Answer:

- 81t² + 16

Step-by-step explanation:

Simply expand the equation by factoring

(9t-4)(-9t-4) factor out negative sign

= -(9t - 4) (9t +4)

= -(9t + 4) (9t - 4) recall a² - b² = (a+b) (a-b)

= - [ (9t)² - 4²]

= - ( 81t² - 16)

= - 81t² + 16

Answer:

2) -81t² +16

Step-by-step explanation:

(9t -4)(-9t -4) = (9t x -9t) + (9t x -4) + (-4 x -9t) + (-4 x -4)

= -81t² - 36t + 36t + 16

= -81t² + 16

EXPLANATION

The nth term of the sequence is given by

$U_n=a+(n-1)d$

Where

$a$

is the first term and

$d$

is the constant difference.

We were given that,

$a=6$

S we just need the common difference to write the nth term.

We can get that from another information given to us.

We were also given that the 4th term is 6. This gives the equation.

$a+3d=-6$

We substitute

$a=6$

to obtain

$6+3d=-6$

$2+d=-2$

This implies,

$d=-2-2$

$d=-4$

We substitute these values into the general formula to obtain,

$U_n=6+(n-1)\times-4$

This gives us,

$U_n=6+-4n+4$

$U_n=10-4n$

Hence the nth term of the sequence is,

$10-4n$

What is the domain of the following quadratic equation? <br> f(x)=2x^2+5x-7

julia-pushkina [17]

Domain is th enumbers you can use and not cause conflict (like dividing by 0 or something)

actually, the domain is all real numbers
there is no real value of x that will make us divide by 0 or take the square root of a negative number

domain is all real numbers
