The equation of a circle:
(h, k) - a coordinates of the center
r - a radius
Answer:
the center: (3, -2)
the radius: 3
Answer:
a = - 10
Step-by-step explanation:
Given
= - 2
a is divided by 2. The inverse operation to division is multiplication, thus
Multiply both sides by 5 to clear the fraction
a = 5 × - 2 = - 10
Answer:
See below
Step-by-step explanation:
- Initial Principal P₀ = 1000
- End of first period = 1000 + 1000*0.02/4 = 1005
- End of second period = 1005 + 1000*0.02/4 = 1010
- End of third period = 1010 + 1000*0.02/4 = 1015
- End of fourth period = 1015 + 1000*0.02/4 = 1020
You can either convert -3 into a fraction, or convert -2/5 into a decimal so you can solve this.
If you decide to convert -3, into a fraction, it would be -3/1, and you'd have to multiply that by the reciprocal of -2/5.
So, you'd have -3/1(-5/2)=15/2, which can be simplified to 7 1/2.
If you decide to convert -2/5 into a decimal, you would get -0.4. You would then divide -3 by -0.4, which is equal to 7.5.
Both 7.5 and 7 1/2 are correct answers, and if you were to convert 7.5 into a fraction and 7 1/2 into a decimal, you would notice that they are the same number, but in different forms.
