8(1+tan^2x)+4tan^2x-12=0.
8+12tan^2x-12=0
12tan^2x=4
tanx=1/sqrt(3)
x=atan(1/sqrt(3))
x=0.5236

13. Write a rule for the linear function in the table.
dalvyx [7]

Answer:

(x)= 2, 5, 8, 11

Use the formula  

a n  =  a 1  +  d  ( n  −  1 )

to identify the arithmetic sequence.

a n  =  3 n  −  1

f(x)= 5, 11 17, 23

Use the formula  

a n  = a 1  +  d  ( n − 1 )

to identify the arithmetic sequence.

a n  =  6n  −  1

x      f(x)

2      5

5      11

8      17

11      23

Nothing further can be done with this topic. Please check the expression entered or try another topic.

2 ,   5 ,   8 ,   11  

5 ,   11 ,   17 ,   23

Step-by-step explanation:

Write a rule for the linear function in the table.

x;     f(x)

2      8

5     17

5      11

11    23

A; f(x) = x + 5

B;f(x) = x + 1

C;f(x) = 2x + 1

D;f(x) = –2x – 1

If all your solutions are  

A; f(x) = x + 5

B;f(x) = x + 1

C;f(x) = 2x + 1

D;f(x) = –2x – 1

None of the above will work with the data set you have presented.

the volume of the prism is 1122 cubic inches. use the formula V = BH to find the h of the prism. B= 93.5in.
Crank
V = Bh  ⇒  
h = V/B = 1122 / 93.5 = 12 inches.
