A glacier in Alaska moves about 29.9 meters a day. About how much farther will it move in 1000 days than it will move in 100 day
satela [25.4K]
If it moves 29.9 meters a day, then we need to find the total amount of days:

1000 days + 100 days = 1100 days

Since it moves 29.9m per day, we can write:

29.9m x 1100 which equals 32 890m

So it moved 32 890m

Simplify the expression. What classification describes the resulting polynomial? (3x^2-11x-4)-(2x^2-x-6)
Gnoma [55]

The expression can be simplified to a polynomial of degree 2.

x^2 - 10x + 2

<h3>How to simplify the expression?</h3>

Here we have the expression:

(3x^2 -11x - 4) - (2x^2 - x - 6)

We can directly simplify this by taking the variable as common factor:

(3 - 2)*x^2 + (-11 + 1)*x + (-4 + 6)\\\\x^2 - 10x + 2

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.

Firdavs [7]

Answer:

Domain: All real numbers

Range: y\leq -3

Step-by-step explanation:

The domain is the set of all x values. The quadratic equation continue to operate over all x-values in both directions. The domain is all real numbers.

The range is the set of all y-values. Here the quadratic begins at -3 and continues in a downward direction forever. Then range is y\leq -3
