What is equivalent to -6 to the -5 power?

Anarel [89]

Answer:

$-\frac{1}{7776}$

Step-by-step explanation:

Put negative exponents in the denominator to make them positive.

$\frac{1}{-6^5}$

$\frac{1}{-6*-6*-6*-6*-6}$

$\frac{1}{-7776}$

$-\frac{1}{7776}$

identify the initial amount,a,and the growth factor,b,in each exponential function.Break b into (1+r)where r is the rate of grow

Alla [95]

Given function : $y=1.05(1.46)^x$

We need to identify a " initial amount", b "growth factor", r " rate of growth".

We know, exponential growth formula

$y=a(b)^x$ , where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.

$y=1.05(1.46)^x$ ⇔ $y=a(b)^x$ .

We can see a= 1.05 and b = 1.46.

Now, b=1+r.

Therefore, 1+r =1.46.

Subtracting 1 from both sides, we get

1+r-1 =1.46-1

r = 0.46.

On converting 0.46 into percentage, we get

0.46 × 100 = 46.

Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.

I need to find the surface area of this

solmaris [256]

We need to find surface area, so we can imagine breaking it up into face net.

There will be 18 × 18 square base, four 18 × 40 rectangles, and four triangles with base 18 and height 13.

So the surface area would be sum of these areas.

That would be 18×18 + 4( 18 × 40 ) + 4( (1/2) 18×13 ) = <span>3672

Final answer: 3672 m</span>²

Hope this helps.

A student says that if the hypothesis is false, an argument cannot be valid. How do you respond ?

Anton [14]

If a student tells me that an argument that has a false hypothesis cannot be valid, I would reply that we need to look carefully at the meaning of validity in the context of logic. In everyday speech, we tend to use “valid” to mean the same thing as “true” or “accurate.” In logic, this is not the way the term is used.
