Answer:
172.7 sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
Insert the radius and height to derive SA, then multiply by 10 for the total number of fenceposts.
SA= 2(3.14)(.5)(6)
Calculate
SA=14.39166
Then multiply by 12
The result is 172.7 sqft
Hope this helps!
Answer:
Answer choice C. 
.
Step-by-step explanation:
The entire question is present in the attached figure.
It is established that
The function f(x) is represented by
,
indicating a parabola that opens upward.
The vertex is situated at the point (0,0).
The function g(x) shares the same parabolic shape.
The vertex of g(x) is located at (-3,1).
Therefore,
The transformation from f(x) to g(x) can be described as:
(0,0) transforms to (-3,1).
(x,y) transforms to (x-3,y+1).
This indicates a shift of 3 units to the left and 1 unit upward.
Thus,
The equation for g(x) in vertex form can be expressed as
.
To find the original number where 65% equals 1105:
0.65x = 1105
x = 1105 ÷ 0.65
x = 1700... hence, the original number is 1700.
Calculating 82% of 1700:
0.82 * 1700 = 1394 <== this is your answer.
The formula to calculate the difference between two standard deviations of populations n1 and n2 is:
sigma (difference)=√(sigma1/n1 + sigma2/n2). For this scenario:
sigma(d)= √(49/100 + 36/50)
Thus, the calculated standard deviation of the difference equals 1.1.
The sequence ABC is oriented clockwise in both diagrams, indicating an even number of reflections or a rotation.
A 90° clockwise rotation about the point (-3, -3) would accomplish the necessary transformation, but that is not a listed option. An equivalent action is...
• reflect across the line x = -3
• reflect across the line y = x
