Answer:16.5
Step-by-step explanation:
Hi there! Use the following identities below to help with your problem.
What we know is our tangent value. We are going to use the tan²θ+1 = sec²θ to find the value of cosθ. Substitute tanθ = 4 in the second identity.
As we know, sec²θ = 1/cos²θ.
And thus,
Since the given domain is 180° < θ < 360°. Thus, the cosθ < 0.
Then use the Identity of sinθ = tanθcosθ to find the sinθ.
Answer
- sinθ = -4sqrt(17)/17 or A choice.
Answer:
b = -8
Step-by-step explanation:
6b = -42
Divide by 6 on both sides
b = -8
Answer:
44 cups = 27.5 gallons
Step-by-step explanation:
Using the conversion:
We can find what is 44 cups in gallons.
=> 1 cup = 0.625 gallons
=> 44 x 1 = 0.625 x 44
=> 44 cups = 0.625 x 44 gallons
=> 44 cups = 27.5 gallons
Therefore, 44 cups = 27.5 gallons.
Hoped this helped.
The statement that best describes the two expressions is
D. A is irrational, but B is rational
square root of 64 plus square root of 5 is 8 plus square root of 5, the square root of 5 is an irrational number which makes the entire expression an irrational number
square root of 64 plus square root of 4 is 8 plus 2 which is equal to 10 and is a rational number
