Area= pi x r^2
= pi x 13^2
=pi x 169
= 530.929
= to the nearest whole number 531
Answer:
Since,

Here, the given equation is,
|a| < b
Case 1 : if a ≥ 0,
|a| < b ⇒ a < b
Case 2 : If a < 0,
|a| < b ⇒ -a < b ⇒ a > - b
( Since, when we multiply both sides of inequality by negative number then the sign of inequality is reversed. )
|a| < b ⇒ a < b or a > - b ⇒ -b < a < b
Conversely,
If -b < a < b
⇒ a < b or a > - b
⇒ a < b or -a < b
⇒ |a| < b
Hence, proved..
Answer:
Step-by-step explanation:
Notice that f(x) = ab would be a constant function, as 'x' does not appear on the right side. If 'a' were increased by 2, the magnitude of f(x) would be increased by a factor of 2. The domain of f(x) would not change; the range would be [a·(b+2)) (a single numeric value).

Answer: 5¹⁵/₁₆
Step-by-step explanation:
The Wildflower Trail is currently 2³/₈ miles long.
If the city will extend it by 2¹/₂ in 5 years, the length in five years will be;
= 2³/₈ * 2¹/₂
= 19/8 * 5/2
= 95/16
= 5¹⁵/₁₆
