It is a decimal answer if you used a calculater, and divided then got that answer, then try the same problems just switch the order that you put in the calculater, ex: if you divide 408÷1201 ,and then you get an answer like that, then you would divide it like 1201÷408
I hope this helped :)

Graph the function f(x)=6x^5+8x^4-7x^3-5x^2+10 by making a table of values.

Komok [63]

Answer:

Step-by-step explanation:

A fifth-grade polynomial requires a minimum of 6 different points to create an adequate graph. Let is $X$ the dominion of the polynomial, such that $0$ , $1$ , $2$ , $3$ , $4$ , $5$ $\in X$ . The values of the function for each value are calculated herein:

x = 0

$f(0) = 6\cdot 0^{5}+8\cdot 0^{4}-7\cdot 0^{3}-5\cdot 0^{2}+10$

$f(0) = 10$

x = 1

$f(1) = 6\cdot 1^{5}+8\cdot 1^{4}-7\cdot 1^{3}-5\cdot 1^{2}+10$

$f(1) = 12$

x = 2

$f(2) = 6\cdot 2^{5}+8\cdot 2^{4}-7\cdot 2^{3}-5\cdot 2^{2}+10$

$f(2) = 254$

x = 3

$f(3) = 6\cdot 3^{5}+8\cdot 3^{4}-7\cdot 3^{3}-5\cdot 3^{2}+10$

$f(3) = 1882$

x = 4

$f(4) = 6\cdot 4^{5}+8\cdot 4^{4}-7\cdot 4^{3}-5\cdot 4^{2}+10$

$f(4) = 7674$

x = 5

$f(5) = 6\cdot 5^{5}+8\cdot 5^{4}-7\cdot 5^{3}-5\cdot 5^{2}+10$

$f(5) = 22760$

The table is now presented:

x y

0 10

1 12

2 254

3 1882

4 7674

5 22760

Finally, the graphic is now constructed by using an online tool (i.e. Desmos). The image is included below as attachment.

Simplify the expression (-502) square root 0

Firdavs [7]

Answer:

$-502\sqrt 0 = 0$

Step-by-step explanation:

Given

$-502\sqrt 0$

Required

Simplify

$-502\sqrt 0$

----------------------------------------

$\sqrt 0 = 0$

----------------------------------------

So:

$-502\sqrt 0 = -502 * 0$

$-502\sqrt 0 = 0$

If cos x= 5/13 and sin x <0 find cos (x/2) and sin (2x)

taurus [48]

We know that

if cos x is positive
and
sin x is negative
so
the angle x belong to the IV quadrant

cos x=5/13
we know that
sin²x+cos²x=1-------> sin²x=1-cos²x------> 1-(5/13)²---> 144/169
sin x=√(144/169)-------> sin x=12/13
but remember that x is on the IV quadrant
so
sin x=-12/13

Part A) <span>cos (x/2)
cos (x/2)=(+/-)</span>√[(1+cos x)/2]
cos (x/2)=(+/-)√[(1+5/13)/2]
cos (x/2)=(+/-)√[(18/13)/2]
cos (x/2)=(+/-)√[36/13]
cos (x/2)=(+/-)6/√13-------> cos (x/2)=(+/-)6√13/13
the angle (x/2) belong to the II quadrant
so
cos (x/2)=-6√√13/13

the answer Part A) is
cos (x/2)=-6√√13/13

Part B) sin (2x)
sin (2x)=2*sin x* cos x------> 2*[-12/13]*[5/13]----> -120/169

the answer Part B) is
sin(2x)=-120/169
