Answer:
Step-by-step explanation:
<u>This a form of the proportional relationship:</u>
- f(x) = kx, where f(x) - total cost, k- cost of each item, x - number of items
<u>We have:</u>
<u>It means:</u>
- Total cost of 5 cupcakes is $12
Step-by-step explanation:
you would divide 489 by 10 and then times that number by 15 and the divide 20 and get your answer that way
For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides.
<span>2x^2 + 3x + 0=0 </span>
<span>a=2, b=3, c=0 </span>
<span>b^2-4ac (In the next step just plug in your variables) </span>
<span>3^2 - 4(2)(0) </span>
<span>9 - 8(0) </span>
<span>9 - 0 </span>
<span>Your answer=9</span>
The fifth square root as in a^(1/2)^(1/2)^(1/2)^(1/2)^(1/2)
Well that is equal to a^((1/2)^5) or a^(1/32)
Since a=x^16 in this case and the rule (b^a)^c=b^(a*c) we have:
(x^16)^(1/32)
x^(16/32)
x^(1/2) or if you prefer
√x
