Find cos theta if csc theta = square root 5

Answers

Answer:

cos theta = adjacent/hypotenuse = $(2)/(√(5) )$

Step-by-step explanation:

csc theta = hypotenuse/opposite = $√(5)$ /1 (reciprocal identity)

1^2 + b^2 = $√(5)$ ^2 (pythagorean theorem)

b^2 = 5-1

b = 2

cos theta = adjacent/hypotenuse = 2/ $√(5)$ (quotient identity)

so the qustion is which of these shos the commutative property
the commutative property of multiplication is
note:ab=a times b=a(b)

so a(bc)=(ab)c

first choice: 4.1 times (6.2 times 5.0)=(4.1 times 6.2) times 5.0
this is obviously the right answer A is the answer

B
2.7 times 1=2.7 this is the identity property of multiplicaiton, anything times 1= same thing

C 7.2 times 0=0 this is the 0 property of multiplication

D. 8.5 times 0.4=0.4 times 8.5
this is the equality property

the answer is A

How do you factor, 45c + 10d?

Answers

We can't factor out a c or d, since we don't know c in terms of d, or vise versa. We thus can only factor out an integer. We see that both numbers are divisible by 5, so we factor out a 5, for a result of 5(9c+2d). 9 and 2 do not have any common factors other than 1, so we have factored fully. Thus, the answer is 5(9c+2d).

Describe how to decide if 94 is a prime number or composite number

Answers

94 is a composite number.

If 94 were a prime number, 94 would only have 2 factors, which are 1 and itself. Since 94 has another factor other than 1 and itself (which is 2), 94 is a composite number.

Hope this helps~

to decide if 94 is a prime number or composite numberyou must find the prime factorization
