Answer:
Perimeter = 12
Area = 8
Step-by-step explanation: For the perimeter add all the sides so the top and bottom is both 2 so 2+2 = 4.
For the sides its both 4 so 4 + 4 = 8.
8 + 4 = 12
So the perimeter is 12.
For area just count all the blue squares and there is 8 squares.
So the area is 8.
Hope this helps you.
Answer:
see explanation
Step-by-step explanation:
(a)
A horizontal line parallel to the x- axis has equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 2, 4) with y- coordinate 4, thus
y = 4 ← equation of horizontal line
(b)
A vertical line parallel to the y- axis has equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 4) with x- coordinate - 2, thus
x = - 2 ← equation of vertical line
The areas can be estimated by adding the function values at the midpoints of the intervals 3–4 and 4–5. Those midpoints are x = 3.5 and x = 4.5. Hence we can approximate the area by adding f(3.5) and f(4.5). That is what is done in the attachments.
Top to bottom, the functions have approximate areas on the interval of ...
... 80, 77.5, 13.4, 50.5, 37.6, 58.325
Of course, the same graphing calculator can do numerical integration and give you the "exact" area (to 10 significant figures or better). The problem statement asks for this approximation, which is actually good enough for the purpose of ordering the values.
See the first attachment for results. See the other two attachments for area estimates and curve definitions (color key).
Answer:
f(x)= 1.38x
y= 1.38x
Step-by-step explanation:
basically the cost= 1.38 per pound
you can use cost=1.38x if ur grade level isn't at f(x) yet
<3
No. Marianne is not correct.
2x and -x are like terms. -x has a coefficient of 1.
together they would add 2x + -1x = x.
