85? I multiplied seven times seven the three times four then divided it by three then timed it by nine I Don’t know if this is correct tho
Answer:
d = 14/5
Step-by-step explanation:
The point (-4,2) means that;
At x = -4, y = 2
Now general form of a linear equation is;
Ax + By + C = 0
We are given;
4y = 3x + 6
Rearranging to the form of a linear equation gives;
3x - 4y + 6 = 0
Thus, A = 3, B = -4 and C = 6
Thus, at point (-4,2), distance between them is;
d = (3(-4) - 4(2) + 6)/√(3² + (-4)²)
d = -14/5
We will take the absolute value.
Thus; d = 14/5
Answer:
5/6
Step-by-step explanation:
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
Hi there!
• g(x) = 6x - 3
Then,
if g(x) = y :-
y = 6x - 3
⇒6x = y + 3
⇒x =
According to th' question :-
g⁻¹(x) =
g⁻¹(9) =
g⁻¹(9) =
g⁻¹(9) = 2
Hence,
The required answer is g⁻¹(9) = 2
~ Hope it helps!
