Answer:
This question is a rather easy one which can be answered by simply solving the embedded quadratic equation.
f(x) = -
+ 6x + 16
To make our solving easier, what we do is multiply the whole equation by -1. By so doing, we make "x" positive. Then, we have
f(x) =
- 6x - 16
Solving this equation quadratically, we have
+ 2x - 8x - 16 = and when we factorize this expression, we have
x(x + 2) -8(x + 2) =
(x - 8) (x + 2) = 0
x - 8 = 0, x + 2 = 0
x = 8, or x = -2
Since distance can not be in negative(minus), we then have our x to be 8 meters.

Answer:
736 N
Step-by-step explanation:
Area of the rectangular tile=length*breadth
=1.6*2.3 sq. metres
=3.68 sq . metres
Given, Maximum pressure sustainable by the tile=200N/sq.metres
Thus, the maximum force that can safely be applied to the tile=Pressure*Area
=200*3.68 N
=736 N
. Correct option C)5.38
<u>Step-by-step explanation:</u>
Here we have , Find the value of x. O is the center of the circle. Round your answer to the nearest hundredth. picture is attached . Let's find out:
In the given figure , Let's draw a line from center to the point where cord of length 8 unit is touching the circle or intersecting or , where this chord finishes . This line is radius of circle and is denoted by x , So now we have a right angle triangle with dimensions as :

By Pythagoras Theorem ,

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore ,
. Correct option C)5.38
It’s going to be B because
You need to set up a portportation to solve this question to do so you need to know that 3 tenths is 30% so you can do:
30/100 = x/1.7
So now you cross multiply doing 30X17=510
Finially X=510/100
