(a) If you fit your data to this function with n set exactly equal to 2, then we have to find v(x, i) is equivalent to -2At(0).
(b) If you fit your data to this function with n set exactly equal to 2, then we have to find v(x, i) is equivalent to At(0)^2+B.
The given equation is x(f) = x(i)+v(x, i)Δt+12a(x)(Δt)^2.
Here x = x(f)-x(i)
So the equation is
x = v(x, i)Δt+12a(x)(Δt)^2..................(1)
The function in the program
x = A(t-t(0))^n+B
(a) If you fit your data to this function with n set exactly equal to 2, then we have to find v(x, i) is equivalent to.
If we set n = 2. Then;
x = A(t-t(0))^2+B..................(2)
On comparing the equation (1) and (2), we get
A = 1/2 a(x)
So, a(x) = 2A
x(f) = At^2+At(0)^2-2Att(0)+B.......................(3)
Now comparing the equation (1) and (3)
v(x, i) = -2At(0)
(b) If you fit your data to this function with n set exactly equal to 2, then we have to find x(i) is equivalent to.
On comparing the equation (2) and (3), we get
x(i) = At(0)^2+B

Complete question is:
Equation 3.8 in the textbook states x(f) = x(i)+v(x, i)Δt+12a(x)(Δt)^2. In this lab you will collect data for the position, x, as a function of time, t. The software you will use will allow you to fit data using a function of the form x=A(t−t(0))^n+B.
1. If you fit your data to this function with n set exactly equal to 2, what is v(x, i) equivalent to?
2. If you fit your data to this function with n set exactly equal to 2, what is x(i) equivalent to?

what is the rate of change of y=0.5•x-2
Answer:
0.5
Step-by-step explanation:
rate of change is just a synonym for slope and the equation for slope is y=mx +b where m is the slope so 0.5=m and if m= slope then 0.5=slope=rate of change :)
Practice Triangle Ratios (Sides) Find the value of c. Round to the nearest tenth!
Answer:
30.6688
Step-by-step explanation:
We usually use the formula SOHCAHTOA meaning Sine = opposite side/hypotenuse Cosine = opposite side /hypotenuse then Tangent = Opposite side/Adjacent side. We then say Tan61°= x/17 to get the height as 30.6688 PS/ Hypotenuse is the slanting side of the triangle

An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all 6 balls drawn from the urn are white? Round your answer to three decimal places.
Answer:
The probability is 0.022
Step-by-step explanation:
Firstly, we need to get the total number of balls in the urn
mathematically, we have this as ;
8 + 9 = 17
now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls
Mathematically, we have this as 9/17
Now, since the event is carried out with replacement, the probability for the six times is the same
So, we have the probability as;
(9/17)^6 = 0.022

The proportional relationship between the distance driven and the amount of time driving is shown in the
following graph.
Which statements about the graph are true ?
A. The y- coordinate of point A represents the distance driven in 4 hours.
B. The distance driven in 1 hour is 80 km
C. None of the above
The distance driven in 1 hour is 80 km. Therefore, option B is the correct answer.
The given time graph shows the proportional relationship between the distance driven and the amount of time driving.
What is a distance-time graph?If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.
From the graph, we can see that object A moved 400 km in 5 hours time.
So, in 1 hour the distance travelled by object =400/5=80 km
Therefore, option B is the correct answer.

In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 to 53 and one number from 1 to 46. A player wins a minimum award of $400 by correctly matching two numbers drawn from the white balls (1 through 53) and matching the number on the gold ball (1 through 46). What is the probability of winning the minimum award?
Answer:
[tex] \frac{10}{53 \times 46 \times 26} [/tex]
Step-by-step explanation:
The probability of matching the number drawn on the gold ball is
[tex] \frac{1}{46} [/tex]
The number of possible pairs of numbers from 1 to 53 is
[tex] \binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26[/tex]
Choosing 5 numbers, you are choosing 10 different pairs:
[tex] \binom{5}{2} = \frac{5 \times 4}{2} = 10[/tex]
Therefore the probability of correctly matching the drawn pair is
[tex] \frac{10}{53 \times 26} [/tex]
Thus, the probability of winning (matching the pair AND the gold ball) is
[tex] \frac{10}{53 \times 46 \times 26} [/tex]

A central angle of a circle of diameter 6 cm measures 86°. What is the length of the intercepted arc?
A)
2.8 cm
B)
4.5 cm
C)
5.1 cm
D)
9 cm
Answer:
B)
4.5 cm
Step-by-step explanation:
The formula for arc length when our central angle is in degrees =
2πr(θ/360)
θ = 86°
Diameter = 6cm Radius = Diameter /2
Radius = 6cm/2 = 3cm
Hence,
Intercepted arc length = 2 × π × 3 (86/360)
= 2 × π × 3 × 0.2388888889
= 4.5029494701 cm
Approximately = 4.5 cm
Option B is the correct answer
Ana participated in a charity walk. She
raised $0.25 for each 1/2
mile that she
walked. The first day, Ana walked 11 miles.
The second day, she walked 14 miles.
How much money did Ana raise?
Answer:
if $0.25 for each mile, then $1.00 =1 mile.
so the first day would be = $1=1mile
$n=11 miles
= 1n= 11×1=$ 11
Step-by-step explanation:
and the 2nd day is = 14×1= $14.
So the answer is 14+11=$25.00
Mario walked 250 ft south then 430 ft west. How far is he from the starting point? Round off answers to the nearest hundredths place.
Answer:
497.39 FEET
Step-by-step explanation:
Please check the attached image for a diagram of the bearings
This question can be solved using Pythagoras theorem

we want to determine the value of c
250² + 430² = 247400
c = √247400 = 497.39 feet
A zoologist studies a population of 800 rabbits. He tags 160 rabbits at random, of which 37 have blue eyes. Based on this data, about how many rabbits in the population have blue eyes?
Answer:
185
Step-by-step explanation:
Population size = 800
Sample size = 160
Number of blue-eyed rabbit in sample = 37
The proportion of blue-eyed rabbit in the sample is :
p = number of blue eyed rabbit / sample size
p = 37 / 160 = 0.23125
Estimated number of blue eyed rabbit in population :
p * population size
0.23125 * 800
= 185

Okay so because the right side is two times the length and width of the left side, we need to divide 20 and 14 by 2 which gives us 10 and 7. That means x+2 = 10 so we need to subtract 2 from each side which gives you 8. Therefore, x = 8.
20/2 = 10
10 - 2 = 8
x = 8
