test grades: 75, 82, 88, 70

Average = Total sum of all numbers/number of item in the set

Total sum of all numbers = 75 + 82+ 88 + 70 = 315

number of item in the set = 4

Average = 315/4 = 78.75

Is 8/10 mile longer than 1/2
seropon [69]
Yes because if you find common denominators (in this case, "10") you would have to compare 8/10 to 5/10. 8>5 so 8/10 is longer than 1/2.

Given the geometric sequence where a1=1 and the common ratio is 6, what is the domain for n?​
kari74 [83]

We have been given that a geometric sequence's 1st term is equal to 1 and the common ratio is 6. We are asked to find the domain for n.

We know that a geometric sequence is in form a_n=a_1(r)^{n-1}, where,

a_n = nth term of sequence,

a_1 = 1st term of sequence,

r = Common ratio,

n = Number of terms in a sequence.

Upon substituting our given values in geometric sequence formula, we will get:

a_n=1\cdot (7)^{n-1}

Our sequence is defined for all integers such that n is greater than or equal to 1.

Therefore, domain for n is all integers, where n\geq 1.

Multiply (-8x - 9)(-9x2 + 7x - 9).
Misha Larkins [42]
= <span>(-8x - 9)(-9x2 + 7x - 9)

= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81

= 72x³ + 25x² + 9x + 81

In short, Your Answer would be: Option D

Hope this helps!
