Which exponential function models a geometric sequence with initial value a and a common ratio of 0.7? 1 O f(n) = a(0.7) f(n) = a(0.7)" 1 O f(n= a + (0.7)" O f(n) = a + (0.7)" 1 1

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
