Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
another way to name 1/4 is a quarter because 1/4 of 100 is 25 %, so that's why it is called a quarter.
hopefully this helps you :)
Answer:
All make numbers make that statement true
Step-by-step explanation:
6406358 + 8550780= 14957138
14957138-5598256= 9358882
therefore is you add any number to 5598256 that is greater than 9358882 then the statement will be true. All those numbers given are larger than 9358882
follow these steps:
1) y-4=7x^2
2) (y-4)/7 = x^2

so you must inverse x and y names:

Answer:
Answer is J
Step-by-step explanation:
Find one point: (1,0)
Substitute the numbers in the equations.
0+6= 3(1+1)
6= 3(2)
6=6
