The value of c is
Explanation:
Given that the trinomial is
We need to determine the value of c such that the trinomial is a perfect square.
The value of c can be determined using the formula,
From the trinomial, the value of b is given by
Substituting the value of b in the above formula, we have,
Squaring both the numerator and denominator, we have,
Thus, the value of c is which makes the trinomial a perfect square.
<h3>This cylinder is 8 inches tall and has a volume of 200 π in³. Find the area of the cross section.</h3>
Answer: cross section = 25π in²
Step-by-step explanation:
Cylinder volume is the product of the cross section by height.
Then cross section = cylinder volume/height = 200 π in³/8in = 25π in²
Answer: 25π in²
log₉(<em>x</em> - 7) + log₉(<em>x</em> - 7) = 1
2 log₉(<em>x</em> - 7) = 1
log₉(<em>x</em> - 7) = 1/2
Take the base-9 antilogarithm of both sides; in other words, make both sides powers of 9:
can also be written as √9 = 3, and
, so the equation reduces to
<em>x</em> - 7 = 3
Solve for <em>x</em> :
<em>x</em> = 10
