Answer:
x = 3.1 ft
Step-by-step explanation:
Use Pythagoras' Theorem to find the base of the triangle. The base of the triangle is half of 'x'. Let's call the base 'y' for now.
To find 'y' we must use this formula,
'c' is the hypotenuse, the longer side, and 'b' is the other short side.
Sub in the numbers for 'c' and 'b',
= 2.45
Square root both sides to get 'y' by itself,
y = 1.5652.....
Remember that 'y' is half of x? Simply multiply 'y' by 2 to get an answer for 'x',
x = 1.5652.... x 2
= 3.1 ft (1 d.p. nearest tenth)
Hope this helped!!
Answer:
r = - 4
Step-by-step explanation:
Given
- 1.5(4 - r) = - 12 ( divide both sides by - 1.5 )
4 - r = 8 ( subtract 4 from both sides )
- r = 4 ( multiply both sides by - 1 )
r = - 4
<span>The answer should be set up like so:
3125 = 3200*(d)^3
3125/3200 = d^3
3-root (3125/3200) = d
d = 0.992125657...
1 - d = 0.007874...
Therefore it depreciates at about 0.8% monthly
To find the depreciation 6 months from now, or 9 months from the beginning:
v = 3200 (d)^9
= 2980.232239...
So after 9 months the car would be about $2980.23</span><span>
