Answer:
b=√119
Step-by-step explanation:
a2+b2=c2
(5×5)+(b2) =(12×12)
25+b2=144
b2=144-25
b2= 119
b=√119
Front end estimation for this question would be to the nearest hundred. So 125 rounded to the nearest hundred is 100, 123 to the nearest hundred is 100, 392 to the nearest hundred is 400, and 294 to the nearest hundred is 300. Adding 100 + 100 + 400 + 300 would be 900.

You can infer from this problem that for every 100 m that
John was able to run, it takes him 9.93 seconds. To get how much time is needed
for 26 – mile marathon, you need to divide 26 miles by 100 meters. But first,
you need to convert 26 miles to meters first.
1 mile = 1,609.34 meters
26 miles = 41,842.84 meters
41,824.84 meters / 100 meters = 418.43 x 9.93 seconds =
4,155 seconds or 69.25 minutes
Answer:
B
Step-by-step explanation:
The "value" of a function is the y-value.
Since we want negative y values, we look at "WHERE" the function is "UNDER" the y-axis.
Looking closely, it looks that function (the dip) is from x = -1 to x = 3
Hence, the function is negative at the interval -1 ≤ x ≤ 3
B is correct.
