=[(sinx/cosx)/(1+1/cosx)] + [(1+1/cosx)/(sinx/cosx)]
=[(sinx/cosx)/(cosx+1/cosx)]+[(cosx+1/cosx)/(sinx/cosx)]
= [sinx/(cosx+1)] + [(cosx+1)/sinx]
= [sin^2x+(cosx+1)^2] / [sinx (cosx+1)]
= [2+2cosx] / [sinx(cosx+1)]
=[2(cosx+1)] / [sinx (cosx+1)]
= 2/sinx
= 2 cscx
(I think this will be helpful for you. if you can see the picture, it has more detail in it.)
from the question, (-2,2) and (1,2) have the same y value so you can use that as your base and easily find the perpendicular height using the y axis since it's parallel to the x axis.
the third point, (0,-6), to the base is your height
use the sum of the positive of the y values to find your height (because height can't be negative): 6+2 = 8
area of a triangle = 1/2 bh = 1/2 x 3 x 8 = 12
Note: 1/2 bh only works because (-2,2) and (1,2) form a line parallel to the x axis
12 is the median
Q1 is 12.5
Q3 is 9.5
The answer is 9.5
Hope this helps!
Sean was dividing 0.45 by 0.75.According to the given choices, which one will be correct. First, let us solve the given division problem:
=> 0.45 / 0.75 = 0.6 is the quotient. Thus the answer would be:
B.
It will be greater than 0.45.
Answer:
Hope it helps u
Step-by-step explanation:
3/4x + 2 = 3/8x - 4
subtract 2 from both sides we get
(3/4)x=(3/8)x-6
subtract (3/8)x from both sides, we get
(3/4)x-(3/8)x= -6
now taking L.C.M we get
((6-3)/8)x= -6
(3/8)x= -6
x= -6*8/3
<h2>
x= -16</h2>
