Answer:
Step-by-step explanation:
Sin(30o) = 0.5 or 1/2
Sin(60o) = sqrt(3)/2
So the statement is false
Answer:
equation;

Center (-4,2)
Radius is

Step-by-step explanation:
Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of

Where (h,k) is center
r is the radius
So first we group like Terms together

Add 7 to both sides


Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem

and

so we have



To find our center, h is -4 and k is 2
so the center is (-4,2)
The radius is

So the radius is 3 times sqr root of 3.
Answer:
D/0
Step-by-step explanation:
the domain of (g o f )(x) is "all x > 0".

By taking <span>logarithmic of base 10
∴ </span><span>

∴ x log 4 = log 64
∴

note: we don't need to write the base in case of the base =10
∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>
