Write a linear equation. Explain it in number please! 20 points!!!

juin [17]

To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

(-6,12) and (-5,14)

Now let us find the slope of the linear line:

$m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6} = 2$

So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

let us use the point (-6,12) and the slope of 2

$y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4$

So the linear line is y = 2x + 4.

Hope that helps!

Consider f and c below. f(x, y) = (3 + 4xy2)i + 4x2yj, c is the arc of the hyperbola y = 1/x from (1, 1) to 3, 1 3 (a) find a fu

irga5000 [103]

We want to find a scalar function $f(x,y)$ such that $\nabla f(x,y)=\mathbf f(x,y)=\dfrac{\partial f}{\partial x}\,\mathbf i+\dfrac{\partial f}{\partial y}\,\mathbf j$ .
So we need to have
$\dfrac{\partial f}{\partial x}=3+4xy^2$
Integrating both sides with respect to $x$ gives
$f(x,y)=3x+2x^2y^2+g(y)$
Differentiating with respect to $y$ gives
$\dfrac{\partial f}{\partial y}=4x^2y+\dfrac{\mathrm dg}{\mathrm dy}=4x^2y$ $\implies\dfrac{\mathrm dg}{\mathrm dy}=0$ $\implies g(y)=C$
So we find that
$f(x,y)=3x+2x^2y^2+C$
By the fundamental theorem of calculus, we then know the line integral depends only on the values of $f(x,y)$ at the endpoints of the path. Therefore

$\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=f\left(3,\frac13\right)-f(1,1)=11-5=6$

Write 3^-4 as a fraction

Ad libitum [116K]

Answer: 1/3^4 or 1 over 3 fourths beacuse you need to just flip it to get the exponent to be positive. 3^-4 is basically 3^-4 over 1.

Select all ratios that are in their simplest form. a29:26 b4:28 c25:10 d28:5 e12:19

xxTIMURxx [149]

The correct answer is Option A , D , E.

<h3>What is meant by ratio?</h3>

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other.

<h3>What is meant by ratio in simplest form?</h3>

Ratio in it's simplest form means when the ratio can't be simplified anymore by cancelling out the common factors.

The ratio in Option(A) can't be simplified anymore because 29 is a prime number.

The ratio in Option(B) can be simplified to 1 / 7.

The ratio in Option(C) can be simplified to 5 / 2.

The ratio in Option(D) can't be simplified.

The ratio in Option(E) can't be simplified because 19 is prime number.

Hence, the correct answer is Option A , D , E.
