X-doubling periods
Y-height of bamboo
Y=ab^x
1) make a table of values
X Y
1 5
2 10
3 20
2) write equations and substitute
5=ab^1 —> a=5/b^1 —> a=5/b
10=ab^2
Substitute into second equation
10=(5/b)*b^2
10=5b^2/b
10=5b
b=2
Substitute back in
b=2
10=a*2^2
10=4a
a=5/2
End equation:
Y=5/2*2^x
2km=2 kilometer
kilo=1000 so 2 km=2000m
25m
2500cm
cm=centimeter=1/100 of a meter
so
2500cm=25m
mm=milimeter=1/1000 meter
so
3000mm=3m
so the longets is obviously 2000m or 2km
If you times 39.99 by 0.20 (20%) then you get your answer of $7.99
｡ₓ ू ₒ ु ˚ Your answer would be 12.75! ˚ ू ₒ ु ₓ｡
⭒❃.✮:▹ Considering 15% of 14.99 is 2.24, we would need to subtract that amount from 14.99.
14.99 - 2.24 = 12.75. ◃:✮.❃⭒
Hope this helps! ♡
Answer:
See Explanation
Step-by-step explanation:
Given
(every hour)
Required
Explain why it is linear
First, we need to determine the equation that represents the scenario
Let x be the number of hours worked and y be the number of figurines at x hours.
The equation is determined as follows:
This gives:
Reorder
A linear equation is of the form
By comparison,
is equivalent to
<em>Hence, we can conclude that the situation is linear</em>
