A value raised by an exponent is the same as that value being multiplied by itself the number of times the exponent is.
(9m)^4 means 9m is multiplied by itself 4 times:
It can be written as: (9m)(9m)(9m)(9m)
The line rising to the right has equation y = x + 2
and the other one has equation y = -x + 4
the lines are solid so the inequalities will be <= or >=
in both case the shading is below so the sign is <=
also x and Y values are both positive
so the answer is choice C
Answer:
65
Step-by-step explanation:
You can use f(15) = 40 to solve for C, then find f(0), the initial temperature.
40 = f(15)
40 = Ce^(-0.045·15) +14 = .50916C +14
26 = .50916C
26/.50916 = C ≈ 51.065
Then f(0) is ...
f(0) = 51.065·e^0 +14 = 65.065 ≈ 65
The initial temperature of the water was 65 degrees Fahrenheit.
Answer:
StartFraction 1.55 over 1 EndFraction = StartFraction 3.5 over x EndFraction
Step-by-step explanation:
1 = 1.55
x = 3.5
1.55/1 =3.5/x
1.55/1 = 3.5/x correctly shows the equivalent ratios
