Answer:
D
Step-by-step explanation:
Please refer to the attachment below.
We have a 30-60-90 triangle.
Hence, the ratios of the sides will be related as shown in the triangle below.
Let’s determine the value of x. In a 30-60-90 triangle, the hypotenuse is 2x.
Here, our hypotenuse is 10.
Then it follows that:
The side opposite to ∠A (60) is CB.
And it is x√3.
Hence, CB is 5√3.
The side opposite to ∠B (30) is AC.
And it is x.
Hence, AC is 5.
Therefore, AC is 5 while BC is 5√3.
Hence, our answer is D.
Answer:
B (second graph from left)
Step-by-step explanation:
The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.
Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.
