Answer:
x = 2i, x = -2i and x = 4 are the roots of given polynomial.
Step-by-step explanation:
We are given the following expression in the question:

One of the zeroes of the above polynomial is 2i, that is :

Thus, we can write

Now, we check if -2i is a root of the given polynomial:

Thus, we can write

Therefore,

Dividing the given polynomial:

Thus,

X = 4 is a root of the given polynomial.

Thus, 2i, -2i and 4 are the roots of given polynomial.
Answer:
Uneffected.
Step-by-step explanation:
The order of the numbers doesn't affect the product in multiplication problems.
For example, we need to multiply 2 × 10.
We can write it as : 2×5×2
2×(5×2) = 2×10 = 20
Also,
(2×5)×2 = 10×2 = 20
Hence, it will remain unaffected when we multiply numbers.

Answer:
24.6967 meters
Step-by-step explanation:
The roots of the tree go 6 and 5 over 12 meters below the ground level.
Now, 6 and 5 over 12 meters is equivalent to 6.4167 meters.
Again the top of the tree is 18.28 meters high from the ground level.
Therefore, the total height of the tree from the bottom of the root to the top is
(6.4167 +18.28) = 24.6967 meters (Answer)
Answer: $110
Step-by-step explanation:
Given: At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.
F(d)models the fee (in dollars) for climbing d meters.

To find the initial amount, substitute d=0 int the above function, we get

Hence, the initial fee= $110.
