Piper is driving on a long road trip. She currently has 11 gallons of gas in her car. Each hour that she drives, her car uses up

Fynjy0 [20]

Answer:

begins the trip with 14 gallons of gas in her car.

The car uses up one gallon of gas every 30 miles.

Let g represent the number of gallons of gas she has left in her tank, and let d

represent the total distance

Step-by-step explanation:d = 30(14 - g)

For example, if she uses two gallons, there will be 12 gal left in the tank; g=12

d = 30(14 - 12)

d = 30(2)

d = 60 mi Here you go

Convert to pounds

4.2 kg=4.2*(2.2)=9.24 pounds

therefore

the answer is 9.24 pounds

Suppose an=3an-1 -5an-2 -4an-3. and a4= -7, a5=-36, a6=-85 , find a1 , a2, a3

maria [59]

Answer:

$a_1=4\\\\a_2=0\\\\a_3=3$

Explanation:

The equation is:

$a_n=3a_{n-1}-5a_{n-2}-4a_{n-3}$

and

$a_4=-7, a_5=-36, a_6=-85$

1. Subsittute n = 6 into the equation:

$a_6=3a_{5}-5a_{4}-4a_{3}$

Now subsititute the known values:

$-85=3(-36)-5(-7)-4a_{3}$

You can solve for $a_3$

$-85=-108+35-4a_{3}\\\\4a_3=12\\\\a_3=12/4\\\\a_3=3$

2. Substitute n = 5 into the equation:

$a_5=3a_{4}-5a_{3}-4a_{2}$

Substitute the known values and solve for $a_2$

$-36=3(-7)-5(3)-4a_{2}\\\\4a_2=-21-15+36=0\\\\a_2=0$

3. Substitute n = 4 into the equation, subsitute the known values and solve for $a_1$

$a_4=3a_{3}-5a_{2}-4a_{1}$

$-7=3(3)-5(0)-4a_{1}\\\\4a_1=9+7=16\\\\a_1=4$

The measure of angle O is 7pi/6. The measure of its reference angle is.... ° and sin O is .....

scoray [572]

$\frac{7 \pi }{6}$ is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)
$\frac{7 \pi }{6} - \pi = \frac{ \pi }{6}$ (or 30 degrees)

sin $\frac{ \pi }{6} = \frac{1}{2}$
