Answer:
A
Step-by-step explanation:
Using the Sine rule in Δ ABC
=
, substitute values
=
( cross- multiply )
BC sin38° = 3 sin66° ( divide both sides by sin38° )
BC =
→ A
The standard equation of the circle is:
(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...
so
30.
(x-2)^2+(y-7)^2=16
31.
We need to find the radius...(I'll just use the Pythagorean Theorem)
r^2=6^2+8^2
r^2=36+64
r^2=100 (so the radius is 10) and its center is (-6,-8) so
(x+6)^2+(y+8)^2=100
Answer:
Step-by-step explanation:
The function f(x) represents the amount of money in dollars Raul earns per ticket, where x is the number of tickets he sells. This is represented by the function,
f(x) = 3x2 + 16 - - - - - - -1
The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. The function is represented by
g(x) = the square root of five times x cubed
g(x) = √(5x^3)
To find f(g(x)), we substitute g(x) into f(x).
f(g(x))= 3[√(5x^3)]^2 + 16
