Answer:
k = -3
Step-by-step explanation:
F(x) has a positive slope
g(x) has a negative slope
Let x = -3
The y value goes from 1 to -3
g(x) = k⋅f(x)
-3 = k(1)
-3 = k
Answer should be 36.95 if 1.4 is the radius
The third option is quadratic
If 40% are boys, 60% are grills.
As fractions:
4/10 = 2/5 are boys
6/10 = 3/5 are grills
70% or 7/10 of the boys arrive by car:
(2/5)(7/10) = 14/50 = 7/25
And 60% or 3/5 of the grills arrive by car:
(3/5)(3/5) = 9/25
So in total we have 7/25 + 9/25 = 16/25 = 64/100 = 64%
64% chance that a child arrives by car.
2.85 + 3.15 = 6 (total kilograms)
2.85/6 = 0.475...multiply by 100 t get the percent = 47.5% (sugar)
