Answer:

  68°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation between the angle's adjacent side and the hypotenuse is ...

  Cos = Adjacent/Hypotenuse

This means ...

  cos(B) = a/c

  B = arccos(1/√7) ≈ 68°

A brand new truck was purchased for $45.000. A year later the truck was worth $40,480, and the year after that $35.622. If the r

Answer $32,045

Step-by-step explanation: Ok, to get the rate of depreciation all we we have to do is $45 divided by $40.480 you would get 1.1116.

The rate of depreciation: 1.1116

If you do $45,000 divided by 1.1116 you'll get 40,322.

It won't be the exact same answer because you would have to divide for an hour.

Now we can skip to the important part: $35,622 divided by 1.1116 = $32,045

Therefore the truck will be worth $32,045 in 10 years!

I hope this helped

Can someone help me find the answer to these 3 problems if so thank you .

Answer:

1. r+s²=49

2. pq²=24

3. -4xy-6x²+2x²y-6y= -54

Step-by-step explanation:

1. r+s²=0+7²=49

2. pq²=(6)(2)²=6(4)=24

3. -4xy-6x²+2x²y-6y= -4(3)(2)-6(3)²+2(3)²(2)-6(2)

                                = -24-6(9)+2(9)(2)-12

                                = -24-54+36-12

                                = -78+36-12

                                = -42-12

                                = -54

At 10 A.M the outside temperature was -5 F. By noon, the temperature was -17 F. Ricardo said that it was getting warmer outside.
