Answer:
Hence, the domain of the function is:
{4,7}
Step-by-step explanation:
We are given the range of the function:
as {25,16}
The function f(k) could also be written as:
The range is the value of the function at some k.
1)
if f(k)=25 then we have to find the value of k.
on taking square root on both side we have:
2)
if f(k)=64 then we have to find the value of k.
on taking square root on both side we have:
Hence, the domain of the function is:
{4,7}
The volume of a cone is

For the three basic trig identities (sin, cos, tan) there are three more which act as their reciprocals (csc, sec, and cot respectively)
A reciprocal of x can be represented as 1/x.
Therefore, cscӨ can also be represented as the reciprocal of sinӨ...1/sinӨ.
In that case, our answer should always be true so long as we put in a real number for theta, because that's the domain of sinӨ, right? However, we also have to satisfy the domain of cscӨ, and the limitations become extremely obvious when you look at this reciprocal identity equation...sinӨ cannot be zero because it is impposible to divide by zero! Looking at the unit circle, any multiple of π will make sin<span>Ө = 0, so there's your answer.

Answer:
First one: 37.5
Second one: 108
Step-by-step explanation:
For the first one:
the figure shown is a triangle
The area of a triangle can be calculated using this formula
where b = base length and h = height
The triangle shown has a height of 7.5 and a base length of 10
Using this information we plug in the values into the formula.
Hence the area of the figure is 37.5 square units
For the second one.
The figure shown is a parallelogram with a height of 9 and a base length of 12
The area of a parallelogram can simply be calculated by multiplying the base length by the height
So area = 9 * 12
9 * 12 = 108
Hence the area of the figure is 108 square units
