Cameron sells more bottles of water. He extends the grid and plots the point (10, 20) in the coordinate plane above. What do the coordinates (10, 20) mean in this situation? A. Cameron sells 10 bottles of water for $2.

B. Cameron sells 10 bottles of water for $20.

C. Cameron sells 20 bottles of water for $10.

D. Cameron sells 20 bottles of water for $20.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

shorter then the tree
