Answer:352 square inches

Step-by-step explanation:edge

Answer:

25% chance

Step-by-step explanation:

Yes, it would be a scalene triangle. This can happen.

The Triangle sides have to be greater than c.

a+b > c

With the given inches, substitute it into the equations:

a = 3 in

b = 5 in

c = 9 in

3 + 5 > 9

Solve.

9 > 9

This is False since because a + b is not > c. a + b is equal to c.

Given:

Amount saved in sale = $25

Sale price was 35% off the regular price.

To find:

The regular price of the tennis shoes.

Solution:

Let the regular price of the tennis shoes be x.

Sale price was 35% off the regular price.

\(Discount=\dfrac{35}{100}x\)

Amount saved in sale = $25

\(0.35x=25\)

Divide both sides by 0.35.

\(x=\dfrac{25}{0.35}\)

\(x=71.42857\)

\(x\approx 71.43\)

Therefore, the regular price of the tennis shoes is $71.43.

The probability of selecting an orange marble is 0.33.

Option B is the correct answer.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

The number of times each marble is selected.

Green = 4

Black = 6

Orange = 5

Total number of times all marbles are selected.

= 4 + 6 + 5

= 15

Now,

The equations for the lines tangent to the function f(x) = x³ - x² - 2x + 2 at the points where the slope of the tangent line is 1/2 in point-slope form are y = 1/2 x + 2/27 and y = 1/2 x + 17/54.

To find the equation of the tangent lines to a function at a given point, we need to find the derivative of the function and evaluate it at that point.

Let's find the derivative of the function: f(x) = x^3 - x^2 - 2x + 2:

\($$f(x) = x^3 - x^2 - 2x + 2$$\)

Differentiating with respect to x, we get:

\($$3x^2 - 2x - 2 = \frac{1}{2}$$$$6x^2 - 4x - 5 = 0$$\)

Now we need to find the value of x where the slope of the tangent line is 1/2.

Solving for x gives:

\($$3x^2 - 2x - 2 = \frac{1}{2}$$$$6x^2 - 4x - 5 = 0$$\)

This is a quadratic equation that can be solved using the quadratic formula:

\($$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$$$x = \frac{2 \pm \sqrt{4 + 120}}{12}$$$$x = \frac{1}{3}, -\frac{5}{6}$$\)

So we have two points where the slope of the tangent line is 1/2: (1/3, f(1/3)) and (-5/6, f(-5/6)).

We can use point-slope form to write the equations of the tangent lines:

At (1/3, f(1/3)):

\($$y - f(1/3) = \frac{1}{2}(x - 1/3)$$$$y - (\frac{16}{27}) = \frac{1}{2}(x - \frac{1}{3})$$or$$y = \frac{1}{2}x + \frac{2}{27}$$\)

At (-5/6, f(-5/6)):

\($$y - f(-5/6) = \frac{1}{2}(x + \frac{5}{6})$$$$y - (\frac{1}{27}) = \frac{1}{2}(x + \frac{5}{6})$$or$$y = \frac{1}{2}x + \frac{17}{54}$$\)

Hence, the equations for the lines tangent to the function f(x) = x³ - x² - 2x + 2 at the points where the slope of the tangent line is `1/2` in point-slope form are y = 1/2 x + 2/27 and y = 1/2 x + 17/54.

Answer: i dont really understand the question but x = 6 if that's what your asking :)

Step-by-step explanation:

The y intercepts of the quadratic equation y = x² - 5x + 6 is given by (0 , 6)

and the x intercepts are ( 3 , 0 ) and ( 2, 0 )

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

y = x² - 5x + 6   be equation (1)

On simplifying the equation , we get

y = x² - 2x - 3x + 6

Taking the common factors of the equation , we get

y = x ( x - 2 ) - 3 ( x - 2 )

On factorizing the equation , we get

y = ( x - 3 ) ( x - 2 )

To find the y intercepts , substitute the value of x = 0 , we get

y = ( 0 - 3 ) ( 0 - 2 )

y = ( -3 ) ( -2 )

So , y = 6

Hence , the y intercepts of the equation is  ( 0 , 6 )

According to the question, there are 38,760,720 possible samples in the sample space when selecting 5 objects from a set of 56 objects.

To determine the total number of samples in the sample space, we need to calculate the number of possible arrangements or permutations of selecting 5 objects from a set of 56 objects.

The formula to calculate permutations is given by:

\(\[ P(n, r) = \frac{n!}{(n-r)!} \]\)

Where n represents the total number of objects and r represents the number of objects being selected.

In this case, we have 56 objects and we want to select 5 objects. Using the permutation formula, we can calculate the total number of samples:

\(\[ P(56, 5) = \frac{56!}{(56-5)!} \]\)

Simplifying the expression:

\(\[ P(56, 5) = \frac{56!}{51!} \]\)

Calculating the factorials:

\(\[ P(56, 5) = \frac{56 \times 55 \times 54 \times 53 \times 52}{1} \]\)

Thus, the total number of samples in the sample space is:

\(\[ P(56, 5) = 38,760,720 \]\)

Therefore, there are 38,760,720 possible samples in the sample space when selecting 5 objects from a set of 56 objects.

When 100 ft of rope is out, the boat will be approaching the dock at a rate of approximately 13.02 ft/min.

To solve this problem, we can use related rates and the concept of similar triangles.

Let's denote the rate at which the boat is approaching the dock as dB/dt (the rate of change of the distance between the boat and the dock).

Given that the rope is being pulled at a rate of 14 ft/min (dr/dt = 14 ft/min), we want to find dB/dt when 100 ft of rope is out.

We can set up a proportion between the lengths of the rope and the distances between the boat and the dock:

Length of rope / Length of distance = Length of rope being pulled / Rate of change of distance

100 ft / (distance - 7 ft) = 14 ft/min / dB/dt

We want to find dB/dt, so let's solve for it:

dB/dt = (14 ft/min * (distance - 7 ft)) / 100 ft

Now, let's substitute the given value for the length of the rope:

dB/dt = (14 ft/min * (100 ft - 7 ft)) / 100 ft

= (14 ft/min * 93 ft) / 100 ft

= 13.02 ft/min

Therefore, when 100 ft of rope is out, the boat will be approaching the dock at a rate of approximately 13.02 ft/min.

Three lollipops are more expensive than two pencils.

Given that three erasers cost as much as 2 lollipops.

Let e denote the cost of an eraser and l denote the cost of a lollipop.

A pencil costs as much as two erasers, which implies that the cost of a pencil is two times the cost of an eraser. Therefore, the cost of a pencil is 2e.

Likewise, three erasers cost as much as 2 lollipops, which implies that the cost of an eraser is (2/3) l.

Therefore, the cost of a pencil is 4/3 times the cost of a lollipop.

Thus, the cost of two pencils is 4/3 * 2l = 8/3 l.

The cost of three lollipops is 3l.

Now, we must determine whether 8/3 l is greater than 3l or vice versa.

8/3 l = 2.67 l

Since 2.67 l < 3 l, the conclusion is that three lollipops are more expensive than two pencils.

What is a fraction?

Any numerical number which does not represent the entire quantity is called a fraction. It depicts a part or portion of something. It is generally written in the form of numerator by denominator.

Calculation of the total time Yolanda spends playing soccer

Given that Yolanda plays soccer for 8 ⅔ hours in a month

Firstly, convert the hours in mixed fraction to improper fraction i.e. 8 ⅔ = (8 × 3 + 2) / 3

= 26 / 3

Now, we need to calculate the no. of hours she played in a year, which is done by multiplying the obtained improper fraction with 12

(a) When particles with diameters > 50 μm are inhaled, they are more likely to be deposited in the upper airways by inertial impaction.

(b) Decreasing the oxygen level to below the MOC is not a valid approach for explosion hazard control.

(c) Particles with a density of 1200 kg.m-³ and an average diameter of 10 µm are expected to show fluidization with immediate bubble formation.

(d) To decrease pumping costs for a slurry with high viscosity, the addition of low molecular weight adsorbing polymers would be recommended.

When particles with diameters > 50 μm are inhaled, they are more likely to be deposited in the upper airways by inertial impaction. Inertial impaction occurs when particles with sufficient mass and momentum are unable to follow the airstream and impact the walls of the airways.

Decreasing the oxygen level to below the Minimum Oxygen Concentration (MOC) is not a valid approach for explosion hazard control. The MOC represents the minimum oxygen concentration required for combustion to occur. Depleting oxygen below this level can prevent combustion and reduce the risk of explosions.

Particles with a density of 1200 kg.m-³ and an average diameter of 10 µm are expected to show fluidization with immediate bubble formation. These particles are relatively dense and larger in size, leading to rapid fluidization and the formation of bubbles within the fluidized bed.

To decrease pumping costs for a slurry with high viscosity, the addition of low molecular weight adsorbing polymers would be recommended. These polymers can act as flow aids, reducing the viscosity of the slurry and improving its pump ability. The polymers adsorb onto the surface of the particles, reducing interparticle interactions and increasing fluidity. This helps in reducing the energy required for pumping the slurry through the pipeline.

In summary, particles > 50 μm settle in the upper airways, and decreasing oxygen below the MOC is not a valid explosion hazard control strategy,  particles with a density of 1200 kg.m-³ and an average diameter of 10 µm show fluidization with immediate bubble formation, and the addition of low molecular weight adsorbing polymers is recommended to decrease pumping costs for a high-viscosity slurry.

The Marginal Rate of Substitution (MRS) for the given function is equal to -2/sqrt(x). To find the Marginal Rate of Substitution (MRS), we need to take the derivative of the given function with respect to x.

Given: y = 24 - 4(sqrt(x))

Step 1: Differentiate the function y with respect to x.

dy/dx = d/dx(24 - 4(sqrt(x)))

Step 2: Differentiate each term separately using the power rule and chain rule.

dy/dx = 0 - 4(1/2)(x^(-1/2))(1)

Step 3: Simplify the derivative.

dy/dx = -2(x^(-1/2))

Step 4: Rewrite the derivative in terms of MRS.

MRS = dy/dx = -2/sqrt(x)

Therefore, the Marginal Rate of Substitution (MRS) for the given function y = 24 - 4(sqrt(x)) is -2/sqrt(x).

The negative sign indicates that the MRS is inversely related to x, which means as x increases, the MRS decreases. The value of MRS represents the rate at which a consumer is willing to substitute y (the dependent variable) for an incremental change in x (the independent variable). In this case, as x increases, the consumer is willing to substitute less y for the additional units of x.
