Matthew picks flowers and sells them to tourists. the function s(t) approximates how many flowers matthew picks per hour. the function w(h) represents how hours per week matthew spends picking flowers. what are the units of measurement for the composite function s(w(h))?

Answer:

Option A) [tex]\bf{ x^{\frac{2}{7}}*y^{-\frac{3}{5}}}[/tex]

Step-by-step explanation:

we have

[tex]\sf{\dfrac{\sqrt[7]{x^{2}}}{\sqrt[5]{y^{3}}}}[/tex]

we know that

[tex]\sf{\sqrt[7]{x^{2}}=x^{\frac{2}{7}}}[/tex]

[tex]\sf{\sqrt[5]{y^{3}}=y^{\frac{3}{5}}}[/tex]

substitute in the expression

[tex]\sf{\dfrac{x^{\frac{2}{7}}}{y^{\frac{3}{5}}}=x^{\frac{2}{7}}*y^{-\frac{3}{5}}}[/tex]

The constant of proportionality between the number of bolts and the number of hours is 2025.

Option B is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Using a ∝ b then a = kb

Where k is the proportionality constant.

Given that;

We substitute into our equation.

a = kb

16200 = k × 8

k = 16200 / 8

k = 2025

The constant of proportionality between the number of bolts and the number of hours is 2025.

Option B is the correct answer.

Step-by-step explanation:

An adult with a weight of 75 kilograms have an equivalent weight of 165.60 pounds.

Herein we have an application of unit conversions between weight units, from kilograms to pounds. Unit conversions follow this direct proportional formula:

y = k · x

Where:

x - Weight in kilograms

y - Weight in pounds

k - Conversion ratio

If we know that x = 75 kg and k = 2.208 lb/kg, then the weight of the adult in pounds is:

The domain of A(r) will be (0, ∞), the inverse function to A(r) will be r = 2π[A(r)]² + 12πA(r), and the radius will be 3.07 inches.

A statement, principle, or policy that creates the link between two variables is known as a function.

A cylinder (round can) has a circular base and a circular top with vertical sides in between.

Let r be the radius of the top of the can and let h be the height.

The surface area of the cylinder (A) is given as

A=2πr² + 2πrh

Part A: Assume that the height of your cylinder is 6 inches.

Consider A as a function of r, so we can write that as

A(r) = 2πr² + 12πr

Then the domain of A(r) will be (0, ∞).

Part B: Continue to assume that the height of your cylinder is 6 inches.

Then the inverse function to A(r) will be

r = 2π[A(r)]² + 12πA(r)

Part C: If the surface area is 175 square inches.

Then the radius will be

                    175 = 2πr² + 12πr

r² + 6r – 27.866 = 0

Answer: First step is to determine the total cost

Total cost at 2,800

=$0.80 ×2,800

=$2,240

Total cost at 5,600

=$0.75 × 5,600

=$4,200

Second step is to determine the Variable cost per unit

Variable cost per unit=$4,200-$2,240

Variable cost per unit=$1,960

Variable cost per unit=5,600-2,800

Variable cost per unit=2,800

Variable cost per unit=$1,960/2,800

Variable cost per unit=$0.70

Now let determine the average cost

Average cost=$0.70×4,800+[($0.80×2800)-(2,800 ×$0.70)]

Average cost=$3,360+($2,240-$1,960)

Answer:

The first one: 12/13  > 36/30

Step-by-step explanation:

The first one would be correct as 12/13 is less than 36/30.

To explain why 13/17 is actually less than 24/28, see below:

So when comparing fractions, we must follow steps.

Step One: convert mixed numbers to a fraction, if there are any

There are not mixed numbers to compare, so we can move to the next step.

Step Two: find the least common denominator of the two fractions

Least common denominator = 476

Check out our least common denominator calculator for help on finding this.

Step Three: rewrite each fraction to an equivalent fraction using the denominator 476

To do this, start by dividing 476 by the denominator of the first fraction. Next, multiply the result by the numerator to find the new numerator. To rewrite, put the new numerator over 476. Repeat this for the second fraction

364/476                              408/476

Step Four: compare the numerators

At this point, to compare the fractions, we can simply compare the numerators to see which is larger

364<408

Step Five: rewrite each fraction as the original fraction

13/17<24/28

Therefore, the first statement (12/13 > 36/30) is true.

Answer:

  12/13 < 36/30

Step-by-step explanation:

There are many ways to compare numbers. One way is to compare them to some value that lies between. Another is to consider their difference from a value that does not lie between.

In the first fraction, 12 < 13, so the value of the fraction is less than 1:

  12/13 < 1

In the second fraction, 36 > 30, so the value of the fraction is greater than 1:

  1 < 36/30

Then the order of the fractions is ...

  12/13 < 1 < 36/30

  12/13 < 36/30 . . . . . the given order is True

We notice the difference between numerator and denominator is 4 in each case, so we can write each fraction as a difference from 1:

  (13/17) vs (24/28)

  = (1 - 4/17) vs (1 -4/28) . . . . . fractions rewritten

  = -4/17 vs -4/28 . . . . . . . . . subtract 1 from both

The first fraction, 4/17, has a smaller-value denominator, so its magnitude is larger than that of the fraction 4/28. In other words, the ordering of these fractions is ...

  -4/17 < -4/28

  1 -4/17 < 1 -4/28 . . . . . . add 1 to both sides

  13/17 < 24/28 . . . . . the given order is False

__

Additional comment

One sort of "no brainer" way to compare the fractions is to multiply them by the product of their denominators. This looks like "cross multiplication" where each numerator is multiplied by the opposite denominator. As long as you keep the numerators in the same relative places, the comparison symbol will be the correct one for the fractions.

  12/13 vs 36/30   ⇒   (12·30) vs (13·36)   ⇒   360 < 468

The left fraction is smaller than the right fraction.

Similarly, ...

  13/17 vs 24/28   ⇒   (13·28) vs (17·24)   ⇒   364 < 408

The left fraction is smaller than the right fraction.

__

Here, we have used the fractions "as is." In each case, the fraction on the right could be reduced, possibly making the comparison easier.

The object compresses the spring up to 0.8577m.

Potential Energy is the energy possessed by an object at rest.

The object is falling from the rest and it is assumed that the friction on the ramp is zero and the air resistance is also considered to be zero so only the gravitational force acts and the total potential energy gets converted to Kinetic Energy.

The total amount of potential energy at the top of the ramp is given by

Ep=mgh

Ep=3 * 9.81 *5

Ep=147.15 Joules

This is equal to kinetic energy.

From the formula for elastic potential energy

The distance up to which the spring is compressed is determined

The force constant = 400N/m

147.15 =(1/2)k(x²)
