A 50-gallon rain barrel is filled to capacity. It drains at a rate of 10 gallons per minute. Write an equation to show how much

makvit [3.9K]

Answer:

The quantity of water drain after x min is 50 $(0.9)^{x}$

Step-by-step explanation:

Given as :

Total capacity of rain barrel = 50 gallon

The rate of drain = 10 gallon per minutes

Let The quantity of water drain after x min = y

Now, according to question

The quantity of water drain after x min = Initial quantity of water × $(1-\dfrac{\textrm rate}{100})^{\textrm time}$

I.e The quantity of water drain after x min = 50 gallon × $(1-\dfrac{\textrm 10}{100})^{\textrm x}$

or, The quantity of water drain after x min = 50 gallon × $(0.9)^{x}$

Hence the quantity of water drain after x min is 50 $(0.9)^{x}$ Answer

Elmer sees a flying saucer. The radius of the flying saucer is 17 feet. What is the area of the flying saucer (use 3.14 for pi a

sergiy2304 [10]

Answer:

Area of the flying saucer = $907.46 ft^2$

Step-by-step explanation:

The Flying saucer is in the shape of a circle.

$Radius= 17 feet$

Area of the circular flying saucer= $\pi *r*r$

: $\pi =\frac{22}{7} =3.14$

Area= $3.14*17*17$

Area of the flying saucer $=3.14*289\\\\ =907.46 ft^2$

So, the area of the flying saucer is $907.46 ft^2$

raketka [301]

The first space is for the slope, which would be 2. The second is for the y-intercept, which is 110.

So if you fill those in, it would be N=2M+110

A sequence is defined by the recursive function f(n + 1) = 1/3f(n). If f(3) = 9 , what is f(1)

lord [1]

Answer:

f(1) = 81

Step-by-step explanation:

given is f(n + 1) = 1/3f(n)

f(3) = 9

ayou need to find f(0) before you can answer what is f(1).

Just start by applying for...

n=0

f(0+1) = 1/3 * f(0)

f(1) = 1/3 * f(0)

n=1

f(1+1) = 1/3 * 1/3*f(0)

f(2) = 1/9 * f(0)

n=2

f(2+1) = 1/3 * 1/9* f(0)

f(3) = 1/27 * f(0)

But it is given that f(3) = 9 so substitute this in the line above to calculate the value of f(0)....

9 = 1/27 * f(0)

Multiply left and right of the = sing by 27 gives

f(0) = 27 * 9

f(0) = 243

We already know this next line because we started with n=0

f(1) = 1/3 * f(0)

Substitute f(0) = 243 in the line above to finally calculate the value of f(1).

f(1) = 1/3 * 243

f(1) = 81
