Answer:
The sum of the given vectors is
Step-by-step explanation:
For the given vectors (which are R³ vectors), the sum is simply the sum of each coordinate, if a general vector is written as
<u>the sum of two vector will be in each coordinate at a time</u>.
To illustrate geometrically the resulting vector in the space xyz
<em>we can say that the first coordinate is on the x-axis, the sencond on the y-axis, and the third one on the z-axis</em>, so the illustration will be a <em>vector starting from the center of coordinates, and ending in the coordinates 0 of the x-axis, 1 of the y-axis, and -1 of the z-axis</em>. <u>Or, in a plane yz (where x=0), a vector from the origin to the point 1 in y-axis, and -1 in z-axis</u>.
Answer:
177
Step-by-step explanation:
This scenario can be modeled as an <u>exponential function</u>.
General form of an exponential function:
where:
- a is the initial value (y-intercept)
- b is the base (growth/decay factor) in decimal form
- x is the independent variable
- y is the dependent variable
If b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
If the number of trees <u>increase</u> by <u>10% each year</u>, then the number of trees each year will be 110% of the number of trees the previous year. Therefore, the <u>growth factor is 110%</u>.
Given:
- a = 100 trees
- b = 110% = 1.10 (in decimal form)
- x = time (in years)
- y = number of trees in the orchard
Substituting the given values into the function:
(where x is time in years and y is the number of trees in the orchard)
To find how many trees are in the orchard in the 6th year, input x = 6 into the found equation:
Therefore, Martin had 177 trees in his orchard in the sixth year.
