put your finger on zero and move it to -1 then go up to positive 1 and put ur dot there.
put ur finger on 0 again then go to -1 but now u move down to -2 and put ur dot there.
now put ur finger on the zero and go to the opposite side to positive 2 then go down to -2 and put ur dot there. Hope that helps :)

A strobe light is located at the center of a square dance room. the rotating light is 40 feet from each of the square walls and

Effectus [21]

The equation of the rotating light is an illustration of a secant function

The equation that represents the distance between the center of the circle and the light source is $d(t) = 40\sec(\frac{\pi}{3}t)$

<h3>How to determine the equation</h3>

The equation is a secant function represented by

$y =A\sec(Bt)$

Where:

A represents the amplitude

So, we have:

$A = 40$ --- the distance of the light from each square wall

B represents the period, and it is calculated as:

$B = \frac{2\pi}{T}$

The light completes its full rotation every 6 seconds.

This means that,

T = 6

So, we have:

$B = \frac{2\pi}{6}$

Simplify

$B = \frac{\pi}{3}$

Substitute values for A and B in $y =A\sec(Bt)$

$y = 40\sec(\frac{\pi}{3}t)$

Rewrite as a function

$d(t) = 40\sec(\frac{\pi}{3}t)$

Hence, the equation that represents the distance between the center of the circle and the light source is $d(t) = 40\sec(\frac{\pi}{3}t)$

Write an expression with a variable m, a coefficient -3, and a constant of 17

Svetlanka [38]

Answer

-3m + 17

Step-by-step explanation:

A coefficient is a number that goes in front of the variable, so -3 would go in front of m. A constant is just a number on it's own, so it would be +17

Factor the GCF: -6x^4y^5 - 15x^3y^2 + 9x^2y^3

natta225 [31]

<span>-6x^4y^5 - 15x^3y^2 + 9x^2y^3

</span>-6x^4y^5 = -2, 3, x, x, x, x, y, y, y, y, y
15x^3y^2 = -5, 3 x, x, x, y, y
9x^2y^3 = 3, 3 x, x, y, y, y

Each group has a 3 in common and each group has 2 x in common and each group has 2 y in common so the GCF = -3x^2y^2

Divide that out and we get
$\frac{-6x^4y^5 - 15x^3y^2 + 9x^2y^3}{-3x^2y^2} =$
$2x^2y^3 + 5x - 3y$
$-3x^2y^2(2x^2y^3 + 5x - 3y)$

What is 44/12 as a simplified mixed fraction

Marat540 [252]

3 67/100

3 will stay a whole number so you put that as the whole number. 67 is 67 percent of a whole. so you put it over 100.

WILL GIVE BRAINLIEST write an equation for the nth term of the arithmetic sequence and find the 30th term 28, 25, 22, 19, ... (s

ryzh [129]

Answer: 31 - 3n

Step-by-step explanation:

step one:

25 - 28 = -3

22 - 25 = -3

19 - 22 = -3

d = -3

Step two:

An = a1 + (n-1) d

= 28 + (n-1) -3

= 28 - 3n + 3

= 31 - 3n

a1= 28 d = 3
