Answer:
-40
Step-by-step explanation:
f(10)=-4(10)
f(10)=-40
Step-by-step explanation:
Distance = rate × time
If B is the rate of the boat, and C is the rate of the current, then we can write two equations:
18 = (B + C) × 3
18 = (B − C) × 9
Simplifying the equations:
6 = B + C
2 = B − C
Add the equations together to eliminate C:
8 = 2B
B = 4
Plug into either equation to find C:
C = 2
The boat's rate is 4 mph, and the current's rate is 2 mph.
Answer:
960
Step-by-step explanation:
(if i made any typos, sorry it is kind of hard to type on computer over writing on paper.)
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=(a+b+c)/2
Solving forA
A=ah+bh+ch+1/2 sqrt(﹣a^4+2(ab)^2+2(ac)^2﹣b4+2(bc)^2﹣c^4)=10·12+24·12+26·12+1
2·﹣104+2·(10·24)2+2·(10·26)2﹣244+2·(24·26)2﹣264=960
Answer:
Both plans cost the same when 50 texts are sent
Step-by-step explanation:
The cost of sending 50 texts in the same for both plans from the graph because it will cost $22.50
Hiroto's plan will cost less than Emilia's plan when more than 50 texts are sent.For example the cost of sending 60 texts for Hiroto's plan will be around $23 where as that for Emilia's plan will cost about $25
For 22 texts the cost will be more for Hiroto's plan than Emilia's.
For more than 22 texts both plans will cost the same at 50 texts.
