A ball is thrown upward with an initial velocity of 75 feet per second and an initial height of 4 feet. Given h(t) = −16t2 + v0t + h0, complete function h to model the vertical motion of the ball. Then find the ball’s maximum height, to the nearest foot.
The maximum height of the ball is given as follows:
92 feet.
How to model the height of the ball?The quadratic function modelling the height of the ball is given as follows:
h(t) = -16t² + v(0)t + h(0).
In which:
v(0) is the initial velocity.h(0) is the initial height.The parameters for this problem are given as follows:
v(0) = 75, h(0) = 4.
Hence the equation is:
h(t) = -16t² + 75t + 4.
The coefficients are given as follows:
a = -16, b = 75, c = 4.
As the quadratic equation is concave down, the maximum height is at the vertex.
The t-coordinate of the vertex is given as follows:
t = -b/2a
b = -75/-32
b = 2.34375s.
Hence the maximum height is of:
h(2.34375) = -16(2.34375)² + 75(2.34375) + 4.
h(2.34375) = 92 feet.

If 2 similar regular hexagons have areas of 25√3 cm² and 16√3 cm² respectively. What is the scale factor from smaller to larger pentagon?
Answer:
The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths.
In this case, we have two similar regular hexagons. Let x be the side length of the smaller hexagon, and y be the side length of the larger hexagon. Then, we have:
Area of smaller hexagon / Area of larger hexagon = (x^2 * 6 * sqrt(3)) / (y^2 * 6 * sqrt(3)) = x^2 / y^2
We are given the areas of the two hexagons:
x^2 * 6 * sqrt(3) = 16 * sqrt(3)
y^2 * 6 * sqrt(3) = 25 * sqrt(3)
Dividing the second equation by the first equation, we get:
(y^2 * 6 * sqrt(3)) / (x^2 * 6 * sqrt(3)) = 25 * sqrt(3) / (16 * sqrt(3))
Simplifying this expression gives:
y^2 / x^2 = 25 / 16
Taking the square root of both sides, we get:
y / x = 5 / 4
Therefore, the scale factor from the smaller hexagon to the larger hexagon is 5/4.
4) The length and width of a rectangular box
are 10 in. and 8 in., respectively. Another
rectangular box has a length of 15 in. and a
width of 12 in. respectively. Are the length
and width dimensions of the two rectangular
boxes similar?
Answer:
Step-by-step explanation:
Yes, the length and width dimensions of the two rectangular boxes are similar.
Two objects are considered similar if they have the same shape, but not necessarily the same size. The ratio of the corresponding sides of two similar objects is called the scale factor.
For the first rectangular box, the ratio of length to width is 10/8, which can be simplified to 5/4.
For the second rectangular box, the ratio of length to width is 15/12, which can be simplified to 5/4 as well.
Since the ratio of the corresponding sides of the two boxes is the same, namely 5/4, we can conclude that the length and width dimensions of the two rectangular boxes are similar.
In the picture does this represent a function??
Because,
It satisfies the vertical line test and represents a function.
What is function ?
Function can be defined in which it relates an input to output.
Based on the image you provided, it seems to represent a function since each input value (x-value) corresponds to a unique output value (y-value) and there is only one output value for each input value.
To verify if a graph represents a function, we can use the vertical line test. If a vertical line intersects the graph at more than one point, then the graph does not represent a function. However, in this graph, for any vertical line drawn, it only intersects the graph at one point.
Hence, it satisfies the vertical line test and represents a function.

If the short leg of a 30-60-90 triangle measures 203, the long leg measures how much ?
We can state this by responding to the provided question Hence, the triangle longer limb is around 351.42 in length.
What precisely is a triangle?A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.
In a triangle with three legs measuring 30, 60, and 90, the shorter leg is half as long as the hypotenuse while the larger leg is sqrt3 times as long.
Let's name the larger leg's length "x" for simplicity. Thus, we are aware of:
The shorter leg measures 203 in length.
The hypotenuse measures 406 times the length of the shorter leg.
Using the proportion of the hypotenuse and leg lengths in a 30-60-90 triangle, we may find:
x = sqrt3 times ($) 203 = 351.42$
Hence, the longer limb is around 351.42 in length.

How do I evaluate the limit? How do I know which theorems to use
In the polynomial function given, the value of the limit as it approached infinity is 5/3
What is the value of the limitTo evaluate this limit, we need to determine the behavior of the function as x approaches infinity. To do this, we can use the fact that for any polynomial p(x) and q(x) of the same degree, the limit of p(x)/q(x) as x approaches infinity is equal to the ratio of the leading coefficients.
In this case, both the numerator and denominator are polynomials of degree 2, so we can apply this property. The leading coefficient of the numerator is 6 and the leading coefficient of the denominator is 7. Therefore, the limit as x approaches infinity of the given expression is:
lim [ (6x² - 5) / (7x² + x - 3)]
x → ∞ = 5/3

The graph shows the total cost c of buying one large bucket of popcorn and d large drinks. Write an equation from the graph that could be used to find the total cost c if you buy one large bucket of popcorn and d large drinks.
Answer:
[tex]y = 4d + 8\\[/tex]
Step-by-step explanation:
Since d is the number of large drinks, and there is always a constant of 1 large popcorn, we go to (0, 8). This concludes that since we start off with the cost of 8 dollars with no large drink but a large popcorn, the popcorn will stay a constant cost of $8. (the equation for this scenario is as shown):
y = md + 8
y (total cost)
m (coefficient - in this sense the cost of the drinks.)
d (amount of drinks)
8 (the constant of 8 represents the cost of one large popcorn consistently)
Now, lets find the cost of the dink.
Go to (1, 12).
$12 dollars is the total cost, with one drink and one large popcorn bought.
We have already discussed that we will have a constant of 8 because no matter the amount of drinks we will get, we would have bought 1 large popcorn at $8.
Therefore, we must subtract 8 dollars from 12.
12 - 8 = 4
From the total cost of everything we bought (2 things) and subtracting it with the cost one of the things we bought, we get the cost of the other thing.
each drink will cost $4.
Therefore, with all the variables and their listed meanings, this will be our given equation:
y = 4d + 8

The Panther I traveled approximately 2413 miles before reaching a speed of 130 mph.
What is a trapezoid?A trapezoid is a quadrilateral having two parallel bases and one set of other sides called legs.
To estimate the distance traveled by the Panther I, we need to approximate the area under the velocity curve between 0 and 25.7 seconds. We can divide the area into trapezoids using the data given in the table.
The first trapezoid has a height of 30 mph and a base of 1.8 seconds. The second trapezoid has a height of 40 mph and a base of 1.3 seconds (the difference between 3.1 and 1.8).
Continuing in this way, we get the following table:
Speed Height
Range (mph) Base (s) Area (mph * s)
0-30 30 1.8 54
30-40 40 1.3 52
40-50 50 1.1 55
50-60 60 1.3 78
60-70 70 1.9 133
70-80 80 1.8 144

90-100 100 3.1 310
100-120 120 6.3 756
120-130 130 4.8 624
To find the total area, we add up the areas of all the trapezoids:
54 + 52 + 55 + 78 + 133 + 144 + 207 + 310 + 756 + 624 = 2413
