Can someone help with this question

A police officer seals off the scene of an accident using a roll of yellow tape that is 272 feet long. What dimensions should be

klasskru [66]

Answer:

68 feet square

Step-by-step explanation:

The rectangle with the maximum area for a given perimeter is a square. The perimeter of a square is 4 times the side length, so the side length of the square area will be ...

(272 ft)/4 = 68 ft

_____

<em>More formally ...</em>

You can let x represent the length of one side. Then the length of the other side for the given perimeter will be 136 -x, and the area will be the product ...

area = x(136 -x)

The area function is a quadratic with zeros at x=0 and x=136. The vertex (maximum area) will be at the value of x that is on the line of symmetry between these points, at their midpoint: x = (0 +136)/2 = 68. This value of x makes the rectangle a square.

Find the range for the set of data 24, 30, 17, 22, 22

OverLord2011 [107]

$\huge\text{Hey there!}$

$\huge\textbf{Question reads....}$

$\text{Find the range for the set of data 24, 30, 17, 22, 22}$

$\huge\textbf{What does \boxed{range} mean in math?}$

$\boxed{Range}\rightarrow\text{is the DIFFERENCE between the biggest number and the}\\\text{smallest number.}$

$\huge\textbf{How do you find the \boxed{range}?}$

$\text{You find the biggest number \& subtract it from the smallest number.}$

$\huge\textbf{Equation:}$

$\text{24, 30, 17, 22, 22}$

$\huge\textbf{The \boxed{\mathsf{\mathsf{biggest}}} number }\huge\boxed{\downarrow}$

$\text{30}$

$\huge\textbf{The \boxed{\mathsf{\mathsf{smallest}}} number }\huge\boxed{\downarrow}$

$\text{17}$

$\huge\textbf{Equation:}$

$\rm{30 - 17}$

$\huge\textbf{Simplify it:}$

$\large\text{Start at 30 and go DOWN 17 spaces to the \boxed{left} and you will}\\\large\text{have your answer. }$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{13}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$

9 - T
10 - D
GARFIELD THE CAT

Step-by-step explanation:

Correct so far.

H -- 8

T -- 9

D -- 10

The balloon depicted ...

GARFIELD THE CAT

_____

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)^c = a^(b·c)

Of course, an odd number of minus signs in a product means the product is negative.

__

Most of these can be figured just by looking at the coefficient, or the exponent of one variable, such as x.

PLEASE HELP! Determine the slope & the y-intercept of the following graphs.

olga55 [171]

Hey girl! It's me again to explain this to you :)

Number 21.) If we start from our y-intercept -2 and move up 2 on our y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.

Slope: 2/1 or just 2

Y-intercept: -2

You didn't ask for this but i'm gonna write it anyways. The equation for this line is y=2x-2

Number 22.) If we start from our y-intercept 2 and move down 2 on your y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.

Slope: -2/1 or just -2

Y-intercept: 2

Again you didn't ask for this but the equation for this line is y=-2x+2

Hope this helped you understand and again make this brainliest and reply if you need more help or have any more questions :)
