Answer:
90
Step-by-step explanation:
if 30 is one third then 30x3 will give us our answer,90.
The axis on symmetry is 3 the minimum is 9 and the y intercept it 9 if your teacher is talking about anything greater than or equal to 9 hope this helps god bless
Answer:
So 15^6 is the same thing as 15x15x15x15x15x15
and 15^9 is the same thing as 15x15x15x15x15x15x15x15x15
so the internet speed is 3 times greater
Step-by-step explanation:
Answer:
cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(2π/15)
Step-by-step explanation:
We will make use of trig identities to solve this. Here are some common trig identities.
Cos (A + B) = cosAcosB – sinAsinB
Cos (A – B) = cosAcosB + sinAsinB
Sin (A + B) = sinAcosB + sinBcosA
Sin (A – B) = sinAcosB – sinBcosA
Given cos(π/3)cos(π/5) + sin(π/3)sin(π/5) if we let A = π/3 and B = π/5, it reduces to
cosAcosB + sinAsinB and we know that
cosAcosB + sinAsinB = cos(A – B). Therefore,
cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(π/3 – π/5) = cos(2π/15)
