Answer:
1.38 to the nearest hundredth.
Step-by-step explanation:
Dividing:
x + 1 ) 3x - 1 ( 3
3x + 3
-4
so (3x - 1) / (x + 1) = 3 - 4 / x+ 1
Integral of (3 - 4 / x+1 ) = 3x - 4 ln(x + 1)
Between limits of 1 and 2 we have:
(3(2) - 4 ln 3) - (3 - 4 ln2)
= 1.6056 - 0.2274
= 1.3782.
7n^2 + 5 = 453
Subtract 5 from both sides:
7n^2 = 448
Divide both sides by 7:
N^2 = 64
Take the square root of both sides:
N = 8
Answer:
The maximum safe rescue height is 104.6 feet above the height of the ground.
Step-by-step explanation:
Consider a triangle ABC where C is the point where the rescue ladder is standing and AB be the building and Ladder making an angle of 72° as shown.
We have to find the height of the building.
Let x be the height of building
Using Trigonometric ratio,





So, the maximum safe rescue height is 104.6 feet above the height of
the ground.
Answer:
Jenna has run the distance of
miles .
Step-by-step explanation:
The Distance for the trail = 8
= 
Or , Distance =
miles
The distance cover by Jenna =
miles of the distance
I.e The distance cover by Jenna =
×
Or, The distance cover by Jenna =
miles
Hence Jenna has run the distance of
miles . Answer
The equation of the elipse is given by:

The equation of an elipse of center
is given by:

Values a and b are found according to the <u>vertices and the eccentricity</u>.
It has vertices at (1,0) and (27,0), thus:




It has eccentricity of
, thus:



Thus, b is given according to the following equation:





The equation of the elipse is:
