Answer:
11.5% loss
Step-by-step explanation:
Discount = 25%
SP= 1425
MP= CP+18%
Profit or loss% - ?
---------
SP= MP- 25%= MP*0.75= 1425
MP= 1425/0.75= 1900
MP= CP+18%= CP*1.18
CP= MP/1.18= 1900/1.18 ≈ 1610.17
SP< CP, so there is loss
Loss%= (1610.17- 1425)/1610.17*100%= 11.5%
Please use " ^ " to denote exponentiation:
<span>(x - 2)^2 + (y + 3)^2 = 4</span>
<span>
</span>
<span>Test each point, one by one,to determine which coordinates satisfy the equation. For example, (0,0) results in (0-2)^2 + (0+3)^2 = 4, which in turn is 4 + 9, which does NOT equal 4. Reject (0,0). Move on to testing the other 3 points.</span>
Answer:
Step-by-step explanation:
From the given information:
The diagrammatic interpretation of what the question is all about can be seen in the diagram attached below.
Now, let V(x) be the time needed for the runner to reach the buoy;
∴ We can say that,
In order to estimate the point along the shore, x meters from B, the runner should stop running and start swimming if he want to reach the buoy in the least time possible, then we need to differentiate the function of V(x) and relate it to zero.
i.e
The differential of V(x) = V'(x) =0
=
squaring both sides; we get
By cross multiplying; we get

x = √(40²+12² - 2·40·12·cos(37°)) ≅ 31.3 units
Answer:
0.124
Step-by-step explanation:
To divide the numbers, we need to remove the decimal point
To remove decimal point , we multiply top and bottom by 100
Use long division. After using decimal point at the top we can include any number of zeros with 719
