'Pi' ( π ) is the ratio of the circumference of a circle to its diameter.
The exact value of 'pi' can't be completely written with numbers, so whenever
we use 'pi', we always use an approximation.
Answer:
t ≥ -12
Step-by-step explanation:
Divide the inequality by the coefficient of t. Because that value is negative, the sign gets reversed.
(-4t)/(-4) ≥ (48)/(-4)
t ≥ -12
6m+23
You have to use distributive property, so 15x2=30 and 2x3m= 6m. You then subtract 30 from 7 and get 23.
Answer:
d=1.4
Step-by-step explanation:
cuz 10-1.4=8.6
<em><u>Answer</u></em>
c. It divides the radius by 2.
<em>Explanation</em>
The general equation of a circle is
(x-h)² + (y-k)² = r²
Where (h, k) makes the coordinates of the circle and r the radius.
x² + y² = 25 For this equation,
center (0, 0)
Radius = √25 = 5
4x² + 4y² = 25 First simplify this equation
4x² + 4y² = 25 ⇒ x² + y² = 25/4
center (0, 0)
Radius = √(25/4) = 5/2
The radius has been divided by 2
