Answer:
Step-by-step explanation:
The values of the cosine function are represented by the axis OX of the goniometric circumference (circumference centered at the origin and of radius 1). Therefore the cosine is zero for the 90º and 270º angles.
Answer:
4
Step-by-step explanation:
Given that 


Now,


This can be written as
[as
]

[ by using equation (i)]
=4
Hence, 
So p - $15 = $49 and to solve it subtract 15 from 49 and then you will get your answer
The expression 2×2×2×5 shows the prime factorization of 40.
Prime factorization:
The number 40 is equal to
2 x 2 x 2 x 5, or = 40
23 x 5. = 40
<h3>
What does prime factorization serve as?</h3>
In mental arithmetic, fractions, finding square roots, and computing the HCF and LCM of two smaller numbers, prime factorization is a highly helpful tool when working with whole numbers. A whole number higher than 1 whose only elements are 1 and itself is referred to as a prime number. A whole number that may be split evenly into another number is referred to as a factor.
