Mariano is standing at the top of a hill when he kicks a soccer ball up into the air. The height of the hill is h feet, and the ball is kicked with an initial velocity of v feet per second. The height of the ball above the bottom of the hill after t seconds is given by the polynomial –16t2 + vt + h. Find the height of the ball after 2 seconds if it was kicked from the top of a 60 foot tall hill at 84 feet per second.
The height of the ball after 2 seconds is 100 feet.
What is the height function?
A height function exists as a function that quantifies the intricacy of mathematical objects. The height of an object, h(t), exists defined by the formula [tex]-16 t^{2}[/tex] + vt + h.
Given: Let, the polynomial equation be [tex]-16 t^{2}[/tex] + vt + h
h = 20 ft and v = 72 ft/s
y = [tex]-16 t^{2}[/tex] + 72t + 20
To estimate the height of the ball after 2 seconds
substitute the value of t = 2, then
y = -16 [tex]\times[/tex] 4 + 72 [tex]\times[/tex] 2 + 20
= -64 + 144 + 20
= 100 feet
The height of the ball after 2 seconds is 100 feet.

Answer and Step-by-step explanation:
In a polygon, when a shape is similar but dilated, the angles are still congruent.
Also, turn the pentagon QRSTP counterclockwise 90 degrees so it is upright and looks like pentagon ABCDE (making it easier to read).
A. The measure of angle P is 124 degrees, as it matches up with angle E.
B. To find the length of side r, we need to find the scale factor. We do this by looking at the given side on pentagon QRSTP (side RS) and match it with its similar side of pentagon ABCDE (side BC)
To find the scale factor, you divide the side of the bigger shape by the side of the smaller shape. For us, this results in the scale factor being 2.
Now, the similar side to r is side ED. We need to divide 7.5 by 2 to find r.
When doing so, we get r to be 3.75.

For about 10 years after the French Revolution, the French government attempted to base measures of time on multiples of ten: One week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100 seconds. What are the ratios of (a) the French decimal week to the standard week and (b) the French decimal second to the standard second
Answer:
[tex](a)\ Ratio = 1.43[/tex]
[tex](b)\ Ratio = 0.864[/tex]
Step-by-step explanation:
Given
[tex]French\ Week= 10\ days[/tex]
[tex]French\ days= 10\ hours[/tex]
[tex]French\ hours= 100\ minutes[/tex]
[tex]French\ minutes= 100\ seconds[/tex]
Solving (a): Ratio of french minute to standard week
This is calculated as:
[tex]Ratio = \frac{French\ week}{Standard\ week}[/tex]
[tex]Ratio = \frac{10\ days}{7\ days}[/tex]
[tex]Ratio = \frac{10}{7}[/tex]
[tex]Ratio = 1.43[/tex]
Solving (b): Ratio of french second to standard second
This is calculated as:
[tex]Ratio = \frac{French\ second}{Standard\ second}[/tex]
Convert french days to seconds
[tex]French\ days= 10\ hours[/tex]
[tex]French\ days = 10hr * 100mins/hr * 100secs/min[/tex]
[tex]French\ days = 10 * 100 * 100secs[/tex]
[tex]French\ days = 100000\ secs[/tex]
This gives:
[tex]French\ second = \frac{1}{100000}day[/tex]
For standard day, we have:
[tex]Standard\ second = \frac{1}{86400}day[/tex]
So, we have:
[tex]Ratio = \frac{1/100000}{1/86400}[/tex]
Rewrite as:
[tex]Ratio = \frac{1}{100000} \div \frac{1}{86400}[/tex]
[tex]Ratio = \frac{1}{100000} * \frac{86400}{1}[/tex]
[tex]Ratio = \frac{86400}{100000}[/tex]
[tex]Ratio = 0.864[/tex]

Find the area of each figure
Answer:
92
Step-by-step explanation:
this figure can be "split" into 3 sub-figures.
one rectangle in the middle, one triangle to the right, and one triangle on top.
these areas we can calculate very easily. and then we simply sum up all 3 of them and we have the answer.
it is clear, the area of a rectangle is length×width.
and the area of triangle is baseline×height/2.
where in a right-angled triangle one of the sides next to the 90 degree angle is the baseline and the other is the height.
the rectangle
R = 10×6 = 60
the triangle to the right
T1 = (14-10)×6/2 = 12
the triangle on the top
T2 = 10×(10-6)/2 = 20
so, the total area is
60+12+20 = 92
The area of the given figure is 92.
This figure contained 3 sub-figures.
One rectangle in the middle, one triangle to the right, and one triangle on top.
The area of these areas we can calculate very easily. and then we ad all 3 of them and we have the answer.
What is the area of a rectangle?The area of a rectangle is,
[tex]A=length\times width.[/tex]
What is the area of triangle?The area of triangle is
[tex]A^*= \frac{1}{2} \times base\times height[/tex]
Where in a right-angled triangle one of the sides next to the 90 degree angle is the baseline and the other is the height.
The area of rectangle
[tex]R =l\times w \\R=10\times 6 \\R= 60[/tex]
The triangle to the right
[tex]T_1 = (14-10)\times 6/2 = 12[/tex]
The triangle on the top
[tex]T_2 = 10\times (10-6)/2 = 20[/tex]
Therefore, the total area is,
60+12+20 = 92
Therefore the area of the given figure is 92.

a. At least one subject
b. Exactly one subject
c. At most one subject
Answer:
a = 118
b = 96
c = 108
Step-by-step explanation:
105 + 25 = 130
130 students
83 = maths ONLY
105 - 83 - 22
22 = maths and science
95 didnt like science
130 - 95 = 35
35 liked science
35 - 22 = 13
13 people liked science ONLY
83 + 22 + 13 = 118
130 - 118 = 12
leaving 12 as the people who like neither
130 - 22 = 108 = people who like 0 or 1 subject (at most one subject)

A shipping container is in the shape of a right rectangular prism with a length of 2 feet, a width of 3 feet, and a height of 5 feet. The container is completely filled with contents that weigh, on average, 0.84 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
13 pounds
Step-by-step explanation:
volume = base area × height
area of a rectangular triangle = a×b/2
Vp = (2×3/2) × 5 = 3×5 = 15 ft³
weight of contents = 15 × 0.84 = 12.6 pounds = 13 pounds rounded.
Point J is on line segment \overline{IK} IK . Given IK=5x,IK=5x, IJ=4,IJ=4, and JK=4x,JK=4x, determine the numerical length of \overline{IK}. IK
Answer:
IK = 20
Step-by-step explanation:
If Point J is on the line segment IK, then;
IK = IJ + JK
Given that
IJ = 4
IK = 5x
JK = 4x
Substitute into the expression
5x = 4 + 4x
5x - 4x = 4
x = 4
Get the value of IK
IK = 5x
IK = 5(4)
IK = 20
Hence the numerical length of IK is 20

The dot plot showed the number of flowers on a rosebush: 18, 18, 18, 18, 20, 20, 22, 23 The number 19 is used to summarize the data. What does this number measure?
Answer:
19 measures the median
Step-by-step explanation:
The dot plot is not shown, but the question can still be answered.
We have:
[tex]Samples: 18, 18, 18, 18, 20, 20, 22, 23[/tex]
[tex]n = 8[/tex]
Calculate the median position using:
[tex]Median = \frac{n + 1}{2}th[/tex]
[tex]Median = \frac{8 + 1}{2}th[/tex]
[tex]Median = \frac{9}{2}th[/tex]
[tex]Median = 4.5th[/tex]
4.5th means the median is the mean of the 4th and 5th item.
We have:
[tex]4th = 18[/tex]
[tex]5th = 20[/tex]
So:
[tex]Median = \frac{18 + 20}{2}[/tex]
[tex]Median = \frac{38}{2}[/tex]
[tex]Median = 19[/tex]
