John travelled 280 kilometres in the first distance and 250 kilometres in the second distance.

This question shows the case of John, who drove at constant speed his car on two roads. The travelled distance (s), in kilometers, is equal to the following formula:

s = v × t

Where:

v - Speed, in kilometers per hour.

t - Time, in hours.

The total time (T), in hours, is found by means of the following expression:

T = t₁ + t₂

T = x₁ / v₁ + x₂ / v₂

Where:

x₁ - Distance traveled in the first road

x₂ - Distance traveled in the second road.

v₁ - Speed taken in the first road.

v₂ - Speed taken in the second road.

T - Total time.

If we know that v₁ = 100 km / h, v₂ = 80 km / h, x₂ = 530 km - x₁ and T = 6 h, then the first distance is:

(530 - x₁) / 100 + x₁ / 80 = 6

[80 · (530 - x₁) + 100 · x₁] / 8000 = 6

42400 - 80 · x₁ + 100 · x₁ = 48000

20 · x₁ = 5600

x₁ = 280 km

And the second distance is:

x₂ = 530 km - 280 km

x₂ = 250 km

Answer:

The height of the cliff is 408.1 m

Step-by-step explanation:

To find the height of the cliff given a stone is thrown downward from the top of a cliff at 24m/s and hits the ground 7 seconds later, use constant acceleration equations (SUVAT).

Constant Acceleration Equations (SUVAT)

[tex]\boxed{\begin{array}{c}\begin{aligned}v&=u+at\\\\s&=ut+\dfrac{1}{2}at^2\\\\ s&=\left(\dfrac{u+v}{2}\right)t\\\\v^2&=u^2+2as\\\\s&=vt-\dfrac{1}{2}at^2\end{aligned}\end{array}} \quad \boxed{\begin{minipage}{4.6 cm}$s$ = displacement in m\\\\$u$ = initial velocity in ms$^{-1}$\\\\$v$ = final velocity in ms$^{-1}$\\\\$a$ = acceleration in ms$^{-2}$\\\\$t$ = time in s (seconds)\end{minipage}}[/tex]

Note: When using SUVAT, assume the object is modeled as a particle and that acceleration is constant.

List the given variables, taking downwards as positive:

Select the SUVAT equation with s, u, a and t in it:

[tex]s=ut+\dfrac{1}{2}at^2[/tex]

[tex]\begin{aligned}\textsf{Substitute the values}: \quad s&=24(7)+\dfrac{1}{2}(9.8)(7)^2\\s&=168+240.1\\s&=408.1\; \sf m \end{aligned}[/tex]

Therefore, the height of the cliff is 408.1 m.

The total area filled by a flat (2-D) surface or an object's form is referred to as the area and the required area of the metal frame is 93.76x² unit square.

The area is the total area occupied by a flat (2-D) surface or the form of an object.

Create a square on paper by using a pencil.

Two dimensions make it up.

A form's area on paper is the space it takes up.

So, given, a square metal frame encircles a circular mirror.

The mirror has a 4x radius.

The metal frame's side length is 12x.

According to the basic formula for the area of a circle and a square:

area of a circle = pi * radius * radius

Square Area = Side * Side

In the given situation:

Mirror's Area = pi * 4x * 4x = pi * 16x² = 50.24x

Squared mirror's Area = 12x * 12x = 144x²

The area of the metal frame is the sum of the areas of the squared and round mirrors.

Metal frame area =   144x² -  50.24x²

Metal frame size = 93.76x²

Every vector spaces, iff:e→eis an idempotent linear map as E= Kcr(f) + Im(f)

What is Linear Map?

A linear map is a mapping in mathematics, more specifically in linear algebra. It is also known as a linear transformation, vector space homomorphism, or, in some cases, a linear function. that maintains the operations of vector addition and scalar multiplication between two vector spaces

Given that,

F : E → E is an idempotent linear map i.e FoF =F

F is an idempotent, then for any W in the image of F statistics

W = F(x)

for some x = E

Then F(w) = FoF(x)

F(x)=(W)----- (A)

So F is indeed a projection to Im(F) as a subspace of v

also , Kcr(F) + Im(F) =0

Because if x∈Kcr(f) + Im------(B)

then f(x) = 0 and

f(t)=x for some x∈E

FoF (t) = 0

f(t)=x

x=0

also from A we have

f(x)-w=0

f(x) -f(w)=0

f(x-w)=0

x-w=t

where t∈Kcr (F)

X = W+T

here x is arbitrary

E = Kcr + Im f ------(C)

From (B) and (C) we have E = Kcr(f) + Im (f)

Since E= Kcr(f) + Im, every vector space is an idempotent linear map (f)

Answer: To calculate the compound interest and amount for a given principal, interest rate, and time period, we can use the formula:

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

where:

A = the final amount (principal + interest)

P = the principal (initial investment)

r = the annual interest rate (expressed as a decimal)

n = the number of times the interest is compounded per year

t = the number of years the investment is held

a. Principal = $5,900; Time = 2 years; Rate = 14%

n = 2 (since the interest is compounded half-yearly)

t = 2

r = 0.14

A = 5900(1+0.14/2)^(22)

A = 5900(1+0.07)^4

A = 59001.07^4

A = 5900*1.298844

A = 7,638.21

So the final amount, including interest, would be $7,638.21

b. Principal = $7,800; Time = 6 years; Rate = 18%

n = 2 (since the interest is compounded half-yearly)

t = 6

r = 0.18

A = 7800(1+0.18/2)^(26)

A = 7800(1+0.09)^12

A = 78001.09^12

A = 7800*2.05832

A = 16,093.32

So the final amount, including interest, would be $16,093.32

Please note that the above calculations are based on the compound interest formula and the assumption that the interest is compounded half-yearly, without taking into account any fees, taxes or any other associated cost.

a) The percentage of individuals who sleep between 4.5 and 9.3 hours is 75%.

b) By using Chebyshev's theorem, the percentage of individuals who sleep between 3.9 and 9.9 hours is 84%.

c) Using the empirical rule, the percentage of individuals who sleep between 4.5 and 9.3 hours day is 95%. But according to Chebyshev's theorem, this percentage is equals to 75%.

According to Chebyshev's theorem, the proportion of any distribution that lies within k standard deviations of the mean is at least equals to 1 − 1/k² , where k is a positive number, k> 1.

a) The average sleep hours per night is = 6.9 hours and standard deviation = 1.2 hours. Therefore, individuals who sleep between 4.5 and 9.3 hours are ± 2.4 hours or 2 standard deviations from the mean. Hence, k = 2. Using above theorem, the proportion of individuals who sleep between 4.5 hours and 9.3 hours = 1 - 1/2² = 1 - 1/4 = 0.75. Hence, the percentage of individuals who sleep between 4.5 hours and 9.3 hours

= 75%.

b) Again, the individuals who sleep between 3.9 and 9.9 hours are ±3 hours or 2.5 standard deviations from the mean. Hence, k = 2.5.

By Chebyshev's theorem, the proportion of individuals who sleep between 3.9 hours and 9.9 hours = 1 - 1/(2.5)² = 0.84 or 84 %.

c) The empirical rule is a rule-of-thumb used in statistics to forecast the behaviour of normally distributed data. Main points of Empirical rule:

The assumption here is that the number of hours of sleep follows a bell-shaped distribution i.e., the data are assumed to be normally distributed and therefore Empirical rule is applicable. As we see in individuals who sleep between 4.5 and 9.3 hours day are 2 standard deviations away from the mean. Therefore, by Empirical rule, the percentage is equals to 95% in this case. Thus, the conclusion is as per Empirical rule 95% of the individuals sampled in the national survey sleep between 4.5 and 9.3 hours. Whereas Chebyshev's theorem estimates that 75% individuals sleep between 4.5 and 9.3 hours.

The reasonable values for the domain of f(x) is D = {x ∈ W | x ≤ 50}

The domain of a function is the complete set of possible values of the independent variable.

Given that, f(x) = x, where x is the number of people seated on the bus that has a maximum seating capacity of 50

Let us assume the maximum number of people that can sit on a bus is 50.

We know that, domain is all the possible values of x in set notation.

First, state the type of numbers that can be the number of people seated.

Since you cannot have a negative number of people, you cannot have a part of a person, but you can have 0 people, so the type to be included is W whole.

Therefore, the domain can be defined as, D = {x ∈ W | x ≤ 50}

That mean, the domain is x is an element of all whole numbers, x is less than or equal to 50.

Hence, the reasonable values for the domain of f(x) is D = {x ∈ W | x ≤ 50}

The value of 5/12 in decimal is 0.4167 and in percent is 41.67% .

The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 of 100 questions correctly on a test (75/100).

The division is shown by the fractional bar between the "part" and the "whole." By dividing the numerator by the denominator, any fractions may be transformed into decimals. For instance, the fraction 45 denotes the ratio of 4 to 5, or 4/5. By dividing 4 by 5, this fraction may be changed into a decimal.

5/12 can be converted into decimal by dividing 5 by 12 we get 0.4167

Rounding to six decimal places, the estimated area is 0.719638.

The midpoint rule for estimating the area under a curve involves dividing the interval of integration into n subintervals and using the heights of rectangles with width equal to the subinterval width to approximate the area under the curve.

Let's divide the interval [0, 2] into 4 subintervals, each with width 0.5. Then the midpoints of the subintervals are: x1 = 0.25, x2 = 0.75, x3 = 1.25, x4 = 1.75

Using the midpoint rule, the estimated area is given by the sum of the areas of the rectangles:

A = 0.5 * f(0.25) + 0.5 * f(0.75) + 0.5 * f(1.25) + 0.5 * f(1.75) where f(x) = e^(-3x²).

Substituting the values of f(x) into the above expression and evaluating, we get:

A = 0.5 * e^(-3 * 0.25²) + 0.5 * e^(-3 * 0.75²) + 0.5 * e^(-3 * 1.25²) + 0.5 * e^(-3 * 1.75²)

= 0.5 * e^(-0.1875) + 0.5 * e^(-2.25) + 0.5 * e^(-3.9375) + 0.5 * e^(-6.0625)
