Answer:

  • largest: R
  • smallest: K

Step-by-step explanation:

The slope of the graph at x=0 is related to the value of b. It is also proportional to the value of <em>a</em>, which is the same for all but curve B. The red curve R has the largest slope at x=0, (much larger than 3/4 the slope of curve B), so curve R has the greatest value of <em>b</em>.

Similarly, the smallest value of <em>b</em> will correspond to the curve with the smallest (most negative) slope. That would be curve K. Curve K has the smallest value of <em>b</em>.

A basketball coach collected data to analyze the free throw shooting percentages of players during a game and during practice. T
Dima020 [189]

Answer: The correct answer is option A; 78

Step-by-step explanation: The equation representing the line of best fit which is given as

y = 0.9x - 1

depicts the relationship between a player's practice results and actual game results. Whatever value is given as x which is the result from practice would be a good way of predicting a player's result when engaged in the real game.

For the question above, a player with  a practice shooting percentage of 88 would have his game shooting estimated by simply inserting the value of his practice percentage into the equation showing the line of best fit shown as follows;

y = 0.9x - 1

Where x = 88

y = 0.9 (88) - 1

y = 79.2 - 1

y = 78.2

y ≈ 78

Therefore the approximate shooting percentage for a player with a practice shooting percentage of 88 would be 78 percent.

Answer:

The Center is (-2 , 3)
Radius of the circle is 3

Step-by-step explanation:

x^{2}  + 4x + y^{2} - 6y = -4\\(x + 2)^{2}  + (y - 3)^{2}  = 9

∴ the center is ( -2, 3)

radius of thw circle is 3
