There are 12 inches in a foot, so 9ft = 108in. Also, 80% = 0.8. Therefore the formula is:
h(n) = 108 * 0.8^n.
To find the bounce height after 10 bounces, substitute n=10 into the equation:
h(n) = 108 * 0.8^10 = 11.60in (2.d.p.).
Finally to find how many bounces happen before the height is less than one inch, substitute h(n) = 1, then rearrage with logarithms to solve for the power, x:
108 * 0.8^x = 1;
0.8^x = 1/108;
Ln(0.8^x) = ln(1/108);
xln(0.8) = ln(1\108);
x = ln(1/108) / ln(0.8) = -4.682 / -0.223 = 21 bounces
60 and x are alternate interior angles, meaning they are equal to each other. Since the angle on the left is split into two, that means x + 25° = 60. That means you are correct, x + 35° :).
Answer:
Step-by-step explanation:
So you first pretend they were all the general admission tickets which is
450x6.50$=2925$ So the number is 4237.50$-2925$=1312.50$ away from the actual price. The price difference between the two is 10.00$-6.50$= 3.50$
Then you put the total price difference 1312.50$ and divide by 3.50$ then you get the amount of upper box tickets. 1312.50$/3.50$=375( Amount of Upper box. So now you know how many upper box were bought. You take it away from 450 tickets sold. 450-375=75
375x10=3750$
75x6.5=487.5$
3750$+487.5$=4237.5$
Hope that helped you!
