Fatima opened a savings account with $7,500. She decided to deposit that same amount semiannually. This account earns 3.975% interest compounded semiannually. Exercises 5-7 are about Fatima's account. 5. What is the future value of the account after 10 years?​

Answers

Answer:

A = $11117.25

Step-by-step explanation:

Given the following data;

Principal = $7,500

Interest rate = 3.975% = 3.975/100 = 0.03975

Number of times, n = 2

Time, t = 10 years

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 7500(1 + \frac{0.03975}{2})^{2*10}[/tex]

[tex] A = 7500(1 + 0.019875)^{20}[/tex]

[tex] A = 7500(1.019875)^{20}[/tex]

[tex] A = 7500(1.4823)[/tex]

A = $11117.25

The number of portable widgets produced weekly by Widget, Inc., is related to the weekly profit in the way:
P(x) = -2x^2 + 88x - 384
where P(x) is the weekly profit in hundreds of dollars and x is the number of widgets must be produced weekly. How many widgets must be produced weekly for the maximum weekly profit? What is the maximum weekly profit? Find the analytically.

Answers

Answer:

22 widgets$58,400

Step-by-step explanation:

The turning point (maximum or minimum) of quadratic function ...

  f(x) = ax² +bx +c

is at x = -b/(2a).

Here, this means the maximum profit will be had when the number of widgets produced weekly is ...

  x = -88/(2(-2)) = 22

The profit at that level of production is ...

  P(22) = (-2·22 +88)(22) -384 = 44(22) -384 = 968 -384 = 584 . . . hundreds

22 widgets must be produced weekly for the maximum weekly profit of $58,400.

f(x)=18,000(.88)^x ; x represents the number of years since the car started to depreciate and 18,000 = the initial value of the car. What year will you recieve the car when the car value drops below $2,000? Please do a step by step

Answers

Answer:

After 17 years and 3 months

Step-by-step explanation:

Given function:

f(x)=18000(0.88)^x

We are looking for the value of x at f(x) < 2000

Solve the equation:

2000 = 18000(0.88)^x(0.88)^x = 2000/18000(0.88)^x = 0.1111log (0.88)^x = log 0.1111x = log 0.1111 / log 0.88x = 17.18

After 17 years and 3 months the car value drops below $2,000

Put f(x)=2000 and solve

2000=18000(0.88)^x2=18(0.88)^x1/9=(0.88)^xln(0.111)=xln0.88x=ln(0.111)/ln0.88x=17.18

Atleast 18 years

Six years ago a man's age was six times the age of his son. Four years hence, thrice his age will be equal to eight times his son's age. find their percent ages.​

Answers

Answer:

Present age =

fathers= 6x+6 = 36

sons = x+6 = 11

Step-by-step explanation:

-6:

father's age = 6x

sons age = x

Present age =

fathers= 6x+6

sons = x+6

+4 yrs:

father's age = 6x+6 +4 = 6x + 10

sons age = x+6 + 4 = x+ 10

3(6x +10) = 8( x + 10 )

18x+30 = 8x+80

18x-8x = 80-30

10x = 50

x= 50/10 = 5

~~~~~~~~~~

Present age =

fathers= 6x+6 = 36

sons = x+6 = 11

help pls all the questions i dont get it :(​

Answers

Answer:

A. The graph is not proportional, although it has a consistent slope, it does now go through the point of origin or (0,0). The equation of a proportional line is y=kx, so the y-intercept must be at (0,0).

B. Slope is found by  [tex]\frac{rise}{run}[/tex], from 1 point to the next, the y-value (rise) increases by 2 and the x-value (run) increases by 1, [tex]\frac{4}{1} = 4[/tex] giving us a slope of 4.

C. The y-intercept is the lines point of intersection with the y-axis. In the graph, this point is (0,10).

D. y = mx + b is the slope-intercept form where m is the slope and b is the y-intercept, the slope (m) is 4 and the y-intercept (b) is 10. y = 4x + 10

E. The equation is not proportional because the b value is 10 rather than 0.

Answer:

A. The graph is not proportional. I know this because the line doesn't go through the origin (0, 0). B. The slope (m) of the graph is 4. C. The y-intercept is 10. D. The equation in slope-intercept form is y=4x+10. E. The equation is not proportional. I know this because the line began from 10.

Step-by-step explanation:

The graph will be proportional when the line goes through the origin, (0, 0). The equation [tex]m=\frac{y2-x2}{y1-x1}[/tex] is used to solve for the slope (m). Pick any given points from the graph that's on the line to solve for slope (m). (0, 10) and (1, 14) makes it easier to solve for "m".

[tex]m=\frac{14-10}{1-0} =\frac{4}{1} =4[/tex] (4 is the slope)

Substitute x and y with any point given to find the y-intercept:

[tex]14=4(1)+b[/tex]

[tex]14=4+b[/tex]

[tex]-4[/tex]    [tex]-4[/tex]

----------------

[tex]10=b[/tex]

*Note that the y-intercept is always (0, any number)

Example: (0, -24)

Once you know what the slope and the y-intercept are, you'll have the equation set as y=4x+10.

In a study relating college grade point average to time spent in various activities, you distribute a survey to several students. The students are asked how many hours they spend each week in four activities: studying, sleeping, working, and leisure. Any activity is put into one of the four categories, so that for each student the sum of hours in the four activities must be 168. a) Consider the model GPA = β0 + β1study + β2work + β3leisure + β4sleep + u. Interpret the coefficient β1. Does it make sense to hold work, leisure, and sleep fixed, while changing study? b) Explain why this model violates Assumption MLR.3. c) How could you reformulate the model so that its parameters have a useful interpretation and it satisfies Assumption MLR.3?

Answers

Step-by-step explanation:

Given

GPA = NO + B1Study + B2work + B3leisure + B4sleep + u

1. No it makes no sense. There is an intercorellation between these explanatory variables. Changing study while holding the rest variables constant or fixed would not make sense. If study us changed then one or more of the other predictors should be changed so that they can still be equal to 168

2. Study is a perfect linear function of work, leisure and sleep. There is the problem of multicollinearity among these independent variables. One assumption of the MLR is no multicollinearity.

3. To reformulate model, you have to drop the variable that is having the issue. Let's say that leisure is dropped from the model. After this the assumption is satisfied.

GPA = b0 + B1Study + b2sleep + b3work + u

The table shows several points for function f(x).

A 2-column table with 8 rows. Column 1 is labeled x with entries negative 4, negative 2, 0, 2, 4, 6, 8, 10. Column 2 is labeled f (x) with entries 19, 15, 11, negative 6, negative 7, negative 8, negative 10, negative 14.

Which statement correctly identifies a point on the graph of f–1(x)?

A. The point (4, –7) is on the graph of f(x), so the point (7, –4) will be on the graph of f–1(x).
B. The point (–2, 15) is on the graph of f(x), so the point (2, –15) will be on the graph of f–1(x).
C. The point (–4, 19) is on the graph of f(x), so the point (–4, –19) will be on the graph of f–1(x).
D. The point (10, –14) is on the graph of f(x), so the point (–14, 10) will be on the graph of f–1(x).
