Answer:
A. horizontal velocity is constant at 25 m/s in every interval
B. downward velocity increases by 9.8 m/s each second, to 19.6 m/s, 29.4 m/s, 39.2 m/s, 49.0 m/s
Step-by-step explanation:
A.Since the ball is not rocket-powered, it has no acceleration in the horizontal direction. (We ignore slowing due to air friction.) The horizontal velocity remains constant at 25 m/s.
__
B.The vertical acceleration is given as 9.8 m/s² in the downward direction. That is, each second the ball is in motion, its velocity downward increases by 9.8 m/s. The table can be filled with ...
t = 2 s, v = -19.6 m/s
t = 3 s, v = -29.4 m/s
t = 4 s, v = -39.2 m/s
t = 5 s, v = -49.0 m/s
__
The sign is negative because the direction is downward. Positive is up.

An atrium is being designed to house an exhibit of tropical birds. The atrium must enclose 250,000 cubic feet of space, and the designer wants it to have the shape of a hemisphere. Is such a design possible given that the plot of land on which it will be built is a rectangle 90 feet wide and 100 feet long?
The proposed design of the atrium (V < V') is possible since its volume is less than the maximum possible atrium.
Can this atrium be built in the rectangular plot of land?
The atrium with the maximum allowable radius (R), in feet, is represented in the image attached. The real atrium is possible if and only if the real radius (r) is less than the maximum allowable radius and therefore, the real volume (V), in cubic feet, must be less than than maximum possible volume (V'), in cubic feet.
First, we calculate the volume occupied by the maximum allowable radius:
V' = (8 · π / 3) · (45 ft)³
V' ≈ 763407.015 ft³
The proposed design of the atrium (V < V') is possible since its volume is less than the maximum possible atrium. [tex]\blacksquare[/tex]

What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following expression -
y = (-1/3)sin(2x)
We have -
y = (-1/3)sin(2x)
We can write -
ωx = 2x

To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $9.80 per hour. The math club wants to spend at most $117.40 on renting the meeting room. What are the possible amounts of time for which they could rent the meeting room? Use t for the number of hours the meeting room is rented, and solve your inequality for t.
Answer:
0 < t ≤ 8 (in hours)
Up to (and including) 8 hours
Step-by-step explanation:
Let t = number of hours the room is rented
Given:
Reservation fee = $39Fee per hour = $9.80Maximum total cost = $117.40Create an equation using the given information and solve for t:
⇒ 39 + 9.8t ≤ 117.4
Subtract 39 from both sides:
⇒ 9.8t ≤ 78.4
Divide both sides by 9.8
⇒ t ≤ 8
Therefore, the possible amounts of time for which they could rent the meeting room is 0 < t ≤ 8 (in hours)
Answer:
8 is the very maximum number of hours the room can be rented. As long as 8 is not exceeded, the room is rentable for what money the math club has.
Step-by-step explanation:
Givens
Maximum payment = 117.40Cost per hour = 9.80Fixed charge = 39 dollarsFormula
payment ≥ 39 + 9.80*t where t is in hours.
Solution
117.40 ≥ 39 + 9.80*t Subtract 39 from both sides.
117.40 - 39 ≥9.80*t
78.40 ≥ 9.80*t Divide by 9.8
78.40/9.80 ≥ 9.80*t/9.80
8 ≥ t
Answer t≥ 8

A garden measuring 8 feet by 12 feet will have a walkway around it. The walkway
has a uniform width, and the area covered by the garden and the walkway is
192 square feet. What is the width of the walkway?
A. 2 feet
B. 3. 5 feet
C. 4 feet
D. 6 feet
By solving a quadratic equation, we will see that the width of the walkway is 3ft.
How to get the width of the walkway?Remember that for a rectangle of length L and width W, the area is:
A = W*L
Now, we know that for our garden we have:
W = 8ft
L = 12ft
If we add a walkway of width x around the garden, then the new measures are:
W' = 8ft + 2x
L' = 12ft + 2x
So the area is:
A' = ( 8ft + 2x)*( 12ft + 2x)
And we know that it is equal to 192 ft^2, then:
192 ft^2 = ( 8ft + 2x)*( 12ft + 2x)
Now we can solve this for x.
192ft^2 = 96ft^2 + 4x^2 + 20ft*x
0 = 96ft^2 - 192ft^2 + 20ft*x + 4x^2
0 = -96ft^2 + 20ft*x + 4x^2
This is a quadratic equation, and the solutions are given by the Bhaskara's formula:
[tex]x = \frac{-20ft \pm \sqrt{(20ft)^2 - 4*4*(-96ft^2)} }{2*4} \\\\x = \frac{-20ft \pm 44ft}{8}[/tex]
We only take the positive solution, so we get:
x = (-20ft + 44ft)/8 = 3ft
So the width of the walkway is 3ft.

to factor consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
the factors are + 3 and - 4 , since

Well, it says Max put $1 on the first day(which is already entered for you), then it says that he put in $2 on the second day. Then it says that he doubles how much he puts in each day after, which just means to multiply the last entered amount by 2. So, he put in 2 x 2 = $4 on the third day, and lastly, 4 x 2 = $8 on the fourth day.

Find an equation for the line that passes through the points (6, -1) and (-6, 2).
Answer:
[tex]D : y = \frac{-1}{4}x + \frac{1}{2}[/tex]
Step-by-step explanation:
let D be the line that passes through the points (6, -1) and (-6, 2)
Then D has an equation of the form D: y = ax + b
Now we need to find a and b in order to be able to write the equation of the line D:
[tex]a = \frac{-1-2}{6-(-6)}= \frac{-3}{12}= \frac{-1}{4}[/tex]
Since the point (6 , -1) lies on the line D then :
-1 = (-1/4) × (6) + b
then
-1 = (-6/4) + b
then
b = -1 - (-6/4) = -1 + 6/4 = -4/6 + 6/4 = (-4+6)/4 = 2/4 = 1/2
then
b = 1/2
Conclusion:
Since a = -1/4 and b = 1/2 then
[tex]D : y = \frac{-1}{4}x + \frac{1}{2}[/tex]
