Answer:

The value of c that completes the square  [tex]x^2+2x+c[/tex] is 1

Step-by-step explanation:

We need to find the value of c that completes the square  [tex]x^2+2x+c[/tex]

The formula used will be: [tex]a^2+2ab+b^2=(a+b)^2[/tex]

In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,

2(x)(1) = 2x

so, c= 1

Solving:

[tex]x^2+2x+c\\=x^2+2(x)(1)+(1)^2-(1)^2\\=(x+1)^2-1[/tex]

So, the value of c that completes the square  [tex]x^2+2x+c[/tex] is 1

Answer:

  The domain is always discrete when it is found from a table.

Step-by-step explanation:

A table necessarily lists a finite number of discrete points. The domain, as found from a table, is always discrete.

__

If the table is said to be a representation of a continuous function, then the domain of that continuous function will be continuous.

Your question seems to have to do with a table alone, not a table and an equation, or a table and a graph. A table (of points) alone cannot express a continuous domain.

__

Additional comments

One can conceive of tables that would have continuous domains, as, for example, a table with entries ...

  (x, y) = (0 ≤ x < 3, 3x+2), (3 ≤ x < 6, 4x-1), ...

Such a table is not a list of points, but is a piecewise function definition. We presume this is not what you're concerned with.

Answer:

Step-by-step explanation:

At home depot

Price of Christmas tree = $149.00

Discount = 15%

Amount discounted = 15% of $149

Amount discounted = 15/100 * $149

Amount discounted = 15 * 1.49

Amount discounted = $22.35

Amount she paid = $149-$22.35

Amount she paid = $126.65

At Lowe's:

Price of Christmas tree = $175.00

Discount = 260%

Amount discounted = 20% of $175

Amount discounted = 20/100 * $175

Amount discounted = 0.2 * 175

Amount discounted = $35

Amount she paid = $175-$35

Amount she paid at Lowe's = $140

From the prices above, it can be seen that Home Depot has a better deal since the price after removing discount is lower than that of Lowe's.

Amount she will save will be $140 - $126.65 = $13.35

Answer:

6/36

Step-by-step explanation:

1/36 + 5/36 = 6/36 OR 1/6

Answer:

1/5 of the farmers land has potatoes and pea plants growing on it

Step-by-step explanation:

so we are trying to figure out how much of the land is covered in potatoes and pea plants together so we add their fractions together

1/36 + 5/36 = 6/36

we then simplify the fraction by dividing both numbers by 6 since 6 can go equally within the fraction:

6/36 divided by 6  = 1/5

so 1/5 of his land is covered by potatoes and pea plants

Multiply

500x0.30=150

150 Is 30% Of 500

Answer:

Step-by-step explanation:

Step one:

given data

needed amount= $80

the amount already saved= $8

earnings per hour= $9

let the number of hours worked be n

and let y represent the total

the situation represented linearly is

y=mn+c

Step two:

substituting our data to find n

9n+8>80

9n>80-8

9n>72

divide both sides by 9

n>72/9

n>8

Therefore he must work a minimum of  8houees

Answer:

Pat Pet's Palace

Step-by-step explanation:

Price of dog food at Pat Pet's Palace = $3 per pound

Price of dog food at Mark's Mutt Market can be estimated using the graph given.

The graph is a proportional graph, thus, the constant of proportionality between cost and pound = y/x

Using the coordinates of a point on the line, (2.5, 10), constant of proportionality or unit rate = y/x = 10/2.5 = 4.

This means the price of dog food at Mark's Mutt Market is $4 per pound.

Therefore, Milo would pay a lower price per pound for dog food at Pat Pet's Palace.

Answer:

4 / 15

Step-by-step explanation:

Of all students ; 5/9 have a pets

Of the 5/9 who have a pet; 12 /25 have a dog

Fraction of the student in the school who have a dog;

12 /25 of fraction with pet

= 12 /25 of 5 /9

= 12 /25 * 5 / 9

= (12 * 5) / (25 * 9)

= 60 / 225

= 4 / 15

Answer:

Step-by-step explanation:  V= Voltage

                                               I= Current

                                               R= Resistance

Ohm's Law Mathematically expressed as: I= V/R or V= IR or R= V/I

V= 500

I= ?

R= 250

I= V/R

I= 500/250

I= 2 amps

Step-by-step explanation:

Answer:

The probability that the next customer will pay with credit card is approximately 0.33

Step-by-step explanation:

The given parameters are;

The number of customers that paid cash = 80 customers

The number of customers that used a debit card = 7 customers

The number of customers that used a credit card = 42 customers

The total number of different payments made = 80 + 7 + 42 = 129 payment

Probability = The number of desired outcome/(The number of possible outcome)

The probability that the next customer will pay with credit card = (The number of customers that used a credit card)/(The total number of different payments made)

∴ The probability that the next customer will pay with credit card = 42/129 ≈ 0.33 to the nearest hundredth.

Answer: 1.15

Step-by-step explanation:

Answer:

1.15 is the answer

Step-by-step explanation:

Answer:

Using exterior angle theorem, we can find the answer.

x+45+3x = 6x+5

4x+45 = 6x+5

45 = 2x+5

40 = 2x

x = 20

TO FIND <ABC, WE WILL NEED TO FIRST FIND THE EXTERIOR ANGLE.

6x+5

= 6(20)+5

= 120+5

= 125

The correct answer for me was true

Step-by-step explanation:

Answer:

Part A: m+1.37=7.9

Part B: 6.53 miles are left to be repaired.

Step-by-step explanation:

Given,

Length of repaired part = 1.37 miles

Total length to be repaired = 7.9 miles

Miles left to be repaired = m

Part A:

Create an equation to show the relationship between the number of miles repaired and the number of miles left to be repaired, m.

Miles left to be repaired + Length of repaired part = Total length to be repaired

m+1.37=7.9

Part B

How many miles are left to be repaired?

Subtracting 1.37 from both sides

6.53 miles are left to be repaired.

Keywords: length, subtraction

Answer:

(11,-2)

Step-by-step explanation:

11+5 /2=  8

6+-2= -4/2=-2

Answer:

(11,-2)

Step-by-step explanation:

The one point you have is P(5,6)

The midpoint is (8,2)

The other point is (x,y)

(x + 5) /2 = 8

(x + 5) = 8*2

x + 5 = 16

x = 16-5

x = 11

===========

(y + 6)/2 = 2

y + 6 = 2*2

y + 6 = 4

y = 4 - 6

y = - 2

Answer:

51t^3

Step-by-step explanation:

64+3=67

67 +(-16)=51

t^2 +t= t^3

now you just add them up but they cant be combined because one is a number and the other a variable w an exponent so we just get 51t^3
