why is x=f(y) the inverse of f(x)?
Answer:
in finding the inverse of an equation, you just switch x and y, so f(x)=y becomes f(y)=x

Two cups are mathematically similar. The larger cup has capacity 0.5 litres and height 8cm. The smaller cup has capacity 0.25 litres. Find the height of the smaller cup
Answer:
The smaller cup has a height of 4cm
Step-by-step explanation:
The two cups have a proportional relationship. This means that the since the smaller cup has a capacity that is half of the larger cup, the height will also be half of the larger cup height.
.25 is half of .5

Which one of the following lines is the graph of the
equation y = 2x - 3?
I'll give you brainliest!
Answer:
Line D
Step-by-step explanation:
The -3 is the y intercept, so the line must cross the y axis at -3.
The 2 is the slope. Slope is rise/run so the line needs to rise 2 for each run of 1 (up 2 right 1).
The only line that does both of these things is Line D.

Need help ASAP please!!! The formula determines the magnitude of an earthquake, where I is the intensity of the earthquake and S is the intensity of a “standard earthquake.” How many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6? Show your work.
Answer:
100
Step-by-step explanation:
M = log(I/S)
The intensity of the first earthquake:
8 = log(I₁/S)
10⁸ = I₁/S
I₁ = 10⁸ S
The intensity of the second earthquake:
6 = log(I₂/S)
10⁶ = I₂/S
I₂ = 10⁶ S
The ratio is:
I₁/I₂ = (10⁸ S) / (10⁶ S)
I₁/I₂ = 100
It is 100 times stronger.
An earthquake with a magnitude of 8 is 100 times stronger than an earthquake with a magnitude of 6.
Given the following data:
Magnitude A = 8Magnitude B = 6To determine how many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6:
Mathematically, the magnitude of an earthquake is given by the formula:
[tex]Magnitude = Log(\frac{I}{S} )[/tex]
Where:
I is the intensity of the earthquake.S is the intensity of a standard earthquake.For earthquake A:
[tex]8=Log (\frac{I_A}{S} )\\\\10^8=\frac{I_A}{S}\\\\I_A=S10^8[/tex]
For earthquake B:
[tex]6=Log (\frac{I_B}{S} )\\\\10^6=\frac{I_B}{S}\\\\I_B=S10^6[/tex]
For strength:
[tex]Strength = \frac{I_A}{I_B} \\\\Strength = \frac{S10^8}{S10^6} \\\\Strength = 10^2[/tex]
Strength = 100

Answer:
M1= 62 M2= 45 M3= 24
Step-by-step explanation:
For angle 1:
180-118 = 62
Angle 2:
180- (73+62)
Angle 3:
part 1
180-73= 107
part 2
180-(107+49)= 24
Answer:
Step-by-step explanation:
You have to solve for 1 before you do anything.
<1 + 118 = 180 The two left angles are supplementary
<1 +118-118=180-118
<1 = 62
Now you can go after angle 2
<1 + 73 + <2 = 180 All triangles have 180 degrees
62 + 73 + <2 = 180 Combine the left
135 + <2 = 180 Subtract 135 from both sides.
135-135+<2 = 180-135 Combine
<2 = 45
Angle 3 is a little trickier because the angle you need to find <3 is not labeled.
73 + x = 180
x = 180 - 73
x = 107
NOw you can find <3
107 + 49 + <3 = 180
156 + <3 = 180
<3 = 180 - 156
<3 = 24
I have left out the reasons for <3. Maybe you can supply them.

Oceanside bike rental shop charges 16 dollars plus 9 dollars an hour for renting a bike.Sam paid 52 dollars to rent a bike.How many hours did he pay to have the bike checked out?
Answer:
4 Hours
Step-by-step explanation:
Since the equation is:
y = 9x + 16
You have to find x
This is the logical way:
52-16 = 36 because thats the starting fee
So 36 divided by 9 equals 4
You do that because 9 is the charge per hr
So he rented it for 4 hours.
Hope this helps:)
A round trip from Montreal to LA is 2,688 miles and takes an airline 9 hours and 20 minutes. Given the outbound trip is the same distance as the return trip, and the speed of the plane was 25%faster on the return trip, how long did the return trip take? Answer to the nearest minute.
Answer:
4.074 hours
Step-by-step explanation:
r =
The formula for speed = Distance × Time
Hence,
Let the outbound speed = r
return trip speed = r + 25x/100 = 125r/100 = 1.25r
Note that: 9 hours and 20 minutes = 9.167
Let t1 and t2 be the time taken to travel on way and return journey.
t1 + t2 = 9 hr 10 min = 9.167 hrs
Hence:
2688/r + 2688/1.25r = 9.167
LCM(1.25r)
(2688 × 1.25) + 2688 /1.25r= 9.167
3360 + 2688 = 9.167 × 1.25r
6048 = 11.45875r
r = 6048/11.45875
Outbound trip rl = 527.8062615904876mph
Return trip speed = r + 25x/100 = 125r/100 = 1.25r
= 1.25 ×
659.75782699mph
Time for return trip = Distance/Speed
= 2,688 miles/659.75782699mph/
= 4.0742222222 hours
Approximately = 4.074 hours
A high school is having a pancake breakfast fundraiser.They have 5 packages of pancake mix that each feed 140 people.The function N(p)=140p represents the number of people,N(P),that packages of pancake mix feed write the domain and range as compound inequalities.
Answer:
They have 5 packages of pancake mix.
N(p) = 140*p
Represents the number of people that can be feed with p = # of packages of pancake mix used.
Now, the domain will be the set of the possible values of p that we can use here.
the set of possible values of p will be:
{0, 1, 2, 3, 4, 5}
We can not use more than 5 because there are only 5 packages.
But we can use actually half a package or a third, so we not should use only whole numbers in the domain, then the domain can be written as:
D = 0 ≤ p ≤ 5
Now, the range is the set of the possible values of N(p)
The minimum will be when p = 0.
N(0) = 140*0 = 0
The maximum will be when p = 5
N(5) = 140*5 = 700
Then the range can be written as:
R = 0 ≤ N ≤ 700
Here we could add another restriction, because we can only feed a whole number of people, then we also should add the restriction that N must be a whole number:
R = 0 ≤ N ≤ 700, N ∈ Z
