2x2=4, 5x6=30
Not sure if they’re one expression, of so it’s (2x2)+(5x6)=34
Answer:
D) 0 = 2(x + 5)(x + 3)
Step-by-step explanation:
Which of the following quadratic equations has no solution?
We have to solve the Quadratic equation for all the options in other to get a positive value as a solution for x.
A) 0 = −2(x − 5)2 + 3
0 = -2(x - 5) × 5
0 = (-2x + 10) × 5
0 = -10x + 50
10x = 50
x = 50/10
x = 5
Option A has a solution of 5
B) 0 = −2(x − 5)(x + 3)
Take each of the factors and equate them to zero
-2 = 0
= 0
x - 5 = 0
x = 5
x + 3 = 0
x = -3
Option B has a solution by one of its factors as a positive value of 5
C) 0 = 2(x − 5)2 + 3
0 = 2(x - 5) × 5
0 = (2x -10) × 5
0 = 10x -50
-10x = -50
x = -50/-10
x = 5
Option C has a solution of 5
D) 0 = 2(x + 5)(x + 3)
Take each of the factors and equate to zero
0 = 2
= 0
x + 5 = 0
x = -5
x + 3 = 0
x = -3
For option D, all the values of x are 0, or negative values of -5 and -3.
Therefore the Quadratic Equation for option D has no solution.
Answer:
Step-by-step explanation:
We are told that pressure at sea level is 1 atmosphere and increases at a constant rate as depth increases.
We are provided two points as (0,1) and (23,3.3). To find function's formula we will find the line which passes through these points.
First of all we will find slope of this line.
Now we will find equation of this line in slope intercept form.
Our equation for this line will be .
Now let us write this for x as a function of p,
Therefore, our function's formula will be p(x) = 0.1x + 1.
