Answer:
(h o g)(5) = 20
Step-by-step explanation:
(h o g)(5) = h(g(5)) <em>This is two ways of writing the expression</em>
g(x) =
h(x) = 3x + 5 <em>g(x) and h(x) are your "plug-ins" for the expression</em>
g(5) =
=
= 5 <em>This is how you would solve for plugging in 5 to g(x)</em>
<em>Whatever you get for g(5) {the answer to it} is what you will be plugging into h(x); x being equal to g(5).</em>
h(5) = 3(5) + 5 = 15 + 5 = 20
1st way
To solve this we need to know ratio.

Now we can see that odd numbers of geometric sequence are positive and even numbers are negative. 91 - odd number, so it will be positive. If ratio is equal to -1, than 91st number is

2nd way
Firstly, we need to find ratio.

Secondly, we need to use this formula


First Equation:
0.6 +(0.4+0.9) =n
Step 1: do parentheses first:
0.4+0.9 = 1.3
Step 2: Add 0.6 + 1.3
0.6 + 1.3 = 1.9
n= 1.9
Second Equation:
(1.57 + 0.75) + 0.25 + n
Step 1: do parentheses first:
1.57 + 0.75 = 2.50
Step 2: Add 2.50 + 0.25 = 2.75
Step 3: Add 2.75 and n = 2.75+n
Final Answer:
1.9 +2.75+n = 4.65 +n
