To solve this problem you must apply the proccedure shown below:

 1. The vertex i at <span>(0, 36) and a focus at (0, 39), then you have:

 a=36
 a^2=1296

 2. The directrix is:

 y=a^2=c
 c=39
 y=1296/39
 </span>y=432/13<span> 

 Therefore, the answer is the option D, which is: </span><span>D. y=± 432/13</span>

when a number is added to 1/5 of itself, the result is 24. the equation that models this problem is n 1/5 n = 24. what is the va
GuDViN [60]

Let n be unknown number, then 1/5 of this number is 1/5n. When you add these two numbers, you get

n+\dfrac{1}{5} n.

You know that this sum is equal to 24, so

n+\dfrac{1}{5} n=24.

1. Multiply this equation by 5:

5n+n=120.

2. Solve it:

6n=120,\\n=120:6,\\n=20.

Answer: n=20, correct choice is B.

Find f(1) if f(x)=2x^3+x^2-3x-1
luda_lava [24]

Answer:

The answer is -1

Step-by-step explanation:

f(x) = 2x³ + x² - 3x - 1  

f(1) = 2(1)³ + (1)² - 3(1) - 1

f(1)= 2 + 1 - 3 - 1

f(1)=3-3-1

f(1)=0-1

f(1)= -1

Thus the answer is -1 ....
