Answer:
{-29/4, -19/2, -47/4}
Step-by-step explanation:
Note that this is a decreasing arith. seq. Each term is smaller than the previous term, the result of the subtraction of 2 1/4 (equivalent to 9/4).
The fourth term is -11/4; subtracting 9/4 results in -20/4, or -5.
The fifth term is -20/4; subtracting 9/4 results in -29/4.
The 6th term is -29/4; subtracting 9/4 results in -38/4, or -19/2.
The 7th term is -38/4; subtracting 9/4 results in -47/4.
Thus, the "next three terms" following the first four terms are {-29/4, -19/2, -47/4}
X=80°
A triangle’s angle measurements always add up to 180°. So 180-70-30=80
Any number bigger than 3
4,5,6,7 are 4 numbers
Answer:
(r o g)(2) = 4
(q o r)(2) = 14
Step-by-step explanation:
Given


Solving (a): (r o q)(2)
In function:
(r o g)(x) = r(g(x))
So, first we calculate g(2)




Next, we calculate r(g(2))
Substitute 9 for g(2)in r(g(2))
r(q(2)) = r(9)
This gives:


{

Hence:
(r o g)(2) = 4
Solving (b): (q o r)(2)
So, first we calculate r(2)




Next, we calculate g(r(2))
Substitute 3 for r(2)in g(r(2))
g(r(2)) = g(3)




Hence:
(q o r)(2) = 14
