A tent guy line supports one of the upright tent poles. It runs from the top of the pole to a peg in the ground two and a half metres away from the base of the pole. If the guy line is 359cm long, how tall is the upright tent pole? Give your answer in centimetres correct to the nearest centimetre.

Answers

Answer 1

Answer:

258 cm

Step-by-step explanation:

Given:

Distance from the base of the pole to the base of a tent guy line is [tex]2\frac{1}{2}[/tex]

Length of a tent guy line is 359 cm

To find: Height of the upright tent pole

Solution:

Let AB denotes the pole and AC denotes a tent guy line.

According to Pythagoras theorem, in a right angled triangle, square of hypotenuse is equal to sum of squares of other two sides.

[tex]AC^2=AB^2+BC^2[/tex]

[tex]AC=359 cm\\AB=x\\BC=2\frac{1}{2}\,m=\frac{5}{2}\,m=\frac{5}{2}\times 100=250\,cm[/tex]

Therefore,

[tex](359)^2=x^2+(250)^2\\128881=x^2+62500\\128881-62500=x^2\\66381=x^2\\x=257.6\,cm\approx 258\,cm[/tex]

Answers

Answer:

Step-by-step explanation:

The number of dollars Left always needs to be even if you want to buy albums last because we can never have half an album. So if you download 4 songs that leaves you left with $8.

0.25x4

=1

Now with the rest of the money you can download 4 albums.

4 individual songs, 4 albums.

0.25x4+4x2

=1+8

= $9

12 individual songs, 3 albums

0.25x12+2x3

= 3+6

=$9

20 individual song, 2 albums

0.25x20+ 2x2

The fifth graders to plant a butterfly garden. Clover grows in ½ of the garden, daisies in ¼ of the garden, coneflowers in ⅛ of the garden, and milkweed in ⅛ of the garden.

Answers

Answer:

Fraction of the garden used =  [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

The fifth graders to plant a butterfly garden.

We are given that

Clover grows in ½ of the garden

Daisies grow in ¼ of the garden

Coneflowers grow in ⅛ of the garden

milkweed grows in ⅛ of the garden

The fifth graders notice that the butterflies land on the clover and milkweed.

We are asked to find out the fraction of the garden that the butterflies used.

Fraction of the garden used = clover + milkweed

Fraction of the garden used =  [tex]\frac{1}{2} + \frac{1}{8}[/tex]

The LCM of 2 and 8 is 8

Fraction of the garden used =  [tex]\frac{4 +1}{8}[/tex]

Fraction of the garden used =  [tex]\frac{5}{8}[/tex]

Therefore, the butterflies used [tex]\frac{5}{8}[/tex] fraction of the garden.

3. Answer (D). Although this triangle is right, we are not given enough information to uniquely determine its sides and angles - here, we need either one more side or one more angle.

4. Answer (D). Don't get tripped up by answer choice (C) - this is just a rearrangement of the statement of the law of cosines. In choice (D), the signs of [tex]a^2[/tex] and [tex]2ab\cos C[/tex] are reversed.

5. Answer (B).

When a volcano erupts, the height of the peak is reduced and the upper portion is removed. The height of a volcano after it erupted was 8,219.5 feet. This was 85% of the original height. What was the original height?

Answers

Answer:

9,670

Step-by-step explanation:

8,219.5 ÷ 85% (0.85) = 9,670

The height of the volcano is reduced after the eruption, then the original height of the volcano is 9670 feet.

What is the Percentage?

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information in the question,

Height of the volcano after eruption = 8,219.5 feet

Let the original height of the volcano is x.

85% of x = 8219.5

x = (8219.5 × 100)/85

x = 9670 feet.

Answer:

80%

Step-by-step explanation:

We need to find the percent of change from 3,545 pt to 709 pt.

Original value is 3,545

Changed value is 709

Percent change is given by :

[tex]\%=\dfrac{\text{difference in values}}{\text{original value}}\times 100\\\\\%=\dfrac{3545-709}{3545}\times 100\\\\\%=80\%[/tex]

Answers

Answer:

S(t) = a.sin (b.t) + d

a = -1.5, b = (2π/365), d = 3.47

S(t) = -1.5 sin (2πt/365) + 3.47

Step-by-step explanation:

Complete Question is presented in the attached image to this solution.

- Dingane has been observing a certain stock for the last few years and he sees that it can be modeled as a function S(t) of time t (in days) using a sinusoidal expression of the form

S(t) = a.sin(b.t) + d.

On day t = 0, the stock is at its average value of $3.47 per share, but 91.25 days later, its value is down to its minimum of $1.97.

Find S(t). t should be in radians.

S(t) =

Solution

S(t) = a.sin(b.t) + d.

At t = 0, S(t) = $3.47

S(0) = a.sin(b×0) + d = a.sin 0 + d = 3.47

Sin 0 = 0,

S(t=0) = d = 3.47.

At t = 91.25 days, S(t) = $1.97

But, it is given that T has to be in radians, for t to be in radians, the constant b has to convert t in days to radians.

Hence, b = (2π/365)

S(91.25) = 1.97 = a.sin(b×91.25) + d

d = 3.47 from the first expression

S(t = 91.25) = a.sin (91.25b) + 3.47 = 1.97

1.97 = a.sin (2π×91.25/365) + 3.47

1.97 = a sin (0.5π) + 3.47

Sin 0.5π = 1

1.97 = a + 3.47

a = -1.5

Hence,

S(t) = a.sin (b.t) + d

a = -1.5, b = (2π/365), d = 3.47

S(t) = -1.5 sin (2πt/365) + 3.47

2.5 inches, 2.5 inches, and 2.5 inches
6.7 inches, 1.1 inches, and 7.9 inches

Answers

Answer:

AD and BE is perpendicular => angle BED = 90 deg.

Otherwise angle CED = arc CD = 30 deg

=> angle BEC = angle BED - angle CED = 90 - 30 = 60 deg

Suppose a, b and c are 3 sides of a triangle in which a < b < c.

As property of length of sides a, b, and c of a triangle:

c - b < a < c + b

b - a < c < b + a

c - a < b < c + a

We have the function [tex]g(x)=-3x^2+18x+2[/tex]

We can plug in our know values into the formula to get

Then we can plug in our x-value to find the y-value of the vertex

[tex]g(3)=-3(3)^2+18(3)+2\\\\g(3)=-3(9)+54+2\\\\g(3)=-27+54+2\\\\g(3)=29[/tex]

What is Exponential Function?

The formula for an exponential function is f (x) = aˣ, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.

Given the term (b³)²

we know a² = a*a

so (b³)² = b³*b³

and a³ = a*a*a

(b³)² = b³*b³ = b*b*b*b*b*b

so (b³)² without exponent is b*b*b*b*b*b

and we know (aⁿ)ˣ = aⁿˣ

(b³)² = b⁶

Hence term without exponent is  b*b*b*b*b*b and compared power is b⁶.
