I hope it's helpful for youYou deposit $10,000 in a bank for college. The bank will give you 2.4% interest continuously. How much is in your account after 7 years? ( round to the nearest cent (2 decimal places) )
Answer:
$12089.26
Step-by-step explanation:
10,000
1.024 (100% of 10,000 + 2.4%)
1.024 * 10,000 = 10240 (1 year)
1.024 * 10240 = 10485.76 (2 years)
1.024 * 10737.42 = 10995.12 (3 years)
1.024 * 10995.12 = 11259 (4 years)
1.024 * 11259 = 11529.22 (5 years)
1.024 * 11529.22 = 11805.92 (6 years)
1.024 * 11805.92 = 12089.26 (7 years)

By checking the definitions of typical functions, we conclude that the function f(x) = 3 · 1.5ˣ is an exponential growth function. (Correct answer: D)
How to determine the nature of the function
In this question we must determine the kind of function according to its characteristics based on definitions of typical functions, which are represented below:
Quadratic
y = a · x² + b · x + c

7+8+21+33+?=an average of 17
A mean is an arithmetic average of a set of observations. The value of the unknown number is 16.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
Let the unknown number be represented by x.
As per the formula of averages, we can write,
Mean = (Sum of observations)/Number of observations
(7 + 8 + 21 + 33 + x)/5 = 17
(69 + x) / 5 = 17
Multiply both the sides of the equation by 5,
(69 + x)/5 × 5 = 17 × 5
69 + x = 85
Subtract 69 from both the sides of the equation,
69 + x - 69 = 85 - 69
x = 16
Hence, the value of the unknown number is 16.

Given, in triangle abc, a = 32, b = 21 and angle between a and b is 40 degrees. Find the value of third side c. Options :
A 15
B 17.91
C 20.87
D 21.91
The law of cosine helps us to know the third side of a triangle. The value of third side c is 20.87.
What is the Law of Cosine?The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,
[tex]c =\sqrt{a^2 + b^2 -2ab\cdot Cos\theta}[/tex]
where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
Given, in ΔABC, a = 32, b = 21 and the angle between a and b is 40°, therefore, the value of ∠C=40°.
Now, the value of the third side of the triangle using the cosine law can be written,
[tex]c=\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}\\\\c=\sqrt{32^{2}+21^{2}-2(32 \times 21)\cdot \cos 40^o}\\\\c=\sqrt{1,024+441-1,029.5637}\\\\c=20.867 \approx 20.87[/tex]
Hence, the value of third side c is 20.87.

What is z score?Simply said, a z-score, also known as a standard score, informs you of how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.
You can plot a z-score on a normal distribution curve. The range of Z-scores ranges from -3 standard deviations (which would be on the far left of the normal distribution curve) to +3 standard deviations (which would fall to the far right of the normal distribution curve). You must be aware of the mean and population standard deviation in order to use a z-score.
Given mean = x = 36.1 inches
standard deviation = σ = 0.3
sample size = n = 72
and μ = 36.1
here z = (x - μ)/(σ/[tex]n^{1/2}[/tex])
z = (36.1 - 36 )(0.3/[tex]72^{1/2}[/tex])
z = 0.1/0.0354

account with a fixed annual interest rate of
9% compounded 4 times per year.
How
long will it take for the account balance to
reach $14,382.05?
Answer:
t = 11 years
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 9/100
r = 0.09 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(14,382.05/5,403.00) / ( 4 × [ln(1 + 0.09/4)] )
t = ln(14,382.05/5,403.00) / ( 4 × [ln(1 + 0.0225)] )
t = 11 years
Summary:
The time required to get a total amount of $14,382.05 with compoundeded interest on a principal of $5,403.00 at an interest rate of 9% per year and compounded 4 times per year is 11 years.
Find the area of each triangle
Answer:
Step-by-step explanation:
There are 3 triangles in the picture: the one on the left, the one on the right, and the overall triangle. We must first find the areas of the two smaller triangles before finding the area of the whole thing.
To find the area of a triangle, you must multiply the two legs of the triangle by each other and then divide that number by 2. For the left triangle, this would be [tex](4*4)/2=8[/tex], meaning it has an area of 8 square meters. For the right triangle, this would be [tex](4*3)/2=6[/tex], meaning the triangle on the right has an area of 6 square meters.
There are multiple ways to find the area of the big triangle, since the hypotenuse of the left triangle has been rounded. One way to find the area of the big triangle,is to add the areas of the two smaller triangles: [tex]8+6=14[/tex] square meters. For a more exact answer, we would solve [tex](5.7*5)/2=14.25[/tex]sqaure meters using the legs of the big triangle.

Answer:
inequality form: x [tex]\leq[/tex] -2 or x > 3
interval notation form: (-∞,-2] ∪ (3,∞)
Step-by-step explanation:
I attached a picture that shows all the work. You begin by isolating then solving for x on both sides. Then form a solution using the information found out about x. For example, you can combine the found inequalities for x to solve that x must be GREATER than 3 while being LESS than -2. Using that you can form an line and make a line. Remember, when writing in interval notation form you always begin from the left to the right (in reference) to the number line.
