supermarket, but the cost is a little more at $2.10 per pound. You spend about $3 on gas every time you go to the specialty stor

e. How do you know if you are getting enough of the jelly beans to make the trip worthwhile? What two equations would you use to determine your break-even point? (Let C stand for the total cost and x represent the amount of jelly beans.) a. C = 3.00 + 1.30 x. C = 2.10 x b. C = 3.00 + 2.10 x. C = 1.30 x c. C = 2.10 x + 1.30 x. C = 3.00 d. C = 3.10 x. C = 3.00

Answer: The total weight of the items is 1.25 + 0.25 + 0.6 + 0.4 = 2.5 lb. 2.5 is 0.25 greater than 2.25, so not all the items can be added. If Li leaves out the extra game, which weighs 0.25 lb, she’d have the greatest possible weight allowed. Pls mark as  brainliest.

Solve the equation on the interval 0 less than or equals theta less than 2 pi .0≤θ<2π. secant StartFraction 5 theta Over 4 En
qaws [65]

Answer:  4π/15, 4π/3 and 28π/15 (in radians)

Step-by-step explanation:

sec 5\theta/4 =2

Recall that sec \theta = 1/cos \theta

1/cos (5\theta/4) =2

cos (5\theta/4) =1/2

Cos^{-1} \frac{1}{2} = 5\theta/4

This implies that

\mp60+360n=5\theta/4

\theta=4/5(\mp60+360n)= \mp48+288n

When  n=0, \theta=48

When  n=1, \theta=240, 336

Therefore the values of \theta between 0 and 2π are 48, 240 and 336. (All in degrees)

48 degrees= 4π/15 rad

240 degrees =4π/3 rad

336 degrees = 28π/15 rad

14. POLITICS Mi-Ling wants to mail at least 850 fliers encouraging voters to vote for the
mrs_skeptik [129]

f = amount of fliers expected to be mailed in 1 day.

a)

so, she has 5 days to mail those fliers, so

day 1........... 1f mailed out

day 2........... 2f mailed out

day 3........... 3f mailed out

day 4........... 4f mailed out

day 5........... 5f mailed out

so she'll be mailing out a total of 5f fliers, we know whatever "f" is, that total must be at least 850, now, it could be more, no less, could also be 850 exactly, but could also be more, 5f ⩾ 850.

b)

\bf 5f \geqslant 850\implies f\geqslant \cfrac{850}{5}\implies f\geqslant 170
