Answer:
-0.6309
Step-by-step explanation:
Using the change of base formula,
Log 1/2 to base 3 = Log1/2 ÷ Log 3 = Log 0.5 ÷ Log 3
Log 0.5 = -0.3010
Log3 = 0.4771
Log 0.5 ÷ Log 3 = -0.3010 ÷ 0.4771 = -0.6309
What numbers above? Please add more details.
Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
Applying the completing square method:
f(x) = 2x² - 8x + 6
Dividing by a
f(x) = 2(x² - 4x + 3)
Adding and subtracting the square of b (which is 2 in this case)
f(x) = 2(x² + 2² - 4x -2² + 3)
f(x) = 2(x - 2)² - 2
The vertex is (2, -2) and it is a minimum since the coefficient of x is positive.
The answer is B.
Answer:
880
Step-by-step explanation:
the train travels=220km in 4 hours
therefore, multiply 220 and 4
=220 x 4 = 880
so, the train travels 880 km in 9 hours
HAVE A GREAT DAY!
