The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.

Hope this helps!
Have a nice day :)

Find the volume of the composite figure below.
worty [1.4K]

Answer:

Volume of composit figure= 4834.14 cm^3

Step-by-step explanation:

here's your solution

=> Radius of hemisphere = 9 cm

==> volume of hemisphere = 2/3πr^3

==> volume of hemisphere = 2/3*22/7* 9^3

==> volume = 1526.04 cm^3

=> Radius of cylinder = 9 cm

=> Height of cylinder = 13 cm

==> volume of cylinder = πr^2h

==> volume of cylinder = 22/7*9^2*13

==> volume of cylinder = 3,308.1 cm^3

Volume of composit figure = 1526.04 + 3308.1

= 4834.14 cm^3

hope it helps

Can someone help me with this plsssss
cupoosta [38]

Answer:

15 cm

Step-by-step explanation:

Given:

The two cylinders shown in the figure are similar to each other.

Therefore, when two figures are similar their measures are in proportion.

So, radius and height of both the cylinders are in proportion.

Radius of both the cylinders are 2 cm and 5 cm respectively. Height of the smaller cylinder is 5 cm. Now,

\frac{2}{6}=\frac{5}{x}

Doing cross multiply, we get:

2x=6\times 5\\2x=30

Dividing both sides by 2, we get:

\frac{2x}{2}=\frac{30}{2}\\x=15\ cm

Therefore, the height of the larger cylinder must be 15 cm in order to make both the cylinders similar to each other.
