Answer:

x<-25

Step-by-step explanation:

-10x>250

Divide by -10 on both sides

-10x/-10>250/-10

You are left with x on one side and 250 divided by -10 is 25. Because you divided by a negative the sign is flipped. This leaves you with

Two points in the Cartesian plane are A(2.00 m, −4.00 m) and B(−3.00 m, 3.00 m). Find the distance between them and their polar

Brrunno [24]

The distance between the two points is $d=8.6m$

The polar coordinate of A is $\left(4.47,296.57\right)$

The polar coordinate of B is $\left(4.24,135\right)$

Explanation:

The two points are $A(2,-4)$ and $B(-3,3)$

The distance between two points is given by,

$d=\sqrt{(2+3)^{2}+(-4-3)^{2}}\\d=\sqrt{(5)^{2}+(-7)^{2}}\\d=\sqrt{25+49}\\d=8.6$

Thus, the distance between the two points is $d=8.6m$

The polar coordinates of A can be written as $(Distance, tan^{-1} \frac{y}{x} )$

Distance = $\sqrt{x^{2} +y^{2} }$

Substituting $A(2,-4)$ , we get,

Distance = $\sqrt{2^{2} +(-4)^{2} }=\sqrt{4+16 }=4.47$

$tan^{-1} \frac{y}{x} =tan^{-1} \frac{-4}{2}=-63.43$

To make the angle positive, let us add 360,

$\theta=360-63.43=296.57$

The polar coordinate of A is $\left(4.47,296.57\right)$

Similarly, The polar coordinate of B can be written as $(Distance, tan^{-1} \frac{y}{x} )$

Distance = $\sqrt{x^{2} +y^{2} }$

Substituting $B(-3,3)$ , we get,

Distance = $\sqrt{(3)^{2}+(3)^{2}}=4.24$

$tan^{-1} \frac{y}{x} =tan^{-1} \frac{3}{-3}=-45$

To make the angle positive, let us add 360,

$\theta=180-45=135^{\circ}$

The polar coordinate of B is $\left(4.24,135\right)$

Q2: Explain the difference between the solution to an equation and the solution to an inequality. (dba 3

CaHeK987 [17]

The solution(s) of a system of linear equations give points of intersection of specific lines or planes.

The solution(s) of a system of linear inequalities give areas of intersection wherein any specific pair of points or lines are solutions.

PROCESS-WISE there are little differences between solving systems. However, multiplication and division by negatives reverses the signs in inequalities.

8) A rectangle measuring 25cm long and 4cm wide has the SAME AREA as a square.

MakcuM [25]

Answer:

Step-by-step explanation:

The area of the rectangle is 100cm, so if the area of the square is the same as the rectangle, then the side of the square would be 10. 10 x 10 is 100.

Resta -7/10 -(-4/15)

Snezhnost [94]

Answer:

-13/30

Step-by-step explanation:

I used KCC. It is a method when you keep you 1st # the same, change subtraction to addition and then change the last # to its opposite. So after KCC, the equation would be -7/10 + 4/15
