8.4 * 10^1 is what I think the answer is
If sin Ф=1/3>0 and tan Ф<0; then Ф belongs to the second quadrant and cos Ф will be negative (cos Ф<0).
sin²Ф+cos²Ф=1
(1/3)²+cos²Ф=1
1/9+cos²Ф=1
cos²Ф=1-1/9
cos²Ф=8/9
cos Ф=⁺₋√(8/9)=⁺₋2√2 / 3
We have two possible solutions.
cos Ф=2√2 / 3 This solutions is not possible, because in this case cos Ф has to be negative (cos Ф<0)
cos Ф=(-2√2) / 3 this solutions is right.
answer:B. -2 square root 2 /3 (or (-2√2) /3 )
The <u>correct answers</u> are:
Unemployed people usually buy fewer things.
Unemployed people may not be able to repay their loans.
Unemployed people may have to to change their financial goals.
Explanation:
If someone is unemployed, they have much less money with which to purchase items, so they usually purchase less. This hurts the businesses that would profit from these purchases.
If someone is unemployed, their ability to pay their bills is affected since their income is gone. This means they may not be able to repay any loans they have in their name. This hurts the banks that have loaned the money.
If someone is unemployed, they may have to adjust their financial priorities. If they were looking to invest money, they no longer have it to invest. If they were looking to purchase real estate, again, they no longer have the money to do that. This hurts banks that they may invest through and the people or agencies that they would be purchasing real estate through.
Because the two triangles are similar, their angles will be the exact same.
Therefore, Angle B is 130 degrees
The answer is D.
There isn't a graph to look at for the second question so I can't help you on that one
May be there is an operator missing in the first function, h(x). I will solve this in two ways, 1) as if the h(x) = 5x and 2) as if h(x) = 5 + x
1) If h(x) = 5x and k(x) = 1/x
Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)
2) If h(x) = 5 + x and k (x) = 1/x
Then (k o h)(x) =k ( h(x) ) = k (5+x) = 1 / [5 + x]
