Answer:
Option 1
Step-by-step explanation:
Perpendicular lines form right angles
Eliminate Options 3 and 4.Parallel lines never intersect.
Eliminate Option 2.find the intrest for Rs. 10,000 for 2 ½ yrs at 5% per annum compounded annually.
Answer:
Interest = Rs. 1297.26
Step-by-step explanation:
To calculate the final amount, we can use the following formula:
[tex]\boxed{A = P(1 + \frac{r}{100})^n}[/tex],
where:
A = final amount
P = principal (initial) amount
r = rate
n = time in years,
and then we can subtract the initial amount from the final amount to find the interest.
We have been told in the question that the principal, P = Rs. 10,000; and the time is [tex]2\frac{1}{2}[/tex] years, therefore n = 2.5. The rate is 5%, therefore r = 5.
Using this information, and the formula above, we can calculate the final amount:
[tex]A = 10000(1 + \frac{5}{100})^{2.5}[/tex]
⇒ [tex]A = 10000(1.05)^{2.5}[/tex]
⇒ [tex]A = \bf 11297.26[/tex]
Now that we know what the final amount was, we can calculate the interest by subtracting the initial amount from it:
Interest = 11297.26 - 10000
= 1297.26
Therefore the interest was Rs. 1297.26.
On a number line, point A is at 5, and point B is at -10. Point C is on AB such that the ratio of AC to CB is 1: 3. Find D on BC such that the ratio of BD to DC is 3:5.
The location of point D on the number line is -5.15625
How to determine the location of point D?The given parameters are:
A = 5
B = -10
AC : CB = 1 : 3
This means that
C = AC/(AC + AB) * (A - B)
This gives
C = 1/4 * (5 + 10)
Evaluate
C = 3.75
Also, we have:
BD : DC = 3 : 5
So, we have:
D = BD/(BD + DC) * (B - C)
This gives
D = 3/8 * (-10 - 3.75)
Evaluate
D = -5.15625
Hence, the location of point D on the number line is -5.15625

the angle of elevation to the top of a very tall building is found to be 11° from the ground at a distance of 1 mi from the base of the building. using this information, find the height of the building. (round your answer to the nearest foot.)
The height of the building = 1026.328ft
Given the angle of elevation = 11°
The angle of elevation is the angle formed between the horizontal distance to the base of the building and the line of sight to the top of the building.
We know that tan x = opposite side/adjacent side.
Here the opposite side gives the height of the building and the adjacent side is the distance to the base of the building on the ground.
Distance to the base of the building on the ground = 1 mile = 5280 ft.
So tan 11° = h/5280
⇒ h= tan 11° x 5280 = 0.194 x 5280 = 1026.328 ft
So the height of the building = 1026.328 ft

14. Equation Editor Ryan downloaded a video
game to his computer. The size of the file
was 2.4 x 10 (5 th power) kilobytes. After the game was
installed, he downloaded a patch file for the
game that was 48,000 kilobytes in size.
(Lesson 6)
A. What is the size of the game in standard
form?
B. how many times larger was the game than the patch file
Part a: The size of the game in standard form is 240000 kilobytes
Part b: The game was 5 times larger than the patch file
Part A:
Size of the game downloaded by Ryan on his computer = 2.4 * 10^5
Size of the patch file for the game = 48000 kilobytes
Therefore, converting the size of the game into the standard form:
Size of the game = 2.4 * 10^5
= 2.4 * 100000
= 240000 kilobytes
Therefore, the size of the game is 240000 kilobytes in standard form
Part B:
Size of the game = 240000 kilobytes
Size of the patch file = 48000 kilobytes
Computing the size of the game with respect to the patch file we get:
=240000/48000
= 5
Hence, the game was 5 times larger than the patch file

What is rounded numbers?A rounded number is less precise but roughly equal to the original number in value.
To the closest hundred, 341 is equivalent to 300. This is due to the fact that 341 is more similar in value to 300 than to 400. Because $1.89 is closer to $2.00 than to $1.00, when rounded off to the nearest dollar, it becomes $2.00.
The standard rounding rule is as follows:
Round up if the number you are rounding is followed by a 5, 6, 7, 8, or 9. For instance, 38 rounded up to the nearest ten is 40.Round down if the number you are rounding is followed by a 0, 1, 2, 3, or 4. Example: 30 when 33 is rounded to the nearest ten.Learn more about rounded number

for a given non-zero vector v in r 3 there is a unique unit vector parallel to it. is it true or false? explain your answer.
The given statement is true that for a given non-zero vector v in r³ there is a unique unit vector parallel to it.
A vector is defined by its length and direction. If two vectors have the same direction, they are parallel. The length is irrelevant.If the length of a vector is one, it is a unit vector. The direction is irrelevant.So, in order to locate a unit vector parallel to another vector, it must point in the same direction and be of length 1.For a given non-zero vector, there are an infinite number of parallel vectors to it but with different magnitudes. There is only one vector which is not only parallel to the given non-zero vector but also has a magnitude of 1, i.e., the unit vector parallel to it.Thus, it is true that for a given non-zero vector v in r³ there is a unique unit vector parallel to it.To learn more about vectors, visit :

Given,
Juan rolls a fair regular octahedral die marked with the numbers 1 through 8.
Then Amal rolls a fair six-sided die.
Here we need to find the probability that the product of the two rolls is a multiple of 3.
We know that,
On both dice, only the faces with the numbers 3,6 are divisible by 3.
Let
P(a) = 2/8
P(a) = 1/4
it is the probability that Juan rolls a 3 or a 6,
and Similarly,
P(b) = 2/6
P(b) = 1/3

what are the two major advantages of experimental research over correlational studies? multiple select question. experiments are more efficient. causal relationships can be inferred. random assignment is possible. sample size is always greater in experiments.
The experimental research has two key advantages over correlational studies.
1. The possibility of random assignment
2. Causal connections can be assumed.
What benefit does experimental research have over correlational research?Correlational studies merely examine the data that already exists, whereas experimental studies give the researcher the opportunity to influence the study's factors. Researchers can make inferences about how changes in one variable affect changes in another through the use of experimental investigations.
The factors in a correlation study are out of the control of the researcher or research team. The researcher merely measures the information she discovers in the outside world. She can then determine whether changes in one are related to changes in the other, or if the two variables are correlated. In such a study, experimenters gather existing data and use statistical methods to examine it, such as economic statistics from governments. The findings of correlation studies can lead to hypotheses that can be verified through a more focused experimental one.
