If you contribute $8,000 every year for 5 years, the interest would you would earn during the 5 years is:6005.91

What is future value of annuity?

The future value of the annuity means the future worth of 5 annual contributions  of $8000 every year, based on the fact that the deposits would earn 7.0% interest rate every year, in short, the worth of the savings in 5 years can be determined using the future value of an ordinary annuity as shown below:

FV=PMT*(1+r)^N-1/r

FV=accumulate balance after 5 years=unknown

PMT=annual savings=$8,000

r=interest rate per year=7.0%

N=number of annual payments over 5 years=5

FV=$8000*(1+7.0%)^5-1/7.0%

FV=$46,005.91

Total deposits in 5 years=$8000*5=$40,000

Interest =FV-total deposits

interest=$46,005.91-$40,000

interest=$6,005.91

Answer:First, determine the total number of hours worked by multiplying the hours per week by the number of weeks in a year (52). Next, divide this number from the annual salary.if an employee has a salary of $50,000 and works 40 hours per week, the hourly rate is $50,000/2,080 (40 x 52) = $24.04.

Step-by-step explanation:

Divide the gross pay by the wage hours worked. For example, if your records show that the employee was paid $4,000 for the total month, divide 4,000 by 172 to reach $23.26. This is an accurate representation of an hourly rate for that employee's monthly work.

On a long hike Lucy drank 6 pints of water, which is equal to 3 quarts.

An English measurement of volume equal to one-quarter gallon is the quart. There are now three different types of quarts in use: the liquid quart, dry quart, and imperial quart of the British imperial system. One liter is roughly equivalent to each. It is divided into four cups or two pints (in the US). The precise dimensions of the quart have historically changed in line with shifting values of gallons over time and in relation to various commodities.

A measure of liquid capacity that is equal to two pints or a quarter of a gallon, or roughly 0.94 liter in the US and 1.13 liter in the UK.

Since, 1 quart = 2 pints

Therefore by unitary method we can say,

2pint= 1 quart

The coordinates of G after it is rotated by 90 degrees will be ( 3, 4 ).

The process of changing the location of the image on the coordinate system will be known as the translation.

Our point A(x,y) becomes A' when a point is rotated 90 degrees counterclockwise about the origin (-y,x). To put it another way, flip x and y, and make y-negative.

Given that point, G is translated to 90 degrees. The translated coordinates of point G will be calculated as:-

( -x, y ) = ( y, x )

( -4 , 3 ) = ( 3 , 4)

Therefore, the coordinates of G after it is rotated by 90 degrees will be ( 3, 4 ).

f(x) = x² - 3x + 5

f(-2) = (-2)² - 3.(-2) + 5

f(-2) = 4 + 6 + 5

f(-2) = 15

Answer:

Step-by-step explanation:

Comment

In general, f(x) can be thought of as being y. So the equation could read as "Let x = - 2" when y = x^2 - 3x + 5.

Another way of thinking of it is by saying f(-2), wherever you see an x on the right hand side, substitute the value given on the left side (in this case x = - 2

Solution

f(-2) = (-2)^2 - 3x + 5

f(-2) = 4 - 3(-2) + 5                   Combine

f(-2) = 4 + 6 + 5                        Add

Answer:

Step-by-step explanation:

The difference quotient of the function f(x) = 4x + 2 is 4.

Functions were originally the idealization of how a varying quantity depends on another quantity.

The given function is,

f(x) = 4x + 2

For a given function f(x), we define the difference quotient as:

[tex]\frac{f(x+ h)-f(x)}{h}[/tex]

Thus, for the given function, difference quotient is given as,

[tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4(x+h)+2-(4x+2)}{h}[/tex]

expanding the brackets we get,

[tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4x+4h+2-4x-2}{h}[/tex]

Solving we get,

⇒ [tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4h}{h}[/tex]

Thus,we get

⇒ [tex]\frac{f(x+ h)-f(x)}{h}[/tex] = 4

Thus, the difference quotient of the function f(x) = 4x + 2 is 4.

M lies on both graphs

Then

the coordinates of M verify both equations (equation of graph1 and equation of graph 2)

Then

[tex]b=8^{a}\ \text{on the other hand} \ b=2^{a+2}[/tex]

Then

[tex]8^{a}=2^{a+2}[/tex]

Therefore ‘a’ (the x-coordinates of the points M where the two graphs intersect) is a solution to the equation :

[tex]8^{x}=2^{x+2}[/tex]

Part B : check the attached table.

Part C :

Graphically, we try to spot the points of intersection of the two graphs ,the x-coordinates of those points are the solution to our equation.

A linear equation in two variables is one that is written in the form ax + by + c = 0, where a, b, and c are real numbers and also the coefficients of x and y, i.e. a and b, are not equal to zero.

For the given question.

Let 'x' be the number of matinee showings.

Let 'y' be the number of prime-time showings.

Then. the total ticket sold are 1,411.

Thus, x + y = 1,411.

or, x = 1,411 - y

The cost of one matinee showings is $9.

The cost of one prime-time showings is $13.50.

Now, the total cost earned is $17,149.50.

So,

9x + 13.5y = 17,149.50

Put the value of the 'x' in the above equation.

9(1,411 - y) + 13.5y = 17,149.50

Simplifying;

12699 - 9y + 13.5y = 17,149.50

4.5y = 4450.5

y = 989.

Calculate x;

x = 1,411 - 989

x = 422

Therefore, the number of matinee and prime-time movie tickets were sold that day are 422 and 989.
