The equation of a curve which intersects at right angles every curve of the family y = 1 / x + k is: y = x^3 / 3. The correct option is D.

The given equation:

y = 1/x + k.

And since y’ = –1 / x^2

So, the desired curve satisfies:

y’ = x^2

From the given equation we get:

dy / dx = –1 / x^2

any suitable function would have the negative reciprocal slope, so:

df / dx = x^2 / 1 = x^2

So, f(x) = x^3 / 3

Hence, the equation that intersects at right angles of  y = 1 / x + k is y = x^3 / 3.

James can conclude about lack of carbon-14 is  ; ( E ) Without carbon-14, James can use relative dating to estimate the age of the fossil.

Relative dating, while it will not give an exact age, can estimate the age of the fossil. James could take a look at the relative order of past events and estimate the age of the fossil that way.

It is important to know that all animals have carbon-14. Carbon 14 is in the air in carbon dioxide molecules, which animals produce through cellular respiration.

James can utilize relative dating, which can be used as a substitute to determine the age of fossils in the absence of Carbon-14, which is essential for Carbon dating, as Carbon-14 is not present in the animal fossils he is studying.

A scientific method of identifying an object's age in relation to another is called relative dating ( i.e. determining the relative order of events ).

We may thus draw the conclusion that James can determine the age of the fossil using relative dating in the absence of carbon-14.

You can use a compass and set its angle such that it the radius of the circle that it will draw is less than that of WX's length but longer than its half. Use it to make 4 arcs.

Making 4 arcs (2 arcs up and down from W and 2 arcs up and down from X which intersect the previous two arcs) with the circle of radius smaller than the length of  WX will give two points on a perpendicular bisector.

How to find the perpendicular bisector of a line segment with the help of a compass and a straightedge?

The construction steps are as follows:

Let the line segment to be bisected(divided into two equal parts) by a perpendicular line(that perpendicular bisecting line is called the perpendicular bisector of the given line segment) be WX

Take a compass and set its radius length smaller than the length of WX and longer than half of WX

Put the tip of the compass on W and make an arc upside of WX

Now make an arc downside of WX

Repeat the above two steps but now with the tip being on X such that two new arcs intersect the previous two arcs.

Use a straightedge and join both the points of intersection of arcs.

The obtained line is the perpendicular bisector of the line segment WX

Using the above method, we get the perpendicular bisector of WX  shown in the below-attached figure.

Thus,

Absolute value is a mathematical term used to describe the distance between a number and zero on a number line. It is written in algebraic form as |x|.

The absolute value of a number is always positive, even if the number itself is negative. For example, the absolute value of -5 is 5, and the absolute value of 5 is also 5.

When graphed on a number line, the absolute value of a number is the distance between that number and zero. Positive numbers are found on the right side of the number line, and negative numbers are found on the left side. The absolute value of a number is the same regardless of which side of the number line it is located.

Absolute value can be used to compare the distance between two numbers on a number line. For example, the absolute value of 6 minus the absolute value of 3 is equal to the absolute value of 3 minus the absolute value of 6. This is because the distance between the two numbers is the same regardless of the order of subtraction.

Absolute value can also be used to solve equations.

Answer:

Manish covers more distance. He covers 960m whereas Santosh only covers 480m

Step-by-step explanation:

First we compute the perimeter of the square track

Perimeter of a square of side a = 4a

Here a = 80m

Perimeter of the square of side 80 =>  4 x 80 = 320 m

Since Manish runs 3 times around it, total distance covered = 3 x 320 = 960

The perimeter of a rectangle with length L and breadth B = 2(L + B)

So perimeter of the rectangular track = 2(80 + 40) = 2 x 120 = 240

Since Santosh ran twice around this, total distance covered = 2 x 240 = 480

When he is 10 feet from the base of the light, the rate at which the tip of his shadow moves is 10ft/s, and when he is 10 feet from the base of the light, the rate at which the length of his shadow changes is 4ft/s.

Given, the height of a man = 6 feet

Height of light = 15 feet

Rate of walk by man, dx/dt = 5 feet per second.

a) we have to find the rate at which the tip of his shadow is moving when he is 10 feet from the base of the light.

By using ratio of similar triangles,

15/y = 6/(y - x)

On cross multiplication,

15(y - x) = 6y

15y - 15x = 6y

15y - 6y = 15x

9y = 15x

Dividing by 3 on both sides,

3y = 5x

On differentiating both sides with respect to t,

3(dy/dt) = 5(dx/dt)

dy/dt = (5/3)(dx/dt)

dy/dt = (5/3)(6)

dy/dt = 30/3

dy/dt = 10 ft/s

Therefore, the rate at which the tip of his shadow is changing is 10 ft/s.

b) we have to find the rate at which the length of his shadow is changing when he is 10 feet from the base of the light.

Length of shadow, BD = y - x

Rate of change of shadow is calculated by differentiating length with respect to time.

d(BD)/dt = dy/dt - dx/dt

d(BD)/dt = 10 - 6

= 4 ft/s

Therefore, the rate at which the length of his shadow is changing is 4 ft/s.

Thus, when he is 10 feet from the base of the light, the rate at which the tip of his shadow moves is 10ft/s, and when he is 10 feet from the base of the light, the rate at which the length of his shadow changes is 4ft/s.

Step-by-step explanation:

In order to write an equation of the line in slope-intercept form, we first have to look at the equation:

y = mx + b

We have m, the slope, which is -3/4, and we have our y and x values, so in order to find b, we need to plug the other values in and solve for b

(-4,3)

y = 3

x = -4

m = -3/4

y = mx + b

(3) = [tex](\frac{-3}{4} )[/tex](-4) + b

3 = -3 + b

6 = b

So, equation of the line in slope-intercept form that passes through point (-4,3) and has a slope of -3/4, is y = -3/4x + 6

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

Given that,

A car is 5.5 ft long. A truck is 15% longer than the car.

Length of car = 5.5 feet

Length of truck = 5.5 + (15% × 5.5)

                         = 5.5 + [(15/100) × 5.5]

                         = 5.5 + (0.15 × 5.5)

                         = 5.5 + 0.825

The standard form of the equation of a line is:

y = mx + b

Where m is the slope of the line and (x,y) is a point on the line. We know that the line passes through the point (4, -11) and has a slope of 3/4.

We can use the point-slope form to find the equation of the line:

y - y1 = m(x - x1)

Where (x1, y1) is the point on the line and m is the slope.

Substituting in the given information we get:

y - (-11) = (3/4)(x - 4)

Simplifying the equation we get

y = (3/4)x + (33/4)

This is the equation of the line in standard form.
