Jerry and Katja are running in a race. Jerry runs really fast for a while. Then, he stops to catch his breath. After he has rest

dimaraw [331]

Katja would be the straight line and joels line would show sections that stop going up it would intersect at some point because katja is constantly moving while joel takes breaks in-between

Hope this helps!! :))

If K = (AB)/(A+B) , then B = ?

marysya [2.9K]

Lets do

$\\ \sf\longmapsto K=\dfrac{AB}{A+B}$

$\\ \sf\longmapsto \dfrac{1}{K}=\dfrac{A+B}{AB}$

$\\ \sf\longmapsto \dfrac{1}{K}=\dfrac{1}{A}+\dfrac{1}{B}$

$\\ \sf\longmapsto \dfrac{1}{B}=\dfrac{1}{K}-\dfrac{1}{A}$

$\\ \sf\longmapsto \dfrac{1}{B}=\dfrac{K-A}{AK}$

$\\ \sf\longmapsto B=\dfrac{AK}{K-A}$

21 POINTS!! Thank you so much!! There’s also things on my page worth lots points points as well! So if you could help with those

Art [367]

Answer:

Second one

third one

fifth one

last one

Step-by-step explanation:

Based on the x intercepts we can write

a(x+1)(x-5)

where a is some constant

solve for a by plugging in some coordinates

let's plug in (1,-8)

-8=a(1+1)(1-5)

-8= -8a

a=1

therefore the quadratic is (x+1)(x-5)

expand this

x²-4x-5

To find out where something is decreasing/increasing it's easiest to take the first derivative

x²-4x-5= 2x-4

set this equal to 0

2x-4=0

2x=4

x=2

Which means that our two intervals are

(-∞,2)U(2,∞)

plug in any values in the intervals to see whether or not the function is increasing/decreation

Let's plug in 0 for (-∞,2)

2(0)-4

-4

It's negative so it's decreasing on this interval

DO the same thing with the other one

let's plug in x=3

2(3)-4

this is positive so it's increasing on this interval

Go back to the critical value of x=2 and plug this into the equation to find the max/min

(2+1)(x-5)= -9

This is a minimum because the cofeccient for the degree is positive

For the limit one notice that we have a positive, even degree which means the end behavior is positive, positive

what this means is as x approaches negative infinity it's infinity

and as x approaches infinity it's infinity

Answer: $\bold{\dfrac{1}{4,}\qquad \dfrac{1}{2,}\qquad \dfrac{1}{8}}$

Step-by-step explanation:

Probability of an A out of A, B, C, D is: $\dfrac{1}{4}$

Probability of an odd (1, 3, 5) out of 1, 2, 3, 4, 5, 6 is: $\dfrac{3}{6}=\dfrac{1}{2}$

Probability of an A and an odd is: $\dfrac{1}{4}\times\dfrac{1}{2}=\dfrac{1}{8}$

*******************************************************************************

Answer: $\bold{\dfrac{1}{2}}$

Step-by-step explanation:

Probability of an odd (1, 3, 5) out of 1, 2, 3, 4, 5, 6 is: $\dfrac{3}{6}=\dfrac{1}{2}$

*******************************************************************************

Answer: $\bold{\dfrac{3}{4}}$

Step-by-step explanation:

Probability of an A or an odd is: $\dfrac{1}{4}+\dfrac{1}{2}=\dfrac{1}{4}+\dfrac{2}{4}=\dfrac{3}{4}$
