The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

Mathematics

GarryVolchara [31]3 years ago
3 0

Answer:

85.1 ft

Step-by-step explanation:

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

We solve using the Trigonometric function of Cosine

cos y = adjacent/hypotenuse

y = angle = 20°

Adjacent = 80 ft

Hypotenuse = ?

cos 20 = 80/Hypotenuse

Hypotenuse = 80/cos 20

x = 85.134221798 ft

Approximately = 85.1 ft

Length of the slide = 85.1 ft

Write the equation of the line passing through (2,-3) and parallel to y=4x-9.
maks197457 [2]

Answer:

y = 4x - 11 .

Step-by-step explanation:

The line y = 4x - 9 has a slope of 4 so our line will also contain 4x.

Using the point-slope form of the equation of a line:

y - y1 = m(x - x1)  ,   we have m = 4 and (x1, y1) = (2, -3):

y - -3 = 4(x - 2)

y + 3 = 4x - 8

y = 4x - 11  (answer).

Fiona is pricing two bicycles one is 175 with 10% and the other is 225 with 35% off which bicycle can she afford if she has 150
Gekata [30.6K]
If the one for $175 is 10% off, that means Fiana pays 90% of the price

175 * 0.9 = $157.50

It is too expensive because 157.50 is more than the 150 Fiana has.

The second bike for $225 is 35% off which means Fiana pays 65% of the price.

225 * 0.65 = $146.25

She CAN afford the bike for $225

Describe the sequence of transformations from quadrilateral ABCD to A'B'C'D A: -8,8 B: 8,-2 C: 4,-8 D: 4,-2 A': 2,-10 B': 8,-10
butalik [34]

Answers:

See below  

Step-by-step explanation:

First transformation

Reflection about the line y = 6.

This inter-converted Points A and C and Points B and D.

The coordinate transformations were (Fig. 1):

A: (-8, 8) ⟶ (-8, 4)

B: (-2, 8) ⟶ (-2, 4)

C: (-8, 4) ⟶ (-8, 8)

D: (-2, 4) ⟶ (-2, 8)

Second transformation

Translation 10 units to the right and 14 units down.

The coordinate transformations were (Fig. 2):

A: (-8, 4)  ⟶ (2, -10)

B: (-2, 4)  ⟶ (8, -10)

C: (-8, 8)  ⟶ (2,   -6)

D: (-2, 8) ⟶ (8,    -6)

The transformations were:

  1. Reflection about the line y = 6
  2. Translation 10 units to the right and 14 units down

Do the phrases 6 less a number y and 6 less than a number y mean the same thing? Explain. A. No, they do not both mean the same
Yuri [45]

Answer:

B. Yes, they both mean the same thing. They can also both be represented by the expression y - 6.

Step-by-step explanation:

Given

Phrase 1: 6 less a number y

Phrase 2: 6 less than a number y

<em>Mathematically,</em>

Phrase 1 can be represented as follows;

y - 6

<em>Mathematically,</em>

Phrase 2 can be represented as follows;

y - 6

<em>Since the representation  of both phrases are the same, then option B answers the question.</em>
