The rule of the compounded interest is

A is the new value

P is the initial value

r is the rate in decimal

n is the period

t is the time

He invested $2000

P = 2000

The account earns an 8% annual interest

r = 8% = 8/100 = 0.08

The balance is for 4 years

t = 4

For no 1 it is annual, then

n = 1

Substitute these values in the rule above

Round it to the nearest cent means 2 d.p

The balance is $2720.98

2. Semi-annual means

n = 2

So we will substitute n by 2

Round it to the nearest cent

The balance is $2737.14 in semi-annual

3. Quarterly means

n = 4

So we will substitute n by 4

Round it to the nearest cents

The balance is $2745.57 quarterly

4. Monthly means

n = 12

Substitute n by 12

Round it to the nearest cent

The balance is $2751.33 monthly

2 - x = - 7

Adding x at both sides of the equal signe, we get:

2 - x + x = - 7 + x

2 = -7 + x

Adding 7 at both sides:

2 + 7 = -7 + x + 7

9 = x

1 tree requires 2/3 bags of mulch

Let the number of trees for 8 bags of mulch = y

1 tree = 2/3 bags

y = 8 bags

Cross multiply:

8(1) = y(2/3)

Hence, 8 bags of mulch require 12 trees (option C)

Answer:

first day=10 hours, second day=12 hours, third day=14 hours

Step-by-step explanation:

64+62+58=

126+58=184

o=day 1. t=day 2. th=day 3

o+t+th=36

o+4=th

64o+62t+58th=2196

(o+t+th=36)*58

58o+58t+58th=2088

64o+62t+58th=2196

-(58o+58t+58th)=2088

6o+4t=108

o+t+th=36

o+t+o+4=36 ==> th=o+4

2o+t+4=36

2o+t=32

(2o+t=32)*3

6o+4t=108

-(6o+3t=96)

t=108-96

t=12

2o+12=32 ==> 2o+t=32

2o=20

o=10

o+4=th

10+4=14

th=14

o=10, t=12, th=14

If Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, considering the rate of interest to be (R%) per annum, the domain and range for a function modeling the total amount of the investment, including interest are as follows:

Domain [X = {0 ≤ years ≤ 10}]

Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]

As per the question statement, Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, and since there is no information about the rate of interest of that investment, we are considering the rate of interest to be (R%) per annum.

We are required to determine the domain and range for a function modeling the total amount of the investment, including interest using the question statement mentioned data and our assumptions.

Since the starting principal amount, say P is $25,000, given,

Time of investment, say T is 10 years, also given,

And considering the interest rate per year to be R (%),

Then after 10 years, the total amount Vladimir has is [25000( 1 + xR)].

Where, the Domain (No. of years ) is [X = {0 ≤ years ≤ 10}]

And Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]

So first of all we have to solve this equation:

We can perform the operation 94+91=185 so we get:

And we can substract 185 from both sides of the equation:

Then the answer to part a is 215.

Now that we have the number of seats on the stage level we can find the max amount of money the theater can bring in. This will be given by the total number of seats in the stage level multiplied by the cost per ticket for these seats plus the total number of seats in balconies (185) multiplied by the cost per ticket for these seats. Then we get:

Then the max amount of money the theater can bring in for a show and answer to part b is $11075.

If we want to know how many times more robberies were in year 2 copare to year 4 we must take the number of robberies during year 2 and divide it by the number of robberies during year 4. If you take a look at graph A you'll notice that the bar above year 2 has its top at 285 and the bar corresponding to year 4 at 220. Then there were 285 robberies in year 2 and 220 in year 4 so we get the following:

If we round to two decimal places the answer is 1.30 times more robberies.

It's answer is option(C) i.e, 4/15

The average rate of function f  over the interval a≤x≤b is given by ,

(f(b) - f(a)) / (b - a)

It is the average amount by which the function changed per unit throughout that time period.

In this question the equation is given,

g(x) = log2 (x+6)-3

Solve this eq. by putting the values [-5, 10],

let, interval [-5, 10] = [a, b]

Then solve for g(a) and g(b), we know g(a) = g(-5),

g(-5) = log₂(-5+6) - 3

       = log₂1 - 3

       = 0 - 3

g(-5) = -3

Now, for g(b) = g(10)

g(10) = log₂(10+ 6) - 3

        = log₂16 - 3

        = 4 - 3

g(10) = 1

Now put these values in average rate formula,

Average rate = (g(b) - g(a)) / (b - a)

                      = (1 - (-3)) / (10 - (-5))

                      = (1 + 3) / (10 + 5)

                      = 4 / 15

Therefore, the average rate is 4/15 i.e, option(C)

Equation of the line

There are several forms to express the equation of a line.

The equation of the line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

The standard form of a line is:

Ax + By = C

We are given two points (1,2) and (3,10). The point-point equation is adequate according to the data we are provided.

Operating:

Subtracting 4x and adding 2:

y - 4x = -4 + 2 = -2

Rearranging:

-4x + y = -2

This is the required equation in standard form

The value of y in the expression [tex]2x^{2} - 23=y[/tex] is -21.

Given System of Equations are:

Now substituting x = 1 in in equation (1)

[tex]2x^{2} - 23 = y\\ y = 2x^{2} - 23\\ y = 2 x 1^{2} - 23\\ y = 2 x 1 - 23\\ y = 1 - 23\\ y = -21[/tex]

Answer:

hmmm, how about 242 divided by 11? the answer is 22 r0

Step-by-step explanation:

Non shadow part (white one) seems to be 1/4 of a circumference

So we need to find area of square minus area of 1/4 of the circumference

Square area = L^2 = 6^2 = 36

Circumference Area = (πr^2)/4 = (π*6^2)/4 = 28.27

Area of the shaded portion = 36 - 28.27 = 7.72

1) Note that this is a right triangle, and we can tell an isosceles one by the marks on the triangle.

2) So, we can use the Pythagorean Theorem, to find the side lengths since all we know for now is the hypotenuse:

We can discard the negative value for there is no negative length. So, the answer is 3

Answer:

Step-by-step explanation:

=====================================================

Explanation:

5624 is close to 5600

72 is close to 70

Therefore, 5624 ÷ 72 is close to 5600 ÷ 70 = 80

Think of it like saying 56 ÷ 7 = 8 but then we add the zeros onto each to get what is shown above.

--------

Use your calculator to find that

5624 ÷ 72 = 78.111 approximately

which isn't too far from the estimate value of 80. Our estimate is an over-estimate.

Answer: 80

Step-by-step explanation:

First change the equation to the nearest tenth,
5620 divided by 70

Now, break up the 70 into ( 10 * 7 )

So first do 5620 divided by 10

5620 divided by 10 = 562

Now if we round to the nearest tenth again we get 560

Now we can divide 560 by 7

Which comes out to 80

The cost of Brandon's taxi ride is $ 4.8.

A taxi ride in a large city costs $3.50 plus $6 for each mile traveled .The 3 mile cab ride includes a basic charge as well as the cost for the distance covered.If Brandon traveled 7.5 miles by taxi, how much was the cost, C, of his taxi.

For a 6 mile trip, the cost is $4.80 which means that :

The cost of 3 miles is $4.80−$3.00=$1.80

Therefore the cost for 1 mile is $1.80÷3=$0.60

The basic fee for hiring the cab is $3.00−$1.80=$1.20

So the total cost, c for a trip of d miles will be shown below:

c=0.6d+1.2

If d=3

c=0.6(3)+1.2=3

If d=6
