Answer:
discriminant=0
Number of real solutions=1


Step-by-step explanation:

Given the equation:
-9x^2-6x-1=0
Let a: coefficient of x^2
Let b: coefficient of x
Let c: constant
a=-9
b=-6
c=-1
The formula of the discriminant is given by:
discriminant= b^2 - 4ac
discriminant= (-6)^2 - 4(-9)(-1)
= 36 - 36 = 0
We know that:
If discriminant<0 then the equation has no real root
If discriminant=0 the equation has one real root
If discriminant>0 the equation has 2 real roots

Here we got discriminant=0 so the quadratic equation has 1 real root.

Hello sir!
It seems as if this is a statement? Seemingly this is David Hilbert's mathematical problem that has yet to be solved.

 "The Riemann hypothesis implies results about the distribution of prime numbers. Along with suitable generalizations, some mathematicians consider it the most important unresolved problem in pure mathematics (Bombieri 2000). The Riemann hypothesis, along with Goldbach's conjecture, is part of Hilbert's eighth problem in David Hilbert's list of 23 unsolved problems; it is also one of the Clay Mathematics Institute's Millennium Prize Problems."

Hope this helps! :)

Question 3
wariber [46]

Answer:

Incorrect

The correct answer is 1/6

Step-by-step explanation:

Freddy is incorrect. You are not supposed to subract the denominators. When you are solving the equation you have to find a common denominator. You can only subtract the numerator, and the denominator is the same.

Find the LCM. The LCM in this case is 6.

\frac{3}{6} -\frac{2}{6}

Remember, only subtract the numerators. The denominator will still be 6.

\frac{1}{6}

1/6 is the correct answer. I hope this helps you!

wariber [46]

Answer:

4 square feet

Step-by-step explanation:

We can use Ratio to solve this question

It takes 15 minutes to paint 60 square feet

This is written as:

15:60

Divide both sides by 15

1:4

Therefore it takes Painter Paul 1 minute to paint 4 square feet

Bill invested $4000 at 6%
stiks02 [169]

We have to find the,

Accumulated amount at end of 12 years.

The formula we use,

→ A = P(1+r)^t

It is given that,

→ P = $4000

→ t = 12 years

Then r will be,

→ 6%

→ 6/100

→ 0.06

Then the total amount is,

→ P(1+r)^t

→ 4000 × (1 + 0.06)^12

→ 8048.79

Thus, $ 8048.79 is the amount.
