Answer:
$125 per week
Step-by-step explanation:
Andrew earns $6.25 per hour. If he works for 4 hours, solution will be:
$6.25 × 4 = $25 per day.
If Andrew works 5 days per week, then he earns
$25 × 5 = $125 per week.
Therefore by estimate, Andrew earns $125 per week.
Answer:
<h3>π/2</h3>
Step-by-step explanation:
Given the expression;
secθ − tan θ = cosθ
We are to find the solution in the interval [0, 2π).This is as shown;
From trigonometry identity;
secθ = 1/cosθ
tanθ = sinθ/cosθ
Substitute into the formula;
secθ − tan θ = cosθ
1/cosθ-sinθ/cosθ = cosθ
Multiply through by cosθ
1 - sinθ = cos²θ
1-sinθ = (1-sin²θ)
1-sin²θ-1+sinθ =0
-sin²θ+sinθ = 0
sin²θ = sinθ
sinθ = 1
θ = arcsin 1
θ = 90
θ = π/2
Hence the solution is π/2
#1) Arrange the numbers from least to greatest.
#2) If there is a odd amount of numbers the middle number is your answer.
but if there is a even amount of numbers, take those two middle numbers, add them, then divide them by two. Then you got your answer.
Inverse functions are always the opposite of course therefore, f^-1(x)=x+12
