The number 16 must be added to the equation for making it a perfect square.

We must have the idea of algebraic identities to solve this problem. The identity of the sum of square of two variables is given below.

We know that [tex](a+b)^{2}= a^{2} +2ab+b^{2}[/tex].

So make a perfect square the equation must be of the form of [tex]a^{2} +2ab+b^{2}[/tex]

Given, [tex]x^{2} +8x=4[/tex]

     ⇒ [tex]x^{2} +2*4*x+ 4^{2}=4+4^{2}[/tex]

     ⇒  [tex](x+4)^{2}=20[/tex]

So, to complete the square we have added 16 to both the sides of the equation and now it is in the form of [tex](a+b)^{2}[/tex].

The required number to be added is 16.

Step-by-step explanation:

Cuz if 15 bears are made in 10 min you multiply by 60 cuz 60 min = 1 hour, so 15 times 60=900 then if the work 8 hr a day then u multiply 900 by 8 to get 7200 bears

Answer: rise is 4 and run is 5

Step-by-step explanation:

Answer:

down below

Step-by-step explanation:

To find the rise over run, you need to pick a point that intersects one of the axises. Then, you need to find a point that intersects the other axis. Third, you find the first point and begin moving up or down until you reach the height of the other point. From there, you count along that height line until you reach the second point. The number from counting on the y axis is the rise and the number from counting on the x axis is the run. So, you take the rise and put it over the run.

The reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and 0.80 is 0.99. The answer is option b.

The probability that a specific object will carry out its intended function for a specific amount of time under a specific set of circumstances without experiencing any failures is known as reliability.

The reliability definition is based on four criteria: function, fulfillment likelihood, duration, and environment. Maintainability and reliability are related because when a machine or product malfunctions, there may be a way to get it back into working order.

When we use the phrase "talking reliability-smart," we mean that any of the aspects that shape the device in parallel can be considered. This does not necessarily imply that they are physically parallel (in all circumstances), as parallel capacitors have a certain behavior in the circuit and may malfunction if one of them fails.

Parallel forms reliability is a measure of reliability obtained by giving the same set of people different versions of an assessment tool (each version must contain items that probe the same construct, talent, knowledge base, etc.

The complete question is given below:-

What is the reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and 0.80?

a. 0.875

b. 0.99

Step-by-step explanation:

Answer:

84%

Step-by-step explanation:

In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...

19oz + 9oz + 7oz = 35oz

Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.

35oz / 19oz = 1.84

1.84 - 1 = 0.84

0.84 * 100 = 84%

Finally, we can see that the puppy had an 84% increase since the first visit.

Answer:

It's the y value of the point where the line intersects the y- axis.

The quantity is 25/8.

Given in words to evaluate the expression, 2 squared times 2 to the power of negative 5 and over 5 to the power of negative two.

Square of a number denotes a number to the power of 2.

The expression is :   [tex]\frac{2^2\times2^{-5}}{5^{-2}}[/tex]

We have to use the law of exponents here:

   [tex]a^m \times a^n = a^{m+n}[/tex]

and

  [tex]\frac{a^m}{a^n} = a^{m-n}[/tex]

In the above cases, the bases should be same for the two numbers.

So   [tex]2^2 \times 2^{-5} = 2^{-3}[/tex]

Also, negative exponents like  [tex]a^{-m} = \frac{1}{a^m}[/tex].

Therefore,     [tex]\frac{2^{-3}}{5^{-2}} = \frac{5^2}{2^3} =\bold{ \frac{25}{8} }[/tex]

Answer: -13w - 7

Step-by-step explanation:

-6w + (-8) + 1 + (-7w)

Combine the like terms

-8 + 1 = -7

-6w + (-7) + (-7w)

-6w + (-7w) = -13w

-13w + (-7)

However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7
