Answer:
Step-by-step explanation:
Total cost of the two T-shirts that you purchased is $25. The sales tax on the T-shirts is 8%. This means that the additional amount that you will pay on the T shirt is
25/100 × 25 = 0.25 × 25 = $6.25
The new cost of the T shirt would be the sum of the original cost and the value of the sales tax. Therefore,
New cost = 25 + 6.25 = $31.25
You have a $30 gift card from Amazon. The new cost of the shirts is higher than that value of the gift card. So the gift card will not cover the cost of the T shirts
I'll assume you're supposed to compute the line integral of over the given path . By the fundamental theorem of calculus,
so evaluating the integral is as simple as evaluting at the endpoints of . But first we need to determine given its gradient.
We have
Differentiating with respect to gives
and we end up with
for some constant . Then the value of the line integral is .
Answer: The length of radius of a circular pool is 7 meters
Step-by-step explanation:
Given that the circumference of a circular pool cover is about 88 meters
To find the length of radius
As we know circumference of a circle is given by
where C is circumference , and r is radius of the circle
Now as according to question we have
Hence,the length of radius of a circular pool is 7 meters
