Write the equation for Chelsea's graph in

xeze [42]

Answer:

$y=-4x+16$ .

Step-by-step explanation:

From the given graph it is clear that the y-intercept is 16.

The line passes through (-2,24) and (2,8). So, slope of line is

$Slope=\dfrac{y_2-y_1}{x_2-x_1}$

$Slope=\dfrac{8-24}{2-(-2)}$

$Slope=\dfrac{-16}{4}$

$Slope=-4$

Slope intercept form of a line is

$y=mx+b$

where, m is slope and b is y-intercept.

Substitute m=-4 and b=16 in the above equation.

$y=(-4)x+(16)$

$y=-4x+16$

Therefore, the required equation is $y=-4x+16$ .

A cone's height is equal to the radius of its base. The area of its base is 1,386 square units. The approximate radius of the co

maxonik [38]

Answer:

21 units
9702 units³

Step-by-step explanation:

The area of the base is given by the formula ...

A = πr²

so the radius is ...

r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units

The volume is given by ...

V = (1/3)Bh

where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...

V = (1/3)(1386)(21) = 9702 . . . . cubic units
