Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:
In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:
Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
Answer:41a
Step-by-step explanation: when you multiply a number and a variable it will give you the number and the variable which is the unknown
Answer:
84 sq.m.
Step-by-step explanation:
Given : Sides of triangle are 13 cm,14 cm and 15 CM
To Find :find the area of the triangle
Solution:
We will use heron's formula :
Where
a = 13
b = 14
c = 15
Hence the area of the triangle is 84 sq.m.
Tip: use Heron's formula
Answer:
1/4w -1
Step-by-step explanation:
(1/2w +3) -(1/4w +4) = w(1/2 -1/4) +(3 -4)
= 1/4w -1
