Answer:

Step-by-step explanation:

hello :

let   :   y=f(x)

f(x)==x(x-2)^3   so : f'(x) = 1.(x-2)^3+3x(x-2)²

f'(x) = (x-2)²(x-2+3x)

f'(x) = (x-2)²(4x-2)

f'(x) =0    : x=2  or x=1/2

the minumum is (1/2 ,f(2))

the inflection points use f"(x) = 0.......continu

Two roller coasters are vying for the title of the steepest drop the first ride has a hill that drops 140 feet in a 40 foot run
muminat

Answer:

They have the same slope

Step-by-step explanation:

Given

Coaster 1:

Drops = 140ft

Run = 40ft

Coaster 2:

Drops = 105ft

Run = 30ft

First, we calculate the slope (m) of both coasters

m = \frac{Rise}{Run}

m = \frac{Drops}{Run}

For coaster 1:

m = \frac{140ft}{40ft}

m = \frac{140}{40}

m = 3.5

For coaster 1:

m = \frac{105ft}{30ft}

m = \frac{105}{30}

m = 3.5

<em></em>m = m=>3.5 = 3.5<em></em>

<em>By comparison, they have the same slope</em>

Converse (switch p and q)
If an angle is obtuse, then it measures 128°

This is false (a 127° angle is obtuse, but it does not measure 128°)

_____________________________________________________________

Inverse
(negations of p and q)
If an angle does not measure 128°, then it is not obtuse

This is false (a 127° angle does not measure 128°, but it is obtuse)

_____________________________________________________________

Contrapositive (negations of p and q, then switch their places)

If an angle is not obtuse, it does not measure 128°

This is true (any 128° is obtuse; no exceptions)

For the following telescoping series, find a formula for the nth term of the sequence of partial sums
gtnhenbr [62]

I'm guessing the sum is supposed to be

\displaystyle\sum_{k=1}^\infty\frac{10}{(5k-1)(5k+4)}

Split the summand into partial fractions:

\dfrac1{(5k-1)(5k+4)}=\dfrac a{5k-1}+\dfrac b{5k+4}

1=a(5k+4)+b(5k-1)

If k=-\frac45, then

1=b(-4-1)\implies b=-\frac15

If k=\frac15, then

1=a(1+4)\implies a=\frac15

This means

\dfrac{10}{(5k-1)(5k+4)}=\dfrac2{5k-1}-\dfrac2{5k+4}

Consider the nth partial sum of the series:

S_n=2\left(\dfrac14-\dfrac19\right)+2\left(\dfrac19-\dfrac1{14}\right)+2\left(\dfrac1{14}-\dfrac1{19}\right)+\cdots+2\left(\dfrac1{5n-1}-\dfrac1{5n+4}\right)

The sum telescopes so that

S_n=\dfrac2{14}-\dfrac2{5n+4}

and as n\to\infty, the second term vanishes and leaves us with

\displaystyle\sum_{k=1}^\infty\frac{10}{(5k-1)(5k+4)}=\lim_{n\to\infty}S_n=\frac17

Point Mis the midpoint of AB. AM = 3x + 3, and AB= 83 – 6.
Ber [7]

Answer:

AM= Half of AB

or, 3x+3=(8x-6)/2

or, 6x+6=8x-6

or, 2x=12

Therefore,x=6

so,AM=3*6+3=21

So the units is 21
