Consider the table below that represents a quadratic function.

zlopas [31]

It would be -1/2 because the formula to find slope (rate of change) is (y2-y1)/(x2-x1) and in this case it would be (4.5-2)/(-3--2) which simplifies to (2.5)/(-5) which is -1/2

A cone and a cylinder have equal radius, r, and equal altitudes, h. If the slant height of the cone is l, then the ratio of the

77julia77 [94]

Given:

radius of cone = r

height of cone = h

radius of cylinder = r

height of cylinder = h

slant height of cone = l

Solution

The lateral area (A) of a cone can be found using the formula:

$A\text{ = }\pi rl$

where r is the radius and l is the slant height

The lateral area (A) of a cylinder can be found using the formula:

$A\text{ = 2}\pi rh$

The ratio of the lateral area of the cone to the lateral area of the cylinder is:

$\pi rl\text{ : 2}\pi rh$

Canceling out, we have:

$\begin{gathered} =\frac{\pi rl}{2\pi rh} \\ =\text{ }\frac{l}{2h}\text{ or l:2h} \end{gathered}$

Hence the Answer is option B

The path followed by a roller coaster as it climbs up and descends down from a peak can be modeled by a quadratic function, wher

Romashka [77]

Answer:

$y = -0.1x^2 + 250 ft$

Step-by-step explanation:

Because this quadratic equation would have the curve-down form of:

$y = -ax^2 + b$

where a and b are positive coefficient.

If we let the peak (250 ft) of the curve be at x = 0. Then

$y = -a0^2 + b = 250$

$b = 250$

Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have

$-a(\pm 50)^2 + 250 = 0$

$-a2500 = -250$

$a = 250/2500 = 0.1$

Therefore, the model quadratic equation of our path would be

$y = -0.1x^2 + 250 ft$

What is the value of f(3) in the function f(x)=5/6x+8

natita [175]

For this case we have a function of the form $y = f (x)$ , where $f (x) = \frac {5} {6} x + 8$

We must find the value of the function when $x = 3$ , that is, we must find f (3). So:

$f (3) = \frac {5} {6} (3) + 8\\f (3) = \frac {15} {6} +8\\f (3) = \frac {5} {2} +8\\f (3) = 2.5 + 8\\f (3) = 10.5$

So $f (3) = 10.5$

Answer:

$f (3) = 10.5$
