To solve this problem you must apply the proccedure shown below:
 1. You have the following parametric equations given in the problem above: 
<span> x=e^3t
 y=e^-t</span> 
 2. Therefore, you must solve fot et in the second equation, as below:
 y=e^-t
 y=1/e^t
 e^t=1/y
 3.Substitute into the first equation:
 x=e^3t
 x=(e^t)^3
 x=(1/y)^3
 x=1/y^3   (y>0)
 The answer is: x=1/y^3  (y>0)

Pleaseeee help! I'm really confused.

He will be making a right triangle with the legs being 24 x 45. The diagonal will be the hypotenuse of the triangle. To find the amount of fencing we need the perimeter of the triangle.
Use Pythagorean theorem to find the length of the hypotenuse.
a^2 + b^2 = c^2
24^2 + 45^2 = c^2
576 + 2025 = c^2
2601 = c^2
sqrt 2601 = c
c = 51
Adding the three lengths the total fencing needed is
51+24+45=120 meters

Find the value of k such that lim--&gt;4 (x^2+x-k)/(x-4) exists
7nadin3 [17]

Answer:

k=20

Step-by-step explanation:

when x approaches 4, the denominator x-4 approaches 0

if the denominator is 0, it means that this is invalid

if the function is a number over 0 when x=4, it represents a vertical asymptote, which means no limit

so the only way possible to let there be a limit is to let the function be 0/0 when we plug in x=4

so x^2 + x - k = 0 when x = 4

4^2 + 4 - k = 0 ==> 20 - k = 0 ==> k = 20

Find the slope-intercept equation of the line containing (2, -3) and having slope m=4
Inessa [10]

Answer: y = 4x - 11

Step-by-step explanation:

m = 4 , ( 2,-3 )

y - y1 = m ( x - x1 )

y - (-3) = 4( x - 2 )

y + 3 = 4x - 8

y = 4x - 11
