(2t^2−t−8)(2t^2+2t−1)

= (2t^2+−t+−8)(2t^2+2t+−1)

= (2t^2)(2t^2) + (2t^2)(2t) + (2t^2)(−1) + (−t)(2t^2) + (−t)(2t) + (−t)(−1) + (−8)(2t^2) + (−8)(2t) + (−8)(−1)

=4t^4+4t^3−2t^2−2t^3−2t^2+t−16t^2−16t+8

=4t^4+2t^3−20t^2−15t+8

Sorry if I made it too complicated

Find the value of each variable
kondaur [170]

Answer:

The correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Step-by-step explanation:

Points to remember

The angles of a right angled triangle, 30°, 60° and 90° then sides are in the ratio, 1: √3 : 2

<u>To find the value of variables</u>

From the figure we can see 2 right angled triangle with angle 30, 60 and 90

we get, d= 5 then b = 5√3

b = 5√3  the c = 5√3 * √3 = 15

and a = 2 * 5√3 = 10√3

Therefore the correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Which graph represents the piece wise- defined function f(x) =​
Vanyuwa [196]

Answer:

<h2>The fourth graph, from left to right, is the correct answer.</h2>

Step-by-step explanation:

The given piecewise function is

f(x)=\left \{ {{-x+4 \ ; \ 0\leq x

Notice that the domain of the function specifies that, from zero to three, the function represents a decreasing (because the variable is negative) straight line. When the function is defined from 3 to infinite, the function is a constant of 5.

<em>So, the right graph must shows first a decreasing line, where the initial point is solid and the final point is empty, as the fourth fraph (from left to right), then it must show a horizontal line with an initial point solid.</em>

<em />

Therefore, the fourth graph, from left to right, is the correct answer.
