Answer:
Step-by-step explanation:
eq. of a parabola with vertex at origin and focus (a,0) is
y²=4ax
a=6
so y²=4×6×x
or y²=24 x
If I'm not mistaken its 7.2200
1/2 (12)(5a+7b)
6(5a+7b)
30a + 42b -- I hope this helped
Answer:
no solution
Step-by-step explanation:
Given
- v + 5 + 6v = 1 + 5v ← combine like terms on left side
5v + 5 = 1 + 5v ( subtract 5 from both sides )
5v = - 4 + 5v ( subtract 5v from both sides )
0 = - 4 ← not possible
Hence the equation has no solution
Answer: 8
Step-by-step explanation:
Let mammals be represented by y
There are three more reptiles than mammals in the habitat. Therefore, Reptiles = y + 3
There are seven fewer amphibians than mammals in the habitat. Therefore, amphibian = y - 7
y + y + 3 + y - 7 = 41
3y - 4 = 41
3y = 41 + 4
3y = 45
y = 45/3
y = 15
Since amphibian = y - 7
= 15 - 7
= 8
There are 8 amphibians
