<span>The island that has the population density ranging from less than to up to two hundred fifty people per square mile is Vancouver Island. The island is roughly 12,079 square miles with a total population of 748,937 according to the 2009 census bureau.</span>
(f + g)(x) means f(x) + g(x)
So, you just input the function of f(x) and g(x) altogether, then simplify it.
(f + g)(x)
= f(x) + g(x)
= 2x² + 1 + x² - 7
= 2x² + x² + 1 - 7
= 3x² - 6
The answer is b
Answer:
Step-by-step explanation:
<u>Arc length formula:</u>
<u>Substitute values:</u>
- s = 2*3.14*15(80/360) = 20.93 in
Argument
The only number he can't roll is the number one. There are 5 numbers that he can roll.
The probability of success therefore is 5/6.
Formula
Number of successful rolls = probability of success * total number of rolls.
Total number of rolls = 78
Probability = 5/6
Number of successful Rolls = 5/6 * 78
Number of successful Rolls = 390/6
Number of successful Rolls = 65
Answer
He should roll a number greater than one 65 times <<<<< answer
To solve this you will need to know the Pythagorean therum A^2+B^2=C^2
24^+B^2=28^2
576+B^2=784
-576. -576
B^2=208
Square root of 208 is about 14.42 and that is the length of the wall
