Answer:
3 1/4
Step-by-step explanation:
13/4
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is

By following the formula, cos=3/5 then:

Multiply everything (inside the square

root) by 5


Then just simplify

The answer is Square root of 20 over 5
circumference= 2(pi)r OR (pi)d
d is diameter and r is radius
if the circumference is given, then you would have to work backwards.
in this case, Circumference = 78.5 ft
the equal you would use for the radius would be 78.5 = 2 x 3.14(pi) x r
- multiply 2 x 3.14 and get 6.28
- divide 6.28 on both sides to get ‘r’ by itself
- 12.5 = r
next, for the diameter you can use C= (pi) x d
- 78.5 = 3.14 x D
- divide 3.14 on both sides to get ‘d’ by itself
- 25 = d

For letter b you do length times width times height
The revenue when the number of units is 18 is -135
<h3>How to determine the revenue?</h3>
The given parameters are:
Revenue function
R(x) = x *P(x)
Where
P(x) = 42/(4) − x
Substitute P(x) = 42/(4) − x in the equation R(x) = x *P(x)
R(x) = x * [42/(4) − x]
The number of units sold is 18.
So, we have:
R(18) = 18 * [42/(4) − 18]
Evaluate the expression
R(18) = -135
Hence, the revenue when the number of units is 18 is -135
