Answer:
The equation that can be used to determine the number of rounds that Emma golfs is:
x=(c-7.50)/6.25
Step-by-step explanation:
From the information given, the total amount Emma pays to go miniature golfing is equal to the price of the admission ticket plus the result of multiplying the price per round of golf for the number of rounds and according to this, the equation would be:
c=7.50+6.25x, where:
c is the total cost for Emma to go miniature golfing
x is the number of rounds
Now, you can solve for x to determine the equation that can be used to find the number of rounds that Emma golfs:
x=(c-7.50)/6.25
You can replace c with 26.25:
x=(26.25-7.50)/6.25
x=18.75/6.25
x=3
Answer:
-10
Step-by-step explanation:
(-4) + 4 + (-20) - (-10) = (-4) + 4 + (-20) + 10
= 0 + (-10)
= (-10)
(-4) + 4 = 0
-20 + 10 = -10. When two numbers have different sign, subtract and the result will have the sign of the bigger number. Here bigger number is 20 and So the result has a negative sign
Answer: 0.085
Step-by-step explanation:
Assuming you mean 10 to the power of -2, shift the decimal point two places to the left.
The given curve crosses the x-axis whenever x is a multiple of π, and it lies above the x-axis between consecutive even and odd multiples of π. So the regions with area S₀, S₁, S₂, ... are the sets
and so on, with
for natural number k.
The areas themselves are then given by the integral
Integrate by parts twice. Take
so that
then
so that
Overall, we find
or
Using the antiderivative and the fundamental theorem of calculus, we compute the k-th area to be
Since , the sum we want is a convergent geometric sum. As n goes to ∞, we have
