The plane continued to descend, but leveled off to an angle of descent of 3° degrees for approximately 2 miles. How many feet did they drop in altitude (d)? Round to the nearest 10th.

Answers

ANSWER: Plane dropped 6097 feet in altitude.
BECAUSE: An airplane is at point A from where it continued to descend by 30° for an approximate distance of 2 miles
∠ACB = Angle of descent = 30°
Distance BC = 2 miles
Let the plane dropped the altitude = h miles
Now tan 30° =


h = 1.155 miles
h ≈ 1.16 miles
Since 1 mile = 5280 feet
1.15 miles = 5280×1.16 feet
= 6097 feet
Therefore, the plane dropped by 6097 feet vertically.

Suzy makes 20 dollars an hour at her job. Bill only makes 10 dollars an hour but he has a starting bonus of 20. When will Suzy and Bill make the same amount of money for the same number of hours worked? How much will they both earn at the same time?

Answers

Answer:

2 hours

Suzy would earn $40

Bill will earn $40

they will both earn $80

Step-by-step explanation:

The total amount suzy earns is a function of the total hours worked. Let t represent time

total income of suzy = $20t eqn 1

Bill's income = starting bonus + variable pay

= $20 + $10t

We are looking for when they would earn the same amount :

20t = $20 + $10t  eqn 2

collect like terms and solve for t

10t = $20

t = 2 hours

Substitute for t in either eqn 1 or 2

20(2) = $40

Suzy would earn $40

Bill will earn $40

they will both earn $80

a car with an initial value of $23,00 is decreasing in value at a rate of 8% each year. Write a function, f(x), that expresses the value of the car in x years

Answers

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r/n)^ nt

Where

A represents the value after t years.

n represents the period for which the decrease in value is calculated

t represents the number of years.

P represents the value population.

r represents rate of decrease.

From the information given,

P = 23000

r = 8% = 8/100 = 0.08

n = 1

Therefore, the exponential decay function described in this situation is

A = 23000(1 - 0.08/n)1)^ 1 × t

A = 23000(0.92)^t

If A = 15000, then

15000 = 23000(0.92)^t

0.92^t = 15000/23000 = 0.6522

Taking log of both sides to base 10

Log 0.92^t = log 0.6522

tlog 0.92 = log 0.6522

- 0.036t = - 0.1856

t = - 0.1856/- 0.036

t = 5 years to the nearest year

Help pls! (4c+4)(2c-3)

Answers

Answer:

8c2 - 4c - 12

Step-by-step explanation:

Answer:

8c^2-4c-12

Step-by-step explanation

So you have to multiply 4c into 2c and -3 first and then 4 into 2c and -3.

(4c+4)(2c-3)

4c X 2c is 8c^2

(4c+4)(2c-3)

4c X -3 is -12c

So for the 4c multiplying in you would get 8c^2 and -12c, but we still have to multiply in the 4

4 X 2c is 8c

(4c+4)(2c-3)

4 X -3 is -12

So then we would get 8c^2-12c+8c-12, however we can still combine the -12c and the 8c.  Combining those would get -4c.  So the final answer is 8c^2-4c-12

What is this ?????? plz helpppp Ok ok ok I know posted another idea ready for feedback earlier but here's another one.A bookstore where the different genres are actually themed. So nonfiction would be the main room and to a newcomer, it would be the only thing they saw but if they were to ask where the mystery books were the clerk/employee (this employee would have a very unassuming generic uniform so they don't stand out) would hand them their first clue (all sneaky-like) to find the hidden door to the mystery section! (There would be 3 doors to the room and every month or so the clues and door that is unlocked/can be used to access the mystery room would be changed). The mystery section would be themed kinda like sherlock holmesy, all old stuff and things that would look like clues ("blood" stains, broken lamps, magnifying glasses, books open on the desk et cetera). The fantasy section door would be accessed by pulling a large tasseled cord which would trigger a large bell to ring and the door would pop open close to them. This room would have large "trees" in each corner that have the traits of each season with different ornate lamps hanging from the boughs along with different iconic items from famous fantasy books. To get to the sci-fi section there would just be a LARGE red button with no markers that a person could press to enter the "control deck". After they press the button the doors would slide open and the room would be bathed in red light with a voice playing over the loudspeaker giving the button pusher urgent instructions to save the spaceship from disaster (which would be different on specific days of the week). The inside would look like a spaceship "control deck" with a control panel consisting of different buttons and switches that must be activated in accordance with the voice over the loudspeaker (the buttons and switches would also make sound). An employee would be in a backroom controlling the lights in the whole building (all the lights would turn off if the button pusher failed to press the right buttons in the right order in time) if they do succeed the employee would come out, congratulate them, and see if they need any help finding anything. If they fail they would come out and push a couple of buttons so that the lights 'come back on' (the lights would be on a 10-15 sec timer or something and turn on on their own). The dystopian fiction section is underneath the fantasy section and has a steampunk theme. It is accessed by a trapdoor in the floor. The horror section would be accessed by pulling a random skull lever in the main room which would give the client a skull key with a tag that has an eerie rhyme telling the client where to find the door. The door would look ornate and creepy and it would have a dead-looking 'tree' (not a real tree there will be various plants to give the building life but yeah not this one) with an animatronic crow or two on it occasionally crowing. The clerk at the cash register would automatically ask for the key when they check out. Example: "Did you visit the horror room today? Yes? Okay, kindly return the key of Hades. Thank you. Have a nice day!" Or something like that with an equally creepy or creepier name for the key. Okay, that's all I have for now but answer with your feedback and ideas for other room genres if you have them! Thanks so much! EXTRA POINTS---Set up an equation and find the value of x.
