Whenever there's a division sign you always TAKE AWAY.
So for the first one you would do 5- -3... Which is 8
This would leave you with the answer x^8
For the second one, I worked out a first:
3- - 1 = 4
So a would be a^4
Then I worked out b:
2- - 3= 5
So b would be b^5
And the final answer to question would be a^2b^5
Hope this helps :)
Answer:
a = 6.92820323 units
c = 2.828427125 units
Step-by-step explanation:
<u>Triangle one solution:</u>
<u />
= sin 60
a = 8 × sin 60 = 6.92820323 units
<u>Triangle two solution:</u>
<u />
= cos 45
c = 4 × cos 45 = 2.828427125 units
Answer:Yes
Step-by-step explanation:Look for it
Answer:
Step-by-step explanation:
<u>Let the depreciation rate is x per year, then we have:</u>
- 28000*x² = 22000
- x² = 22000/28000
- x² = 0.7857
- x = √0.7857
- x = 0.8864
<u>Exponential function for this case is:</u>
- V(t) = 28000*0.8864^t, where V(t) - future value, t- number of years
<u>Value of the car after 3 years:</u>
- V(3) = 28000*0.8864^3
- V(3) = 19500
