The position of an object at time t is given by s(t) = 1 - 12t. Find the instantaneous velocity at t = 2 by finding the derivati

Nostrana [21]

s(t) = 1 - 12t
s'(t)= -12

As you can see the derivative is a constant, this is because the function is linear.
The velocity of a linear function is constant so at t=2 it is -12. (at any t would be the same)

Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).

o-na [289]

Answer:

Option A) y = -2x + 15

Step-by-step explanation:

step 1

Find the slope of the line perpendicular to the given line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

The equation of the given line is

$y=\frac{1}{2}x+3$

The slope of the given line is $m=\frac{1}{2}$

therefore

The slope of the line perpendicular to the given line is

$m=-2$

step 2

Find the equation of the perpendicular line in point slope form

$y-y1=m(x-x1)$

we have

$m=-2$

$point\ (10,-5)$

substitute

$y+5=-2(x-10)$ ---> equation in point slope form

Convert to slope intercept form

$y=mx+b$

$y+5=-2x+20$

$y=-2x+20-5$

$y=-2x+15$

The record high temperature in Alabama is 112f and the record low temperature is -27f. What is the difference between the highes

Bumek [7]

Answer:

(A) 139°

Step-by-step explanation:

What we are trying to find here is the distance between -27 and 112.

To do this, we have to think of it as a number line.

The distance from -27 to 0 is 27 units, and the distance from 0 to 112 is 112 units.

So the total distance is $112+27=139$

Hope this helped!
