Answer:
The correct option is C.
C) ellipse, -30°
Step-by-step explanation:
General form of equation for a conic section is:
(A)x² + (B)xy + (C)y² + (D)x + (E)y + F = 0
The equation of the conic section is given:
21x² - (8√3)xy + 13y² = 225
21x² - (8√3)xy + 13y² - 225 = 0
Which can be rewritten as:
(21)x² + (-8√3)xy + (13)y² + (0)x + (0)y + (-225) = 0
where
A = 21
B = -8√3
C = 13
D = 0
E = 0
F = -225
Consult the table below.
As A ≠ C and and AC > 0 , the equation represents an ellipse
The angle of rotation can be found by following equation:
cot(2θ) = (A - C)/B
cot(2θ) = (21 - 13)/(-8√3)
2θ = cot⁻¹(8/-8√3)
2θ = 120°
θ = 60° (from x-axis)
As the major axis of ellipse lies on y-axis, axis of rotation from y-axis is
θ = -30°
14+30=44 (from his head to his waist)
76-44=32(he is 76 inch tall so substract 44 from 76 to find the length of feet-waist)
answer is 32
Answer:
Physical trait is phenotype
Looking at a dog will obviously also give the phenotype
And the last one is A
Because considering G is for green and g is for yellow, the results of crossing GG and gg will all give GG that is the green scale dominant so all will have green. Since yellow isn't even expressed it's impossible for yellow to be Co dominant thus leaving us with A.

Answer:
Since the 4th root of 50 is 50^1/4, and (50^1/4)^4=1, raising the 4th root of 50 to the 4th power cancels the root and the power.
Step-by-step explanation:
The root of a term is the 1/(that number) version of that term. Therefore, something that is a 4th root, must be that number raised to 1/4
