Answer:
You first take the annual interest rate on your loan and divide it by 365 to determine the amount of interest that accrues on a daily basis. Say you owe $10,000 on a loan with 5% annual interest. You'd divide that rate by 365 (0.05 ÷ 365) to arrive at a daily interest rate of 0.000137.
Answer:
radians
Step-by-step explanation:
to convert degrees to radians
degrees × 
= 260 ×
= 26 × 
= 13 ×

The ship sails at 20 km / h.
So
20 km / h x 2 h = 40 km
The boat moves 40 km to the northeast.
Then, in the same way:
20 km / h x 1 h = 20 km.
The ship moves 20 km northwest.
We solve this problem using vectors. In this case, we must perform the sum of two vectors a and b
a) magnitude = 40 km and direction 20 degrees east
b) magnitude = 20 km and direction 10 degrees northwest
In Cartesian coordinates, these vectors are written as:
a) 40sin (20º) i + 40cos (20º) j = 13,68i + 37,59j
b) -20sin (10th) i + 20cos (10th) j = -3,473i + 19,70j
The displacement vector of the ship would be the sum of a + b
a + b = 10,207i + 57,29j Finally, the magnitude of the a + b vector will tell us how far the ship is
√(10.21² + 57.29²) = 58.92km
Answer: <em>x=-4</em>
Step-by-step explanation:
<em>-4x=16</em>
<em>Divide by -4 on each side to cancel it out</em>
<em>x=-4</em>
Answer:
Step-by-step explanation:
hello :
use pytagor-rule :
triangle ABC : (x+15)² =17²+y²....(*)
triangle BDC : y² = x²+8²....(**)
by (**) put the value of y² in (*) :
(x+15)² = 17²+x²+8²
x²+30x+15² = 17²+x²+18²
30x +225 = 289+64
30x = 128
x= 128/30
x= 64/15
put this value in (**) calculate y² ......continu
