Answer:
6/21, 12/42
Step-by-step explanation:
Mary spends no more than 21 hours a week doing homework. If she spends 2/7 of the time doing her math homework.
The number of hours she spends doing her maths homework is calculated as:
= 2/7 × 21
= 6 hours
The other fractions that could represent the amount of time Mary spends doing her math homework is given as:
6 hours/21 hours = 6/21
Also , that could be represented as:
12/42
Therefore, the other fractions that could represent the amount of time Mary spends doing her math homework is : 6/21 , 12/42
<span>It is symmetric to X,Y-Axis</span>
Cos (π/2 - x) = sin x = 3/5
tan x = sin x / cos x = 3/5 / 4/5 = 3/4
csc x = 1/sin x = 1 / 3/5 = 5/3
sec x = 1/cos x = 1 / 4/5 = 5/4
cot x = 1/tan x = 1 / 3/4 = 4/3.

Answer:
(3+d)(9-3d+d^2)
Step-by-step explanation:
a^3 + b^3 = (a+b)(a^2-ab+b^2)
a= 3
b= d
