REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
GalinKa [24]

Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Need help with question 7 and 8 with awnser please check photo for problems
Tanzania [10]

Answer:

7) 230mm

8) 98m

Step-by-step explanation:

7)

7x+8+6x+6+9x-4 =22x+10

if x is 10 mm, 22(10)+10 =230mm

8) perimeter of rec =2( l + w )

=2 ( 2x-5+2x+6 ) = 8x + 2

if x  is 12 metres, 8(12)+2 =98m

I’ll make you brainlist thankss

Answer:

The equation of the line will be:

  • y = 0

Step-by-step explanation:

Given the points

  • (0, 0)
  • (3, 0)

Finding the slope

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(3,\:0\right)

m=\frac{0-0}{3-0}

m=0

We know that the value of y-intercept can be obtained by setting x=0, and solving for y

Here,

at x = 0, the value of y = 0

Thus,

y-intercept = b = 0

We know the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

now substituting m = 0 and b = 0 in the slope-intercept form

y = mx+b

y = 0(x) + (0)

y = 0+0

y = 0

Therefore, the equation of line will be:

  • y = 0
