517284 books have been sold to date.
Step-by-step explanation:
Given,
Copies sold in first month = 41900
This represents 8.1% of copies sold to date.
Let,
x be the number of copies that have been sold to date.
8.1% of x = 41900
Dividing both sides by 0.081
Rounding off to nearest whole number
x = 517284

These involve the rules for the power of a point. For questions 6-8, we use the theorem that the square of the length of the tangent is equal to the length of the secant multiplied by the length of its external segment.
6. 6^2 = (3)(x + 3)12 = x + 3x = 9 units
7. 4^2 = (2)(x + 2)8 = x + 2x = 6 units
8. 24^2 = (12)(x + 12)48 = x + 12x = 36 units
9. The included angle is half the difference of the larger and smaller arcs. Since the larger arc is 85 degrees, the smaller is 25 degrees, and the difference is 60. Half this difference is x = 30 degrees.
10. The angles at the intersection are vertical angles, so both equal to 65 degrees. Then the sum of the intercepted arcs must be equal to double of the vertical angle: 2 x 65 = 130 degrees. Since one is 95 degrees, the other is x = 130 - 95 = 35 degrees.
40 + 0.20m = 25 + 0.35m
40 - 25 = 0.35m - 0.20m
15 = 0.15m
15 / 0.15 = m
100 = m.....they will be the same at 100 miles
We know that
center (−1, 4) and <span>passes through the point (3, −5)
</span><span>the value for the radius is,
using the Distance Formula---------r=</span>√(4+5)²+(-1-3)²=√(9²+(-4)²
r=√97
<span>equation for a standard form for a circle
(x-h)</span>²+(y-k)²=r²
<span>the center is (h,k)-----------> (-1,4)
</span>(x+1)²+(y-4)²=(√97)²---------------> (x+1)²+(y-4)²=97
the answer is
(x+1)²+(y-4)²=97
