Answer:
Below.
Step-by-step explanation:
That will be the angle whose tangent is 45/29
That is 57.2 degrees.
# 3 is .4 because u multiply .2*.2
Find the common denominator first--> 10
1/2= ?/10 ?=5
so 5/10 +9/10 (Now you just add the numerators and keep the common denominator the same)
14/10 and if you want to simplify it, simply divide both the top and bottom by 2
answer = 7/5
Answer:
4 or 3.75
Step-by-step explanation:
there are 16 cups in a gallon
60/16 is 3.75
if you want you can round up
but to have an even amount it would be 4
If you write in standard form for a quadratic: ax^2+bx+c. The discriminant is b^2-4ac, so given -1=5x^2-2x, or 5x^2-2x+1=0, the discriminant is 4-4(5)(1)=-16. The discriminant is used to give information about the roots (a.k.a. zero or solution) of a quadratic. If it's positive, it means that the quadratic has 2 real roots. If it's 0, it has a double root. And, if it's negative, like in this question, it has no real roots.
EXTRA
If you want to know where the discriminant comes from, it is derived from the quadratic formula, which is a more straightforward method of finding roots.
