He spent 26.95 on each. It's just 80.85/3 =26.95
25/100 is equal to 25%.
Percents are always out of 100.
So 25/100 is 25%.
Hope this helped☺☺
You look for certain key words. The expression "at least" means "greater than or equal to." The expression " is no more than" means "less than or equal to." A sum means an addition. A difference is a subtraction. There are many other words that you need to look out for and translate into math symbols.
Answer:
Step-by-step explanation:
It's an arithmetic sequence.
9 = 11 - 2
7 = 9 - 2
5 = 7 - 2
3 = 5 - 2
A) next three terms: 3 - 2 = 1, 1 - 2 = -1, -1 - 2 = -3
B) Common difference = -2
C) Recursive Function:
D) Explicit Function:
a₁ - first term
d - common difference
Substitute a₁ = 11 and d = -2:
Answer:

Step-by-step explanation:
Using the trigonometric identities
1 + tan²A = sec²A , secA = , cosecA = , cotA = , tanA =
Consider the left side
=
=
=
= × sin²A
=
= tanA = right side , thus proven
