The airplane was 32,000 feet above sea level. It landed in a valley 100 feet below sea level. Write an integer to express the change in the altitude

ANSWER

[tex]\tan(\pi + \theta)= \frac{5}{12} [/tex]

EXPLANATION

We first obtain

[tex] \cos( \theta) [/tex]

using the Pythagorean Identity.

[tex]\cos ^{2} ( \theta) + \sin ^{2} ( \theta) = 1[/tex]

[tex] \implies \: \cos ^{2} ( \theta) + ( - \frac{5}{13} )^{2} = 1[/tex]

[tex]\implies \: \cos ^{2} ( \theta) + \frac{25}{169}= 1[/tex]

[tex]\implies \: \cos ^{2} ( \theta) = 1 - \frac{25}{169}[/tex]

[tex]\implies \: \cos ^{2} ( \theta) = \frac{144}{169}[/tex]

[tex]\implies \: \cos ( \theta) = \pm \: \sqrt{\frac{144}{169} } [/tex]

[tex]\implies \: \cos ( \theta) = \pm \: \frac{12}{13} [/tex]

In the third quadrant, the cosine ratio is negative.

[tex]\implies \: \cos ( \theta) = - \: \frac{12}{13} [/tex]

The tangent function has a period of π and [tex]\pi + \theta[/tex] is in the third quadrant.

This implies that:

[tex] \tan(\pi + \theta)= \tan( \theta) [/tex]

[tex]\tan(\pi + \theta)= \frac{ \sin( \theta) }{ \cos( \theta) } [/tex]

[tex]\tan(\pi + \theta)= \frac{ - \frac{ 5}{13} }{ - \frac{12}{13} } [/tex]

This gives us:

[tex]\tan(\pi + \theta)= \frac{5}{12} [/tex]

Hey there! Thanks for asking your question here on Brainly.

Let's split this question up into two parts: large and cold drink. Now that we have our two parts, we need to figure out which would be the numerator and which would be the denominator. Looking at the question, the size large would be the numerator because that is the part out of the whole we are finding. The whole would be cold drink because that is given, meaning that we are looking for the larges out of the entire cold drink section.

Now, we'll find the total amount of customers that ordered cold drinks for the whole part of our fraction. That is 25 customers. Next, we set the numerator of our fraction to the amount of customers that ordered large, cold drinks. Therefore, our fraction would be 5/25. The fraction in decimal form is 0.2, and in percent form is 20%.

Therefore, the probability that a customer ordered a large given that he or she ordered a cold drink is 20%.

Hope this helps! If there is anything else that I can help you with, please let me know! :)

Answer:

We only need one simple theorem for this.

Theorem 7 - The Exterior Angle Theorem: An exterior angle of a triangle is equal to the sum of the two remote interior angles.

So in this case, the measurement of the exterior angle is (45x)°, and the interior angles are (25x)° and (57 + x)°.

=> Therefore, we have:

25x + (57 + x) = 45x

25x + x - 45x  = - 57

-19x                 = -57

x                      = -57/(-19) = 3

So x = 3

Outside angle = addition of the two inner angles.

45x = 25x + 57 + x

45x = 26x + 57

45x - 26x = 57

19x = 57

x = 57/19

x = 3

Did you follow the logic?

Final answer:

Two teams working together will take approximately 133.33 hours or about 5.56 days to clean the city streets. This is less than the one week (7 days) available before filming begins, so the streets will be clean in time.

Explanation:

To calculate how long it will take for two teams working together to clean the city streets, we use the concept of combined work rates.

The first team requires 200 hours to clean the streets, while the second team requires 400 hours.

When working together, we can add their rates of work, which means the first team cleans 1/200 of the city per hour, and the second team cleans 1/400 of the city per hour.

The combined rate of work will be:
1/200 (team A's rate) + 1/400 (team B's rate)
= 2/400 + 1/400
= 3/400

So, together they clean 3/400 of the city per hour. To find out how many total hours it will take to clean the entire city, we take the reciprocal of their combined rate
1 / (3/400)
= 400/3
≈ 133.33 hours

Since there are 24 hours in a day, we divide the total hours by 24 to find out how many days it will take:
133.33 hours / 24 hours/day
≈ 5.56 days
Given that the crew will arrive in one week, which is 7 days, this is within the time frame required before filming begins. The teams have enough time to clean the streets before the cameras start rolling.

Answer:

x = - 10

Step-by-step explanation:

Answer:

x > 1/6

Step-by-step explanation:

Perform the indicated multiplication.  Then:

-16x + 8 < 2x + 5

Combining the x terms, we get:

8 < 18x + 5.

Simplifying further, we get:

3 < 18x, so that   3/18 < x, or x > 1/6

Answer:

  120 miles

Step-by-step explanation:

We have to "interpret" the problem statement, because its literal meaning is that it takes Adam a negative amount of time to drive the distance when driving faster. 2.5 times 4 hours is 10 hours. 10 hours less than 4 hours is -6 hours, meaning that driving faster gets Adam to the park 6 hours before he started driving.

So, we assume the intent of the problem is that driving faster multiplies Adam's travel time by a factor of 1/2.5, 2/5 of what it was at the lower speed. Since travel time is inversely proportional to speed, Adam's speed is effectively multiplied by 2.5 by driving faster. We can use the relation ...

  speed = distance/time

to relate the speeds (in mph) and times (in hours) given in the problem. For some distance d, we have ...

  45 + d/4 = 2.5(d/4) . . . . . adding 45 mph to his speed multiplies it by 2.5

Multiplying by 4 gives ...

  180 + d = 2.5d

  180 = 1.5d . . . . . . . . subtract d

  180/1.5 = d = 120 . . . divide by 1.5

Adam covers a distance of 120 miles to get to the park.

Answer:

the function is odd

Step-by-step explanation:

A function f(x) is said to be even if f(-x) = f(x)

On the other hand, f(x) is said to be odd if f(-x)≠ f(x).

We plug in -x in place of x in the given function and simplify;

f(-x) = 3(-x-1)^4

f(-x) = 3[-1(x+1)]^4

f(-x) = 3 *(-1)^4 * (x+1)^4

f(-x) = 3(x+1)^4 ≠ f(x)

Therefore, the function given is odd

Answer:

The given function is odd

Step-by-step explanation:

we need to determine the function [tex]f(x)=3(x-1)^{4}[/tex] is odd or even

Since, A function f(x) is said to be even if [tex]f(-x) = f(x)[/tex]

and f(x) is said to be odd if [tex]f(-x)= - f(x)[/tex] and [tex]f(-x) \neq f(x)[/tex]

We Replace x with -x in the given function and solve;

[tex]f(x)=3(x-1)^{4}[/tex]

[tex]f(-x)=3(-x-1)^{4}[/tex]

take out the negative common,

[tex]f(-x)=3[-(x+1)]^{4}[/tex]

Since [tex](-1)^{4}=1[/tex]

[tex]f(-x)=3(x+1)^{4}[/tex]

[tex]f(-x) \neq f(x)[/tex]

Hence, the given function is odd

Answer:

Option D) h(x), f(x), g(x)

Step-by-step explanation:

we know that

The axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex of the parabola

Part 1) we have

[tex]f(x)=4x^{2} -1[/tex]

This is a vertical parabola open upward

The vertex is a minimum The vertex is the point (0,-1)

The x-coordinate of the vertex is 0

so

The axis of symmetry is x=0

Part 2) we have

[tex]g(x)=x^{2}-8x+5[/tex]

This is a vertical parabola open upward

The vertex is a minimum

Convert the equation into vertex form

[tex]g(x)-5=x^{2}-8x[/tex]

[tex]g(x)-5+16=x^{2}-8x+16[/tex]

[tex]g(x)+11=x^{2}-8x+16[/tex]

[tex]g(x)+11=(x-4)^{2}[/tex]

[tex]g(x)=(x-4)^{2}-11[/tex]

The vertex is the point (4,-11)

The x-coordinate of the vertex is 4

so

The axis of symmetry is x=4

Part 3) we have

[tex]h(x)=-3x^{2}-12x+1[/tex]

This is a vertical parabola open downward

The vertex is a maximum

Convert the equation into vertex form

[tex]h(x)-1=-3x^{2}-12x[/tex]

[tex]h(x)-1=-3(x^{2}+4x)[/tex]

[tex]h(x)-1-12=-3(x^{2}+4x+4)[/tex]

[tex]h(x)-13=-3(x+2)^{2}[/tex]

[tex]h(x)=-3(x+2)^{2}+13[/tex]

The vertex is the point (-2,13)

The x-coordinate of the vertex is -2

so

The axis of symmetry is x=-2

Part 4) Rank their axis of symmetry from least to greatest

1) h(x) -----> axis of symmetry -2

2) f(x) -----> axis of symmetry 0

3) g(x) -----> axis of symmetry 4

so

h(x),f(x),g(x)

Answer:

Yes, there will be enough root beer for everyone to have at least one cup

Step-by-step explanation:

step 1

Find the volume of the cylinder root beer keg

The volume is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=13/2=6.5\ in[/tex] -----> the radius is half the diameter

[tex]h=17\ in[/tex]

substitute

[tex]V=\pi (6.5)^{2} (17)[/tex]

[tex]V=718.25\pi\ in^{3}[/tex]

step 2

Find the volume of the cylinder cups

The volume is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=3/2=1.5\ in[/tex] -----> the radius is half the diameter

[tex]h=4\frac{3}{4}\ in=4.75\ in[/tex]

substitute

[tex]V=\pi (1.5)^{2} (4.75)[/tex]

[tex]V=10.6875\pi\ in^{3}[/tex]

step 3

Multiply the volume of one cup by 50 (the total number of students) and then compare the result with the volume of the cylinder root beer keg

so

[tex]10.6875\pi*(50)=534.375\pi\ in^{3}[/tex]

[tex]534.375\pi\ in^{3}< 718.25\pi\ in^{3} [/tex]

therefore

There will be enough root beer for everyone to have at least one cup

Step-by-step explanation:

THE GIVEN EXPRESSION IS

[tex]\sqrt[3]{\frac{1}{1000c^{9}d^{12} } }[/tex]

To simplify this expression, we just have to apply the cubic root to each part of the fraction, as follows

[tex]\frac{\sqrt[3]{1} }{\sqrt[3]{1000c^{9} d^{12} } }[/tex]

Then, we solve each root. Remember that to solve roots of powers, we just need to divide the exponent of the power by the index of the root, as follows

[tex]\frac{1}{10c^{\frac{9}{3} } d^{\frac{12}{3} } }[/tex]

Therefore, the equivalent expression is

[tex]\frac{1}{10c^{3}d^{4} }[/tex]

So, the right answer is the third choice.

Answer:

x = 5y + 6

Step-by-step explanation:

-5y + 5y = 0

x = 5y + 6

Answer:  

The correct option is C) x = 5y + 6.

Step-by-step explanation:

Consider the provided equation.

[tex]x - 5y = 6[/tex]

We need to solve the equation for x.

Add 5y to both sides of the equation.

[tex]x - 5y+5y = 6+5y[/tex]

Simplify the equation.

x=6+5y

Hence, the value of the equation for x is x=6+5y.

Therefore, the correct option is C) x = 5y + 6.

Answer: Hence, there are 36 total number of invited guests.

Step-by-step explanation:

Let the total number of invited guests be 'x'

Part of those invited had already arrived = [tex]\dfrac{2}{3}x[/tex]

Number of people just arrived = 6

According to question, it brings the number at the party to [tex]\dfrac{5}{6}[/tex] of those invited.

So, it becomes,

[tex]\dfrac{2}{3}x+6=\dfrac{5}{6}x\\\\6=\dfrac{5}{6}x-\dfrac{2}{3}x\\\\6=\dfrac{5x-4x}{6}\\\\6=\dfrac{x}{6}\\\\x=6\times 6\\\\x=36[/tex]

Hence, there are 36 total number of invited guests.

Answer:

42 People

Step-by-step explanation:

P is the total amount of people. Before Cedric arrived, there were (2/3)P people at the party. After Cedric and six other people arrived, there are (2/3)P+7 people at the party. Since this is the same as (5/6)P, we solve (2/3)P+7=(5/6)P to find that P=42.

Answer:

Value of cos B is B)12/13

The value of cos B in triangle ΔABC cannot be definitively determined without additional information such as side lengths. However, assuming a right triangle configuration with an adjacent side of length 12 and a hypotenuse of length 13, the cos B could be calculated as 12/13.

In the triangle ΔABC, the value of cos B can be calculated if we know the measures of the sides of the triangle. Without the values of the sides, we can't give an exact value for cos B. However, from the given options, we would assume that the triangle is a right-triangle, and B is the angle formed by the adjacent side of length 12 and the hypotenuse of length 13. Thus, the value of cos B would be equal to the adjacent side (b) divided by the hypotenuse (c), which matches option B) 12/13.

Remember that in a right triangle:
The cosine of an angle (cos B) is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. This formula, cos B = b/c is a direct application of the Pythagorean theorem.

Final answer:

To find the total combined premium, a 10% discount is applied to the $1,000 homeowner premium, totaling $100 in savings. The new homeowner premium is $900, which is then added to the $1,500 auto premium, resulting in a total combined premium of $2,400.

Explanation:

The student has asked a question about calculating combined insurance premiums when a discount is applied for bundling home and auto insurance. To determine the total combined premium, we'll first calculate the savings on the homeowner premium and then add the reduced home premium to the auto premium.

First, we find 10% of the homeowner premium:

10% of $1,000 = 0.10 * $1,000 = $100 savings.

Next, we subtract the savings from the original homeowner premium to determine the new premium for home insurance:

$1,000 - $100 = $900.

Now, we add the discounted home premium to the auto premium:

$900 + $1,500 = $2,400.

The total combined premium for home and auto insurance would be $2,400 after the 10% discount is applied to the home insurance.
