Equation of circle : (x-h)² + (y-k)² = R², where h and k are the coordinates of the circle and R, THE RADIUS
Center coordinates (5,-4), hence
(x-5)² + (y+4)² =R²
Now let's calculate R. Just replace x and y by the coordinates (-3,2)
(-3-5)² + (2+4)² = 10², so the Radius is equal to 10 and the final shape:
(x-5)² + (y+4)² = 100
ANSWER
50 food items
EXPLANATION
Tanya does not want to spend more than $250
The ticket costs $50 and each food item costs $4.
Let the number of items that can be bought be x.
So, the inequality that represents this situation is:
Now, let us solve it:
Tanya can buy not more than 50 items.
Answer: 30
Step-by-step explanation:
Since this is a right triangle, the pythagorean theorem says
So if you rearrange for you get
.
CAB=90 ABC=37 ACB=53. If we rotate a given triangle we’ll see that sides correspond to tiles of the floor.
Answer:
March he sells 51. April he sells 107
Step-by-step explanation:
In jan he made 14 so we double that for feb and have 28.
From that 28 he takes home 5 so we are left with 23.
Then we double 28 for March to get 56 but he takes 5 home which leaves 51 to be sold and so on.
