At t = 0 the height is not zero because the cannonball is at the end of the barrell of the cannon.
If we define H as the maximum height and T as the time when the cannonball hits the ground, the domain and range are:
domain: [0, T]
range: [0, H]
When time equals 0, why is the height of the cannon ball not equal to 0?
The height is modeled by the graphed parabola.
The height equal to zero would mean that the cannonball is on the ground. Now, at t = 0 we assume that the cannonball is leaving the barrel of the cannon (which is at some given height above the ground). This is why at t = 0 the height of the cannonball is not equal to 0.
Now we also want to describe the domain and range of the graphed function. The domain is the set of the inputs of the function, we can see that it goes from t = 0, when the cannonball is shooted, to a given time T which is when the cannonball reaches the ground.
For the range (the set of the outputs) we can see that it will go from 0 (the ground) to the maximum value that we can see in the graph, a height H.
So, domain: [0, T]
range: [0, H]

The value of x from the equation is 2√2
What are linear equations?
Linear equations are equations with one or two variables.
It is also important to note that the highest power of variable is 1
Given the equation;
yx² = 8y
Let's make 'x' the subject of the equation
Divide both sides by y, we have;
yx²/y = 8y/ y
x² = 8
Take the square root of both sides
(√x²) = √8
The square root takes the square, we have
x = √8
x = √4 × 2
x = 2√2
Thus, the value of x from the equation is 2√2

You have a rock with a volume of 15 cm3 and a mass of 45 g. What's its density?
The formula for density is d = m/v.
d = density
m = mass
v = volume
The volume of the rock is 15 cubic centimeters.
The mass of the rock is 45 grams.
Now just plug these into the formula and solve.
d = 45/15.
45/15 = 3.
The density of the rock is 3 grams per cubic centimeters.
Mass of the rock = 45 g
Volume of the rock = 15 cubic cm
Formula:Density = Mass / Volume
Explanation:By putting the respected values, we get
Density = 45 g / 15 cubic cm = 3 gram/cubic centimeter
Answer:Density of the rock is 3 gram/cubic centimeter.

Refer to the graph to estimate x when f(x)= 7/2
Answer:
x = 4
Step-by-step explanation:
We are asked to find the value of x when [tex] \frac{7}{2} [/tex].
Note that [tex] f(x) [/tex] is also y.
What this means is, what is the value of x when y = 7/2 = 3.5.
On the graph given, trace where y = 3.5. check the x-value that corresponds with it on the point on the line.
Thus, at y = 3.5, x = 4.
Therefore,
x = 4, when [tex] \frac{7}{2} [/tex].

For given question,
Suppose the function for the population growth is,

For t = 13, the population growth of virus would be,
[tex]\Rightarrow A(13)=A_0\times b^{13}[/tex] ..........(2)
But we have been given that a virus takes 13 days to double its original population.
[tex]\Rightarrow A(13)=2\times A_0[/tex] .........(3)
From (2) and (3),
[tex]\Rightarrow A_0\times b^{13}=2\times A_0\\\\\Rightarrow b^{13}=2\\\\\Rightarrow b=1.0548[/tex]
We need to find the number of days to triple its original population
[tex]\Rightarrow A(t)=3\times A_0[/tex] ...........(4)
From (1) and (4),
[tex]\Rightarrow A_0\times b^t=A_0 \times 3\\\\\Rightarrow (1.0548)^t=3\\\\\Rightarrow t=20.6[/tex]
Therefore, a virus takes approximately 20.6 days to triple its original population

Answer:
99
Step-by-step explanation:
Since the question is or, we only need to answer one. For q, there is of course no answer that will not end the division in decimals. So lets move on to p. The only number that is greater than 20 is 99. Also, 99 is divisible by 5, it will just end in decimals. So the answer is 99.

The vertex and range of the given function is y = x + 1 + 3 is (0, 4); - (0, 4); 3 ≤ y ≤ ∞.
What is Domain and Range?The Domain of a function is the set of all possible values that a function satisfies.
The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we put an x value in.
Now the given function is,
y = (x + 1) + 3
or, y = x + 4
Now to find the y coordinate of vertex,
put x = 0 in the given function is,
Thus, we get
y = 4
So, the vertex of the given function is
y = x + 1 + 3 is (0, 4); - (0, 4).
Now for range,Put (x + 1) = 0 in the given function
Thus we get,
y ≤ ∞
and y ≥ 3
Thus the range of the given function will be,3 ≤ y ≤ ∞
Thus, the vertex and range of the given function is y = x + 1 + 3 is (0, 4); - (0, 4); 3 ≤ y ≤ ∞
