - 4 \cdot 1 \cdot (-1330)}}{2 \cdot 1} = \frac{3 \pm \sqrt{9 + 5320}}{2} = \frac{3 \pm \sqrt{5329}}{2} = \frac{3 \pm 73}{2}\\n_1 = \frac{3 + 73}{2} = \frac{76}{2} = 38\\n_2 = \frac{3 - 73}{2} = \frac{-70}{2} = -35[/tex]
If n is the amount of sides then there's 38 sides in a polygon with 665 diagonals
7b)
We do the same as 7a) but with 406. We get that [tex]n_1 = 30.04[/tex] and [tex]n_2 = -27.04[/tex]. A polygon cant have 30.04 sides
Answer: A. 38 sides
B. When solved, you get -27.04 sides or 30.04 sides. Neither of these are possible because the number of sides cannot be negative or a decimal.
Step-by-step explanation: Part A:
If the polygon has 665 diagonals, set your original n-sided polygon equal to it.
n(n - 3)/2 = 665
Multiply both sides by 2 so it’s not in the denominator.
n(n - 3) = 1330
Distribute n and subtract 1330 from both sides so it is equal to zero.
n² - 3n - 1330 = 0
Factor it:
(n - 38)(n * 35) = 0
Solve for n by setting it equal to zero:
n = 38 & n = -35
The number of sides cannot be negative, therefore, the answer to Part A is 38 sides.
Part B:
Set your original n-sided polygon equal to 406 and solve to prove that a polygon cannot have 406 diagonals.
n(n - 3)/2 = 406
Multiply both sides by 2 so it’s not in the denominator.
n(n - 3) = 812
Distribute n and subtract 812 from both sides so that it is equal to zero.
n² - 3n - 812 = 0
This cannot be factored, so plug it into the Quadratic Formula. Here are the values you need for the Quadratic Formula based on the polynomial above:
a = 1
b = -3
c = -812
When you solve this, you will get:
n = -27.04 and n = 30.04
A polygon cannot have negative sides and it cannot have decimal sides. It has to be a positive integer (positive whole number).
Are these equations the same ? True or false.
