Answer:
x = 3.5; perimeter = 59; area = 8
Step-by-step explanation:
isosceles means the two legs equal each other so use same expression later on
6x + 8 = 2x - 6
6x - 2x = -8 - 6
4x = -14
x = 3.5
plug x value in the first expression to find the two sides that are equivalent to each other
6(3.5) + 8
21 + 8
29
plug x value into the second expression (the base)
2(3.5) - 6
7 - 6
1
perimeter = side 1 + side 2 + side 3
perimeter = 29 + 29 + 1
perimeter = 59
area = base × height/2 or bh/2
first plug in x value into height expression
4x + 2
4(3.5) + 2
14 + 2
16
area = 1 × 16/2
area = 16/2
area = 8
Answer:
Exterme Value: .
The bird reaches its minimum height which is 4ft affter covering a horizontal distance of 2 ft.
Step-by-step explanation:
The given function is .
We add and subtract the square of half the coefficient of x.
.
The first three terms form a perfect quadratic trinomial.
.
This function is now written in the form , where (h,k) is the extreme value(vertex).
The extreme value or the vertex is .
Interpretation:
The bird reaches its minimum height which is 4ft affter covering a horizontal distance of 2 ft.
43 + 39 = 82
82 - 40 = 42
Your blank is 42.
Answer:
Step-by-step explanation:
Number of Newspaper Published in a day = 300,000
Each news paper must include a Comic section. To check whether each newspaper has comic section or not, the publisher must make a sample Size of 500 or 1,000 will be good . That is , the publisher has to check between Sample size of either 600 or 300 newspapers ,whether it contain a comic section or not.
So, Just Taking a newspaper from a sample size of 600 or 1500 newspapers or 500 or 1000 newspaper and then checking whether it contains Comic section or not will be best way that publisher can adopt.
Time must be kept in mind by the publisher while choosing the sample size.
