In Exercise, find the derivative of the function. <br> y = 32e0.23t

TEA [102]

Answer:

$y'=7.36e^{0.23t}$

Step-by-step explanation:

$y=32e^{0.23t}$

take derivative with respect to t

$\frac{dy}{dt} =32\frac{d(e^{0.23t})}{dt}$

derivative of e^t is e^t

derivative of 0.23t is 0.23

$\frac{dy}{dt} =32 \frac{d(e^{0.23t})}{dt}$

Apply chain rule

$\frac{dy}{dt} =32(e^{0.23t})(0.23)$

$y'=7.36e^{0.23t}$

What is the length of the mid segment of this trapezoid ; a(-2,4) b(4,3) c(4,-5) d(-2,-2)

Elina [12.6K]

Answer:

$7\ units$

Step-by-step explanation:

we have

a(-2,4), b(4,3), c(4,-5), d(-2,-2)

step 1

Plot the vertices to better understand the problem

using a graphing tool

The graph in the attached figure

step 2

Find the mid-segment parallel to ad and bc

Note : The mid-segment is parallel to the parallel bases of trapezoid

Let

e ---> midpoint segment ab

f ---> midpoint segment cd

The formula to calculate the midpoint between two points is equal to

$(\frac{x1+x2}{2},\frac{y1+y2}{2})$

<em>Find the midpoint e </em>

we have

a(-2,4) and b(4,3)

substitute the given values

$e\ (\frac{-2+4}{2},\frac{4+3}{2})$

$e\ (1,3.5)$

<em>Find the midpoint f </em>

we have

c(4,-5), d(-2,-2)

substitute the given values

$f\ (\frac{4-2}{2},\frac{-5-2}{2})$

$f\ (1,-3.5)$

step 3

Find the length of the mid-segment ef

we have

$e\ (1,3.5)$

$f\ (1,-3.5)$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute

$d_e_f=\sqrt{(-3.5-3.5)^{2}+(1-1)^{2}}$

$d_e_f=\sqrt{(-7)^{2}+(0)^{2}}$

$d_e_f=\sqrt{49}\ units$

$d_e_f=7\ units$

I don’t understand this

bogdanovich [222]

$\frac{20}{20} = \frac{19}{20} + x \\ \frac{20}{20} - \frac{19}{20} = x \\ \frac{1}{20} = x$

A regular hexagon is shown below. Find the value of x.

Cloud [144]

The measure of each interior angle of the hexagon is 120°. Then the value of x will be 20°.

<h3>What is a polygon?</h3>

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

A regular hexagon is shown below.

Then the internal angle of the hexagon is (5x + 20)°.

Then the value of x will be

We know that each interior angle of the hexagon is 120°.

Then we have

5x + 20 = 120

5x = 100

x = 20
