In Cincinnati, fireworks are launched from a large barge on the Ohio River for a Labor Day celebration.
Their flight can be modeled by the function h(t) = -4.9(t - 4)2 + 80, where h is the height in meters and t is the time in seconds.
Suppose that buildings obstruct the fireworks. So, the barge is relocated 30 meters to the east.
Write a function to model the path of the fireworks in the new location.
The function to model the path of the fireworks in the new location is -4.9(t - 4)^2 + 50
Equations and expressionGiven the height reached by the flight expressed as:
h(t) = -4.9(t - 4)^2 + 80
If the barge is relocated 30 meters to the east, the new function will be derived by subtracting 30 from the initial function
New function = -4.9(t - 4)^2 + 80 - 30
New function = -4.9(t - 4)^2 + 50
Hence the function to model the path of the fireworks in the new location is -4.9(t - 4)^2 + 50

Answer:
Angles on a straight line add up to 180 degrees so for the 129 degrees you will take 180 - 129 = 51. In the triangle you will add 51 and 55 = 106 but remember in a triangle all angles should be equal to 180. So 180 - 106 = 74. X=74degrees
Juan wants to change the shape of his vegetable garden from a square to a rectangle, but keep the same area so he can grow the same amount of vegetables. The rectangular garden will have a length that is 2 times the length of the square garden, and the width of the new garden will be 16 feet shorter than the old garden. The square garden is x feet by x feet. What is the quadratic equation that would model this scenario? x2 = (2x)(x – 16) x2 = (x)(x – 16) x2 = (x)(x 16) x2 = (2x)(x 16).
The quadratic equation that would model this scenario is
[tex]x^{2} = 2x(x-16)[/tex]
Let us take the side of the square = x
Area of the square = x²
Length of the rectangular garden = 2x
Width of the rectangular garden = x-16
So, the area of the new vegetable garden = length*width
Area of the new or rectangular vegetable garden = 2x(x-16)
What is a quadratic equation?The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by [tex]ax^2+bx+c[/tex]coefficient [tex]x^{2}[/tex]non-zero.
Since it is given that
Area of square garden = area of the rectangular garden
[tex]x^{2} = 2x(x-16)[/tex]
Thus, the quadratic equation that would model this scenario is
[tex]x^{2} = 2x(x-16)[/tex]

A quadrilateral has angles that measure 115, 97, and 68. What is the measure of the missing angle?
The sum of all the angles of any quadrilateral is 360 degrees
115 + 97 + 58 + missing angle = 360
missing angle = 90 degrees
Hope that helps!
Answer:
90
Step-by-step explanation:
Since sum of all the angles of any quadrilateral is 360 degrees
115 + 97 + 58 + x = 360
Solve for x:
Add the numbers
270 + x = 360
Rearrange terms
x + 270 = 360
Subtract 270 from both sides of the equation
x + 270 - 270 = 360 - 270
Simplify
x = 90
Missing angle = 90

the zoo has 400 employess 72 percent of them are part time employess how many employess work full-time
Answer:
112
Step-by-step explanation:
There are 400 employees. If 72 of them work part-time, then 72% of 400 = 400*72%. This equals 288. Then you subtract that from 400 because the rest of them should be full-time workers. 400-288=112.
Answer:
112
Step-by-step explanation:
400 x 0.72 = 288, so that's the number of part-time employees.
400 - 288 = 112

Unit 8: right triangles & trigonometry date: ________________________ per: _______ homework 2: special right triangles.
The sides and angles of a triangle can be determined using trigonometry ratios
The values of x, y and z are [tex]x = 14\sqrt 2[/tex], [tex]y =14[/tex] and [tex]z = 14\sqrt 3[/tex]
How to determine the missing values of the triangleThe upper triangle is a right triangle with an angle measure of 45 degrees.
So, the value of x is:
[tex]x = 14\sqrt 2[/tex]
Next, we calculate the hypotenuse (h) of the lower triangle using:
[tex]h^2 = (14\sqrt 2)^2 + (14\sqrt 2)^2[/tex]
So, we have:
[tex]h^2 = 784[/tex]
Take the square roots of both sides
[tex]h = 28[/tex]
The value of y is then calculated using the following sine ratio
[tex]\sin(30) = \frac y{28}[/tex]
Make y the subject
[tex]y =28 * \sin(30)[/tex]
Evaluate
[tex]y =14[/tex]
The value of z is then calculated using the following cosine ratio
[tex]\cos(30) = \frac z{28}[/tex]
Make z the subject
[tex]z =28 * \cos(30)[/tex]
Evaluate
[tex]z =28 * \frac{\sqrt 3}{2}[/tex]
[tex]z = 14\sqrt 3[/tex]
Hence, the values of x, y and z are [tex]x = 14\sqrt 2[/tex], [tex]y =14[/tex] and [tex]z = 14\sqrt 3[/tex]

Edward drove 275 miles in 212 hours and 357.5 miles in 314 hours. If he drove at a constant rate, how much distance did he travel every hour? Enter your answer in the box below.
The average distance that he travelled every hour is; 2.4357 miles per hour
What is the average distance?He drove 275 miles in 212 hours.
Now, to find the rate of distance per hour;
Distance per hour = 275/212 = 1.2972 miles per hour
He drove 357.5 miles in 314 hours.
Distance per hour = 357.5/314
Distance per hour = 1.1385 miles per hour
Thus, his average distance per hour = 1.2972 + 1.1385 = 2.4357 miles per hour

Answer:
Train A : 143 tons ; Train B : 18 tons
Step-by-step explanation:

What is chain rule in probability?For two events A and B, by chain rule, we have:
[tex]P(A \cap B) = P(B)P(A|B) = P(A)P(A|B)[/tex]
What is law of total probability?Suppose that the sample space is divided in n mutual exclusive and exhaustive events tagged as
[tex]B_i \: ; i \in \{1,2,3.., n\}[/tex]
Then, suppose there is event A in sample space.
Then probability of A's occurrence can be given as
[tex]P(A) = \sum_{i=1}^n P(A \cap B_i)[/tex]
Using the chain rule, we get
[tex]P(A) = \sum_{i=1}^n P(A \cap B_i) = \sum_{i=1}^n P(A)P(B_i|A) = \sum_{i=1}^nP(B_i)P(A|B_i)[/tex]
How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as [tex]X_1, X_2, ... , X_n[/tex] values of Y are there as [tex]Y_1, Y_2, ..., Y_k[/tex]rows and left to the columns. There will be [tex]n \times k[/tex]values will be formed(excluding titles and totals), such that:
Value([tex]i^{th}[/tex] row, [tex]j^{th}[/tex] column) = Frequency for intersection of [tex]X_i[/tex] and [tex]Y_j[/tex]values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
Suppose that two events are denoted by A and B.
They are said to be independent event if and only if:

The events A, B,C,D and E are given as:
A: The employee is male. B: The employee is female. C: The employee takes public transportation. D: The employee takes his/her own transportation.E: The employee takes some other method of transportation.Checking all the listed options one by one, for them being independent:
Case 1: A and CP(A) = P(The employee is male. ) = 36/60
P(C) = P(The employee takes public transportation.) = 20/60[tex]P(A \cap C) = 12/60 \\\\ P(A)P(C) = \dfrac{36 \times 20}{60^2} = 12/60[/tex]
[tex]P(A \cap C) = P(A)P(C)[/tex]
Thus, A and C are independent events.
Case 2: A and DP(A) = P(The employee is male. ) = 36/60
P(D) = P(The employee takes his/her own transportation.) = 30/60
[tex]P(A\cap D) = 20/60\\\\P(A)P(D) = \dfrac{30 \times 36}{60^2} = 12/60 \neq P(A \cap D)[/tex]
Thus, A and D are not independent events.
Case 3: B and DP(B) = P(The employee is female. ) = 24/60
P(D) = P(The employee takes his/her own transportation.) = 30/60
[tex]P(B \cap D) = 10/60 \neq P(B)P(D)=\dfrac{24 \times 30}{60^2} = 12/60[/tex]
Thus, B and D are not independent events.
Case 4: B and EP(B) = P(The employee is female. ) = 24/60
P(E) = P(The employee takes some other method of transportation.) = 10/60
[tex]P(B \cap E) = 6/60 \neq P(B)P(E)= \dfrac{24 \times 10}{60^2} = 4/60[/tex]
