Which of the following is the closest approximation to 30−−√?
Responses
5.00
5.25
5.50
5.75
Answers
The closest approximation of the square root of √30 is 5.50.
Square root:
The square root of a number is the inverse operation of squaring a number.
There are four methods to find the square root of numbers and those methods are as follows:
Repeated Subtraction Method of Square RootSquare Root by Prime Factorization MethodSquare Root by Estimation MethodSquare Root by Long Division MethodGiven,
√30
Here we need to find the closest approximation.
Now, we have to use the long division method in order to solve it.
In a long division method, we have to divide large numbers into steps or parts, breaking the division problem into a sequence of easier steps.
So, the square root of 30 is illustrated by the following diagram.
Now, the value of
=> √30 = 5.477
So, the closest approximation is 5.50.

Write the equation of the line that passes through the given point and is perpendicular to the given line. (0, 3); 3x − 4y = −8
Answers
Answer:
y = -4/3x + 3
Step-by-step explanation:
3x − 4y = −8
-4y = -3x - 8
y = 3/4x + 2
slope m = 3/4
perpendicular version of it is opposite inverse: -4/3
y-intercept through point (0, 3):
y = mx + b
3 = -4/3(0) + b
b = 3
Use the perpendicular slope with b from above to form new perpendicular equation of line:
y = mx + b
y = -4/3x + 3
In the figure below, m L 1 = (x + 48)° and m 2 = 2x°.
Find the angle measures.
Answers
Answer:
∠ 1 = 62° , ∠ 2 = 28°
Step-by-step explanation:
angles 1 and 2 form a right angle = 90° , that is
∠ 1 + ∠ 2 = 90 ( substitute values )
x + 48 + 2x = 90
3x + 48 = 90 ( subtract 48 from both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Then
∠ 1 = x + 48 = 14 + 48 = 62°
∠ 2 = 2x = 2 × 14 = 28°
Write the explicit formula for the sequence below and use it to find the 47th term:
-3, 5, 13, 21, . . .
Answers
Given:
The sequence is:
\(-3,5,13,21...\)
To find:
The explicit formula for the given sequence then find the 47th term.
Solution:
We have,
\(-3,5,13,21...\)
The difference between two consecutive terms are:
\(5-(-3)=8\)
\(13-5=8\)
\(21-13=8\)
The given sequence has a common difference. So, the given sequence is an arithmetic sequence with first term -3 and common difference 8.
The explicit formula for an arithmetic sequence is:
\(a_n=a+(n-1)d\)
Where, a is the first term and d is the common difference.
Putting \(a=-3\) and \(d=8\) in the above formula, we get
\(a_n=-3+(n-1)8\)
\(a_n=-3+8n-8\)
\(a_n=8n-11\)
Putting \(n=47\), we get
\(a_{47}=8(47)-11\)
\(a_{47}=376-11\)
\(a_{47}=365\)
Therefore, the explicit formula for the given sequence is \(a_n=8n-11\) and the 47th term is 365.

Answers
The probability that the train will be there when Alex arrives is 0.1.
Given that the time that train arrives between 1:00 P.M to 2:00 P.M. and waits for 10 minutes. Alex arrives between 1:00 P.M to 2:00 P.M.
We are required to find the probability that the train when Alex arrives.
Probability is the likeliness of happening an event among all the events that are possible to happen.
Probability=Number of items/total number of items.
Number of combinations of timings in which the train may have arrived=60/10=6 combinations
Number of ways in which Alex arrives at the station=60.
Probability=6/60
=1/10
=0.1
Hence the probability that the train will be there when Alex arrives ie 0.1.
Question is incomplete. The following things should be included:
Timing in which train arrives is between 1:00 P.M and 2:00 P.M.The train waits for 10 minutes. Alex arrives between 1:00 P.M and 2:00 P.M.

you are sitting in classroom next to the wall looking at the blackboard at the front of the room. the blackboard is 11 ft long and starts 5 ft from the wall you are sitting next to. show that your viewing angle is α
Answers
Your viewing angle α is approximately 46.34 degrees when sitting in the classroom next to the wall and looking at the blackboard.
To show that your viewing angle α is determined by the length of the blackboard and its distance from the wall, we can use geometry and trigonometry.
Let's consider a right triangle formed by your line of sight, the distance from the wall to the blackboard, and the length of the blackboard.
The adjacent side of the triangle is the distance from the wall to the blackboard, which is 5 ft. The opposite side is half the length of the blackboard since you are looking at the midpoint of the blackboard. Therefore, the opposite side is (11 ft)/2 = 5.5 ft.
We can use the tangent function to calculate the viewing angle α:
tan(α) = opposite/adjacent
tan(α) = (5.5 ft)/(5 ft)
tan(α) = 1.1
To find α, take the arctan (inverse tangent) of both sides:
α = arctan(1.1)
Using a calculator, we find that α ≈ 46.34 degrees.
Therefore, your viewing angle α is approximately 46.34 degrees when sitting in the classroom next to the wall and looking at the blackboard.
