Answer:

(B) Is the answer here

Step-by-step explanation:

Well a function’s domain can’t repeat no matter what.

Domain is X.

So the first one doesnt work since it repeats to every single digit that exists.

The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.

Answer:

B

Step-by-step explanation:

Hello There!

In order for the relations to be a function the x values may not repeat

For answer choice A the x value -2 repeats multiply times therefore the relation is not a function

For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices

For answer choice C the x values -3 and 2 repeat therefore it is not a function

For answer choice D the x value 2 repeats therefore the relation is not a function

So we can conclude that the correct answer is B

Given that 32✓2=2^a , find the value of a​
NNADVOKAT [17]

Answer:

Step-by-step explanation:

All you need is something that when you divide the right side (the way I've written it) by 2, you get 32 sqrt(2). So a must also have sqrt(2) in it. In addition, it must also have 16 as well so that when you multiply by 2, you get 32.

2a = 32*sqrt(2)                Divide by 2

a = 16*sqrt(2)

a car dealership sells 48 cars of the same model in one month. the average price of each car is $25,000 with a maximum variance
Umnica [9.8K]

Answer:

Range= $144,000

Step-by-step explanation:

The least amount for each car is 22,000 and the highest is 25,000

so assuming the dealer sells all of them the lowest price, the revenue would be, $1,056,000 (that would be the lowest revenue) and assuming he sells all the cars at the highest price, the dealer will get a revenue of $1,200,000. So the lowest revenue is 1,056,000 and the highest revenue is 1,200,000. So to find the range subtract the highest revenue by the lowest and you’ll get $144,000.

(5n2 – 4nm - 9m²) + (7n2 + 4nm +8m²) =
Flauer [41]

Answer:

\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2

Step-by-step explanation:

Given the expression

\left(5n^2\:-\:4nm\:-\:9m^2\right)\:+\:\left(7n^2\:+\:4nm\:+8m^2\right)

Remove parentheses: (a) = a

=5n^2-4nm-9m^2+7n^2+4nm+8m^2

Group like terms

=5n^2+7n^2-4nm+4nm-9m^2+8m^2

Add similar elements: 5n^2+7n^2=12n^2

=12n^2-4nm+4nm-9m^2+8m^2

Add similar elements: -4nm+4nm=0

=12n^2-9m^2+8m^2

Add similar elements:  -9m^2+8m^2=-m^2

=12n^2-m^2

Therefore, we conclude that:

\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2
