Can y’all please help !!!

Answer:

radius:5

center (2,-4)

Step-by-step explanation:

the equation of a circle is

(x-h)^{2}  + (y-k)^{2}  = r^{2}

where the center is (h,k) and the radius being r

this would mean that for your specific equation,

h=2

k=-4

and r=\sqrt{25} = 5

so in order to graph the circle you start at (2,-4) and measure the distance of 5 units on your compass and graph it!

The length of the hypotenuse of a right triangle is 137 units. The length of one leg of the triangle is 105. Gina wrote the foll
OLga [1]
A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88

Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88

If B = { p : p is a factor of 12 } list the elements of this set and find n ( B )​
anastassius [24]

Answer:

B={1,2,3,4,6and12}

n (B) =6

Step-by-step explanation:

<h3>Greetings !</h3>

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

Hope it helps!
