Answer:
27 miles
Step-by-step explanation:
The law of cosines can be used to find the distance between the boats. In 1 hour, one has traveled 28 miles, and the other has traveled 26 miles. The angle between their directions of travel is ...
180° -50° -70° = 60°
Then the distance c can be found from ...
c^2 = a^2 +b^2 -2ab·cos(C)
c^2 = 28^2 +26^2 -2·28·26·cos(60°) = 732
c = √732 ≈ 27.055
The boats are 27 miles apart after 1 hour.
Answer:
78.54
Step-by-step explanation:
Area of a circle = A=πr2
A=π(5)2
A= 78.54
In order to graph this function you need to get axis of simmetry (by dividing the number with the squared x between the other number with the x), the vertex where the function changes its direction and the x and y axes cutting points.
Given:
Volume of rectangular prism: width * height * length
Surface area of rectangular prism : 2(wl + hl + lw)
A.
<span>8 ft by 5 ft by 6 ft; </span>⇒ <span>V = 240 ; S.A = 236</span>
5 ft by 6 ft by 8 ft; ⇒ V = 240 ; S.A = 236
B.
<span>8 ft by 5 ft by 6 ft; </span>⇒<span> V = 240 ; S.A. = 236</span>
10 ft by 8 ft by 3 ft ⇒ V = 240 ; S.A = 268
THIS IS THE ANSWER. SAME VOLUME: DIFFERENT SURFACE AREA.
C.
<span>15 ft by 8 ft by 2 ft; </span>⇒ <span>V = 240 ; S.A = 332</span>
6 ft by 4 ft by 15 ft ⇒ V = 360 ; S.A = 348
D.
<span>12 ft by 6 ft by 5 ft; </span>⇒<span> V = 360 ; SA = 324</span>
<span>8 ft by 10 ft by 3 ft </span>⇒ <span>V = 240 ; SA = 268 </span>
