-(a-b)(a-bc) if a=3 b=-4 and c=2

Mathematics

Oxana [17]3 years ago

Answer:

-77

Step-by-step explanation:

Simply plug in: -(3-(-4))(3-(-4)(2))

Because the "-" sign is outside the parentheses, you would distribute.

It would then be: -3-4. *positive and negative=negative, negative and negative=positive. -3-4=-7. It would then be: (-7) · ((3-(-4)(2))

(-4)(2)=-8. →(3-(-8))=(3+8)=11. The equation would then be: (-7) · (11)= -77

A ship is sailing due north. At a certain point the bearing of a lighthouse is N 42.8∘E and the distance is 10.5. After a while,
bija089 [108]

Answer:

How far did the ship travel between the two observations of the lighthouse  = 9.29

Step-by-step explanation:

the first step to answer this question is drawing the illustration as the attachment.

P is the ship, R is the light house and Q is the bearing.

PR is the distance between the ship and the light house, PR = 10.5

∠P = 42.8°, ∠Q = 59.7°

Thus, ∠R = 180° - ∠P  - ∠Q

               = 180° - 42.8°- 59.7°

               = 77.5°

PQ is the the distance of the ship moving. We can use the sinus equation

\frac{PR}{sin R} = \frac{PQ}{sin Q}

\frac{10.5}{sin 77.5°} = \frac{PQ}{sin 59.7°}

PQ = (\frac{10.5}{Sin 77.5°})(sin 59.7°)

     = 9.29
