Step-by-step explanation:
The answer is 6hours in 122 minutes do umknow
Answer:
240 ft squared
Step-by-step explanation:
there are 3 rectangles so l*w for each of them
(12*6)+(13+6)+(5*6)
72+78+30
sa of a triangle is b*h divided by 2
5*12 divided by 2=30
there are two equal triangles so
180+30+30=240
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The amount charge per year is 
The number of members it will have at this amount is 
The amount amount increase that will lead to the loss of a single member is 
Generally the total amount the club would obtain from its members is mathematically represented as

Now let x denote the number of member lost
Hence

=> 
=> 
Thus the number of members that be removed to give the maximum income from dues is obtained by differentiating the above equation and equating it to zero

=> 
So from
we have


So the amount the club should charge is


X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
