Answer:

[tex]\displaystyle 33,8 ≈ b \\ 55,1 ≈ a \\ 35° = m∠B[/tex]

Step-by-step explanation:

We will be using the Law of Sines to find edges b and a one at a time, therefore we will use the given variables in the formulas:

Solving for Angles:

[tex]\displaystyle \frac{sin∠C}{c} = \frac{sin∠B}{b} = \frac{sin∠A}{a}[/tex]

**Use [tex]\displaystyle arcsin\:or\:sin^{-1}[/tex]in your solution or you will throw the result off!

Solving for Edges:

[tex]\displaystyle \frac{c}{sin∠C} = \frac{b}{sin∠B} = \frac{a}{sin∠A}[/tex]

__________________________________________________________

[tex]\displaystyle \frac{33}{sin\:34} = \frac{b}{sin\:35} \hookrightarrow \frac{33sin\:35}{sin\:34} = b \hookrightarrow 33,848824408... = b \\ \\ 33,8 ≈ b[/tex]

We will now define edge a:

[tex]\displaystyle \frac{33}{sin\:34} = \frac{a}{sin\:111} \hookrightarrow \frac{33sin\:111}{sin\:34} = a \hookrightarrow 55,093964682... = a \\ \\ 55,1 ≈ a[/tex]

This triangle is now deemed solved.

***The fact that you solved for the [tex]\displaystyle m∠B[/tex]tells me that you understood what to when it comes to the interior angles of triangles, so I did not have to cover that. Good wourk citisen!

I am delighted to assist you at any time. If you have further questions though, comment them and I will do my very best to answer them.

I'm happy to help!

Answer:

Adult tickets are $14

Student tickets are $8

Step-by-step explanation:

let's say that [tex]\tt s=student~ticket\\\\[/tex]

And [tex]\tt a=adult~ticket[/tex]

on the first day we have:

[tex]\tt 3s+a=38[/tex]

On the second day we have

[tex]\tt3s+2a=52[/tex]

now we have a system of 2 equations with 2 unknown

[tex]\tt 3s+a=38[/tex]

[tex]\tt 3s+2a=52[/tex]

we will multiply the first equation with -1

[tex]\tt -3s-a=-38\\\tt ~3s+2a=52[/tex]

we solved the system and

a= $14,  forthe adult ticket

s= $8 for the student ticket

Have an Awesome day!

Using the uniform distribution, it is found that the mathematical expression for the probability density function of battery recharging time for this scenario is given by:

[tex]f(x) = \frac{1}{40}, 70 \leq x \leq 110[/tex]

[tex]f(x) = 0[/tex], elsewhere.

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability density function is:

[tex]f(x) = \frac{1}{b - a}, a \leq x \leq b[/tex]

[tex]f(x) = 0[/tex], elsewhere.

In this problem, the actual recharging time required is uniformly distributed between 70 and 110 minutes, hence a = 70, b = 110, and the density function is:

[tex]f(x) = \frac{1}{40}, 70 \leq x \leq 110[/tex]

[tex]f(x) = 0[/tex], elsewhere.

Considering the desired result of the hypothesis test, we the closest mean time to 1.5 hours, hence the correct option is:

C. 1.6 hrs

The closer the mean is to the sample mean, the less likely we are to reject the null hypothesis.

In this problem, the sample mean is of 1.5 hours, hence, the closest value, considering the absolute value of the difference, is of 1.6 hours, hence option C is correct.

Answer: 3%

Step-by-step explanation:

first roll 1 out of 6 chance or 16%

second roll is also 1 out of 6 chance or 16%

Mulitple .16 by .16 to get .0256 rounded to whole percentage 3%

A triangle has three sides, the first, second, and the add up to 24, since that's the perimeter

The second side = the first (let's call it L) + 2

The third is two more then the second, so L + 2 + 2

first side = L

second = L + 2

third = L + 2 + 2

add all three together, L + L + 2 + L + 2 + 2 = 24

combine the L's and 2's

3L + 6 = 24

subtract 6 from both sides

3L = 18

divide by 3

L=6

so the first side is 6, the second is 8, the third is 10

Answer:

B

Step-by-step explanation:

x² - 6x = 0

Answer:

(1, 5)

Step-by-step explanation:

The solution to the system of equations is the point of intersection of the two lines.  From inspection of the graph, the point of intersection is at (1, 5).

Proof

The solution to a system of equations is the point at which the two lines meet.  

⇒ g(x) = f(x)

⇒ 3x + 2 = |x - 4| + 2

⇒ 3x = |x - 4|

⇒ 3x = x - 4   and   3x = -(x - 4)

⇒ 3x = x - 4

⇒ 2x = -4

⇒ x = -2

Inputting x = -2 into the 2 equations:

⇒ g(-2) = 3 · -2 + 2 = -4

⇒ f(-2) = |-2 - 4| + 2 = 8

Therefore, as the y-values are different, x = -2 is NOT a solution

⇒ 3x = -(x - 4)

⇒ 3x = 4 - x

⇒ 4x = 4

⇒ x = 1

Inputting x = 1 into the 2 equations:

⇒ g(1) = 3 · 1 + 2 = 5

⇒ f(1) = |1 - 4| + 2 = 5

Therefore, as the y-values are the same, x = 1  IS a solution

and the solution is (1, 5)

Answer:

5/4

Step-by-step explanation:

B = kC/D³

Given B = 5, C = 2, D = 1

so 5 = k(2)/1³ = 2k, k = 5/2 = 2.5

B = 2.5C/D³

when C = 4, D = 2

B = 2.5 * 4/2³ = 10/8 = 5/4

X = 2 cm

Y = 1. cm

Answer:

the price of each adult ticket is $43

Step-by-step explanation:

Let's say the price for 1 adult ticket is x and the price for 1 child ticket is y

3y = 18.5 and 3y + 2x = 104.50

2x + 18.5 = 104.50

2x = 104.5 - 18.50

2x = 86

x = [tex]\frac{86}{2}[/tex]

x = 43

So the price for 1 adult ticket is $43

Answer:

Let's say the price for 1 adult ticket is x and price for 1 child ticket is y

3y = 18.5 and 3y + 2x = 104.5

<=> 2x + 18.5 = 104.5

<=> 2x = 104.5 - 18.5

<=> 2x = 86

<=> x = 86 / 2

<=> x = 43

So the price for 1 adult ticket is $43

to find out what the price is after an increase of 3.5%, set it as 103.5% of the original price and then we convert the percent to a decimal (divide by 100)

so:

$3.25 x 103.5% =

3.25 x 1.035 = $3.36

Answer:

$3.36

Step-by-step explanation:

0.11375(3.5% of $3.25) + 3.25 = 3.36375

Answer:

b(n) = 15 - 7(n - 1)

Step-by-step explanation:

Answer:

aₙ = 11 - 9(n - 1)

Step-by-step explanation:

2 - 11 = (-7) - 2 = -9

So it is an arithmetic sequence

a₁ = 11

a₂ = 2 = 11 + (-9) = 11 + (2 - 1)*(-9)

a₃ = -7 = 2 + (-9) = 11 + (-9) + (-9) = 11 + (3 - 1)*(-9)

.....

aₙ = 11 + (n - 1) * (-9)

or

aₙ = 11 - 9(n - 1)

[tex](s^2 Y(s) - sy(0) - y'(0)) - (s Y(s) - y(0)) = \dfrac1{s+3}[/tex]

[tex](s^2 - s) Y(s) = \dfrac1{s+3}[/tex]

[tex]Y(s) = \dfrac1{(s^2 - s)(s+3)} = \dfrac1{s(s-1)(s+3)}[/tex]

Partial fractions:

[tex]Y(s) = \dfrac as + \dfrac b{s-1} + \dfrac c{s+3}[/tex]

[tex]\implies 1 = a(s-1)(s+3) + b s(s+3) + c s(s - 1)[/tex]

[tex]\implies 1 = -3 a + (2 a + 3 b - c) s + (a + b + c) s^2[/tex]

[tex]\implies \begin{cases}-3a=1 \\ 2a+3b-c=0 \\ a+b+c=0\end{cases} \implies a=-\dfrac13, b=\dfrac14, c=\dfrac1{12}[/tex]

[tex]\implies Y(s) = -\dfrac13 \times \dfrac1s + \dfrac14 \times \dfrac1{s-1} + \dfrac1{12} \times \dfrac1{s+3}[/tex]
