Answer:

Step-by-step explanation:

So given the three bits of information you can conclude a couple of things. The end behavior towards the right should be increasing and since there is only two turning points this means it was previously going down but had a turning point and starting going up, and before that it was going up and then started going down, those will be the two turning points. So on the left side it should be decreasing and the right side it should be increasing. The last peace of information tells you that at the second turning point, should be equal to 250k when it turned back up OR the y-intercept is 250k. Given all this information the answer should be the first graph in the first picture

The probability of rolling an even number first and an odd number second is 1/4.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability of rolling an even number first and an odd number second = (numbers that have the even number first and odd number second / total sample space)

9/36 = 1/4

Answer:

y = -5x - 11

Step-by-step explanation:

We are given that a line passes through the point (-3,4) and also has a slope of -5.

We want to write an equation of this line.

The equation of the line can be written in 3 different ways:

Since the question did not specify, any of these 3 options will be valid, however, the most common way to write the equation of the line is in slope-intercept form, so let's do it that way.

Because we are already given the value of the slope, we can immediately plug that into the equation.

Replace m with -5.

y = -5x + b

Now we need to find b.

As the equation passes through the point (-3, 4), we can use its values to help solve for b.

Substitute -3 as x and 4 as y.

4 = -5(-3) + b

Multiply

4 = 15 + b

Subtract 15 from both sides.

-11 = b

Substitute -11 as b in the equation.

y = -5x - 11

Answer: a = 2√3

First method (Pythagoras theorem):

a² + b² = c²

a² + 2² = 4²

a² = 16 - 4

a = √12

a = 2√3

Second method (sine rule):

opposite/hypotenuse = sin(x)

a/4 = sin(60)

a = 4sin(60)

a = 2√3

Third method (tan rule):

opposite/adjacent = tan(x)

a/2 = tan(60)

a = 2tan(60)

a = 2√3

Answer:

2√3

Step-by-step explanation:

From inspection of the given triangle:

As we cannot be sure that ΔABC is a right triangle since it is not marked as such, use the cosine rule to find the exact length of side a.

Cosine Rule

[tex]a^2=b^2+c^2-2bc \cos A[/tex]

where a, b and c are the sides and A is the angle opposite side a

Given:

Substitute the given values into the formula and solve for a:

[tex]\implies a^2=2^2+4^2-2(2)(4) \cos 60^{\circ}[/tex]

[tex]\implies a^2=4+16-16\left(\dfrac{1}{2}\right)[/tex]

[tex]\implies a^2=20-8[/tex]

[tex]\implies a^2=12[/tex]

[tex]\implies a=\sqrt{12}[/tex]

[tex]\implies a=\sqrt{4 \cdot 3}[/tex]

[tex]\implies a=\sqrt{4}{\sqrt{3}[/tex]

[tex]\implies a=2\sqrt{3}[/tex]

Therefore, the exact length of side a is 2√3.

To find out if ΔABC is a right triangle, use Pythagoras Theorem to solve for side a:

[tex]\implies a^2+b^2=c^2[/tex]

[tex]\implies a^2+2^2=4^2[/tex]

[tex]\implies a^2+4=16[/tex]

[tex]\implies a^2=12[/tex]

[tex]\implies a=\sqrt{12}[/tex]

[tex]\implies a=2\sqrt{3}[/tex]

As the measure of side a is the same as the solution found when using the cosine rule, we can conclude that ΔABC is a right triangle.

There's nothing particularly tricky about the limits of integration. The upper limit is a telescoping series converging to 2,

[tex]\displaystyle \sum_{n=1}^\infty \frac4{4n^2-1} = 2 \sum_{n=1}^\infty \left(\frac1{2n-1} - \frac1{2n+1}\right) \\\\ ~~~~~~~~ = 2 \left(\left(1-\frac13\right)+\left(\frac13-\frac15\right) + \left(\frac15 - \frac17\right) + \cdots\right)[/tex]

The lower limit reduces to 0 using the Riemann-Liouville definition of the fractional derivative. For [tex]q\in\Bbb Q[/tex], let

[tex]\displaystyle \frac{d^q}{dx^q} f(x) = \frac1{\Gamma(\lceil q\rceil-q)} \frac{d^{\lceil q\rceil}}{dx^{\lceil q\rceil}} \int_a^x (x-t)^{\lceil q\rceil-q-1} f(t) \, dt[/tex]

With [tex]a=0[/tex], [tex]q=\frac12[/tex] and [tex]\lceil q\rceil=1[/tex], it follows that

[tex]\displaystyle \frac{d^{1/2}}{dx^{1/2}} 1 = \frac1{\Gamma\left(\frac12\right)} \frac d{dx} \int_0^x (x-t)^{-1/2} \, dt = \frac1{\sqrt{\pi x}}[/tex]

Let

[tex]\displaystyle I = \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right)}{x^2-4x-1} \, dx[/tex]

Observe that

[tex]f(x) = \dfrac{2-x}{1+2x} = f^{-1}(x)[/tex]

is its own inverse, so by substituting [tex]\frac{2-x}{1+2x}\mapsto x[/tex], we get the equivalent integral

[tex]\displaystyle \int_0^2 \frac{\tan^{-1}(x)}{x^2-4x-1} \, dx[/tex]

We have the identity

[tex]\tan^{-1}(x) + \tan^{-1}\left(\dfrac{2-x}{1+2x}\right) = \tan^{-1}(2)[/tex]

so that

[tex]\displaystyle I + I = \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right) + \tan^{-1}(x)}{x^2-4x-1} \, dx[/tex]

[tex]\implies \displaystyle I = \frac{\tan^{-1}(2)}2 \int_0^2 \frac{dx}{(x-2)^2-5}[/tex]

The remaining integral is trivial,

[tex]\displaystyle \int_0^2 \frac{dx}{(x-2)^2-5} = \int_{-2}^0 \frac{dx}{x^2-5} \\\\ ~~~~~~~~ = \frac1{2\sqrt5} \int_{-2}^0 \left(\frac1{x-\sqrt5} - \frac1{x+\sqrt5}\right) \, dx \\\\ ~~~~~~~~= -\frac{\ln(2+\sqrt5)}{2\sqrt5} \\\\ ~~~~~~~~ = -\frac1{\sqrt5} \tanh^{-1}\left(\dfrac2{\sqrt5}\right)[/tex]

Then the integral we want is

[tex]I = \displaystyle \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right)}{x^2-4x-1} \, dx = \boxed{-\frac1{2\sqrt5} \tan^{-1}(2) \, \tanh^{-1}\left(\dfrac2{\sqrt5}\right)} \approx -0.357395[/tex]

Answer:

15 buses                   18 buses

--------------             = ---------------

795 passengers      x passengers

Using cross products

15 * x = 18 * 795

On the third day, the highest number of can of blue paint he can use is 2

On the third day, the highest number of can of yellow paint he can use is 3.

The ratio of blue paint to yellow paint can be determined by determining the simplest form of the paints used: 4 : 6 = 2: 3

Total blue paint cans used on the first and second day = 4 + 6 = 10

Blue paint cans remaining = 14 - 10 = 4

Since the angles of elevation of the top of two vertical towers is 45° & 60°, the ratio of the height of the towers is 0.58:1

Since the angles of elevation of the top of two vertical towers as seen from the middle point of the lines joining the foot of the towers are 45° & 60°.

The height of the tower, the line of sight and the ground form a right angled trangle

Let

Using trigonometric ratios, we have that

tanФ = h/d

= h/L/2

= 2h/L

So, h = LtanФ/2

= Ltan45°/2

= L/2 × 1

= L/2

Let

Using trigonometric ratios, we have that

tanФ' = h'/d

= h'/L/2

= 2h'/L

So, h' = LtanФ'/2

= Ltan60°/2

= L/2 × √3

= √3L/2

So, the ratio of the height of the towers is n = h/h'

= L/2 ÷ √3L/2

= 1/√3

= 1/1.732

= 0.577

The trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]

Since we have 4cos(-5B) sin3B

Using the trigonometric identity

sin(x + y) - sin(x - y) = 2cosxsiny

So, cosxsiny = [sin(x + y) - sin(x - y)]/2

Since we have 4cos(-5B) sin3B, comparing cos(-5B) sin3B with cosxsiny, we have

x = -5B and y = 3B

So, we have cos(-5B)sin3B = [sin(-5B + 3B) - sin(-5B - 3B)]/2

= [sin(-2B) - sin(-8B)]/2

=  [-sin(2B) - {-sin(8B)}]/2 [since sin(-2B) = -sin(2B)]

=  [-sin(2B) + sin(8B)]/2

= [sin(8B) - sin(2B)]/2

So, 4cos(-5B)sin3B = 4 × [sin(8B) - sin(2B)]/2

= 2[sin(8B) - sin(2B)]

So, the trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]

The domain of f(x) is all real numbers > than it equal to 3, for f(x) = 3/x + 2 - √(x - 3).

The domain of a function f(x) is the set of all real values of x, for which real f(x) exists.

In the question, we are asked to find the domain of the function f(x) = 3/x + 2 - √(x - 3).

To find the domain of f(x), we need to check the real values of x, for which real f(x) exists.

We check each part of f(x):

For 3/x, every x gives a real value except x = 0.

For 2, every x gives a real value as it is not dependent on x.

For √(x - 3), real values exist when x - 3 ≥ 0, as negative square roots are not real.

Therefore, after assessing each term, we can say that the domain for f(x) is x - 3 ≥ 0, or x ≥ 3.

Therefore, the domain of f(x) is all real numbers > than it equal to 3, for f(x) = 3/x + 2 - √(x - 3).

Given that, the original function is

and now the function is

When f(x)=0 then we can get by calculating that,

x=0

So, the f(x) function satisfied by point (0,0).

Now when g(x)=0 then by calculating that we get,

[tex](x-6)^2=0[/tex]

x-6 = 0

x = 6

So g(x) function satisfied by (6,0).

In geometrical words we can say that if we transform from f(x) to g(x) then (0,0) tranformed to (6,0).

That suggests that the function moves 6 unit right along X axis, which is towards positive X axis.
