Answer:
each person gets 1/4
Step-by-step explanation:
Let ABC be a triangle in the 3rd quadrant, right-angled at B.
So, AB-> Perpendicular BC -> Base AC -> Hypotenuse.
Given: sinθ=-3/5 cosecθ=-5/3
According to Pythagorean theorem, square of the hypotenuse is equal to the sum of square of the other two sides.
Therefore in triangle ABC, 〖AC〗^2=〖AB〗^2+〖BC〗^2 ------
--(1)
Since sinθ=Perpendicular/Hypotenuse ,
AC=5 and AB=3
Substituting these values in equation (1)
〖BC〗^2=〖AC〗^2-〖AB〗^2
〖BC〗^2=5^2-3^2
〖BC〗^2=25-9
〖BC〗^2=16
BC=4 units
Since the triangle is in the 3rd quadrant, all trigonometric ratios, except tan
and cot are negative.
So,cosθ=Base/Hypotenuse Cosθ=-4/5
secθ=Hypotnuse/Base secθ=-5/4
tanθ=Perpendicular/Base tanθ=3/4
cotθ=Base/Perpendicular cotθ=4/3
If every 10 minutes 3 buses leave then over a course of 60 minutes (1 hour ) 18 buses would leave
Answer:
Step-by-step explanation:
(2-3)⁴ *4 - 9 + 3 = (-1)⁴ *4 - 9 + 3
= 1*4 - 9 +3
= 4 - 9 + 3
= - 5 + 3
= - 2
Answer:
D, 75.36 inches.
Step-by-step explanation:
The circumference of a circle is 2*pi*r, where pi=3.14
Using this, 2*3.14*12=75.36 inches.
