suppose a tennis player hits a ball over the net. The ball leaves the racket 0,5 m above the ground. The function h= -4.9t^2 + 3.8t +0.5 gives the ball's height, h, in meters after t seconds...

h(t)=-162+40t+80

A rectangular garden measures 24m by 32m. a path of uniform width is built all around the outside of the garden. The total area of the path and garden is 1540m2. Find the width of the path. please...

A gardener has 40m of fencing to make three equal rectangular plots. The total area of the three plots is 30m2. Determine the constraints on the dimensions of the rectangles, and find the dimensions...

how many seconds after the rocket is launched does it reach maximum height? What is maximum height? How long until it hits the ground?

This is for quadratics

This is for quadratics

A ,B and C are integers and 'x€R' means that x is an element of real numbers

The height of a ball at a given time can be modelled with the quadratic function h(t) = -5+20t+1, where height, h(t), is in metres and time, t, is in seconds. How long is the ball in the air...

7x2 - 10x - 1 = 0

Is the highest point (0,4)? How do I create a quadratic function?

The sum of two positive numbers is 62. 1. Write an equation that gives the product of the two numbers

8n2 + 4n - 16 = -n2

Lena is in a cave whose floor measures 20 x 20 m, and is 30 m tall. She wants to determine an equation that describes the path in the air, Her experiment launches to measuring device from the midpoint...

im in high school and I haven’t learned derivetives yet so it would be great if the answer was able to be solved as simple as possible

Harriet jumped off a cliff into the ocean while vacationing with some friends. Her height above the ocean in feet, hh, as a function of time in seconds, t, is given by the function h=−16(t^2−t−30) How...

Write an equation for the family of quadratic functions, in factored form, with the zeros 0 and negative 8.

Quadratic trinomials are obtained when binomial expressions are expanded. Consider the following: (x + a)(x + b) = x2 + bx + ax + ab This means that quadratic...
