The table shows the number of free throws a player makes in a basketball game and the number of points the player scores in the

game. Number of Free Throws vs. Number of Points Scored Number of Free Throws Made (f) Number of Points Scored (s) 5 15 3 11 8 20 7 18 9 21 Alex used a regression calculator to find the equation of the trend line y = a x + b for the data in the table. He rounded the values for a and b on his calculator as shown below. a = 1.7. b = 6.2 Which trend line compares the data in the table? s = 1.7 f + 6.2 s = 6.2 f + 1.7 f = 1.7 s + 6.2 f = 6.2 s + 1.7

Given data in that table forms the 2x3 matrix shown below 2 7 6 5 4 5 a 3-point field goal is worth 3 points a normal field goal is worth 2 points a free throw is worth 1 points.

Answer:

A

Step-by-step explanation:

this is because the amount of points he scores is equal to 1.7 times the free-throws he makes + 6.2, so our equation in slope intercept form is s = 1.7f + 6.2

The point C(2,3) is translated along a vector that is parallel to the line y=3x-2. The translation vector has magnitude square r
qaws [65]

Step-by-step explanation:

The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x

(parallel to y = 3x - 2, slope = 3).

We have x² + (3x)² = 10,

=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.

When x = 1, y = 3. When x = -1, y = -3.

Therefore 2 possible translation vectors

are (1, 3) or (-1, -3).

First new C' = (2 + (1), 3 + (3)) = (3, 6).

Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).

The possible images are (3, 6) and (1, 0).

Answer: second option y = 2(x + 7/2)^2 + 1/2

Explanation:

1) given:

y = (x + 3)^2 + (x + 4)^2

2) expand the binomials:

y = x^2 + 6x + 9 + x^2 + 8x + 16

3) add like terms:

y = 2x^2 + 14x + 25

4) take common factor 2 of the first two terms:

y = 2 (x^2 + 7x) + 25

5) complete squares for x^2 + 7x

x^2 + 7x = [x +(7/2)x ]^2 - 49/4

6) substitue x^2 + 7x = (x + 7/2)^2 - 49/4 in the equation for y:

y = 2 [ (x + 7/2)^2  - 49/4] + 25

7) take -49/4 out of the square brackets.

y = 2 (x + 7/2)^2 - 49/2 + 25

8) add like terms:

y = 2(x + 7/2)^2 + 1/2

And that is the vertex for of the given expression.
