Answer:
75%
Step-by-step explanation:
Here, we are asked to calculate the percentage of a trip that has been completed by Leigh.
Firstly, we identify the total length of the trip, this is 1470km. She stopped 370km from her destination. The length of the distance traveled is 1470km - 370km = 1100km
Now we proceed to calculate what percentage of the journey is this.
We calculate this by placing it over the total length multiplied by 100%
That would be
1100/1470 * 100 = 74.82 approximately 75%
Interfere are numbers that can be neagative
Or positive. Rational numbers are numbers that can be put into fractions. Irrational numbers cannot be put into a fraction
Zero slope is y=#
ex. y=5 or y=127 It can be any number
It would be a horizontal line
Undefined slope is x=#
ex. x=22 or x=1 Again it can be any number
It would be a vertical line

Question:</h2>
A surveyor is estimating the distance across a river. The actual distance is 284.5 m. The surveyor's estimate is 300 m. Find the absolute error and the percent error of the surveyor's estimate. If necessary, round your answers to the nearest tenth.
<h2>
Answer:</h2>
(i) Absolute error = 15.5m
(ii) Percent error = 5.5%
<h2>
Step-by-step explanation:</h2>
<em>Given:</em>
Actual measurement of the distance = 284.5 m
Estimated measurement of the distance by the surveyor = 300 m
(i) The absolute error is the magnitude of the difference between the estimated value measured by the surveyor and the actual value of the distance across the river.
i.e
Absolute error = | estimated value - actual value |
Absolute error = | 300m - 284.5m | = 15.5m
(ii) The percent error (% error) is given by the ratio of the absolute error to the actual value then multiplied by 100%. i.e
% error = x 100%
% error = x 100%
% error = 0.05448 x 100%
% error = 5.448%
% error = 5.5% [to the nearest tenth]
Answer:
neither
Step-by-step explanation:
First differences are 3, 5, 7, 9, and the differences of these (2nd differences) are constant at 2. The degree of the polynomial function describing the sequence is equal to the number of the differences that are constant. Here, that is 2nd differences, so the sequences is described by a 2nd-degree (quadratic) polynomial.
It is not linear (arithmetic) or exponential (first differences have a common ratio).
