Answer:
This is not a triangle
Step-by-step explanation:
If you use the triangle inequality theorem you can reach your answer.
The theorem states that if you add the length of any 2 sides together, you will have a length greater than the length of the other side. Using this method we can easily see that 7+6=13 which is less than 21. Meaning this is not a triangle
Answer:
Step-by-step explanation:
"Find the values of x that satisfy 3x - 2x^2 = 7." Please do not use " × " to represent a variable; " × " is an operator, the "multiply" operator.
Rearrange these three terms in descending order by powers of x:
-2x^2 + 3x - 7 = 0. Here the coefficients are a = -2, b = 3 and c = -7, and so the discriminant of this quadratic is b^2-4ac, or 9 - 4(-2)(-7), or 9 - 56, or -47.
Because the discriminant is negative, we'll have two different complex roots here. The quadratic formula becomes
-3 ± i√47 -3 ± i√47
x = ----------------- = -------------------
2(-2) -4
Answer:
Common ratio r = 2
Step-by-step explanation:
the fith term of a G.P is 8 times the 2nd term.
Hence, common ratio is 2.
Answer:
35 ml/hr
Step-by-step explanation:
Convert lbs to kg
205 ÷ 2.2 = 93.18 = 93.2 kg
Calculate the minute rate
93.2 kg x 5 mcg/kg/min = 466 mcg/min
Calculate hourly rate
466 mcg/min x 60 mins/hr = 27,960 mcg/hr
Drug is expressed in mg, so convert mcg to mg
27,960 mcg = 27.96 mg
Answer:
44
Step-by-step explanation:
All interior angles of any triangle add up to 180
