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:
Volume=355 cm³
Step-by-step explanation:
I assume it should be 10 cm, not 10 m. If it is 10 m, everything will have to be adjusted.
Circumference = 2
r
10=2
r
10÷2
=r
1.59=r
V=
r²h
V=
(1.59)(71)
v=355
We need to find the quotient of the given division problem.

In order to find its quotient, we will use long division.
)
First of all, we put x in the quotient as
goes into
, x times.
So, we get:
)
(x

Upon subtracting, we get:

We can see that
goes into
, -2 times, therefore, the next term in the quotient will be -2. This makes our quotient as (x-2).
