Answer:
-3
Step-by-step explanation:
The variable is x.
It's multiplied by -3
● -3 × x = -3x
An=a*q^(n-1)
a7=a*q^6
a7=4096*(1/2)^6=4096/32=128

Answer:
7 7/8
Step-by-step explanation:
There are several ways to get there.
2.25×3.5 = 7.875 = 7 7/8
(2 1/4)(3 1/2) = (9/4)(7/2) = 63/8 = 7 7/8
(2 1/4)(3.5) = 2(3.5) +(1/4)(3.5) = 7 + (2·3.5)/(2·4) = 7 +7/8 = 7 7/8
A typical graphing calculator will let you enter this problem directly, giving you a result either as a decimal, improper fraction, or a mixed number.
Answer:
10 units
Step-by-step explanation:
the longest length is from (11, 1) to (3, 7) and can be clearly shown when graphed
now to find the length you must use the pythagorean theorem
the distance between 11 and 3 is 8 and the distance between 1 and 7 is 6 so
8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
c = 10
that is your answer
Csc x · sec x - tan x =
= 1 / sin x · 1 / cos x - sin x / cos x =
= 1 / sinx cos x - sin² x / sin x cos x =
= ( 1 - sin² x ) / (sin x cos x) =
= cos² x / ( sin x cos x ) =
= cos x / sin x = cot x
