What quadratic formula do I need to use to solve 3x(x+6)=-1

timofeeve [1]

Answer:

$\Large \boxed{x_1=\frac{9+\sqrt{51} }{3} \ \ ; \ \ x_2=\frac{9-\sqrt{51} }{3} }$

Step-by-step explanation:

$\displaystyle \Large \boldsymbol{} 3x(x+6)=-10 \\\\3x^2+18x=-10 \\\\3x^2+18x+10=0 \\\\D=324-120=204 \\\\ x_{1;2}=\frac{18\pm2\sqrt{51} }{6} =\frac{9\pm\sqrt{51} }{3}$

During his hike, Milt drank 1 liter of water and 1 liter of sports drink. How many milliliters of liquid did he drink?

S_A_V [24]

Answer: 2,000 milliliters.

Step-by-step explanation:

Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:

1 liter + 1 liter = 2 liters of liquid.

Finally, we have to convert the result into milliliters.

Since 1 liter = 1000 liters

We have to multiply the liters drank by 1000.

2 x 1000 = 2,000 milliliters.

Feel free to ask for more if needed or if you did not understand something.

A tropical storm has been moving at 15 miles per hour for the past two days. Bess recorded that the storm moved 135 miles yester

Allushta [10]

Answer:

Bess has been keeping track of the storm for 14 hours.

Step-by-step explanation:

The tropical storm has been moving at 15 miles per hour.

Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

$135+75=210$

The relationship between distance speed and time is defined as

$speed=\frac{distance}{time}$

$15=\frac{210}{time}$

$time=\frac{210}{15}$

$time=14$

Therefore, Bess has been keeping track of the storm for 14 hours.

If x 2 = x + 1, find x 3 , giving your answer in the form ax + b.

GalinKa [24]

Answer:

${x}^{2} = x + 1 \\ x = {x}^{2} - 1 \\ {x}^{3} = { ({x}^{2} - 1)}^{3} \\ = (x - 1) {}^{3} (x + 1) {}^{3}$

How do you solve this?

mel-nik [20]

Answer:

Horizontal component = 9.6

Step-by-step explanation:

Recall that the horizontal component is given by the cosine projection;

$v_x=|v_0| * cos(\theta)$

which in our case (using the fact that in each degree of angle one has 60 minutes of angle, and therefore 30 minutes of angles is the same as 0.5 degrees) becomes:

$v_x=12.6 * cos(40.5^o)=9.5811$

And rounding to the nearest tenth as requested, we have:

$v_x=9.6$
