Answer:
20ft
Step-by-step explanation:
-16t² + 32t + 4
The main goal to find the maximum height is to find the vertex of the parabola because the vertex is always the minimum or the maximum value.
To find the x value of the vertex, use the formula x = 
The a-value is the first coefficient and the b value is the second coefficient:
x = 
x = 1
We can say x = t because t is the x value in the equation.
Now, we can substitute x back into the original equation to find the y-value for the vertex.
y = -16t² + 32t + 4
y = -16(1)² + 32(1) + 4
y = -16(1) + 32 + 4
y = -16 + 32 + 4
y = 20
In a word problem, height is typically the y-value and time is typically the x-value. Since t = x, the answer is 20.
Answer:
La razón de niñas a niños en la guardería es de 2 niñas por cada 3 niños.
Step-by-step explanation:
Una razón es una división entre dos números, generalmente en forma racional (fraccionaria). La razón de niñas a niños en la guardería es la cantidad de niñas dividida por la cantidad de niños de la dicha guardería, Es decir:
La razón de niñas a niños en la guardería es de 2 niñas por cada 3 niños.
Answer:
20
Step-by-step explanation:
Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.
Example : 6, 7, 8 or 6,34,87
Non-Example : 7, 9, 6
As long as the number is greater than the one before it they are consecutive.
Following this rule I have come up with the numbers :
10, 12, 20
These three numbers are consecutive and equal to 42.
Now to find the largest number in this set just look at the greatest value which would be 20.
I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.
I hope this helps! :)
