A geometric sequence with a fifth term of 1/3 and a constant ratio of 1/3

1 answer:

7 0

We know that a 5 = 1/3 and r = 1/3
a 5 = a 1 * r^4
1/3 = a 1 * 1/3^4
1/3 = a 1 * 1/81
a 1= 1/3 : 1/81 = 1/3 * 81 = 27
Answer:
Geometric sequence is: 27, 9, 3, 1, 1/3, 1/9, 1/27,...

I saw this problem and the instruction was to graph the function and show the domain and range.

The domain is all the x-values while the range is all the y-values.

A parcel has a mass of 500g. Calculate its weight. (Assume the gravitational field strength is 10N/kg).

Elan Coil [88]

Answer:

The weight of the parcel is 5 N

Step-by-step explanation:

we know that

Weight can be calculated using the equation:

$W=mg$

where

W ----> weight (W) is measured in newtons (N)

m ----> mass (m) is measured in kilograms (kg)

g ----> gravitational field strength (g) is measured in newtons per kilogram (N/kg)

In this problem we have

$g=10\ N/kg$

$m=500\ g$

Remember that

$1\ kg=1,000\ g$

To convert g to kg

Divide by 1,000

$m=500\ g=500/1,000=0.5\ kg$

substitute the values in the equation

$W=(0.5)(10)=5\ N$

therefore

The weight of the parcel is 5 N

What is the approximate volume of a cone with a height of 12 in. and radius of 9 in.?

swat32

The answer would be 1017.88 in³. Use the volume for cones ( 1/3 times pi times radius times height) so 1/3*3.14*9*12 in which would be 1017.88 in³ hope it helps!
