Find parametric equations for the tangent line at the point (cos(3pi/6),sin(3pi/6), (3pi/6))
r-ruslan [8.4K]
r(t)=(\cos{t},\sin{t},t)
\\r'(t)=(-\sin{t},\cos{t},1)
\\t= \frac{3\pi}{6} = \frac{\pi}{2}
\\ r'(t)=(-\sin{\frac{\pi}{2}},\cos{\frac{\pi}{2}},1)

Which point satisfies both ƒ(x) = 2x and g(x) = 3x?
Dvinal [7]
Ƒ(x) = 2x and g(x) = 3x?

The question means at which points (or coordinates)  f(x) & g(x) intercepts.
In this case you proceed as follows:
f(x) =g(x)==> 2x = 3x or 0 = x if x = 0 , y also =0 then both graphes passes through the origin O (0,0)

In a swimming competition, Grace jumped from the height of 22 meters. The following table represents the height f (t), in meters
exis [7]

For this case we have the following variables:

t: time in seconds.

f (t): height as a function of time.

By the time Grace reaches the pool, the height is equal to zero.

We have the following table:

Time (t) (in seconds) Height f(t) (in meters)

          1                                   25

          2                                  20

          3                                   15

          4                                   0

We observe that the height is equal to zero after 4 seconds.

Equivalently:

f (4) = 0

Answer:

the following represents the x-intercept of f(t):

Grace reaches the swimming pool after 4 seconds

Write an equation of the line that passes through the point (6, -9) with the given slope m = 3.
adelina 88 [10]

Answer:

y = 3x - 27

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (6, - 9) into the partial equation

- 9 = 18 + c ⇒ c = - 9 - 18 = - 27

y = 3x - 27 ← equation of line
