A rod is sliding down the side of a wall such that the height is decreasing at a rate of 5 inches per second. If the rod is 174 inches long, what is the rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches?
Answer: The rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches = 1.02675 inches per second.
Step-by-step explanation:
Let h = height, x= distance between the bottom of the rod and the base of the wall.
Given: [tex]\dfrac{dh}{dt}[/tex] = 5 inches per second
Consider the diagram (given in the attachment below):
By Pythagoras theorem, we have
[tex](174)^2=h^2+x^2\ \ (i)\\\\$$30276=35^2+x^2 \ \ \ [h=35 \ in.]\\\\ 30276=35^2+x^2 \\\\ 30276=1225+x^2\\\\ x^2=30276-1225\\\\ x^2 = 29051 \\\\ x=\sqrt{29051}\approx170.447 in.[/tex]
Differentiate both sides of (i) w.r.t t, we get
[tex]0=2x\dfrac{dx}{dt}+2h\dfrac{dh}{dt}\\\\\dfrac{dx}{dt}=\dfrac{-h}{x}\dfrac{dh}{dt}[/tex]
[tex]\dfrac{dx}{dt}=\dfrac{-35}{170.44}(-5)=1.02675\text{ inches per second }[/tex]
Hence, the rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches = 1.02675 inches per second.

Find X pleaseee :).
Answer:
22
Step-by-step explanation:
(5x-7 )+(4x-11)=180 ( it equals 180 because those two angles equal 180)
Then add the similar things together
5x+4x=9x
-7-11= -18
9x-18=180, add 18 on both sides to get 9x alone
9x=180, then divide 180 by 9 to get x alone
x=22
A,B,C, and D are all answer choices
A common way for two people to settle a frivolous dispute is to
play a game of rock-paper-scissors. In this game, each person
simultaneously displays a hand signal to indicate a rock, a piece
of paper, or a pair of scissors. Rock beats scissors, scissors
beats paper, and paper beats rock. If both players select the
same hand signal, the game results in a tie.
Two roommates, roommate A and roommate B, are expecting
company and are arguing over who should have to wash the
dishes before the company arrives. Roommate A suggests a
game of rock-paper-scissors to settle the dispute.
Consider the game of rock-paper-scissors to be an experiment. In the long run, roommate A chooses rock 36% of the time, and
roommate B chooses rock 22% of the time; roommate A selects paper 32% of the time, and roommate B selects paper 25% of
the time; roommate A chooses scissors 32% of the time, and roommate B chooses scissors 53% of the time. (These choices are
made randomly and independently of each other.)
The probabilities were assigned using the
-------------------------
Define event A as the event that roommate A wins the game and thus does not have to wash the dishes.
What is P(A), the probability of event A?
a P(A) = 0.32
b P(A) = 0.22
c P(A) = 0.34
d P(A) = 0.38
Let event C be the event that the game ends in a tie.
What is P(C), the probability of event C?
a P(C) = 0.44
b P(C) = 0.33
c P(C) = 0.55
d P(C) = 0.25
Define event B as the event that roommate B wins the game and thus does not have to wash the dishes. What is the probability
that roommate B wins the game?
a P(B) = 0.67
b P(B) = 0.43
c P(B) = 0.33
d P(B) = 0.50
What is the complement of event A?

A^c = event C
The probability of N is
Answer:
Empirical formula

A^c = event B or event C
Step-by-step explanation:
A = roommate A wins the game
P(A) = (Rock A and Scissors B) + (Scissors A and paper B) + (paper A and rock B)
P(A) = (0.36*0.53) + (0.32*0.25) + (0.32*0.22) = 0.3412
C = game ends in a tie :
P(C) = (RockA and rockB) + (ScissorsA and ScissorsB) + (ScissorsA and ScissorsB)
P(C) = (0.36*0.22) + (0.32*0.53) + (0.32*0.25) = 0.3288
P(B) = 1 - P(A) - P(C)
P(B) = 1 - 0.3412 - 0.3288
P(B) = 0.33

A Hertz Rent-a Car is a car agency charges $40 for one day plus $0.10 per mile to rent a full size car. Enterprise Rent-A-Car charges $18 for one day plus $0.20 cents per mile to rent the same car. How many miles could you drive in one day that would result in the final bill to be the same from both companies?
Answer: 220 miles
Step-by-step explanation:
Let's write the equations for each case:
A Hertz Rent-a Car:
Charges a fixed amount of $40, plus a $0.10 per mile.
Then if you drive x miles, we get a total cost of:
C(x) = $40 + $0.10*x
Enterprise Rent-A-Car:
Chares a fixed amount of $18 plus $0.20 per mile, so if you drive x miles, the cost is:
K(x) = $18 + $0.20*x
Now, we want to find how many miles you can drive such that you would pay the same in both companies.
Then we need to find x such that:
C(x) = K(x)
$40 + $0.10*x = $18 + $0.20*x
Let's solve this for x.
$40 - $18 = $0.20*x - $0.10*x
$22 = ($0.20 - $0.10)*x
$22 = $0.10*x
$22/$0.10 = x
220 = x
So if you drive exactly 220 miles, you would pay the same in both companies.

A cone has a radius of 10 meters and a height of 5 meters. What is the volume of the cone to the nearest cubic meter? Use 3.14 for
Answer:
523.3
Step-by-step explanation:
The volume of a cone is 1/3 hB where h is the height and B is the area of the base.
Step 1: Find the area of the base (B). The base of a cone is a circle so use the formula pi*r^2. Plug in numbers. 3.14*10^2. 3.14*100=314
Step 2: Plug into the formula. 1/3(5*314) --> 1/3(1570)=523.3
Tamara is 7 years older than her sister. The sum of their age is 27.
What is Tamara's age ?
Answer:
17 years old.
Step-by-step explanation:
If Tamara was 7 years younger, she would be as old as her sister. In that case, the sum of their ages would be 20, and since they'd both be the same age, 20 would just be Tamara's sister's age doubled. Half of 20 is 10, so Tamara's sister must be 10 years old, and at 7 years older, Tamara must be 17.
Answer:
17
Step-by-step explanation:
Tamara = x+7
sis= x
x+x+7= 27
2x= 27-77
x= 20/ 2= 10
tamara = 10+7 = 17
