Answer:
19m - 10
Step-by-step explanation:
Order of Operation: BPEMDAS
Step 1: Write out equation
5(3m - 2) + 4m
Step 2: Distribute parenthesis
15m - 10 + 4m
Step 3: Combine like terms
19m - 10
The maximum number of minutes she could use her phone is 150
Hello,
Since 3sin x-4sin^3x=sin (3x) (*****)
3sin x-4sin^3x=-1
==>sin (3x)=-1
==>3x=3π/2 +2kπ
==>x=π/2+2kπ/3, k being an integer
(*****)
sin (3x)=sin(x+2x)=sin x cos2x+cos x sin 2x
=sin x(cos²x-sin²x)+2cos²x sin x
=sin x(cos²x+2cos²x-sin²x)
=sinx(3(1-sin²x)-sin²x)
=3sin x-4sin^3x
Answer:
(0,0)
Step-by-step explanation:
Answer:
AB = 4
Step-by-step explanation:
Calculate AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(0, 10)
AB = 
= 
= 
=
= 4
