Answer:

<u>3(x^3 + 5x)^2 - 4 </u>   (please mark brainliest)

Step-by-step explanation:

plug g equation into x values of f equation

f equation = 3(x)^2 - 4

                        ^g goes here

So....

3(x^3 + 5x)^2 - 4

       ^ g goes here

Explain the error Tina says that 6:8 is equivalent to 36:64 what did tina do wrong
brilliants [131]
Tina said that 6:8 is equal to 36:64.
It's wrong. It should be 48:64. Because just like a fraction, whatever you multiply in the bottom, you do to the top.

The population of a small town in Alabama is 382 people. If the growth rate is 0.7%, what will its population be in 30 years?
goldenfox [79]
Formula for growth:

y = initial • (percent growth + 1)^time/frequency of growth

So, since initial population is 382

Percent growth is 0.007

The time is 30 years

And it goes it by .07% every 1 year,

y = 382 • (1.007)^30/1

y= 470.9203732 people

Since we can’t have 0.9 of a person, the population after 30 years will be 470 people.

Pavel [41]

132 in

Step-by-step explanation:

  • Take the total radius = 18+3 = 21= R (say)
  • Simply use the formula for the circumference i.e. 2*pi*R
  • 2*22/7*21= 132

The center of an ice rink is located at (0, 0) on a coordinate system measured in meters. Susan is skating along a path that can
Ganezh [65]
We are given:

the center of the rink at the origin.
A skating path (Susan): y = 6x - x^2 - 5
Starting point of Luke = (10, -21) 
Path (Luke) = quadratic eq'n with vertex at (8, -9)
Radius = 35 meters 


The solution that best interprets the path of the skaters is to substitute Luke's starting point to Susan's path or set-up a quadratic equation with vertex of (8,-9) and then equate to Susan's path to solve for their intersection.
