The weight, in pounds, of a newborn baby t months after birth can be modeled by the equation W=10+2t What is the slope of the eq

Zanzabum

Answer:

m = 2

Step-by-step explanation:

W=10+2t has the form y = mx + b, the slope-intercept form. Comparing

y = b + mx to

w = 10 + 2t

we see that the slope, m, is 2. This signifies that the baby gains 2 pounds per month shortly after birth.

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

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

ΔABC has vertices A(0,10), B(4,10), and C(-2,4).

laiz [17]

A simple diagram will show you the intersection of altitudes is in the 2nd quadrant. It must have x-coordinate -2, as the altitude to the "base" y=10 must be the vertical line through (-2, 4).

The appropriate choice is ...

... C: (-2, 12)

CAN SOMEONE PLEASE ANSWER!

Andrew [12]

Hey there!!

Things to remember:

√ = something raised to the power 1/2

Given:

... √(10000x⁶⁴)

We can write this as:

... (√10000)×(√x⁶⁴)

The root of 10000 is 100

... 100×(x⁶⁴)¹/²

... 100 × x^64/2

... 100 × x^32

Hence, the answer is :

... <em>100x³² </em>

<em>Hope my answer helps!</em>
