The equation of the circle with the given center and radius is x²-2x+y²+10y-74=0.
The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.
The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²
Given that, the center of a circle is (1, -5) and the radius is 10 units.
Now, equation of a circle is
(x-1)²+(y+5)²=10²
x²+1-2x+y²+25+10y=100
x²-2x+y²+10y+26=100
x²-2x+y²+10y-74=0
Therefore, the equation of the circle with the given center and radius is x²-2x+y²+10y-74=0.

Answer:
yeah i think so
Answer:
Null hypothesis:
Alternative hypothesis:
Comparing the p value with the significance level given we see that so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can say that we don't have significant difference between the two proportions.
Step-by-step explanation:
1) Data given and notation
represent the number college graduates with outstanding student loans currently owe more than $50,000 (tech start-ups)
represent the number college graduates with outstanding student loans currently owe more than $50,000 ( biotech firms)
sample 1
sample 2
represent the proportion of college graduates with outstanding student loans currently owe more than $50,000 (tech start-ups)
represent the proportion of college graduates with outstanding student loans currently owe more than $50,000 ( biotech firms)
z would represent the statistic (variable of interest)
represent the value for the test (variable of interest)
significance level given
2) Concepts and formulas to use
We need to conduct a hypothesis in order to check if is there is a difference in the two proportions, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We need to apply a z test to compare proportions, and the statistic is given by:
(1)
Where
3) Calculate the statistic
Replacing in formula (1) the values obtained we got this:
4) Statistical decision
Since is a two sided test the p value would be:
Comparing the p value with the significance level given we see that so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can say that we don't have significant difference between the two proportions.
a) Nhiều người yêu thương A. (Thay A bằng chính tên của em).
b) A yêu thương nhiều người. (Thay A bằng chính tên của em).
2) Phủ định hai phán đoán ở phần 1) (viết dưới dạng câu văn hoàn chỉnh).
The question involves using logical quantifiers to express the statements "Many people love A" and "A loves many people" and their negations. The formulas are ∃x (p(x, A)) and ∃y (p(A, y)) for the original statements, and the negations are ¬∃x (p(x, A)) and ¬∃y (p(A, y)).
The question involves expressing statements about relationships using logical quantifiers and then finding their negations. Given S as the domain of humans and p(x, y) representing the statement "x loves y", we can write the formulas for the following statements:
a) Many people love A: ∃x (p(x, A))
b) A loves many people: ∃y (p(A, y))
The negation of these statements can be written as:
a) It is not the case that many people love A: ¬∃x (p(x, A)), which means no one loves A or everyone does not love A.
b) A does not love many people: ¬∃y (p(A, y)), implying A loves no one or A does not love everyone.
