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.

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

[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]

[tex]a = 11[/tex]

[tex]b = 3[/tex]

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

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: 15%

Step-by-step explanation:

have an wonderful Day!

The tax rate Tasha will pay on her investment income is 15%.

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%.

Answer:

5 and 3 pints

Step-by-step explanation:

there are 4 pints in 1 cup.

23 pints is equal to 46 cups using the conversion factor 2 cups = 1 pint.

As, 2 cups = 1 pint.

Using the conversion factor 2 cups = 1 pint, convert 23 pints to cups.

So, to convert pints to cups, multiply the number of pints by 2 as

= 23 pints x 2 cups/pint

= 46 cups

Therefore, 23 pints is equal to 46 cups.

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]

2: Rate of change is the comparision between the x and y values. 3: For one pound of fish, it costs $15

Step-by-step explanation:

2: For example, if you have 4y and 1x, the rate of change is 4 because rise/run, 4/1= 4

3: The cost would be y while pounds of fish would be x. so $15/1 pound = 15

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.

The area of a rectangle of length l and width w is given by:

A = lw.

In this problem:

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.

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

Answer:

[tex]\frac{14}{15}[/tex]

Step-by-step explanation:

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]
