5÷x-4 - 2÷x+2 = 4÷x-4

Alborosie

I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.

LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is

x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10

Subst. 10 for x in the original equation to verify that 10 is indeed a solution.

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

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

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

Rachel withdraws $18 from the bank account once each day for six days. What integer represents the change in the amount in the

Margarita [4]

Answer:

-108

108

Step-by-step explanation:

Since it is withdrawing, we are taking away -$18 every day for 6 days.

(-18)*6 = -108

Since it is deposits, we are adding to the amount in her account, +$18 for 6 days.

18*6 = 108

The difference is that one is taking away and one is adding each day, resulting in negative or positive change.

The questions are illustrations of probability and the usage of two-way tables

<h3>The survey of 1000 Argyle student</h3>

To do this, we make use of the following representations:

x represent owning a cell phone (x' is its complement).
y represent owning a PS5 (y' is its complement).

So, the given parameters are:

Total = 1000

x = 781

x and y = 133

x' and y' = 192

Using the above data values, we have:

y = Total - x

x and y' = x - x and y

x' and y = y - x' and y'

This gives

y = 1000 - 781 = 219

x and y' = 781 - 133 = 648

x' and y = 219 - 192 = 27

See attachment for the complete table.

<h3>The probability of cats</h3>

<u>Probability that cats prefer flying</u>

This is calculated as:

P = Flying/Total

So, we have:

P = 20/100 = 1/5

<u>Probability that a selected cat is an alley cat</u>

This is calculated as:

P = Alley Cat/Total

So, we have:

P = 41/100

<u>Probability that a selected alley cat prefers invisibility</u>

This is calculated as:

P = Alley Cat and Invisible/Alley Cat

So, we have:

P = 21/41

<u>Probability that a selected home cat prefers invisibility</u>

This is calculated as:

P = Home Cat and Invisible/Home Cat

So, we have:

P = 22/59

<h3>Ice cream flavors</h3>

<u>Probability of Peanut Butter Crunch</u>

The given parameters are:

Peanut Butter Crunch = 1

Flavors = 52

This probability is then calculated as:

P = Peanut Butter Crunch/Total

So, we have:

P = 1/52

<u>Theoretical probability of Cotton Candy</u>

In this case, we have:

Cotton Candy = 1

Flavors = 5

This probability is then calculated as:

P = Cotton Candy/Flavors

So, we have:

P = 1/5

<u>Experimental probability of Mango</u>

In this case, we use the table results i.e.

Mango = 1

Friends = 15

This probability is then calculated as:

P = Mango/Friends

So, we have:

P = 1/15

Hence, the experimental probability of Mango is 1/15
