Super Dave Osborne stands at the bottom of a canyon elevation 256 feet below sea level, he throws a piano up at a velocity of 320 feet per second the piano lands on the edge of the cliff at zero elevation . The flight of the piano is modeled by the equation f( x ) = −16t2 2 + 320t − 256. The piano was in the air for exactly how many seconds
Answers
Answer:
The piano was in the air for 18.34 seconds.
Step-by-step explanation:
The height of the piano after t seconds is given by the following equation:
[tex]f(t) = -16t^{2} + 320t - 256[/tex]
Initially, the piano is below the ground level. At the first root of the equation, it will go into the air, and then some time after that it will fall down again, which is at the second root of the equation.
Roots of a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
[tex]f(t) = -16t^{2} + 320t - 256[/tex]
So
[tex]a = -16, b = 320, c = -256[/tex]
[tex]\bigtriangleup = (320)^{2} - 4*(-16)*(-256) = 86016[/tex]
[tex]t_{1} = \frac{-320 + \sqrt{86016}}{2*(-16)} = 0.8348[/tex]
[tex]t_{2} = \frac{-320 - \sqrt{86016}}{2*(-16)} = 19.17[/tex]
Subtracting:
19.17 - 0.8348 = 18.34
The piano was in the air for 18.34 seconds.

Here, F = 2.911
F > 2.739502 , so reject null hypothesis ( H0)
There is ample evidence to indicate a disparity in the means for the different forms of mails.
Step-by-step explanation:
Null hypothesis - H₀: μ₁ = μ₂ = μ₃ = μ₄
Alternative hypothesis - H₁: At least one mean is different.
df1 is factor degree of freedom and df2 is error degree of freedom.
Decision rule - Reject H₀ if F > F₀.₀₅, (df1, df2)
F0.05, df1,df2 is f critical value at \alpha = 0.05
Here df1 = 3 , and df2 = 68
Using Excel,
F₀.₀₅, ₃, ₆₈ = FINV( 0.05, 3 , 68 ) = 2.739502302
So reject H0 if F > 2.739502
Here, F = 2.911
F > 2.739502 , so reject null hypothesis ( H0)
There is ample evidence to indicate a disparity in the means for the different forms of mails.
The landing restuarant order 200 flowers for mother day.the orderd carnation at 1.50$,Rose's at 5.75$and the daisies at 2.60$ each. They order carnation mostly and 20 fewer Rose's than daisies. The total orders came $589.50. How many of each type of flower was ordered?
Answers
Answer:
She ordered 80 carnations, 50 roses, and 70 daisies.
Step-by-step explanation:
Let x = number of carnations, y = number of roses, and z = number of daisies. This problem gives us three equations.
First, remember that we multiply the price of each flower by the number bought then add up the subtotals, that gives the total amount paid.
Therefore,
1.50x + 5.75y + 2.60z = 589.50
Second, the sum of the numbers purchased is the total bought. Therefore,
x + y + z = 200
Finally, there are 20 fewer roses than daisies. Therefore,
y = z - 20
If you substitute z - 20 in for y in the first two equations, you can rewrite them so they only have x and z.
1.50x + 5.75(z - 20) + 2.60z = 589.50
1.50x + 5.75z - 115 + 2.60z = 589.50
1.50x + 8.35z = 704.50
x + (z - 20) + z = 200
x + 2z - 20 = 200
x + 2z = 220
If you solve the rewrite second equation for x, you get x = 220 - 2z. Therefore, you can substitute 220 - 2z in for x in the rewritten first equation, and then solve for z.
1.50 (220 - 2z) + 8.35z = 704.50
330 - 3z + 8.35z = 704.50
330 + 5.35z = 704.50
5.35z = 374.50
z = 70
If you have z = 70, then x = 220 - 2(70) = 80 and y = 70 - 20 = 50.
She ordered 80 carnations, 50 roses, and 70 daisies.

Explanation:Let's say the numbers are 7, 9, 3, 6, 2, 1, 5 (Just as an example)
Because the amount of numbers in this data set is seven, it is an odd number. This means to find the median, we simply have to look at the number in the middle of the set. (In this case, that would be six).

Find an equation in slope-intercept form of the line that has slope 9 and passes through point A(-9, -1).
Answers
Answer:
y = 9x+80
Step-by-step explanation:
We can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = 9x+b
Substitute the point in for x and y
-1 = 9(-9) +b
-1 = -81 +b
Add 81 to each side
-1+81 = b
80 =b
The equation is y = 9x+80

SHOW how much yellow corn and white corn has been planted in the garden.
Please answer using complete sentences. Use of diagrams, tables, or charts will increase grade. Be sure to show your expressions and or equations in your explanation.
Answers
Answer:
There are a total of 84 yellow corns and
840 white corns planted in the garden.
Step-by-step explanation:
Number of plants in each row = 42
Number of rows of yellow corn = 2
Number of rows of white corn = 20
To find the total number of yellow corns planted in the garden, we need to add the number of plants in each row 2 times.
i.e. 42 + 42 = 84
OR
we can say the following:
Total number of yellow corns planted in the garden = Number of rows of yellow corn [tex]\times[/tex] Number of plants in each row
[tex]\Rightarrow 2 \times 42\\\Rightarrow 84[/tex]
To find the total number of white corns planted in the garden, we need to add the number of plants in each row 20 times.
i.e. 42 + 42 + 42 + ....... + 20 times
OR
we can say the following:
Total number of white corns planted in the garden = Number of rows of white corn [tex]\times[/tex] Number of plants in each row
[tex]\Rightarrow 20 \times 42\\\Rightarrow 840[/tex]
Hence, there are a total of 84 yellow corns and 840 white corns planted in the garden.
Tom plants 3 seeds.
The probability that a seed will germinate is 4/5.
A) Calculate the probability that all 3 seeds will germinate.
B) Calculate the probability that at least one of the seeds will germinate.
Answers
Answer:
A. 64/125
B. 124/125.
Step-by-step explanation:
A). As the events ( germinate or not germinate) are independent we multiply the probabilities.
Prob(All seeds germinate) = 4/5*4/5*4/5 = 64/125.
B). Probability of at least one germinating = 1 - probability that none germinate
Probability of 1 seed not germinating = 1 -45 = 1/5.
So Prob(at least one germinating)
= 1 - (1/5 * 1/5 * 1/5)
= 1 - 1/125
= 124/125.
The probability that all 3 seeds will germinate is 64/125 and the probability that at least one of the seeds will germinate is 124/125.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
(A)
The probability of all seeds will germinate will be the product of individual probability since all events are independent.
4/5 × 4/5 × 4/5 = 64/125.
B)
Probability of at least one germinating = 1 - the probability that none germinate
The probability of 1 seed not germinating will be given as,
1 -4/5 = 1/5
Thus, the probability of all three seeds not germinating = 1/5 × 1/5 × 1/5
Thus, the probability that at least 1 of the seeds will germinate.
⇒ 1 - (1/5 × 1/5 × 1/5)
⇒ 1 - 1/125
⇒ 124/125
Hence "The probability that all 3 seeds will germinate is 64/125 and the probability that at least one of the seeds will germinate is 124/125".

Answer:
x =6.0
The base is 6x = 35.8
The side is 3x = 17.9
Step-by-step explanation:
We can use the pythagorean theorem
a^2 + b^2 = c^2
(6x)^2 +(3x)^2 = 40^2
36x^2 + 9x^2 = 1600
Combine like terms
45x^2 = 1600
Divide each side by 45
45x^2 /45 =1600/45
x^2 =35.555555555
Take the square root of each side
sqrt(x^2) = sqrt(35.555555555)
x =5.96284794 = 6.0
The base is 6x = 6*5.9628479 =35.77708 = 35.8
The side is 3x = 3*5.9628479 =17.88854382= 17.9
Answer:
x = 6.0
3x = 17.9
6x = 35.8
Step-by-step explanation:
Using pythagoras theorem
40² = (3x)² + (6x)²
1600 = 9x² + 36x²
1600 = 45x²
x² = 320/9
x = 5.96284794
3x = 17.88854382
6x = 35.77708764
