\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{6})~\hspace{10em} slope = m\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-6=-5[x-(-2)]\implies y-6=-5(x+2)


\bf y-6=-5x-10\implies y=-5x\stackrel{\downarrow }{-4}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{y-intercept}{(0,-4)}~\hfill

If b = 3, then 3x + y = 1 and bx - y = 3 are parallel.<br> True or <br> False ...?
Ulleksa [173]
I am absolutely sure that the task <span> b = 3, then 3x + y = 1 and bx - y = 3 is NOT parallel, which means that the statement represented above is FALSE.
To make sure you can check it using : </span>y=-3x+1&#10;&#10;y=3x-3 Hope now it's obvious. Regards!

The function f(x)=58(1.6)x represents the possible bird population in a park x years from now. Each year, the expected number of
-BARSIC- [3]

Answer:

  1.6 times   or   60% more than

Step-by-step explanation:

The question seems to be asking about the growth factor in the given exponential function.

<h3>Exponential function</h3>

A generic exponential function will have the form ...

  quantity = (initial value) × (growth factor)^(number of intervals)

Comparing this form to the given formula ...

  f(x) = 58 × 1.6^x

we see the "growth factor" is 1.6. This is the multiplier from one interval (year) to the next.

Each year the expected number of birds is <u><em>1.6 times</em></u> the number the year before.

__

Additional comment

A <em>growth factor</em> is sometimes expressed in terms of a <em>growth rate</em>, usually a percentage.

  growth factor = 1 + growth rate

  1.6 = 1 + 0.60 = 1 + 60%

The growth rate of this bird population is 60% per year. Each year, the population is <u>60% more than</u> the year before.

Area of the triangle =[6 x (6√3) /2 ] / 2 ===>9√3=15.588

Area of each sector : (π/6). r² = π/6 x  9===.>4.712
And for the 3 sectors 3 x 4.712 =14.137
The shaded area is

15.588 - 14.137= 1.451

Order the values from least to greatest
melomori [17]
1.) -4 , -2 , 1 , 3 , |-5|

-4 and -2 are first because they are the least, then 1 and 3 are next. The absolute value of -5 is last because it has the greatest value, 5. (The absolute value of a negative number is the same number but positive)

2.) |8| , -5 , 0 , |-9| , 11

The absolute value if 8 is first because it has the least value, -8. (The absolute value of a positive number is the same number but negative) Then -5 and 0 are next. The absolute value of -9 is next because it is actually 9, and 11 is last because it has the greatest value.
