Use Pythagorean theorem to find BC
AB^2 + BC^2 = AC^2
6^2 + BC^2 = 10^2
36 + BC^2 = 100
BC^2 = 64
BC = 8

If AC = 10, CD and AD = 5
Tan = opp/adj
Tan = 5/8

Triangle BCD is a 45-45-90 triangle
CD = BD = 5
Sec = inverse cos
sec = hyp/adj

A=4,b=-2,C=5 d=-6 , e =-1 5 ed-3cb +4ba-2ea​
Alecsey [184]

Answer:

208

Step-by-step explanation:

{ed}-{3cb}+{4ba}-{2ea} = {(-15)*(-6)} - {3*5*(-2)} + {4*(-2)*4} - {2*(-15)*4}

={90} - {15*(-2)} + {16*(-2)} - {8*(-15)}

= {90} - {-30} + {-32} - {-120}

= 90 (--)30 (+-) 32 (--) 120

= 90 + 30 - 32 + 120

= 120 - 32 + 120

= 88 + 120

= 208

I'm having a little bit of trouble figuring out the formula to solve this problem.
goldfiish [28.3K]

Answer:Red price hast he least least cost per gram of apple.

Step-by-step explanation:

1) considering Royal Gala, 75 gram apple cost $0.41

The cost per gram is 0.41/75 = $0.0055

2) considering Honey crisp, 93 gram apple cost $0.82

The cost per gram is 0.82/93 = $0.0088

3) considering Red Prince, 81 gram apple cost $0.36

The cost per gram is 0.36/81 = $0.0044

Since $0.0044 per gram is the lowest of the three, then the type of apple with the least cost per gram is Red prince.
