Sam picks corn on his uncle's farm. His uncle pays him $0.40 per basket for the first 50 baskets of corn that he picks in a day and $0.50 per basket for all baskets picked over 50. On Friday Sam picked 120 baskets of corn. How much did he earn?
Answer:
$55
Step-by-step explanation:
Find out the number of baskets paid at $0.5/basket:
Since the first 50 are paid for $0.4, and he picked 130 baskets, we can subtract 50 from 120, giving us 70.
Finding the amount paid at $0.4/basket:
50*$0.4 = $20
Finding the amount paid at $0.5/basket:
70*$0.5 = $35
Total = $55

If , what is the truncation error for S3? 0.610 0.774 1.476 1.640
ANSWER: D
Answer:
D
Step-by-step explanation:
Unit Test Review
The truncation error for S3 is 1.640
The correct option is (D)
What is Truncation error?Truncation error is the difference between a truncated value and the actual value.
Given:
[tex]\sum[/tex](1/4)(9/10)^n = 2.25
For S3, put n= 1 to 3
9/40 + 81/400 + 729/4000
= 900+810+7290/4000
=2439/4000
=0.60975
So, Truncation error= 2.25- 0.60975= 1.64025

Which of the following notations correctly describe the end behavior of the polynomial graphed below?
Answer:
Step-by-step explanation:
B. As x approaches negative infinity, f(x) appoaches positive infinity.
As x approaches positive infinity, f(x) approaches negative infinity.
For the given polynomial the end behaviour are -∞ and ∞. The correct option is (B).
How to find the end behaviour for a polynomial?A polynomial is defined as the algebraic expression having all the powers to its terms as whole number. In order to find the end behaviour of a polynomial p(x), determine its value for two cases when x approaches to infinity and minus infinity.
From the graph of the polynomial given in the problem it can be observed as,
As the value of x approaches ∞ , f(x) becomes -∞.
And, as the value of x approaches -∞ , f(x) becomes ∞.
Hence, the end behaviour are given as -∞ and ∞.
