Answer:
About $78
Step-by-step explanation:
The company is not complete. The question is to estimate the sales 8 weeks after release. To do that, we will substitute t = 8 into the modeled function s=10√5t+15
s = 10√5(8) + 15
s = 10√40 + 15
s =10(6.32)+15
s = 63.2+15
s = 78.2
Hence the sales after 8weeks is about $78.
2x+3x+5x=90
10x=90
x=9
2 times 9=18
3 times 9=27
5 times 9=45
$18, $27, and $45.
The question is also the same as asking what is the x value of the solution of the two functions graphed above. The solution is the point where these lines intersect. So, from the choices, the correct answer would be the second option. The input value that <span>produces the same output value for the two functions on the graph would be x=-2. Hope this answers the question.</span>
