Answer:
1) There exists a real number x such that for all real numbers y, xy ≤ y.
Step-by-step explanation:
Given the statement:
"There exists a real number x such that for all real numbers y, xy > y"
The negation of the statement is:
"There exists a real number x such that for all real numbers y, xy ≤ y"
The correct option is 1
Answer:
-125
Step-by-step explanation:
Each term is 7 less than the previous term.
1st term: 15
2nd term: 15 - 7
3rd term: 15 - 7 - 7 = 15 - 2(7)
4th term = 15 - 7 - 7 - 7 = 15 - 3(7)
Notice that each term is 15 minus a multiple of 7. The multiple is obtained by multiplying 7 by 1 less than the term number.
The formula is:
For the 21st term, multiply 7 by 20, and subtract from 15.
7 × 20 = 140
15 - 140 = -125
Using the formula:
Answer: -125
Answer:
Length A: 5 ft
Width B: 4 ft
volume = 88 ft³
Step-by-step explanation:
Length A: 8 - 3 = 5 ft
Width B: 8 - 4 = 4 ft
<u>Volume</u>
The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).
Volume of a rectangular prism = width x length x height
Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³
Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³
Total volume = 64 + 24 = 88 ft³
289 square root = 17
17*17=289
Say 17 was length and 17 was width. L*w=289
Also, all sides of the square are the same.
