<h3>Part A</h3>

As per the given information there are 4 different price intervals.

<u>Let x be the age and y be the admission price, then we have following equations;</u>

  • y = 10.50,     if   15 ≤ x ≤ 61
  • y = 8.50,      if    x ≥ 62
  • y = 6.50,      if   2 ≤ x ≤ 14
  • y = 0,           if   0 ≤ x ≤ 1

Help pls need help show your solution and then graph​
Stella [2.4K]

Answer:

Step-by-step explanation:

We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.

ax^2 + bx + c

so

a=4

b=-9

c=2

you can try it by hand or use this:

https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)

so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

Step-by-step explanation:

Circumference (C):

C = 2\pi r = 2\pi(5\:\text{ft}) = 31.4\:\text{ft}

Area (A):

A = \pi r^2 = \pi(5\:\text{ft})^2 = 78.5\:\text{ft}^2

Factor the polynomial: – x3 - 4x2 - 5x
Alinara [238K]

Answer:

-x3-4x2-5x=-x(x^2+4x+5)

Step-by-step explanation:

we are given the polynomial as

-x3-4x2-5x

here we can see that the GCF of -x^3 , -4x^2 and -5x is

-x

Hence we take it outside the bracket

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

The polynomial within the bracket x^2+4x+5 can not be factorized further , hence this would be our final answer.
