You can use the Cosine RUle to solve this
x^2 = 90^2 + 80^2 - 2*80*90 cos 120 = 21700
x = sqrt 21700 = 147.31 miles to nearest hundredth Answer
A solution of a quadratic equation (ax^2+bx+c) is the point at which the parabola crosses the x-axis. We can find this by using the Quadratic formula, which is
. We can solve the equation as follows:
Then we separate the negative from -28 to get:
Then we continue to solve by factoring common terms (-2 and 2). We get the solutions of
. Choice
B matches our first solution.

Answer:
A. h(x) = 111x + 44
Step-by-step explanation:
We have to add the two functions.
f(x) + g(x) = h(x)
= (58x + 21) + ( 53x + 23)
= 58x + 21 + 53x + 23
= (58x + 53x) + (21 + 23)
= 111x + 44
The function that represent the total employee is;
h(x) = 111x + 44
