PLEASE HELP ASAP IM TRYING TO GO TO RECESS LOL

Answer:

The lighthouse is 424 feet away.

Step-by-step explanation:

There is no other way to do this but to use one of the 6 trigonometry functions.

Drawing

Draw a dotted horizontal line.

judge an angle that could be 23o. Let it slant downward from the left side of the dotted line.

Draw another horizontal line that represents sea level.

Join the left side of the dotted line to the last line you drew. The angle on your right is also 23o.

Function

You have 6 trig functions to choose from. You have the lighthouse height (180 feet) the angle on your right, and the length on the horizontal representing the distance from the lighthouse base to the boat.

You have an angle

You have an opposite side

You have a horizontal line (the adjacent side)

You want to use the tangent function.

Tan(23) = opposite / ad

Tan(23) = 180 / adjacent     Multiply both sides by the adjacent

adjacent*Tan(23)= 180        Divide by Tan(23)

adjacent = 180/Tan(23)

adjacent = 180 / 0.42447

adjacent = 424 feet.

Answer:

Vertical asymptotes: x=-9 and x=3

Slant asymptote: y=5x-1

Step-by-step explanation:

Given

f(x)=(5x^3+29x^2-140x+21)/(x^2+6x-27)

For vertical asymptote, the denominator is put equal to zero,so

x^2+6x-27=0

Factorizing

x^2+9x-3x-27=0

x(x+9)-3(x+9)=0

(x+9)(x-3)=0

So,

x=-9 ;x=3

As the degree of the numerator is greater than the denominator the function will not have horizontal asymptote but it will have a slant asymptote which will be calculated by long division.

After dividing 5x^3+29x^2-140x+21  by x^2+6x-27  we get

Quotient: 5x-1

Remainder: x-6

We only need the quotient for the slant asymptote,

So the slant asymptote is y = 5x -1  ..

Answer:

Vertical asymptotes: x=-9 and x=3

Slant asymptote: y=5x-1

Step-by-step explanation:

Im gonna have to say its c

Answer: z = -3 , y = 2 , x = 2

The solution to the system of equations is: x - y + 9z = -27 , 2x - 4y - z = -1 , 3x + 6y - 3z = 27 is

x = 2

y = 2

z = -3

Given the system of equations:

1. x - y + 9z = -27

2. 2x - 4y - z = -1

3. 3x + 6y - 3z = 27

We'll use the method of elimination to solve this system.

Step 1: Eliminate y from equations (1) and (2):

Adding equations (1) and (2):

(x - y + 9z) + (2x - 4y - z) = -27 + (-1)

x + 2x - y - 4y + 9z - z = -27 - 1

3x - 5y + 8z = -28

Step 2: Eliminate y from equations (2) and (3):

Multiplying equation (2) by (3) and equation (3) by (2):

6x - 12y - 3z = -3  (from equation 2)

6x + 12y - 6z = 54 (from equation 3, after multiplying by 2)

Adding these two equations:

(6x - 12y - 3z) + (6x + 12y - 6z) = -3 + 54

6x + 6x - 12y + 12y - 3z - 6z = 51

12x - 9z = 51

Now, we have two equations:

1. 3x - 5y + 8z = -28

2. 12x - 9z = 51

From equation (2), let's solve for (x):

12x - 9z = 51

12x = 51 + 9z

x = (51 + 9z) ÷ 12

Now, we'll substitute this expression for (x) into equation (1) to solve for (z):

3x - 5y + 8z = -28

[tex]\[ 3\left(\frac{51 + 9z}{12}\right) - 5y + 8z = -28 \][/tex]

[tex]\[ \frac{153 + 27z}{12} - 5y + 8z = -28 \][/tex]

Next, we'll isolate (z):

153 + 27z - 60y + 96z = -336

249z - 60y = -489

Now, let's solve for (z):

249z = -489 + 60y

z = (-489 + 60y) ÷ 249

Now, we'll substitute the expression for (z) back into equation (2) to solve for (y):

[tex]\[ 12x - 9\left(\frac{-489 + 60y}{249}\right) = 51 \][/tex]

[tex]\[ 12x - \frac{-489 + 60y}{27} = 51 \][/tex]

[tex]\[ 12x = 51 + \frac{-489 + 60y}{27} \][/tex]

[tex]\[ x = \frac{51 + \frac{-489 + 60y}{27}}{12} \][/tex]

[tex]\[ x = \frac{51\times27 + -489 + 60y}{12\times27} \][/tex]

[tex]\[ x = \frac{1377 - 489 + 60y}{324} \][/tex]

[tex]\[ x = \frac{888 + 60y}{324} \][/tex]

[tex]\[ x = \frac{148 + 10y}{54} \][/tex]

Now, we'll substitute the expressions for (x) and (z) into equation (1) to solve for (y):

x - y + 9z = -27

[tex]\[ \frac{148 + 10y}{54} - y + 9\left(\frac{-489 + 60y}{249}\right) = -27 \][/tex]

The least common multiple of (54) and (249) is (54 × 249).

⇒ (148 + 10y) × 249 - 54 × 249 × y + 9 × 54 × (-489 + 60y)  = -27 × 54 × 249

⇒ 36752 + 2490y - 133146y - 233640 + 29160y = -1458 × 249

⇒  2490y - 133146y + 29160y + 36752 - 233640 = -1458 × 249

⇒ -106496y - 197888 = -362682

⇒ -106496y = -164794

⇒ y = (-164794) ÷ (-106496)

y ≈ 1.547

y ≈ 2

Now that we have found (y = 2), we can substitute this value back into the expressions for (x) and (z) to find their values.

For (x):

[tex]\[ x = \frac{148 + 10(2)}{54} = \frac{168}{54} = 2 \][/tex]

For (z):

[tex]\[ z = \frac{-489 + 60(2)}{249} = \frac{-369}{249} = -\frac{3}{1} = -3 \][/tex]

So, the solution to the system of equations is:

x = 2

y = 2

z = -3

First, do you know what a CD is? ;-)

Since you will pick 3 CDs out of 8, and the order of the CDs don't import (1,2,4 is the same as 2,1,4 and 4,2,1 for example),we'll calculate the Combinations (and not the permutations). The formula for Combinations is:

[tex]C(n,r) = \frac{n!}{(r!(n-r)!)}[/tex]

Where n is the number of elements (8 in our case) an n is the sample (3 in our case).

[tex]C(8,3) = \frac{8!}{(3!(8-3)!)} = \frac{40320}{6 * 120} = 56[/tex]

So, there are 56 random groups of 3 you can pick from your potential 8 CDs.

[tex]\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}[/tex]

to get: [tex]\frac{27}{12} - \frac{8}{12}[/tex].

now the denominators is the same on both sides, just subtract the numerator.

Answer:

B

Step-by-step explanation:

Using the law of sines, we can make a proportion.

But first, we'll need to solve for the unknown angle.

We add up the two known angles and subtract that by 180.

90 + 41 = 131

180 - 131 = 49

So the unknown angles is 49.

Then, we can use the law of sines.

Make the equation.

sin(90)/55 = sin(49)/x

Simplify this using a calculator and you get around 41.51 or option B.

The correct option is B. [tex]41.51[/tex] The value of [tex]\( x \)[/tex] to the nearest hundredth

To find the value of [tex]\( x \)[/tex] to the nearest hundredth, we need to use the trigonometric functions for the right triangle given.

We are given:

The hypotenuse [tex](\( 55 \))[/tex]

An angle [tex](\( 41^\circ \))[/tex]

We need to find the adjacent side[tex](\( x \))[/tex]

We can use the cosine function, which is defined as:

[tex]\[\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}}\][/tex]

Substituting the given values:

[tex]\[\cos(41^\circ) = \frac{x}{55}\][/tex]

Solving for \( x \)

[tex]\[x = 55 \times \cos(41^\circ)\][/tex]

Using a calculator to find \(\cos(41^\circ)\)

[tex]\[\cos(41^\circ) = 0.7547\][/tex]

In order for these lengths to form a right triangle they need to satisfy the equation:

So plugging in:

That 7 in the 4th position of the given decimal is greater than 5 and thus indicates that we must round that 4 up:

The number 25.0347 rounded to 3 decimal places is 25.035.

The question is asking to round the number 25.0347 to 3 decimal places. As it is, the number 25.0347 already has 4 decimal places. Rounding it to 3 decimal places means you should retain up to the thousands place (3 digits after the decimal point) and adjust the last digit based on the digit that comes after it. If the 4th digit after the decimal point is 5 or more, you round up. If not, you just drop it.

In the number 25.0347, the fourth digit after the decimal point is 7, which is greater than 5. Therefore, we round up the third digit (4) by 1. So, the number 25.0347 rounded to 3 decimal places is 25.035.
