Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:
So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.
Answer:
20 x 10
Step-by-step explanation:
because these are the remaining digits :D
Answer:
Step-by-step explanation:
4). This is an exponential function.
5). Let the equation of this function is,
f(x) = a(b)ˣ
Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,
For (-1, 4),
4 = a(b)⁻¹
4 = 
--------(1)
For (0, 6),
6 = a(b)⁰
a = 6
From equation (1),
4 = 
b = 
= 1.5
Therefore, equation of the function will be,
f(x) = 6(1.5)ˣ
6). Now the value of f(-4) will be,
f(-4) = 6(1.5)⁻⁴
= 1.185
Answer:
(2;-5) and (0;-4).
Step-by-step explanation:
if the given graph is the same as in the attached picture (y=-0.5x-4), then two points only belong to it.
Answer:
14 spotted socks
Step-by-step explanation:
Sam has 3 units of striped socks and 6 of them.
Find one unit.
3 units = 6
1 unit = 6 ÷ 3 = 2
Sam has 7 units of spotted socks.
7 units = 2 x 7 = 14
