Answer:
196 gallon/minute
Step-by-step explanation:
Peter is filling a swimming pool with water
After a period of 7 minutes the pool is filled up with 1372 gallons
After 12 minutes the pool is filled up with 2352 gallons
Therefore the rate in gallon per minutes at which the pool is being filled can be calculated as follows
=( 2352-1372)/(12-7)
= 980/5
= 196 gallon/minute
Hence the pool is filled up at 196 gallon/minute
1.] multiplication of x squared by x yields a 3rd degree polynomial (having an x cubed term)
<span>2.] (x+3)^1/2 - 4 = x - 1 </span>
<span>(x+3)^1/2 = x + 3 </span>
<span>square both sides: x+3 = (x+3)^2 </span>
<span>simplify: x + 3 = x^2 + 6x + 9 </span>
<span>bring all terms to one side so that 0 = x^2 + 5x + 6 </span>
<span>factor the polynomial 0 = (x + 2) ( x + 3) </span>
<span>set each factor equal to zero & solve to get x = -2 and x = -3 </span>
<span>3.] x = 4 , not extraneous </span>
<span>4.] In mathematics, complex conjugates are a pair of complex numbers, both having the same real part, but with imaginary parts of equal magnitude and opposite signs. So -6 - 5i and -6 + 5i are complex conjugates. </span>
<span>5.] x = 8 and x = 9 </span>
<span>6.] x to the sixteenth twenty fifth power </span>
<span>x^4/5 * x^4/5 multiply exponents to get x^16/25 </span>
<span>7.] quantity of 80 minus 50 i over 39</span>
