Answer:
1/5
Step-by-step explanation:
20*5 = 100, so 20 is 1/5
Answer:
Quadratic functions are those where their rate of change changes at a constant rate. Exponential functions are those where their rate of change is proportional to itself.
An example of a quadratic function would be the shape that a ball makes when you throw it. Gravity causes a constant acceleration, the ball slows down as it is moving up, and then it speeds up as it comes down.
An example of an exponential function would be the population of a bacterium as long as there is enough space and nutrients or how your money grows with compound interest in a bank.
A quadratic function is one in the form
f(x)=ax2+bx+c
It’s rate of change (first derivative) is linear.
f′(x)=2ax+b
The rate of the rate of change (second derivative) is constant.
f′′(x)=2a
Quadratics are then the solutions to the differential equation
f′′=C
An exponential function is one in the following form.
g(x)=Aekx
It’s rate of change is another exponential function.
g′(x)=Akekx
So exponentials are the solutions to the differential equation
g′=kg

Answer:
4$
Step-by-step explanation:
Answer:
fourth option
Step-by-step explanation:
let t be tennis balls and g be golf balls, then
5t + 3g = 70 → (1)
2t + 5g = 85 → (2)
Multiplying (1) by 5 and (2) by - 3 will eliminate g
25t + 15g = 350 → (3)
- 6t - 15g = - 255 → (4)
Add (3) and (4) term by term to eliminate g
19t = 95 ( divide both sides by 19 )
t = 5
Substitute t = 5 into either of the 2 equations and solve for g
Substituting into (1)
5(5) + 3g = 70
25 + 3g = 70 ( subtract 25 from both sides )
3g = 45 ( divide both sides by 3 )
g = 15
Thus
$5 for tennis balls and $15 for golf balls
