1. Omar set off a rocket in a field. The height h of the rocket in feet can be roughly estimated using the formula
h = -16t^2 + 128t, where t is the time in seconds. How long will it take the rocket to reach a height of 240 feet?
2. Josefina tosses a ball upward with an initial velocity of 76 feet per second.
She tosses it from an initial height of 2 feet. Find the approximate time that the ball hits the ground.
Use the function h(t) = -16t^2 + 76t + 2
Round to the nearest second.
3. Brandi, an amateur skier, begins on the "bunny hill," which has a vertical drop of 200 feet.
Her speed at the bottom of the hill is given by the equation v^2 = 64h, where the velocity v is in feet per second
and the height h of the hill is in feet. Assuming there is no friction, approximate Brandi's velocity at the bottom of the hill.
A hybrid car averages 609 miles on a 12.5 gallon tank of gas. Manuel is planning a 1290- mile vacation in his hybrid car. Find how many gallons of gas he can expect to burn.
Using ratio and proportion, we deduced that Manuel's hybrid car travels 48.72 miles per gallon. Based on this, we estimated that Manuel would need around 26.5 gallons of gas for his 1290-mile vacation.
Explanation:The subject at hand requires the utilization of ratio and proportion in mathematics, specifically in the context of fuel economy of cars. The hybrid car Manuel owns averages 609 miles on a 12.5 gallon tank. This implies that for every one gallon of gas, the car can travel 609 / 12.5 = 48.72 miles.
Now Manuel is planning for a 1290-mile trip. To ascertain how many gallons of gas he might expect to consume, we divide the total distance of the vacation by the miles per gallon for his car: 1290 miles / 48.72 miles/gallon = 26.5 gallons.
Therefore, Manuel can expect to consume approximately 26.5 gallons of gas for his 1290-mile vacation.

A toy manufacturer ships a toy in one of two different size boxes. The small box contains 6 of the toy and the large box contains 10 of the toy.
A client orders no fewer than 100 of the toy. Based on his storage and sales needs, the client requires that he receive no more than 8 of the large boxes and no fewer than 6 of the small boxes.
The cost to the client for a small box is $4 and the cost to the client for a large box is $6. The client does not wish to exceed $200 for his order of toys.
Let x represent the number of small boxes and y represent the number of large boxes.
What constraints are placed on the variables in this situation?
Answer:
Let x represent the number of small boxes.
Let y represent the number of large boxes.
The client receive no more than 8 of the large boxes and no fewer than 6 of the small boxes.
[tex]x \geq 6[/tex]

Which equation of the least squares regression line most closely matches the data set?
Note: The variable x represents the years after 1970.
Y= -5.7x-67
Y= -0.98x+65
Y= -0.17x+76
Y= -5.7x +67
Answer:
D. [tex]y = -5.7x + 67[/tex]
Step-by-step explanation:
Let us take the year 1970 as the 0th year.
So, the corresponding table of values is,
x y
0 65

What is a regular polygon?A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
We have a three-dimensional figure is shown in the picture.
As we know,
In the hexagonal prism, there are only two hexagons but in the net, there are three hexagons shown.
Thus, the pattern net is not for the three-dimensional figure which is a hexagon prism the answer is No.

a.all real numbers less than or equal to 4
b.all real numbers less than or equal to −3
c.all real numbers greater than or equal to 4
d.all real numbers greater than or equal to −3
Range of the given function is all real numbers less than or equals to 4.
What is the range of the function?The range of a function is the set of all its output values.
According to the given equation we have
f(x) = -(x+5)(x+1)
Let, y = -(x+5)(x+1)
To find the range of the given function, we will substitute different values of x.
At, x = -5
y = f(-5) = -(-5 +5)(-5+1) =0
At, x = -4
y = f(-4) = -(-4 + 5)(-4 + 1) = -(1)(-3) = 3
At, x = -2
y = f(-2) = -(-2+5)(-2+1) = -(3)(-1) =3
At, x = -3
y = f(-3) = -(-3 + 5)(-3 + 1) = -(2)(-2) =4
Similarly, we will find for the other values of x.
So, the coordinates are (-5, 0), (-4, 3), (-3, 4), (-2,3)
And the graph using this coordinates are already given. Here, the set of outputs are the values of y. So we can see that the range of the given function is all real numbers less than or equals to 4.

Write the first five terms of a sequence. Don’t make your sequence too simple. Write both an explicit formula and a recursive formula for a general term in the sequence. Explain in detail how you found both formulas.
The first five terms of a complex sequence are 4, 7, 10, 16, and 28.
Let's consider a non-trivial sequence.
Let's say the first term of our sequence, a1, is 4.
From then on, the sequence increases by 3 times the previous term, but instead of simply multiplying by 3, we will multiply by 3 raised to the power of one less than the term's position in the sequence. However, we are given that the general expression for the nth term is 4 + 3 x 2(n-2), except for the first term which remains 4.
This gives us a starting point for both our formulas.
To find the first five terms of this sequence, we can manually calculate them using the explicit formula given:
a1 = 4 (by definition)a2 = 4 + 3 x 2(2-2) = 4 + 3 x 1 = 7a3 = 4 + 3 x 2(3-2) = 4 + 3 x 2 = 10a4 = 4 + 3 x 2(4-2) = 4 + 3 x 4 = 16a5 = 4 + 3 x2(5-2) = 4 + 3 x 8 = 28Therefore, the first five terms are 4, 7, 10, 16, and 28.
Explicit Formula:
The explicit formula for any term an in the sequence is:
an = 4 + 3 x 2(n-2) for n > 1, with a1 = 4.
Recursive Formula:
The recursive formula builds each term based on the preceding term. For n > 1, the recursive formula is an = an-1 + 3 imes 2(n-2), with a1 still equal to 4.
