Answer 1

Answer: the correct answer is C

Answer 2

Answer: The correct one is C because you want to add the imaginary numbers together to simplify the equation. 6i+5/2i=17/2i. Then you add that to your real number. 17/2i+2/3

The table below gives the list price and the number of bids received for five randomly selected items sold through online auctions. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the number of bids an item will receive based on the list price. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

Which ordered pair is a solution of the equation? y=-2x+5y=−2x+5 (Choice A) A Only (2,-9)(2,−9) (Choice B) B Only (-2,9)(−2,9) (Choice C) C Both (2,-9)(2,−9) and (-2,9)(−2,9) (Choice D) D Neither

Answers

Answer:

Choice B: Only (-2, 9)

Step-by-step explanation:

Of the two choices, only the point (-2, 9) satisfies the equation:

... y = -2x +5

... 9 = -2(-2) +5 = 4 +5 = 9

Answer:

The correct answer is B. Only (-2,9) is a solution of the equation.

Step-by-step explanation:

To figure out if an ordered pair is a solution to an equation, you could perform a test.

Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

We have the equation

$y=-2x+5$

and two different ordered pairs (2, -9) and (-2, 9).

We use the x-value in the first ordered pair, x = 2, and we plug it into the equation.

$y=-2(2)+5\ny=-4+5\ny=1$

If we compare with the ordered pair (2, -9), y must be equal to -9, but when we plugged x = 2 into the equation, we obtained that y = 1, so this is not a solution.

Using the x-value of the second ordered pair, x = -2, we get

$y=-2(-2)+5\ny=4+5\ny=9$

Because we obtained y = 9, when we plugged x = -2, the ordered pair (-2, 9) is a solution of the equation.

The correct answer is B. Only (-2,9) is a solution of the equation.

Will give 100 points to anyone who can find the arc measure and show work! thanks!

Answers

Answer:

2π/3 radians

----------------------

Given:

Arc length (s) = 8π/3
Radius (r) = 4 km

To find the arc measure (θ) in radians, we can use the formula:

s = rθ

Now, plug in the given values:

8π/3 = 4θ

To solve for θ, divide both sides by 4:

(8π/3) / 4 = θ

Simplify the expression:

2π/3 = θ

So, the arc measure (θ) is 2π/3 radians
