Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.

During a basketball game, one of the players scores 8 points for her team. If the points she scored represent 20% of the team's total points, as shown below, how many points did the team score during the game?
Answers
Answer:
40points
Step-by-step explanation:
Given data
Let the total points the team scored be x
so that
20% of x= 8 points
let us solve for x
20/100*x= 8
0.2*x= 8
0.2x= 8
Divide both sides by 0.2
x= 8/0.2
x= 40 points
Hence the time scored 40points
if i got shorts for 30 dollars and the original price was 40 what was the discount
Answers
Answer:
25%
Step-by-step explanation:
30/40 = 0.75 = 75% paid
100-75 = 25% discount
Answer:
[tex]25\%[/tex]
Step-by-step explanation:
To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;
[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]
Substitute in the given values;
[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]
Solve;
[tex]\frac{10}{40}=\frac{percent}{100}[/tex]
Simplify,
[tex]\frac{1}{4}=\frac{percent}{100}[/tex]
Cross products,
[tex]100 = 4(percent)[/tex]
Inverse operations,
[tex]100=4(percent)\\/4\\\\25 = percent[/tex]

Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answers
Answer:
1005.68 litres
Step-by-step explanation:
Steps to answering this question
Convert miles to kilometers and gallons to litresThen divide the converted miles by the converted gallons Multiply the value gotten from the above step by 100 km1 gallon = 3.78541 litres
13.6 gallons x 3.78541 = 51.48 litres
1 mile = 1.60934 km
321.7 miles x 1.60934 = 517.72 km
Litre needed per kilometer = 517.72 km / 51.48 = 10.06
Litres needed for 100 km = 100km x 10.06 = 1005.68 litres

( it might be wrong pls dont report me just let me kno y its wrong )
Answer:
8.6
Step-by-step explanation:
First of all consider the thousands in the decimal which is 2. Since 2 is not greater than 5 we have to remove the number 2 and 3 from the 8.6023.
We're left with 8.60. Now we see that there's a 0 in the hundredths so since it's not greater than 5 we remove it.
Now we're left with 8.6 which is to the nearest tenth.

4x² + 28x + 49
4x² +14x +14x +49
Factorize
2x ( 2x + 7) +7( 2x + 7)
(2x + 7)²

A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism
Answers
Answer: volume = 5.5625 cubic units.
Step-by-step explanation:
A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.
We know that for a cube with side length L, the volume is:
V = L^3
And we know that these small cubes have an edge length of 1/4 units.
Then the volume of each small cube is:
V = (1/4)^3 cubic units
V = (1/64) cubic units
And the volume of the prism will be 356 times that, then the volume of the prism is:
volume = 356*(1/64) cubic units
volume = 5.5625 cubic units.
