(x+7)(x² + 4x + 3)
(x+3)

Answers

Answer 1

The expression which can be rewritten as (x+7)(x - 1) as required in the task content is; Choice C; (x+3)²-16.

Identifying the equivalent expression.

It follows from the task content that the expression which can be rewritten as ( x + 7 ) ( x - 1 ) be determined.

By polynomial expansion, the expression (x+7)(x - 1) can be written as;

x² + 7x - x - 7

= x² + 6x - 7.

By observation, it follows that the expression which seems to have a degree of 2 is; (x + 3)² - 16.

On this note, by checking; we have;

x² + 6x + 9 - 16

= x² + 6x - 7

Ultimately, the expression which could be rewritten as (x+7)(x - 1) and is to be identified is; Choice C; (x + 3)² - 16.

Which equation would you use to solve this problem: Laura bought 4 1/3 bushels of apples for $16. How much did each bushel cost? *

Answers

Answer: $3.69

Step-by-step explanation:

Laura bought 4 1/3 bushels of apples.

Firs convert this to an improper fraction for easier calculation:

= 13/3 bushels of apples.

If cost $16 altogether, individually they must cost:

= Cost / Quantity purchased

= 16 ÷ 13/3

= 16 * 3/13

= $3.69

Note: You can divide by a fraction by multiplying the inverse of that fraction.

Answers

Answer:

[tex] \boxed{ \large{ \underline{\tt{Equal \: to \: each \: other}}}}[/tex]

Step-by-step explanation:

When two lines interesect , the angles formed opposite to each other are called vertically opposite angles. Vertically opposite angles [ V.O.A ] are always equal to each other.

Refer to the attachment! In the given figure , [tex] \angle[/tex] p and [tex] \angle[/tex] s are opposite to [tex] \angle[/tex]r and [tex] \angle[/tex]q respectively. Therefore [tex] \angle[/tex]p and [tex] \angle[/tex]r are vertical angles. Similarly , [tex] \angle[/tex]s and [tex] \angle[/tex]q are also vertical angles.

Hence , Our final answer : Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are equal to each other .

A certain population is initially 8,951 but declines by 8% every second. Find an exponential formula that gives the population as a function of time. What will be the population after half of a minute?

Answers

9514 1404 393

Answer:

  734

Step-by-step explanation:

The growth factor is 1 -8% = 0.92. This is the base of the exponential formula. The multiplier is the initial value, so you have ...

  p = 8951×0.92^t

When t=30, this evaluates to ...

  p = 8951×0.92^30 ≈ 733.68

The population after half a minute will be about 734.

Answers

Answer:

t = 3.11 seconds

Step-by-step explanation:

Given that,

At the circus, a clown is shot from a cannon. This situation can be modeled by the function :

[tex]h = -16t^2 + 45t + 15[/tex]

Where

'h' is height in feet and 't' is time in seconds

We need to find how long did it take for the clown to reach his highest point. It can be calculated as follows :

[tex]-16t^2 + 45t + 15=0[/tex]

We need to solve for t. It can be calculated as follows :

[tex]t=\dfrac{-45\pm \sqrt{45^2-4(-16)(15)} }{2(-16)}\\\\t=-0.301\ \text{and}\ 3.11\ s[/tex]

So, the required time is 3.11 seconds.

Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.
Define a variable that can be used to determine how many pens she bought.
Write an equation using the variable and solve to determine how many pens she bought.

Answers

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n  = 3.48

n = [tex]\frac{3.48}{0.29}[/tex]

  = 12

Therefore, Kamila bought 12 pens.

There are two right angle triangles, triangle ABC and Triangle EDF. Measure of angle ACB and angle EFD are 90. Side AB is congruent to side ED, Side AC is congruent to side DF. What theorem can be used to show that ABC ≅ DEF?

Answers

Answer:

SAS theorem

Step-by-step explanation:

Given

Triangles ABC and DEF

[tex]AB = ED[/tex]

[tex]AC = DF[/tex]

[tex]\angle ACB = \angle EFD = 90^{\circ}[/tex]

Required

Which theorem shows the similarity between both triangles

The following can be deduced from the given parameters.

[tex]AB = ED[/tex] ===> Equal Sides

[tex]AC = DF[/tex] ===> Equal Sides

[tex]\angle ACB = \angle EFD = 90^{\circ}[/tex] ===> Equal Angle

This implies that two sides and 1 angle of both triangles are equal.

Hence, the theorem to use is the SAS theorem.
