Answer:
Step-by-step explanation:
This problem gives one the following equation to model the graph of a line: (). The problem asks one to find the value of (x) when (y=0). Rather than using the graph, an easier way to solve this problem is to substitute (0) in for the value of (y) and then solve for (x) using inverse operations.
Substitute,
Inverse operations,
Round:
As one can see on the graph, this result is very close to the value at which the graph intersects the (x) axis. Thus, one can conclude that (x) does indeed approximately equal (1.4)
Answer:
Then the area of the triangle is 240 m²
Step-by-step explanation:
Area of a triangle:
The area of a triangle is given by the multiplication of its height and altitude, divided by 2.
In this question:
Base = 24m, altitude = 20m. So
Then the area of the triangle is 240 m²

800 - 900 = -100. = 100/800=.125 x 100 = 12.5% increase.

Step-by-step explanation:
Given a utility function U(q) = -q²-4q+2 in this case, depending on demand (q), this is function because it is a relationship or correspondence between two magnitudes, so that each value of the first corresponds to a single value of the second (or none); for example to q=-2 U(q) = 6, this means that for a demand (-2) the utility will be maximum (6)
, and to -∞<q<(-4-√24)/2 ∧ (-4+√24)/2<q<∞ the utility will be negative; (-4-√24)/2<q< (-4+√24)/2 the utility will be positive and q=(-4-√24)/2 ∧ q= (-4+√24)/2 there will be no utility
