Answer:
To my understanding, it's not a number.
Instead, it's a rank.
Try to answer questions until you rank up. Then you can chat.
Answer:
there are two complex roots
Step-by-step explanation:
Recall that for a quadratic equation
y = ax² + bx + c
the solution given by the quadratic formula is
x = ( -b ± √discriminant) / 2a
if the discriminant is negative, the radical term will become √ (negative number), which we know gives complex solutions. Hence we can eliminate real roots as possible answers.
Also notice that the "±" sign in the quadratic formula means that you will get 2 possible solutions:
x = ( -b + √discriminant) / 2a
or
x = ( -b - √discriminant) / 2a
Hence we know we will get 2 solutions.
Combining our findings, we can conclude that if the discriminant is negative, we will get 2 complex roots.
42 gallons weigh 7(42) or 294 pounds
<span>each cubic foot weighs 52 pounds </span>
<span>so the number of cubic feet = 294/52 = 5.654 ft^3</span>
If 7 out of 10 candles are lit, then seven-tenths of the candles are lit. The tenths place is directly to the right of the decimal. Since you have seven-tenths, the tenths place will be seven. So, the decimal that represents the candles lit will be 0.7
