A diver jumps into the ocean from a boat. She starts at an elevation of 0 feet, and her elevation decreases by 60 feet every min

kumpel [21]

Answer:

- 300 feet or 300 feet below sea level

Step-by-step explanation:

Starting elevation of diver = 0 feet

decrease of elevation in 1 minute = 60 feet

decrease of elevation in 1* 5 minute = 60*5 feet = 300 feet

therefore

in five minutes diver loses 300 feet elevation

Elevation of diver after 5 minute = Starting elevation of diver - value of decrease of elevation of diver in five minutes

Elevation of diver after 5 minute = 0 feet - 300 feet = - 300 feet.

Therefore Elevation of diver after 5 minute is - 300 feet

i.e 300 feet below sea level as sea level elevation is taken as standard value of elevation of 0 feet.

In a certain sequence of all positive terms, {a1, a2, a3, …} each term equals the previous term times a constant factor. If (a1)

andriy [413]

Let $k$ be the constant factor between terms, so that

$a_2=ka_1$

$a_3=ka_2=k^2a_1$

and so on, with

$a_n=ka_{n-1}=\cdots=k^{n-1}a_1$

(notice how the exponent and the subscript add to $n$ )

Then

$a_5=k^4a_1$

so if

$a_1a_5=900$

then

$k^4{a_1}^2=900\implies k^4=\dfrac{900}{{a_1}^2}=\left(\dfrac{30}{a_1}\right)^2\implies k^2=\dfrac{30}{a_1}$

Now,

$a_3=k^2a_1=\dfrac{30a_1}{a_1}=30$

so the third term in the sequence is 30.

What role does Geometric formulas have in our lives??

amid [387]

Geometry helps us in deciding what materials to use, what design to make and also plays a vital role in the construction process itself. Different houses and buildings are built in different geometric shapes to give a new look as well as to provide proper ventilation inside the house.

Hope that helped :)
