Identify the center and radius of a circle with equation (x+4)^2+(y-2)^2=36

Answers

Answer 1

Answer: In the equation of a circle in the form (x-h)^2 + (y-k)^2 = r^2, (h,k) is the center and r is the radius.

So, the center of the circle is at (-4,2) with radius 6 units.

An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 334 people living in East Vancouver and finds that 43 have recently had the flu. Suppose that the epidemiologist wants to re-estimate the population proportion and wishes for her 95% confidence interval to have a margin of error no larger than 0.03. How large a sample should she take to achieve this?

Which expression is not equivalent to 6^3/6^6

Answers

The expression that is not equivalent to $6^3/(6^6)$ is $1/6^2$ (option A)

How to find the inequivalent expression?

The expression given is $6^3/(6^6)$

Using the law of exponent:

$(x^4)/(x^2) =x^(^4 ^- ^2^)$

$= x^2$

we can simplify the expression:

$(6^3)/(6^6) = 6^3^-^6$

Simplifying the exponent gives

$6^-^3$

This can also be expressed as a fraction:

$(1)/(6^3)$ or $(1)/(216)$

Comparing the options, we can see that the inequivalent expression is $1/6^2$ (option A)

The answer is C

a dog weighs 44 pounds the dog needs to lose 7 pounds to reach its ideal weight mikala wrote the equation x + 7 = 44 to represent this situation Kirk wrote the equation 44 - x = 7 what does the variable represent which equation is correct can you write another equation that represents the situation

Answers

x represents the ideal weight of the dog. The first equation is correct because the ideal weight increased by seven pounds equals 44, since he currently weighs 44 pounds and must decrease that by 7 to get the ideal weight. The second one is also correct because 44 minus the ideal weight is seven, since seven is given as the difference between 44 and the ideal weight.

Another equation would be x=44-7. This is because the ideal weight is 44 pounds minus the seven pounds the dog loses.
