Question 23 1 pts
The function
1() = 0.468² - 199s +.264
relates the length
(6)
of a skid mark measured in feet at an accident scene to the
speed
(s)
of the car in miles per hour. That means an accident
reconstructionist can measure the length of a skid mark and
find the speed the car was traveling. If a skid mark with a
length of 82.5 ft was found, find the speed of the car. Round
your answer to the nearest tenth.
a 圍
The car was traveling (a) mph.

Find the zeros of each function. f(x) = 6x^2 - 7x - 20

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.

If 7x=9y, y/z = 7/5 , then x/z = (a) 2/7 (b) 7/9 (c) 9/5 (d) 9/7 (e) 5/9
