A motorboat travels 275 kilometers in 5 hours going upstream. It travels 405 kilometers going downstream in the same amount of t

VladimirAG [237]

Step-by-step explanation:

$275 \times 5 = 1375$

The rate of the motorboat on still water is 1375

$405 \times 5 = 2025$

The current rate of the motorboat is 2025

Please help me with this question.

Answer:

Step-by-step explanation:

In a triangle, the sum of any two sides must be bigger than the third.

For the first one, 10+20=30 is not greater than 30, so this is not correct.

For B, 122+137 = 259 > 257, 257+137>122 , and 257 + 122 > 137. This works

For C, 8.6 + 2.7 = 11.3 < 12.2, so this does not work

For D, 1/6 + 1/5 = 5/(6*5) + 6/(6*5) = 5/30 + 6/30 = 11/30 < 1/2 = 15/30, so this does not work

If f(x) = 2x2 + 1 and g(x) = x2 - 7, find (f + g)(x).

pishuonlain [190]

Answer:

(f+g)(x) = $3x^{2} - 6$

Step-by-step explanation:

First, lets understand what (f+g)(x) means.

(f+g)(x) is when you are taking the values in the function f(x) and adding it to the values in the function g(x).

So, this is what the equation looks like when you substitute the functions in to (f+g)(x):

(f+g)(x) = $(2x^{2} +1) + (x^{2} -7)$

Now, combine like terms and Simplify:

(f+g)(x) = $3x^{2} - 6$

This is your final answer.
