\displaystyle\lim_{n\to\infty}\sqrt[n]{\left|\left(\frac{5n+15}{2n-1}\right)^n\right|}=\lim_{n\to\infty}\frac{5n+15}{2n-1}=\dfrac52

Since this limit exceeds 1, the series diverges.

The shardze family is planning A car trip to Atlanta Georgia which is 279 miles from their home they plan to drive at an average
Gnoma [55]
They are going 279 miles at a rate of 62 mph.

time = distance / speed
time = 279/62
time = 4.5 hrs...or (4 hrs 30 minutes)

plus they plan on a 45 minute lunch...
4 hrs and 30 minutes + 45 minutes = 4 hrs and 75 minutes = 
5 hrs 15 minutes. So they need 5 hrs and 15 minutes to get there...and they want to be there by 3.

So they will have to leave at : 9:45 <==

What is the solution to the system of equations?
Over [174]

ANSWER

C) (6,-8)

EXPLANATION

The equations are:

y =  \frac{1}{3}x - 10

and

2x+y=4

We substitute the first equation into the second equation to get:

2x +  \frac{1}{3}x - 10 = 4

We multiply through by 3 to get:

6x + x  - 30= 12

Group similar terms,

6x + x = 30 + 12

7x = 42

Divide both sides by 7 to get,

x =  \frac{42}{7}  = 6

Put this value of x into the first equation to get;

y =  \frac{1}{3} (6) - 10

y = 2 - 10 =  - 8

josie cast a shadow of 6ft and she is 5 ft 6 in tall. A building cast a shadow of 18 ft at the same time that josie measured her
Debora [2.8K]
Josie's height = 5 ft 6 in. = 5 1/2 ft = 11/2 ft.
Josie's shadow = 6 ft.

Ratio of shadow to height = 6 / 11/2 = 12/11
So, It would be equal to ratio of building's shadow to building's height.

18/x = 12/11
x = 18*11 /12
x = 3*11 / 2
x = 16.5

In short, Your Answer would be 16.5 Feet

Hope this helps!
