Answer:
180degrees
Step-by-step explanation:
Given the expression cos^2x - cos x - 2 = 0
Let P = cos x
P^2 - P - 2 = 0
Factorize
P^2 - 2P + P - 2 =0
P(P-2)+1(P-2) = 0
P-2 = 0 and P + 1 = 0
P = 2 and P = -1
Since P = cos x
cos x = -1
x = arccos(-1)
x = 180degrees
Hence the require angle is 180degrees
10, 8, 6, 4,…
-2 -2 -2
a(n) = a₁ + d(n - 1)
a(n) = 10 - 2(n - 1)
a(n) = 10 - 2(n) + 2(1)
a(n) = 10 - 2n + 2
a(n) = -2n + 10 + 2
a(n) = -2n + 12
The answer would be 11.56, it has 4 digits, it is greater then 11 but smaller than 12 the sum of the digits is 13 and 6 is in the hundredths place.
Answer:
$637.5
Step-by-step explanation:
Given data
Cost of merchandise= $750
Discount= 15%
Let us find the amount of the discount
=15/100*750
=0.15*750
=$112.5
Hence the amount paid will be
=750-112.5
=$637.5
