Hi! Would you guys mind anderring this? A submarine is at a depth of 100 feet below sea level. Then it starts to dive at a rate
Vikentia [17]

Answer:

slope (m) = -50 or -50x

Step-by-step Explanation

I'm assuming that the x-axis is divided by 1 minute segments.

The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"

Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute

Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for

The tangent line to y= f(x) at (4,-6) passes through the point (10,9) Compute the following, f(4) and f'(4)
Anni [7]
The solution to your problem is as follows:

The tangent line passes through (4,-6), so x = 4 when y = -6 

=> f(4) = -6 

The tangent line will have a constant gradient. 

gradient is m = (-6 - 9)/(4 - 10) => 5/2

Equation is y - 9 = (5/2)(x - 10) 

=> y - 9 = (5/2)(x-10) 

<span>i.e. y = (5/2)(x-10) + 9 
</span>      y = (5/2)x - 25 + 9 =   y = (5/2)x - 16

Now, f '(x) = dy/dx = 5/2

so, f '(4) = 5/2....i.e. gradient is 5/2 whatever the value of x. 


I hope my answer has come to your help. Thank you for posting your question here in Brainly.
