The correct option is D

The accumulated interest after 10 years is $2,125.00

Explanation:

We have the following parameters:

Principal (P) = $2,500

Rate (R) = 8.5%

Time (T) = 10 years

To calculate the interest after 10 years, we use the formula:

The interest is $2,125

A function can be written as piecewise function if it changes its behaviour ( increasing or decreasing ) about a point.

Here Here,

The given function is : y = 2|x| - 3

Here,

The function will change its behaviour when

| x | = 0

=> x = 0

Now,

If x < 0 , then ;

=> y = 2[–(x)] – 3

=> y = –2x – 3

=> y = – 2x – 3

If x ≥ 0 , then ;

=> y = 2(x) – 3

=> y = 2x – 3

=> y = 2x -3

Hence ,

y = – 2x – 3 , if x < 0

y = 2x - 3 , if x ≥ 0

Answer: [tex]4m^{6}[/tex]

Step-by-step explanation:

[tex]\frac{8.4m^{9} n^{5} }{2.1m^{3}n^{5}}[/tex]

Dividing exponents is the same as subtracting the exponents, so

[tex]\frac{m^{9}}{m^{3}} =m^{9-3}=m^{6}[/tex]

[tex]\frac{n^{5}}{n^{5}} =n^{5-5}=n^{0}=1[/tex]

So now our equation looks like

[tex]\frac{8.4m^{6}}{2.1}[/tex]

Now we can divide the numbers

8.4/2.1 = 4

So your final answer is [tex]4m^{6}[/tex]

Answer:

12 1/3 + 13 1/3 + 14 1/3 = 40

Step-by-step explanation:

Here we will use algebra to find three consecutive integers whose sum is 40. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 40. Therefore, you can write the equation as follows:

Answer:

A. [tex]f(\frac{1}{2}\pi)=2[/tex]

B. [tex]x=-2\pi, -\pi, 0, \pi, 2\pi[/tex]

C. [tex][-2, 2][/tex]

Step-by-step explanation:

A:

Since we want to find: [tex]f(\frac{1}{2}\pi)[/tex], all we do is go that that x-value on the function and then go either up or down until we find where the y-value is at that x-value, because [tex]f(\frac{1}{2}\pi)[/tex] is just another way of expressing "the y-value of the function f, at [tex]x=\frac{1}{2}\pi[/tex]

In this case it turns out that the y-value is two, which you can verify by going to that x-value and finding where the y-value is at that point.

So: [tex]f(\frac{1}{2}\pi)=2[/tex]

B.

To find all the x-values such that: [tex]f(x)=0[/tex], we just need to find where the graph crosses the x-axis, also known as an x-intercept. This is because at an x-intercept, the y-value will be equal to zero.

Looking at the graph you can see that these x-intercepts occur at: [tex]x=-2\pi, -\pi, 0, \pi, 2\pi[/tex]

in general you'll notice that all the values are actually separated by a value of pi, so the general formula for a zero in this equation is likely going to be: [tex]x=\pi n\text{ where n is an integer}[/tex], since trigonometric functions are periodic, they repeat.

C.

Looking at the graph you'll notice the value is increasing, then decreasing, then increasing... and so on.

The max value it reaches is two, and the min value it reaches is negative two.

The range of a function is the y-values that the function can output, considering all the possible inputs, or the domain.

In this case no matter the input we can only output values between -2 and 2.

In this interval notation, we use brackets, since the minimum and maximum possible values are included in the range, since the function does output 2 and -2, it doesn't just "approach" it.

So we get a range of: [tex][-2, 2][/tex]

When you locate the coordinates of A it is (-4, 1)

Locate the coordinates of A', it is : (4, 5)

Let's make a conversion:

She bought about 7.39683qt

Liz bought 7.396817 quarts of orange juice for a party.

The liquid quart in the United States is a measure of fluid volume equal to one-fourth of a gallon, two pints, or four cups. The liquid quart is not to be confused with the dry quart (US) or the imperial quart, which are two distinct units.

Multiply the volume by the conversion ratio to transform a liter measurement into a quart measurement.

Since each liter equals 1.056688 quarts, you may use the following easy formula to convert:

quarts = liters × 1.056688

The volume in quarts is equal to the liters multiplied by 1.056688.

We have been given that Liz bought seven liters of orange juice for a party.

We have to convert 7 liters to quarts using the formula above.

7 L = (7 × 1.056688) = 7.396817 qt

Thus, she bought 7.396817 quarts of orange juice for a party.

2. Second equation:

The answers are: Option A and Option B.

The equation that represent the situation is as follows;

3x + 2y = 34

1 / 2x + 2y = 14

The two number Diego is thinking of are 8 and 5.

He is thinking of two positive numbers.

If we triple the first number and double the second number, the sum is 34.

If we take half of the first number and double the second, the sum is 14.

Therefore, the equation that can be used to solve the situation is as follows:

let

x = first number

y = second number

3x + 2y = 34

1 / 2x + 2y = 14

Therefore,

3x + 2y = 34

1 / 2x + 2y = 14

5 / 2 x = 20

5x = 40

x = 40 / 5

x = 8

3(8) + 2y = 34

2y = 34 - 24

2y = 10

y = 10 / 2

y = 5

Therefore, the two numbers are 8 and 5.

Explanation:

1)

1 kilometer is equal to 1000 meters:

1 km = 1000 m

So,

1m = 1/1,000 km

To complete the table, we can use the rule of three:

a) 1,000 m?

1m - 1/1,000 km

1,000m - x

x = 1/1000 * 1,000 = 1 km

As we can see, we only have to divide the measure in meters by 1000.

b) 3,500 m = 3,500/1,000 = 3.5 km

c) 500 m = 500/1,000 = 0.5 km

d) 75 m = 75/1,000 = 3/40 km = 0.075 km

e) 1 m = 1/1000 = 0.001 km

f) x = x/1,000 = 0.001x km

2)

The relation is:

Y = 0.001x

Where x is the measure in km and x in meter.

Explanation:

>> net income (total amount without the taxes etc...)

. biweekly = $575.50

. per month = $575.50 * 2 = $1,151 (~since it happens 2 times per month)

. per year = $1,151 * 12 = $13,812

>> gross income (total amount with the taxes etc...)

. per year = $17,500

>> amount deducted (~going to taxes etc...)

. per year = $17,500 - $13,812 = $3,688

. per month = $3,688 / 12 =~ $307.33

Mary has scored 78, 60, 82, 94, and 88 on her previous fice tests.

What score does she need on her next test so that her average (mean) is 80?

Let x be the next test score

Recall that the mean is given by

We have the following information,

mean = 80

sum of test scores = 78 + 60 + 82 + 94 + 88 + x = 402 + x

total number of tests = 6

So, let us substitute these values into the above formula

Therefore, Mary need to score 78 on her next test so that her mean is 80

The variables are

C: total cost ($)

S: amount of sugar (tons)

The equation that relates these two variables is;

C = 3250 + 125S

An equation is a mathematical expression that claims that two values are equivalent.

Equations use the equation symbol (=) to illustrate the equality of two or more expressions.

Algebraically, let Alyssa's algebra test score = x

Let Jennifer's test score = x + 8

The total of their two tests = 180

x + x + 8 = 180

2x + 8 = 180

2x = 180 - 8

2x = 172

x = 86 (172/2)

Alyssa's test score = 8 points lower

Shareable points = 172 (180 - 8)

Each received 86 points from the shareable points

Alyssa's test score = 86 points

Jennifer's test score = 94 points

Check:

86 + 94 = 180

94 = 8 points greater than 86

Step-by-step explanation

Point D in triangle DEF is the equivalent to point A in ABC. Similarly, E is the equivalent to B. In consequence, F is the equivalent to C.

We can obtain points D and E by translating points A and B 6 units to the right and 4 units up.

Translation 6 units to the right and 4 units up transforms the point (x, y) into (x+6, y+4). Applying this rule to point C:

C(-1, -2) → (-1+6, -2+4) → F(5, 2)
