Answer:
sqrt(277) =x
x is approximately 16.64331698
Step-by-step explanation:
This is a right triangle since 14 is tangent to the circle and 9 is a radius
We can use the Pythagorean theorem to solve this problem
a^2 +b^2 =c^2
9^2+14^2 =x^2
81+196 = x^2
277 = x^2
Taking the square root of each side
sqrt(277) = sqrt(x^2)
sqrt(277) =x
Answer:
$10,000
Step-by-step explanation:
Cross multiply and divide by 55.
Hope this helps!
You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
Their frequency stays the same and their wavelength decreases
