Answer:
Discontinuity at (−4, −3), zero at (−1, 0)
Step-by-step explanation:
The expression simplifies to ...

This is undefined at x=-4, hence there is a discontinuity there, and is zero for x=-1.
There is a discontinuity at x=-4, and a zero at (-1, 0).
Answer: C
Work:
1) Change the Mixed number into an improper fraction
3 x 8 = 24
1+24 = 25/3
2) Get both fractions on equal terms. Find the Greatest Common Denominator. In this case, it’s 24. Multiply by what you need to get 24. 8x3=24 and 12x2=24
3) Multiply Accordingly
25/8 x 3 = 75/24
7/12 x 2 = 14/24
4) Subtract and change back to Mixed Number
75-14 = 61
61/24 = 2 13/24
Answer:
6:5
Step-by-step explanation:
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
The algae is spherical in nature
Volume of the algae =4/3 pi r³
Volume of the algae = 4/3×pi×2.5³
Volume of the algae = 62.5/3 pi
Surface area = 4pi r²
Surface area = 4pi ×2.5²
Surface area = 25pi
Taking their ratio
surface area : volume ratio
= 25pi:62.5/3 pi
= 25 × 3/62.5
= 1.2
Hence the required ratio is 12/10 which is 6:5
