Step-by-step explanation:
Discriminant : k² - 4(12)(27) < 0
So k² - 1296 < 0, -36 < k < 36.
The answer is 145 divided by tan 65 degrees.
Since the equation for tangent is opposite/adjacent, you can just plug the numbers in.
tan(65)=145/x (x being the height that you are trying to find)
tan(65) * x = 145
Then divide tan(65) to isolate the x and you get:
145/tan(65)
Hope this helps!
I really dont know how to explain it but its (-2,-2)
To find your answer you could type in the cost and multiply it by the tax rate, so $0.72 X $0.06(The tax rate )= $0.0432
You then subtract 0.0432 from 0.72 and get 0.6768
rounded it would be $0.68
Hope this is right..
Hello wonderful person!!
Okay, so first of all, welcome to brainy
Second, you have to determine whether they are equal to each other and are the same. For example, if i say 2/4 is equal to 4/8, it's considered proportional.
Hope you understand this, and have a GREAT day!! :)
