Answer:
Step-by-step explanation:
<u>Given</u>
- f(x)=2x-5
- g(x)=4x,
- f(g(3))= ?
<u>Solution:</u>
- g(3) = 4*3 = 12
- f(g(3)) = f(12) = 2*12 - 5 = 24 - 5= 19
Answer:
The sum of the first 51 terms of the sequence is 6018
Step-by-step explanation:
AP: −282,−266,−250,−234,...
First term = a = -282
Common difference = d = 
Common difference = d = -266-(-282)=-250-(-266)=16
Formula of sum of first n terms =
Substitute n = 51
So,

Hence the sum of the first 51 terms of the sequence is 6018
It is 225. Because you do the volume of one rectangular prism the equation is 15 x 3 x 3 which gives you 135. Then you do the volume of the other rectangular prism the equation is 10 x 3 x 3 which gives you 60. Then you add 135 + 90 that then gives you the total volume which is 225.
To solve for t, you must try to get it by itself. First, you have to subtract k from both sides.
c - k = rt + k - k
c - k = rt
Next, you have to divide r from both sides to find t.
I think the answer to this problem is b.
