Find the greatest common factor of 18 and 35
Flura [38]

Hi,

Let's look at the factor list:

The factors of 18 are 1, 2, 3, 6, 9, and 18.

The factors of 35 are 1, 5, 7, and 35.

The only common factor is 1, so the greatest common factor is 1.

Have a great day!

If f(x) varies directly with x2, and f(x) = 40 when x = 2, find the value of f(6). 36 60 120 360
pav-90 [236]
<span>The answer is 360.
f(x) varies directly with x^2 and f(2) = 40. What does that mean?</span>
<span>It means this f(x) = k* x^2. We need to find k.
For x=2, f(x) = 40, this means k* x^2 = 40. BUT, x=2.
This means p* 2^2 = 40. => k = 40 / 4 = 10.
We just found what f(x) is: f(x) = 10x^2.
Now, what is the value of f(6)?
Just replace the value of k by 10. => f(6) = 10* 6^2 = 10*36 = 360</span>

If $3000 is deposited in an account that pays 5% interest, what is the difference in the amount after 4 years between the amount
monitta
If the interest is compounded annually, then
A = P*(1+r/n)^(n*t)
A = 3000*(1+0.05/1)^(1*4)
A = 3646.51875
which rounds to 3646.52
Call this value x, so x = 3646.52
-----------------------------------
If the interest is compounded using simple interest, then
A = P*(1+r*t)
A = 3000*(1+0.05*4)
A = 3600
Call this value y, so y = 3600
-----------------------------------
Now subtract x and y
x-y = 3646.52-3600 = 46.52
-----------------------------------
Therefore the answer is choice C) $46.52
