Can you post the image of the question?
So there for i can help
Answer:
There could be 0, 2, or 4 complex solutions
Step-by-step explanation:
The Fundamental Theorem of Algebra states that any polynomial with n degree will have n solutions So since the degree of the polynomial you provided has a degree of 4, that means there are 4 possible solutions. This question specifically asks for complex zeroes. Complex zeroes come in conjugate pairs, so that means if you have one complex zero, there is another complex zero which is it's conjugate. For this reason, there can only be an even number of complex zeroes. And since there's 4 possible solutions, There could be 0, 2, or 4 complex solutions
Answer:
3 boxes of fertilisers.
Solving steps:
<u>Part A</u>:
Area of the garden, rectangle:
Length * Width
12 * 7
84 m²
Area of patio:


m²
Area of grass:
Area of the garden - Area of patio
84 m² - 9 m²
75 m²
<u>Part B</u>:
32 m² ↔ 1 box
1 m² ↔
box
75 m² ↔
boxes
75 m² ↔ 2.34375 boxes
- As she cannot buy exact 2.34375 boxes.
She should buy 3 boxes of fertilisers.
Now the aim of the above discussion is to internalize the mathematical relationships for open-end air columns in order to perform calculations predicting the length of air column required to produce a given natural frequency. And conversely, calculations can be performed to predict the natural frequencies produced by a known length of air column. Each of these calculations requires knowledge of the speed of a wave in air (which is approximately 340 m/s at room temperatures). The graphic below depicts the relationships between the key variables in such calculations. These relationships will be used to assist in the solution to problems involving standing waves in musical instruments.
