When an exponential function is given as
f(x)=ab^x, and
knowing that b^0=1, that means that
f(0)=ab^0=a value of function when x=0, or the initial value.
In the case of
f(x)=20.b^x, f(0)=20.b^0 = 20 (initial value)
If b=1.2, then the hourly growth rate is (1.2-1)=0.2=20%.
If b=1.85, then the hourly growth rate is (1.85-1)=0.85=85%.
3.6 * 10^(-3) is the scientific notation
Answer:
subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.
Step-by-step explanation:
-3x + 2.4 = 19.2
v <u>-2.4</u> <u>-2.4</u>
v 0 16.8
<u>-3x</u>=<u>16.8</u>
-3 -3
x=-5.6

The figure depicting the board game is attached below.
Answer:
Step-by-step explanation:
Kindly note that selections done without replacement.
Count of numbers on the board game = 8
Count of odd numbers = (1, 9, 1) = 3
Count of digit 6 = 3
Probability = required outcome / Total possible outcomes
P(picking an odd number) = 3 / 8
Without replacement
Numbers left on board game = 8 - 1 = 7
P(picking a 6) = 3 / 7
Hence,
P(picking an odd number then, a 6) = 3/8 * 3/7 = 9 / 56
Answer:
5x - 2y = - 2
Step-by-step explanation:
Given the 2 equations
- 2x + y = 0 → (1)
- 7x + 3y = 2 → (2)
Subtracting (2) from (1) term by term
- 2x - (- 7x) + y - 3y = 0 - 2, that is
- 2x + 7x - 2y = - 2
5x - 2y = - 2
