Mathematics

1 answer:

Georgia [21]4 years ago

5 0

Answer:

d. √34 ≈ 5.82

Step-by-step explanation:

Both of choices B and D are valid calculations and should have resulted in the same estimate. Choice B, however, is incorrectly rounded, leaving choice D as the better answer.

___

The other answer choices do not result in a number between 5 and 6, so are clearly incorrect.

What’s the value of x ?

igor_vitrenko [27]

Answer:

x = 127

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6, thus

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

x + 120 + 100 + 128 + 133 + 112 = 720, that is

x + 593 = 720 ( subtract 593 from both sides )

x = 127

Plot the point (3, 2pi/3), given in polar coordinates, and find other polar coordinates (r, θ )of the point for which the foll

exis [7]

Answer:

(a) $(3, -\frac{4\pi}{3})$

(b) $(-3, \frac{5\pi}{3})$

Step-by-step explanation:

All polar coordinates of point (r, θ ) are

$(r,\theta+2n\pi)$ and $(-r,\theta+(2n+1)\pi)$

where, θ is in radian and n is an integer.

The given point is $(3, \frac{2\pi}{3})$ . So, all polar coordinates of point are

$(3, \frac{2\pi}{3}+2n\pi)$ and $(-3, \frac{2\pi}{3}+(2n+1)\pi)$

(a) $r>0,-2\pi\leq \theta$

Substitute n=-1 in $(3, \frac{2\pi}{3}+2n\pi)$ , to find the point for which $r>0,-2\pi\leq \theta$ .

$(3, \frac{2\pi}{3}+2(-1)\pi)$

$(3, -\frac{4\pi}{3})$

Therefore, the required point is $(3, -\frac{4\pi}{3})$ .

(b) $r$

Substitute n=0 in $(-3, \frac{2\pi}{3}+(2n+1)\pi)$ , to find the point for which $r>0,-2\pi\leq \theta$ .

$(-3, \frac{2\pi}{3}+(2(0)+1)\pi)$

$(-3, \frac{2\pi}{3}+\pi)$

$(-3, \frac{5\pi}{3})$

Therefore, the required point is $(-3, \frac{5\pi}{3})$ .

Substitute n=1 in $(3, \frac{2\pi}{3}+2n\pi)$ , to find the point for which $r>0,2\pi \leq \theta$ .

$(3, \frac{2\pi}{3}+2(1)\pi)$

$(3, \frac{2\pi}{3}+2\pi)$

$(3, \frac{8\pi}{3})$

Therefore, the required point is $(3, \frac{8\pi}{3})$ .
