What number should be added to both sides of the equation to complete the sqaure x^2+8x=4
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.

A toy factory makes 15 teddy bears every 10 minutes. The factory makes teddy bears for 8 hours each work day. What is the fewest number of work days the factory will need to make 5,000 teddy bears? Write an explanation to show how you determined your answer.
Answer:
1 day
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

MATH Simplify the expression -6w + (-8) + 1 + (-7w)
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
Lola's puppy weighed 19 ounces on the second visit the puppy had gained 9 ounces on the third visit the puppy heaven gained another 7 ounces what is the percent increase since the first visit and the puppy weighed around to the nearest percent
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.
The points (-5, 5) and (5, r) lle on a line with slope -3. Find the missing coordinate r.
Answer:
r = -25
Step-by-step explanation:
slope is change in "y" over change in "x"
so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.
Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.
Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25
So the two points are (-5, 5) and (5, -25)

calcaulate the reliability of the system if all components function properly with probability 0.95. [hint: a,b and c,d are not in sequel. start with parallel components!]
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.
What is reliability?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

d. 0.76

What is the slope of the line that passes through the points (4, 6)and (-16, -18)? Write your answer in the simplest form.
Answer:
6 / 5
I hope it is correct.
Step-by-step explanation:
Slope is (y2 - y1) / (x2 - x1)
choose two points: (4, 6) and (-16, -18)
(-18 - 6) / (-16 - 4)
-24 / -20 (simplify by -4)
6 / 5
