Answer:
a = 64
Step-by-step explanation:
The geometric mean of 2 numbers a and b is , then
= 16 ( square both sides )
28a = (16 )² = 1792 ( divide both sides by 28 )
a = 64
Y=3x/4-6
doing this is thinking of it in a matter of geometric figure and how you would plot it on a graph and this is the only way it would look write.
Answer:
VERY HARD QUESTIONS SO I WILL TELL YOU LATER
Answer:
Step-by-step explanation:
step 1
Find the
we know that
Applying the trigonometric identity
we have
substitute
Remember that
π≤θ≤3π/2
so
Angle θ belong to the III Quadrant
That means ----> The sin(θ) is negative
step 2
Find the sec(β)
Applying the trigonometric identity
we have
substitute
we know
0≤β≤π/2 ----> II Quadrant
so
sec(β), sin(β) and cos(β) are positive
Remember that
therefore
step 3
Find the sin(β)
we know that
we have
substitute
therefore
step 4
Find sin(θ+β)
we know that
so
In this problem
we have
substitute the given values in the formula
