Answer:
B
Step-by-step explanation:
cause when we substitute 5 in the equation we get 3<7which is true.
The max occurs when length=width
so
perimiter=16
and L=W
P=2(L+W)
16=2(L+L)
16=2(2L)
16=4L
4=L
the dimentions are length and width are 4 meters
aera will be 16 square meters
Answer:
Z + 12
Step-by-step explanation:
Z-(-12)
Z + 12
Double negative turns into positive
51,000
5 in the ten thousands,
The thousands value is 1, the hundreds is 4 (less than 5 so we round down)
The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
