Re write it in so that to have one single entity on the left & same on the right
log(x-1)-log5 = log[(x-1)/5]
and log(x+1)-logx = log[(x+1)/x]
So:
log[(x-1)/5] = log[(x+1)/x] ==> (x-1)/5 = (x+1)/x
Now you can solve it: x(x-1)=5(x+1)
==> x² - 6x -5 =0
Solving this quadratic equation gives x'=3+√14 & x" =3-√14
480 cm = 4.8 m
You solve this by dividing the length value by 100!
The answer would be A or 2 square root of 6 + 4!! Hope that helped please give me 5 stars and a thanks! Thanks so much ! Do well on your test!
Answer:
V = 1020.5 yd³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h( r is the radius and h the height )
Here r = 5 and h = 13 , then
V = π × 5² × 13
= 3.14 × 25 × 13
= 1020.5 yd³
To subtract these two numbers, I will convert them into decimal form to make it much easier.
16 1/8 = 16.125
5 3/4 = 5.75.
Now that we have them in decimal form, we can subtract!
16.125 - 5.75 = 10.375
10.375 put into fraction form is 10 3/8.
A.) Matches 10 3/8, so A is your answer.
I hope this helps!
