Cotangent is one over tangent
1/(4/7)
Answer 7/4
Answer:
The smallest nonzero whole number that is divisible by 315,378 & 392 is the LCM of these 3 numbers. This can be found out by factorization method. Thus,the smallest nonzero whole number that is divisible by 315,378 & 392 is 52,920.
A) x^2 + y^2 = 80
B) x * y = 12
What is x^2 -y^2?
B) x * y = 12
So y = 12 / x
A) x^2 + (12/x)^2 = 80
x^2 + (12/x)^2 = 80
x^2 + (144/x^2) = 80
Multiplying each side by x^2
x^4 + 144 = 80x^2
x^4 -80x^2 + 144 = 0

Answer:
Step-by-step explanation:
(distance) d = (speed) s * t (time)
= 55km/h * 12.30m/s
= 11.275 km
= 11.275 * 1000
= 11275m
0.225, 23%, 1/4
Step my step
23% = 0.23
1/4 = 0.25
