Answer:
-1.596
Step-by-step explanation:
Apply log base 4 both sides
log4(4^(x+3)) = log4(7)
(x+3)log4(4) = lg7/lg4
x+3 = 1.403677461
x = -1.596322539
Answer:
48°
Step-by-step explanation:
Given the trigonometry equation
sin(52)= cos(5x-2)...1
According to the quadrant:
Sin(θ) = cos(90-θ)
Sin52 = cos(90-52)
Sin52 = cos48... 2
Substituting 2 into 1:
Cos48 = cos(5x-2)
48 = 5x-2
5x = 48+2
5x = 50
x = 10°
The smallest of the angle will be angle 5x-2 = 5(10)-2
= 50-2
= 48°
Whats the question i dont think u stated it
Answer:
|x-15|=0
Step-by-step explanation:
Obviously.
(x-4)•2 < 9
the difference between x and 4 means to subtract
and twice that means to double or times by 2
and all that’s LESS than 9
so the sign opens up towards the 9
