It would be 6,300 millimeters
Answer:
23+0.05m=88.65
Step-by-step explanation:
0.05m=65.65
m=1,313
i think this is right, I am sorry if it is wrong...
Answer:
6
Step-by-step explanation:
x/2+5=8
x/2=8-5= 3
x= 3×2= 6
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>
