Answer: has a maximum

the maximum is 11

Step-by-step explanation:

f(x)= -5x^2-10x+6

the function f(x)= ax^2+bx+c=0 has a<0 so the equation has a maximum

I know V has the coordonate x=-b/2a, and y=-(b^2-4ac)/4a

b^2-4*a*c= (-10)^2-4*(-5)*6=100+120=220

so -b/2a=-(-10)/-2*5=+10/-10=-1 and

-(b^2-4ac)/4a=-220/4*(-5)=-220/-20=22/2=11

so V( -1, 11)

and the maximum is 11

natally needs to cut a pice of paper so that she has exactly 1/3 of it.if the length of the paper is 11 inches, how long will be

photoshop1234 [79]

Answer:

3 $\frac{2}{3}$ inches long

Step-by-step explanation:

Find how long the paper will be by dividing 11 by 3. This will find how much 1/3 of the 11 inch paper is.

11/3

= 3 $\frac{2}{3}$

So, if she cuts the paper, the paper will be 3 $\frac{2}{3}$ inches long

Represent the number 108 in expanded form and exponent

lubasha [3.4K]

<h3>Further explanation</h3>

Let's recall following formula about Exponents and Surds:

$\boxed { \sqrt { x } = x ^ { \frac{1}{2} } }$

$\boxed { (a ^ b) ^ c = a ^ { b . c } }$

$\boxed {a ^ b \div a ^ c = a ^ { b - c } }$

$\boxed {\log a + \log b = \log (a \times b) }$

$\boxed {\log a - \log b = \log (a \div b) }$

<em>Let us tackle the problem!</em>

$\texttt{ }$

$108 = 54 \times 2$

$108 = (27 \times 2) \times 2$

$108 = (9 \times 3) \times 2 \times 2$

$108 = (3 \times 3) \times 3 \times 2 \times 2$

$108 = 3^3 \times 2^2$

$\texttt{ }$

<h3>Conclusion:</h3>

The number 108 could be represented in expanded form and exponent as following:

$\boxed{ 108 = 3^3 \times 2^2 }$

$\texttt{ }$
