I suggest you using for those problems!
Answer: <em>The slope is 1 </em>
Step-by-step explanation:
(0, 2.7) - x1, y1
(1, 3.7) - x2, y2
3.7 - 2.7 = 1
1 - 0= 1
1/1 = 1
Answer:
Step 3: Choice D
Step 5: Choice B
Step 6: Choice A
Step 8: Choice C
(I saw in the top left corner of the picture that this is for Algebra II. I am in 8th grade, currently taking geometry, and I haven't taken Algebra II yet, but I <em>did</em> take Algebra I last year. I am 95% sure this is correct but if it isn't, the I sincerely apologize.)
Diameter of a semi circular garden = 18 feet
Radius of the garden :



Thus, the radius of the semi circular fence = 9 feet
We know that :

Which means, the circumference of Mary's semi circular garden :

(pi value = 3.14)


Thus, the circumference of fence needed for the semi circular garden = 28.26 feet
28.26 can be rounded off to 28.30 and 28.30 is the same as 28.3
Thus, Mary's reasoning is correct.
Therefore, Mary's reasoning is correct which means she needs 28.3 feet of fence to surround her garden.
What?? I am very sorry, but this is confusing.
