Answer:

Step-by-step explanation:

They all give 8r so that is not the distinguishing characteristic.

The first one in column A gives

12r + t - 4r + 6t

12r - 4r + t + 6t

8r + 7t  

This is the third one in column B

2nd one in Column A

12r + 2t - (4r + 10t)               Remove the brackets

12r + 2t - 4r - 10t                  Pay close attention to 10t becoming -10t. The minus sign effects both terms inside the brackets.

12t - 4t + 2t - 10t                  Combine

8r - 8t                                   Now take out the common factor (8)

8(r - t)                                    That's the top one in column B

3rd one in column A

12(r + t) - 6(r +t) + 4(r + t) - 2(r+t)    They all have r+t so r + t is a common factor)

(r+t) [12 - 6 + 4 - 2]                          Combine

(r + t ) [ 8 ]

This is the second one in  column B

The trick here is to look out for common factors. Don't remove the brackets. But it takes a bit of practice before you know that

Answer:

A Trinomial expression has 3 terms.

If it has degree 2, then the exponent of the leading term will be 2.

If the leading coefficient is -5, then the leading term will be [tex]-5x^2[/tex]

Written in standard form:  [tex]y=-5x^2+bx+c[/tex]

We are not given any information about the coefficients of the remaining two terms, so we can substitute any values for these:

Therefore, [tex]y=-5x^2+3x+2[/tex]

Note the standard form

Here we have

So

the expression is

The system of equations that model this situation are [tex]h = -16t^{2}+15t +6[/tex] and [tex]h = 3t +10[/tex].

As we know,

Projectile motion formula,

[tex]h = -16t^{2}+vt +h_{0}[/tex].....(1)

Where, t = time since the measuring tape was thrown.

h = height in feet above the ground.

Projectile motion is a form of motion experienced by an object or particle that is projected near the Earth's surface and moves along a curved path under the action of gravity only.

It is given that:

v =15 feet/sec

h₀ = 6 feet

So, (1) will become,

[tex]h = -16t^{2}+15t +6[/tex]

Also, h = distance of worker's arm from the ground + speed of bucket * time(t)

[tex]h = 3t +10[/tex]

Therefore, the system of equations that model this situation are [tex]h = -16t^{2}+15t +6[/tex] and [tex]h = 3t +10[/tex].

Step-by-step explanation:

Proof:

Answer:

-x^3 + x^2 - 2x - 4

Step-by-step explanation:

You have to subtract

Let o = the polynomial

So you know 2x^3 - x^2 + 4x + 5 - o = x^3 + 2x - 9

Now you do 2x^3 - x^3 = x^3

then you -x^2 + answer = 0

you need to cancel it out

to cancel, you found out that it is x^2

Now you need to make from 4x to 2x.

To do that, you do 4x - 2x and you get 2x

Lastly you need to change -5 to 9. To do that you add -4.

Now since it is subtraction you have to distribute

2x^3 - x^2 + 4x - 5 -(x^3 - x^2 + 2x + 4)

= 2x^3 - x^2 + 4x + 5 - x^3 + x^2 -2x -4

= x^3 -2x + 9

Answer:

Step-by-step explanation:

The number closest to 0 is the number whose absolute difference from 0 is the smallest

0.5 is the closest number to 0

The numbers are given as:

–4, 3, 0. 5, 1

Calculate their absolute difference with 0

|-4 - 0| = 4

|3 - 0| = 3

|0.5 - 0| = 0.5

|1 - 0| = 1

The smallest absolute difference is 0.5

Hence, 0.5 is the closest number to 0

Gross domestic product is the economic indicator to measure of all goods and services produced within a given economy in one year

An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance.

We need to find the which economic indicator is the measure of all goods and services produced within a given economy in one year.

A trade deficit occurs when a country imports more than it exports

A trade surplus is an economic measure of a positive balance of trade, where a country's exports exceed its imports.

GDP measures the monetary value of final goods and services—that is, those that are bought by the final user—produced in a country in a given period of time

Hence, gross domestic product is the economic indicator to measure of all goods and services produced within a given economy in one year

The polynomial that is prime is given by Option C: [tex]10x^2 - 4x +3x +6[/tex]

Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.

(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)

Checking all the listed polynomials for them being prime or not:

Rewriting it as:

[tex]x^3+3x^2+2x+6 = x^2(x+3) + 2(x+3) = (x^2 + 2)(x+3)[/tex]

shows that this polynomial has factors. Thus, it isn't prime polynomial

Rewriting it as:

[tex]x^3 + 3x^2 -2x -6 = x^2(x+3) -2(x+3) = (x^2-2)(x+3)[/tex]

shows that this polynomial has factors. Thus, it isn't prime polynomial

We can rewrite it as:

[tex]10x^2 -4x + 3x -6 = 10x^2 -x -6 = f(x) \: \rm (say)[/tex]

This polynomial is prime polynomial as it is irreducible in terms of polynomials having their coefficients as integers.

Case 4: [tex]10x^2 -10x + 6x - 6[/tex]

It can be factored as:

[tex]10x(x-1) + 6(x-1) = (x-1)(10x-6)[/tex]

This is not a prime polynomial.

A city starts with a population of 500,000 people in 2007. Its population declines according to the equation

P(t) = 500,000e -0.099t

where P is the population in t years later. Approximately when will the population be half the initial amount?

Answer:

2014

Step-by-step explanation:

Given the exponential growth function :

P(t) = 500,000e^-0.099t

Where P is population in t years later

When the population will 1/2 the initial amount

1/2 the initial amount = 1/2 * 500,000 = 250,000

P(t) = 250,000

250,000 = 500000e^-0.099t

250,000/500000 = e^-0.099t

In(0.5) = - 0.099t

t = −0.69314 / - 0.099

t = 7.0014

t = 7

Year which population = 500,000 = 2007

Hence, half the population will be attained on (2007 + 7) = 2014

After 7 years population of the city will be half of the initial amount.

Population function:

[tex]P(t) = 500000 e^{-0.099t}[/tex]

Initial population means population at t=0

P(0) = 500000

Half of initial population = 250000

So, we need to calculate the time t when the population will be half of the initial amount.

[tex]250000= 500000 e^{-0.099t}\\\\e^{-0.099t} = \frac{1}{2}[/tex]

Taking log both sides

-0.099t (log e)= log (1/2)

The logarithm of e is 1 when considering the base of the log as e.

So, -0.099 t= -0.693

t=7

Therefore, After 7 years population of the city will be half of the initial amount.

Step-by-step explanation:

If we convert the percentages to decimals (120% = 1.2 & 80% = 0.8), we can use this equation to find B:  1.2A = 0.8b

Since we know a, we then have 1.2 * 12 = 0.8b

Solving for B gives us b = 18
