If x and y vary inversely, and x = 8 when y = 1/4, what is y when x = -4?

Alinara [238K]

$y \propto \dfrac 1x\\\\\implies y = \dfrac kx \\\\\implies \dfrac 14 = \dfrac k{8}\\\\\implies k=2\\\\\text{When}~ x =-4\\\\y = \dfrac{k}{x} = \dfrac{2}{-4}= -\dfrac 12$

Algebra 2: PLEASE HELP ME!!

vfiekz [6]

Looks more like Trig than Algebra II

They want us to apply the sum angle formula to $\sin(x + \frac{5 \pi}{6})$

5π/6 is 150°; I find it easier to think in degrees.

When the tangent of x is 3/4 that's a right triangle with opposite 3, adjacent 4 so hypotenuse 5. So a sine of 3/5 and a cosine of 4/5, both positive because we're told x is in the first quadrant.

The sine sum angle formula is

$\sin(a+b) = \sin a \cos b + \cos a \sin b$

$\sin(x+\frac{5\pi}{6}) = \sin x \cos \frac{5\pi}{6} + \cos x \sin \frac{5\pi}{6}$

We know sin 150° = sin 30° = 1/2 and cos 150° = - cos 30° = -√3/2

$\sin(x+\frac{5\pi}{6}) = \frac 3 5 (- \sqrt{3}/2) + \frac 4 5 (1/2)$

$\sin(x+\frac{5\pi}{6}) = \dfrac{ 4- 3\sqrt{3}}{10}$

Joe's company sold insurance policies over the phone. Last month, 2 employees sold three hurricane policies, 6 employees sold tw

ehidna [41]

The probability that the employee sold two hurricane policies or sold one hurricane policy is 15/17.

According to the statement

Number of employees who sold three hurricane policies is 2

Number of employees who sold two hurricane policies is 6

Number of employees who sold 1 hurricane policies is 9

SO,

The total number of employees is 2+6+9=17.

The number that sold two hurricane policies or sold one hurricane policy is 6+9=15,

so the Probability = Total number of policies sold / total number of employees

Probability = 15/17

So, The probability that the employee sold two hurricane policies or sold one hurricane policy is 15/17.

luda_lava [24]

Answer:

330 miles

Step-by-step explanation:

Use the slope intercept form of a line.

y = mx + b

b will be the constant or the daily cost to rent the car. The x is the number of miles. The y is the total cost and the m is the cost per mile.
