Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.
Examples:
1 and 2
Sum of squares = 5
√5 is irrational
2 and 3
Sum of squares = 13
√13 is irrational
4 and 5
Sum of squares is 41
√41 is irrational
'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .
a 'Pythagorean triple'.
Examples:
3 and 4
Sum of squares is 25
√25 = 5 is rational yay
5 and 12
Sum of squares is 169
√169 = 13 is rational yay
Answer:
f(x)=1 (B)
Step-by-step explanation:
f(x) = 2X-7
f(4) = 2(4)-7
=8-7
=1
Answer:
-8b-8 hope this helps (:
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
A cubic with a positive leading coefficient will have a general trend of upward to the right. (If the leading coefficient is negative, it will trend downward.) If there is only one real zero, it will cross the x-axis exactly once. There may or may not be two turning points, but there won't be any more than that. (There may be no turning points.)
The attached graph shows a couple of examples. The turning points and inflection points may be on either side of the x-axis.
The total number of yards is 360 yards
<h3>How to determine the number of yards?</h3>
The given parameters are:
Number of sheets = 8
Yard per sheet = 45 yards
The total number of yards is calculated as:
Total number of yards = Number of sheets * Yard per sheet
Substitute the known values in the above equation
Total number of yards = 8 * 45 yards
Evaluate the product
Total number of yards = 360 yards
Hence, the total number of yards is 360 yards
