How does tan 135 degrees compare to tan -135 degrees

1 answer:

3 0

Evaluating the tangent function for the two values we obtain the following:
tan 135=tan(135+180)=tan 315=-1

next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive

Amir buys a new car for £16470. The value of the car will depreciate by 2% each year. Work out how much amir's car will cost aft

Ronch [10]

Answer:

Amir's car will cost £10348.88 after 23 years.

Step-by-step explanation:

I finally found a UK human!

This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.

The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.

16470 × $0.98^{23}$ = £10348.88

I hope that helps you!! ^-^

Kenny’s weight is 6/7 times Melvin’s weight.

Mazyrski [523]

Answer=7:13

Kenny's Weight*6/7=Melvin's Weight

So, for example, if Melvin's weigh was 7...

Kenny's Weight*6/7=7

divide both sides by 6/7

Kenny Weight=6

So we can say that Melvin's weight to Kenny's weight is 7:6

The boys total weights would be...

7+6=13

So Melvin's weight over the total weight of the two boys is:

7:13
