Answer:
176 meters
Step-by-step explanation:
Stefano is at +10 elevation, the hiker is at -166.4
10 + 166.4 = 176.4 ≈ 176 meters
3² + 7 - y² - 5 - 2y² -1
= -3y² + 9 + 1 = -3y² + 10
Answer + Step-by-step explanation:
<u>the conditional statement</u> :
For two positive integers n and m,
nm = 4 ⇒ (n = 1 or m = 1) or (n=m= 2)
<u>the contrapositive</u>:
(n ≠ 1 and m ≠ 1) and (n ≠ 2 or m ≠ 2) ⇒ nm ≠ 4
<u>Prove the conditional by proving the contrapositive</u> :
Suppose
m ≠ 1
and m ≠ 2
and n ≠ 1
⇒ nm ≠ 1 × n and nm ≠ 2 × n and n ≠ 1
⇒ nm ≠ 4 (because 4 = 4 × 1 or 4 = 2 × 2)
<u>Conclusion</u>:
The contrapositive is true then conditional is true.
Answer:
Step-by-step explanation:
Given that demand function for a product is modeled by
where p = price in dollars and
x= units demanded
a) When x=1000, we substitute 1000 for x
i.e. price is 1092.32 dollars
b) X = 1500
i.e. price is 692.28 dollars
c) When x increases without bound exponent with negative power becomes 0 making price = 10000(1-3/3) =0
Answer:
number of sides = sum of angles÷each angle
therefore no. of sides=360÷12=30
