2.5+105sin40 t -16 t^2 = 0
t = (-105sin(40) + sqrt(105^2sin^2(40)-4(-16)(2.5))) /2(2.5)
t = .235 seconds if i entered those right
Answer:280-10/5 (everything over/divided by 5)
Step-by-step explanation:
280 is all the students 10 go in car so subtract that and divide the answer by 5.
Formula for compound interest is stated as follows:
A = P(1+r)^n; where A = Amount in the bank after compounding, P = Principal amount deposited in the account, r = annual interest rate as a decimal, n = number of years to accumulate amount A in the account.
Using the values given;
9090 = P(1+0.058)^5
P = 9090/[(1+0.058)^5] = 9090/1.3256 = 6857.02
Therefore, the amount put in the account must be $6,857.02

X-5y=-21
x=-21+5y
-6(-21+5y)+4y=10
126+-30y+4y=10
126+-26y=10
