Which situation can be represented by the equation Y equals 74X

Sidana [21]

Answer:

X: amount of a spare part of price $74 per unit.

Y: cost of purchasing X spare parts.

Step-by-step explanation:

We can imagine that X represents the amount of an object, for example a car spare part, which price is $74 per unit.

Then, Y would represent the cost of purchasing X units of that spare part.

Describe the change in the graph of the parabola f(x) when it transforms into g(x) =

saw5 [17]

Answer:

(d) The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).

Step-by-step explanation:

We assume you intend ...

f(x) = equation of a parabola

g(x) = 2/3·f(x)

Multiplying a function by a factor of 2/3 will cause it to be compressed vertically to 2/3 of its original height. When the function is a parabola, this has the effect of making it appear wider than before the compression.

The compression factor is positive, so points on the graph remain on the same side of the x-axis. The direction in which the graph opens is not changed.

The attachment shows parabolas that open upward and downward, along with the transformed version.

Dab likely has 11 - $10 bills and 1 - $5 bill to make $115 total. Any fewer $10 bills and he'd require more than 12 total bills to get $115.

How do you do this problem?

zhenek [66]

Answer:

A) g is increasing, and the graph of g is concave up.

Step-by-step explanation:

g'(x) = ∫₀ˣ e^(-t³) dt

Since e^(-t³) is always positive, ∫₀ˣ e^(-t³) dt is positive when x > 0. So the function is increasing.

Find g"(x) by taking the derivative using second fundamental theorem of calculus:

g"(x) = e^(-x³)

g"(x) is always positive, so the function is always concave up.
