Answer:

She lost $2550.

Step-by-step explanation:

She bought 37 meters at $750/m.

37 m * 750/m = $27,750

She paid $27,750

She sold 28 m at $900/m

28 m * $900/m = $25,200

She sold $25,200

$25,200 - $27,750 = -$2550

She lost $2550.

Answer:

2553

Step-by-step explanation:

She bought 37 meters at $750/m.

37 m * 750/m = $27,750

She paid $27,750

She sold 28 m at $900/m

28 m * $900/m = $25,200

She sold $25,200

$25,200 - $27,750 = -$2550

She lost $2550.

Which of the following functions could be f(x) ?
notka56 [123]

Answer:

B.  f(x) = -x^3 - x^2 + 7x - 4

Step-by-step explanation:

For this problem, we want to find the fastest-growing term in our given expressions and equate them when x is - infinite and when x is infinite to see the given trends.

For each of these equations, we will simply take the terms with the highest power and consider those.  The two cases we need to consider is + infinite for x and - infinite for x.  Let's check each of these equations.

Note, any value raised to an even power will be positive.  Any negative value raised to an odd power will be negative.

<u>[A] - x^4</u>

<em>When x is +∞ --> - (∞)^4 -->  f(x) is -∞</em>

<em>When x is -∞ --> - (-∞)^4 --> f(x) is -∞</em>

<em />

<u>[B] - x^3</u>

<em>When x is +∞ --> - (∞)^3 --> f(x) is -∞</em>

<em>When x is -∞ --> - (-∞)^3 --> f(x) is ∞</em>

<em />

<u>[C] 2x^5</u>

<em>When x is +∞ --> 2(∞)^5 --> f(x) is ∞</em>

<em>When x is -∞ --> 2(-∞)^5 --> f(x) is -∞</em>

<em />

<u>[D] x^4</u>

<em>When x is +∞ --> (∞)^4 --> f(x) is ∞</em>

<em>When x is -∞ --> (-∞)^4 --> f(x) is ∞</em>

<em />

Notice how only option B, when looking at asymptotic (fastest-growing) values, satisfies the originally given conditions for the relation of x to f(x).

Cheers.

PLEASE HELP, TWENTY POINTS PLUS BRAINLIEST
Sedbober [7]
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.

What property is this called? 5(3x+6) <br> Please help me
Sladkaya [172]

Answer:

distributive property

Step-by-step explanation:

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers the first number can be distributed to both of those numbers and multiplied by each of them separately then adding the two products together for the same result as multiplying the first number by the sum
