The slope of a line perpendicular to another line is the opposite reciprocal of the slope of that line. Basically, the slopes of two perpendicular lines multiply to -1. The slope of this line is -1/5. To find the slope of a line perpendicular, we need to find out what number, multiplied by -1/5, would make -1. Or, we can take the opposite reciprocal (it's the same answer). This number is 5, so the slope of a line perpendicular to this line is 5.

Here we go ~
The general equation of ellipse is :

[ because it's a horizontal ellipse with centre at origin ]
so, let's equate given equation with the standard equation ~

se get :
As we know, length of minor axis is : 2b = 2 × 6 = 12 units
and, the smaller circle has diameter = 2b = 12 units
so, it's radius = 6 units ~
Now, let's write the equation of circle with origin as centre and radius = 6 units

[ h = 0, k = 0, since circle has centre at origin ]

Answer:
Ginny will cast 2525 spells
Step-by-step explanation:
The ratio of spells Luna casts to spells Ginny casts is:
Luna :4
Ginny :5
4 spells of Luna is equivalent to 5 spells of Ginny
1 spell of Luna is equivalent to 5/4 spells of Ginny
Luna casts 2020 spells
It means Ginny will cast
spells
i.e. Ginny will cast 2525 spells
Answer:
X= -13
Step-by-step explanation:
Answer:
48 months
Step-by-step explanation:
first take how much you need and add how much you want to leave, so 2500+500=3000. Then delete 600 from 3000, which will give you $2400. divide $2400 by 50 which gives you 48. it will take 48 months to get enough money to purchase a car at $2500 and leave $500 in the account.
