The ball may rise up to a height of 20 feet. and it will strike the ground in 1 second.
Describe height.Height is the vertical measurement from an object's top to its base. On sometimes, it has the designation "altitude."
The vertex at point (h,k) of a parabola, y = ax2 + bx + c, is first determined using the equation h = -b / 2a, and then that point is entered into the equation to determine k.
Let's now solve for h in this issue. We know that a = -16, b = 32, and c = 4 in the equation y = -16t2 + 32t + 4.
h = -b/2a
h = -(32) / 2(-16) (-16)
1 second is equal to h = -32/-32.
This means the the ball will reach it's maximum height after 1 seconds. But the problem is asking is for what that height is. So for our final step, let's plug in t=1 to our equation:
y = -16t^2 + 32t + 4
y = -16*(1)^2 + 32*(1)+ 4
y = -16 + 36
y = 20 feet
which means that the final answer is that the maximum height of the ball is 20 feet. and it will take 1sec to hit the ground.

17. Geometry The figure shown is a rectangle. The green shape in the figure is a square. The blue anc white shapes are rectangles, and the area of the blue rectangle is 24 square inches.
a. Write an expression for the area of the entire figure that includes an exponent. Then find the area.
b. Find the dimensions of the entire figure.
The expression for the area that includes an exponent is 6² + (6 × 2) + 24
Area of the entire figure is 72 square inches
The dimension of the entire figure is 9 inches by 8 inches
Calculating the area of a figureFrom the question, we are to write an expression for the area of the entire figure
Area of the entire figure = Area of green shape + Area of white shape + Area of blue shape
Area of the entire figure = 6² + (6 × 2) + 24 square inches
The expression is 6² + (6 × 2) + 24
Thus,
Evaluating
Area of the entire figure = 6² + (6 × 2) + 24
Area of the entire figure = 36 + 12 + 24
Area of the entire figure = 72 square inches
b. The dimension of the entire figure
Width of the entire figure = Length of the green square + Width of the white rectangle
Width of the entire figure = 6 inches + 2 inches
Width of the entire figure = 8 inches
Then,
Length of the entire figure = Length of the white rectangle + Width of the blue rectangle
First, we will determine the width of the blue rectangle
Using the formula,
Area = l × w
Where l is the length
and w is the width
24 = (2 + 6) × w
24 = 8 × w
w = 24/8
w = 3 inches
Therefore,
Length of the entire figure = 6 inches + 3 inches
Length of the entire figure = 9 inches
Hence, the dimension is 9 inches by 8 inches

Step-by-step explanation:
Find the equation of the rational function f whose graph satisfies the conditions horizontal asymptote is y=0 vertical asymptote is x=-3 and contains the point (0,1)
A function assigns the values. The function is f(x) = (8x - 8)/(x² + 2x).
What is a Function?A function transfers each element's value from one set to a particular element in another set.
There is a denominator and a numerator in a rational function.
The x-values that the function approaches but never reaches are known as vertical asymptotes. We can get the vertical asymptotes by setting the denominator to zero.
Since x=-2 and x=0 are the vertical asymptotes, our function's denominator will be x(x+2) = x2+2x.
Y values that the function approaches but never reaches are known as horizontal asymptotes. The degree of the numerator must be less than the degree of the denominator since the horizontal asymptote is y=0. Our numerator will be x - 1 because the x-intercept is equal to 1.
At this time, One can assume that the function is f(x) = (x - 1)/(x2+2x).
Next, we must apply the f(2)=1 condition. If we enter x=2, f(x) ought to be equal to 1. However, we must multiply the function's right side by a constant called C.
Then, the constraint f(2)=1 must be used. F(x) should be equal to 1 if we substitute x=2. The right side of the function must be multiplied by a constant C, though.
1 = C(2 - 1)/(2²+2(2))
Solve for C.
1 = C / 8\s8 = C
Consequently, the equation will be f(x) = [8(x - 1)] / [(x2 + 2x)].
f(x) = (8x - 8) / (x² + 2x)
Thus, f(x) = (8x - 8)/(x2 + 2x) is the function.

Define similarity.When it comes to Euclidean geometry, two things are said to be similar if they have the same shape or the same shape as each other's mirror image. One can be created from the other more precisely by evenly scaling, possibly with the inclusion of further translation, rotation, and reflection. If two figures have the same shape, they are said to be comparable. In more formal terms, two figures are said to be comparable if their respective angles are congruent and their corresponding side length ratios are identical. The scale factor is the name given to this usual ratio.

Using the Weshcler IQ test, adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 15. b) Find the score of an individual who is at the 85th percentile.
The 85th percentile of a normal distribution is the score that is greater than or equal to 85% of the scores in the distribution. This means that the score at the 85th percentile is the same as the score that would be earned by the top 15% of individuals in the distribution.
To find the score at the 85th percentile, we can use the standard normal distribution table or use a calculator to find the z-score corresponding to the 85th percentile. The z-score is the number of standard deviations that a score is above or below the mean of the distribution.
Using a calculator or table, we find that the z-score corresponding to the 85th percentile is 1.04. Since the mean of the distribution is 100 and the standard deviation is 15, this means that the score at the 85th percentile is 100 + (1.04 * 15) = 120.4.
Therefore, the score of an individual who is at the 85th percentile on the Weshcler IQ test is 120.4.

How many reflections symmetries does a decagon shaped like a five- pointed star have? How many rotational symmetries does the decagon have? Draw the reflection symmetries on the decagon.
Decagon has a total of 5 reflection symmetries
A reflection symmetry of a shape is a line that divides the shape into two halves that are mirror images of each other. To find the number of reflection symmetries of the decagon, we can draw lines through the center of the decagon that pass through pairs of opposite vertices.
We can draw a total of 5 lines through the center of the decagon that pass through pairs of opposite vertices. Each of these lines is a reflection symmetry of the decagon. Therefore, the decagon has a total of 5 reflection symmetries.
A rotational symmetry of a shape is a rotation about a fixed point that leaves the shape unchanged.
To find the number of rotational symmetries of the decagon, we can count the number of times we can rotate the decagon about its center by 36 degrees (which is the central angle of the decagon) and obtain the same shape. In this case, we can rotate the decagon about its center by 36 degrees 10 times and obtain the same shape each time.
A decagon shaped like a five-pointed star has 10 sides and 5 vertices, and it looks like this:

A = dir(108);
B = dir(72);
C = dir(36);

E = dir(-36);
F = dir(-72);
G = dir(-108);

Drag each object to show whether cost is proportional to area in the situation represented.
Increasing the area from 400 to 600 (50%) results in an increase in cost from 500 to 750 (50% increase), which shows that the cost is not proportional to the area.
In a situation where cost is proportional to area, the relationship between cost and area is said to be directly proportional. Direct proportionality means that if the value of one variable (in this case, area) is multiplied by a certain factor, then the other variable (in this case, cost) will also be multiplied by the same factor. The mathematical formula for direct proportionality is [tex]y = kx,[/tex] where y and x are the two variables, and k is the constant of proportionality. If the relationship between the variables is not proportional, then it is a non-proportional relationship.
The objects are proportional if increasing one quantity by a certain factor results in the other quantity increasing by the same factor. In this case, cost is proportional to area if doubling the area would double the cost. Based on the table, we can see that the cost is not proportional to the area since the cost does not increase by the same factor as the area. For example, increasing the area from 400 to 800 (double) results in an increase in cost from 500 to 1000 (also double). However, increasing the area from 400 to 600 (50%) results in an increase in cost from 500 to 750 (50% increase), which shows that the cost is not proportional to the area.
