Answer:
A = 55.63 cm^2
Step-by-step explanation:
Let a,b,c be the lengths of the sides of a triangle. Heron's formula states that:
Area = √(p (p−a) (p−b) (p−c))
where p is half the perimeter, or
(a+b+c) / 2
So lets start by finding p:
(10.6 + 10.6 + 16) / 2
p = 18.6
Now lets substitute p and the other values into our equation:
A = √ (18.6 (18.6−10.6) (18.6−10.6) (18.6−16))
So let's plug this in to our calculators
A = √ (3095.04)
A = 55.633083682284 cm^2
The answer is a.
The formula for cylinder volume is (pi)(r^2)(h).
To find the volume of this cylinder, it is (pi)(2^2)(5)
That is (pi)(20)
or 20pi
The answer is a.
Answer:
The correct option is (4).
Step-by-step explanation:
The complete question is:
Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(275)?
- Houses sell on the market for an average of $275,000 and stay on the market an average of 275 days before being sold.
- Houses sell for an average of $275,000.
- f(275) indicates houses stay on the market an average of 275 days before being sold.
- f(275) represents the average number of days houses stay on the market before being sold for $275,000.
Solution:
The function f (p) is defined as the average number of days a house stays on the market before being sold for price <em>p</em> in $1,000s.
The function provided is: f (275)
That is, <em>p</em> = $275,000.
So, the function (275) describes the average number of days a house stays on the market before being sold for price $275,000.
Thus, the correct option is (4).
Use the quadratic formula -b+/-√b^2 -4(ac) / 2a
-4 +/- √(4^2 - 4(1*10) / (2*1)
X = -2 +/- i√6
