Answer:
radius:5
center (2,-4)
Step-by-step explanation:
the equation of a circle is
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=
= 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!
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
the answer should be 1/5 because its one out of all the five choices
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!
