Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h

Step-by-step explanation:

Lets assume Malcolm maximum speed to be M km/h and Ravi maximum speed to be R km/h

Average of their maximum speed is; (M+R)/2 =260 km/h

This can be simplified to M+R= 260*2

M+R = 520.......................................(I)

When Malcolm's speed is doubled,

2M=R+80 km/h ----------------------(ii)

The two equations are;

M+R = 520 ------ M=520-R ----(i)

2M=R+80 ---------------------------(ii)

Replacing M with (i) above

2M=R+80

2(520-R) =R+80

1040 -2R =R+80

1040-80 = R+2R

960 = 3R

960/3 =R

320 =R

M+R =520

M=520-320 =200

Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h

Solve: (3x^2-y)dx + (4y^3-x)dy =0 and find the solution passing through (1,1).

nordsb [41]

Step-by-step explanation:

The given equation is

$(3x^{2}-y)dx+(4y^{3}-x)dy=0\\M(x,y)dx+N(x,y)dy=0$

As a check for exactness we have

$\frac{\partial N}{\partial x}=\frac{\partial M}{\partial y}\\\\\therefore \frac{\partial N}{\partial x}=\frac{\partial (4y^{3}-x)}{\partial x} =-1\\\\\frac{\partial M}{\partial y}=\frac{\partial (3x^{3}-y)}{\partial y} =-1\\\\\therefore \frac{\partial N}{\partial x}=\frac{\partial M}{\partial y}=-1$

Hence the given equation is an exact differential equation and thus the solution is given by

thus the solution is given by

$u(x,y)=\int M(x,y)\partial x+\phi (y)\\\\u(x,y)=\int (3x^{2}-y)\partial x+\phi (y,c)\\\\u(x,y)=x^{3}-xy+\phi (y,c)\\\\$

Similarly we have

$u(x,y)=\int N(x,y)\partial y+\phi (x,c)\\\\u(x,y)=\int (4y^{3}-x)\partial y+\phi (x,c)\\\\u(x,y)=y^{4}-xy+\phi (x,c)\\\\$

Comparing both the solutions we infer

$\phi (x,c)=x^{3}+c$

Hence the solution becomes

$u(x,y)=x^{3}+y^{4}-xy=c$

given boundary condition is that it passes through (1,1) hence

$1^{3}+1^{4}-1=c\\\\\therefore c=1$

thus solution is

$u(x,y)=x^{3}+y^{4}-xy=1$

What is the value of h for the parallelogram?

anastassius [24]

Answer:

9.6 units

Step-by-step explanation:

The area of the parallelogram is the product of the base length and distance between parallel sides, either way you figure it.

16 × 6 = area = 10 × h

96 = 10h

h = 96/10 = 9.6 . . . . units

PLEASE PLEASE HELP!! ITS JUST 2 QUESTIONS ! FOR 15 POINTS BE HONEST WITH YOUR ANSWER!!

GaryK [48]

1. Two angles are complementary. One angle measures 50°. What is the measure of the other angle?
complementary, sum of the angles = 90

so 90 - 50 = 40

answer is
C.40°

2.Two angles are supplementary. One angle measurement is 30° more than the other. What is the measure of the smaller angle?

supplementary, sum of the angles = 180

One angle measurement is 30° more than the other.
so both angles are 75 and 105

105 is 30 more than the other angel of 75

answer
measure of the smaller angle is 75

so it's D.75°
