A student wants to create a 2:1 scale drawing of the classroom. Is this an appropriate scale to use? Why or why not?

Answer:

AE = ED/////  A MIDPOINT DIVIDES A SEGMENT INTO TWO CONGRUENT SEGMENTS

AB = DC ///// OPPOSITE SIDES OF A RECTANGLE ARE CONGRUENT

<A IS A RIGHT ANGLE ///// THE INTERIOR ANGLES OF A RECTANGLE ARE RIGHT ANGLES

<D IS A RIGHT ANGLE ///// THE INTERIOR ANGLES OF A RECTANGLE ARE RIGHT ANGLES

<A = <D ///// ALL RIGHT ANGLES ARE CONGRUENT

TRIANGLES ABE = DCE ///// SAS

[tex]2 log(x) - log(x - 2) = 2 log(3) [/tex]

[tex] log(x {}^{2} ) - log(x - 2) = log(9) [/tex]

[tex] log( \frac{ {x}^{2} }{x - 2} ) = log(9) [/tex]

[tex] \frac{ {x}^{2} }{x - 2} = 9[/tex]

[tex] {x}^{2} = 9x - 18[/tex]

[tex] {x}^{2} - 9x + 18 = 0[/tex]

Answer:

$7.00

Step-by-step explanation:

Each pound cost $2 and we have 3 pounds which means that's $6:

3 • 2= 6

But then we have half a pound (1/2), well whats half of 2? the answer is 1 which means we add another dollar making that $7.00! :)

Answer:

sometimes, if their average angle is over 45 degrees

never are 2 obtuse angles summing to 180 degrees

always.  two 90 degree angles always sum to 180 which is a straight line

Answer:

y=11 * (18/5)

Step-by-step explanation:

y = kx

Where k is constant of proportionality

18 = k(5)

Hence k = (18/5)

For x = 11, y is....

Y = kx

Y= (18/5) * 11

Answer: 16

Step-by-step explanation:

It divides evenly into (w-4)^2.

Considering the situation described, we have that:

a) The Poisson distribution is used because we only have the mean.

b) There is a 0.0907 = 9.07% probability that there will be no defects.

c) There is a 0.2177 = 21.77% probability that there will be one defect.

d) There is a 0.3084 = 30.84% probability that there will be fewer than two defects.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

Item a:

The Poisson distribution is used because we only have the mean.

We have 0.8 defects per m² and 3 m², hence the mean is given by:

[tex]\mu = 3 \times 0.8 = 2.4[/tex]

Item b:

The probability is P(X = 0), hence:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-2.4}(2.4)^{0}}{(0)!} = 0.0907[/tex]

There is a 0.0907 = 9.07% probability that there will be no defects.

Item c:

The probability is P(X = 1), hence:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 1) = \frac{e^{-2.4}(2.4)^{1}}{(1)!} = 0.2177[/tex]

There is a 0.2177 = 21.77% probability that there will be one defect.

Item d:

The probability is P(X < 2), hence:

P(X < 2) = P(X = 0) + P(X = 1) = 0.0907 + 0.2177 = 0.3084.

There is a 0.3084 = 30.84% probability that there will be fewer than two defects.

Answer:

[tex]=\frac{60}{7}[/tex]

Step-by-step explanation:

Given the following question:

[tex]8\frac{4}{7}[/tex]

In order to convert the mixed number into an improper fraction multiply the denominator by the whole number and then add the numerator. While of course keeping the denominator the same.

[tex]8\frac{4}{7}[/tex]
[tex]8\frac{4}{7}=7\times8=56+4=60=\frac{60}{7}[/tex]

Answer:

Step-by-step explanation:

Are f(x)=x2 and g(x) =4/5x2 correctly written?

This answer assumes they are supposed to be:

f(x)=x^2 and g(x) = (4/5)x^2

If these revisions are correct, g(x) would produce values that are (4/5) of f(x).

The value of [tex]b[/tex] in the cubic polynomial is -4.

After a quick analysis, we find that given cubic function is equivalent to the following equivalence:

[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = (x-1)^{2}\cdot (x-2)[/tex]

[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = (x^{2}-2\cdot x + 1)\cdot (x-2)[/tex]

[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-2\cdot x^{2}+x-2\cdot x^{2}+4\cdot x-2[/tex]

[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-4\cdot x^{2}+5\cdot x -2[/tex]

After a quick observation, we conclude that the value of [tex]b[/tex] in the cubic polynomial is -4. [tex]\blacksquare[/tex]

Answer:

Let A(9, 9) & B(1, 4) are two point through which Line e passes.

Equation of e is given by

y - y1 = y2 - y1/ x2 - x1(x - x1)

or, y - 9 = 4-9/1-9 (x - 9)

or, -8y + 72 = -5x + 45

or, 5x - 8y + 27 = 0...........1.

Again,

consider C (1, 5) & D (9, 10) are other two points through with Line f pass through.

Also, eqn of f is,

y- 5 = 10-5/9-1 (x - 1)

or, 8y - 5 = 5x - 5

or, 5x - 8y =0 ...........2.

Let m1 and m2 are slopes between the lines.

Now, slope of 1. = - coef. of x/ coef. of y

= -5/-8 = 5/8 =m1

& slope of 2. = -5/-8 = 5/8 = m2

Since slopes of lines i. e. m1 = m2, so the lines are parallel to each other.

We are given the Indefinite integral ;

[tex]{:\implies \quad \displaystyle \sf \int \dfrac{dx}{x-x^{3}}}[/tex]

Take x common from denominator ;

[tex]{:\implies \quad \displaystyle \sf \int \dfrac{dx}{x(1-x^{2})}}[/tex]

Now , Put ;

[tex]{:\implies \quad \displaystyle \sf x^{2}=u}[/tex]

So that ;

[tex]{:\implies \quad \displaystyle \sf dx=\dfrac{du}{2\sqrt{u}}\quad and\quad x=\sqrt{u}}[/tex]

Now , putting the values ;

[tex]{:\implies \quad \displaystyle \sf \int \dfrac{1}{\sqrt{u}(1-u)}\times \dfrac{1}{2}\times \dfrac{du}{\sqrt{u}}}[/tex]

Now , as constant can be taken out of the integrand, so now ;

[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}\int \dfrac{du}{u(1-u)}}[/tex]

Using partial fraction decomposition, Rewrite the integral as ;

[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}\int \left(\dfrac{1}{u}+\dfrac{1}{1-u}\right)du}[/tex]

As Integrals follow distributive property, so breaking the integral into two integrals, and continuing the integration

[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}\left(\int \dfrac{1}{u}du+\int \dfrac{1}{1-u}du\right)}[/tex]

[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}\bigg\{log|u|+\dfrac{log|1-u|}{(-1)}\bigg\}+C}[/tex]

[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}log\bigg|\dfrac{u}{1-u}\bigg| +C}[/tex]

Putting value of u ;

Step-by-step explanation:

We are given that the circumference of a circle is 77 units and we need to find it's diameter . But let's recall that for any Circle with radius r , the circumference is given by 2πr . And diameter is double of radius i.e d = 2r , so we can write the circumference as 2r(π) i.e dπ . So , now here

[tex]{:\implies \quad \sf d\pi =77}[/tex]

[tex]{:\implies \quad \sf d\times \dfrac{22}{7}=77}[/tex]

[tex]{:\implies \quad \sf d=\dfrac{77\times 7}{22}}[/tex]

[tex]{:\implies \quad \sf d=\dfrac{\cancel{11}\times 7\times 7}{\cancel{11}\times 2}}[/tex]
