Answer:

Larger cell 400 times bigger cell than the smaller cell

Step-by-step explanation:

Given:

diameter of the cell h = $8.76\times10^{-3}$

diameter of the cell v = $2.19 \times10^{-5}$

To Find:

How many tines larger is the bigger cell than the smaller cell?

Solution:

The cell h with diameter $8.76\times 10^{-3}$ is larger and the cell v with diameter $2.19 \times 10^{-5}$ is small. To find the number of times it is larger, we can divide the larger cell diameter by smaller cell diameter

=> $\frac{8.76\times 10^{-3}}{2.19 \times 10^{-5}}$

=> $\frac{8.76\times 10^ {-3} \times 10^{5}}{2.19 }$

=> $\frac{8.76\times 10^ {(-3+5)}}{2.19 }$

=> $\frac{8.76\times 10^2}{2.19 }$

=> $\frac{876}{2.19}$

=> 400

Larger cell is the bigger cell than the smaller cell by 400 times

Fill in the gaps in the arithmetic sequence -3, _ ,_ , _, _, _ 12

lord [1]

Answer:

-0.5, 2, 4.5, 7, 9.5

Step-by-step explanation:

The given terms are 6 apart, so the common difference is 1/6 of their difference:

d = (12 -(-3))/6 = 15/6 = 5/2 = 2.5

Add 2.5 to each term to get the next one. Then the sequence is ...

-3, -0.5, 2.0, 4.5, 7.0, 9.5, 12

By the fundamental theorem of calculus,

$\displaystyle \int_1^2 \frac1x \, dx = F(2) - F(1) = \ln|2| - \ln|1| = \boxed{\ln(2)}$
