I explained it on your first question of help. It doesn't take very long to do, it's really simple. Like I said before, divide if it has a number on the front for example.. #11.... 6|x-1|=18.. Divide both sides by 6. Has to be the same number as the number on the front which in this case it is 6. Then you'll end up having |x-1|=3 and you solve it from there just like you did in #1
Answer:
Step-by-step explanation:
the expression will be
n-35
The answer is 1.171 x 10^183
So, here in part a), we are given n terms (no specific no. of terms given), so no. of terms = n , also, the common difference is defined as the difference between the next term to a specific term and the term, i.e , where d is the common difference, so here d = 49 - 45 = 4
Also, here the last term is 49 let say it the nth term, as no number of terms are given, so using the Arithmetic Progression formula, we can write as ;
Now, as we assumed there are n terms, so using the sum formula, we can have ;
Now, for part b) we are given a geometric progression with first term = a = 1, common ratio = r = (3/1) = 3, and no. of terms = n = 6, so now putting all values in the sum formula we will have;
The surface area of the cone is given by:
where r is the radius and L is slant height.
In this case r=5 and L=12. Then the surface area is:
Therefore the surface area is 267 squared centimeters,
