18 is 60 percent of 30. 3 percent is 10 percent of 30 so 3 x 6 equals 18.
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
Answer:
A = 1.5 π in² ≈ 4.7 in²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 3² × 
= 9π ×
= 1.5π in²
≈ 4.7 in² ( to the nearest tenth )
Answer:
$200
Step-by-step explanation:
To find Jeff's net worth, we will deduct all his debts (liabilities) from his assets (his properties).
ASSETS
Savings Account - $6000
Investments - $15000
Guitar - $1000
TOTAL - $22000
LIABILITIES
Student loans - $17000
Credit Card Debt - $1200
Outstanding car payment - $3600
TOTAL - $21800
NET WORTH = Assets - Liabilities
NW = $22000 - $21800
NW = $200
His net worth is $200.
