Answer:

Cant answer

Step-by-step explanation:

Depending on the option choices and without seeing the option choices I can give you an idea of how to solve this.

Using y=mx+b we can find the y intercept by knowing that B is the value of the y Intercept

Simplify the rational expression. state any restrictions on the variable. n^4-11n^2+30/n^4-7n^2+10

Andrej [43]

For this case we have the following expression:
 $\frac{n ^ 4-11n ^ 2 + 30}{ n ^ 4-7n ^ 2 + 10} 

$
 We are going to make the following change of variables:
 $x = n ^ 2
$
Rewriting the expression we have:
 $\frac{(x ^ 2-11x + 30)}{(x ^ 2-7x + 10)} 

$
Factoring the expression we have:
 $\frac{(x-5) (x-6)}{(x-5) (x-6)} 
$
Canceling similar terms we have:
 $\frac{x-6}{x-2} 
$
Returning the change we have:
 $\frac{n ^ 2-6}{n ^ 2-2} 

$
 The resctrictions of the function are those that make the denominator equal to zero.
We have then:
 $n ^ 2-2 = 0

n = +/- \sqrt{2} 
$
 Answer:
The simplified expression is:
 $\frac{n ^ 2-6}{n ^ 2-2}$
The restrictions are:
 $n = \sqrt{2} 
$
$n = - \sqrt{2}$

A square pyramid is shown below: What is the surface area of the pyramid?

Reptile [31]

Well first you would find the area of the square on the bottom
Which would be:
0.7*0.7= .49
Then we would find the area of one of the triangles on the side:
8*0.7= 5.6* 1/2= 2.8
Next, you will multiply the 2.8 by 4, because there are 4 triangles:
2.8*4=11.2
Finally add the 11.2 to the area of the square, and you'll have your answer.
.49+11.2= 11.69
So, B is your answer

A regular triangular pyramid has a base and lateral faces that are congruent equilateral triangles. It has a lateral surface are

TEA [102]

We know that

[lateral surface area of a regular triangular pyramid]=3*[area of one equilateral triangle]
so
[area of one equilateral triangle]=lateral surface/3-----> 81/3-----> 27 ft²

[surface area of the regular triangular pyramid]=lateral area+area of the base

area of the base is equals to the area of the lateral sides because are equilateral triangles

therefore
area of the base=27 ft²

[surface area of the regular triangular pyramid]=81+27----> 108 ft²

the answer is
the surface area of the regular triangular pyramid is 108 ft²
