Answer:
24 cars
Step-by-step explanation:
Given
Required
Determine the number of red cars
Number of red cars is calculated using:
20 quilts x £550 each = £11,000
35 quilts x £400 each = £14,000
£14,000 - £11,000 = £3,000
Shirley will make £3,000 more in revenue if she makes the change.
Hope this helps
Answer:
Hey mate.....
Step-by-step explanation:
This is ur answer....
<h3>Triangle fixed value = 180</h3>
<em>= 180 - (112 + 47)</em>
<em>= 180 - 159</em>
<em>= <u>21</u></em>

Answer:
see below
Step-by-step explanation:
y' = -2e⁻ˣcos(x) -sin(x)2e⁻ˣ +e⁻ˣsin(x)-cos(x)e⁻ˣ = e⁻ˣ(-2cos(x)-2sin(x)+sin(x) -cos(x))
=e⁻ˣ(-3cos(x)-sin(x))
y'' = -e⁻ˣ(-3cos(x)-sin(x)) + (3sin(x)-cos(x))e⁻ˣ
y'' = e⁻ˣ[3cos(x)+sin(x) + 3sin(x)-cos(x)] = e⁻ˣ[2cos(x)+4sin(x)]
y''+2y'+2y = 0
e⁻ˣ[2cos(x)+4sin(x)] + 2[e⁻ˣ(-3cosx-sinx)] + 2[2e⁻ˣ cos(x)−e⁻ˣ sin(x)]
e⁻ˣ[2cos(x)+4sin(x)-6cos(x)-2sin(x)+4cos(x)-2sin(x)]
e⁻ˣ[-4cos(x)+2sin(x)+4cos(x)-2sin(x)]
e⁻ˣ[0cos(x)+0sin(x)] = 0
