Simple...

you have -4.16-(-2.3)

but remember there's a negative in front of the (-2.3) so that gets switched into +2.3....

so now you'd have...

-4.16+2.3

=-1.86

Thus, your answer, B.

F(x)=x^3-9x<br> What is the average rate of change of f over the interval (1,6]?
Rzqust [24]

Answer:

34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ 1, 6 ]

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8, thus

average rate of change = \frac{162-(-8)}{6-1} = \frac{170}{5} = 34

What are the approximate solutions of 4x2 + 3 = −12x to the nearest hundredth?
Gwar [14]
First 
4x^{2} + 12x + 3 = 0
determine if this equation were factorable, it's not for this one
so I use quadratic formula, try to search the formula online

x1 =  \frac{-12 +  \sqrt{(12)^{2} - 4*4*3} } {2*4} =  \frac{-12 +  4\sqrt{6} }{8} =  \frac{4(-3 +  \sqrt{6}) }{8} =   \frac{-3 + \sqrt{6}}{2} = - 0.28
x2 = \frac{-12 - \sqrt{(12)^{2} - 4*4*3} } {2*4} = \frac{-12 - 4\sqrt{6} }{8} = \frac{4(-3 - \sqrt{6}) }{8} = \frac{-3 - \sqrt{6}}{2} = - 2.72

<span>x ≈ −2.72 and x ≈ −0.28 is the solution</span>
