Answer:
Just learned this-
They are both 1 because of it being to the power of zero and if you type the both in like...
Step-by-step explanation:
sin(73)^0 you get 1
tan(12)^0 you get 1
Substitute.
2x+(2x -15) = -3
4x -15 = -3
Add 15 to both sides
4x = 12
Divide by 4
X=3
2(3) + y = -3
6+y=-3
-6 from both sides
Y=-9
(3,-9)
Answer:

Step-by-step explanation:
Given




Required
The perimeter
To do this, we first calculate the side lengths using distance formula

So, we have:








The perimeter is:



Answer:
$27.87
Step-by-step explanation:
if it is 1 by 2 you would multiply 1 x 2 and get 2 then multiply 13.87 x 2 to get 27.87 and it leaves you with $27.87
In the case that a scientist cools three gases in an experiment, the change in temperature will be negative for the experiment. This is because cooling results in a temperature lower than the original temperature. For example, a gas originally at 25°C when cooled to 20°C has a temperature change of -5°C.
