Answer:
7x^2+10y^2-2x is the correct answer, Marcus put -10y INSTEAD of +10y^2
Step-by-step explanation:
(3x^2-2y^2+5x)+(4x^2+12y^2-7x)
Combine like terms- I'll add x^2 first, then y^2, and then finally x, and it will be in that order.
7x^2+10y^2-2x
Make sure to check your signs are correct, and you wrote down the proper exponents.
Answer:
b. -33
Step-by-step explanation:
The question is about finding the determinant of a 2×2 matrix
General formula; when given matrix A =[ b c ]
[ d e]
the determinant of A = (e×b)-(c×d)
Evaluate
(3 -3)
(-5 -6) = (-6×3) - ( -5×-3)
= (-18)- ( 15) = -33
In reference to the angle of elevation (41 degrees), the adjacent side is 60 and the opposite side is the unknown.
Using tangent ratio:
tan 41 = opp/60
60 tan41 = opp
opp side = 52.2yards
