Anastasy [175]

Answer:

y=\frac{1}{3} x+4

Step-by-step explanation:

Slope-intercept from is:

y=mx+b

m is the slope and b is the y-intercept. Insert slope:

y=\frac{1}{3}x+b

The y-intercept is at point (0,4). The y-intercept is when x equals 0, so take the value of y and insert into the equation:

y=\frac{1}{3} x+4

Finito.

|-19+9|/3-|14-22|/9<br> give me an answer
MArishka [77]

Answer:22/

9

= 2 4/

9

≅ 2.4444444

Step-by-step explanation:

Add: -19 + 9 = -10

Absolute value: abs(the result of step No. 1) = abs(-10) = 10

Divide: the result of step No. 2 / 3 = 10 / 3 = 3.3333333333333 = 10/

3

Subtract: 14 - 22 = -8

Absolute value: abs(the result of step No. 4) = abs(-8) = 8

Divide: the result of step No. 5 / 9 = 8 / 9 = 0.88888888888889 = 8/

9

Subtract: the result of step No. 3 - the result of step No. 6 = 10/

3

- 8/

9

= 10 · 3/

3 · 3

- 8/

9

= 30/

9

- 8/

9

= 30 - 8/

9

= 22/

Find dy/dx any one <br>x=acost , y=asint​
dangina [55]

Answer:

x=a \cos t \implies \dfrac{dx}{dt}=-a \sin t

y= a \sin t \implies \dfrac{dy}{dt}=a \cos t

Using the chain rule:

\begin{aligned}\implies \dfrac{dy}{dx} & =\dfrac{dy}{dt} \times \dfrac{dt}{dx}\\\\& = a \cos t \times \dfrac{1}{-a \sin t}\\\\& = \dfrac{a \cos t}{-a \sin t}\\\\& = - \dfrac{\cos t}{\sin t}\\\\& = - \cot t\end{aligned}
