The answer is A) -4/25 because when you multiply 8/15 and -3/10, you can simplify the expression to 4/5 times -1/5, which equals -4/25.

If p(x) = x^2 – 1 and q(x)=5(x-1), which expression is equivalent to (p – q)(x)? 5(x – 1) – x^2 – 1 (5x – 1) – (x^2 – 1) (x^2 –

Murrr4er [49]

P(x) = x^2 - 1
q(x) = 5(x - 1)
(p - q)(x) = p(x) - q(x) = (x^2 - 1) - 5(x - 1)

Find the Cartesian coordinates of the given polar coordinates. Then plot the point. (a) (2, π) (x, y) = WebAssign Plot WebAssign

Allisa [31]

Answer:

(a) ∴(x,y)= (-2,0)

(b) ∴(x,y)= (-2, $-2\sqrt3$ )

(c) ∴(x,y)= $(2\sqrt2,-2\sqrt 2)$

Step-by-step explanation:

To convert from polar coordinate to Cartesian Coordinate(x,y)

x = r cos θ
y = r sin θ

(a)

Here r = 2 and θ = π

x= 2 cos π = -2

y= 2 sin π = 0

∴(x,y)= (-2,0)

(b)

Here r = 4 and $\theta=-\frac{2\pi}{3}$

x= 4 cos $(-\frac{2\pi}{3})$ $=4\times (-\frac12)$ = - 2

y= 4 sin $(-\frac{2\pi}{3})$ $=4\times (-\frac{\sqrt3}{2})$ = $=-2\sqrt3$

∴(x,y)= (-2, $-2\sqrt3$ )

(c)

Here r= -4 and $\theta= \frac{3\pi}{4}$

$x=-4 cos (\frac{3\pi}{4})=-4 \times (-\frac1{\sqrt2)}=2\sqrt2$

$y=-4 sin(\frac{3\pi}{4})=-4\times \frac{1}{\sqrt2} =-2\sqrt 2$

∴(x,y)= $(2\sqrt2,-2\sqrt 2)$
