fatima wants to find the value of sin theta, given cot theta equals 4/7. which identity would be best for fatima to use?

Answers

we know that
1+cot ²∅=csc² ∅
cot ∅=4/7
so
1+(4/7)²=csc² ∅
csc² ∅=1+(16/49)
csc² ∅=(65/49)
csc ∅=(√65)/7

remember that
csc ∅=1/sin ∅
sin ∅=1/csc ∅------> sin ∅=7/√65-----> sin ∅=(7√65)/65

the answer is
the best identity to find sin ∅ is
1+cot ²∅=csc² ∅

if the sum of a number and two is doubled, the result is six less than three times the number. find the number. help me solve this, not great at math especially word problems thank you.

Answers

Let's call your number N.
The sum of a number and two is doubled: 2(N+2)
Six less than 3 times the number : 3N-6
The result is : =
Let's put it all together.

The answer is d)10.
Check your answer.
The sum of a number and two is doubled: 2(10+2)=24
Six less than 3 times the number : 3(10)-6=24
Good answer.

Final answer:

To solve the problem, create the equation 2(x + 2) = 3x - 6. Simplify the equation and solve for x to find the number.

Explanation:

To solve this problem, we can create an equation based on the given information. Let's call the number we're trying to find 'x'. The sum of the number and two can be written as (x + 2). Doubling this expression gives us 2(x + 2). 'Six less than three times the number' can be written as 3x - 6. So, we have the equation 2(x + 2) = 3x - 6. Solving this equation will give us the value of the number 'x'.

Expanding the equation, we get 2x + 4 = 3x - 6. Simplifying it further, we can subtract 2x from both sides to get 4 = x - 6. Adding 6 to both sides gives us 10 = x. Therefore, the number we're looking for is 10.
