the graph of y=e^tanx-2 crosses the x axis at one point in the interval [0,1]. What is the slope of the graph at this point? I g
Svetlanka [38]
Y = e^tanx   -   2

To find at which point it crosses x axis we state that y= 0

e^tanx   - 2 = 0 
e^tanx = 2
tanx = ln 2
tanx = 0.69314
x = 0.6061

to find slope at that point first we need to find first derivative of funtion y.

y' = (e^tanx)*1/cos^2(x)

now we express x = 0.6061 in y' and we get:
y' = k = 2,9599

HELP ME!!! 25 POINTS!!
riadik2000 [5.3K]

Answer:

The total distance walked by Paulo is 3750 feet.

Step-by-step explanation:

Here the four points are<em> (-2,1) (-2,-7) (5,-7) (5,1)</em>

Moving from stop A to B, only the y coordinate changes,

the change is ,

=1-(-7) = 1+7 = 8 units

Moving from stop B to C, only the x coordinate changes,

the change is ,

=5-(-2) = 5+2 = 7 units

Moving from stop C to D, only the y coordinate changes,

the change is

=1-(-7) = 1+7 = 8 units

Moving from stop D to A, only the x coordinate changes,

the change is

=5-(-2) = 5+2 = 7 units

Thus, the total distance traveled is 8+7+8+7 = 30 units

It is given that <em>1 unit = 125 feet</em>

Thus, the total distance traveled is = (125)(30) = 3750 feet

The total distance walked by Paulo is 3750 feet.

PLEASE HELP ASAP (8)/(27) a^(15) cube of a monomial
vagabundo [1.1K]

Answer:

2/3a^5

Step-by-step explanation:

we know that 2/7x2/7x2/7 = 8/27

a^15  cube will be a^5

because we know (2^3)^2 = 2^6

so (a^5)^3 = a^15

2/3a^5
