Is the distance between them 
Given that there are two points, the distance between them is calculated using
Distance = 
In this case;
Substitute these in the given formula
Distance = 
Comparing this with the given formula, both are not the same;
Hence, the formula is false and the correct formula is of the form
Let x be the number of pens in a box.
Jill : three full boxes of pen and 2 loose pens. 3x + 2
Ben: two full boxes of pen and 14 loose pens. 2x + 14
Jill and Ben have the same pens.
Jill = Ben
3x+2 = 2x + 14
3x - 2x = 14 - 2
1x = 12
x = 12
To check:
Jill = Ben
3x + 2 = 2(x) + 14
3(12) + 2 = 2(12) + 14
36 + 2 = 24 + 14
38 = 38
There are 12 pens or a dozen of pens in a full box.
The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx
Answer:
19/4 or 4.75
Step-by-step explanation:
Week 1: 1 1/8 = 1.125
Week 2: -2 5/8 = -2.625*
Week 3: 1 3/4 = 1.75
Week 4: -1 1/2 = -1.5
Week 5: 2 1/8 = 2.125*
2 1/8 - (-2 5/8) = 2.125 - (-2.625)
19/4 or 4.75
