Owners of a recreation area are filling a small pond with water. Let y represent the total amount of water in the pond (in liter
devlian [24]

Answer:

  1. 32
  2. 400

Step-by-step explanation:

Lets start by defining the numbers in the equation.

This  equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same

In slope-intercept form,

  • m = slope or rate
  • and b = y-intercept

Th equation is y=400+32x so now we know

  • b=400
  • and m=32

For the first question the change per minute is the rate so it is <u>32.</u>

For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>

diamong [38]

Use:\\(h(x)\cdot g(x))'=h'(x)g(x)+h(x)g'(x)\\\\h(x)=x^3+2x+3\to h'(x)=3x^2+2\\\\g(x)=3x^3-6x^2-8x+1\to g'(x)=9x^2-12x-8\\\\f(x)=(x^3+2x+3)(3x^3-6x^2-8x+1)\\\\f'(x)=(x^3+2x+3)'(3x^3-6x^2-8x+1)+(x^3+2x+3)(3x^3-6x^2-8x+1)'\\\\=(3x^2+2)(3x^3-6x^2-8x+1)+(x^3+2x+3)(9x^2-12x-8)\\\\=9x^5-18x^4-24x^3+3x^2+6x^3-12x^2-16x+2+9x^5-12x^4-8x^3+18x^3-24x^2-16x+27x^2-36x-24\\\\=18x^5-30x^4-8x^3-6x^2-68x-22

f''(x)=(18x^5-30x^4-8x^3-6x^2-68x-22)'\\\\=90x^4-120x^3-24x^2-12x-68\\\\Answer:\ \boxed{-24}

Find the slope of a line perpendicular to 3x+y=15 ,-1/3, 5, -3, 1/3
Fittoniya [83]
So in the proper form, the equation would by y = 3x + 15. This means it has a slope of 3. Perpendicular lines have slopes that are negative reciprocals. The negative reciprocal of 3 (or 3/1) is -1/3.
