Slope = (y2 - y1) / (x2 - x1)
= (4 - -1) / (-1 - 4)
= 5/-5
=-1

A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the
Alexeev081 [22]

Answer:

Answer choice A) About 38.47 square units

Step-by-step explanation:

Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:

\dfrac{22}{2\pi}\approx 3.503

Since the area of a circle is \pi r^2, the area of this circle is:

\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47

Hope this helps!

write the eqaution in slope intercept form of the line that has a slope of 2 and contains the point (4,2)
GalinKa [24]
Slope intercept form:
y=mx+b
m=slope
b=y-intercept:

We Know the slope (m=2)and we have a point (4,2) then:
x₀=4
y₀=2
we have to find "b"
y=mx+b
2=2(4)+b
8+b=2
b=2-8
b=-6

Therefore:
if b=-6 and m=2; the equation in slope intercept form would be:
y=2x-6

<span>Answer: y=2x-6</span>

10 pounds of soil are needed to
Wewaii [24]

Answer:

40/3

Step-by-step explanation:

w = weight of soil needed

f = number of flower beds

a = constant value

w = a * f

<em>substitute</em>

10 = 6a

<em>simplify</em>

5/3 = a

w = (5/3)f

<em>plug in 8</em>

w = (5/3)(8)

<em>simplify</em>

w = 40/3
