Answer:
Larry would be wrong if 2(as a prime number) is part of the numbers that has 2 at its ones place, but if 2 is not there, then he is correct.
Step-by-step explanation:
Firstly, we need to know what a composite number is. In simple terms, a composite number is a number that is not a prime number. Meaning that, if a number has more than two factors (1 and itself which is the definition for a prime number), then the number is a composite number.
Larry says all numbers that have 2 in their ones place are composite. It depends, if 2 is the only number that makes up the digit, that is the number itself is 2, then it's obviously a prime number. But any other number having 2 at its ones place is definitely a composite number because the number has more than 2 factors; 1, itself and 2. Example:
12, some of the factors is 1, 12 and 2. Therefore it is a composite number.
Larry would be wrong if 2(as a prime number) is part of the numbers that has 2 at its ones place, but if 2 is not there, then he is correct.
Interesting problem ...
The key is to realize that the wires have some distance to the ground, that does not change.
The pole does change. But the vertical height of the pole plus the distance from the pole to the wires is the distance ground to the wires all the time. In other words, for any angle one has:
D = L * sin(alpha) + d, where D is the distance wires-ground, L is the length of the pole, alpha is the angle, and 'd' is the distance from the top of the (inclined) pole to the wires:
L*sin(40) + 8 = L*sin(60) + 2, so one can get the length of the pole:
L = (8-2)/(sin(60) - sin(40)) = 6/0.2232 = 26.88 ft (be careful to have the calculator in degrees not rad)
So the pole is 26.88 ft long!
If the wires are higher than 26.88 ft, no problem. if they are below, the concerns are justified and it won't pass!
Your statement does not mention the distance between the wires and the ground. Do you have it?

Answer:
C
Step-by-step explanation:
Literally just do the work yourself man...
R = (2s - 6t + 5)/2
2R = 2s - 6t + 5
2s = 2R + 6t - 5
s = (2R + 6t - 5)/2
