A player shoots a basketball from a height of 6 feet. The equation, h=−16t2+25t+6, gives the height, h, of the basketball after t seconds. Describe the height, rounded to the nearest tenth of a foot, of the basketball after 1.5 seconds, assuming no other player touches the ball. feet above the ground

7.5

Give the values of a, b, and c needed to write the equation's standard form. (5 + x)(5 - x) = 7 A = -1; B = 0; C = 25 A = 1; B = 0; C = -18 A = 25; B = 0; C = -1

A = 1; B = 0; C = -18

Identify the function in standard form. 3x 2 + 6x - 12 = 0 3x 2 + 2x + 10 = 0 5x 2 - 10x + 5 = 0

ANSWER IS NOT 2x 2 - 4x + 6 = 0

ANSWER IS NOT 5

Give the values of a, b, and c needed to write the equation's standard form. A = 1; B = 0; C = 20 A = 1; B = 0; C = -5

ANSWER IS NOT A = 1/4; B = 5; C = 0

Give the values of a, b, and c needed to write the equation's standard form. A = 2; B = 2; C = -43 A = 2/3; B = 1; C = -20

ANSWER IS NOT A = 2; B = 2; C = 43

Choose the equation that best represents the standard form of the following expression. x 2 - 14x = 0 - x 2 + 14x + 0 x 2 - 7x + 2 = 0

ANSWER IS NOT x 2 + 14x = 0

Select all of the following that are quadratic equations. 5 x 2+ 15 x = 0 6 x - 1 = 4 x + 7 x 2 - 4 x = 4 x + 7 2 x - 1 = 0 3 x 2 + 5 x - 7 = 0 x 3 - 2 x 2 + 1 = 0

3 x 2 + 5 x - 7 = 0 5 x 2+ 15 x = 0 x 2 - 4 x = 4 x + 7

A ball is dropped from the top of a building that is 1,000 feet high. Its height, in feet, as a function of the time, x, in seconds, after the ball was dropped, is given by the following equation, ƒ(x) = 1,000 - 16x 2. Which set of numbers is appropriate as the domain for this function? Positive Real Numbers Natural Numbers Positive Rational Numbers

IS NOT Positive Integers
