Answer:
D
Step-by-step explanation:
f(x) < 25
x² - 11 < 25
x² < 36
-6 < x < 6
A = pi * r^2
<span>A = 3.14 * 50^2 </span>
<span>A = 7,850 square miles (area of the 50 mile broadcast signal)
A = pi * r^2
A = 3.14 * 75^2
A = </span>17,662.5 = 17,663 square miles (area of the 75 mile relayed signal)
Now we just need to subtract the 50 mile signal from the 75 mile signal, so:
17,663 - 7,850 = <span>9,813 square miles greater
Hope this helps :)

1/2.54 = 90/x
Cross multiply
(1)x = (2.54)(90)
x would equal 228.6
The answer would be 90 in/ 228.6 cm.
well, we know is 10% for the first 7500, but Dan only made 5000 of taxable income, so he's in that range of 0 - 7500, so he only gets to pay 10% of 5000.

Sum= positive 30 because you add the opposite
The difference between the numbers is also 30
