Find the distance between the points (4, –2) and (0, 10).

madam [21]

$A(4,-2) \\B(0, 10) \\AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\AB=\sqrt{(0-4)^2+(10-(-2))^2} \\AB=\sqrt{16+144} \\AB=\sqrt{160}\approx\boxed{12.65} \\$

The answer is D.

Hope this helps.

Identify the relative maximum value of g(x) for the function shown below.<br> G(x)=x^3-3x^2+2

Sunny_sXe [5.5K]

Answer:

To find the relative maximum value of the function we need to find where the function has its first derivative equal to 0.

Its first derivative is -7*(2x)/(x^2+5)^2

7*(2x)/(x^2+5)^2 =0 the numerator needs to be eqaul to 0

2x=0

x=0

g(0) = 7/5

The relative maximum value is at the point (0, 7/5).

In our solar system, 6 of the 8 planets have moons. What percentenge of the planets have moons

s2008m [1.1K]

Use the information to form a ratio... 6:8 or 6/8. Now set it equal to a ratio per 100...

6/8 = x/100

Cross multiply

8x = 600
x = 600/8
x = 75

75% have moons

Is the following statement correct? Explain.

Maksim231197 [3]

Answer: The answer is NO.

Step-by-step explanation: The given statement is -

If the graph of two equations are coincident lines, then that system of equations will have no solution.

We are to check whether the above statement is correct or not.

Any two equations having graphs as coincident lines are of the form -

$ax+by=c,\\\\dax+dby=dc,\\\\\textup{where}~~d\neq 1.$

If we take d = 1, then both the equations will be same.

Now, subtracting the second equation from first, we have

$a(1-d)x+b(1-d)y=c(1-d)\\\\\Rightarrow ax+by=c,~\textup{since}~d\neq 1,~\textup{so}~1-d\neq 0.$

Again, we will get the first equation, which is linear in two unknown variables. So, the system will have infinite number of solutions, which consists of the points lying on the line.

For example, see the attached figure, the graphs of following two equations is drawn and they are coincident. Also, the result is again the same straight line which has infinite number of points on it. These points makes the solution for the following system.

$2x+5y=10,\\\\6x+15y=30.$

Thus, the given statement is not correct.
