Answer:

a^8 ÷ b^12

Step-by-step explanation:

a^-5 · b^-4 / a^-13 · b^8

when dividing exponents with the same bases, subtract the exponents

a^8 · b^-12

do not leave a negative exponent; put it into the denominator and it becomes positive

b^-12 = 1 /b^12

Solve 2csc^2x-2cscx-1=0 for 0° ≤ x ≤ 360°

umka21 [38]

Answer:

Step-by-step explanation:

2 csc²x-2 csc x-1=0

$\frac{2}{sin^2x} -\frac{2}{sin x} -1=0\\multiply~by~sin^2x\\2-2sin~x-sin^2x=0\\sin^2x+2sinx-2=0\\sin ~x=\frac{-2 \pm\sqrt{2^2-4*1*(-2)} }{2*1} \\=\frac{-2 \pm\sqrt{4+8} }{2} \\=\frac{-2 \pm\sqrt{4*3} }{2} \\=\frac{-2 \pm2\sqrt{3} }{2} \\=-1\pm\sqrt{3} \\|sin~x| \le ~1\\so~sin~x=-1+\sqrt{3} \\sin~x=\sqrt{3} -1\\x=sin^{-1}(\sqrt{3} -1) \approx 47.06^\circ,180-47.06\\or~x=47.06^\circ,132.94^\circ$

(-10, -10) and (-2, -3) find the slope.

ankoles [38]

The slope is 7/8.

Slope formula is the change in y over the change in x,
M=y2-y1 / x2-x1

M= -3 - (-10) / -2 - (-10)

Remember that two negatives equal a positive.

That makes the equation:
M= -3 + 10 / -2 + 10

M= 7/8
