The polynomial is subtracted using the distributive property.
.. (16k^3 -3v^4) -(-9k^3 +6v^4)
.. = 16k^3 -3v^4 +9k^3 -6v^4
.. = (16 +9)k^3 +(-3 -6)v^4
.. = 25k^3 -9v^4

"Invert" means different things in different contexts. Here we suppose it means you simply want the reciprocal of this difference:

$\frac{1}{25k^{3} -9v^{4}}$

If h(x) = f<img src="https://tex.z-dn.net/?f=h%28x%29%20%3D%20f" id="TexFormula1" title="h(x) = f" alt="h(x) = f" align="absmidd

Answer:

g(x) = x+1

Step-by-step explanation:

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

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

h(x)= (fog)(x)= f(g(x))= $\sqrt[3]{g(x)+2}$

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

cubing both sides ,we get

x+3 = g(x) +2

solving for g(x) ,we get

g(x) = x+1

15 points if you answer the question

The mnemonic SOH CAH TOA helps you remember that

... Sin = Opposite/Hypotenuse

The side opposite angle K is marked with length 5. The hypotenuse KM is marked with length 10. Using the above relationship ...

... sin(∠K) = 5/10 = 1/2

The first choice is appropriate: $\dfrac{1}{2}$

Two faulty machines, M1 and M2, are repeatedly run synchronously in parallel (i.e., both machines execute one run, then both exe

leonid [27]

The event that either M1 or M2 fails has probability

$P(M_1\text{ fails or }M_2\text{ fails})=P(M_1\text{ fails})+P(M_2\text{ fails})-P(M_1\text{ and }M_2\text{ both fail})$

by the addition rule. Failure events are independent, so

$P(M_1\text{ and }M_2\text{ both fail})=P(M_1\text{ fails})P(M_2\text{ fails})$

so that

$P(M_1\text{ fails or }M_2\text{ fails})=p_1+p_2-p_1p_2$

Denote this probability by $p$ . Then $X$ follows a geometric distribution with this parameter $p$ and has density

$P(X=x)=\begin{cases}(1-p)^{x-1}p&\text{for }x\ge1\\0&\text{otherwise}\end{cases}$

The expectation is $\dfrac1p=\dfrac1{p_1+p_2-p_1p_2}$ .

Is it congruent SSS or Congruent ASA

Novosadov [1.4K]

It wouldn’t be SSS cause not all of the sides are the same so congruent asa?
