Answer:

QR ≈ 16.2 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan62° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{QR}{RP}[/tex] = [tex]\frac{QR}{8.6}[/tex] ( multiply both sides by 8.6 )

8.6 × tan62° = QR , then

QR ≈ 16.2 ft ( to the nearest tenth )

Answer:

B) -8/9

Step-by-step explanation:

multiply - 3/6 by three to have the same denominator as -7/18 so that they can add up

=> -9/18 + (-7/18) = -16/18 = -8/9

Step-by-step explanation:

The Tet Offensive considered a turning point in the Vietnam War because:

Troops from the United States and South Vietnam targeted North Vietnamese and Viet Cong hideouts in Cambodia and Laos.

Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.

As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.

Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.

Answer:

12% of 2500 is 300

Step-by-step explanation:

[tex]\frac{12}{100} = \frac{300}{y}[/tex]

12 × y = 100 × 300

12y = 30000

12y ÷ 12 = 30000 ÷ 12

y = 2500

Answer:

Ann us correct. It's a quadratic function.

Step-by-step explanation:

Given equation is,

y = 3x(x - 7)

By converting this equation into the standard quadratic equation,

y = 3x² - 21x

Highest exponent of the polynomial equation is 2 (Exponent of highest degree variable x²). This decides that the given function is a quadratic function.

Therefore, Ann is correct. It's a quadratic function.

Answer:

Rui will reach his lowest altitude after 20seconds of diving

Step-by-step explanation:

Given the function that models the altitude of Rui at any time x expressed as:

d(x) = 1/2 x² - 10x

The height of rui at his lowest altitude will be zero. Substitute d(x) = 0 into the expression and get x

d(x) = 1/2 x² - 10x

0 = 1/2 x² - 10x

-1/2x² = 10x

1/2 x = 10

Multiply both sides by 2

x/2 × 2 = 10×2

x×1 =20

x = 20

Hence Rui will reach his lowest altitude after 20seconds of diving

Answer: well i have put things like leather and it shrunk while it was out in the sun

Step-by-step explanation:

We want to study how the Sun affects things on Earth, I will give you two examples.

First, we know that the Sun radiates electromagnetic energy.

So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.

The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).

Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.

So these are just two different examples of how the Sun affects things on Earth.

49 total dogs.

36 more small dogs.

13 big dogs.

lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.

the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.

Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.

F** k today's hw and their wording

Answer:

6.5 Large Dogs

42.5 Small Dogs

Step-by-step explanation:

You simply do not have enough love for dogs to solve the question.

Luckily I have an extremely high affection for dogs so I can help.

S = amount of small dogs

L = amount of large dogs

S + L = 49

S = 36 + L

plug the second equation into the correct variable of the first equation so:

(36+L) + L = 49

36 +2L = 49

2L = 49-36

L = 6.5      *this doesn't make sense*

S = 42.5    *this also doesn't make sense*

Answer:

-3,8

Step-by-step explanation:

The number 2 or 6 would be rolled 200 times.

Important information:

Number cube has six numbers 1, 2, 3, 4, 5, 6. So, the probability of getting either 2 or a 6 is:

[tex]P(2\cup 6)=\dfrac{2}{6}[/tex]

[tex]P(2\cup 6)=\dfrac{1}{3}[/tex]

The expected value of getting a 2 or a 6 would be rolled is:

[tex]E(2\cup 6)=600\times P[/tex]

[tex]E(2\cup 6)=600\times \dfrac{1}{3}[/tex]

[tex]E(2\cup 6)=200[/tex]

Therefore, the number 2 or 6 would be rolled 200 times.

Step-by-step explanation:

360/24 =15whichis number of sides

180(15-2)=2340

Answer:

Exterior Angle of 24º means Interior Angle of 156º

Interior Angle = 180 -Exterior Angle

Number of sides = 360 / (180 - ONE Interior Angle)

Number of sides = 360 / (180 - 156º)

Number of sides = 360 / 24

Number of Sides = 15

Answer: -4

Step-by-step explanation:

The common ratio of the geometric sequence  [tex]19, -76, \ 304, \ ...[/tex] is [tex](-4)[/tex] .

Geometric sequence also known as a geometric progression, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. i.e.  [tex]r=\frac{a_{k+1} }{a_{k} }[/tex]

Common ratio the number which is multiplied (or divided) at every stage of a geometric sequence.

We have,

Geometric sequence  [tex]19, -76, \ 304, \ ...[/tex]

Here,

[tex]a_{1} =19, \ a_{2} =(-76), \ a_{3} =304[/tex]

So,

[tex]r=\frac{-76}{19}[/tex]

[tex]r=(-4)[/tex]

So,

Common ratio of the given geometric sequence  is [tex](-4)[/tex] .

Hence, we can say that the common ratio of the geometric sequence  [tex]19, -76, \ 304, \ ...[/tex] is [tex](-4)[/tex] .

There are a few ways you can go at this. Perhaps the simplest is to recognize that 81 is a power of 3.

  log₃(81) = log₃(3⁴)

  log₃(81) = 4
