Calculate the quotient below and give your answer in scientific notation.<br> 2.64*10^-3\8.0*10^0

Zolol [24]

Answer:

The quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

Step-by-step explanation:

We need to find quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$

We know that $10^0=1$

Now solving:

$\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033$

Writing it in scientific notation

$0.00033\\=3.3\times10^{-4}$

So, the quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

What is the slope of (0,2) and (-8,-8)?

Doss [256]

Answer: 1.25

Step-by-step explanation:

Step 1: Slope is calculated as y2 - y1/ x2 - x1

Step 2: identify the coordinates, from the stated question, y2 = -8; y1= 2

x2= -8; x1=0

Step 3: slot in the values into the formula

slope= -8 - 2/ -8 - 0

slope = -10/ -8

slope= 1.25
