Answer: Choice D</h3>
======================================================
Explanation:
The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.
A solid boundary line means that points on the boundary are part of the solution set.
Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.
This is false because -20 is not larger than -1. It's the other way around.
This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.
The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.
Answer:
Option A
Step-by-step explanation:
Given differential equtaion is
As this equation contains derivatives and not partial derivatives, this equation is an ordinary differential equation and not a partial differential equation.
Here, denotes that x is an independent variable and y is a dependent variable.
Order of the differential equation is a number of the highest derivative.
Order of the given differential equation is 1.
We can write this ordinary differential equation as follows:
As this equation is of form , this is a linear differential equation.
So, option A. is correct as this is a linear ordinary differential equation.
we are given
where
price p( in dollars) of a new smartphone
t is the number of months since January
now, we can solve for t
step-1:
Add both sides by 4t^2
step-2:
Subtract both sides by p
step-3:
divide both sides by 4
step-4:
Take sqrt both sides
so, we get
..............Answer
Isiah determined that 5a2 is the GCF of the polynomial a^3 – 25a^2b^5 – 35b^4-<u>No,Isiah is not correct if he states that that 5a2 is the GCF of the polynomial</u>
Step-by-step explanation:
Firstly ,we divide each term by the GCF and if the term does not divide evenly, then it is not valid
so,
5a^2 divide by a^3
we see that we cannot divide 5a^2 by a^3 because firstly the power is higher and then there is no 5 number.Thus it is not the GCF
The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial.
Also we find that 5b^4 is a factor of -25a^2b^5 and -35b^4, but not a3. Additionally, a2 is a factor of a3 and -25a^2b^5, but not -35b^4.
