Answer:
Option C.
Step-by-step explanation:
We know that
f(t) = 1.5t + 50
represents the approximate population of trout in Sky Lake
And
g(t) = 0.1t^2 - 4t + 70
represents the approximate population of trout in Lake Cyan
The total trout population in the area is described as
f(t) + g(t)
f(t) + g(t) = [1.5t + 50] + [0.1t^2 - 4t + 70]
f(t) + g(t) = [1.5t + 50+ 0.1t^2 - 4t + 70]
f(t) + g(t) = [0.1t^2 -2.5t + 120]
f(t) + g(t) = 0.1t^2 -2.5t + 120
Option C.
Answer:
y= -5/3 + 5
Step-by-step explanation:
5x-3y=15 first move the 5x to the right side of the equation which becomes 3y= -5x +15 and then divide the whole equation by 3 because u want y to be on its own so then the answer is y= -5/3 + 5
Answer:
S1=9.905 cubic units
Step-by-step explanation:
As the two solids are congruent it can be said that they have the same angles and the same lengths then their volume is equal and therefore S1= S2 then S1∪S2= S1+S2- S1∩S2 = S1+S1- S1∩S2 =2S1- S1∩S2 =25.
Now, S1∩ S2= Prism volume= (Area of triangle (A)*Height(h)), the area of the equilateral triangle that is the base of the prism is given by A=√3/4*(length Lateral) ^2= A=√3/4*(2^2 )=√3 square units .
Then S1∩ S2=A*h =√3*3=5. 19 cubic units .
Finally you have
2S1- S1∩S2 =25
2S1-5. 19=25 clearing s1 you have
S1=(25-5. 19)/2 = 9. 905 cubic units

Answer:
the best i can do is give you an equation
Step-by-step explanation:
y=0.05x+50 for plan A
y-0.15+5 for plan B. You didnt give much to work off or really ask a question
