Answer
y= 3/2 + 8
Hope I helped you
Answer:
wouldn't it be 3,12.....................
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>
The equation to find the volume of a pyramid is V=
3.) V=
→ Multiply the top V=
→ Divide by 3 V=
4.) V=
→ Multiply the top V=
→ Divide by 3 V=59.904 or V=59.9
5.) Since you need to find h you put the V value in and keep the h value blank. 1,350=
→ 1,350=
→ Multiply 3 by both sides 3×1,350=
×3 → 4,050=225×h → Divide 225 from both sides 4,050÷225=225×h÷225 → 18=h
I hope that helps!
Answer:
5 miles per hour
Step-by-step explanation:
It takes the dog 2/15 hours to run 2/3 miles.
Therefore,
The rate in mile per hour is
(2/3)/(8/14) = (2/3) X (15/2)
= 15/3 = 5miles per hour
