0.75 x 14 = 10.50
15 - 10.50 = 4.50
your answer is : Sharon will receive $4.50 change
Answer is: 2x=12, 14, 16, and 18
T=(60cos78, 60sin78)
T=(12.47, 58.69)
C=45
d=√((45-12.47)^2+58.69^2)
d≈67.1km
U = (-2,3)
V = (3,0)
midpoint of UV
= ( (3-2)/2 , (3+0)/2 )
= ( 1/2 , 3/2)
= ( 0.5 , 1.5)
X = (0.5 , 1.5) [from fig]
midpoint of UV = X
W= (-2,-3)
V =( 3.0)
Y = ( (-2+3)/2 , (-3+0)/2 )
= (0.5 , - 1.5)
Y = ( 0.5 , -1.5) [ from fig ]
Y is the midpoint of WV
by midpoint theorem ,
UW = 2( XY )
One interpretation of your intent would be as follows:
16x^11y^8
Find 4 √ [-----------------]. Is that what you meant?
81x^7y^6
4*x^5*√x*y^4
If so, then the correct result would be 4 ---------------------
9*x^3*√x*y^3
and this could be reduced to:
4*x^5 * y^4 * √(x) 4*x^2*y
4 --------------------------- = -------------
9*x^3*y^3 √(x) 9
