Answer:
angle B = 33.42
Step-by-step explanation:
take angle B as reference angle
using tan rule
tan B = opposite/adjacent
tan B = 6/9
tan B = 0.66
B = 
B = 33.424
B = 33.42
Answer:
Both sides must remain equal.
Step-by-step explanation:
An equation features an equal sign in the middle, therefore showing that both sides are always equal to each other. That is why the answer is equal.
Answer:
What this is is factoring and these are both perfect squares.
(3x-5)(3x+5) is the answer.
Step-by-step explanation:
First we take the 9x^2-25 and split in in two statements
(3x-5) (3x+5)
then foil to check it
first side: 3x*3x=9x^2
outside: 3x*5=15x
inside: -5*3x=-15x
last: -5*5=-25
then put it together
9x^2+15x-15x-25
the 15x and -15x cancel each other out so you're left with 9x^2-25
Looks like the starting series is
Note the degree of the first few terms in the series, for 
, are 
, and so on.
So if the series were to start at 
, we would need to preserve that pattern, and we do that by replacing 
with 
:
Simplifying a bit, we end up with
Answer:
negative
Step-by-step explanation:
positive -> as x increases, y increases
negative -> as x increases, y decreases
