Answer:
$91.75
Step-by-step explanation:
babysitting = B
Farmers Market = F
9.5B + 12.25F = Total money earned
9.5 (4.5) + 12.25 (4) = $91.75
Answer:
-1
Step-by-step explanation:
We can find the tangents to the curve at x = 0, where the roots of the function occur (function crosses the x-axis). We can differentiate the function with respect to x by using implicit differentiation.
We will need to use the Power Rule and Product Rule to differentiate this function.
Distribute 2 inside the parentheses.
Move all terms containing dy/dx to the left side of the equation, and all other terms to the right side of the equation.
Factor dy/dx from the left side of the equation.
Divide both sides of the equation by 2x + 2y.
Factor the negative sign out of the numerator.
Cancel out the numerator and the denominator.
The derivative of the function is -1 at all points, meaning that everywhere the function has a slope, or tangent, of -1.
The common slope of the tangents as the curve x² + 2xy + y² = 9 crosses the x-axis is -1.
1. C (x+8)^2
2. D y=6^x
3. D t/2.35 ; 2.13 ft.
4. A (7h^2-2h)/2; 672 cm^2
5. A 4.50 h ; $7.88
For one and two you just have to plug in the numbers into the equation to see what works.
Three four and five you have to read the problems and come up with an equation to get your answer. Please comment if you need to see the work!
Answer:
0
Step-by-step explanation:
12 + 8 = 20
If we then take 20 from 20, you get 0.
