Answer: 27,600

Step-by-step explanation:

Ok, there could be two answers to this question. If the question is asking how much he would make if it was .15% more, the total would be 27,600/a year

However, if it's asking .15% <u>of</u> 24,000, your answer would be 3,600 ( as in the extra he would be making)

To find the answer, you would have to multiply 24,000*.15 (your starting value times how much you would like to multiply it by)

True or False

Rama09 [41]

Answer:

True

Step-by-step explanation:

Permutation is act of arranging members of a set while combination is selection of the items from collection.

The number of permutation of r object out of n is:

$^nP_r=\frac {n!}{(n-r)!}$

The number of combinations of r object out of n is:

$^nC_r=\frac {n!}{(n-r)!\times r!}$

Or,

$^nC_r=\frac {^nP_r}{r!}$

So, number of the permutations of r objects out of n is greater than number of the combinations of r objects out of n.

Which function models the area of a rectangle with side lengths of 2x - 4 units x - 1 units

elena-s [515]

The choices are missing but we can find the answer from the given information

Answer:

The function which models the area of the rectangle is A(x) = 2x² - 6x + 4

Step-by-step explanation:

The formula of the area of a rectangle is A = l w, where l is its length and w is its width

∵ The length of a rectangle is (2x - 4) units

∵ The width of the rectangle is (x - 1) units

- Use the formula of area to find its area

∵ A = l w

∴ A = (2x - 4)(x - 1)

Let us multiply the two brackets

∵ (2x - 4)(x - 1) = (2x)(x) + (2x)(-1) + (-4)(x) + (-4)(-1)

∴ (2x - 4)(x - 1) = 2x² + (-2x) + (-4x) + 4

- Add the like terms

∴ (2x - 4)(x - 1) = 2x² + (-6x) + 4

∴ (2x - 4)(x - 1) = 2x² - 6x + 4

Write A as a function of x

∵ The area of the rectangle is A(x)

∵ The area of the rectangle is 2x² - 6x + 4

∴ A(x) = 2x² - 6x + 4

The function which models the area of the rectangle is A(x) = 2x² - 6x + 4

M s

user100 [1]

Answer:

Step-by-step explanation:

s = 6m.... (given)

We need to find the value of s when m = 3

So plug m = 3 in the above equation, we find:

s = 6*3

s = 18
