x = 64
Step-by-step explanation:
" the sum " means add
n + 14 = 72 <== ur eqiation
This is the input/output table for a linear function. Linear functions increase or decrease by a constant value (the slope).
(38 - 19) / (2 -1) = 19
See how every output is +19 the one before it?
then the output following 57 is 57+19 = 76
1 is one 19
2 is two 19's
3 is three 19's
n is 19n
Correct option is D) -0.6.
<u>Step-by-step explanation:</u>
We have
. Also, we know that
. Let's find out value of
using above formula:

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
But we know that cos
is negative in third quadrant , Therefore
.
Hence, correct option is D) -0.6.
Whatever decimals you choose, b HAS to be greater than a. It can't be the other way around where a is greater. So a possible answer could be, b=0.9 and a=0.3
