It depends on the shape it may be rotation
Answer:
=3/4
Step-by-step explanation:
3 (c+d) 2c-2d
-------------- * -------------
(c-d) 8c+8d
Factor the right had term. The numerator can factor out a 2 and the denominator can factor out an 8.
3 (c+d) 2(c-d)
-------------- * -------------
(c-d) 8(c+d)
We can cancel the (c+d) in the numerator the left and the denominator on the right. We can cancel the (c-d) in the numerator on the right and the denominator on the left
3 2
-------------- * -------------
1 8
We can divide the fraction on the right by 2 on the top and bottom.
3 1
-------------- * -------------
1 4
=3/4
option 1 is not linear because it does not change by the same amount every year. It does not have a constant slope.
option 2 increases by 100 per year, constant slope, straight line, linear
-----------------------
a = A y^n
1100 =A y
1210 = Ay^2
1331 = A y^3
---------------
1210/1100 = y = 1.1
check 1331/1210 = y = 1.1 sure enough
1100 = A (1.1)
A = 1000
so
a = 1000 * 1.1^n
and the linear option 2
a = 1000+100n
You can put the numbers in for part C
10% compounded is better than 10% simple :)
Bill moves at 45 feet per minute and Greg 75 per minute and starts with a constant of 20 feet from them.
Let X be the number of minutes
Bill*Minutes +Greg*Minutes +20 = total distnce between
45x + 75x +20 = d
Plug in 2.5 for both values of x
45(2.5) + 75(2.5) + 20 =d
Multiply values by 2.5
112.5 + 165 + 20 = d
add together
Distance = 297.5 feet apart
