A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=-16x^2+228x+71
Answer:
883.3
Step-by-step explanation:
thats all.
An equation is formed of two equal expressions. The maximum height reached by a rocket, to the nearest tenth of a foot is 883.3 feet.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To find the maximum height through which the rocket will reach, we need to differentiate the given function, therefore, we can write,
y=-16x²+228x+71
dy/dx = -16(2x)+228
Substitute the value of dy/dx as 0, to get the value of x,
0 = -32x + 228
228 = 32x
x =7.125
Substitute the value of x in the equation to get the maximum height,
y=-16x²+228x+71
y=-16(7.125²)+228(7.125)+71
y=883.3feet
Hence, the maximum height reached by the rocket, to the nearest tenth of a foot is 883.3 feet.

An education budget went from $800,000 to $900,000. What is the approximate percent increase? The approximate percent increase is 13%. The approximate percent increase is 89%. The approximate percent increase is 98%. The approximate percent increase is 113%.
Answer:
The answer is 13%
Step-by-step explanation:
The approximate percent increase is 13%.
What is Percentage Increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage. To calculate the percentage we need to have the initial value and the increased (new) value. In other words, we can say that percentage increase is a measure of percent change which gives the extent to which a quantity gains magnitude, intensity, or value. If the percentage increase is a negative value, then we can say that there is a percentage decrease of the same magnitude.
Percentage Increase FormulaFollowing the concept of percentage increase, the percentage increase formula is derived and expressed as: Percentage Increase = [(Final Value - Initial Value)/Initial Value] × 100. It should be noted that since the percentage has to be a positive quantity, we take the absolute value of the initial value. If the percentage increase is a negative value, then it is a percentage decrease. The percentage increase is the relative change in the quantity with respect to its initial value. If the percentage change is positive, then it is the percentage increase and if the percentage change is negative, it is a percentage decrease.
Given:
initial =$900,000
Final = $900,000
% increase = $900,000- $800,000/ $800,000 * 100
% increase = 100, 000/8000
% increase = 12.5 %

Answer:
1 fourth of 52 is 13 so i think its 13 tell me if ibam wrong
Answer:
There is a 33% percent chance.
Step-by-step explanation:
You could use the formula, desired probability out of total outcome options
So basically, it would be 52/3 to get how much a fourth of the cards are, which is 13
13/52=0.25*100=25%
Jeff mowed a lawn for $20.00 and received a $5,25 tip. He then washed a car for $12.50. How much money

Answer:
See below.
Step-by-step explanation:
Mowing the lawn: $20
Tip: $5.25
Add them together.
[tex]20+5.25=25.25[/tex]
Washing the car: $12.50
Add that to the amount.
[tex]25.25+12.50=37.75[/tex]
Answer: [tex]37.75[/tex]
:)
Answer "and" Explanation:
Depends on whether this is a simple math problem or a riddle. I’m assuming the latter so…
Jeff received $20.00 for providing a lawn mowing service. Jeff received an additional $5.25 tip. Ignoring costs and taxes, Jeff’s gross receipts were $25.25.
Jeff then decided to wash a car. The ways it’s worded leads me to believe he spent $12.50 on the car wash.
So, $25.25 - $12.50 = $12.75
Alternatively, if Jeff was paid to wash the car then:
$20.00 + $5.25 + 12.50 = $37.75
So the Answer will be: $37.75
