Step-by-step explanation:
Given

and 
So, 
Substitute the value of
in 


So it represent a parabola shown in the figure
Answer:
Step-by-step explanation:
Let the shorter side be x
Then the longer side is x + 1
<u>Perimeter is:</u>
- P = 2( x + x + 1) = 2(2x + 1) = 4x + 2
The value of perimeter is at most 60 meters. P ≤ 60.
<u>Solve the inequality:</u>
- 4x + 2 ≤ 60
- 4x ≤ 58
- x ≤ 58/4
- x ≤ 14.5
Since x is the integer, its greatest value is 14 m
Answer:
y = 3.5X - 6921.2
Step-by-step explanation:
Given the data :
X :
1990
1992
1994
1996
1996
Y :
45
51
57
61
75
Using an online regression calculator ; the regression model obtained is : y = 3.5X - 6921.2
Where ; slope = 3.5 ; intercept = - 6921.2
Answer:
The answer is $4.30
Step-by-step explanation:
Firstly, you will need to find how much tax is added to each price.
16(0.07)=1.12 (Note I changed the percent into decimal)
20(0.07)=1.4 (Note that I again changed the percent into a decimal)
16+1.12=17.12
20+21.4
To find the difference means to subtract.
21.4-17.12=4.28
Rounded to the nearest cent is $4.30
