Say it in english so i cant try to help
The answer to this question is 10 cm
In this question, you asked the height and given the volume of water(2400cm3), aquarium length(20cm), and aquarium width(12cm).
Then you need to divide the volume with the length and width. The equation would be:
Aquarium height= volume / length / width
Aquarium height= 2400 cm3 / 20cm / 12 cm = 10cm.
To find the sum of two numbers, we must add them together. However, in this case we are adding a negative number. Addition of a negative number can also be written as subtraction, and this method is easier for most people to compute and understand, so we are going to rewrite the expression as follows:
3 - 6
Next, we must just perform the subtraction.
3 - 6 = -3
Therefore, your answer is -3.
Hope this helps!
Answer:
See explanation
Step-by-step explanation:
The range of the cosine function is 
Therefore 
is not defined.
Assuming your question is rather 
Then 
in the second quadrant.
Formula for distance between two points is
d∧2=(x2-x1)∧2+(y2-y1)∧2 in our case (x1,y1)=(k,q) and (x2,y2)=(0,0)
d∧2=(0-k)∧2+(0-q)∧2= k∧2+q∧2 => d=√(k∧2+q∧2)
Good luck!!!
