Answer:
AB = 5.6 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 62°
Hypothenus = BC = 12 cm
Adjacent = AB =?
The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:
Cos θ = Adjacent / Hypothenus
Cos 62 = AB / 12
0.4695 = AB / 12
Cross multiply
AB = 0.4695 × 12
AB = 5.6 cm
Thus, length AB is 5.6 cm
It will take Mary 6 1/4 hours to walk 25 miles at this rate.
Divide the total number of miles by the number of miles per hour.
25/4 hours
This fraction cannot be simplified, but it can become a mixed number.
6 1/4 hours
the correct answer is A) 10x + 30
Answer:
List is {-2i, 2i, -4)
Step-by-step explanation:
This is a third order polynomial, so we expect three roots (solutions).
Note that we can factor this expression by grouping:
(x²)(x + 4) + (4)(x + 4) = 0, or
(x + 4)(x² + 4) = 0
The factor (x + 4) corresponds to the root/solution x = -4, and:
The other factor (x² + 4) corresponds to the roots/solutions x = 2i and x = -2i.
List is {-2i, 2i, -4)
It would be c because you would add (5+9) to get 14 and then multiple it by 8. So 8(14) but that’s the answer if it just wants you to rewrite it
The answer is 112 if they want you to solve it
