.50 + .40m = .48m where m is the number of minutes that equalize the cost......subtract .40m from each side
.50 = .08m divide both sides by .08
.50 /.08 = m = 6.25 minutes
It is rather obvious that we will have to deal with a trigonometric function. Let us see... the first hint is that a function is not defined somewhere. cos and sin are defined for all real numbers... what about tan though? Well, as we approach pi/2, tan becomes larger and larger and it is not defined at pi/2. Given that the tan function has a period of pi (cos and sin have a period of 2pi), this function is the right candidate. Since it is periodic and it is not defined at pi/2, it cannot be defined at any x=pi/2+-npi (if it was defined for some n, then it would have the same value at pi/2 due to periodicity). Hence, a function that works is tanx, or 2*tanx or tanx+6.
Answer:
128 servings
Step-by-step explanation:
5/4 cups of milk for 10 servings is equal to 1/8 cup per 1 serving
there are 16 cups in a gallon
let 'n' = # servings in a gallon
so 1/8 : 1 is 16 : n
1/8n = 16
n = 16(8)
n = 128
Answer:
<u>Two</u>
============================
Step-by-step explanation:
The solution for any system of equations is the intersection points between the graph that representing the system of equation.
So, for the given system of equation, we have a circle and a parabola.
As shown in the figure, The circle and parabola are intersects at two points
So, there are two solutions for the system of equations on the graph.
So, The answer is option two.
