Solve for x on the domain 0 < x < 12:<br> cos x= -0.814

Morgarella [4.7K]

Answer:

Replace 10.0 with 10.04

Step-by-step explanation:

$\cos(x) = - 0.814$

$\cos {}^{ - 1} ( - 0.814) = x$

$x = 2.52$

Next, use the identity

$\cos(x) = \cos(2\pi - x)$

$\cos(2.52) = \cos(2\pi - 2.52)$

$\cos(2.52) = \cos(6.28 - 2.52)$

$\cos(2.52) = \cos(3.76)$

So another solution is 3.76

After that, use the identity

$\cos(x + 2\pi) = \cos(x)$

So use that for 2.52 and 3.76

$\cos(2.52 + 2\pi) = \cos(8.80)$

8.80 is one solutiin

$\cos(3.76 + 2\pi) = \cos(10.04)$

A specific brand of gourmet chocolate candy contains 7.00 gg of dietary fat in each 22.7-gg piece. How many kilograms of dietary

Oduvanchick [21]

Answer:

635599482kg

Step-by-step explanation:

A gourmet chocolate candy has 7.00 gg of dietary fat in each 22.7-gg piece

for the 22.7 piece , the gg is 7 x 22.7 = 158.9gg in total

1gg = 2204622.6218488 lbs

158.9gg in total = 158.9 x 2204622.6218488 = 350314534.612

for the box of 4.00 lblb of candy

it is 350314534.612 x 4 = 1401258138.45lb

since our answer is needed in kilograms we convert 1401258138.45lb to kilograms

1lb = 0.453592kg

1401258138.45lb = 1401258138.45lb x 0.453592kg = 635599481.513 ≈ 635599482kg
