Answer:
16
Step-by-step explanation:
Using the Remainder theorem
f(x) divided by (x + h) then the remainder is the value of f(- h)
here the divisor is (x + 3), thus remainder is f(- 3)
remainder = 5(- 3)² + 9(- 3) - 2 = 5(9) - 27 - 2 = 45 - 29 = 16
The practical dominion is from t = 0, when the ball starts motion until the time when the ball hits the ground.
To find the time when the ball hits the ground solve the equation:
h(t) = 0
=> -16t^2 + 68t = 0
Factor: t(-16t + 68) = 0 => t = 0 and -16t + 68 = 0
=> 16t = 68
=> t = 68/16
=> t = 4.25
So, the practical domain is 0 ≤ t ≤ 4.25 s.
Which also may be represented by t ∈ [0, 4.25s]
Answer:
A, B, C, D, F, G
Step-by-step explanation:
A. In order to stop overpayment when your account balance is low, some banks do require a low minimum balance so you don't use more money than you have
B. You can withdraw funds from a checking account easily by using an ATM or go into the bank.
C. There are many different kinds of checking accounts designed for specific activities.
D. One type of account is actually a Money Market account.
F. Some checking account can be joint so 2 or more people can access it (like wife and husband).
G. If you do overpay on your account, you will have to pay penalties for overspending.
E is incorrect because there are some few checking accounts that earn interest (very few).
H is incorrect because some banks require fees and restrictions.
Explanation:
4x+3y=37
y=x-4
4x+3(x-4)=37
4x+3x-12=37
add 12 to both sides
7x=49
x=7
Now you use plug in x
4(7)+3y=37
28+3y=37
subtract 28 to both sides
3y=9
y=3
answer: x=7 and y=3
