Answer:

1. H ≈ 49.1°

2. F ≈ 38.0°

3. R ≈ 17.0°

Step-by-step explanation:

1.

We need to find angle H, which is the third angle. We are given two sides and an angle, so we can use the Law of Sines to solve.

The Law of Sines states that for a triangle with side lengths a, b, and c and angles A, B, and C:

\frac{a}{sinA} =\frac{b}{sinB}  =\frac{c}{sinC}

Here, we can say that a = 22, b = 27, and B = 68. We want to find "A", which is the same angle as H:

\frac{a}{sinA} =\frac{b}{sinB}

\frac{22}{sinH} =\frac{27}{sin(68)}

Solve for H:

H ≈ 49.1°

2.

Use the Law of Sines again (use the same method as above):

\frac{17}{sin(108)} =\frac{11}{sin(F)}

Solve for F:

F ≈ 38.0°

3.

Use the Law of Sines again (use the same method as before):

\frac{9}{sin(26)} =\frac{6}{sin(R)}

Solve for R:

R ≈ 17.0°

A divide by sin A = b divide by sin B
1. 27 divide by sin 68=22 divide by sin x
Sin x=sin 68 times 22 divide by 27
Sinx=0.65696
X=71.7 degrees

The function g(x) is defined as g(x) = −2x^2 + 3x.The value of g(−3) is
Tresset [83]

Answer:

g(-3) = -27

Step-by-step explanation:

g(x) = -2x² + 3x ---> g(-3)

g(-3) = -2<u>(-3)²</u> + 3(-3)

g(-3) = <u>-2(9)</u> + <u>3(-3)</u>

g(-3) = <u>-18 - 9</u>

g(-3) = -27

Hope this helps, thank you :) !!

PLZ I REALLY NEED HELP Find the values of x and y in parallelogram PQRS
brilliants [131]

Answer:

x = 5 and y = 7

Step-by-step explanation:

Given that,

PT = x+2, TR=y, QT=2x, TS=y+3

We need to find the value of x and y.

The diagonal of a parallelogram bisect each other. It means,

PT = TR and QT = TS

ATQ,

y = x+2 ...(1)

and

y+3 = 2x ....(2)

Subtracting equation (1) and (2).

y-(y+3) = x+2-2x

y-y-3 = 2-x

-3 = 2-x

x = 2+3

x = 5

Put the value of x in equation (1).

y = 5 + 2

y = 7

Hence, the values of x and y are x = 5 and y = 7.

This exercise uses, the population growth model
timofeeve [1]

P is equal to 8700% for population x time in hours.

<h3>What is population growth model?</h3>

P is equal to 8700% for population x time in hours. 2Ae%5E%28kx%29

K's model must be solved. ln%28p%29=ln%288700%29%

2Bkx%2Aln%28e%

29\skx%

2A1=ln%28p%29-ln%288700%

29\sk=%281%

2Fx%29%

28ln%28p%29-ln%288700%29%29

Replace the point (1,10000).

k=%281%

2F1%29%

28ln%2810000%

29-ln%288700%

29%

29\sk=ln%2810000%

29-ln%288700%

29 k=0.13926, which you might only desire to three or maybe even two significant figures.

You may just enter 10000% if you want p after two hours.

And it SHOULD be the same as 8700% (2810000%2F8700%).

Just give it a shot and see, 2Ae%5E%280.139%2A2%29. More particular, the model is highlighted by p=8700%. 2Ae%5E%280.139% 2Ax%29% 29.

Determine how long to double x.

Take the logs on both sides, then find x.

To put it more simply, start with this form: 2=1%2Ae%5E%280.13926%2Ax%29

Mathew rolls a number cube labeled with the numbers 1−6. He then flips a fair coin. What is the probability that he rolls a 4 an
KATRIN_1 [288]

Answer:

0.083

Step-by-step explanation:

Numbers of Cube = 6

Faces on coins = 2

Therefore, The total outcomes = 6 \times 2 = 12

Now the favourable outcome that he rolls a 4 & flips a head = 1

The probability that he rolls a 4 & flips a head = 1

\frac{Favourable \: Outcome}{Total \: Outcome}

=> The probability that he rolls a 4 & flips a head = \frac{1}{2}  = 0.83333/ approx. 0.83

Therefore, The probability that he rolls a 4 & flips a head = 0.083
