x^2 + 5x + 13 pls help

Answers

Answer 1

Answer:

Not factorable

Step-by-step explanation:

We are given a polynomial and are asked to solve or factor it I am assuming.

To solve this, there is a certain rule I like to follow, which is for b (in this case 5), you have to find two numbers that multiply to it, and for c (in this case 13), you have to find two numbers that add to it.

Since no two numbers multiply to 5 and add to 13, therefore this polynomial is not factorable.

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 38 minutes of calls is $ 25.06, and the remaining credit after 69 minutes of calls is $21.03. What is the remaining credit after 80 minutes of calls?

Answers

Answer: $19.6

Step-by-step explanation:

Linear function: f(x)=mx+c

, where  m= rate of change in f(x) with respect to x.

c = Initial value.

Let c = Initial value of card , m= Charge per minute

x= Number of minutes calling time.

Then, 25.06= 38m+c   (i)

21.03=69m+c (ii)

Eliminate (ii) from (i)

[tex]4.03=-31m\\\\\Rightarrow\ m=\dfrac{4.03}{-31}\\\\\Rightarrow\ m=-0.13[/tex]

Put m in (i) , we get

[tex]25.06= 38(-0.13)+c\\\\\Rightarrow\ 25.06=-4.94+c\\\\\Rightarrow\ c=25.06+4.94\\\\\Rightarrow\ c=30[/tex]

i.e. f(x)=-0.13x+30

if x=80 then

f(80)= -0.13(80)+30

=-10.4+30

=19.6

Hence, the remaining credit after 80 minutes of calls = $19.6

The average diameter of a tree is measured over time. The equation y = 3/4x, where x is time in years and y is the
diameter in inches, models this relationship.
What is the predicted diameter, in inches, of the tree after 12 years?

Answers

Answer:

The predicted diameter of a tree after 12 years is 9 inches.

Step-by-step explanation:

The average diameter of the tree is represented by [tex]y = \frac{3}{4}\cdot x[/tex]. The predicted diameter of the tree after 12 years is determined by evaluating the linear function at [tex]x = 12[/tex]. That is:

[tex]y = \frac{3}{4}\cdot (12)[/tex]

[tex]y = 9[/tex]

The predicted diameter of a tree after 12 years is 9 inches.

Each pair of polygons is similar. Find each missing side measure. two polygons 12 on top 5 on bottom second polygon 48 on top x on bottom

Answers

Answer:

[tex]x = 20[/tex]

Step-by-step explanation:

Given

First Polygon:

[tex]Top = 12[/tex]

[tex]Bottom =5[/tex]

Second Polygon

[tex]Top = 48[/tex]

[tex]Bottom =x[/tex]

Required

Find x

Since both polygons are similar, then:

[tex]Ratio = Top:Bottom[/tex]

For the first:

[tex]Ratio = 12:5[/tex]

For the second

[tex]Ratio = 48:x[/tex]

Equate both ratios

[tex]12:5 = 48:x[/tex]

Express as fraction

[tex]\frac{12}{5} = \frac{48}{x}[/tex]

Cross Multiply

[tex]12 * x = 48 * 5[/tex]

Solve for x

[tex]x = \frac{48 * 5}{12}[/tex]

[tex]x = \frac{240}{12}[/tex]

[tex]x = 20[/tex]

Step-by-step explanation:

We assume you want the solution to the system ...

2x−3y=3x=y+2

The second equation gives a nice expression for x, so we can use that in the first equation.

  2(y+2) -3y = 3 . . . . substitute for x in the first equation

  2y +4 -3y = 3 . . . . . eliminate parentheses

  -y = -1 . . . . . . . . . . . collect terms, subtract 4

  y = 1 . . . . . . . . . . . . multiply by -1

  x = 1 +2 = 3 . . . . . . substitute for y in the second equation

The solution is (x, y) = (3, 1).
