Arranging the given distances from sea level on the number line, we have;
- The error made by taking Egypt as being further from the sea level is assuming that the sea level is at the beginning (left) of the number line.
<h3>How can the number line be used to find the distance from the sea level?</h3>
The given elevation of the lowest points in the six countries are;
Country. Lowest point elevation (m)
China. →. -154
Egypt →. -133
Azerbaijan → -28
Serbia. →. 35
Israel. → -408
Laos. →. 70
Sorting the above countries from the country with the lowest point below sea level to the country with the highest point above sea level gives;
Israel → -408
China → -154
Egypt → -133
Azerbaijan → -28
Serbia. → 35
Laos. →. 70
On a number line, we have;
Israel < China < Egypt < Azerbaijan < Serbia < Laos
Relative to zero, which is the sea level, points -133 and -154 are located to the left of zero.
However, point -133 > -154, therefore, -154 < -133, the symbol < represents lesser (in this case 'lower') which indicates that China (point -154) is lower or further left from zero which is the sea level than Egypt (point -133).
The error is therefore mistaking the location of the sea level as being at the extreme left of the number line, rather than at the middle.

#SPJ1
Answer:
a) (0.555, 0) and (6, 0)
b) r = -3 and r = 1.8
c) (0.875, 0.676)
d) (0, 1.235)
Step-by-step explanation:
Set each term in the numerator and denominator equal to 0 and find r.
In the numerator:
r = 7/8, 5/9, or 6
In the denominator:
r = 9/5, 7/8, or -3
Zeros in the numerator that aren't in the denominator are r-intercepts.
Zeros in the denominator that aren't in the numerator are vertical asymptotes.
Zeros in both the numerator and the denominator are holes.
a) (0.555, 0) and (6, 0)
b) r = -3 and r = 1.8
c) Evaluate m(r) at r = 7/8. To do that, first divide out the common term (-8r + 7) from the numerator and denominator.
m(r) = (-9r+5)² (r−6)² / ( (-5r+9)² (r+3)² )
m(⅞) = (-9×⅞+5)² (⅞−6)² / ( (-5×⅞+9)² (⅞+3)² )
m(⅞) = (-23/8)² (-41/8)² / ( (37/8)² (31/8)² )
m(⅞) = (-23)² (-41)² / ( (37)² (31)² )
m(⅞) = 0.676
The hole is at (0.875, 0.676).
d) Evaluate m(r) at r = 0.
m(0) = (-9×0+5)² (0−6)² / ( (-5×0+9)² (0+3)² )
m(0) = (5)² (-6)² / ( (9)² (3)² )
m(0) = 1.235
The m(r)-intercept is (0, 1.235).
Answer:
12
Step-by-step explanation:
1. C) The amount that something can hold. Usually means volume, such as milliliters (ml) or liters (l) in Metric, or pints or gallons in Imperial.
It is the amount something can hold.
Answer:
A quadratic Trinomial
Step-by-step explanation:
hope this helps
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
