Answer:
Step-by-step explanation:
Rearrange the given x^2+3=9x in standard quadratic form:
1x^2 - 9x +3 = 0
Then the three coefficients are a = 1, b = -9 and c = 3.
The discriminant is √(b^2 - 4ac), or √(81 - [1][3]), or √78.
± √78
Thus, the roots are x = ----------------
2
Earthquakes can cause all of the above.
trigger other earthquakes - when there is a large magnitude earthquake it
lead to shake the earth's surface. Thus it can create more earthquakes on the same place or neighboring places.
cause billions of dollars - when there is a large disturbance it can destroy big buildings, homes, etc. Which is basically a billion dollar loss.
cause tsunami - If there is a disturbance in the earth's surface near sea's, etc there is chance of tsunami.
Answer:
Step-by-step explanation:
Hi there!
Let the smaller number be x and the larger number be 2x+1.
According to the question,
The sum of the numbers is 20 less than three
times the larger.
i.e x + (2x+1)= 3*(2x+1) - 20
or, x + 2x +1 = 6x + 3 -20
or, 3x + 1 = 6x - 17
or, 3x = 18
or x= 18/3
x = 6
And 2x+1 = 2*6+1 = 13.
Therefore the smaller number is 6 and larger number is 13.
Hope it helps!
Answer:
$40
Step-by-step explanation:
6 = .15x
6 / .15 = 40
First one is 7.73 (23.19/3)
Second one is 14.04 ((19.71/7.3) x 5.2)
