It is not periodic. A periodic dataset is a dataset that repeats the same pattern over time.
Answer: A.
Step-by-step explanation:
To answer this, you must first understand what fractional exponents mean.
An exponent of 1 is simply the base itself. 7^1 = 7.
An exponent of 2 is squaring the base: 7^2 = 49.
An exponent of 1/2 is taking the square root of the base: 7^(1/2) = sq root of 7
Therefore, an exponent of 1/3 is taking the cube root of the base.
In this case, the base is 2.03 * t.
Therefore, this can be represented as the cube root of the product of 2.03 and the age of the mammal, so the answer is A.
First term ,a=4 , common difference =4-7=-3, n =50
sum of first 50terms= (50/2)[2×4+(50-1)(-3)]
=25×[8+49]×-3
=25×57×-3
=25× -171
= -42925
derivation of the formula for the sum of n terms
Progression, S
S=a1+a2+a3+a4+...+an
S=a1+(a1+d)+(a1+2d)+(a1+3d)+...+[a1+(n−1)d] → Equation (1)
S=an+an−1+an−2+an−3+...+a1
S=an+(an−d)+(an−2d)+(an−3d)+...+[an−(n−1)d] → Equation (2)
Add Equations (1) and (2)
2S=(a1+an)+(a1+an)+(a1+an)+(a1+an)+...+(a1+an)
2S=n(a1+an)
S=n/2(a1+an)
Substitute an = a1 + (n - 1)d to the above equation, we have
S=n/2{a1+[a1+(n−1)d]}
S=n/2[2a1+(n−1)d]
