Subtract 18d from both sides

subtract 9k from both sides

simplify 5k + 10 - 18d - 9k to -4k + 10 - 18d

factor out the common term 2

divide both sides by 2

cancel 2 and now simplify brackets

Answer: D) m < -2k + 5 - 9d or the fourth option.

If sin θ=.55 what is the value of cos θ and explain why

MatroZZZ [7]

Answer:

$cos(\theta)=(+/-)0.84$

Step-by-step explanation:

we know that

$sin^2(\theta)+cos^2(\theta)=1$ ----> by trigonometric identity

we have

$sin(\theta)=0.55$

substitute

$(0.55)^2+cos^2(\theta)=1$

$cos^2(\theta)=1-(0.55)^2$

$cos^2(\theta)=0.6975$

$cos(\theta)=(+/-)\sqrt{0.6975}$

$cos(\theta)=(+/-)0.84$

Remember that

If the sine of angle theta is positive, then the angle theta lie on the I Quadrant or II Quadrant

therefore

If the angle theta is on the I Quadrant the cosine will be positive

If the angle theta is on the II Quadrant the cosine will be negative

Sarah has been running a dog-walking business since 2010. She walks dogs twice a day, takes them to the park, and returns them t

Contact [7]

For A, you wanna look at $350 and $750 and find out how much her pay increased from 2010 to 2014.
For B, you want to create an equation (math problem) <span>to represent the fees that Sarah charges each year that would be reliant to your answer for part A. Hope this helps!
