(05.08 MC) What is the equation for a geometric sequence with a first term of 4 and a second term of −8? (5 points)

an = 4(2)n − 1
an = 4(−2)n − 1
an = 4(−12)n − 1
an = 4(12)n − 1

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

step-by-step explanation:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
