The height of a thrown ball is a quadratic function of the time it has been in the air. The graph of the quadratic function is the parabolic path of the ball. The vertex of the graph is (1, 20) and the path of the ball includes the point (0, 4). What is an expression that defines this function? Write the quadratic equation in vertex form and in the form y = ax^2 + bx + c.
Answers
An expression that defines this quadratic function is ax² + bx + c = 0.
An expression that defines the quadratic equation in vertex form is equal to y = -16(x - 1)² + 20 and y = -16x² + 32x + 4.
Given the following data:
Vertex, (h, k) = (1, 20).Point (x, y) = (0, 4).What is a quadratic function?A quadratic function can be defined as a mathematical expression that can be used to define and represent the relationship that exists between two or more variable on a graph.
In Mathematics, the graph of any quadratic function is parabolic because it is a u-shaped curve. Also, the standard form of a quadratic function is given by;
ax² + bx + c = 0
Mathematically, the standard equation with the vertex for any parabola is given by:
y = a(x - h)² + k.
where:
h and k are the vertex.a is a point.Substituting the given parameters into the formula, we have;
y = a(x - h)² + k.
4 = a(0 - 1)² + 20.
4 = a + 20
a = -20 + 4
a = -16.
Therefore, an expression that defines this quadratic function is equal to ax² + bx + c = 0.
For the quadratic equation in vertex form, we have:
y = -16(x - 1)² + 20.
y = -16(x - 1)(x - 1) + 20.
y = -16(x² - x - x + 1) + 20.
y = -16(x² - 2x + 1) + 20.
y = -16x² + 32x - 16 + 20.
y = -16x² + 32x + 4.

At x = 1 Amount = 42.50
At x = 2 Amount = 40.
How to illustrate the information?From the information, Malika uses the card to buy one cup of coffee. Each cup of coffee costs $2.50 and the original amount of money on the gift card was $45.
Therefore, the expression representing the amount remaining will be:
A = 45 - (2.50 × x)
A = 45 - 2.50x
At x = 1 Amount remaining will be:
= 45 - 2.50

What is termed as translation vector?The distance vectors that almost all atoms in the grouping are translated through just to form another cluster inside the solid are defined by translation vectors.
Tv can be in either Cartesian or internal coordinates. If a Tv is described in Cartesian coordinates, it is directly used. If it is defined in internal coordinates, it is converted to Cartesian coordinates as well as the Cartesian coordinates of atom 1 (real or dummy) are subtracted from it at run time. If atom 1 is at the origin, i.e. (0.0, 0.0, 0.0), then the coordinates defined by Tv are indeed the translation vectors; this simplifies visualizing this same translation vectors using a GUI because a line drawn from atom 1 to Tv would represent this same translation vector.Now, as per the stated question;
The horizontal (lateral, x) change is represented by the number 12. This same player runs 12 yards to the left.

Answers
The area that is not covered by the sprinkler is 33.49 m².
The sprinkler is placed in one corner of the garden.
It has a reach of 8 m.
radius = r = 8 m
It means that it will form a segment of 90°.
So, the area it should cover will be:
Area that should be covered = 1 / 4 π r²
= 1 / 4 π (8)² m²
= 1/ 4 π (64) m²
= 16 ( 3.14 ) m²
= 50.24 m²
Now, it only rotates 30°.
It means that, it covers only 1 / 3 area.
So, the area actually covered = 1 / 3 × 50.24 m²
= 16.75 m²
The area that is not covered = 50.24 m² - 16.75 m²
The area that is not covered = 33.49 m²
Therefore, we get that the area that is not covered by the sprinkler is 33.49 m².

Where,
P(A) is the probability of an event “A”
n(A) is the number of favorable outcomes
n(S) is the total number of events in the sample space.
Given,
At a carnival, the object of a game is to throw a dart at the board and hit region III.
Here we need to find the probability that it hits region IV.
Consider the board was look like the following figure.
Then based on the given figure,
First, we have to find the total area of the board and the area of the required region.
And then we have to compare it to calculate the Probability.
So, the total area of the board is,
=> total area of the board = (10 + 30)(10 + 15)
=> total area of the board = 1000 in²
Now, the The area of the region IV is
=> Area = (10)(30)
=> Area = 300 in²
Therefore, the probability that it hits region IV is
=> P = 300/1000
=> P = 30/100
=> P = 30%

Using translation concepts, the formula for function g(x) is given by the following option:
D. g(x) = 2^(x - 2)
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
From the graph of the functions, we have that:
f(x) = 2 when x = 1.g(x) = 2 when x = 3.f(x) = 4 when x = 2.g(x) = 4 when x = 4.This means that g(x) is a shift right of 2 units of f(x), that is:
g(x) = f(x - 2).

Your dog takes off from your house after seeing a cat run across the street. If your dog started from rest and achieved 5.5 m/s in 3 seconds, what is the acceleration of your dog?
Answers
The acceleration of the dog is approximately 1.83 meter per second² .
Acceleration is defined as the rate of change of velocity . The change in velocity per unit time is acceleration.
The formula to calculate acceleration is given by acceleration = velocity ÷ time.Negative acceleration is called deceleration.Acceleration can be uniform or non-uniform.In the given problem the dog started from rest and achieved the final velocity of 5.5 m/s.
Let us use Newton's laws to write the equation:
v = u + at , where v is the final velocity , u is the initial velocity , a is acceleration and t is time.
The dog starts from rest so the initial velocity is 0.
given v=5.5 /s and t = 3 seconds
putting the values we get:
v = u + a t
or , 5.5 = 0 + 3a
or, a = 5.5/3 meters per seconds²
or, a = 1.8333... m/s²
or, a ≈ 1.83 m/s²
