A football player kicks a ball with an initial velocity of 47 feet per second. The initial height of the ball is 4 feet. The function h(t)=−16t2+47t+4 models the height (in feet) of the ball, when t is the time in seconds. What is the maximum height the ball reaches? Round to the nearest ½ foot. If no one catches the ball, how long will it be in the air? Round to the nearest second

true? is that what you're asking or do you mean something else?

something over 10 so ? /10

step-by-step explanation:

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:
