Subtract the 17190 from the 21840. you get 4650. 4650 divided by 21840 is 0.21. The percent decrease is 21%

Answer: The cost of operation was reduced by 21.29%.

Step-by-step explanation:

Since we have given that

Cost of operation earlier = $21,840 per month

Cost of operation now = $17,190 per month

Difference between them is given by

$21,840 - $17,190

=$4,650

Percentage by which the cost of operation was reduced is given by

\dfrac{4650}{21840}\times 100\\\\=21.29\%

Hence, the cost of operation was reduced by 21.29%.

Determine where the function is increasing, decreasing, and constant.
Rama09 [41]

Answer:

Step-by-step explanation:

How does y change as x increases over a range?

As x increases from -6 to -4, y decreases from 0 to -7

It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant

As x increases from -4 to 0, y increases from -7 to 4

It is an increasing function in this range.

For x increasing from zero, y becomes less and less

It is a decreasing function in the range larger than x = 0

How do I find a7? Currently getting a even #
Katarina [22]

we know that a₁ = 1, and aₙ = aₙ₋₁ + 2, is another way of saying, we add 2 to get the next term, namely, 2 is the common difference.


\bf n^{th}\textit{ term of an arithmetic sequence}
\\\\
a_n=a_1+(n-1)d\qquad
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\[-0.5em]
\hrulefill\\
a_1=1\\
d=2\\
n=7
\end{cases}
\\\\\\
a_7=1+(7-1)2\implies a_7=1+12\implies a_7=13

Find the factors of f(x) given that x = 5 is a zero.
77julia77 [94]
  • If x = 5 is a zero of the given polynomial, then,
  • (x - 5) is a factor of the polynomial. [Since, x = 5 or, x - 5 = 0]
  • Now, divide the polynomial with (x - 5) using long division method. (See the picture)
  • We get (x^2 - x - 6) as the quotient.
  • Now, factorise the above polynomial:
  • (x^2 - x - 6)
  • = (x^2 - 3x + 2x - 6)
  • = x(x - 3) + 2(x - 3)
  • = (x - 3)(x + 2)
  • Therefore, x^3 − 6x^2 − x + 30 = (x − 5)(x − 3)(x + 2)

<u>Answer</u><u>:</u>

<u>B.</u><u>(x − 5)(x − 3)(x + 2)</u>

Hope you could get an idea from here.
