Answer:
28.26
Step-by-step explanation:
First find the radius by dividing the diameter by 2 (6/2 = 3) Now that we know that the radius is 3 you multiply it by 3 because you need the radius squared. (3*3 = 9) and then you multiply 9 by 3.14 and get your answer of 28.26.
The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120

Answer:
x = 9(sin 42)/(sin 29)
Step-by-step explanation:
We want to find an expression for x.
From the attached image, we can see a triangle with 2 angles given and 2 sides to be 9 and x respectively.
Now, the law of sines says that;
A/sin A = B/sinB = C/sin C
So applying it to this question, we have;
x/sin 42 = 9/sin 29
Thus,
x = 9(sin 42)/(sin 29)
