Answer:

Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

Convert the rectangular coordinates (4√3,−4) to polar form. Let r>0 and 0≤θ<2π.

spayn [35]

Answer:

(8,150)

Step-by-step explanation:

Polar form is in,

(r,theta).

To find r, apply pythagorean theorem using both coordinates to find r.

$(4 \sqrt{3} ) {}^{2} + ( - 4 {}^{2} ) = {r}^{2}$

$48 + 16 = {r}^{2}$

$r = 8$

To find theta, since we know the opposite and adjacent side, apply the tangent function.

$\tan(x) = \frac{ - 4}{4 \sqrt{3} }$

Apply inverse tan function

$\tan {}^{ - 1} ( \frac{ - 4}{4 \sqrt{3} } ) = - 30$

Since the degrees have to be in between 0 and 360. Add 180 to -30.

$- 30 + 180 = 150$

So the answer is

(8,150).

Find the surface area of the following triangular pyrarnid using the net.

JulsSmile [24]

Answer:

B 84 is our answer

Step-by-step explanation:

triangle formula for surface area is base x height divided by 2 so 7 x 6 = 42 42 ÷ 2 = 21 All the other triangles are going to be the same so 21 x 4 = 84 so 84 is our surface area

Answer:

m=-5/4

Step-by-step explanation:

the slope is always defined as "the change in y over the change in x" m= y2-y1/x2-x1
