Yes that’s true. You got that correct everyone listen to them.
Answer:
39.9
Step-by-step explanation:
a/sinA = c/sinC
a/sin(77) = 16/sin(23)
a = sin(77) × 16/sin(23)
a = 39.89935764
It's the same formula as the one used on Earth. It is based on the Pythagorean theorem.
length = √((∆x)^2 +(∆y)^2 +(∆z)^2)
.. where ∆x, ∆y, ∆z are the differences between the end-point coordinates in the x-, y-, and z-directions, respectively.
8x.65= 5.2 I haven’t learned this but I’m trying my best to or maybe it will be 8+.65 which will be 8.65 which is close to 9
-3x^4 + 27x^2 + 1200 = 0
factor out -3
-3(x^4 -9x^2 -400)=0
divide by -3
x^4 -9x^2 -400=0
(x^2-25) (x^+16) = 0
x^2-25=0 x^2+16=0
(x-5)(x+5)=0 x^2=-16
x=5 x=-5 x = 4i x=-4i
Answer: x=5 x=-5 x = 4i x=-4i
