Set up a porportion,
3/5 hours / 2/5 square yards
1 hour / x square yards
simplify by cross multiplying
3/5x <span>= 2/5(1).
</span>3/5x <span>= 2/5.
</span> 3/5/3/5x = <span>2/5/3/5
x </span><span>= 10/15
</span>x <span>= 2/3
</span><span>
so she can paint </span><span>2/3 square yards in 1 hour. hope this helps!</span><span>

The Taylor Series expansion of f(x) = sin(x) about a = π i given by

where the c's are contants.
That is
f(x) = c₀ + c₁(x-π) +c (x-π)² + c₃ (x-π)³ + ...,
₂
The first few derivatives of f(x) are
f' = c₁
f'' = 2c₂ = 2! c₂
f''' = 3.2c₃ = 3! c₃
f⁽⁴⁾ = 4.3.2c₄ = 4! c₄
and so on.
The pattern indicates that

The derivatives of f(x) are
f' = cos(x)
f'' = -sin(x)
f''' = -cos(x)
f⁽⁴⁾ = sin(x(
and so on
The pattern indicates that
f⁽ⁿ⁾(x) = cos(x), n=1,5,9, ...,
= -sin(x), n=2,6,10, ...,
= -cos(x), n=3,7,11, ...,
= sin(x), n=4,8,12, ...,
The radius of convergence is |x-π|<1 by the ratio test.
Yes it is a rational number
Answer:
is there a graph
Step-by-step explanation:
Answer:
pen = 12
book = 24
Step-by-step explanation:
x = cost of pen
2x + x = 36
3x = 36
x = 12
pen = 12
book = 24
