Find the sum and product of the roots of the equation 5x^2+11x-3=0 ?

1 answer:

5 0

I hope this helps you

disctirminant=b^2-4ac

b=11

a=5

c= -3

disctirminant =11^2-4.5. (-3)

disctirminant =121+60

disctirminant =181

x1=-11+ square root of 181/2.5

x2=-11- square root of 181/2.5

For a specific location in a particularly rainy city, the time a new thunderstorm begins to produce rain (first drop time) is un

ikadub [295]

Answer:

b) 0.0608

Step-by-step explanation:

As it is mentioned that the next two days i.e 24 hours, the probability of the rain is uniformly distributed

Therefore the rain probability is

$= \frac{T}{24}$

where,

T = Length of the time interval

Plus, as we know that rain is independent

So let us assume the rain between the 8: 40 AM and 2: 35 PM on single day is P1 and the time interval is 5 hours 55 minutes

i.e

= 5.91666 hours long.

So, P1 should be

$= \frac{5.91666}{24}$

= 0.2465

Now we assume the probability of rain on day 2 is P2

So it would be same i.e 0.2465

Since these events are independent

So, the total probability is

$= 0.2465 \times 0.2465$

= 0.0608

Hence, the b option is correct

Point B is in the interior of ∠AOC, m∠AOC = 108°, m∠AOB = 3m∠BOC. Find m∠AOB.

valentinak56 [21]

If point is the interior of <AOC ,
then m<AOB + m<BOC = m< AOC ( angle addition postulate ) eq 1
(3m<BOC ) + m <BOC = m <AOC { m<AOB = 3m<BOC)
4m <BOC = 108
m<BOC = 27

m<AOB + m <BOC = m < AOC
m<AOB = 108 - 27
m <AOB = 81
