A circular fence is being placed around a tree. The diameter of the fence is 4 feet. How much fence is used around the tree? Lea
Step2247 [10]

Answer:

8π

Step-by-step explanation:

If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.

The circumference of a circle is 2πr²

Just plug in the variables and you get 2π(2)² which is 8π

Hope this helps! :)

What is the equation of the lines that passes through the points (-2, -3) and (4, -5)?
antoniya [11.8K]
Since all the options are in the slope intercept form, we find the equation using the formula,

y = mx + c
We can find m, the slope using the formula,

m = \frac{ change \: in \: y }{change \: in \: x}
m = \frac{ - 5 - - 3}{4 - - 2}
m = \frac{ - 2}{6} = - \frac{1}{3}

On substitution,

y = - \frac{ 1}{3} x + c

We use any of the points, say (-2,-3) to determine the value of c.

- 3 = - \frac{1}{3} ( - 2) + c
c = - \frac{11}{3}

The equation is therefore,

y = - \frac{1}{3} x - \frac{11}{3}

The correct answer is D.

For the equation y = 3.5x and y= 25x + 40.50, x represent time in hours and y represents cost in dollars. Which equation is not
dem82 [27]

We are given equations y =3.5x and y=25x +40.50.

Where x represent time in hours and y represents cost in dollars.

We need to determine that which equation is not the equation of a proportional relationship?

In first equation we have slope 3.5 and y-intercept 0.

In second equation, we have slope 25 and y-intercept 40.50.

<em>In order to have a a proportional relationship, there should be y-intercept =0.</em>

<h3>Therefore, y= 25x + 40.50 is not the equation of a proportional relationship.</h3>

PLEASE HELP WILL GIVE BRAINLIEST<br> Answer all parts of the question please!
Schach [20]
A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A

B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches
