Answer: The median of the date you gave would be -71. Hope that helps!
Answers: Shasta increases the amount she saves each month by 5%. The amount of cell phone subscribers in a small town increases by 75% each year.The price of a stock goes up 12% each year.
Exponential growth consistently raises the base amount/number to a certain degree. The above answers increase a digit by a number of percentage steadily over a period of time.
Find the area of both first. The sidewalk is 12 * 12 = 144 ft^2, and grass is 10 * 10 = 100 ft^2. Subtract the area of the grass from the sidewalk, 144-100 = 44 ft^2.
If you use this equation then you say that the ground is h=0 and solve as a quadratic.
The quadratic formula is (-b±<span>√(b^2-4ac))/2a when an equation is in the form ax^2 + bx + c
So the equation you have been given would be -16t^2-15t-151 = 0
This equation has no real roots which leads me to believe it is incorrect.
This is probably where your difficulty is coming from, it's a mistake.
The equation is formed from S=ut+(1/2)at^2+(So) where (So) is the initial height and S is the height that you want to find.
In this case you want S = 0.
If the initial height is +151 and the initial velocity and acceleration are downwards (negative) and the initial velocity (u) is -15 and the initial acceleration is -32 then you get the equation S=-15t-16t^2+151
Solving this using the quadratic formula gives you t = 2.64 or t = -3.58
Obviously -3.58s can't be the answer so you're left with 2.64 seconds.
Hope this makes sense.
