Step-by-step explanation:
Neglecting air resistance, the distance h(t) in feet traveled by a freely falling object is given by the function , where t is time in seconds. The height of a certain tower is 912 feet. How long would it take an object to fall to the ground from the top of the building? Round to nearest 0.1 second
Answer:
t = 7.54 seconds
Step-by-step explanation:
The distance h(t) in feet traveled by a freely falling object is given by the function :
[tex]h(t)=16t^2[/tex]
The height of a tower is 912 feet.
It is required to find the time it will taken to fall on ground from the top of the building. It can be calculated as :
[tex]16t^2=912\\\\t=\sqrt{\dfrac{912}{16}}\\\\t=7.54\ s[/tex]
So it will taken 7.54 seconds to fall on the ground.

Prosta aa i prosta bb są do siebie prostopadłe, a także prosta bb i prosta cc są do siebie prostopadłe. Wybierz poprawne uzupełnienie zdania. Prosta aa jest prostopadła / równoległa do prostej cc.
Answer:
- In a 3-D setting, straight line aa can be perpendicular or parallel to straight line cc.
- In a 2-D setting, straight line aa can only be parallel to straight line cc.
- W ustawieniu trójwymiarowym linia prosta aa może być prostopadła lub równoległa do linii prostej cc.
- W ustawieniu 2-D linia prosta aa może być równoległa do linii prostej cc.
Step-by-step explanation:
English Translation
Straight line aa and straight line bb are perpendicular to each other, as well as straight line bb and straight line cc are perpendicular to each other. Choose the correct completion of the sentence. Line aa is perpendicular / parallel to line cc.
Solution
If the frame of reference for the lines is in 3-D, then, it is the straight line aa can also be perpendicular to the straight line cc in the same vein as the x, y and z component lines are usually all perpendicular to one another. Note that straight line aa could also be parallel to straight line cc in a 3-D frame of reference.
But in a 2-D frame of reference, straight line aa can only be parallel to straight line cc. This is because the only directions that straight line bb can be perpendicular to, in a 2-D setting, are all in the same parallel direction.
In Polish/Po polsku
Jeśli układ odniesienia dla linii jest w 3-D, to jest to linia prosta aa może być również prostopadła do linii prostej cc w tej samej żyle, ponieważ linie składowe x, y i z są zwykle wszystkie prostopadłe do jednego inne. Należy zauważyć, że linia prosta aa może być również równoległa do linii prostej cc w trójwymiarowym układzie odniesienia.
Ale w dwuwymiarowym układzie odniesienia linia prosta aa może być tylko równoległa do linii prostej cc. Jest tak, ponieważ jedyne kierunki, w których prosta bb może być prostopadła, w ustawieniu 2-D, wszystkie są w tym samym kierunku równoległym.

Answer:3,969[tex]^{2}[/tex](squared) or 63
Step-by-step explanation:
First you must plug the answers into the equation A[tex]^{2}[/tex] + B[tex]^{2}[/tex]=C[tex]^{2}[/tex]
Then you square the numbers. example: 2[tex]^{2}[/tex]=2 x 2=4
After that you subtract from both sides of the equation to get the variable by itself. Example: 4+b[tex]^{2}[/tex]=10
-4 -4
b[tex]^{2}[/tex]=10
After that you square both sides or you could say answer[tex]^{2}[/tex]
Ali made $126 for 9 hours of work. At the same rate, how many hours would he have to work to make $168 ?
Answer:
12 hours
Step-by-step explanation:
First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.
Let's set that up into a fraction so it's easier to look at.
money/time = 126/9
Now that we have that set up let's look at our other piece of information.
It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.
In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.
126/9 = 14.
This means that for every 1 hour, there will be 14 dollars earned.
Now that we know that, let's look for how many hours it take to earn $168.
In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.
168/14 = 12 hours.

The Magic Carpet charges $90 for installation and $9 per square yard of carpeting. The Carpeteria's installation price is $50 but the store charges $13 for each square yard. For what number of square yards of carpeting will the cost, including installation, be the same for both stores? 6a) What expression that represents the cost of having Magic Carpet install carpeting: 6b) What expression that represents the cost of having Carpeteria install carpeting: 6c) Write an algebraic equation that represents when the cost of installing carpet by the two companies will be the same: 6d) For what number of square yards of carpeting will the cost, including installation, be the same for both stores? Solve the equation in 1c. Show your work.
Answer:
The cost of the carpet at Magic Carpet is: 90 + 9*(area of carpet)
The cost of carpet at Carpeteria is: 50 + 13*(area of carpet)
The algebraic expression for which the cost is the same is: 90 + 9*(area of carpet) = 50 + 13*(area of carpet)
The area of carpet for which the cost is the same is: 10 square yard
Step-by-step explanation:
6a) The cost for magic carpet:
This company charges a fixed fee and a price for each square yard of carpeting, therfore the expression for the cost is:
cost = 90 + 9*a
Where a is the area of carpet to be installed.
6)b) The cost for Capeteria:
This company also charges a fixed fee and a price for each square yard of carpeting, so the expression is:
cost = 50 + 13*a.
6) c) The algebraic expression for the cost to be the same in both stores:
90 + 9*a = 50 + 13*a
6) d) We need to solve the expression above for a:
50 + 13*a = 90 + 9*a
13*a - 9*a = 90 - 50
4*a = 40
a = 40/4 = 10

An anthropologist visits an igloo with a circular floor. While there, she measures it and calculates that it has a circumference of 18.84 yards. What is the floor's diameter?
Answer:
The diameter of the floor is 6 yards
Step-by-step explanation:
Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards
Mathematically,
C = π * D
where C is the circumference
Plugging the values of the circumference , we have ;
18.84 = 22/7 * D
7 * 18.84 = 22D
D = (7* 18.84)/22 = 5.99 which is approximately 6 yards

A rhombus has side lengths of 25. What could be the lengths of the diagonals? *
Answer:
0 < x < 50
Step-by-step explanation:
We start out with a square (which IS a rhombus for all sides are equal in
length. That's when the diagonals are equal in length, which, by the
Pythagorean theorem equal to
5*√2
C^2=a^2+b^2
=25^2+25^2
Factorise
c^2=25^2 × 2
c=square root of 25^2 × 2
That is
c=√25^2 × 2
=5×√2
As we decrease the angle on the bottom left and increase the angle on
the bottom right, the green diagonal increases to 25+25 or 50, but never gets to 50. The red diagonal shrinks to 0 but never gets to 0.
the lengths of a diagonal can only be in the open interval from 0 to 50. In interval notation that is (0,50) or 0 < x < 50.
Answer:
Minimum value: 0, Maximum value: 50
Step-by-step explanation:
A rhombus is a quadrilateral with side of same length but different angle pairs. Let consider the following rhombus (See attachment). It is known that sum of all angles in quadrilateral is equal to 360°. The length of each diagonal is, respectively:
[tex]d_{1} = 2\cdot l\cdot \sin 0.5\alpha[/tex]
[tex]d_{2} = 2\cdot l \cdot \sin (90-0.5\alpha)[/tex]
[tex]d_{2} = 2\cdot l \cdot (\sin 90^{\circ}\cdot \cos 0.5\alpha - \cos 90 \cdot \sin 0.5\alpha)[/tex]
[tex]d_{2} = 2\cdot l \cdot \cos 0.5\alpha[/tex]
Each expression shows that value of a diagonal changes at the expense of the other one inasmuch angle changes. The minimum and maximum values of any of the diagonal occur when trigonometric functions are equal to 0 and 1, respectively.
Minimum value: [tex]d_{min} = 0[/tex], Maximum value: [tex]d_{max} = 2\cdot l = 2 \cdot (25) = 50[/tex]

What is the probability of the complement of spinning an even number by using the spinner below?
Answer:
Think about a dice. When a dice is rolled there are 6 possible outcomes: 1, 2, 3, 4, 5 and 6. To find the probability of the event of rolling a 4, find the number of possible ways of rolling a 4 and divide it by the total number of possible outcomes.
There is one way of rolling a 4 and there are six possible outcomes, so the probability of rolling a 4 on a dice is . This is called the ‘theoretical probability’ - in theory, if you roll a dice six times then you should roll a 4 once.

What is the slope of the line through (-9,-6)(−9,−6)left parenthesis, minus, 9, comma, minus, 6, right parenthesis and (3,-9)(3,−9)left parenthesis, 3, comma, minus, 9, right parenthesis?
Answer:
[tex]-\dfrac{1}{4}[/tex]
Step-by-step explanation:
Given two points (-9,-6) and (3,-9). The slope of the line through the points is determined by the formula:
[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1} ,$ where (x_1,y_1)=(-9,-6), (x_2,y_2)=(3,-9)\\$Therefore:\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]
The slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]
Answer:
the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]
Step-by-step explanation:
Given that,
Points (x₁ , y₁) is (-9,-6) respectively and
( x₂ , y₂) is (3,-9) respectively.
The slope of the line through the points is determined by the formula:
[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where x₁ = -9
y₁ = -6
x₂ = 3
y₂ = -9
Therefore:
[tex]\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]
Therefore, the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]
