Answer:
The answer is option 2.
Step-by-step explanation:
First, you have to make the equation into 0, by adding 6x² to both sides :
Next, you have to apply Discriminant formula, D = b² - 4ac. Given that a quadratic equation is ax² + bx + c = 0, so for this equation a represents 6, b is -4 and c is 3 :
Answer:
27 Meters
Step-by-step explanation:
Surface Area = 2×(3×2 + 3×1.5 + 2×1.5)
W(-4,7); X(-2,1); Y(2,1); Z(4,4)
1 mg = 0.001 grams. therefore 2000 mg = 2 grams
Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.
