Which sequence are geometric? select three options.

Options 1, 2 and 4 are the correct answers.

Option A, B and D are Geometric sequence. 

Step-by-step explanation:

Given the sequence we have to choose the option which is an geometric sequence.

In G.P, the common ratio i.e r remains the same

Option A: -2.7, -9, -30, -100,...

which is same hence G.P

Option B: -1, 2.5, -6.25, 15.625,..

which is same hence G.P

Option C: 9.1, 9.2, 9.3, 9.4,...

which is not same hence not a G.P

Option D: 0.8, 0.08, 0.008, ..

which is same hence G.P

Option E: 4, -4, -12, -20,..

which is not same hence not a G.P

pi x^2

step-by-step explanation:

pi times x squared

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
