Cos t (sec t - cos t)
= cos t (1 / cos t - cos t)
= 1 - cos^2 t
= sin^2 t (using the identity sin^2 t + cos^2 t = 1 )
Answer:
3240
Step-by-step explanation:
If the simple interest is 8%, Mr. Kim will have to pay $3000, and the simple interest, which will be 8% of $3000.
You can write it in two ways:
3000+3000*0.08= 3240
or
3000*1.08= 3240
I hope this helps you
6 (x^2+3x)=0
x (x+3)=0
x=0
x+3=0
x= -3
If it’s a factor then it’s 2 but if your doing a expression then it is just 2x+2
For this case we have the following variable:
m = Santana's total marbles
We must write an expression as a function of m to model the problem.
"Santana wants to give one-thenths of all his marbles plus eight to his brother"
The function is:
f (m) = (1/10) m + 8
Answer:
An expression that Santana can use is:
f (m) = (1/10) m + 8
