A student claims that the rectangular point below can be represented by the
Sladkaya [172]

Since we don't have a figure we'll assume one of them is right and we're just being asked to check if they're the same number.  I like writing polar coordinates with a P in front to remind me.

It's surely false if that's really a 3π/7; I'll guess that's a typo that's really 3π/4.

P(6√2, 7π/4) = ( 6√2 cos 7π/4, 6√2 sin 7π/4 )

P(-6√2, 3π/4) = ( -6√2 cos 3π/4, -6√2 sin 3π/4 )

That's true since when we add pi to an angle it negates both the sine and the cosine,

cos(7π/4) = cos(π + 3π/4) = -cos(3π/4)

sin(7π/4) = sin(π + 3π/4) = -sin(3π/4)

Answer: TRUE

If 3x − (7 − x) = 29, find the value of 6x.
Stells [14]

Answer:

54

Step-by-step explanation:

3x -(7-x) = 29       remove the parens

3x - 7 + x = 29     simplify

4x -7 = 29            add 7 to both sides of the equation

4x = 36            divide by

x = 9

then 6x = 6 * 9 = 54

Riley wants to predict a soccer team's number of wins. She considers the number of goals scored by the team's top scorer during
Phoenix [80]

Answer:

b) y=1/3x+5

Step-by-step explanation:

Without the actual scatter plot we would need to deduce from the options provided which would closely model the data. Since the number of goals scored in a game can only be 0 or positives then we can remove options a) and c) since a value of x = 0 would output a negative value to y. That leaves us with options b) and d). Since we know that soccer games vary in the number of goals then we can remove option d) since it represents a steady trend line of 4. Finally, we are left with option b) as the answer.

Which expressions are equivalent to 4^−2 ⋅7 ^-2?
Andrews [41]

Answer:

We can have several equivalents.

It can be 1/784,  28^(-2),  or  1/ (28^2)

Step-by-step explanation:

4^(-2) * 7^(-2) =  (4*7)^(-2) = 28^(-2)

or  1 / (28^2)   is another equivalent.

4^(-2) * 7^(-2) = 28^(-2)

4^(-2) * 7^(-2) = = 1/784
