1 answer:
Answer: approximately 311 feet
I rounded to the nearest whole number since the other given values are whole numbers. The more accurate value is roughly 310.825323188148 feet.
=========================================================
Explanation:
Refer to the diagram below. When using the 47 degree as the reference angle, we know that,
- opposite side = x
- hypotenuse = 325
We can say:
sin(angle) = opposite/hypotenuse
sin(47) = x/425
425*sin(47) = x
x = 425*sin(47)
x = 310.825323188148
x = 311
The kite is approximately 311 feet off the ground.

Answer:
Answer B
Step-by-step explanation:
Notice that the quotient of f(x)/g(x) is:
therefore, this new function imposes conditions due to the fact that it has a square root in the numerator and a binomial in the denominator both with the variable x. Then, in order for the root in the numerator to be defined, the argument inside the root must be larger than or equal to zero. That is:
So, this condition must be satisfied by the x-values of the domain.
Then we have the binomial in the denominator, which in order to be defined needs to be different from zero. Notice that the only x-value that could cause problems (render zero) is:
Then,
So we have to eliminate the number 1 from the previous subset that required x smaller than or equal to 2.
The way to represent this Domain is then:
