Your friend's rate of change in elevation is 0.5 feet per minute more than your rate.

Rate of change in elevation = elevation of distance/time

The elevation of 720 feet to an elevation of 750 feet in 30 minutes.

Your rate of change in elevation = 750 - 720 / 30

Your rate of change in elevation = 30 / 30

Your rate of change in elevation = 1 foot per minute

Your friend in-line skates from an elevation of 600 feet to an elevation of 690 feet in one hour.

Your friend's rate of change in elevation = 690 - 600 / 60

Your friend's rate of change in elevation = 90 / 60

Your friend's rate of change in elevation = 1.5 feet per minute

The difference in rate of change in elevation = 1.5 - 1 = 0.5 feet per minute

Thus, your friend's rate of change in elevation is 0.5 feet per minute more than your rate.

The functions f(g(x)) and g(f(x)) are not inverse functions

From the question, we have the following parameters that can be used in our computation:

f(x) = x³

g(x) = 1/3x

Calculate the composite function f(g(x)).

So, we have

f(g(x)) = (1/3x)³

This gives

f(g(x)) = 1/27x³

Calculate the composite function  g(f(x)).

So, we have

g(f(x)) = 1/3(x³)

This gives

g(f(x)) = 1/3x³

The functions f(g(x)) and g(f(x)) are not the same

Hence, they are not inverse functions

The equation can be written as - 8x + 12 = 8x + 12 which means it has infinite solutions. So, there are infinite values of [x] for which parameters are equal.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a square and a triangle as shown.

For equal perimeter -

4(2x + 3) = (2x - 2) + 2(3x + 7)

8x + 12 = 2x - 2 + 6x + 14

8x + 12 = 8x + 12

The equation can be written as -

Using a graphing calculator to plot the vertices, the points plotted gave a triangle

This can be said to be the location of the endpoints in a given square. The vertices of a square must be equidistant from one another. This is a place in geometry where common endpoints of two or more rays or line segments meet. Thus, in a square, the vertex is the point where two sides meet. It is each corner of a square. Thus, each square has 4 vertices.

In this problem, we have to use a graphing calculator and plot each points

In doing so, we have A(1, 2), B(4, 2) and C(4, -1)

Answer:

subtract the equations

Step-by-step explanation:

the second answer option is nonsense.

if the equations really have exactly one solution, then it is impossible to make them equal.

if 2 equations can be made equal, that means they have infinitely many solutions.

the other answers have all some merit.

but the last one (subtract the equations) is the best one.

it means

y = 2x + 4

- y = 3x - 6

------------------

0 = -x + 10

after adding x to both sides we get

x = 10

with that we use any of the 2 basic equations to get y :

y = 2x + 4 = 2×10 + 4 = 24

this worked right away, because the y terms have the same coefficients (1). so, by subtracting one equation from the other we eliminate y as variable and can solve for x.

if that was not the case like in

2y = 4x + 8

y = 3x - 6

we would have to do some transformation or manipulation to bring the system into a form like here in the beginning.

and the first and the third answer option would apply.

The dimensions of the wooden block are 14cm tall, 4cm long and 3 cm wide.

In three dimensional space prism is a polyhedron where two ends are similar.

Given that volume of rectangular prism is 168 cubic centimeters.

And the wooden block is 2x cm tall, (x-4) cm wide and (x-3) cm long.

And also given that a wooden block in a set of building blocks is a rectangular prism.

That means,

Volume of wooden block = Volume of rectangular prism = 168 cm³

Volume of wooden block ;

length × width × height = 168 cm³

Substituting given values in above expression,

2x (x-3) (x-4) = 168 cm³

2x (x²-7x + 12) = 168 cm³

2x³ - 14x²+ 24x = 168 cm³

Simplifying the above equation;

2x³ - 14x²+ 24x- 168 = 0

x³ - 7x²+ 12x- 84 = 0

The factor of above cubic equation is x = 7.

Now the 2x = 14 , x-3 = 4, x-4 = 3.

Therefore the dimensions of the wooden block are 14cm tall, 4cm long and 3 cm wide.

Answer: $5580

The formula for compound interest is:

A = P(1 + r/n)^nt

where A is the final amount, P is the initial principal (the amount you deposited in the account), r is the annual interest rate (8% in this case), n is the number of times the interest is compounded per year (12 times per year if the interest is compounded monthly), and t is the number of years the money is invested (5 years in this case).

Plugging in the values from the problem, we get:

A = $3000(1 + 0.08/12)^(12*5)

= $3000(1.0067)^60

= $3000*1.86

= $5580

So, after 5 years, you will have $5580 in the account if you deposit $3000 and earn 8% interest compounded monthly.

The value of amount after 5 years is,

⇒ A = $4,380

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

You deposit $3000 in an account earning 8% interest compounded monthly.

Hence, The value of amount after 5 years is,

⇒ A = 3000 [ 1 + 0.08]⁵

⇒ A = 3000 × 1.08⁵

⇒ A = 3000 × 1.46

⇒ A = $4,380

Thus, The value of amount after 5 years is,

⇒ A = $4,380

The majority of the observations are centred around the middle peak of the normal distribution, which is a continuous probability distribution that is symmetrical around its mean. 

The normal distribution is a continuous probability distribution with symmetry around its mean, a central peak around which the majority of observations cluster, and a tapering off of probabilities in both directions for values that are farther from the mean.

The data given from the graph proves that Catherine and Ana's suspicions were correct and the athletes at their school do indeed have a quicker reaction time than other students at their school. The average reaction time for the athletes ranges from 240 - 300, while the normal student's reaction time ranges from 260 - 330. There still should be more experiments to test this theory to get more detailed and accurate results because there are still athletes that have the same reaction time as normal students and the dot away from the boxes shows that there is a athlete that has a slower reaction rate than all of the  normal students. So it is safe to say there is indeed a difference in reaction times, but not a drastic one.

To find the maximum height that the pumpkin reaches, we can set the derivative of the equation equal to 0 and solve for x. The derivative of y = 12 + 105x - 16x^2 is y' = 105 - 32x. Setting y' = 0, we get:

0 = 105 - 32x

32x = 105

x = 105/32

The maximum height is reached when x = 105/32 seconds. To find the maximum height, we can plug this value of x into the original equation:

y = 12 + 105(105/32) - 16(105/32)^2

= 12 + 1053.28125 - 163.28125^2

= 12 + 342.8125 - 106.25

= 248.5625

The maximum height that the pumpkin reaches is 248.5625 feet.

To find the number of seconds it takes for the pumpkin to hit the ground (when its height is 0), we can set y = 0 in the original equation and solve for x:

0 = 12 + 105x - 16x^2

16x^2 - 105x + 12 = 0

(4x - 3)(4x - 4) = 0

The solutions to this equation are x = 3/4 and x = 4/4. The second solution is extraneous, since it represents the time at which the pumpkin was launched (when x=0, y would be 12 feet, not 0 feet). Therefore, the number of seconds it takes for the pumpkin to hit the ground is x = 3/4 seconds.

What is Pythagoras theorem?

The pythagorean theorem or Pythagoras' theorem may be a elementary relation in geometry between the 3 sides of a triangle.

So, PR² = PQ² + QR²

PR² = 14² + 9²

PR² = 196 + 81

PR = √277

In short,  approximate length of rod PR would be 16.64 Feet.

B) Again, Use the Pythagoras Theorem,  

c² - a² = b²

18² - 14² = b²
