Answer:
Step-by-step explanation:
The following formula tells us that a quadratic equation can be solved:
which gives us the real and distinct roots
We have been given an equation:
Here, on comparing it with general quadractic equation which is:
Here, a=4,b=6 and c=2
On substituting the values in the formula to find D
Now, to find x:
we have a formula:
On substituting the values we get:
On simplification:
2000lb=1 ton
1 us ton is equal to 2000lbs
The surface area is the area of all the surfaces. Let's find the area of the square and the four triangles and add them together:
Square:
Triangles 1, 2, 3, & 4:
Now add them all up:
So the surface area of the square pyramid is 340 square inches.
The functions and their descriptions are:
- Polynomial: and
- Logarithm:
- Exponential
<h3>How to describe the functions?</h3>
The functions are given as:
The functions would be described based on the type of function they represent.
Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.

Answer:
x ≥5
Step-by-step explanation:
-2x ≤ -10
Divide by -2 Remember to flip the inequality symbol
-2x/-2 ≥ -10/-2
x ≥5
