Damien deposited $250 in an account that earned 3.75% interest compounded annually.
He did not make additional deposits or withdrawals.
What will be the balance in this account at the end of 4 years?
The balance in his account at the end of 4 years will be $289.67.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Principal amount (P) = $250
Rate (r) = 3.75%
Time (t) = 4 years
Now,
Since, We know that;
⇒ [tex]A = P (1 + \frac{r}{100} )^t[/tex]
Where, A is the future amount.
P is the principal amount.
t is the time.
r is the rate.
Thus, By substitute all the values, we get;
⇒ [tex]A = P (1 + \frac{r}{100} )^t[/tex]
⇒ A = 250 (1 + 3.75/100)⁴
⇒ A = 250 (103.75/100)⁴
⇒ A = $289.67
Thus, The balance in his account at the end of 4 years will be $289.67.

Solve using elimination. x − 8y = 19 9x + 8y = 11 (, )
Answer:
[tex](3;-2)[/tex]
Step-by-step explanation:
Let's add together the two equations
[tex]I + II : x-8y +9x +8y = 19+11 \rightarrow 10x=30 \rightarrow x =3[/tex]
At this point I would recommend simply using the value of x in the firs equation to find y. [tex]3-8y=19 \rightarrow -8y=16 \rightarrow y=-2[/tex]
Or just multiply the first by 9 and subtract the second.
[tex]9\times I-II: 9x-72y-9x-8y=171-11 \rightarrow -80y=160 y=-2[/tex]
Simplify the following expression \sqrt(75)+\sqrt(108)=a\sqrt(b) If the expression is simplified completely, what does a equal and what does b equal
[tex] \sqrt{75} + \sqrt{108} = a \sqrt{b} [/tex]
[tex] \sqrt{75} = \sqrt{3 \times 5 {}^{2} } = 5 \sqrt{3} [/tex]
[tex] \sqrt{108} = \sqrt{2 {}^{2} + 3 {}^{3} } = 2 \times 3 \sqrt{3} = 6 \sqrt{3} [/tex]
[tex] \sqrt{75} + \sqrt{108} = 5\sqrt{3} + 6 \sqrt{3} = 11 \sqrt{3} [/tex]

Tasha is a single taxpayer. She has $90,000 in ordinary taxable income and $12,000 in capital gains on an investment she held for six years. Use the tables to complete the statement.

Answer: 15%
Step-by-step explanation:
I hope this helps,
have an wonderful Day!
The tax rate Tasha will pay on her investment income is 15%.
How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
We are given that;
Ordinary taxable income= $90,000
Capital gains= $12,000
Now,
The tax rate Tasha will pay on her investment income depends on her ordinary taxable income and the tax brackets for qualified dividends and long-term capital gains. Since Tasha’s ordinary taxable income is $90,000, she falls in the 15% tax bracket for her investment income.
Therefore, by the percentage the answer will be 15%.

-20 divided 2+ (-15)=
Answer:
-35
Step-by-step explanation:
Using the rules of BIMDAS, division goes before addition, hence -20/2 which gives you -10
Put that in the equation and it would be:
-10 + (-15)
A negative and a positive make a negative hence, you could simply write it as:
-10 - 15
Which equals -35
Which equation for g(x) represents the transformation of f(x) given that f(x) = x^2
g(x) = f(x) shifted left 2 units?
PLEASE HELPPP
Lets shift
[tex]\\ \rm\Rrightarrow f(x)=x^2[/tex]
[tex]\\ \rm\Rrightarrow g(x)=(x+2)^2[/tex]
[tex]\\ \rm\Rrightarrow g(x)=x^2+2x+4[/tex]
Answer:
g(x) = (x + 2)²
Step-by-step explanation:
In function notation, if we want to shift a function to the left, we add the number we are asked to move to the left inside the function's argument:
⇒ To shift f(x) b units to left → f(x + b)
Similarly, if we want to shift a function to the right, we subtract the number we are asked to move to the right inside the function's argument:
⇒ To shift f(x) b units to right → f(x - b)
Given function f(x) = x²
Shift 2 units to the left: f(x + 2) = (x + 2)²
Therefore, g(x) = (x + 2)²
i need help with this please!
Answer:
Plug in those values for the x in the equations.
Step-by-step explanation:
f(x) = x^2 + x
(x = -1) :: f(-1) = (-1)^2 + (-1)
f(-1) = -1 + -1
f(-1) = -2
(x = 2) :: f(2) = (2)^2 + (2)
f(2) = 4 + 2
f(2) = 6
f(x) = x^2 - x
(x = -1) :: f(-1) = (-1)^2 - (-1)
f(-1) = 1 - (-1)
f(-1) = 2
(x = 2) :: f(2) = (2)^2 - (2)
f(2) = 4 - 2
f(2) = 2
f(x) = -x^2 - x
(x = -1) :: f(-1) = -(-1)^2 - (-1)
f(-1) = -1 + 1
f(-1) = 0
(x = 2) :: f(2) = -(2)^2 - (2)
f(2) = -4 - 2
f(2) = -6

Lorena is designing a rectangular patio in her garden. She has enough tiles to cover 324 square feet. She wants the length of the patio to be 15 feet longer than the width. What dimensions should Lorena use for the patio?
Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.
What is the area of a rectangle?The area of a rectangle of length l and width w is given by:
A = lw.
In this problem:
She has enough tiles to cover 324 square feet, hence A = 324.She wants the length of the patio to be 15 feet longer than the width, hence l = 15 + w.Thus:
324 = w(15 + w)
w^2 + 15w - 324 = 0
w = -27 or w = 12.
We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.
The dimensions should be a width of 12 feet and a length of 27 feet.

We require to create 2 equations with the repeating 3 after the decimal point.
let x = 0.93333333333 ( multiply both sides by 10 and 100 )
10x = 9.3333333333 → (1)
100x = 93.333333333 → (2)
Subtract (1) from (2) , eliminating the repeating decimal
90x = 84 ( divide both sides by 90 )
x = [tex]\frac{84}{90}[/tex] = [tex]\frac{14}{15}[/tex]

what is the slope of the function represented by the table of values below
Answer:
The correct option is A....
Step-by-step explanation:
We have a table of x,y pairs. To compute the slope we can use any two pairs, say the first two, and plug them into our formula:
m = y2-y1 / x2-x1
m = 5-13/ 0-(-2)
m = -8/0+2
m = -8/2
m = -4
We can check this answer by using a different pair: Take the last two pairs.
m = -27-(-15)/ 8-5
m = -27+15/3
m = -12/3
m = -4
Thus the slope is -4

Answer: Axis of Symmetry at x=1
Step-by-step explanation:
Internet Definition: The axis of symmetry is the vertical line that goes through the vertex of a parabola so the left and right sides of the parabola are symmetric. To simplify, this line splits the graph of a quadratic equation into two mirror images.
So pretty much you see the "hill shape" on the graph... the highest part of the hill is the axis of symmetry so the axis of symmetry is at x=1
