Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or
fenix001 [56]

Answer:

The function has a negative leading coefficient and a maximum vertex point

Explanation:

This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.

This function's end behavior is Down and Down, so it must have a negative leading coefficient.

The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.

This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.

This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.

The longest side of a triangle is 3 in. longer than the shortest side. The medium side is 2 in. longer than the shortest side. I
Olenka [21]

s = length of the shortest side of the triangle

m = length of the medium side of the triangle

l = length of the longest side of the triangle

(you can use different variables like l, w, h, x, y.......)

Perimeter(P) of a triangle is the total sum of the sides, in this case:

P = s + m + l

You know:

P = 26in

l = s + 3     [longest side is 3in longer/more than(addition) the shortest side]

m = s + 2   [medium side is 2in longer than the shortest side]

To find the lengths of the three sides, you can do this:

P = s + m + l         Substitute/plug in what you know. So plug in 26 into "P" since P = 26, plug in (s + 3) into "l" since l = s + 3, and plug in (s + 2) into "m" since m = s + 2

26 = s + (s + 2) + (s + 3)     Combine like terms (like terms have the same variable and power/exponent)

26 = 3s + 5   To find "s", isolate/get the variable "s" by itself. Subtract 5 on both sides

21 = 3s      Divide 3 on both sides to get "s" by itself

7 = s        

Now that you found s, you can use it to find the other sides

m = s + 2          Substitute/plug in 7 into "s" since s = 7

m = 7 + 2

m = 9

l = s + 3    Plug in 7 into "s"

l = 7 + 3

l = 10

The longest side is 10 inches, the medium side is 9 inches, the shortest side is 7 inches

PROOF

P = s + m + l

P = 7 + 9 + 10

P = 26 inches

Answer:

\frac{1}{2}u-3u

Step-by-step explanation:

'one-half u subtracted by 3 times u'

The mathematical expression for the statement can be translated as = \frac{1}{2}u-(3\times u) =\frac{1}{2}u-3u
