The Garcia family is building a rectangular pool and wants to lay 1‘ x 1‘ tiles around the perimeter of the pool. They want the pool to be 8 feet wide but they haven’t decided yet how long it should be. They would like the pool to be at least 16 feet long but given the size of the backyard the maximum length is 22 feet.

its 4 because 2 times 2 is 4, if you double the number two you get four

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:

answer: 0.1,0.85

step-by-step explanation:

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
