Four students are trying to find the rule that translates point N(–2, –4) to N prime (2, 4). Each student’s reasoning is shown b

elow. Raheem: The rule is (x times (negative 1), y times (negative 1)) because Negative 2 times (negative 1) = 2 and Negative 4 times (negative 1) = 4. Casey: The rule is (x 2, y 4) because the image is (2, 4). Andrew: The rule is (x 4, y 0) because the coordinates are opposites. Lo: The rule is (x 4, y 8) because Negative 2 4 = 2 and Negative 4 8 = 4. Which student is correct? Raheem Casey Andrew Lo.

Four students are trying to find the rule that translates point N (–2, –4) to N prime (2, 4),

According to Lo's statement : The rule is (x + 4, y + 8) because Negative 2 + 4 = 2 and Negative 4 + 8 = 4.

The answer of Lo is Correct By applying the rule (x+4, y+8) on the coordinates N(-2, -4) will give us N'(2,4)

<h3>How do find whose statement is correct?</h3>

To find that we need to first understand students' statements accordingly.

Given: Student statements as:-

  • Raheem: The rule is (x times (negative 1), y times (negative 1)) because Negative 2 times (negative 1) = 2 and Negative 4 times (negative 1) = 4.

  • Casey: The rule is (x + 2, y + 4) because the image is (2, 4).

  • Andrew: The rule is (x + 4, y + 0) because the coordinates are opposites.

  • Lo: The rule is (x + 4, y + 8) because Negative 2 + 4 = 2 and Negative 4 + 8 = 4.

Now let's understand all the statements of respective students,

According to Raheem, his statement is incorrect because it states that we can only use addition or subtraction and not multiplication in transitions.

Therefore, Raheem's answer is NOT CORRECT.

According to Casey, his statement is incorrect because after applying the rule : (x+2, y+4) on the coordinates N(-2, -4) that will give (0,0) but not N'(2,4).

Therefore, Casey's answer is NOT CORRECT.

According to Andrew, his statement is incorrect because after applying the rule: (x+4, y+0) on the coordinates N(-2, -4) that will give us (2,-4) but not N'(2,4).

Therefore, Andrew's answer is NOT CORRECT.

According to Lo, his statement is correct because after applying the rule: (x+4, y+8) on the coordinates N(-2, -4) that will give us N'(2,4).

Therefore, Andrew's answer is CORRECT.

Hence, The answer of Lo is Correct By applying the rule (x+4, y+8) on the coordinates N(-2, -4) will give us N'(2,4)

Alrighty

we gots 1/4 circle and paralellogram

area circle=pi times radius^2
area paralelogram=base times height


1/4 circle is
radius is 10 so
area part circle is 1/4 times pi times 10^2=100/4pi=25pi=78.5 m²

area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30

30+78.5=108.5 m² is the area

A movie studio surveyed married couples about the types of movies they prefer. In the survey, the husband and wife were each ask
Aleksandr [31]

Using proportions, it is found that out of the next 75 couples asked, 49 will have at least one spouse that prefers action movies.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Researching this problem on the internet, it is found that out of 150 couples initially surveyed, 26 + 25 + 12 + 22 + 13 = 98 couples had at least one spouse preferring action movies, hence the proportion is:

p = 98/150 = 0.6533.

Out of the next 75 couples, the amount is:

A = 0.6533 x 75 = 49

Hence, out of the next 75 couples asked, 49 will have at least one spouse that prefers action movies.

Paul received a 12,000 loan from the bank. The bank charges his 6.99% yearly interest rate. 4 years, how much money does Paul ow
andre [41]
Principal amount = 12,000
Annual interest rate (r) = 6.99% = 0.0699
Time (years) = 4 years
Number of installments (t) = 12*4 = 48 months

Monthly payment, A = P/D

Where,
D= {(1+r/12)^t-1}/{r/12*(1+r/12)^t} = {(1+0.0699/12)^48-1}/{0.0699/12(1+0.0699/12)^48} = 42.47

Therefore, A = 12000/42.47 = 282.59

Total payments after 4 years = 282.59*4*12 = 13,564.17

Interest owed = 13,564.17 - 12,000 = 1,564.17
