The slope is 2, because you subtract the points 3,17 from 7,25 to get 8/4/ Simplify that into 2.

Answer:

25. No slope

Step-by-step explanation:

25. Y2 - Y1 / X2 - X1

= -8 - (-3) / 9 - 9

= -5 / 0

= no slope; straight line

Use this formula (Y2 - Y1 / X2 - X1) for each ques.

HELP ON THIS PROBLEM!! Solve the following 0deg< x< 360deg: cos x= cos 2x

blsea [12.9K]

Answer:

$x=0^\circ,120^\circ,240^\circ,360^\circ$

Step-by-step explanation:

Use identities to set the equation up as a quadratic

$\cos x=\cos 2x;\:0^\circ \leq x \leq 360^\circ\\\\\cos x=2\cos^2 x-1\\\\0=2\cos^2 x-\cos x-1$

Make the substitution u=cos(x) and solve the quadratic

$0=2u^2-u-1\\\\0=(2u+1)(u-1)$

$\displaystyle 0=2u+1\\\\0=2\cos x+1\\\\-1=2\cos x\\\\-\frac{1}{2}=\cos x\\\\120^\circ,240^\circ=x$

$0=u-1\\\\0=\cos x-1\\\\1=\cos x\\\\0^\circ,360^\circ=x$

Hence, $x=0^\circ,120^\circ,240^\circ,360^\circ$

The probability that a region prone to hurricanes will be hit by a hurricane in any single year is 0.1 and independent of other

ludmilkaskok [199]

Answer:

0.40951

Step-by-step explanation:

P(none in five years) = 1 - 0.1 = 0.9

P(at least one) = 1 - P(none in five years)

= 1 - $0.9^{5}$

= 1 - 0.59049

= 0.40951

So the probability of a hurricane hit at least once in the next 5 years is 0.40951

Lots of points.

Kazeer [188]

Answer:

1. Not a function.

2. This is a function.

3. This is a function.

Step-by-step explanation:

1. 13 maps on to 4 and -4 so not a function.

2 and 3 - these both pass the vertical line test so they are functions.
