Answer:
Here's what I get
Step-by-step explanation:
The formula for a quadratic equation is
ax² + bx + c = 0
The quadratic formula gives the roots:
D is the discriminant.
It tells us the number of roots to the equation — the number of times the graph crosses the x-axis.
It doesn't matter if the graph opens upwards or downwards.
If D > 0, the graph crosses the x-axis at two points.
If D = 0, the graph touches the x-axis at one point.
If D < 0, the graph never reaches the x-axis.
Your graph must look like one of the two graphs on the right in the Figure below.
Answer:
2.55°C
Step-by-step explanation:
Calculate the temperature at the 2 given depths
x = 1200
T = = 3.75
x = 3750
T = = 1.2
Difference in temperature = 3.75 - 1.2 = 2.55°C
A:

Y = 3
B:
n = 16

What is the question? I don't get it?
After solving the equation we get values of x:
Step-by-step explanation:
We need to find the value of x from the equation:
Solving the expression:
Using the Zero Factor Principle: if ab=0 then a=0 and b=0
So,
So, After solving the equation we get values of x:
