Answer:
49 seconds
Step-by-step explanation:
The time perry used is 7/8 of a minute
a minute equals to 60 seconds
so the time perry used is 7/8 x 60 = 52.5 seconds
The winner used 14/15 of 52.5 seconds (perrys time)
so 14/15 x 52.5 = 49 seconds
The first answer is 0.38(x^2)-2.45x+5.1. first, on a graphing calculator, you enter the data in the chart into stat edit. then you turn on stat plot 1 and press graph. press stat calc quadreg to find the equation. then, substitute 9 in for x to find that there will be 13.83 thousand bacteria after 9 hours
The x-intercept of the linear equation is the value of x when y is equal to zero. From the given equation above,
y = 0.33x
When y is zero,
0 = 0.33x ; x = 0
When y is zero, x is also zero. This means that the school will not receive any amount when they are unable to sell anything.
