What is true about the function h(x) = x2 + 20x – 17? Check all that apply. The vertex of h is (–10, –117). The vertex form of the function is h(x) = (x + 20)2 – 17. The maximum value of the function is –17. To graph the function h, shift the graph of f(x) = x2 left 10 units and down 117 units. The axis of symmetry of function h is x = 20.

The vertex of h is (-10, -117) and To graph the function h, shift the graph of f(x)= x2 left 10 units and down 117 units are the correct answers

Step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

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:
