Answer:
r>0 and V(r)>0
Step-by-step explanation:
Number one: There arent no negative volumes
Number two: There aren't Negative radi
Thus V(r) and r must be more noteworthy than one.
I connect the chart V(r)=5 Pi r^2
The space would be (0,infinity)
The run would be (0, infinity)

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equation represents the situation, where t is the age of the car in years and r is the rate of depreciation. About how old is Devon's car? Use a calculator and round your answer to the nearest whole number.
Given :
Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%.
Its current value is $2,000.
To Find :
Age of car.
Solution :
Price of car after 1 year :
[tex]P_1=P_o(1-0.35)[/tex]
Price of car after 2 year :
[tex]P_2=P_1(1-0.35)\\\\P_2=[P_o(1-0.35)](1-0.35)\\\\P_2=P_o(1-0.35)^2[/tex]
So, price of car after n years.
[tex]P_n=P_o(1-0.35)^n[/tex]
[tex]2000=16000(1-0.35)^n\\\\0.65^n=0.125\\\\n\times log(0.56)=log(0.125)\\\\n=\dfrac{log(0.125)}{log(0.56)}\\\\n=3.58[/tex]
Therefore, age of car in nearest whole number is 4 years.
Hence, this is the required solution.
If a +5 = b + 3 and a + 5 = 12, then b +3=
Answer:
12
Step-by-step explanation:
The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.
Using Transitive Property, it is found that b + 3 is equal to 12.
What is Transitive Property ?The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.
Given;
If a +5 = b + 3 and a + 5 = 12, then we need to find b +3=
So, a + 5 = 12
and a +5 = b + 3
Then b + 3 is also equal to 12. (Transitive Property )
Therefore, Using Transitive Property, it is found that b + 3 is equal to 12.

Which table could represent a function?
1. 1:4,2:2, 3:4, 2:6
2. 1:2, 2:4, 3:6, 4:2
3. 2:6, 0:4, 1:6, 2:2
4. 2:2, 3:2, 4:6, 3:6
The table that represents a function is 1:2, 2:4, 3:6, 4:2.
Option 2 is the correct answer.
Given,
Function table:
1. 1 → 4, 2 → 2, 3 → 4, 2 → 6
2. 1 → 2, 2 → 4, 3 → 6, 4 → 2
3. 2 → 6, 0 → 4, 1 → 6, 2 → 2
4. 2 → 2, 3 → 2, 4 → 6, 3 → 6
We need to find which one is a function.
What is a function?A function has an input and an output.
We can have different inputs and the same output.
Example:
f(x) = x²
x = 1, -1 are the inputs
f(1) = 1
f(-1) = 1
- We see that we have the same output 1 with different inputs 1 and -1.
i.e Many to one
- But we can not have the same inputs and different outputs.
i.e One to many
- We can have one-to-one in a given function.
We have,
1. 1 → 4, 2 → 2, 3 → 4, 2 → 6
Here,
2 → 2 and 2 → 6 = one to many.
We have the same inputs but different outputs which is not possible.
It is not a function.
2. 1 → 2, 2 → 4, 3 → 6, 4 → 2
Here,
1 → 2 and 4 → 2 = many to one
2 → 4 and 3 → 6 = one to one
It is a function.
3. 2 → 6, 0 → 4, 1 → 6, 2 → 2
2 → 6 and 2 → 2 = one to many
This is not possible.
It is not a function.
4. 2 → 2, 3 → 2, 4 → 6, 3 → 6
3 → 2 and 3 → 6 = one to many
This is not possible.
It is not a function.

Jacob buys 6 game tickets and 3 ride tickets at a carnival for $39. Emily buys 2 game tickets and 2 ride tickets for $18. Find the cost of a game ticket and the cost of a ride ticket at the carnival. Set up and solve a system of equations.
Your answer:
Answer:
Cost of ride ticket = $5
Cost of game ticket = $4
Step-by-step explanation:
Given that:
Let ;
game ticket = g
Ride ticket = r
Jacob :
6g + 3r = 39 - - - (1)
Emily :
2g + 2r = 18 - - - - (2)
Divide (2) b y 2
g + r = 9 - - - - (3)
From (3)
g = 9 - r
Substitute ; g = 9 - r into (1)
6(9 - r) + 3r = 39
54 - 6r + 3r = 39
54 - 3r = 39
-3r = 39 - 54
-3r = - 15
r = 5
Put r = 5 in (g = 9 - r)
g = 9 - 5
g = 4
Hence,
Cost of ride ticket = $5
Cost of game ticket = $4

Prove that in a triangle the length of any altitude is smaller than the sides that are meeting at the altitude's vertex.
The proof here would be based on the use of the Pythagoras theorem in trigonometry.
How to prove that the length of the altitude are smallerIn a triangle getting the altitude or height will result to producing a right angled triangle. In trigonometry, a right angled triangle have the sides as the hypotenuse, the adjacent and the opposite. in this case the altitude is either the opposite or adjacent.
From Pythagoras Theorem, the hypotenuse. equals the square root of the sum of squares of the other two sides. hence is the longer side. Each leg of this triangle would be shorter than the hypotenuse. The two sides that meet at the vertex are the adjacent or the opposite and the hypotenuse.

The function y = −0.03x(x− 10) models the jump of a rabbit where x is the horizontal distance (in feet). How long is the rabbit’s jump? what is the rabbits max height?
show step plz
Answer:
x (distance) = 10, max height = .75
Step-by-step explanation:
y=-.03x(x-10)
The distance are the x intercepts: 0 and 10, where 0 is time started and 10 is time ended.
Expand the equation:
y=-.03x^2 +.3x
To find max height you find the vertex
x = -b/2a
x = -.3/-.06 = 5
Plug the x into the equation
y=.-03(5)^2 +.3(5)
y=.75
