Find a coterminous angle between 0 and 2 pi for each given angle. 191pi/45

Sedaia [141]

Check the picture below.

let's recall that 2π is a full go-around or namely a revolution

$\bf \cfrac{191}{45}\implies \cfrac{45+45+45+45+11}{45}\implies \cfrac{45}{45}+\cfrac{45}{45}+\cfrac{45}{45}+\cfrac{45}{45}+\cfrac{11}{45} \\\\\\ 1+1+1+1+\cfrac{11}{45}\implies \stackrel{\textit{and this more}}{\underset{\textit{2 go-around}}{\underset{\uparrow }{2+2}+\stackrel{\downarrow }{\cfrac{11}{45}}}}$

Quadrilateral abcd is a rhombus and points c, d, and e are on the same line. is quadrilateral abde a rhombus?

Step2247 [10]

No, because BC and BD are not the same lengths. If AB = BC, then AB and BD are not the same lengths -> ABDE is not a rhombus.

Given the function: f(x) = 2x3 - 3/2x, find f(-4).

Sergeu [11.5K]

Answer:

D) -122

Step-by-step explanation:

Given:

$f(x) = 2x^3-\frac{3}2x$

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

$f(-4)= 2\times(-4)^3-\frac{3}{2}\times(-4)\\$

By using PEDMAS we will solve for exponential function first we get;

Now we know that $(-4)^3=-64$

So we get;

$f(-4)= 2\times(-64)-\frac{3}{2}\times(-4)\\$

Now using PEDMAS we will solve division.

$f(-4)= 2\times(-64)-1.5\times(-4)$

Now using PEDMAS we solve multiplication.

$f(-4)= -128+6$

Finally by subtraction we get;

$f(-4)= -122$
