NASA launches a test rocket with an initial velocity of 211 meters per second from an initial height of 22 meters above sea-level. Find a quadratic function that models the height of the rocket, in meters above sea-level, as a function of time t
, in seconds after the launch. (HINT: 4.9 meters = 16 feet) Use your model to answer the following questions.

-6 is the correct option from the above given options

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

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:

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
