Answer:
f(-4) = 56
Step-by-step explanation:
f(x) = 3x² - 2x
To find f(-4), substitute -4 for all the values of x in f(x).
f(-4) = 3(-4)² - 2(-4)
Square -4.
f(-4) = 3(16) - 2(-4)
Multiply 3 and 16.
f(-4) = 48 - 2(-4)
Multiply -2 and -4.
48 + 8
Add.
56

Step-by-step explanation:

Answer:
R, in beats per minute, can be approximated by the formulas, where a represents the person's age.
where R= 143 - 0.65a for women.... (1)
and R= 165 - 0.75a for men,..... (2)
So by implementing these two equation we get a = 40
So the age will be 40 years old

Answer:
the present value of the lease obligation for lease A will be $1,702,712.74 while the present value of lease B will be $1,764,741.73
Step-by-step explanation:
the present value of annual lease payment will be determined by discounting the total amount to be received from lease payment over years.
for lease A , Pv = A 
= $200,000( 1 - (1+0.1)
) / 0.1 = $1,702,712.74
for lease B , Pv = $220,000( 1 - (1+0.1)
) / 0.1 = $1,764,741.73
