4 0

Answer:

\huge \frac{8}{45}

Step-by-step explanation:

\frac{9}{10}  -  \frac{13}{18}  \\  \\  = \frac{9 \times 9}{10 \times 9}  -  \frac{13 \times 5}{18 \times 5} \\   \\  = \frac{81}{90}  -  \frac{65}{90}  \\   \\ =  \frac{81 - 65}{90}\\  \\  =  \frac{16}{90}  \\  \\  =  \frac{8}{45}  \\

A store owner buys a total of 4,000 items for two different products. For shipping costs, it is $0.10 per item of product A and
baherus [9]
x + y = 4,000
0.1x + 0.04y = 352

Product A represents x and product B represents y. The first equation is the total number of items the store owner buys. The second equation is cost per item for both products. The above system of equations can be used to determine how much product A and product B the store owner bought.

Can someone please explain this problem to me idk what I am doing wrong and can you draw the problem for me thanks
Bogdan [553]

Answer:

  you're not doing anything wrong

Step-by-step explanation:

In order for cos⁻¹ to be a function, its range must be restricted to [0, π]. The cosine value that is its argument is cos(-4π/3) = -1/2. You have properly identified cos⁻¹(-1/2) to be 2π/3.

__

Cos and cos⁻¹ are conceptually inverse functions. Hence, conceptually, cos⁻¹(cos(x)) = x, regardless of the value of x. The expected answer here may be -4π/3.

As we discussed above, that would be incorrect. Cos⁻¹ cannot produce output values in the range [-π, -2π] unless it is specifically defined to do so. That would be an unusual definition of cos⁻¹. Nothing in the problem statement suggests anything other than the usual definition of cos⁻¹ applies.

__

This is a good one to discuss with your teacher.
