Answer: 2.0
Step-by-step explanation:
To round 1.965 to the nearest tenth consider the hundredths’ value of 1.965, which is 6 and equal or more than 5. Therefore, the tenths value of 1.965 increases by 1 to 0.
1.965 rounded to the nearest tenth = 2.0

The equation of parabola is y = -8(x -3)² - 9.
<h3>Define parabola.</h3>
A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
Given Data
Focus = (3, -9)
Directrix: y = -5
The focus-passing line has an equation of x = -5 that is perpendicular to the directrix. The symmetry line of a parabola is seen here.
The parameter of the parabola is the separation between the focus and the directrix, so
p = -9 - 3
p = -12
p = 12
The distance between the focus and the directrix is divided into two equal portions by the parabola's vertex, which is located on the line of symmetry. Its coordinates are as follows: (3,-9).
Since a parabola moves in the opposite direction of y, its equation is
y -(-9) = -2(4(x -3)²)
y + 9 = -8(x-3)²
y = -8(x -3)² - 9
The equation of parabola is y = -8(x -3)² - 9.

Hello,
First of all, relax and take a deep breath right before you start.
Alright, so algebraic word problems are tricky sometimes. I am glad I don’t have to do them much. Once you understand more or less what to do, you should be fine!
I would need an example problem if you have one.
If not, then remember that you have to work with what you know, which is what you can start with and what you need to end with.
For instance, a phone company sells phones at $900 each. For a family discount, after 2 phones are bought, each additional phone is $100 off.
Find an expression representing the phone company’s prices.
2*900 + (900x - 100x)
x represents how many additional phones were bought.
If a family bought 6 phones:
2*900 + (900x - 100x)
2 in front and 4 as x gives 6
That expression becomes
2*900 + [900(4) - 100(4)]
= $5000
I hope that helped!
