Answer:
Step-by-step explanation:
Given that at time t, the position of a body moving along the s-axis is sequalsnegative t cubed plus 15 t squared minus 72 t m
i.e.
Velocity is nothing but s'(t) = derivative of s
and acceleration is s"(t) = derivative of v(t)
a) v(t) =0 when t = 4 or 6
b)
a(t) =0 when t =5
c) Distance travelled by the body from 0 to 5 would be
i.e. 110 miles (distance cannot be negative)
Answer:
No, he is wrong.
Step-by-step explanation:
Since, the total payment of a loan after t years,
Where,
P = present value of the loan,
r = rate per period ,
n = number of periods,
Given,
P = $165,000,
In loan 1 :
r = 3% = 0.03, t = 15 years,
So, the total payment of the loan is,
In loan 2 :
r = 4% = 0.04, t = 30 years,
So, the total payment of the loan is,
Since,
Hence, total amount repaid over the loan will be less for Loan 1.
That is, the friend is wrong.
Answer:
the number of possible selection is 12650
Option b) 12650 is the correct answer.
Step-by-step explanation:
Given the data in the question;
total number of students n = 25
number of student selected r = 4
= ²⁵C₄
= 25! / ( 4!( 25 - 4 )! )
= 25! / (4!(21)!)
= 12650
Therefore, the number of possible selection is 12650
Option b) 12650 is the correct answer.
