The equation C = 0.20x + 50 gives the cost C in dollars for renting a truck and

k0ka [10]

Answer:

0.20 dollars/mile

Step-by-step explanation:

The slope actually has units. It has the meaning of 20 cents per mile. The units are cents per mile.

But it can also be 0.20 dollars/mile which is probably the way you should interpret it in a math class. That way it matches the units of the 50 which is for certain in dollars.

If cosx cos(pi/7) + sinx sin(pi/7) = -(sqrt(2))/2, then x can equal...? (Check all that apply) (Will give medal & fan!) A. p

Svetlanka [38]

Answer:

Options B and D

Step-by-step explanation:

Given that

$cos x cos \frac{\pi}{7} +sinx sin \frac{\pi}{7} =\frac{-\sqrt{2} }{2}$

Use the formula for sum angles for Cos as

Cos A cos B +sin A sin B = cos (A-B)

we have

$cos (x-\frac{\pi}{7} ) = \frac{-\sqrt{2} }{2}$

First let us solve principal solution

cos negative in the II quadrant

Hence principal soluton is $\pi-\frac{\pi}{4} =\frac{3\pi}{4}$ + $\frac{\pi}{7}$

Again it is negative in third quadrant i.e. x = $\frac{5\pi}{4}$ + $\frac{\pi}{7}$

General solution is $\frac{5\pi}{4}$ + $\frac{\pi}{7}+2n\pi and\\\\\frac{3\pi}{4}$ + $\frac{\pi}{7}+2n\pi$

Options B and D
