The given function is
f(x) = 4x - 3/2
where
f(x) = number of assignments completed
x = number of weeks required to complete the assignments
We want to find f⁻¹ (30) as an estimate of the number of weeks required to complete 30 assignments.
The procedure is as follows:
1. Set y = f(x)
y = 4x - 3/2
2. Exchange x and y
x = 4y - 3/2
3. Solve for y
4y = x + 3/2
y = (x +3/2)/4
4. Set y equal to f⁻¹ (x)
f⁻¹ (x) = (x + 3/2)/4
5. Find f⁻¹ (30)
f⁻¹ (30) = (30 + 3/2)/4 = 63/8 = 8 (approxmately)
Answer:
Pedro needs about 8 weeks to complete 30 assignments.
This would be an exponential graph and non of the answers are exponential. but the graph would be f(x)=3^x
Answer:
I'll give you the answers for 1 - 5: 1). 24, 2).19, 3)10, 4)13, 5)-17
Step-by-step explanation:
You simply substitute the corresponding values for the corresponding function:
f(6) if f(x) = 4x so, f(6) = 4(6) = 24
Another example:
f(5) if f(x) = 3x - 2 so, f(5) = 3(5) - 2 = 15 - 2 = 13
The correct answer is 3.
The formula for the law of sines is the following:
P/sin P = Q/sin Q = R/sin R
So, if you break these up into two different equations, you will have:
P/sin P = Q/sin Q and P/sin P = R/sin R
To solve, get P alone on one side of the equation by multiplying the other side by sin P:
P = Q sin P/sin Q and P = R sin P/sin R
When you look at the answers, you'll see that the second equation is an option.
