Answer:
The initial temperature of the coffee was 90°C.
Step-by-step explanation:
The function representing the temperature of the coffee after <em>x</em> minutes is:
T is the temperature in degree Celsius.
The initial temperature of the coffee will be at <em>x</em> = 0.
Compute the value of T (x) at x = 0 as follows:
Thus, the initial temperature of the coffee was 90°C.
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64
Therefore, a = 16.
Answer:
Solve for x = all values of x are solutions
or
0
Step-by-step explanation:
Simplify the following:
(-2 (x + 5))/3 + 4 (x + 5) - (10 (x + 5))/3
Put each term in (-2 (x + 5))/3 + 4 (x + 5) - (10 (x + 5))/3 over the common denominator 3: (-2 (x + 5))/3 + 4 (x + 5) - (10 (x + 5))/3 = (-2 (x + 5))/3 + (12 (x + 5))/3 - (10 (x + 5))/3:
(-2 (x + 5))/3 + (12 (x + 5))/3 - (10 (x + 5))/3
(-2 (x + 5))/3 + (12 (x + 5))/3 - (10 (x + 5))/3 = (-2 (x + 5) + 12 (x + 5) - 10 (x + 5))/3:
(-2 (x + 5) + 12 (x + 5) - 10 (x + 5))/3
(12 (x + 5) - 10 (x + 5)) - 2 (x + 5) = 0:
0/3
0/3 = 0:
Answer: 0
Decimal i know this because of the dot also known as a decimal
Answer:
f(n) = 6* (3)^(n-1)
Step-by-step explanation:
We are multiplying by 3 each time
6*3 =18
18*3 = 54
So the common ratio is 3
The first term is 6
The formula for the geometric sequence is
an = a1 r^(n-1)
an = 6* (3)^(n-1)
f(n) = 6* (3)^(n-1)
