Does anyone know how to solve the second half of this question?
Masja [62]

Answer:

see explanation

Step-by-step explanation:

given

f'(x) = 12cos x - 4sin x, then

f'(\frac{4\pi }{3}) = 12cos(\frac{4\pi }{3}) - 4sin(\frac{4\pi }{3})

[ cos(\frac{4\pi }{3}) = -cos(\frac{\pi }{3}), sin(\frac{4\pi }{3} = - sin(\frac{\pi }{3}) ]

= -12cos(\frac{\pi }{3}) + 4sin(\frac{\pi }{3})

= - 12 × \frac{1}{2} + 4 × \frac{\sqrt{3} }{2}

= - 6 + 2\sqrt{3} ≈ - 2.536 ( 3 dec. places )

If an arena charges $7. 50 to park in satellite parking and $12. 00 to park in an arena lot, how much will be made from parking
Oksanka [162]

Parking 11,000 automobiles at the venue and 4,600 in satellites will bring in total $166,500.

<h3>Define multiplication.</h3>

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical size. Let's use the ice creams as a multiplication example to help us comprehend. There are two such groupings, and each group has ice cream.

Given,

If an arena charges $7. 50 to park in satellite parking and $12. 00 to park in an arena lot,

Multiplying:

$7.5 x 4,600 = satellite parking

$34,500 = satellite parking

The next step is to determine how much it will cost to park in the arena lot.

$11,000 ×12 = arena lot

$32,000 = arena lot

Let's now calculate the entire revenue from parking.

Total earnings equal $132,000 + $34,500.

Amount made in total is $166,500.

In conclusion Parking 11,000 automobiles at the venue and 4,600 in total satellites will bring in $166,500.
