Answer:
D.
Width = 11 yards
Length = 15 yards
Step-by-step explanation:
P = 2(l + w)
Consider the width to be x.
The length would then be x+4.
We know that P = 52 yd
52 = 2(x + x + 4)
52 = 2(2x + 4)
52 = 4x + 8 (Subtract 8 from both sides)
44 = 4x (Divide both sides by 4)
x = 11
The width is x, so the width is 11 yards.
The length is x+4, so the length is 15 yards.
Answer:
176.625 sq.ft, 4.8 sq.ft
Step-by-step explanation:
Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.
First list all the positive and negative factors of the constant term in the expression: ±(1,2,3,4,6,12) these will be the values for "p"
Second list all the positive and negative factors of the leading coefficient:
±(1,3) these will be the values for "q"
Now list all the possible values of

these will be the possible rational zeros of the polynomial function:
±(

)
these can be reduced to the following list:
±(1,

, 2,

, 3, 4,

, 6, 12
This list represents the possible rational zeros of the function. You can then use synthetic division to narrow down the actual roots of the function.
