1 answer:

7 0

Not sure if that's a multiplication or a composition. It doesn't matter. Both f and g have a domain of all real numbers. The domain of

$( f \circ g)(x)=f(g(x))$

is the same as the domain of g(x), all real numbers

Answer: all real numbers

Answer:

The answer is 70 degrees.

Step-by-step explanation:

1. All the angles in a circle add up to 360, and the red square thing in the TVU angle means it's a 90 degree angle.

2. Add 150 plus 50 plus 90 = 290

3. 360 degrees (total) - 290 degrees = 70 degrees! :)

A woman plans to buy some bottles of alcohol, a bottle of Heineken goes for $800 while that of monster drink $250. she doesn't h

Alja [10]

Answer:

The inequalities that must be satisfied is

$x + y \leq 32$

$x(800) + y(250) \leq 3500$

Step-by-step explanation:

Let the number of Heineken bottles be x

Let the number of monster drink bottles be y

Her crate cannot hold more than 32, This situation can be represented as

$\text{Number of Heineken bottles + number of monster drink bottles } \leq 32$

That is

$x + y \leq 32$ ------------------------(1)

Cost of one Heineken bottles = $800

Cost of one monster drink bottles = $250

then

$x \times \text{cost of one Heineken bottle } + y \times \text{ cost of one monster drink bottle} \leq 3500$ x

$x(800) + y(250) \leq 3500$ ------------------(2)
