your answer is: -4p - 2

Explanation:

first, ignore the -4p for now. do the small equation without the variable. SO, we would do <em>7 - 5 = 2. </em>

there aren't any addition symbols being used in the equation and there aren't any other numbers with the p variable. this means that the -4p will stay the same. so we would end up with -4p - 2

<em>(this isn't the normal way of solving this, but I did my own way and got the same answer)</em>

There is one error in one of five blocks of a program. To find the error, we test three randomly selected blocks. Let X be the n
marusya05 [52]
Probability(error in one block)= 1/5
<span>Probability(error in 3 blocks)= 3*(1/5)= 0.6</span>

Let, 
     0 = No error
<span>     1 = error
</span>Hence.
E(x) = 0.4 x 0 x+0.6 + 1 
        = 1.6

Cosθ = adjacent / hypotenuse

\cos(47)  =  \frac{28}{x}  \\ 0.68 =  \frac{28}{x}  \\ x =  \frac{28}{0.68}  \\ x = 41.1 \\ x = 41

I hope I helped you^_^

If h(x)=(fog)(x) and h(x)=³√x+3, find g(x) if f(x) =³√x+2
ipn [44]

Answer:

g(x)=x+1

The problem:

Find g(x) if h(x)=(f \circ g)(x),

h(x)=\sqrt[3]{x+3}, and

f(x)=\sqrt[3]{x+2}.

Step-by-step explanation:

h(x)=(f \circ g)(x)

h(x)=f(g(x))

Replace x in f(x)=\sqrt[3]{x+2} with g(x) since we are asked to find f(g(x)):

\sqrt[3]{x+3}=\sqrt[3]{g(x)+2}

\sqrt[3]{x+1+2}=\sqrt[3]{g(x)+2}

This implies that x+1=g(x)

Let's check:

(f \circ g)(x)

f(g(x))

f(x+1)

\sqrt[3]{(x+1)+2}

\sqrt[3]{x+1+2}

\sqrt[3]{x+3}  which is the required result for h(x).
