Answer:
The only reason mathematics is admirably suited describing the physical world is that we invented it to do just that. It is a product of the human mind and we make mathematics up as we go along to suit our purposes. ... Mathematics is not discovered, it is invented.
Step-by-step explanation:
Marcus shoes: 35.99(5.5%)= (about) $1.98(tax) so 35.99+1.98= 37.97
Tia shoes: 39.99(9%)= (about)3.60 (tax) so 39.99+3.60=43.59
However it’s 15% off so 43.59(15%)= 6.54 so 43.59-6.54= 37.05
The difference is 0.92
The central angle COA = 2 * angle at the circumference
m < COA = 2 * 80 degrees
Answer:
(x + 7)² + (y - 8)² = 49
Step-by-step explanation:
Circle Equation: (x - h)² + (y - k)² = r²
(h, k) is center
<em>r</em> is radius
Step 1: Define
h = -7
k = 8
r = 7
Step 2: Substitute
(x - -7)² + (y - 8)² = 7²
(x + 7)² + (y - 8)² = 49
1) start with (x-h)^2 + (y-k)^2 = r^2. Insert the given info: center at (-1,8) and radius 5:
(x+1)^2 + (y-8)^2 = 5^2 (answer)
