The quadratic model is given by:
y = ax2 + bx + c
We evaluate three points to find the values of a, b and c.
We have then:
For (0, 200):
200 = a (0) 2 + b (0) + c
c = 200
For (0.5, 195):
195 = a * (0.5) ^ 2 + b * (0.5) +200
195-200 = a * (0.5) ^ 2 + b * (0.5)
-5 = 0.25a + 0.5b
For (1, 185):
185 = a * (1) ^ 2 + b * (1) +200
185-200 = a * (1) ^ 2 + b * (1)
-15 = a + b
Solving the system:
-5 = 0.25a + 0.5b
-15 = a + b
We have the following results:
a = -10
b = -5
Substituting:
y = -10x ^ 2 - 5x + 200
For x = 3 we have:
y = -10 (3) ^ 2 - 5 (3) + 200
y = - 90 - 15 + 200
y = 95
Answer:
the height at 3 seconds is:
y = 95 feet
Answer:
Use an ruler if you must listen to explanation.
Step-by-step explanation:
So this is actually very easy so it already tells you the Width= Feet is 80. But the Length = Feet is 6 greater any time you see something that says Number? Greater it means Multiply so multiply 6x80=480 so your length will be 480 Ok that's true But! The Width isn't answered your paper/screen Says, The perimeter of a rectangular outdoor patio is 80 ft. The length is 6 feet greater than the width what are the dimersions of the patio. Dimersion's what is it? The number.
So your confused?
Here are a list of things you can use,
A ruler
A protractor
Or A Tape Measuerer
Pardon if spelled wrong.
Anyway the perimeter is 80 ft. Here's what i would do i would use a ruler and see how long the width is then times that with 6 and you should get your answer i cannot use my ruler because picture is to small even when clicked this should help you.
Hope this helped!
99.99 - 64.25= 35.74
35.74/64.25= 0.556=55.6% or 56% rounded
Answer:
One side is 9 m
Step-by-step explanation:
Perimeter = 36 m
Perimeter = 4a
a = P/4
a = 36/4
a = 9
