The answer is:  " 100 cultures " .
_______________________________________________
   Take the number of the day we are at (from the beginning;  in this case, "9" (for "Day 9").
_________________________________________________
 Then add "1" to that number (in this case, " 9 + 1 = 10" .
_________________________________________________
Then, take that value (in this case, "10"); and "square" that value ; (in this case;  " 10² = 10 * 10 = 100 .   This is the answer.
__________________________________________________
The answer is:  " 100 cultures " .

Evaluate the expression for s = -15. -S= ​
Oxana [17]

Answer:

  -S = 15

Step-by-step explanation:

You are asked to find the opposite of the given value.

<h3>Opposite</h3>

The opposite of an integer value is obtained by changing its sign.

  S = -15

  -S = -(-15) = 15

__

<em>Additional comment</em>

Equivalently, you are multiplying by -1. The product of an even number of minus signs is a plus sign. We usually don't write the plus sign for a numerical value.

A rectangular deck is 12ft by 14ft. When the length and width are increased by the same amount, the area becomes 288sq. ft. By h
Cerrena [4.2K]

Dimensions of rectangle = 12 + x and 14 + x

(12 + x) (14 + x) = 288

 x^2 + 26x + 168 = 288

 x^2 + 26x - 120 = 0


(x + 30) (x - 4) = 0

x=-30, x =4

 since 4 is positive

 the dimensions increased by 4 feet

check the answer

12+4 = 16

14 +4 = 18

18*16 =288

Express the trigonometric function in terms of its positive acute reference angle. cos298° = cos
Nataly [62]
298* falls in quadrant 4 is 0* is the positive x-axis. In quadrant 4, cos is positive. Therefore, we simply need to calculate the acute angle,x, that correlates to 298*.

360 = 298 + x
62 = x

Therefore, we have :

cos(298*) = cos(62)

In case you need to know :

sin(298*) = - sin (62)
tan(298*) = - tan (62)

Since both sin and tan are negative in the fourth quadrant.
