The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
<u>Solution:</u>
Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.
The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.
If you wish to rent the canoe from 12:30 to 3:30 PM,
We have to write and solve a linear equation to find the total cost to rent the canoe.
Now, we know that,
<em>total cost = charges + rent fee
</em>
Let total cost be "c" and number of hours rented be "n"
Now, they used canoe from 12:30 to 3:30, which means 3 hours of time
So, put n = 3 in (1)
c = 6.5(3) + 25
c = 19.5 + 25
c = 43.5
Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
Answer:
9
Step-by-step explanation:
-3 x -1 = 3
6 + 3 = 9
Answer:
c) 21.2
Step-by-step explanation:
17.4 * 1.22 is approximately 21.2
Option B
Trevor isn't correct because -2i must also be a root
<em><u>Solution:</u></em>
For the polynomial with roots -7, 2i and 7 their roots can be,
1. ) Real roots
2.) Imaginary roots
The real roots are: -7 and +7
The imaginary root given is: 2i
The imaginary roots come from the square root. So they will be in form of
Therefore,
For f(x) with roots -7 and +7 and we have,
Fundamental Theorem of Algebra states that a polynomial will have exactly as many roots as its degree (the degree is the highest exponent of the polynomial).
So for f(x) with 4 roots, degree of f(x) is 4
So option B is correct. Trevor is not correct because –2i must also be a root.
Answer:
25
Step-by-step explanation:
Do 5 X times 15 = 75 x
Do 75x / 3 = 25
