solmaris [256]

Answer:

y = 240000 x e^(0.078 x t)

Step-by-step explanation:

This is exponential growth, so the power at the exponential function will be positive ( negative is for exponential decay.) Since it is increasing by 7.8 percent exponentially we can write an exponential function relating y with t.

Use the FOIL method to find the product. (x - 8)(x + 3)

Sliva [168]

Greetings and Happy Holidays!

FOIL stands for: First Outside Inside Last

FOIL is the order in which you would multiply (distributive property) the different terms:
$(x - 8)(x + 3)$

Multiply the First terms $(x)(x)$ :
$=x^2$

Multiply the Outside terms $(x)(3)$ :
$=x^2+3x$

Multiply the Inside terms $(-8)(x)$ :
$=x^2+3x-8x$

Multiply the Last terms $(-8)(3)$ :
$=x^2+3x-8x-24$

Simplify the expression:
$=x^2-5x-24$

The Answer Is:
$\boxed{=x^2-5x-24}$

I hope this helped!
