Answer:
4
9/8
Step-by-step explanation:
Given the fraction a/b, the reciprocal is expressed as 1/(a/b) = b/a
For 1/4;
1/4
= 1÷1/4
= 1 * 4/1
= 4
Hence the reciprocal is 4
b) 8/9
= 1 ÷ 8/9
= 1 * 9/8
= 9/8
Hence the reciprocal of 8/9 is 9/8
The zeroes of the equation are (1,4)
Step-by-step explanation:
Given equation is:
We have to put y=0 in the equation to find zeroes of the equation
Hence,
The zeroes of the equation are (1,4)

Answer:
75
Step-by-step explanation:
(71+89+100+x)/3=83.75
(83.75*4)
335-100-89-71=75
First of all, I'm going to assume that we have a concave down parabola, because the stream of water is subjected to gravity.
If we need the vertex to be at , the equation will contain a term.
If we start with we have a parabola, concave down, with vertex at and a maximum of 0.
So, if we add 7, we will translate the function vertically up 7 units, so that the new maximum will be
We have
Now we only have to fix the fact that this parabola doesn't land at , because our parabola is too "narrow". We can work on that by multiplying the squared parenthesis by a certain coefficient: we want
such that:
Plugging these values gets us
As you can see in the attached figure, the parabola we get satisfies all the requests.
A: 100 cm³
This is because the others can be multiplied by something 3 times to get it, but A can not.
