What's the domain and range for (×+4)-1

1 answer:

7 0

$\bf a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad

\cfrac{1}{a^{ n}}\implies a^{-{ n}}\\
---------------\\
thus\\
(x+4)^{-1}\implies \cfrac{1}{x+4}
\\\\
$
$\bf if\qquad \cfrac{1}{0} \implies$ undefined

so.. what value of "x" makes x+4 to 0?

the domain will be, all real numbers, except that value

about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there

The leg of a right triangle is 2 units and the hypotenuse is 5 units. What is the length, in units, of the other leg of the tria

AVprozaik [17]

For this question, we have to use the Pythagorean theory since we're dealing with a right triangle.

a² + b² = c²

We're given the value of the hypotenuse and a leg, therefore we're looking for the value of the other leg.

Now let's plug in the given data into our equation.

2² + b² = 5²
4 + b² = 25
b² = 25 - 4
b² = 21
√b² = √21 = b

The correct answer is B) √21

Prove Forall a, b, c elementof Z^+, if a|(b + c) and a|c then a|b.

In-s [12.5K]

Answer with explanation:

If A is a positive Integer , then if A divides B , then in terms of equation it can be written as

→B=A m ,where m is any integer.

⇒Now, it is given that , three elements , a , b and c belong to set of Integers.

a divides b+c,and a divides c

then we have to prove that , a divides b.

Proof

→b+c= k a,where k is an integer , as b+c is divisible by a.

→Also, c= m a, where m is an integer.Because c is divisible by a.

→b+ m a= k a

→b=k a - ma

→b=a (k -m)

Since, k and m are both integers.So , k-m will be also an integer.

Let, k-m =p

→b=a p

which shows that , b is divisible by a.

Hence proved.

Answer:

The 2 Gallon Tank is Enough

Step-by-step explanation:

A drink bottler needs to bottle 16 one-pint bottles. He has a 2 gallon tank and a 3 gallon tank.

There are 8 pints in a gallon. This means that 2 gallons would be 16 pints.

$8 * 2 = 16$

So, the 2 gallon tank has 16 pints, which means that the 2 gallon tank should be enough to bottle all 16 bottles.

The amount of soda in a half-liter bottle follows a normal distribution. Assume μ = 500 ml and σ = 10 ml. A government auditor w

ira [324]

The probability that the company will be fined is 0.1587.

<h3>How to illustrate the probability?</h3>

From the information given, it was assumed that μ = 500 ml and σ = 10 ml.

Also, the random sample of 5 bottles has a sample mean under 490 ml.

Here, the probability will be:

= P(x < 490)

= P[(z < (490 - 500)/10]

= P (z < -10/10)

= P(z < -1)

Looking at this under the z table, the probability will be 0.1587

The probability is 0.1587.
