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
How to find the ratio of the height of the towersSince 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
Height of first towerLet
h = height of first tower, d = distance of tower to middle point = L/2 where L = distance between tower and Ф = angle of elevation of tower from midpoint = 45°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
Height of second towerLet
h' = height of first tower, d = distance of tower to middle point = L/2 where L = distance between tower and Ф' = angle of elevation of tower from midpoint = 60°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
Ratio of the height of the towersSo, the ratio of the height of the towers is n = h/h'
= L/2 ÷ √3L/2
= 1/√3
= 1/1.732
= 0.577
≅ 0.58
So, the ratio of the height of the towers is 0.58:1

A line passes through the point (-3,4) and has a slope of -5. Find an equation of this line
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:
Slope-intercept form, which is written as y=mx+b, where m is the slope and b is the y intercept.Standard form, which is written as ax+by=c, where a, b, and c are free integer coefficients (but a and b cannot be 0, and a cannot be negative). Slope-point form, which is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope, and [tex](x_1, y_1)[/tex] is a pointSince 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

5. In 2011, Manitoba progressive income tax rates were 10.8% on the first $31,000, 12.75% on the next $36,000, anc
17.4% on any additional income. If your gross taxable earnings for the year were $85,000, what percentage of your
earnings did you pay in taxes?
Step-by-step explanation:
0 <= income <= 31000 : 10.8%
31000 < income <= 31000+36000 = 67000 : 12.75%
67000 < income < anything above 67000 : 17.4%
the total income is
$85,000
the taxes paid are
10.8% of 31000 = $3348
12.75% of 67000 - 31000 = 12.75% of 36000 = $4590
17.4% of 85000 - 67000 = 17.4% of 18000 = $3132
so, out of $85000 you paid

Answer:
Emily raised $37.50
Justin raised $57.50
Step-by-step explanation:
(Step 1)
Say "x" equals the amount of money Emily made and "y" equals the amount of money Justin made. You can set up an equation with both of these variables because we know that they made a combined $95.
x = Emily's earnings
y = Justin's earnings
Emily + Justin = 95
x + y = 95
(Step 2)
The fact that there are two variables makes it difficult to find how much each person made individually. However, we can eliminate the "y" variable when we remember that Justin made $20 more than Emily. Now, we can substitute "x + 20" in for "y".
x + 20 = y
x + y = 95
x + (x + 20) = 95
(Step 3)
Finally, we can solve for the "x" variable.
x + (x + 20) = 95
2x + 20 = 95 <------ Combine like terms
2x = 75 <------ Subtract 20 from both sides
x = 37.5 <------- Divide both sides by 2
(Step 4)
Since we know the value of "x", we can plug it into one of the equations to find the value of "y".
x + 20 = y
37.5 + 20 = y
y = 57.5
Answer:
Emily raised $37.5 and justin raised $57.5

What is the slope of the line shown below?
Answer:
(1/2)
Step-by-step explanation:
From one point, if you go up one and over 2 you will get exactly one block up than from your initial point. And since the graph is pointing down on left side, that means it's positive.
[tex]\displaystyle \rm \int_{1 - \sqrt{\pi x} \large \frac{ {d}^{ {1/2 }} }{ {dx}^{1/2} } \small(1) }^{ \sum \limits_{n = 1}^ \infty \frac{4}{4 {n}^{2} - 1 } } \frac{arctan( \frac{2 - x}{1 + 2x}) }{ {x}^{2} - 4x - 1} dx[/tex]
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]
Need the answer for number 3 please!!
Answer: No
Step-by-step explanation:
The graph is increasing, yet as p increases, the value of 100/p decreases, meaning that the graph should be decreasing.
Participants in a darts tournament get 4 points
if they hit the red circle, 1 point if they hit the
blue circle, and no points if they miss both
circles. Each participant has 4 darts. How
many different scores are possible if everyone
gets at least one point?
Using the Fundamental Counting Theorem, it is found that 80 different scores are possible if everyone gets at least one point.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
There are 4 darts, and for each dart 3 possible scores, hence:
[tex]n_1 = n_2 = n_3 = n_4 = 3[/tex]
Hence the number of possible scores, removing the one score with zero points on all four rounds, is:
N = 3 x 3 x 3 x 3 - 1 = 80.

What is the range of f(x)?
O {f(x)
O {f(x)|-∞
O {f(x)|4
O {f(x)|0sf(x)<∞}
Answer:
best ans is { f(x)| –∞ < f(x) ≤ 4}
Step-by-step explanation:
usually to find the range of a fn, u need to see what the value can be. the graph show only a small range of x values. but u can see f(x) is definitely < 4. so the ans is { f(x)| –∞ < f(x) ≤ 4}

From a group of 6 men and 4 women, how many committees of 2 men and 3 women can be formed?
The number of ways committees of 2 men and 3 women can be formed is 60.
What is Permutation and Combination ?The method of arranging objects in order is called Permutation and the method of selecting things from a group of objects such that the order doesn't matter is called Combination.
Total Men = 6
Total Women = 4
Committee should consists of 2 men and 3 women
2 men from 6 men can be selected in [tex]\rm ^6 C _2[/tex] ways
3 women from 4 women can be selected in [tex]\rm ^4C_3[/tex] ways
The number of ways committees of 2 men and 3 women can be formed can be determined by Multiplication Principle
[tex]\rm ^6 C _2[/tex] * [tex]\rm ^4C_3[/tex]
15 * 4
= 60 ways
Therefore the number of ways committees of 2 men and 3 women can be formed is 60.
