10 dimes
The $2 are exchanged for 10 dimes and 4 quarters, which make 14 coins total.
Answer:
x =
25
/(1 − sin(y
)) and y ≠
π/2 +2πn
Step-by-step explanation:
Let's solve and simplify for x,
(x − 25
)/ x = sin(y)
Let's multiply both sides by x
((x − 25
)/x) *x= sin(y)*x
Then,
x − 25 = sin(y) * x
Let's add 25 to both sides
x − 25 + 25 = sin(y) * x + 25
If simplify again,
x = sin(y) * x + 25
Then we need subtract sin y x from both sides
x − sin(y) * x = sin (y)* x + 25 − sin (y)* x
It will equal:
x − sin (y)* x = 25
Factor x−sin(y) x: x(1−sin(y) ), then we get:
x (1 − sin(y)) = 25
Finally we need divide both sides by 1 − sin(y) ; y ≠π
/2
+ 2πn
And it will give us this equation:
x =
25
/(1 − sin(y
)) and y ≠
π/2 +2πn
Answer:
Length of Bar JK=l
Bar (JK) is dilated by a scale factor of n, having origin as the center of dilation.
New line segment formed named bar (J'K').
As given slope of bar(JK) =m
When we dilate a line segment with respect to origin , having origin as the center of dilation, there is no effect of slope on Dilation.
Length of bar (J'K')= (Length of bar JK)×(Scale factor)
= l×n Or n×l
Option (D) is correct.
