1. the athletes were either running or jumping. if the ratio of the number of runners to the number of jumpers was 9 to 5 and 2170 were observed, how many were jumpers? 2. sam found that if the product of 5 and a number is increased by 8, the result is 10 more than the product of 3 and the number. what is the number? 3. if g(x) = -4 x^2 - 3, find g(-3) 4. solve for y: 3x + 4y = 8 -y

For the given quadratic equation convert into vertex form, find the vertex and find the value for x=6 y=-2x^2+2x+2

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
