Slope-int form: y=mx+b
1. substitute the slope and x and y points in the equation. 3=-3/4(8)+b
2. simplify the equation. 3=-6+b
3. isolate the variable to solve for the y-intercept. b=9
4. substitute the slope and y-intercept to get the final equation. y=-3/4x+9
feel free to message me if there are any questions!

Help pls!?!?!?!!! This is algebra 2

Tresset [83]

$\boxed{\sf a_n=\dfrac{(-1)^n}{5n}}$

a:-

$\\ \sf\longmapsto a_1=\dfrac{(-1)^1}{5(1)}$

$\\ \sf\longmapsto a_1=\dfrac{-1}{5}$

$\\ \sf\longmapsto a_1=-5$

b:-

$\\ \sf\longmapsto a_4=\dfrac{(-1)^4}{5(4)}$

$\\ \sf\longmapsto a_4=\dfrac{1}{20}$

c:-

$\\ \sf\longmapsto a_{30}=\dfrac{(-1)^{30}}{5(30)}$

$\\ \sf\longmapsto a_{30}=\dfrac{1}{150}$

d:-

$\\ \sf\longmapsto a_{19}=\dfrac{(-1)^{19}}{5(19)}$

$\\ \sf\longmapsto a_{19}=\dfrac{-1}{95}$

Give the number of significant figures in this number: 40.00

Angelina_Jolie [31]

Answer:

Step-by-step explanation:

All the zero behind the four is also counted as a significant figure. As it is behind a number. If the number is 00.04 There will be only one significant figure. I don't know if I'm correct or not XD

A single microvillus is a rod-like structure that is 1.0 μm in height. it has a hemispherical top approximately 0.1 μm in diamet

andre [41]

The surface area of the cylinder that forms the "sides" of the microvillus rod is given by the area of the curved surface of a cylinder with diameter (d) = 0.1 μm and height (h) = <span>1.0 μm.

The curved surface area of a cylinder is given by 2πrh, where r = d / 2 = 0.1 / 2 = 0.05 </span><span>μm.

Thus, the curved surface area is given by

$2(3.14)(0.05)(1.0) = 3.14 \times 10^{-11}\mu m^2$

Therefore, </span>the surface area of the cylinder that forms the "sides" of the microvillus rod is $3.14 \times 10^{-11}\mu m^2$
