The graph in the problem is interpreted as follows

What interpretation can be made from the y-intercept?

the y-intercept shows start the timing started when the cheetah is not running

How can the point (3.0, 12) on the graph above be interpreted? At 3.0 s the cheetah was running at 12 m/s

What is the output value of this graph when the input value is 5.0?

the output is 30

Does the graph above have a constant rate of change?

No, the rate of change varies

The term "rate of change" describes the rate at which something changes over time.

Thus, it is not the amount of individual changes themselves but rather the acceleration or deceleration of changes (i.e., the rate).

When the ratio of the output to the input remains constant at every given point along the function, the rate of change is said to be constant.

The slope is another name for the constant rate of change. The rate of change for linear functions will be constant.

Using a system of equations, Mike should invest $66,000 in investment A and $24,000 in investment B to earn $5,220 from both funds per year.

We can solve a system of equations to determine the amounts that should be invested in each fund to earn the stated amount yearly.

A system of equations is also called simultaneous equations because they can be solved together.

The total investible funds = $90,000

The expected annual earnings = $5,220

The earnings from investment A = 5% or 0.05

The earnings from investment B = 8% or 0.08

A + B = 90,000  ... Equation 1

0.05A + 0.08B = 5,220 ... Equation 2

Multiply equation 1 by 0.05:

0.05A + 0.05B = 4,500 ... Equation 3

Subtract Equation 3 from Equation 2:

0.05A + 0.08B = 5,220

-0.05A + 0.05B = 4,500

=0.03B = 720

= 24,000 (720/0.03)

B = $24,000

From Equation 1, substitute B = 24,000 to get A:

A + B = 90,000

A + 24,000 = 90,000

= 66,000

A = $66,000

Thus, we can conclude that Mike with $90,000 should invest $66,000 in Investment A earning 5% per year, and $24,000 in Investment B earning 8% annually to earn a total of $5,220 from both funds.

Interest in $2800 when deposited $7,000 in an account earning 10% interest compounded annually.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest. Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows $5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.

Answer: 3,248.70

Step-by-step explanation: You can use this formula when working with compound interest:

B=p(1+r)t

In this formula, B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

The interest is the balance minus the principal.

solve

Write the rate as a decimal.

10%=0.10

Calculate the balance.

B

= p(1+r)t

= $7,000(1+0.10)4

= $7,000(1.10)4

= $7,000(1.4641)

= $10,248.70

Now use this to find the interest, which is the balance minus the principal.

$10,248.70–$7,000=$3,248.70

The interest will be $3,248.70.

Answer:

the equation 10 = x - y

Step-by-step explanation:

Let x represent the initial value of the investment, and let y represent the amount of money that each person receives after the investment is withdrawn.

We know that the cost of withdrawing the investment is $10, so we can write the equation 10 = x - y. We also know that each person receives $40, so we can write the equation y = 40.

We can now solve for x by substituting the value of y into the first equation. Since y = 40, we can substitute 40 for y in the equation 10 = x - y to get 10 = x - 40. Solving this equation for x, we find that x = 50.

Therefore, the initial value of the investment was $50.

Answer:

  A.  $510.75

  B.  $6,129.00

  C.  8.63%

Step-by-step explanation:

You want the monthly payments, total amount paid, and fraction going to interest for the payoff of a $5600 credit card balance at an annual rate of 17% interest.

The monthly payments can be found using the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12)) . . . . . P is the principal amount, r is the rate

This formula gives the monthly payment for payoff in 1 year.

  A = 5600(0.17/12)/(1 -(1 +0.17/12)^-12) ≈ 510.75

The monthly payment is $510.75.

You will have made 12 monthly payments of $510.75, for a total of ...

  12 ×  $510.75 = $6,129.00

You will have paid $6,129.00.

The fraction of your total payoff that goes to interest is ...

  (6129 -5600)/6129 = 1 -(5600/6129) ≈ 0.0863 = 8.63%

About 8.63% of your total payment is interest.

__

Additional comment

Spreadsheets and calculator apps can be used to find these values. You need to be careful to specify that payments are made at the end of the month.

The amount to interest is slightly more than half the interest that would be due if the interest rate were used to calculate simple interest. Our answer of 8.63% is slightly higher than 17%/2 = 8.5%, so passes the reasonableness check.

What is an equation?

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. Since we can balance this by deducting the right-side expression from both sides' expressions, this won't limit the generality.

A condition on a variable is what an equation in algebra is. It can only be satisfied if the variable has a specific value. That indicates that only the value of x = 9 may satisfy the equation 2x - 5 = 13.

(a) The probability that more than three aircraft arrive within an hour is 0.2970.

(b) The probability that no interval contains more than three arrivals is 2.56.

(c) The length of an interval of time is 0.891 hours.

The time between arrivals of small aircraft at a country airport is exponentially distributed with a mean of one hour.

(a) We will find the probability that more than three aircraft arrive within an hour,

P(X > 3) = 1 - P(X ≤ 3)

             = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3))

             = 1 - [ ( [tex]e^{-4/3}[/tex] 1° / 0!) + ( [tex]e^{-4/3}[/tex] 1¹ / 1!) + ( [tex]e^{-4/3}[/tex] 1² / 2!) + [tex]e^{-4/3}[/tex] 1³/ 3!]

             = 1 - (0.7029)

P(X > 3) = 0.2970

(b) Now we calculate probability that no interval contains more than three arrivals if 30 separate one-hour intervals are chosen,

(1 - P(X > 3)³°) = (1 - 0.2970)³°

                      = 2.56

(c) Let the length of an interval of time is t, the calculation for t is given as;

P(X = 0) = 0.41

[tex]e^{-t}[/tex](t)° / 0! = 0.41

          [tex]e^{-t}[/tex] = 0.41

          - t = ln(0.41)

          - t = -0.891

            t = 0.891 hours

Therefore the length of an interval of time such that the probability that no arrivals occur during the interval is 0.41 is 0.891 hours.

Part A:

This data appears to be modeling a geometric sequence because the time to complete each station is increasing by a constant factor. For example, the time to complete station 2 is 4 minutes, which is double the time it took to complete station 1. Similarly, the time to complete station 3 is 8 minutes, which is double the time it took to complete station 2, and so on.

Part B:

To find the time Aurora will take to complete station 5 using a recursive formula, we can use the formula:

a_n = a_1 * r^(n-1)

where a_n is the time it takes to complete station n, a_1 is the time it takes to complete station 1, and r is the common ratio (the factor by which the time increases from one station to the next).

We are given that a_1 = 2 and a_2 = 4, so we can solve for r:

r = a_2 / a_1

= 4 / 2

= 2

Then we can use this value of r to find the time it takes to complete station 5:

a_5 = a_1 * r^(5-1)

= 2 * 2^4

= 2 * 16

= 32

Therefore, Aurora will take 32 minutes to complete station 5.

Part C:

To find the time Aurora will take to complete station 9 using an explicit formula, we can use the formula:

a_n = a_1 * r^(n-1)

where a_n is the time it takes to complete station n, a_1 is the time it takes to complete station 1, and r is the common ratio (the factor by which the time increases from one station to the next).

We are given that a_1 = 2 and a_2 = 4, so we can solve for r:

r = a_2 / a_1

= 4 / 2

= 2

Then we can use this value of r to find the time it takes to complete station 9:

a_9 = a_1 * r^(9-1)

= 2 * 2^8

= 2 * 256

= 512

Therefore, Aurora will take 512 minutes to complete station 9.
