The average number of red blue and green bags is 136. They are 30 more red than blue bags. There are 15 less green than blue. Ho

Andrews [41]

Answer:

The Number of green bag is 116

Step-by-step explanation:

Given as :

The average number of red , blue and green bags = 136

I.e $\frac{red + blue + green}{3}$ = 136

Or, red + blue + green = 136 × 3

Or, red + blue + green = 408

Number of red bag = Number of blue bags + 30

Number of green bag = Number of blue bags - 15

Or, ( blue bag + 30 ) + blue bag + ( blue bag - 15 ) = 408

Or, 3 blue bag = 408 - 15

Or, Number of blue bags = 131

Number of red bag = Number of blue bags + 30

Number of red bag = 131 + 30

Or, Number of red bag = 161

Number of green bag = Number of blue bags - 15

Or, Number of green bag = 131 - 15

Or, Number of green bag = 116

Hence The Number of green bag is 116 Answer

g For the curve parameterized by x(t) = 3 sin t, y(t) = 5 cost, for −π/4 ≤ t ≤ π/2: (a) Sketch the curve and the direction trace

tamaranim1 [39]

Answer:

a) See the file below, b) $s = \int\limits^{0.5\pi}_{-0.25\pi} {[\left( 3\cdot \cos t\right)^{2}+\left(-5\cdot \sin t \right)^{2}]} \, dx$ , c) $s \approx 9.715$

Step-by-step explanation:

a) Points moves clockwise as t increases. See the curve in the file attached below. The parametric equations describe an ellipse.

b) The arc length formula is:

$s = \int\limits^{0.5\pi}_{-0.25\pi} {[\left( 3\cdot \cos t\right)^{2}+\left(-5\cdot \sin t \right)^{2}]} \, dx$

c) The perimeter of that arc is approximately:

$s \approx (\frac{1}{4} + \frac{1}{8})\cdot 2 \pi\cdot \sqrt{\frac{3^{2}+5^{2}}{2} }$

$s \approx 9.715$

Expanding using the distributive property, we get (x-5)*(x-5)=x^2-5x-5x+25=x^2-10x+25. Multiplying that by -6, we get -6x^2+60x-150 . We then add 12 at the end to get -6x^2+60x-138. Using the quadratic formula (since we want the function to equal 0 to find the zeros), we get x=(-60+-sqrt(3600-3312))/(-6*2)=(-60+-sqrt(288))/-12. For sqrt(288), since 12^2=144 and 144*2=288, we can rewrite it as 12*sqrt(2). Putting that back in, we get
(-60+-(12*sqrt(2))/-12. Factoring it out, we get -5+-sqrt(2)=-5+sqrt(2) or -5-sqrt(2) which is C
