If you want the answer youse a calculator or do 21 divided by 38
Answer:
The first deal is better because it has more balloons for not too much of a price (individually)
Step-by-step explanation:
15*4= 60
60/18= 3.33
Deal 1= 3.33 for each balloon
10*5= 50
50/16=3.125
The functions supplied appear to be the same? Regardless:
We have the equation y = 5x.
Therefore the gradient of this graph will be 5, so for every 1 increase in the y axis, there will be 5 in the x.
It will appear as a straight line passing through the origin and the point (1, 5).
A.
h(x)=3*5ˣ; h(0)=3, h(1)=15: rate of change is (15-3)/1=12 (1st section)
h(2)=3*25=75, h(3)=3*125=375: rate of change (375-75)/1=300 (2nd section)
b.
So the second section is 300/12=25 times greater than the first section.
The function is exponential and as x gets larger the difference between consecutive values of h(x) increases dramatically so the rate of change increases.
