The graph shows how the distance an object traveled changed over time.
Pavlova-9 [17]
I believe the correct answer from the choices listed above is option D. The points where the object is traveling at the greatest speed would be <span>between points A and B because that slope is the steepest. The slope of this graph indicates speed since it will have the units of distance per time. The steeper the line is , the greater the value of the slope which would mean faster speed.</span>

You purchase a car worth $25077 and make a down payment of $3560. You intend to repay the balance of the car with month end car
zubka84 [21]

Answer:

value of buyout is $4185.74

Step-by-step explanation:

given data

car worth = $25077

down payment = $3560

monthly payment = $336 = 336 × 6 = $2016 per semi annually

time = 5 year  = 10 half yearly

rate = 4.04 %

to find out

value of final buyout

solution

we know here loan amount will be 25077 - 3560 = $21517

and we find present value first by formula that is

present value = \frac{amount(1+r)^t - 1}{r (1+r)^t}

put here t = 10 and r = \frac{4.04}{200}

so

present value = \frac{2016(1+\frac{4.04}{200})^10 - 1}{r (1+\frac{4.04}{200})^10}

present value = 18089.96

so

loan unpaid amount is here

loan unpaid amount = 21517 - 18089.96

loan unpaid amount = $3427.04

so

now we calculate value of buyout

that is express as

amount = principal × (1+r)^{t}

amount = 3427.04 × (1+\frac{4.04}{200})^{10}

amount = 4185.74

so value of buyout is $4185.74

0=-16t^2 +10 Solve for t
KengaRu [80]

Answer:

plus or minus √10 / 4

Step-by-step explanation:

0=-16t^2 +10 becomes easier to solve if we rewrite it as 16t^2 = 10.

Then t^2 = 10/16 = 5/8, and t = plus or minus √(5/8), or

                                             t = plus or minus (√5) / √8), or

                                             t = plus or minus (√5)√8         √5*2√2

                                                                         ------------- = -------------------

                                                                                 8                    8

or                                                                 plus or minus √10 / 4

The graph of a twice differential function is shown at right. Which of the following is true?
IRINA_888 [86]

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)
