Centre of circle = (-2, -3)
Equation of the circle:
( x - ( -2) )² + ( y - (-3) )² = (√2/4)²
(x + 2)² + (y + 3)² = 1/8 (Answer D)
Answer:
2
Step-by-step explanation:
gradient =y² -y¹ /x²-x¹
=9-1/2--2
=8/4
=2
Answer:
A
Step-by-step explanation:
Aquí, tenemos 2/3 como hombres.
La fracción de mujeres es, por lo tanto, 1-2 /3 = 1/3
Entonces 1/3 de 84 son mujeres Por lo tanto, el número de mujeres es 1/3 * 84 = 28
Answer:
1.83
Step-by-step explanation:
First, add the game and glasses. Write down the number you just got. Now, multiply by 0.15.
Take the second away from the first.
Now multiply that by 0.087
Finally, take 20 away
That is how much money you have spent.
Use both savings so they both get a huge meal.
In this type of calculations, we decompose 13 by checking the lowest powers of the base, that is 40. for example we check 40^2, or 40^3 and compare it to 85
Notice
40*40*40=64,000
so we check how many time does 85 fit into 64,000:
64,000/85=752.94
85*753=64,005; 64000-64,005=-5
this means that

thus

Answer: 10 (mod85)
Remark, the set of all solutions is:
{......-75, 10, 95, .....}, that is 85k +10
