Answer:
Domain (Basically means the sets of values of x-axis).Hence, the set of values of domain is given by -3<domain<1. Meaning domain lies between values more than -3 and less than 1.
Range (Basically means the sets of values of y-axis). Hence, the set of values of range is given by -1<range<3. Meaning that range lies between values more than -1 and less than 3.
Function basically means the equation of the given circle. We know that equation of circle is given by;
(x-h)^2+ (y-k)^2 = r^2 [where (h, k) is the center of circle and r is the radius of circle]
From the figure,
(h, k)= (-1 ,1) and r= 2.
So, we can conclude that function is given by equation:
(x-(-1))^2 + (y-1)^2 = 2^2
(x+1)^2 + (y-1)^2 = 4.
<u><em>To cover a rectangular region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?</em></u>
<u><em></em></u>
<u><em>L=length=15.5 ft; W=width; A=area=>170.5 sq ft</em></u>
<u><em></em></u>
<u><em>L*W=>170.5 sq ft Divide each side by L</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>W=>170.5 sq ft/L</em></u>
<u><em></em></u>
<u><em>W=>170.5 sq ft/15.5 ft=>11 feet</em></u>
<u><em></em></u>
ANSWER: To cover at least 170.5 sq ft. the width must be at least 11 feet.

Answer:
0.749
Step-by-step explanation:
The probability that at least one of the three taken balls is blue is the inverse of the probability that none of the three taken balls is blue, aka all 3 of the taken balls are red. The probability of this to happen is
In the first pick: 13/20 chance of this happens
In the 2nd pick: 12/19 chance of this happens
In the 3rd pick: 11/18 chance of this happens
So the probability of picking up all 3 red balls is
So the probability of picking up at least 1 blue ball is
1 - 0.251 = 0.749
I think it would be the second answer but I’m not positive
