Find the tangential and normal components of the acceleration vector:
r(t)=ti+t2j+8tk
At= ? An=?
The tangential component of the acceleration is At=0 and the normal component of the acceleration is An=2j.
To find the tangential and normal components of the acceleration vector, we first need to find the velocity and acceleration vectors.
The velocity vector is the derivative of the position vector:
r(t) = ti + t^2j + 8tk
v(t) = r'(t) = i + 2tj + 8k
The acceleration vector is the derivative of the velocity vector:
a(t) = v'(t) = 2j
The acceleration vector is constant and is directed entirely in the y-direction, so the tangential component of the acceleration is zero.
The normal component of the acceleration is the magnitude of the acceleration vector, which is:
|a| = √(0^2 + 2^2 + 0^2) = 2

B. 1417 termites
Step-by-step explanation:
Rosanne and Jimmy are looking to purchase a house. They found one that they like, but the inspection report showed that there was a problem. The foundation has termites. The report states that the foundation of a house has 1200 termites. The termites grow at a rate of about 2.4% each day.
A. Formulate an equation in exponential form that represents the termite situation.
The formula for exponential growth or increase =
P(t) = Po (1 + r)^t
Where:
P(t) = Population growth after time t
P(o) = Initial Population = 1200 termites
r = Growth rate = 2.4% = 0.024
t = Time in days
Hence, the equation in exponential form that represents the termite situation is given as:
P(t) = 1200( 1 + 0.024)^t
B. The extermination is scheduled out for one week from the date of the report. Use your equation to determine how many termites will be in the home at the time of the extermination.
The time of extermination = 1 week
1 week = 7 days
Hence,
t = 7 days
P(t) = Po (1 + r)^t
P(7) = 1200( 1 + 0.024)⁷
P(7) = 1200(1.024)⁷
P(7) = 1416.7099449 termites

The construction engineer has a maximum of 6400 man-hours of labor for the construction. Let your variables be the number of units of house B and the number of units of house C to be constructed. a) Write an inequality which states that there are 8000 sq. m. of land available. b) A unit of house B requires 160 man-hour and a unit of house C requires 256 man-hour.

Answer:
Step-by-step explanation:
4x is in a multiplication form
4x=36
meaning a number when multiplied with 4 gives the answer 36
hence in order to find the answer
36 divided by 4 which is equivalent to 9
answer is 9
Answer: \(x = 9\)
Step-by-step explanation:
We must isolate \(x\) on one side of the equation in order to solve the equation \(4x = 36\) for \(x\).
Step 1: Divide both sides of equation by 4:
\(\frac{4x}{4} = \frac{36}{4}\)
Step 2: Simplify
\(x = 9\)

The difference between the park and house of a student is 1Km 575m. Every day he walks both ways between the park and his house. Find the total distance covered by him in a week's time?
The student covers a total distance of 22.05 kilometers in a week's time, walking between the park and the house each day.
To find the total distance covered by the student in a week's time, we need to calculate the distance covered in one round trip (from the house to the park and back) and then multiply it by the number of round trips in a week.
Given that the difference between the park and house is 1 kilometer and 575 meters, we can convert it to a total distance of 1.575 kilometers.
In a round trip, the student covers twice the distance between the park and the house, which is 1.575 kilometers * 2 = 3.15 kilometers.
Now, we need to determine how many round trips the student makes in a week. Let's assume the student makes one round trip each day.
Since there are 7 days in a week, the total distance covered by the student in a week's time is 3.15 kilometers * 7 = 22.05 kilometers.

The exam scores for 200 students are normally distributed with a mean of 72 and a standard deviation of 10. Which answer choice below represents the number of students with scores between 72 and 82?.
Using the normal distribution, it is found that there are 68 students with scores between 72 and 82.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
\(\mu = 72, \sigma = 10\)
The proportion of students with scores between 72 and 82 is the p-value of Z when X = 82 subtracted by the p-value of Z when X = 72.
X = 82:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{82 - 72}{10}\)
Z = 1
Z = 1 has a p-value of 0.84.
X = 72:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{72 - 72}{10}\)
Z = 0
Z = 0 has a p-value of 0.5.
0.84 - 0.5 = 0.34.

According to the statement
we have given that the a identity and we have to use in the given conditions.
So, For this purpose, we know that the
Given that the required identity of Tangent is Tangent (x + y) = (tangent (x) + tangent (y))/(1 - tangent(x) × tangent (y)),
we have:
tan(x + y) = sin(x + y)/(cos(x + y))
sin(x + y)/(cos(x + y)) = (Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y) - sin(x)·sin(y))
(Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y) - sin(x)·sin(y)) = (Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y))/(cos(x)·cos(y) - sin(x)·sin(y))/(cos(x)·cos(y))
(Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y))/(cos(x)·cos(y) - sin(x)·sin(y))/(cos(x)·cos(y)) = (tan(x) + tan(y))(1 - tan(x)·tan(y)

A) Horizontal or vertical reflection.
B) Horizontal or vertical stretch.
C) Horizontal or vertical shift
D) Reflection across the line y=x
The function g(x) is a transformation of the parent function f(x) it was transformed to make g(x) - Horizontal or vertical stretch.
What is Horizontal or vertical stretch?Let's start thinking about vertical stretching and compression by simply looking at the graphs rather than starting with a ton of math.
Vertical stretching is the process of making a function taller by stretching it out vertically.
Vertical compression entails squashing the function down vertically, making it shorter.
Stretching and compression genuinely appear like that. It's time to start doing some math to figure out how to modify the function so that the graph can be stretched or compressed.
When the function that generated the original graph is changed in a way that necessitates a smaller x-value in order to get the same y-value, this is known as horizontal compression.
This happens when a constant c with a value larger than 1 is multiplied by the x-value of a function.
Hence, The function g(x) is a transformation of the parent function f(x) it was transformed to make g(x) - Horizontal or vertical stretch.

Given that Arccos (√3/2)=β, what are all the angle measurements for right triangle ABC?
Answer:
30°, 60° and 90°
Step-by-step explanation:
Given the expression Arccos (√3/2)=β, we can use the expression to calculate one of the acute angles in a right angled triangle.
Note that a right angled triangle is made up of two acute angles and a right angled (90°)
Let's get one of the acute angles first
If Arccos (√3/2)=β
β = cos^-1 √3/2
β = 30°
This shows that one of the acute angles is 30°
To get the third angle, we know that sum of angles in a triangle is 180° and since we already know two of the angles, i.e 90° and 30°, we can get the third angle.
90+30+x = 180
120+x = 180
x = 180-120
x = 60°
All the angle measurement for the right angled triangle are 30°, 60° and 90°

Elevation of the cable car 14 minutes after it begins descending from the top of the hill= 105 meters from the ground
Step-by-step explanation:
Given the elevation, e(x) in meters, of a cable car from the ground , x minutes after it begins descending from the top of a hill.
e(x)=840-52.5x
e(14)=840-52.5(14)
