Answer:
no
Step-by-step explanation:
because 0-2 is -2 so,
-1 and -2 are not equal
<h3><u>Answer:</u></h3>
- <u>x </u><u>-</u><u> </u><u>8</u>
<h3><u>Solution</u><u>:</u></h3>
We are given a rectangle with one of its sides ( length ) equal to ( x - 7 ) Meters.
- Also we are given the area of the rectangle as x² - 15x + 56 square meters .
We have to find the expression for another side of the rectangle i.e it's width
We will use the formula of area of rectangle to find the expression :
- <u>A</u><u>rea </u><u>=</u><u> </u><u>length </u><u>×</u><u> </u><u>width</u>
Therefore,
ㅤㅤ➝ A = l × w
ㅤㅤ➝ x² - 15x + 56 = ( x - 7 ) × w
ㅤㅤ➝ x² - 8x -7x + 56 = ( x - 7 ) × w
ㅤㅤ➝ (x² - 8x )( - 7x + 56 ) = ( x-7 ) w
ㅤㅤ➝ x( x - 8 )-7( x - 8 ) = ( x - 7 )w
ㅤㅤ➝ ( x - 8 )( x - 7 ) = ( x - 7 )
ㅤㅤ➝ ( x - 8 )w = ( x - 8 )( x - 7 )
ㅤㅤ➝ w = ( x - 8 )( x - 7 ) / ( x - 7 )
ㅤㅤ➝ <u>w = ( x - 8 )</u>

200 / 5 = 40
answer
p >= 40
11)
$15 per hour
so
15p >= 200
solve for p
p >= 200/15
p >= 13.33 or p?= 13 1/3
minimum hours = 13.33 or 13 1/3
Answer:
Rate of change per hour in the number of bacteria is r=0.28
Step-by-step explanation:
Given : There are 16 bacteria in a beaker and four hours later there are 228 bacteria in the beaker.
To find : What is the rate of change per hour in the number of bacteria.
Solution :
At initial number of bacteria is 16
After 4 hours number of bacteria is 228
Rate of change per hour is given by
where A = total number of bacteria, P = initial number of bacteria, r= rate of change , t= time
Taking log both side,
Therefore, Rate of change per hour in the number of bacteria is r=0.28
