Answer:
<h3>after 2 secs</h3>
Step-by-step explanation:
The paths crossed at when the height are equal i.e when f(x) = g(x)
Given
f(x)=−x^2+2x+4
g(x) = 2x
IF f(x) = g(x), then;
−x^2+2x+4 = 2x
−x^2+2x+4 - 2x = 0
−x^2+4 = 0
-x^2 = -4
x^2 = 4
x = ±√4
x = 2 and -2
Time cannot be negative
Hence x = 2
The path crossed after 2 seconds

Step-by-step explanation:
troll!!!!!!!!!!!!!!!!!!!!!!
The total amount that was raised for charity is £75.
<h3>What is the total amount raised?</h3>
Here is the sample space
1 2 3 4 5 6
Heads 1 4 9 16 25 36
Tails 1 8 27 64 125 216
Probability of getting a number greater than 30 = 4/12 = 1/3
1/3 x 450 = 150
Total value of people getting more than 30 : 150 x £1 = £150
Total amount paid = 50 x 450 = £225
Amount raised = £225 - 150 = £75

The slope of the graph would be a positive slope
The picture in the attached figure
we know that
The inscribed angle measures half of the arc it comprises
so
∠ GHL=(1/2)*[arc LI]
∠ GHL=32°
32°=(1/2)*arc LI
arc LI=32°*2-------> arc LI=64°
∠KLI=(1/2)*[arc LI]-----> ∠KLI=(1/2)*64°-----> ∠KLI=32°
the answer is the option<span>
B. KLI= 32LI=64</span>
