Answer:

559.2 yards.

Step-by-step explanation:

Let the height of the mountain be x yards and the distance from the second location to the base of the mountain be y yards.

Then we have the equations:

tan 27 = x/y

tan 23 = x / (220 + y)

From the first equation  y =  x/ tan27 so substituting in the second one we have:

tan 23 =  x / (220 + x / tan 27)

Cross multiply:

x = 220 tan23 +  x tan 23 / tan 27

x =  93.384 + 0.833 x

x - 0.833x = 93.384

x = 93.384 / 0.167

x = 559.2 yards to 1 dec place (answer).

ANSWER

B. 13cm

EXPLANATION

The radius of the circle becomes the hypotenuse of the right triangle formed.

We can use the Pythagoras Theorem to obtain,

AC²+CY²=r²

This implies that,

r²=5²+12²

r²=25+144

r²=169

Take positive square root to get;

r=√169

r=13

AB and AC are two equal chord of a circle, therefore the centre of the circle lies on the bisector of ∠BAC.

OA is the bisector of ∠BAC.

Again, the internal bisector of an angle divides the opposite sides in the ratio of the sides containing the angle.

P divides BC in the ratio 6:6=1:1.

P is mid-point of BC.

OP ⊥ BC.

In △ ABP, by pythagoras theorem,

AB2=AP2+BP2

BP2=36−AP2         ....(1)

In △ OBP, we have

OB2=OP2+BP2

52=(5−AP)2+BP2

BP2=25−(5−AP)2      .....(2)

From 1 & 2, we get,

36−AP2=25−(5−AP)2

36=10AP

AP=3.6cm

Substitute in equation 1,

BP2=36−(3.6)2=23.04

BP=4.8cm

Option 3

[tex]P(B) = \frac{1}{8},\ P(B|A) = \frac{1}{4}[/tex]    Dependent

Option 4

[tex]P(B) = \frac{1}{4},\ P(B|A) = \frac{1}{4}[/tex]     Independent

Step-by-step explanation:

Two events A and B are independent if the occurrence of A does not affect the probability of B.

On the other hand The probability of A given B is defined as:

[tex]P (A | B) = \frac{P (A\ and\ B)}{P (B)}[/tex]

When two events are independent then:

[tex]P (A\ and\ B) = P (A) * P (B)[/tex]

So if the two events A and B are independent this means that:

[tex]P (A | B) = \frac{P (A) * P (B)}{P (B)}[/tex]

[tex]P (A | B) = P (A)[/tex]

Which makes sense because if the events are independent then the probability of A not being affected by B.

So to solve this problem identify in what cases

[tex]P (A | B) = P (A)[/tex] or [tex]P (B | A) = P (B)[/tex]

When this happens those events are independent

Option 1.

[tex]P(A) = \frac{1}{8},\ P(A|B) = \frac{1}{3}[/tex]     Dependent

Option 2

[tex]P(A) = \frac{1}{4},\ P(A|B) = \frac{1}{4}[/tex]    Independent

Option 3

[tex]P(B) = \frac{1}{8},\ P(B|A) = \frac{1}{4}[/tex]    Dependent

Answer:

  62 Sunday papers were sold

Step-by-step explanation:

Let x represent the number of Sunday papers sold. Then half that many, or x/2, is the number of Friday papers sold. The total revenue from the sales is the sum of products of quantity and price:

  1.50 · x + 0.75 · (x/2) = 116.25

Multiplying by 2, this becomes ...

  3.00x +0.75x = 232.50

  3.75x = 232.50

Dividing by the coefficient of x gives ...

  232.50/3.75 = x = 62

The number of Sunday newspapers sold is 62.

Answer:

"the addition of a negative constant"

Step-by-step explanation:

Please note the following points of functions regarding transformations:

1. If there is a change in amplitude, the function will be compressed/stretched vertically, keeping other variables constant

2. If there is a phase shift, the function would be horizontally transformed

3. If there is a period change, the function would be horizontally compressed/stretched

4. If there is addition of positive/negative constant, the function would shift vertically upward/downwards, respectively.

We can clearly see from the graph that the new function is a vertical downward shift from the original. Hence, looking at the above points, point #4, addition of a negative constant, is correct.

Answer:

e = 8x + 0.1y

Step-by-step explanation:

If Gustavo makes no sales at all, he still gets $8 per hour worked (x).  We can model this part with this equation:

e = 8x

But then, if he sells something, he makes extra money.. He makes 10% (0.1) of every sale (y).  So the equation becomes:

e = 8x + 0.1y

or you can express it this way:

e = 8x + y/10

which is the same thing just written differently.

Answer:

A = 21.65 cm squared

Step-by-step explanation:

The basic area formula for a triangle is

[tex]A= \frac{1}{2}bh[/tex]

We have our base as 5, so we can find the height using right triangle trig.  Side BC is opposite the given angle, which is the height, and we are given side CD as 5 which is the base.  Using the tangent ratio to find side BC:

[tex]tan(60) = \frac{x}{5}[/tex] which simplifies to

5 tan(60) = x so

x = 8.66

Filling in for the area:

[tex]A= \frac{1}{2}(5)(8.66)[/tex] so

A = 21.65 cm squared

Answer:

(-5 +/- sqrt(65))/2

Step-by-step explanation:

To solve this, we can use the quadratic formula!

So,

x = (-5 +/- sqrt(25+40))/2

x = (-5 +/- sqrt(65))/2

So (-5 +/- sqrt(65))/2  is our answer.

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

We have the function [tex]f(x) = 2x + cosx[/tex]

Note that f(x) is the sum of two continuous functions [tex]h(x) = 2x[/tex] and [tex]g(x) = cosx[/tex]

The domain and range of h(x) are all real numbers

The domain of g(x) is all real numbers. The range of g(x) is [-1, 1]

Then the domain of [tex]f(x) = h(x) + g(x)[/tex] will be the intersection of the domains of the function [tex]h(x) = 2x[/tex] and the function [tex]g(x) = cosx[/tex].

Therefore the domain of f(x) are all real numbers.  x ∈ (-∞, ∞)

The range of f(x) will be equal to the union of the range of g(x) and h(x)

Therefore the range will be all real numbers f(x) ∈ (-∞, ∞)

Answer:

x must be 5

Step-by-step explanation:

Recall that the area formula for a trapezoid is

A = (average of base lengths)(width)

Here we have

                                                                   17 cm + x

      (average of base lengths) = 11 cm = ----------------

                                                                           2

So 2(11 cm) = 17 cm + x, or

      22 cm = 17 cm + x

Then x must be 5.

To find the length of the other base of the trapezoid with a midsegment of 11 cm and one base of 17 cm, use the average property of the midsegment. The calculation reveals the other base is 5 cm in length.

The question is about finding the length of the other base of a trapezoid when the length of the midsegment and one of the bases is known. The midsegment of a trapezoid is parallel and equal to the average of the two bases. Therefore, if the midsegment is 11 cm and one base is 17 cm, the other base can be found by setting up the equation:

Midsegment = (Base1 + Base2) / 2

Substitute the known values:

11 = (17 + Base2) / 2

Multiplying both sides by 2 gives:

22 = 17 + Base2

Subtracting 17 from both sides gives:

Base2 = 22 - 17

Base2 = 5

Thus, the length of the other base of the trapezoid is 5 cm.

Explanation:

1. In order for the idea of "perpendicular distance" to make any sense in this context, the number of sides of the polygon must be even. Then the "diameter" is the diameter of the inscribed circle. As the number of sides increases, the polygon differs less and less from a circle, so the relationship of perimeter and "diameter" becomes closer to the relationship in a circle.

"As the number of sides in a regular polygon increases, the ratio of perimeter to diameter for that polygon approaches pi."

__

2. We know from the first question that ...

circumference/diameter = π

And we know that ...

diameter = 2·radius

Then the following are true:

A. circumference = π · diameter

B. circumference = (2·radius) · π

__

3. The expressions in order evaluate to approximately ...

4.0, 3.45, 3.31, 3.24

Of these, the last is closest to pi (3.14....). The appropriate choice is ...

D. (10·5)/15.4

4. Pi cannot be expressed as a rational number, because pi is irrational. A number of lengthy proofs have been offered to demonstrate this fact. One of them makes use of the fact that the tangent of any rational number is irrational, and the tangent of π/4 is 1. Since 1 is a rational number, π/4 cannot be, so π cannot be expressed as a rational number.
