the correct answer is b and a
Answer:
1 1/6 hours
Step-by-step explanation:
1 3/4 hours = 105 min
2/3 of 105 min = 70 min = 1 1/6 hours
-5x^2+4 = g(x) pretty simple
Answer:
a) 20 units
b) 2 √10 units
c) 2 √17 units
Step-by-step explanation:
The distance formula is;
D = √(y2-y1)^2 + (x2-x1)^2
a) D = √(-7-9)^2 + (-7-5)^2
D = √256 + 144
D = √400
D = 20
b) D = √(10-8)^2 + (9-2)^2
D = √(2)^2 + 6^2
D = √4 + 36)
D = √40
D = 2 √10 units
c) D = √(1 + 7)^2 + (-8+10)^2
D = √(64 + 4)
D = √68
D = 2 √17 units
<span>This is true. Because we don’t have more precision our of 6.3, we cannot append more digits with any certainty. We must omit the digit in the hundredths place in order to have a solutionwith correct precision using significant figures.</span>
