Find the points on the curve where the tangent is horizontal or vertical. If you have a graphing device, graph the curve to chec

klasskru [66]

Answer:

There is a horizontal tangent at (0,-4)

The tangent is vertical at (-2,-3) and (2,-3).

Step-by-step explanation:

The given function is defined parametrically by the equations:

$x=t^3-3t$

and

$y=t^2-4$

The tangent function is given by:

$\frac{dy}{dx}=\frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

$\implies \frac{dy}{dx}=\frac{2t}{3t^2-3}$

The tangent is vertical at when $\frac{dx}{dt}=0$

$\implies \frac{3t^2-3}{2t}=0$

$\implies 3t^2-3=0$

$\implies 3t^2=3$

$\implies t^2=1$

$\implies t=\pm1$

When t=1,

$x=1^3-3(1)=-2$ and $y=1^2-4=-3$

When t=-1,

$x=(-1)^3-3(-1)=2$ and $y=(-1)^2-4=-3$

The tangent is vertical at (-2,-3) and (2,-3).

The tangent is horizontal, when $\frac{dy}{dx}=0$ or $\frac{dy}{dt}=0$

$\implies 2t=0$

$\implies t=0$

When t=0,

$x=0^3-3(0)=0$ and $y=0^2-4=-4$

There is a horizontal tangent at (0,-4)

Answer this question correctly please and then I’ll mark you as a brainliest!

Studentka2010 [4]

Answer:

Step-by-step explanation:

1) 2 - (- 8) = 2 + 8 = 10

2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5

3) We can find the common denominators through the least common multiple between the denominators:

4,12 | 2

2, 6 | 2

1, 3 | 3

1, 1 (2 × 2 × 3 = 12)

Then, 12 is the least common denominator.

4) 8 (1/4) + 10 (2/5) + 7 (5/8)

8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4

10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5

7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8

+ 8/8 + 8/8 + 5/8 = 61/8

33/4 + 52/5 + 61/8

Employing the least common denominator:

4, 5, 8 | 2

2, 5, 4 | 2

1, 5, 2 | 2

1, 5, 1 | 5

1, 1, 1 (2 × 2 × 2 × 5 = 40)

(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40

330/40 + 416/40 + 305/40

1051/40

Solve the equation for x by graphing -4x+1=3x-4 A x=0.75 B x=0 C x=-0.75 D x=-1.75

fiasKO [112]

Answer:

Step-by-step explanation:

-4x + 1 = 3x - 4 subtract 1 from both sides

-4x = 3x - 5 subtract 3x from both sides

-7x = -5 divide both sides by (-7)

x = 5/7
