The strength of a rectangular beam varies
aleksandrvk [35]

Answer:

  • 1296 pounds per square inch

Step-by-step explanation:

<u>Direct variation equation:</u>

  • y = kx

<u>In this case it is:</u>

  • y = kx², where y- strength, x- depth of the beam, k- coefficient

<u>Substitute the given values and solve for k:</u>

  • 3600 = k*10²
  • 3600 = 100k
  • k = 3600/100
  • k = 36

<u>The equation becomes:</u>

  • y = 36x²

<u>Now, find the value of y, when x is 6:</u>

  • y = 36*6² = 1296

<u><em>Note, I took the depth as 6 inches but the question is a bit confusing by saying "four six inches". If it is 4 inches then your answer will be:</em></u>

  • y = 36*4² = 576

Expand.<br> Your answer should be a polynomial in standard form.<br> -p^2(p^2-p-1)=
kiruha [24]

Answer:

Step-by-step explanation:

Use distributive property. Then use exponent law.

Exponent law used here = a^{m}*a^{n}=a^{m+n}

-p^{2}(p^{2} - p - 1) = -p^{2}*p^{2} - p *(-p^{2}) - 1*(-p^{2}) \\\\= -p^{4} + p^{3}+p^{2}
