Answer:

121

Step-by-step explanation:

to find the average, you are going to add them together and divide by two, because you have two numbers. so 137 + 105 = 242. then divide. 242/2 = 121 that is your answer.

Hi,

The sum of ten and a number.

Usually AND refers to adding, that's just the rules of math according to writing equation. Times would be multiplying, taking away is subtraction and divided by is dividing.

So if the question uses AND, it's adding.

Answer:

Correct choice is B

Step-by-step explanation:

All three functions are increasing when x is increasing. You can find values of each function when x is "enough large". For example, at x=100,

1. linear function: $y=10\cdot 100=1,000.$

2. exponential function: $y=5^{100}\approx 0.8\cdot 10^{70}.$

3. quadratic function: $y=4\cdot 100^2+5\cdot 100=40,500.$

As you can see, when x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.

Also you can use graphical method to get from the attached diagrams result. When x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.

Correct choice is B.
