A ball is thrown into the air with an upward velocity of 80 feet per second. The function
h = -16t2 + 80t models the height h, in feet, of the ball at time t, in seconds. When will the ball reach the ground?
after 3 seconds
after 4 seconds
after 5 seconds
after 6 seconds
Best explanation gets Brainliest!!
Answer:
After 5 seconds
Step-by-step explanation:
One is given the following expression to model to the flight path of a ball:
[tex]h=-16t^2+80t[/tex]
In this problem, one is asked to find the time at which the ball lands on the ground. The easiest way to do so is to factor the expression. Take out factors that both terms have in common. The one will set the equation equal to zero, as this is the height at which one wants to find the time for. Finally, use the zero product property to solve. The zero product property states that any number times zero equals zero. Apply these ideas to the given function:
[tex]h=-16t^2+80t[/tex]
Factor the expression; both terms have a common factor of (-16t):
[tex]h=-16t^2+80t[/tex]
[tex]h=-16t(t-5)[/tex]
Set the equation equal to zero to solve for when the ball has a height of zero or rather lands on the ground:
[tex]h=-16t(t-5)[/tex]
[tex]0=-16t(t-5)[/tex]
Now use the zero product property, this states that any number times zero equals zero. Set each of the factors equal to zero, and solve to find the value of (t) for which the factor will equal zero:
[tex]0=-16t(t-5)[/tex]
[tex]0=-16t[/tex] [tex]t - 5 =0[/tex]
Solve for the value (t) using inverse operations,
[tex]0=-16t[/tex] [tex]t - 5 =0[/tex]
(divide by (-16) (add (5))
[tex]0=t[/tex] [tex]t=5[/tex]
As one can see, the ball started on the ground, therefore at (0) seconds, its height was (0). Then, after (5) seconds the ball landed on the ground, therefore, after (5) seconds its height was again (0).

A soda company had sales of $35,107 million in 2010 and $45,984 million in 2014. Use the Midpoint Formula to estimate the sales in 2012. Assume that the sales followed a linear
pattern.
$ __ million
Answer:
40545.50 mill
Step-by-step explanation:
so the average rate from 2010 to 2014 is a change of 4 years with a increase of 2719.25 milllion per year so if that rate started at the 2010 value (35107 million) then if you add the average rate twice you get how much they would of made in 2012 so 35107 plus 2719.25 plus 2719.25 you get 40545.50 million so that the answer oh yea and its like a 5 million pattern over 2 years that why average rate is 2.5ish
Suppose that NOP is isosceles with base.
Suppose also that and.
Find the degree measure of each angle in the triangle.
Step-by-step explanation:
In isocseles triangle, base angles are equal :
base angles are angle N and angle P:
angle N=angle P
3x+17=4x+2
4x-3x=17-2
x=15
For angle N:
subtitute x in angle N
=3(15)+17
=45+17
=62
For angle P:
subtitute x in angle P:
=4(15)+2
=60+2
=62
For angle O:
sum of all angles in a triangle is 180.
angle N +angle P+angle O=180
62+62+angle O=180
angle O=180-62-62
angle O=56

A and B are vertical angles. If m A = (4x + 8)° and m B = (2x + 28)°,
then find the value of x.
Answer:
x = 10
Step-by-step explanation:
By the Vertical Angles Theorem that states the vertical angles are congruent.
4x+8 = 2x + 28
-8 -8
-----------------------
4x = 2x + 20
-2x -2x
-------------------------
2x = 20
/2 /2
--------------------------
x = 10
Answer:
[tex](4x + 8) = (2x + 28) \\ \\ 4x + 8 = 2x + 28 \\ \\ 4x - 2x = 28 - 8 \\ \\ 2x = 20 \\ \\ x = \frac{20}{2} \\ \\ x = 10[/tex]
Vertical angel are always Equal ( = )

Hey there! I'm happy to help!
A translation is just when they are staying the same. You just move the figure along but it doesn't switch the way it is facing.
A reflection is when it is like going over a mirror. It's kind of like it rolls over. So if you are facing left on the ground and you roll over then you are facing the right. That's basically what a reflection is.
A rotation is pretty self explanatory, it's when you twist it sideways, upside down, etc. A rotation can also end up in the same position as a reflection. For example if you diagonally reflect something it is the same as a 180 degree rotation, and that might be what is stressing you out.
With your answers, I'm assuming each number has all three possible answers, so if one seems to have both, just see which answer you haven't used yet.
1) Rotation, Translation Reflection
2) Rotation, Reflection, Translation
3) Translation, Rotation, Reflection
4) Rotation, Reflection, Translation
5) Reflection, Rotation, Translation
6) Reflection, Rotation, Translation

Answer:
loss = 24, loss % = 10
Step-by-step explanation:
amount he spent = 12*20 = 240
amount he earnt = 12*18 =216
loss = 240-216 = 24
loss % = 24/240 x 100% = 10%

yes
Step-by-step explanation:
Find the largest prime factor of 18! + 19! + 20!
18! is common to each term in the sum:
18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400
The largest prime factor of 18! is of course 17.
Meanwhile,
400 = 16×25 = 2⁴×5²
so the largest prime factor of 18! + 19! + 20! is 17.

25 POINTS, I DONT UNDERSTANDDDDDD :C WHAT IS SO MISLEADING ABOUT THIS GRAPH???
Answer:
honestly, the graph look totally fine...
If one ere pressed to find something to complain about it, one could suggest that you do not know if this was the starting price of the stock or the ending price of the stock each day?... One could also argue that to be a bit more meaningful you might want to know the range of prices during each day...

how do you solve this problem
Answer:
(-6,1)
Step-by-step explanation:
-x + y = 7 [Equation (1)]
2x + 5y = -7 [Equation (2)]
Multiplying equation (1) by 5, to make the coefficients of y equal in both equations.
5(-x + y) = 5(7)
=> -5x + 5y = 35 [Equation (3)]
Subtracting equation (3) from equation (2).
(2x + 5y) - (-5x + 5y) = -7 - 35
=> 2x + 5y + 5x - 5y = -7 - 35
=> 7x = -42
=> x = -42/7
=> x = -6
Putting the value of x in equation (1).
-(-6) + y = 7
=> 6 + y = 7
=> y = 7 - 6
=> y = 1
So, x = -6 and y = 1.
