y = kx for a proportional relationship

12 = k*5

divide each side by 5

12/5 = k

y = 12/5 x

if x=8

y = 12/5 * 8

y = 96/5

y = 19 1/5

The volume of a cylinder is 81 pi in^3 and the height of the cylinder is 1 in. What is the radius of the cylinder

ladessa [460]

Answer:

18/20π

Step-by-step explanation:

81π ÷ 1 = 81π

81π ÷2 = 18/20π

You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.

The graph below shows a quadratic function f(x) and an absolute value function g(x)

Sophie [7]

Answer:

The x-values that are approximate solution of the equation $f(x) = g(x)$ are $x_{1} \approx -3.5$ and $x_{2}\approx 5$ , respectively.

Step-by-step explanation:

From graph we infer that the x-values that represents a solution to the system of equations corresponds to those values of x in which both functions coincide. As we see, there are two x-values for $f(x) = g(x)$ , which are described below:

$x_{1} \approx -3.5$ and $x_{2}\approx 5$

The x-values that are approximate solution of the equation $f(x) = g(x)$ are $x_{1} \approx -3.5$ and $x_{2}\approx 5$ , respectively.

At a concert, the number of security guards needed is based on the average density of people in an area of 25'x25' called a bloc

ira [324]

find total area by multiplying 350' x 200' = 70,00 sq ft

area of one block, multiply 25' x 25' = 625 sq ft = area for one Security guard

divide area for one security guard into total area of facility 70,000 / 625 =

112 security guards

find how many people for each block = 70,000 / 625 = 112 blocks

12,000 people divided by 112 blocks = 12,000 / 112 = 107.14 rounded to nearest 10 = 110 people per block
