A water tank is being filled so that the height of the water
doubles every 10 seconds. Initially, there is 4 inches of
water in the tank.
Estimate the water height after 31 seconds.

There would be approximately 124 inches of water after 31 seconds

Step-by-step explanation:

The reason it is 124 is because it starts off with 4 inches and it doubles every ten seconds so you would multiply 4 and 31 giving you the answer.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

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:
