A car's odometer measures distance to the nearest 0.1 miles. Which is the
most appropriate way to report the distance driven using the car's odometer?

The length of the other two sides are 4m and 5m

Using the Pythagorean theorem, we have that the square of the hypotenuse sides is equal to the sum of the squares of the other two sides of the triangle

This is represented as;

x² = y² + z²

From the information given, we have that;

z = 3m

x = x + 1

y = x

Substitute the values, we get

(x + 1)² = x² + 3²

Find the squares

(x + 1) ² = 9 + x²

expand the bracket

(x + 1) ( x + 1) - x² = 9

x² + x + x + 1 - x² = 9

collect like terms

2x = 8

x = 4

Then,

x + 1 = 5

x = 4

Hence, the values are 4m and 5m

Using percentages we know that 106 people stated they didn't think these questions seriously interrupted their ability to do their jobs.

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.

Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it.

A% is a number that has neither dimensions nor a defined unit of measurement.

The percentage can be calculated by dividing the value by the total value and multiplying the result by 100.

(Value/Total Value)100% is the formula for calculating percentages.

So, the percentage of people who answered the questionnaire is 66%.

That will be,

= 400/100 * 66

= 264

Of the 264 respondents, 40% said that they did not feel that these questionnaires significantly disrupted their workday.

= 264/100 * 40

= 105.6

= 106

Therefore, using percentages we know that 106 people stated they didn't think these questions seriously interrupted their ability to do their jobs.

Nikhil has been with the company for 24 years, while Mae has been there for 4 years.

Option C is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 2 = 8 is an equation.

We have,

Number of years Nikhil worked =  x

Number of years Mae worked =  y

x = 6y ______(1)

x = 8 + 4y ______(2)

Substituting (1) in (2)

6y = 8 + 4y

Subtract 4y on both sides.

6y - 4y = 8

2y = 8

Divide 2 into both sides.

y = 4

Now,

x = 6y

x = 6 x 4

x = 24

Answer:

p = -6, 7    

Step-by-step explanation:

To find the solutions to the equation p^2 = p + 42, we are going to need to solve for p. So, let's do just that!

p^2 = p + 42     [Subtract p^2 from both sides]

0 = -p^2 + p + 42     [Factor out the -]

0 = - ( p^2 - p - 42 )     [Factor p^2 - p - 42]

0 = - ( p + 6 ) ( p - 7 )     [Set both pair of parentheses equal to 0}

p + 6 = 0

The value of distance cover is, 1/4 miles.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Driving speed = (s - 4) / (s²-9s+20)

And, Time = (s - 5) / 4

Now, We know that;

⇒ Speed = Distance / Time

⇒ Distance = Speed × Time

Substitute the given values, we get;

⇒ Distance = (s - 4) / (s² - 9s + 20) × (s - 5) / 4

⇒ Distance = (s - 4) / (s² - 5s - 4s + 20) × (s - 5) / 4

⇒ Distance = (s - 4) / (s (s - 5) - 4 (s - 5)) × (s - 5) / 4

⇒ Distance = (s - 4) / (s - 4) (s - 5) × (s - 5) / 4

for the line of best fit, A graph's nodes are connected by a mathematical concept known as the line of greatest fit. It is a kind of linear regression that uses scatter data to determine how to best define the relationship between the dots.

A change in the value of X causes a change in the value of the equation, which is written as Y on X.

X on Y is the equation, and the deviation of the Y variable determines how the X variable changes.

The volume is found using cylindrical shells and rotating the region bounded by xy = 3, x = 0, y = 3, and y = 5 about the x-axis.

To find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis, we will use the method of cylindrical shells. First, we need to draw the graphs of the functions given. The graph of xy = 3 is a parabola, x = 0 is a vertical line, y = 3 is a horizontal line, and y = 5 is also a horizontal line. The region bounded by these curves is the area between x = 0, y = 3, and y = 5 and xy = 3. Next, we need to find the area of the cylindrical shell. The area of the shell is given by 2πrh, where r is the radius of the circle and h is the height of the shell. The radius of the circle is the distance from the x-axis to the curve, which in this case is x. The height of the shell is the difference between the upper and lower limits of the integral, which in this case is y2 - y1. We can then integrate the area of the shell over the range of x and y values to get the volume. The integral is ∫[0, 3]∫[3, 5]2π(x)(y2 - y1)dxdy. Finally, we can evaluate the integral to get the volume of the solid.

The volume of the solid is 17.5 . In general, finding the volume of a solid of revolution involves finding the volume of each infinitesimal cylindrical shell.

To find the volume of the solid obtained by rotating the region bounded by the curves y = x + 1, y = 0, x = 0, and x = 5 about the x-axis, we can use the method of cylindrical shells. The volume of the solid is given by the formula:

V = ∫ 2πrh dr

Where r is the radius of the cylindrical shell, h is the height of the shell, and dr is the incremental change in the radius as we move from one shell to the next. The radius of the cylindrical shell is equal to the distance from the line of rotation (in this case, the x-axis) to the point on the boundary curve that is vertically above the point where the shell intersects the x-axis.

In this case, the boundary curves are y = x + 1 and y = 0. For the interval 0 < x < 5, the height of the cylindrical shell is given by x + 1, and the radius of the shell is x. Therefore, the volume of the solid is given by:

V = ∫ 0 to 5 2π(x)(x + 1) dx = 17.5

The units of volume would be cubic units, determined by the units used for the variables x and π.

The choice of the method of integration, either by using disks/washers or cylindrical shells, depends on the geometry of the region being rotated and the axis of rotation.

The tautology states that if either P(x) or Q(x) is true for some x in set Z, then the other statement, either P(x) or Q(x), must also be true. It follows that if either P(x) or Q(x) is false, then the other statement must also be false.

The initial height of the rocket is 24 metres, the rocket hit the ground in 0.88 seconds and the height of the rocket after 4 seconds is 24 metres.

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The initial height of the rocket is given by the value of h when t = 0:

h(t)=-4t² + 16t + 24

h(0)=-4(0)² + 16(0) + 24

h(0)=24

So the initial height of the rocket is 24 metres.

The rocket will hit the ground when its height is 0 metres, so we can set h = 0 in the equation and solve for t:

0 = -4t²+ 16t + 24

-4t² + 16t + 24 = 0

t=-0.88 seconds

So the rocket will hit the ground after approximately 0.88 seconds.

The height of the rocket after 4 seconds is given by:

h(4)== -4(4)²+ 16(4) + 24

=-64+64+24

=24

So the height of the rocket after 4 seconds is 24 metres.
