How is the formula for the circumference of a circle derived? Drag and drop the correct word into each box to complete the expla

n200080 [17]

Answer:

diameter

circumference

$\pi$

diameter

Step-by-step explanation:

First, find the length of the diameter (d) and the length of the circumference of the circle (c).

Next, divide the length of the circumference c by the length of the diameter d and set up an equation

$\dfrac{c}{d}=\pi$

where the ratio equals to $\mathbf{\pi }$ (the definition of $\pi$ )

Then, solve the equation for the circumference c:

$c=\pi d$

Finally, substitute 2 times the radius for the diameter

$c=\pi \cdot 2r=2\pi r$

Log(5x-4)-log(×+1)=log4

Anna007 [38]

Answer:

x = 8

Step-by-step explanation:

log(5x-4)-log(x+1)=log 4

log [ (5x - 4) / (x+ 1) ] = log 4

[ log (a/b) = loga - logb]

(5x - 4 ) / ( x + 1) = 4

(5x - 4) = 4x + 4

5x - 4x = 4 + 4

x = 8

Hope it will help :)❤

Solve the equation -25+4y=35

borishaifa [10]

-25+4y=35
*Subtract 35*
-25+4y-35=0
*add 25 (to cancel out)*
4y-35=25
*add 35 (to cancel out)*
4y=60
*Divide by 4 to get y on its own*
y=15
Hope this helps :)

Graph a line with a slope of 3/4 that contains the point (2,-3).

mel-nik [20]

Answer:

Start at the y-intercept (0, -4.5) and then use rise over run (Up 3 and right 4)

Step-by-step explanation:

y - y1 = m(x - x1)

y + 3 = 3/4(x - 2)

y + 3 = 3/4x - 3/2

y = 3/4x - 9/2
