How do I find the slope?
alex41 [277]

Answer:

Step-by-step explanation:

Find 2 points like (5,0) and (1,1) then use the rule y2- y1 over x2- x1 and replace the point (5,0) with x1 and y1 and the same way with the other point using x2 and y2 then solve your equation 1-5 over 1-0 calculate and this is the final answer

Find the line integral of f(x, y) = y e^X^2 along the curve r(t) = 3t i - 4t J, -2 lessthanorequalto t lessthanorequalto -1. The
Semenov [28]

\vec r(t)=3t\,\vec\imath-4t\,\vec\jmath

\implies\left\|\dfrac{\mathrm d\vec r(t)}{\mathrm dt}\right\|=\|3\,\vec\imath-4\,\vec\jmath\|=\sqrt{3^2+(-4)^2}=5

The line integral of f(x,y) along the curve C parameterized by \vec r(t) is

\displaystyle\int_Cf(x,y)\,\mathrm ds=\int_{-2}^{-1}f(3t,-4t)\left\|\dfrac{\mathrm d\vec r(t)}{\mathrm dt}\right\|\,\mathrm dt=-20\int_{-2}^{-1}te^{9t^2}\,\mathrm dt

Substitute u=9t^2 so that \mathrm du=18t\,\mathrm dt. Then

\displaystyle\int_Cf(x,y)\,\mathrm dS=-\frac{20}{18}\int_{36}^9e^u\,\mathrm du=\frac{10}9\int_9^{36}e^u\,\mathrm du=\boxed{\frac{10}9(e^{36}-e^9)}

Leviafan [203]
<span>A refrigerator contains 6 apples, 5 oranges, 10 bananas, 3 pears, 7 peaches, 11 plums, and 2 mangos. Imagine you stick your hand into the refrigerator and pull out a piece of fruit at random. What is the sample space for this process? a. S = {apple, orange, banana, pear, peach, plum, mango} b. S = {6, 5, 10, 3, 7, 11, 2} c. S = {6 apples, 5 oranges, 10 bananas, 3 pears, 7 peaches, 11 plums, 2 mangos}</span>

What is the point-slope form if it's through (1,4) and the slope is 3
Ratling [72]

For this case we have that by definition, the equation of the line of the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It's the slope

(x_ {0}, y_ {0}):It is a point through which the line passes

According to the given statement we have:

(x_ {0}, y_ {0}) :( 1,4)\\m = 3

Substituting we have:

y-4 = 3 (x-1)

Finally, the equation is:

y-4 = 3 (x-1)

Answer:

y-4 = 3 (x-1)
