Which polar coordinates represent the same point as (4, −π/2)

1 answer:

7 0

You can go full 2π rotate around counterclockwise so the angle wouldn't be negative.

So -π/2 + 2π = -π/2 + 4π/2 = 3π/2

So (4, 3π/2) is the same point as (4, -π/2)

Answer:

y + 5 > -2 i.e. option 4.

Step-by-step explanation:

An inequality is shown in the number line by an arrow and we have to identify the inequality from the options given.

It is clear from the given figure that the y variable is plotted and its value is greater than - 7 but not including - 7.

Therefore, option 4 which gives the inequality y + 5 > -2 will be the correct answer.

As it gives y > - 2 - 5 i.e. y > - 7 (Answer)

Explain how the commutative property of addition,the Associative property of addition and mental math can help you find 75.2+(57

4vir4ik [10]

Answer: The sum of 75.2+(57.376+24.8) is 157.376.

Explanation:

The commutative property of addition states that,

$a+b=b+a$

The associative property of addition states that,

$a+(b+c)=(a+b)+a$

The given expression is 75.2+(57.376+24.8).

First use commutative property of addition in the parenthesis.

$75.2+(57.376+24.8)=75.2+(24.8+57.376)$

Now use associative property of addition.

$75.2+(24.8+57.376)=(75.2+24.8)+57.376$

Now simplify the expression,

$(75.2+24.8)+57.376=100+57.376$

$(75.2+24.8)+57.376=157.376$

Therefore, the sum of 75.2+(57.376+24.8) is 157.376.
