Answer:
Number A is correct I think, coz if uu take the feet convert them into decimals u'll get accurate answers
Answer:
Is that the full question? I think some of it is missing.
Answer: P ( 3/2, - 1 )
Step-by-step explanation: the formulae that defines the midpoint of a line is given below as
x = (x2 + x1)/2 and y = (y2 + y1)/2
Where x and y are the coordinates of the mid point.
Point A is (-1, 5) hence x1 = - 1 and y1 = 5
Point B is (4, -3) hence x2= 4 and y2 = - 3
For x coordinate, we have that 4 + (-1)/2 = 4 - 1/ 2 = 3/2
For y coordinate, we have that - 3 + 5 / 2 = - 2/2 = - 1
Hence, coordinate of midpoint is P ( 3/2, - 1 )
Answer:
y=3(x+3)^2-8
Step-by-step explanation:
Vertex form:
y=a(x-h)^2+k
h=-3, k=-8
y=a(x+3)^2-8
sub (-4,-5)
-5=a(-4+3)^2-8
a=3
y=3(x+3)^2-8
Answer:
QM = 7 cm
Step-by-step explanation:
Tangents to a circle from an external point are congruent.
The perimeter (P) is the sum of the sides of the triangle, that is
PL + LQ + QM + MR + RN + NP = 42
6 + LQ + QM + 8 + 8 + 6 = 42
LQ + QM + 28 = 42 ( subtract 28 from both sides )
LQ + QM = 14
Since LQ = QM , then
QM = 7
