Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is 
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
Answer:
The total cost is <em>28.26.</em>
Step-by-step explanation:
The radius of the birdbath is <em>1.25 feet.</em>
The cost per foot is <em>3.6</em> .
<em>The formula for perimeter of circle is given by,</em>
<em>= 2πR , where R is the radius of circle.</em>
Inserting the above value of radius in the equation above,
circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 
Thus the total cost is,
= (7.85)(3.6) = 28.26
Answer:
C. x^14
Step-by-step explanation:
(x^9)^0 is 1
(x^7)^2 is x^14
x^14*1 is x^14
The Answer is C. x^14

From the information given, we don't know how much each potato weighs. All we know is that when you add up all 5 of them you get one kilogram.
If all five have exactly the same weight then it's 200 grams.
