\(\frac{AB}{A"B"} = \frac{1}{4}\)  equation clearly illustrates how AABO and AA"B"C relate to one another.

An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

The three main types of linear equations are the slope-intercept form, standard form, and point-slope form.

Considering the data:

Dilation by a scale factor of 4 from the origin in the form of an A'B'C' reflection over x = 1

<=> The two triangles are comparable to one another since triangles can have the same shape but differ in size, so A′′B′′C′′ is 4 times larger than ABC.

=> the connection between "ABC" and "A"B"C" .

\(\frac{AB}{A"B"} = \frac{1}{4}\)

We settle on C.

Step-by-step explanation:

step 1: how many dolphins

there are 6 sharks

sharks to dolphins is 3 to 5

3 S to 5 D

we can divide 6 (amount of sharks known) by 3, to get what a ratio of 1 is

6 ÷ 3 = 2

so 2 sharks is = 1 part or ratio

now we can times by 5 to get a ratio of 5

5 × 2 = 10

there are 10 Dolphins

Step 2: How many starfish

repeat the steps above but for the ratio 2: 7 where 2 is the Dolfin ratio and there are 10 dolphins

put in questions answer you got

Answer:

35 starfish

Step-by-step explanation:

shark/dolphin  *  dolphin /starfish = shark / starfish

Now. put in the numbers given:

3/5 * 2/7 =      6/35  = shark / starfish    put in '6' for shark (given)

        6/35 = 6/starfish        cross multiply

        6 * starfish = 35* 6

Answer:

9:45 AM

Step-by-step explanation:

To get to work in the morning, Amanda cycles for 10 miles at the rate of 12 mph.

Time (hours) = Distance/speed

Hence, the time she spends cycling = 10mile/12 mph

= 0.8333333333 hour

Converting to minutes:

1 hour = 60 minutes

0.8333333333 hour =

0.8333333333 hours × 60 minutes/1 hour

= 50 minutes.

Hence, she spends 50 minutes cycling

She makes a 10 minutes stop for a cup of coffee, and then rides a bus for 15 minutes. The speed of the bus is 45 mph.

The total number of minutes she spends to get to work is calculated as:

(50 + 10 + 15)minutes

= 75 minutes.

It takes Amanda 75 minutes to get to work.

At what time will Amanda get to work if she leaves home at 8:30 AM?

= 8:30AM + 75 minutes

= 8:30 AM + 1 hour 15 minutes

= 9:45 AM

The partial fractions technique is not applicable because the degree of the numerator (x^3) is not less than the degree of the denominator (x^4 + 73x^2 + 576). For the partial fractions technique to be applicable, the degree of the numerator should be less than the degree of the denominator.

Using the partial fractions technique, the function f(x) = x3 can be written as a sum of partial fractions X4+73x2+576 as shown in equation f(x) = X3 / (X4+73x2+576). The integral of the function f(x) can then be found by using the formula for integrating fractions. The result is:

|F(x) dx = 1/4 (ln|X2+24x| - 3/2 arctan(3x/8) + C)

where C is the constant of integration.
Using the partial fractions technique, the function f(x) = x^3 / (x^4 + 73x^2 + 576) can be written as a sum of partial fractions. To find the integral of the function, we need to first decompose the function into simpler fractions, then integrate each of the simpler fractions.

Answer:

x = 10

\( m\angle DCE=55\degree \)

Step-by-step explanation:

Since, CE bisects angle DCF, therefore:

\( m\angle ECF= m\angle DCE\)

\( 6x-5=4x + 15 \)

\( 6x-4x=5 + 15 \)

\( 2x=20 \)

\( x=\frac{20}{2} \)

\( x=10\)

\( m\angle DCE=(4x+15)\degree \)

\( m\angle DCE=(4\times 10+15)\degree \)

\( m\angle DCE=(40+15)\degree \)

\( m\angle DCE=55\degree \)

B. They decrease, approaching zero

Step-by-step explanation:

just got it right !

As the positive [x] values reaches zero, the [y] values reach zero.

The domain and range of the function f(x) = x⁻² is

Domain → (−∞,∞) , {x | x ∈ R}

Range → [0,∞) , {y | y ≥ 0}

We have the following function -

f(x) = 10/x²

Given is the function -

f(x) = 10/x²

Refer to the graph attached. As the positive [x] values reaches zero, the [y] values reach zero.

Therefore, as the positive [x] values reaches zero, the [y] values reach zero.

It takes approximately 3 hours for an average adult to metabolize four 12-ounce beers.

The alcohol has a half-life of about 3 hours. This means that for every three hours that pass, the amount of alcohol in your body decreases by half. Alcohol is metabolized primarily in the liver.

Here, enzymes break down the ethanol molecule and turn it into a less toxic chemical called Acetaldehyde. Acetaldehyde is then further broken down by the enzyme aldehyde dehydrogenase into Acetic acid. Acetic acid is then further broken down into water and Carbon dioxide and eventually eliminated from the body.

So, for an average adult, it takes approximately 3 hours to metabolize four 12-ounce beers. The rate of metabolism can be affected by a number of factors such as age, gender, body composition, and the rate at which the alcohol was consumed.

Additionally, factors such as weight, body fat percentage, and the amount of food in the stomach can also influence the rate of alcohol metabolism. It is important to note that even after the alcohol is metabolized, it can still remain in the system and affect cognitive and motor skills.

Therefore, it is important to give the body enough time to metabolize the alcohol before attempting to drive or operate any type of machinery.
