the utility industry has 428.5 thousand jobs in 2010 and is expected to decline at an average rate of 3 thousand jobs per year f

Aleksandr-060686 [28]

Answer: 7%

Step-by-step explanation:

Given: Initial jobs = 428.5 thousand

Average rate of declining of jobs from 2010 to 2020 = 3 thousand jobs per year

From 2010 to 2020 , there are 10 years.

Total jobs declines till 2020 = 10 x (3 thousand)

= 30 thousand (Change in jobs)

Now, utilities percent change for 2010 to 2020 : $\dfrac{change \ in \ job\ numbers}{Initial\ jobs}\times 100$

$=\dfrac{30}{428.5}\times100\\\\\approx7.00\%$

Utilities percent change for 2010 to 2020 = 7 %

Given that cosA = -8/17 and sinA is negative, determine the value of tanA.

borishaifa [10]

Answer:

tan A = -15/8.

Step-by-step explanation:

sin^2a = 1 - cos^2A

= 1 - (-8/17)^2

= 225/289

So sin A= 15/17

tan A = sin A / cos A

= 15/17 / -8/17

= 15/-8

= -15/8.
