hours / views

1. / 125

2. / 250

3. / 375

4. / 500

5. / 625

2.

f(x)= 125 x views=125.hours

The slope of the function equals the visits of each hour.

3. (1;125) (2;250) (3;375) (4;500) (5;625)

4. "views as a function of hours"

5. in 12 hours the website will have f(12)=125 . 12 = 1500 views.

we can see in the plot that the line gets to that number for 8

mrs_skeptik [129]

Answer:

Option B.

Step-by-step explanation:

The given table of values is

x         f(x)

-3       -2

-2        0

-1         2

0         2

1          0

2        -8

3        -10

4        -20

We need to find the interval for which the function f(x) is positive.

From the given table it is clear that the value of function f(x) is negative before -2 and after 1.

The function positive between x=-2 and x=1. So, we can conclude that the function f(x) is positive for the interval (-2,1).

Therefore, he correct option is B.

Find the total surface area of this cone. Round to the nearest tenth.
leva [86]

Step-by-step explanation:

for given cone:

h = 3 ft, r = 3 ft

Let l be the Slant height of cone.

\therefore \: l =  \sqrt{ {h}^{2}  +  {r}^{2} }  \\  =  \sqrt{ {3}^{2} +  {3}^{2}  }  \\  =  \sqrt{9 + 9}  \\  =  \sqrt{2 \times 9}  \\   \therefore \: l= 3 \sqrt{2}  \: ft \\  \\ total \: surface \: area \: of \: cone \\  = \pi \: r(l + r) \\  = 3.14 \times 3(3 \sqrt{2}  + 3) \\  = 9.42 \times 3( \sqrt{2}  + 1) \\  = 28.26 \times (1.414 + 1) \\  = 28.26 \times 2.414 \\  = 68.21964 \\  \approx \: 68.2 \:  {ft}^{2}
