Answer:

He can cut 15 1/2 meter strips.

Step-by-step explanation:

10 1/2 meter strips are 5 meters in length.

5 1/2 meter strips are 2.5 meters in length.

5 + 2.5 = 7.5 meters in length

15 care plans audited; 2 missing.<br> What is the percentage that are there?
skelet666 [1.2K]
2 out of 15 is 13.33333333, which is 13 1/3 so if you subtract 100 and 13 1/3 you get 86 2/3.

86 2/3% of the plans are there.

Function 2
balandron [24]

Answer:

Function 2 has larger max value.

Step-by-step explanation:

We know that the graph of Function 1 has the maximum value of 1 at x = 4 by looking at the graph.

But since we don't know what the maximum value of Function 2 is (Because Function 2 isn't given as a graph but rather an equation.) which means that we have to find the maximum value of Function 2.

\large{f(x) =  -  {x}^{2}  + 4x + 1}

It is not necessary to find x-value for a function because we want to know which function has larger maximum value. We will be using the formula below.

\large \boxed{y =  \frac{4ac -  {b}^{2} }{4a} }

As you may know, a max-min value is indeed y-value. From Function 2, we know the value of a, b and c from standard form y = ax²+bx+c

Substitute our a, b and c in the formula.

\large{y =  \frac{4( - 1)(1) -  {(4)}^{2} }{4( - 1)} } \\ \large{y =  \frac{ - 4 - 16}{ - 4} } \\ \large{y =  \frac{ - 20}{ - 4}  = 5}

Since our maximum value or y-value is 5 for Function 2. Since we also know that Function 1 has 1 as maximum value and Function 2 has 5 as maximum value. Therefore, Function 2 has larger maximum value.

A relation is a function if it has only One y-value for each x-value. Functions f(2/3)=2/9 for f(x)=2x²-4x+2 and f(1/4)==-21/4 for  f(x)=4x²+2x-6

<h3>What is a function?</h3>

A relation is a function if it has only One y-value for each x-value.

The given function is

f(x)=2x²-4x+2

Put x=2/3

f(2/3)=2(2/3)²-4(2/3)+2

=2(4/9)-8/3+2

=8/9-8/3+2

=(8-24+18)/9

f(2/3)=2/9

Now f(x)=4x²+2x-6

Put x=1/4

f(1/4)=4(1/4)²+2(1/4)-6

=4/16+2/4-6

=1/4+1/2-6

= 1+2-24/4

f(1/4)==-21/4

Hence functions f(2/3)=2/9 for f(x)=2x²-4x+2 and f(1/4)==-21/4 for  f(x)=4x²+2x-6
