Answer:

V =144 pi units^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

where r is the radius and h is the height

V = pi (6)^2 *4

V = pi 36*4

V =144 pi units^3

Answer:

V=452.16 units^2

Step-by-step explanation:

The formula to find the volume of a cylinder is ...

V=(3.14)r^2×h

(3.14)=pie

r^2=radius squared

h=height

So....

Let's plug in what we know

V=(3.14)6^2×4

V=(3.14)36×4

V=(3.14)144

V=452.16 units

300,000 cm³

EXPLANATION

We want to round

[tex]257, 166 {cm}^{3} [/tex]

to the nearest hundred thousand.

The digit in the hundred thousand position is '2'

The immediate digit to it's right is 5.

So we round up to obtain

300,000 cm³

Therefore, 257,166 cm³ rounded to the nearest hundred thousand is 300,000 cm³

The number present at hundred thousand places is 2 can be turned to 3 and rest all will zero to obtain 257, 166 rounded to the nearest hundred thousand. Thus, the nearest hundred thousand of 257,166 is 3,00,000.

The number is 2,57,166 that is needs to be rounded to the nearest hundred thousand.

In the image, each and every position is mentioned clearly.

Therefore,

The number present at hundred thousand places is 2.

The next number present to the left from 2 is 5 that is neutral, so, we need to check the number left to the 5 that is 7.

Now,

7 is a large number so we can consider 5 as a large number.

Thus,

The number present at hundred thousand places is 2 can be turned to 3 and rest all will zero to obtain 257, 166 rounded to the nearest hundred thousand. Thus, the nearest hundred thousand of 257,166 is 3,00,000.

Final answer:

Chantale's motion can be graphically represented on a position-time graph, with walking segments shown by lines with positive slopes, the running back segment by a line with a negative slope, and the stationary segment at school by a horizontal line.

Explanation:

The question pertains to plotting a graph of Chantale's motion as she moves to and from school, which is a concept from kinematics in physics. We can visualize her walk as a position-time graph, where each part of her travel (A to D) corresponds to a different segment of the graph.

A. Walking towards home: This would be represented by a line moving away from the origin (assuming the school is the origin) with a positive slope, showing that distance from school is increasing over time.

B. Running back to school: This segment of the graph will have a negative slope as Chantale moves closer to the origin (school).

C. Spending 2 minutes at school: During this time, her position does not change, so the graph will show a flat, horizontal line indicating no movement.

D. Walking back home: This would again be a line with a positive slope as she moves away from the school to her house.

To encompass the entire journey, you would see a graph with segments that reflect these motions, and each segment would follow the order of actions A to D.

Answer:

34n

Step-by-step explanation:

The product of 34 and the number of pounds

The product means multiply

So the product of 34 and the number of pounds = 34 × n = 34n

The question involves mathematical conversion of units from pounds to ounces and calculating percent composition. Multiplying by 16 converts pounds to ounces, while percent composition is found by dividing the mass of the component by the total mass and then multiplying by 100. Exact numbers, like the number of bags, do not affect significant figures.

The student appears to be dealing with a conversion problem within a mathematics context, specifically involving the units of pounds and ounces. When converting from a larger unit (pounds) to a smaller unit (ounces), the correct operation is multiplication since there are 16 ounces in one pound. A clear example of this is provided where 4.5 pounds, written as 4(1/2) pounds, is converted to ounces resulting in 72 ounces.

Furthermore, the problem addresses the percent composition of a substance by mass, which is a concept commonly encountered in chemistry but framed here within a mathematical question. Using the provided formula and mass values, we calculate the percent composition by dividing the mass of the desired product by the total mass of the product and then multiplying by 100 to get a percentage. The percentages indicate the fraction of the total mass that is made up of a specific component. The key information given in the example is that the mass of the desired product is 73.0, and the total mass of the product is 215, therefore, the percent composition is 34.0%.

Lastly, the question states that because the number of bags is an exact value, it is not considered in the significant figures. This means we are not to worry about the precision of measurement when it comes to counting items, which is a principle applied to exact numbers in significant figure rules.

Answer:

x = 3 and y = 3

Step-by-step explanation:

2 x + 3 y = 15 { Equation 1 }

x + y = 6 { Equation 2 }

( Multiply the x variable by 2 so equation 1 and 2 have the same x variable )

2 x + 3 y = 15 { Equation 1 }

2 x + 2 y = 12 { Equation 2 }

( Minus equation 2 from 1 so we are left with an independent variable )

y = 3

( Substitute y = 3 into equation 1 to solve for x )

2 x + 9 = 15

Step-by-step explanation:

First express [tex]\sqrt{2}[/tex] + i[tex]\sqrt{2}[/tex] in trig form

| z | = [tex]\sqrt{(\sqrt{2})^2+(\sqrt{2})^2  }[/tex] = [tex]\sqrt{4}[/tex] = 2

Θ = [tex]tan^{-1}[/tex]( [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex]) = [tex]tan^{-1}[/tex]( 1) = [tex]\frac{\pi }{4}[/tex]

Thus

[tex]\sqrt{2}[/tex] + i[tex]\sqrt{2}[/tex] = 2 [ cos[tex]\frac{\pi }{4}[/tex] + isin[tex]\frac{\pi }{4}[/tex] ]

Hence

([tex]\sqrt{2}[/tex] + i[tex]\sqrt{2}[/tex] )³

= 2³ [ cos ([tex]\frac{\pi }{4}[/tex] × 3) + isin([tex]\frac{\pi }{4}[/tex] × 3 ) ]

= 8 [ cos([tex]\frac{3\pi }{4}[/tex] ) + isin([tex]\frac{3\pi }{4}[/tex]) ] → A

The standard form of the give complex number is

8 [ cos(\frac{3\pi }{4} ) + isin(\frac{3\pi }{4}) ]

We have given that,

First express  [tex]\sqrt{2} + i\sqrt{2}[/tex]  in trig form

[tex]| z | = \sqrt{(\sqrt{2})^2+(\sqrt{2})^2 } = \sqrt{4} = 2[/tex]

[tex]\theta = tan^{-1}( \frac{\sqrt{2} }{\sqrt{2} }) = tan^{-1}( 1) = \frac{\pi }{4}[/tex]

Thus, [tex]\sqrt{2} + i\sqrt{2} = 2 [ cos\frac{\pi }{4} + isin\frac{\pi }{4} ][/tex]

[ r(cos θ + i sin θ) ]^n = r^n(cos nθ + i sin nθ)

Hence, [tex](\sqrt{2} + i\sqrt{2} )^3[/tex]

[tex]= 2^3 [ cos (\frac{\pi }{4} \times 3) + isin(\frac{\pi }{4} \times 3 ) ][/tex]

[tex]= 8 [ cos(\frac{3\pi }{4} ) + isin(\frac{3\pi }{4}) ] \implies A[/tex]

Thererefore the standard form of the give complex number is

8 [ cos(\frac{3\pi }{4} ) + isin(\frac{3\pi }{4}) ].

Step-by-step explanation:

(x² + x + 2)(x² – 2x + 3)

1. Degree of product

The degree of the product of two polynomials is the sum of their degrees.

Each polynomial is of degree 2, so the degree of the product is 4.

That is, the term of highest degree must come from x² × x² = x⁴.

2. Maximum number of terms

The maximum number of terms is one more than the degree of the product.

Thus, there is a maximum of five terms in the product: one for each power of x plus a constant term.

P = a₁x⁴ + a₂x³ + a₃x² + a₄x + a₅

Answer:

The cost is less than $1.30

Step-by-step explanation:

Let

y-----> the total cost of a mobile phone call

x----> the time in minutes

we know that

if time were x=5 minutes

the cost would be

y=0.30+0.20(5)=$1.30

but

the time is less than 5 minutes

therefore

the cost would be

y< $1.30

Answer:

The possible cost of a call if it is shorter than 5 minutes ranges between 30 cents and maximum 130 cents

Step-by-step explanation:

Define a function as

Y: Cost of a call in cents

X: Number of minutes of call

So using the statement we can find that

Y=30+20X

because the cost of the call has a fix cost of 30 cents plus 20 cents per minute used. If the calls is shorter than 5 minutes for x = 5

Y=30+20X = 30 + (20*5) = 30 + 100 = 130 which is the cost of a call of max 5 minutes

Because you pay a fixed cost of 30 even if you spend very little time. X= 0 then the possible cost of a call if it is shorter than 5 minutes ranges between 30 cents and maximum 130 cents

Answer:

Step-by-step explanation:

xy = 300

x + y = 50                       Solve for y

y = 50 - x                        substitute into xy = 300

x(50 - x) = 300               Remove the brackets.

50x - x^2 = 300             Bring the left to the right.

0 = x^2 - 50x + 300

This is a quadratic. It will have 2 solutions.

a=1

b = - 50

c = 300

Put these into the quadratic equation.

It turns out that x has two values -- both plus

x1 = 42.03

x2 = 6.97

x1 + y1 = 50

42.03 + y = 50

y = 50 - 42.03

y = 7,97

(42.03 , 7.97)

====================

x2 + y2 = 50

6.97 + y2 = 50

y2 = 50 - 6.97

y2 = 43.03

(6.97 , 43.03)

Answer:

x ≈ 6.97, y ≈ 43.03; x ≈ 43.03, y ≈ 6.97

Step-by-step explanation:

System: x + y = 50, xy = 300

Alter 1st equation: y = 50 - x

Substitute: x(50 - x) = 300

Distribute: -x² + 50x = 300

Subtract: -x² + 50x - 300 = 0

Quadratic formula: x = (-50 ± √(2500 - 4 * -1 * -300))/(-2)

Simplify: x = (-50 ± √1300)/-2

Distribute: x = 25 ± (10√13)/-2

Simplify: x = 25 - 5√13 --> x ≈ 6.97, x = 25 + 5√13 --> x ≈ 43.03

Substitute: 6.97 + y = 50 --> y ≈ 43.03, 43.04 + y = 50 --> y ≈ 6.97

Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed.

The fraction of the class is right handed is 7/10

We have given that

80% of the second group are right-handed.

let's turn 80% into a fraction,

The fraction form of 80% can be calculated by dividing 80 by 100

So we get,

=8/10.

To get a common denominator let's turn

8/10 =4/5             .....(divide the numerator and denominator by 2)

Since they are both of equal size,

The first group would have 2/5 left-handed people and

The second 1/5 left-handed people.

Let's imagine that each group has 5 people in it.

There would be 10 people in total.

There is 1 person for each fifth so we can add now.
