Suppose that the functions s and t are defined for all real numbers x as follows. s(x)= x+6
t(x)= 4x2
write the expressions for (s. t)(x) and (s-t)(x) and evaluate (s+t)(-3).

Step-by-step explanation:

Given functions are:

We have to find:

(s.t)(x) => this means we have to multiply the two functions to get the result.

So,

Also we have to find

(s-t)(x) => we have to subtract function t from function s

Also we have to find,

(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x

Putting x = -3

Hence,

50.6

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:
