Solution: The equation is , 2 =3 ×
Out of the given options :
The number 2 is 3 times the size of 2/3.
For example, if and b are any two real numbers, a≠0,∧b≠0 then
→a= b×(a/b).
Or
A/B=k, then A=Bk→A=B×A/B replacing k by A/B.
Answer:
1 2/4
Step-by-step explanation:
3/4 doubled is 
Now, 
on simplification.
Therefore,
3/4 doubled is 1 2/4
The first
thing to do is to find the roots.
The sum of
the roots, x1 + x2 = -b / a
<span>x1 + x2 = 3
/ 2 </span>
The product
of the roots, x1 * x2 = c / a
<span>x1 * x2 = 5 /
2 </span>
The AM means arithmetic mean and is calculated using the
formula:
AM = (x1 + x2) / 2
AM = (3 / 2) / 2
AM = 3 / 4 = y1
The HM means harmonic mean and is calculated using the
formula:
2 / HM = 1 / x1 + 1 / x2
or
2 / HM = (x1 + x2) / x1 * x2
Rewriting in terms of HM alone on the left side:
HM = 2 x1*x2 / (x1 + x2)
HM = 2 (5 / 2) / (3 / 2)
HM = 10 / 3 = y2
Creating an equation from y1 and y2:
(y – ¾) (y – 10/3) = 0
y^2 – 10/3 y – ¾ y + 30/12 = 0
y^2 - 49/12 y + 30/12 = 0 (ANSWER)
or
<span>y^2 – 4.083y + 2.5 = 0</span>
Answer:
The answer is "(0,0)"
Step-by-step explanation:
In the given some information is missing that is point so, the correct answer to this question can be described as follows:
book Number = x
overall Book weight = y
Neither x nor y can be negative. We have to be positive values, then.
Since x indicates the number of books, that must be a positive integer. It can not be a decimal number or fractional number.
So the only viable solution from the given options is (0, 0).
