It's a quadratic equation. Solve it through factorisation.
5s^2 - 14s - 3 = 0
(5s + 1)(s - 3) = 0
5s + 1 = 0
or
s - 3 = 0
Therefore
s = -1/5
or
s = 3
I'm assuming your allowed to use a calculator for this? That's what I would do.
![\sqrt{108} = 10.39](https://tex.z-dn.net/?f=%20%5Csqrt%7B108%7D%20%20%3D%2010.39)
To go about the fraction, take the whole number and times it by the denominator, then add in the numerator to create a new fraction(a whole one not mixed). Then simply divide the numerator by the denominator.
![9 \times 20 = 180](https://tex.z-dn.net/?f=9%20%5Ctimes%2020%20%3D%20180)
![180 + 13 = 193](https://tex.z-dn.net/?f=180%20%2B%2013%20%3D%20193)
193 is the new numerator and the new whole fraction is this and dividing it out gives you,
![\frac{193}{20} = 9.65](https://tex.z-dn.net/?f=%20%5Cfrac%7B193%7D%7B20%7D%20%20%3D%209.65)
For the third one, just input it into a calculator,
Answer: here is ur answer
Step-by-step explanation:
Given equation : y=ax^2
Taking a to the other side we have, x^2=(1/a)*y
This equation describes a parabola that opens up.
When a is negative, the focus is on the negative y-axis, therefore, the parabola opens down.
The answer is a. down.
