Answer:k/22 =-66
k=-1,452
Step-by-step explanation:
A.
-1:
(-1,1)
0:
(0, 2)
1:
(1, 4)
2:
(2, 8)
3:
(3,16)b.
To graph the equation, simply go through the points (-2, 0.5), (-1, 1), (0,2), (1,4), (2,8), and (3,16). Make sure you never go below 0 on the x-axis, because there's an asymptote there.
Hope this helps!
Exponential function
form of interest rates
P(1 + r)^x
where p is the prime and r is rate of change and x is time in years
3000(1 + 4%)^1
The answer would be
3000(1.04)^1 = 3120 Euros
Answer:
x has no real solution
Step-by-step explanation:
Our equation is qudratic equation so the method we will follow to solve it is using the dicriminant :
- Let Δ be the dicriminant
- a=1
- b=2
- c=9
- Δ= 2²-4*1*9 =4-36=-32
- we notice that Δ≤0⇒x has no real solution
<h2>Solution (a) :-</h2>
Let the cost of the less expensive comic book be x .
Then :-

Using this equation , we can find the cost of the less expensive comic book .
Price of the less expensive book :-





Cost of the less expensive book is 107 .
Therefore , the epice of the less expensive book = $ 107 .
<h2>Solution (b) :-</h2>
Cost of the more expensive book = 11x
Which means :-






Therefore , the price of the more expensive book = $ 1177 .
