For an object whose velocity in ft/sec is given by v(t) = −t2 + 2, what is its displacement, in feet, on the interval t = 0 to t = 2 secs?

1.333
2.438
2.667
−4

Answers

Answer 1

Answer:

1.333

Step-by-step explanation:

Distance travelled (or displacement) will be the antiderivative of Velocity.

Antiderivative of -t^2 + 2 =

d(t) = -t^3/3 +2t

Now plug in t=2 and t=0 and subtract them.

(-8/3+4)- (0/3 +0)= -8/3+4 = 1.333

Answer 2

Answer:

1.333

Step-by-step explanation:

We know that the displacement function is the integral of the velocity function. We are also given our bounds, 0 seconds to 2 seconds.

x(t) = [tex]\int\limits^2_0 {t^{2} +2} \, dt[/tex] = -t³/3 + 2t (evaluated from zero to two)

= [-2³/3 + 2(2)] - [-0³/3 + 2(0)] = 4/3 = 1.333...

Answers

How to find the percent:

32/368 = 0.0869
0.0869x100 = 8.69


8.869 is the percentage of the mocha cupcakes. To get the percentage of the chocolate ones, we subtract 8.69 from 100.

Answer:

a   [tex]P(X <  5) =  0.960[/tex]

b [tex]P(X >  8) = 0.016[/tex]

c   [tex]P(6 < x < 10) =  0.018 [/tex]

d  [tex] P(X < 6 or  X > 10 ) =  0.982 [/tex]

e  [tex]X =  2[/tex]

Step-by-step explanation:

From the question we are told that

   The probability density function is  [tex]f(x) =  \frac{2}{x^3}[/tex] for  x > 1

Considering question a

  [tex]P(x < 5) = \int\limits^5_1 {\frac{2}{x^3} } \, dx[/tex]

=> [tex]P(X <  5) =  [-\frac{1}{x^2} ]|  \left \ 5} \atop {1}} \right.[/tex]

=>[tex]P(X <  5) = - \frac{1}{25}  +   \frac{1}{1^2}[/tex]

=>  [tex]P(X <  5) =  0.960[/tex]

Considering question b

[tex]P(x > 8) =1  - \int\limits^6_1 {\frac{2}{x^3} } \, dx[/tex]

=> [tex]P(X > 8) =1-  [-\frac{1}{x^2} ]|  \left \ 8} \atop {1}} \right.[/tex]

=>[tex]P(X >  8) = 1 - [- \frac{1}{64}  +   \frac{1}{1^2}][/tex]

=>[tex]P(X >  8) = 0.016[/tex]

Considering question c

  [tex]P(6 < x < 10) = \int\limits^{10}_{6} {\frac{2}{x^3} } \, dx[/tex]

=> [tex]P(6 < x < 10) =  [-\frac{1}{x^2} ]|  \left \ 10} \atop {6}} \right.[/tex]  

=>[tex]P(6 < x < 10) =  [- \frac{1}{100}  +   \frac{1}{36}][/tex]

=>[tex]P(6 < x < 10) =  0.018 [/tex]

Considering question d

 [tex] P(X < 6 or  X > 10 ) = 1 - P(6 < x < 10) = 1 - \int\limits^{10}_{6} {\frac{2}{x^3} } \, dx[/tex]

=> [tex] P(X < 6 or  X > 10 ) =1-  [-\frac{1}{x^2} ]|  \left \ 10} \atop {6}} \right.[/tex]

=> [tex] P(X < 6 or  X > 10 ) =1- [- \frac{1}{100}  +   \frac{1}{36}][/tex] [/tex]

=> [tex] P(X < 6 or  X > 10 ) =  0.982 [/tex]

Considering question e

   [tex]P(X  <  x ) =  \int\limits^x_1 {\frac{2}{x^3} } \, dx  =  0.75[/tex]

   [tex]P(X  <  x ) =  [- \frac{1}{x^2} ]| \left \ x } \atop {1}} \right.  =  0.75[/tex]

   [tex]P(X  <  x ) =  - \frac{1}{x^2} - [- \frac{1}{1^2} ]= 0.75[/tex]

   [tex]P(X  <  x ) =  - \frac{1}{x^2} + 1 = 0.75[/tex]

     [tex]  - \frac{1}{x^2}  = -0.25[/tex]

     [tex]X =  2[/tex]

Write the slope-intercept for of the equation of the line with that passes through the point (2,-8) and is perpendicular to 2x+3y=15

Answers

Answer:

y = 3/2 x - 11

Step-by-step explanation:

Recall that a perpendicular line to the expression:

2 x + 3 y = 15

3 y = - 2 x + 15

y = - 2/3 x + 15/3

is going to have a slope equal to the opposite of the reciprocal of the original (-2/3) slope. So, the slope of the perpendicular line must be: 3/2.

We use this value in a general point-slope form of a line, where we use the point (2, -8) :

y - (-8) = 3/2 (x - 2)

y + 8 = 3/2 x - 3*2/2

y + 8 = 3/2 x - 3

y = 3/2 x - 3 - 8

y = 3/2 x - 11

Bongeka purchased a new refrigerator and were expected to pay R1 684,00 five months ago and another R1 323,00 in eight months’ time. She could not make the payment five months ago, but after receiving a bonus at work, she rescheduled to repay the loan in two equal payments, the first due in two months and the second due in five months’ time. The payment at month five will settle the debt, therefore, the settlement date is month five. The debts and payments are subject to the same interest rate of 11,4% per annum, compounded monthly.

Answers

The discount factor computed shows that the value of each payment will be $1546.

How to calculate the payment?

The following can be deduced from the information:

Payment due in 5 months = $1684

Payment due in 8 months = $1323

Annual interest  = 11.40%

Monthly interest rate = 11.40%/12 = 0.95%

Present value of payment due 5 months ago = $1684 + (1 + 0.95%)⁵ = $1765.52

Present value of payment due 8 months ago = $1226.62

Total present value = $1765.52 + $1226.62 = $2992.14

After rescheduling, the payments will be in 2 months and 5 months.

Discount factor for payment due in 2 months = 0.9813

Discount factor for payment due in 5 months = 0.9538

Combined discount factors= 0.9360

Therefore, the value of each payment will be:

= $2992.14/(1 + 0.9360)

= $1546
