Determine two pairs of polar coordinates for (3,-3) when 0
Xelga [282]

The two pairs of polar coordinates for the given point (3, -3) with 0° ≤ θ < 360° are (3√2, 135°) and (3√2, 315°).

<h3>What is a polar coordinate?</h3>

A polar coordinate is a two-dimensional coordinate system, wherein each point on a plane is typically determined by a distance (r) from the pole (origin) and an angle (θ) from a reference direction (polar axis).

Next, we would determine the distance (r) and angle (θ) as follows:

r = √(3² + (-3)²)

r = √(9 + 9)

r = 3√2.

θ = tan⁻¹(-3/3)

θ = tan⁻¹(-1)

θ = 3π and 7π/4 (second and fourth quadrants).

Converting to degrees, we have:

θ = 135° and 315°.

Which graph represents the solution set for the system 2x + y ≤ 3 and y − x &gt; 2?
natka813 [3]
You can identify the lines and their colour either by
1. the y-intercepts.  
First equation has a y-intercept of 3 and second has a y-intercept of 2.
So first equation is blue, and second is red.
2. the slopes
First equation has a negative slope (so blue), and second has a positive slope (so red).

Now work on each of the equations.
1. first equation (blue)
If we put x=0, we end up with the equation y&le;3, the &le; sign indicates that the region is BELOW the BLUE line.
2. second equation (red).
If we put x=0, we end up with the equation y>2, the > sign indicates that the region is ABOVE the RED line AND the red line should be dotted (full line if &ge;).

So at the point, it won't be too hard to find the correct region.

To confirm, take a point definitely in the region, such as (-6,0) and substitute in each equation to make sure that both conditions are satisfied.

Rank the following from most precise to least precise.1.4515100.0034
aalyn [17]

The level of precision is given by the number of decimal places.

1.45 has a precision of 2 ( two decimal digits)

.0034 has a precision of 4 ( 4 decimal digits)

Numbers that end in zeros have negative precision:

100: has a precision of -2 ( 2 zeros)

15 : Whole numbers has precision 0.

From most precise to least precise:

.0034 - 1.45- 15 - 100

Plz help ...............................
soldier1979 [14.2K]

Answer:

It is the right-angled triangle.

Step-by-step explanation:

According to the Pythagorean theorem, a^{2}+b^{2}=c^{2}, which c is the longest side of the triangle.

So, 27^{2}+36^{2}=45^{2} if the triangle is right angle.

LHS=27^{2} + 36^{2} = 2025

RHS=45^{2}=RHS=45^{2} = 2025

∵LHS=RHS

∴It is a right-angled triangle.
