Answer:

arc = 5π units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here we have a semicircle with d = 10, so r = 5, then

arc = \frac{1}{2} × 2π × 5 = 5π units

Convert: 3 days = minutes
telo118 [61]

ANSWER

4320 minutes

EXPLANATION

To convert from days to minutes, first, we have to convert from days to hours. It is known that 1 day has 24 hours, so 3 days have,

3\text{ }days\cdot\frac{24\text{ }hours}{1\text{ }day}=72\text{ }hours

Then, we convert from hours to minutes. If 1 hour has 60 minutes,

72\text{ }hours\cdot\frac{60\text{ }minutes}{1\text{ }hour}=4320\text{ }minutes

Hence, there are 4320 minutes in 3 days.

The product of 2 consecutive odd integers is 1 less than 4 times their sum. A quadratic function models this situation. What is
Ilia_Sergeevich [38]
<span>Let the 2 consecutive odd integers be represented by:
 "x" and "(x+2)
_________________
The product of these two consecutive odd integers is:
________________
</span>→  <span>x*(x + 2); or, write as: x(x + 2)
__________________
The sum </span>of these two consecutive odd integers is:
<span>________________________________
</span>→  <span>x + (x + 2) = (2x + 2)
_______________________________
The product of 2 conductive integers, "</span>x(x + 2)" , is 1 less than 
   4 times their sum, "(2x + 2)".
<span>______________________________
</span>→  Write as: 4*(2x + 2) − 1 = x(x + 2)
<span>________________________________
Note the distributive property of multiplication:
_______________________________
</span>→  <span>a*(b + c) = ab + ac ;
________________________________
We have: 
___________
</span>→  4*(2x + 2) − 1 = x(x + 2)
<span>_____________________________
</span>      → 4*(2x + 2) = (4*2x)  + (4*2) = 8x + 8
<span>____________________________________
On the "right side of the equation; we have:
______________________________________
</span>→  x(x + 2) = (x*x) + (x*2) = x² + 2x
<span>_____________________________________
We can rewrite the equation:
__________________________
</span>→  4*(2x + 2) − 1 = x(x + 2) ;
<span>___________________________
by substituting our obtained "expanded values" for:
   "[</span>4*(2x + 2)]" ; and for: "[x(x + 2)]" ;
<span>______________________________________
</span>→  4*(2x + 2) − 1 = x(x + 2) =
____________________________
         →  8x + 8 − 1 = x² + 2x ;
__________________________________
→ Simplify the "+8 − 1" on the "left-hand side" of the equation to "7"; and subtract "2x" from EACH SIDE of the equation:
<span>____________________________________
</span>→  8x + 7 − 2x = x² + 2x − 2x ; to get:
<span>____________________________
</span>       → 6x + 7 = x² ;
________________________________
→To solve for "x";  Subtract "6x" and subtract "7"; from EACH SIDE of the equation; to get an equation in "quadratic format" ; that is:
<span>_____________________________________________
ax

let x and x+2 be the consecutive odd integers. Their product is x(x+2) Their sum is x + x+2 or 2x+2 x(x+2)=4(2x+2)-1 Domain is odd integers</span>
