Answer:

3rd and 4th option

Step-by-step explanation:

-1 times -1 is 1 and multiply that by another -1 and you get -1

-1 times -1 is 1 and you do that twice in the last option so that would be 1 and then multiply that by-1 and you get -1.

Elena L [17]

Answer:

B

Step-by-step explanation:

5×sqrt(8)×3×sqrt(4) = 15×sqrt(8)×sqrt(4) = 15×sqrt(8)×2 =

= 30×sqrt(8) = 30×sqrt(4×2) =

= 30×2×sqrt(2) = 60×sqrt(2)

Determine an equation of the tangent line to <br> y = e - 2x<br> at the point (0,1).
Darya [45]

Answer:

y=-2x+1

this is the equation of the tangent line to the curve at the point (0,1)

Step-by-step explanation:

y = e^{-2x}

to find the tangent line we need to find the curve's derivative. using \dfrac{d}{dx}e^{ax} = ae^{ax}, we'll find dy/dx.

\dfrac{dy}{dx} = -2e^{-2x}

^ this is the equation of the slope of the curve. By finding the slope of the curve at (0,1) we'll also be finding the slope of the tangent to the curve at (0,1).

at (0,1) x = 0. we'll use that in dy/dx

\dfrac{dy}{dx} = -2e^{-2(0)}

\dfrac{dy}{dx} = -2(1)

\dfrac{dy}{dx} = -2

this is the slope of the tangent at point (0,1)

we'll use the general equation of the line formula to find the equation of tangent.

(y-y_1)=m(x-x_1)

here m is the slope, i.e. m = -2, and (x1,y1)=(0,1)

(y-1)=-2(x-0)

y=-2x+1

this is the equation of the tangent line at the point (0,1)
