A glow stick contains a glass vial with chemicals. When the glow stick is bent, the vial breaks and the chemicals react to produce a glow. A science student observes that a glow stick kept in the freezer glows for a
longer duration than a glow stick kept at room temperature. What conclusion can be drawn based on the
observation? Be sure to note the outcome and test variables in the conclusion.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

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:

hey there : ) your answer would be a.
