Answer:
a. a = 1.83 m/s²
b. a = 0 m/s²
c. Average Velocity = 9.09 m/s
d. a = - 0.33 m/s²
Step-by-step explanation:
a.
We apply 1st equation of motion to the first 6 seconds of the motion:
Vf = Vi + at
a = (Vf - Vi)/t
where,
a = acceleration during first 6 seconds = ?
Vf = Final Speed = 11 m/s
Vi = Initial Speed = 0 m/s
t = time = 6 s
Therefore,
a = (11 m/s - 0 m/s)/6 s
a = 1.83 m/s²
b.
From 6 s to 8 s Sean held his speed constant at 11 m/s. Since, the speed was constant. Therefore, there is no acceleration during this time:
a = 0 m/s²
c.
Sean's average velocity can be found as follows:
Average Velocity = Total Distance Covered/Total Time
Average Velocity = 100 m/11 s
Average Velocity = 9.09 m/s
d.
Applying the 2st equation of motion for last 3 s from 8s to 11 s:
Vf = Vi + at
a = (Vf - Vi)/t
where,
Vf = 10 m/s
Vi = 11 m/s
t = 3 s
Therefore,
a = (10 m/s - 11 m/s)/3 s
a = - 0.33 m/s²
negative sign shows deceleration

ground floor. It goes up 7
floors and then down 9 floors.
What floor is it on?
Answer:
Two floors underground
Step-by-step explanation:
Answer:
-2nd level, in the basement
Step-by-step explanation:
If we look at the number line, we can track the movement of the elevator. The ground floor is point 0. The blue dot indicates the starting position. The blue arrow indicates the positive movement of 7, and the red arrow shows negative movement of 9. The red dot is the elevator's final position.

Which best represents the solution set of all real numbers?
[ [ PLEASE ANSWER , I'M CONFUSED ] ]
Answer:
B.
Step-by-step explanation:
Since the solution set is all real numbers, our solution graph must cover the entire number line.
We can see that B contains the graph that extends infinitely in both directions, thereby covering the entire number line.
Therefore, our answer is B.
A is not correct because it leaves out [-6, 1] (approximately).
C is not correct because it leaves out everything to the left of -7 and everything to the right of 1.

Write down in terms of n, an expression for the nth term of the following sequences: a) 1 8 15 22 29 B) 12 16 20 24 28
A)
Sequence: 1 , 8 , 15 , 22 , 29
Difference : 7
Back one : -6
Expression : 7n-6
B)
Sequence: 12 , 16 , 20 , 24 , 28
Difference : 4
Back one : 8
Expression : 4n+8
A sequence is an ordered list of elements with a specific pattern.
The nth term of the sequence:
A) 1 8 15 22 29 is [tex](n-1)^{th}[/tex] + 7.
B) 12 16 20 24 28 is [tex](n-1)^{th}[/tex] + 4.
What is a sequence?A sequence is an ordered list of elements with a specific pattern.
Example: 2, 5, 8, 11, ... is a sequence where each term is obtained by adding 3 to its previous term.
We have,
a) 1 8 15 22 29
1 + 7 = 8
8 + 7 = 15
15 + 7 = 22
22 + 7 = 29
We see that each term is obtained by adding 7 to the previous term
So, the nth will be in the form:
nth = [tex](n-1)^{th}[/tex] + 7
b) 12 16 20 24 28
12 + 4 = 16
16 + 4 = 20
20 + 4 = 24
2 + 4 = 28
We see that each term is obtained by adding 4 to the previous term.
So, the nth term will be in the form:
nth = [tex](n-1)^{th}[/tex] + 4
Thus the nth term of the sequence:
1 8 15 22 29 is [tex](n-1)^{th}[/tex] + 7.
12 16 20 24 28 is [tex](n-1)^{th}[/tex] + 4.

Step-by-step explanation:
Solve 2x + 5 = 12
what’s the what is x
Answer:
x = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
Given
2x + 5 = 12 ( subtract 5 from both sides )
2x = 7 ( divide both sides by 2 )
x = [tex]\frac{7}{2}[/tex] [ or x = 3.5 ]

The customer must first pay an annual 300 a ductile in the policy covers 70% of cost of x-rays the first Insurance claim for Pacific year submitted by a person or two X-Rays the first x-ray cost 6:40 and the secondary x-ray cost 950 how much in total will he need to pay for these x-rays
Answer:
$177
Step-by-step explanation:
Given that:
Percentage covered by policy = 70%
Hence, person needs to pay (100 - 70)% = 30%
X - Ray cost :
1st = 640
2nd = 950
Total cost = (640 + 950) = 1590
Amount the person has to pay:
Total cost * 30%
1590 * 0.3 = $477
Since the person has $300 deductible :
$477 - $300 = $177

In sailing, it is not possible to head straight into the wind. In order to get upwind, a sailboat simply sails at an angle to the wind and then turns to sail back toward where it wants to go. Assume that a boat needs to get directly upwind 6000 m. If it sails off at a 45 degree angle to the wind and then turns back 90 degrees towards the original goal, how far would it have to sail to get directly upwind 6000 meters? Round to the nearest tenth.
Distance to get directly upwind 6000 meters: ____________________ meters

4242.6
8485.3
10392.3
Answer:
C. 8485.3 meters
Step-by-step explanation:
Think of the sailboat’s path as a 45-45-90 right triangle.
The hypotenuse is the 6000 meter distance.
In this way the leg will be the hypotenuse divided by √2.
So 6000/√2 or 4242.64 meters.
Remember that the sailboat has to turn and head back toward its goal and travel another 4242.64 meters.
Thus, your answer is 4242.64 x 2 = 8485.28 meters or 8485.3 meters.
In this exercise we have to use the knowledge of triangles to calculate the distance that one of the sides has:
Letter C
Some information given in the statement about the triangle:
Sailboat’s path as a 45-45-90 right triangle.The hypotenuse is the 6000 meter distance.So performing the calculation we have:
[tex]6000\sqrt{2}=4242.64 \\4242.64 * 2 = 8485.28[/tex]

Enter the equation in slope-intercept form. Then graph the line described by the equation.
5x + y = 1
Slope-intercept form is (select)
5x +y = 1
Answer:
y = 1 -5x
Step-by-step explanation:
You have to get y by itself. So first you move 5x to the other side but since it’s positive you have to make it negative so it canceled out.
Hi there!
[tex]\large\boxed{y = -5x + 1}[/tex]
5x + y = 1
Arrange into slope-intercept form (y = mx + b):
Subtract both sides by -5x to isolate y:
5x - 5x + y = 1 - 5x
y = 1 - 5x
Rearrange:
y = -5x + 1
Graph the equation by finding corresponding x and y values:
