Hello,
The formula for finding the circumference of a circle is $2 \pi r$ where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius: $2 \pi 4=8 \pi$ . We are told to use 3.14 for $\pi$ so we get $8(3.14)=25.12$ . Therefore, the circumference is 25.12 meters.

What is the equation of a line that is parralel to 2x+3y=3 and passes through the point (3,-4)

svetoff [14.1K]

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

When you want to find the point that a line travels through, you always want to ignore the b value. Two lines are parallel if they have EXACTLY the same slope. Y-intercept does not matter.

Plug in the x and y in the equation

-4=-2/3(3)+b
-4=-2+b
-2=b

Equation: y=-2/3x-2

Crazy boy [7]

Lisa is measuring the depth of a well. She drops a ball from a height of h feet into the well and measures how long it takes the ball to hit the bottom of the well.

Polynomial = $-16t^{2}+ 0t + h$

where 0 is the initial speed and h is height it was dropped .

Now find depth of the well, when t = 3.5 seconds and h = 6 ft

$-16t^{2}+ 0t + h$ = $-16(3.5)^{2}+ 0(3.5) + 6$

= $-16\times 12.25 + 0 + 6$

= -196 + 6

= -190

So depth of the well is 190 feet (negative sign represents the depth, below the ground)
