Answer:
At price 3 and 11, the profit will be $0
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>
A certain companies main source of income is a mobile app. The companies annual profit (in millions of dollars) as a function of the app’s price (in dollars) is modeled by P(x)=-2(x-3)(x-11) which app prices will result in $0 annual profit?</em>
My answer:
Given:
- x is the app price
- P(x) is the profit earned
If we want to find out the app price that will result in $0 annual profit? It means we need to set the function:
P(x)=-2(x-3)(x-11) = 0
<=> (x-3)(x-11)= 0
<=> x - 3 = 0 or x - 11=0
<=> x = 3 or x = 11
So at price 3 and 11, the profit will be $0
Hope it will find you well.
It's simple just equate the values one by one like when y is 5 put 5 in y's place and solve it like normal algebra and do the same with others
Answer:
b is y=2x+3, a is y=2x-2
Step-by-step explanation:
You just look at the y intercepts.
Since b intersects 3 in the y axis the y intercept is 3.
Since a intersects -2 in the y axis the y intercept is -2.
Answer:
Angle A = 100°
Angle B = 80°
Step-by-step explanation:
Supplementary angles means angles add up to 180°.
There are only two angles given here.
Angle A and Angle B add up to 180°.
A + B = 180°
4x + (2x + 30) = 180°
4x + 2x + 30 = 180°
6x + 30 = 180°
6x = 180 - 30
6x = 150°
x = 150 ÷ 6
x = 25°
Now substitute the x value to the angles.
Angle A:
4x
4(25) = 100°
Angle B:
2x + 30
2(25) + 30
50 + 30 = 80°
This is a compound figure
First, section off a triangle at bcd. The base is 8 units with a height of 2 units so the area is 8 square units.
Form a trapezoid between the areas where x is -3 to 1. Use the formula to find the area (28 square units).
There are two triangles left. Find the area of both of them (4 units and 2 units)
Add all of these values together to get a total of 42 square units
