Ashipping company charges based on calculations of the volume of a rectangular box and the sum of the dimensions of the
box. a square rectangular prism has a side length represented by the linear function f(x), and a height represented by the
linear function g(x).

v(x) = (f f-g)(x) s(x) = (f+f+g)(x)

which statement describes the combined functions v(x) and s(x)?
the volume function is linear but the sum function is not
the sum function is linear but the volume function is not
both the volume function and the sum function are linear
neither the volume function nor the sum function is linear

B. The sum function is linear but the volume function is not

Step-by-step explanation:

We are given that f(x) and g(x) are linear. Due to this, the sum function S(x) is linear.

And we know the shape of our figure, so we just need to multiply the dimensions for V(x) but the product of three linear functions results in a cubic function, and we conclude V(x) is not linear.

Glad to answer.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
