Answer:
C $320
Step-by-step explanation:
write equations for the two possible choices
situation 1:
y₁ = 20 + 0.5x, where y is the total price the club pays and x is the sales
** note i use 0.5 instead of 50, since 50 would represent 5000%
y₂ = 100 + 0.25x, where y is the total price the club pays and x is the sales
now set the two equations equal to each other
20 + 0.5x = 100 + 0.25x
isolate x by subtracting 0.25x and 20 from each side
20 + 0.5x - 0.25x - 20 = 100 + 0.25x -0.25x -20
0.25x = 80
divide both sides by 0.25
=
x = 320
Wouldnt it be 21 idk dont pay attention to me lol
40
substitute t = 10 into the expression
4t² = 4 × 10² = 4 × 100 = 400
now divide by 10 → = 40
Given:
The function is:
To find:
The all the real and non-real roots of the given function.
Solution:
We have,
For roots, ,
Taking square root on both sides, we get
The roots of the given function are -7i and 7i.
Therefore, the correct option is B.
