Answer:

 

Are the pencils side by side or are they 2 x 2?

 

If they are side by side, then the band like a rectangle

but two of the sides are rounded.

 

In that case, The length is 10x 4 = 40.

The width is a half circle with diameter 10, which has

a circumference (perimeter) of 1/2*PI*10 = 5 * pi.

 

The total length of the band is 2*40 + 2*5*pi = 80 + 10*pi

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is t
qwelly [4]

Given:

The growth of a sample of bacteria can be modeled by the function

b(t)=100(1.06)^t

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

b(t)=100(1.06)^t

Here, b(t) number of total bacteria after t hours.

Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

b(t)=100(1.06)^3

b(t)=100(1.191016)

b(t)=119.1016


Therefore, the number of total bacteria after 3 hours is 119.1016.

Find the length of each arc. Round your answers to the nearest tenth. r = 40 =24use 3.14 for π
liraira [26]

Answer:

1.7 units

Explanation:

The length of an arc is calculated using the formula below:

l=\frac{\theta}{360\degree}\times2\pi r

Substitute the given values of θ and r:

\begin{gathered} l=\frac{24\degree}{360\degree}\times2\times3.14\times4 \\ =1.674 \\ \approx1.7\text{ units (to the nearest tenth)} \end{gathered}

The length of the arc is 1.7 units.
