Answer:
The equation of circle A with radius AC is , or in other words option d.
Step-by-step explanation:
If the radius of this circle is AC, then we can determine the distance between points A ( - 1, 4 ) and C ( - 5,1 ) to come to the length of the radius -
Distance between A and C =
=
= = = 5 units - Which is also the length of the radius of the circle.
So if the radius is given to be 5 in length, knowing that the general equation for a circle is ( where ( h, k ) is the center and r is the radius ) if the radius is 5, , and solution must be option b / option d.
Now if the radius is AC, the center point must be point A ( circle A ). Therefore point ( - 1, 4 ) is the center, and the equation of the circle must be the following -
= - and hence our solution is option d
Answer:
n + 24/n
Step-by-step explanation:
n = number
24/n = quotient
Expression: n + 24/n
The volume of the prism is:
V = Ab * h
Where,
Ab: base area
h: prism height
The area of the base is:
Ab = (1/2) * (B + b) * (htr)
Where,
B: major base
b: minor base
htr: height of the trapeze
Substituting values:
Ab = (1/2) * (5 + 2) * (3)
Ab = 10.5
Then, the volume is:
V = (10.5) * (10)
V = 105 cm ^ 3
Answer:
The volume of the right prism is:
V = 105 cm ^ 3
Well you can’t if you can’t figure out what x and y is then it’s an equivalent expression so x and y are 1
