Answers:
(2) Option (B) 4
(3) The answer is: +1
Explanations:
(2) The plus sign in the limit indicates that it is the right hand limit. So we have to approach to 2 from the right side of the graph. When we do that, we see the value of y = +4. Hence the correct option is (B) 4
NOTE: Although the question seems complex because there is slope involved but in this particular case, the examiner is concerned about the right hand limit.
(3) The minus sign in the limit indicates that it is the left hand limit. So we have to approach to 3 from the left side of the graph. When we do that, we see the value of y = +1. Hence the correct answer is +1.
Answer:
No
Step-by-step explanation:
square root of 50 is not a whole number, or even a rational number. It is an irrational number, but you can simplify it or find rational approximations for it.
The answer would b the 3rd option
Answer:
A,B,C, and E
Step-by-step explanation:
Answer:
21. The slope is 50.
22. 0
23. y=50x
24. $2600
Step-by-step explanation:
21. The slope of the line is 50. Slope is defined as "rise over run". As the line increases, each segment moves up the y-axis by $50, and to the right on the x-axis 1 segment. (Work: 50 divided by 1)
22. The y-intercept is (0, 0), or simply 0. If you look at the graph you can see that the line crosses the y-axis at the origin. This makes the y-intercept equal to 0.
23. The slope tells you that the student makes $50 every week. The y-intercept is 0. Using the formula y=mx+b, an appropriate equation would be y=50x.
24. The equation found in problem 23 can me used to determine how much a student makes (y) after "x" weeks. Substitute 52 for x to solve for y. This becomes y=50(52). This can be simplified to y=2600. This means that after 52 weeks, the student will have made $2,600.
