Answer:
Step-by-step explanation:
let th numbers be x and y.
x+y=21
y=21-x
Product P=xy=x(21-x)=21 x-x^2
P'=21-2x
P'=0 gives 21-2x=0,x=21/2
P"=-2
which is less than 0 at x=21/2
so P is greatest at x=21/2
y=21-21/2=21/2
P=21/2 ×21/2=441/4=110.25
Step-by-step explanation:
we have
length =8in
breadth =6in
since . The length and width of the actual flower bed will be 24 times larger than the length and width in the drawing.
new
length=8×24=192in
breadth =6×24=144in
(b) What is the perimeter of the actual flower bed ? Show your work.
<em>answer:the perimeter of the</em><em> </em><em>actual flower bed</em><em> =2(l+b)</em>
<em> =2(l+b)=2(192+144)=672</em><em>in</em>
(a) What is the perimeter of the drawing? Show your work
<em>answer</em><em> </em><em>:</em><em> </em><em>the perimeter of the </em><em>drawing</em>
<em>=</em><em>2</em><em>(</em><em>8</em><em>+</em><em>6</em><em>)</em><em>=</em><em>9</em><em>6</em><em>in</em>
<em>(c) What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 24? Show your work</em>
<em>p</em><em>e</em><em>r</em><em>i</em><em>m</em><em>e</em><em>t</em><em>e</em><em>r</em><em> </em><em>o</em><em>f</em><em> </em><em>flower </em><em>bed</em><em> </em><em>/</em><em>p</em><em>e</em><em>r</em><em>i</em><em>m</em><em>e</em><em>t</em><em>e</em><em>r</em><em> </em><em>o</em><em>f</em><em> </em><em>d</em><em>r</em><em>a</em><em>w</em><em>i</em><em>n</em><em>g</em>
<em>=</em><em>9</em><em>6</em><em>/</em><em>6</em><em>7</em><em>2</em><em>=</em><em>1</em><em>/</em><em>7</em>
<h3>
<em>perimeter</em><em> </em><em>of</em><em> </em><em>drawing</em><em> </em><em>is</em><em> </em><em>increased</em><em> </em><em>by</em><em> </em><em>7</em><em>t</em><em>i</em><em>m</em><em>e</em><em>s</em><em> </em><em>of</em><em> </em><em>perimeter</em><em> </em><em>of</em><em> </em><em>flower</em><em> </em><em>bed</em></h3>

To do the comparison, we'll use the following temperatures:
Day 1: 5°F
Day 2 : 1.5°F
Comparison of Day 1 and Day 2:

or

Comparison of days with absolute value:

or

3.
The temperature that's the closest to 0 during the week is -0.5°F. Using absolute value, we can see that the distance from 0°F to -0.5°F is the smallest of all the temperature measurements.
4.
The temperature that's the farthest to 0 during the week is 5°F. Using absolute value, we can see that the distance from 0°F to 5°F is the biggest of all the temperature measurements.
5.
The coldest temperature is -4°F. This is the value that is farthest to the left of 0°F on the number line.
6.
The warmest temperature is 5°F. This is the value that is farthest to the right of 0°F on the number line.

you should start with one subject and finish them up. then move on to the next subject. dont switch subjects and focus. youll get them all sooner if you pay attention. dont cheat!
Answer:
The biased exponent is used for the representation of negative exponents. The biased exponent has advantages over other negative representations in performing bitwise comparing of two floating point numbers for equality. The range of exponent in single precision format is -128 to +127.
