Answer:
the equivalent expression is 1.1(1.3)^4 ×(1.3)^x
Answer:
The answer would be -16a⁴+8a³-1
The -4a² and 4a² cancel each other out so you put 1 in its place
I would range it from 2 to 30.
This is because the lowest value is 2 and the highest value is 30.
Hope this helps!
To find the volume of the model of the Earth, you will use the formula (rule) for finding the volume of a sphere.
You will divide the diameter by 2 to get the radius. 6.5/2 = 3.25 m
V = 4/3 x pi x r^3
= 4/3 x 3.14 x 3
V = 143.72 cubic meters
The volume of the model is approximately 143.72 cubic meters.
