The path of a golf ball can be modeled by the quadratic equation y=-0.001x^2+0.3x, where y represents the vertical distance and

x represents the horizontal distance that the ball has traveled in yards. How far does the ball travel before it hits the ground?

Well if y represents the vertical distance of the ball then you want to solve the equation for when y is 0, since 0 would represent the ball being on the ground.  So substitute 0 in for y and solve the equation.

0 = - 0.001x^2 + 0.3x

we have a common factor of x in both terms so we can take that out.

0 = x(-0.001x + 0.3)

Zero product property tells us that we can set both of those products equal to zero and solve

0 = x
0 = -0.001x + 0.3

our first answer is x = 0 is obvious bc thats when the ball starts before you hit it, means it traveled 0.

solving the second equation gives us x = 300 

so the ball traveled 300 "yards" I suppose your problem starts, which is impossible, but no matter thats the answer :-)

It is 8 <br> kilometers from Lucy's house to the nearest mailbox. How far is it in meters?
kirza4 [7]

The prefix 'kilo' stands for 'one thousand'. So, 1 km = 1000m

This obviously implies that 8km is the same as 8000m

Which is the best estimate of the area of a triangle that has the base of 23.62 cm and height of 8.33 cm?
Alexxx [7]

Best estimate of the area of a triangle = 100 \text {cm}^2.

Solution:

Given base of the triangle = 23.62 cm

Height of the triangle = 8.33 cm

Area of the triangle = \frac{1}{2} \times \text{base}\times \text {height}

                                =\frac{1}{2}\times23.62\times 8.33

                                =\frac{1}{2}\times196.7546

                                =98.3773 \ \text {cm}^2

Area of the triangle = 98.3773 \text {cm}^2

Estimation means rounded off to the closest correct answer.

98.3773 rounded off to 100.

Hence, best estimate of the area of a triangle = 100 \text {cm}^2.
