When you have a fraction to a negative power, you flip the number over, and then act like it's to the positive power. So this equals.
. Now you simply have to evaluate
, which is 4.
C. 4 (not to be confused with the explosive... :P)
Answer:
x = 40
y= 20
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = 20 sqrt(3)/ x
x sin 60 = 20 sqrt(3)
x = 20 sqrt(3)/ sin 60
x = 20 sqrt(3)/ sqrt(3)/2
x = 20 *2
x = 40
tan theta = opp /adj
tan 60 = 20 sqrt(3)/y
y = 20 sqrt(3)/ tan 60
y = 20 sqrt(3) / sqrt(3)
y = 20
Answer:
AB=(-0.5 , 0)
Step-by-step explanation:
Given point
A = (-3,-5)
B = (2,5)
AB = {(x1+x2)/2 , (y1+y2)/2}
AB = {(-3+2)/2 , (-5+5)/2}
AB = (-0.5 , 0)
Answer:
y=40/183x
Step-by-step explanation:
y = Rise/Run multiplied plus y intercept by x or Y= mx + b
There is no b
m = 40/183
Y = 40/183x
