1 hour=60 minutes
1 day=24 hours=1440 minutes
1 week=7 days=10080 minutes
Answer
Step-By-Step Explanation
Given the function 
.
For each pair (t, f(t)) in the data points (0,5.5), (π/2,0.5), (π,−2.5), (3π/2,−7.5)
.
.
.
.
Expressing this as a system of linear equations in matrix form AX=B
Where
,
To determine the values of X, we use the expression
Therefore:
Therefore, the trigonometric function which fits to the given data is:
Coin: 50%; 1/2 chance to get heads
dice: 17%; 1/6 chance to get 2
<h3>
Answer: 4(x - 1)(x^2 + x + 1)</h3>
==================================================
Work Shown:
4x^3 - 4
4(x^3 - 1)
4(x - 1)(x^2 + x + 1)
In the last step, I used the difference of cubes factoring formula which is
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
Answer/Step-by-step explanation:
Earns per hour: $5.50
1 time fee : $2
Total = $35
( h - hours)
Equation :
5.50h + 2 = 35
First step is to suntract 2 from each side:
5.50h + 2 - 2 = 35 - 2
Simplify
5.50h = 33
Divide each side by 5.50 to seprate h from the numbers:
5.50h/5.50 = 33/ 5.50
H = 6
ANSWER: 6 hours
