The owners of a golf course hired a company to determine how many squirrels were living on their property. First, the company pu

muminat

Answer:

Squirrel population is 440 squirrels.

Step-by-step explanation:

It is given that there are 22 squirrels are marked.

Later the company returned and counted a total of 220 squirrels of which are marked were 11.

So, we can set up proportional equation to find the squirrel population.

Let squirrel population is x.

We can set up proportional equation as

$\frac{11}{220}=\frac{22}{x}$

Cross multiply

11 x=4840

Divide both sides by 11

x=440

Best estimate is 440.

Find an equation of the line perpendicular to y=4x+5 and that passes through the point (0,-1)

iragen [17]

Answer:

y = -1/4x - 1.

Step-by-step explanation:

y = 4x + 5

The slope of this is 4 so the slope of line perpendicular to this line = -1/4.

Using the formula y - y1 = m(x - x1):

y - (-1) = -1/4(x - 0)

y + 1 = -1/4x

y = -1/4x - 1.

Draw a diagram of the archway modeled by the equation y = -x2 + 5x + 24. Find and label the y-intercept and the

Delvig [45]

Answer:

Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.

Step-by-step explanation:

The graph that represents the equation $y = -x^{2} + 5\cdot x + 24$ is now sketched with the help of a graphing tool and whose representation is included in a file attached below. The point associated with x-intercepts are (-3, 0) and (8, 0) and the point associated with the highest point is (2.5, 30.25). The width of the archway at its base ( $\Delta x$ ) and the height of the archway at its highest point ( $\Delta y$ ) are, respectively:

$\Delta x = 8 - (-3)$

$\Delta x = 11$

$\Delta y = 30.25$

Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.
