Sarah has received £ 294
<u><em>Solution:</em></u>
Given that £980 is divided between Caroline, Sarah & Gavyn
Let "c" be the amount received by caroline
Let "s" be the amount received by sarah
Let "g" be the amount received by gavyn
<em><u>Caroline gets twice as much as Sarah</u></em>
amount received by caroline = twice as much as Sarah
amount received by caroline = 2(amount received by sarah)
c = 2s ---- eqn 1
<em><u>Sarah gets three times as much as Gavyn</u></em>
amount received by sarah = three times as much as Gavyn
amount received by sarah = 3(amount received by gavyn)
s = 3g ------- eqn 2
Given that total amount is 980
c + s + g = 980 --- eqn 3
<em><u>Let us solve eqn 1, 2, 3 to get values of "c" "s" "g"</u></em>
From eqn 2,
--- eqn 4
Substitute eqn 1 and eqn 4 in eqn 3
Thus sarah has received £ 294
Answer:
Therefore, the standard for will be:
Step-by-step explanation:
The equation of a parabola written as vertical axes is given by:
(1)
The vertex of the parabola (h,k) is (2,-5).
The focus (h,k+p) is (2,-4)
Then we can find p knowing that:
h = 2
k = -5
k + p = -4 then p = -4+5 = 1
Putting all these values in equation (1) we will find the equation of the parabola:
(2)
Now, we need to find the standard form of the equation of the parabola.
Let's recall that standard form is:
We just need to work out equation (2) to convert it to the standard form.
Therefore, the standard for will be:
