A skydiver is planning her jump out of an airplane. Typically, she will jump at a height of 13,500 feet, and she will pull the cord when she is 5000 feet above the ground. If the equation for the distance traveled during freefall is given as d(t)=16t2 , how long should she wait before pulling the cord?
Answers
Skydiver should wait 23.04 sec before pulling the cord, after freefall.
what is freefall?
An item that is falling only due to gravity is said to be in free fall. Any item that is merely subject to the effects of gravity is referred to as being in free fall.Air resistance does not exist for falling objects in free fall.On Earth, all falling objects experience a downward acceleration of 9.8 m/s/s (commonly represented as 10 m/s/s in quick calculations).Height of jump = 13500ft
Height from which cord will be pulled = 5000ft
Freefall, d=13500-5000 =8500ft
Distance traveled during freefall, d=16t²
substituting values, we get,
8500=16t²
t=23.04 sec
Skydiver should wait 23.04 sec before pulling the cord, after freefall.

Rebecca Sweet was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 806 points. The number of two-point field goals that Rebecca made was 52 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 28 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Rebecca Sweet made during the 2006 regular season.
Answers
In the year 2006, the number of free throws is 100, number of 2 point field goals 128 and the number of 3 point field goals 90.
Let x = number of free throws
y = number of 2 point field goals
z = number of 3 point field goals
However given that Rebecca has a total of 806 points,
Thus x + 2y + 3z = 806 ---------- equation 1
Number of 2 point field goals that Rebecca made was 52 less than double the number of three-point field goals she made ;
thus y = 2z - 52 ---------------- equation 2
Number of 3 point field goals that Rebecca made was 28 less than the number of two-point field goals she made ;
thus x = y - 28 ------------------ equation 3
Thus on solving these three above mentioned equations :
we get x = 2z - 52 -28 [ substituting values in eq 3 from eq 2]
x = 2z - 80 ------------- equation 5
So equation 1 becomes ; 2z - 80 + 2y + 3z = 806
5z + 2y = 886 -------------- equation 4
Thus on solving equation 4 and 2 we get
2 X equation 2 = 4z - 2y = 104
5z + 2y = 886
= 11 z = 990
thus z = 90 and so y = 4 × 90 - 104 = 2y
y= 360 - 104 / 2
= 256/2 = 128
thus y = 128 .
And x= 2z -80 from equation 5 ; x = 180 - 80 = 100 .

The equation is 15 + 0.5x = 25 + 0.25x and number of miles is 40.
While writing the equation for green and blue cars, one time fee will be added with cost of driving for miles. Let us assume the number of miles to be x.
Firstly writing the equation for green car -
Cost = 15 + 0.5×x
Now writing the equation for blue car -
Cost = 25 + 0.25×x
The number of miles for same cost will be calculated by equating the expressions.
15 + 0.5x = 25 + 0.25x
0.5x - 0.25x = 25 - 15
Performing subtraction on Left Hand Side and Right Hand Side of the equation
0.25x = 10
Shifting 0.25 to Right Hand Side of the equation
x = 10 ÷ 0.25
Performing division on Right Hand Side of the equation
x = 40
So, if both the cars travel 40 miles, the rental cost will be same. The correct equation for calculation is 15 + 0.5x = 25 + 0.25x.

A (2,-4), B (3, 3) and C (-1,5) are the vertices of ΔABC . Find the equation of the altitude of the triangle through C.
Answers
Answer:
x + 7y = 34
Step-by-step explanation:
the altitude through C meets the opposite side AB at right angles
calculate the slope of AB using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A (2, - 4 ) and (x₂, y₂ ) = B (3, 3 )
[tex]m_{AB}[/tex] = [tex]\frac{3-(-4)}{3-2}[/tex] = [tex]\frac{3+4}{1}[/tex] = [tex]\frac{7}{1}[/tex] = 7
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{7}[/tex] , then
y = - [tex]\frac{1}{7}[/tex] x + c ← partial equation of the altitude
to find c substitute C (- 1, 5 ) into the partial equation
5 = [tex]\frac{1}{7}[/tex] + c ⇒ c = 5 - [tex]\frac{1}{7}[/tex] = [tex]\frac{35}{7}[/tex] - [tex]\frac{1}{7}[/tex] = [tex]\frac{34}{7}[/tex]
y = - [tex]\frac{1}{7}[/tex] x + [tex]\frac{34}{7}[/tex] ( multiply through by 7 )
7y = - x + 34 ( add x to both sides )
x + 7y = 34 ← equation of altitude in standard form

Answers
The length is 780 feet and the width is 430 feet.
Distance is measured in length.
The dimension of distance is a property of length in the International System of Quantities.
The majority of measurement systems have a base unit for length from which all other units are derived. The meter is the primary unit of length in the International System of Units (SI) system.The term "length" is usually considered to refer to an object's longest dimension.Nevertheless, depending on the position of the object, this isn't always the case.There are several terms used to describe the length of a fixed object, including height, which is also known as vertical length or vertical extension, and width, breadth, or depth.Let the length be x
Width = x - 350
Perimeter = 2260 feet
Now : 2(x + x +350) = 2260
or, 2 x + 700 = 2260
or, 2x = 1560
or, x = 780 feet
So length is 780 feet
Width = 780 -350 = 430 feet
Therefore the length is 780 feet and the width is 430 feet.

Write and solve an inequality which can be used to determine x, the number of people who can go to the amusement park.
Answers
Inequality is 32.50x + $10.50 ≤ $160 and 4 people can go to the amusement park.
What is an inequality?inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
Given that,
$160 = Amount of money they have
$10.50 = Parking Cost
$32.50 = Cost of tickets per person
Because they only have $160, they can't spend more than that amount.
Therefore, the inequality would be the ticket cost per person, times the amount of people being payed for (x) plus the parking cost is less than or equal to the amount of money they have to spend. Hence the inequality:
32.50x + $10.50 ≤ $160
Solve the equation
$160 - $10.50 = $149.50 (149.50 is how much is left for tickets after subtracting the parking cost)
$32.50 x 4 = $130 (4 tickets can be bought for the price of $32.50)
$149.50 - $130 = $19.50 (19.50 isn't enough for another person)
So, the solution to the inequality is 4 people can go to the amusement park.

I’m failing geometry pls help. Why did my teacher mark me wrong on this problem and what are the correct answers?
Answers
Step-by-step explanation:
it is a bit difficult to read the handwriting (and even the printed original texts) in this diffuse picture.
let's go through the 3 problems as I could decipher them.
1)
from what I can see you made a calculation mistake for y.
but you were right with your approaches.
12x - 8 = 15x - 23
15 = 3x
x = 5
therefore,
12x - 8 = 12×5 - 8 = 60 - 8 = 52°
and the large angle up there is
52 + 70 = 122°
and now
6y + 96 = (12x - 8) + 70 = 122
6y = 26
y = 26/6 = 13/3
by the way, x and y are not angles (and degrees). they are just factors in the expressions to calculate some angles.
12, 15 and 6 are not ° either. all are calculation factors or terms, that then together define the ° of angles.
2)
you made a mistake with the identification of what angles the linear pair is.
3x = 5x - 20
20 = 2x
x = 10 (again, not °, just a number)
3x = 3×10 = 30° (this is then an angle)
= 5x - 20
for y we could then use 2 different approaches
a) your linear pair approach.
4y is one angle, true, but the other is (2y + 3x) !
so,
4y + 2y + 30 = 180
6y = 150
y = 25 (again, not °, just a number)
2y = 50°
4y = 100°
3)
I hope you are right with (11x + 19) and (12y - 24). I would have read this in the picture as (11x + 18). and it could be (12y + 24).
assuming you are right :
11x + 19 = 7x + 47
4x = 28
x = 7 (again, not °, just a number)
11x + 19 = 7x + 47 = 96°
7z + 17 = 87
7z = 70
z = 10 (again, not °, just a number)
and yes, for y we are using the linear pair again. the two combining angles are (12y - 24) and (11x + 19).
(12y - 24) + (11x + 19) = 12y - 24 + 96 = 180
12y + 72 = 180
12y = 108
y = 9 (again, not °, just a number)
12y - 24 = 12×9 - 24 = 108 - 24 = 84°

A solution set exists the set of values that satisfy a given set of equations or inequalities.

What is a solution set of an equation?A solution set exists the set of values that satisfy a given set of equations or inequalities. For instance, for a set of polynomials over a ring , the solution set exists the subset of on which the polynomials all vanish (evaluate to 0), formally.
The formula,
h = 16t²
where h is height and t is time.
You want to see how long it will take an object to fall 1600 feet down to the ground. These means its position must be 1600.
By setting the equation equal to this value,
we get:
1600 = 16t²
To estimate the value of t.
First, divide both side by 16, getting:
100 = t²
Now taking the square root of both sides, we get:
√(100) = 10 seconds.
