Answer:

question 7: irrational.

Question 8: rational.

Step-by-step explanation:

Complete question is;

Select all polynomial expressions that are equivalent to 6x⁴ + 4x³ – 7x² + 5x + 8.

A. 16x^(10)

B. 6x^(5) + 4x⁴ – 7x³ + 5x² + 8x

C. 6x⁴ + 4x³ - 7x² + 5x + 8

D. 8 + 5x + 7x² - 4x³ + 6x⁴

E. 8 + 5x – 7x² + 4x³ + 6x⁴

Answer:

Options C & E

C. 6x⁴ + 4x³ - 7x² + 5x + 8

E. 8 + 5x – 7x² + 4x³ + 6x⁴

Step-by-step explanation:

To find the polynomial expressions that are equivalent to 6x⁴ + 4x³ – 7x² + 5x + 8 simply means that both polynomials must have identical signs, identical number of terms and identical terms.

Now, by inspection of tall the options, we can see that options C & E are equivalent to the initially given polynomial.

For option C: 6x⁴ + 4x³ - 7x² + 5x + 8

This expression is the exact same thing as what was given in the question.

For option E: 8 + 5x – 7x² + 4x³ + 6x⁴

Rearranging this gives;

6x⁴ + 4x³ - 7x² + 5x + 8

Again this is exactly the same expression given to us in the question.

The sum of 5157 + 519 will be greater because she knows that 519 > 364.

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.

In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

Let's say two sum

x + y and x + z

If we want to calculate which is bigger then we need to look to y and z since x is common in both.

If y > z then x + y will be bigger and if z > y then x + z will be bigger.

Given the sum,

8157 + 364 and 8157 + 519

Now since 519 > 364 so (8157 + 519 ) > (8157 + 364)

Hence "The sum of 5157 + 519 will be greater because she knows that 519 > 364".

The given question doesn't have a numeric value, The numeric values are

8157 + 364 and 8157 + 519

Answer:

-7x+15y+2x-6y

-5x+9y

Step-by-step explanation:

Answer:

-7x - ( -15y ) - ( - 2x) + ( -6y )

=> -7x + 15y + 2x - 6y

=> ( -7x + 2x ) + (15y - 6y)

=> -5x + 9y

Hey! The answer is (-5,-3)!!

Step-by-step explanation:

Answer:

This is easy just like the other one you posted before

b+53+245=360

b+298=360

b=360-298

b=62

Answer:

62

Step-by-step explanation:

360 degrees is the total … You get the point.

360 degrees - 245 degrees

= 115 degrees

Now, we go onto the angle

The total measure of the angle is 115 degrees

The angle has been split into two angles. On of the angles measure is 53 degrees. To find the measure of the other angle, you have to subtract the measure of the angle that was given 53 degrees) by the total measure (115 degrees):

115 degrees - 53 degrees

= 62 degrees

Hope this helped you!

Answer:

The answer is below

Step-by-step explanation:

Let t represent the time in hour and A(t) represent the amount of accumulating rainfall at time t.

In the first three hours the rain fell at a constant rate of 25mm per

hour, hence:

A(t) = 25t     0 ≤ t ≤ 3

The rain then slows down and remains constant at 75 mm [i.e. 25(3)] for an hour.

The rain increases at a rate of 20t from 4 ≤ t ≤ 6. Hence the piecewise equation is given as:

[tex]A(t)=\left \{ {{25t\ \ \ \ \ \ \ \ \ \ for\ 0\leq\ t\ \leq\ 3} \atop {75\ \ \ \ \ \ \ \ \ \ for\ 0\leq\ t\ \leq\ 6 \atop {75+20(t-4)\ \ for\ 4\ \leq\ t\ \leq\ 6}} } \right. \\\\\left[/tex]

The fraction that is equal to 6 can be some of the following:

[tex]\mathbf{\dfrac{6}{1} \ ; \dfrac{12}{2} \ ; \dfrac{18}{3} \ ; \ \dfrac{24}{4}\ ; \ \dfrac{36}{6} }[/tex]

A fraction usually comprises a numerator and a denominator separated by a division line.

The factors of a given number are the numbers that can be divided in such a given number without a remainder.

From the given example, we are to determine the factors of 6, so we will think about a number that can be divided by 6 without leaving any remainder.

These numbers are:

From these numbers, we can pick two factors that when divided together, we get 6 as our result and without any remainder.

i.e.

The fraction that is equal to 6 are:

[tex]\mathbf{\dfrac{6}{1} \ ; \dfrac{12}{2} \ ; \dfrac{18}{3} \ ; \ \dfrac{24}{4}\ ; \ \dfrac{36}{6} }[/tex]

Answer:

A)196J

B)-208J

C)3467J

Step-by-step explanation:

We are given that a 20 kg cylindrical  mass is dropped onto the mat from a height of 1 m above the mat. During the impact,  the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to  only 4 cm thick.

So, The Mat gets compressed by : 10cm - 4 cm = 6 cm=0.06 m

a)

Using Conservations of energy

Potential energy at the top = Kinetic energy at the point before touching the surface

Kinetic energy = mgh= [tex]20 \times 9.8 \times 1 = 196 J[/tex]

b)

Work done  by the mat do to stop the fall of the cylinder =[tex]-mg(h+0.06)=-20 \times 9.8(1+0.06)=-208 J[/tex]

C)

Work done=[tex]\text{Average force} \times \text{ Compression of mat}[/tex]

[tex]208=F \times 0.06[/tex]

F=3467J

The distance between the two cities Dallas and Houston is 240 miles

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Given that:

1 inch = 50 miles

Hence:

4.8 inches = 4.8 inch * 50 miles per inch = 240 miles

The distance between the two cities Dallas and Houston is 240 miles

Odds in favor(Fiction book) = 6 / 13

Step-by-step explanation:

Given:

Number of fiction books = 12

Number of non-fiction books = 14

Find:

Odds in favor(Fiction book)

Computation:

Odds in favor(Fiction book) = Number of fiction books / Total books

Odds in favor(Fiction book) = 12 / (12+14)

Odds in favor(Fiction book) = 12 / 26

Odds in favor(Fiction book) = 6 / 13

Answer:

C. 35

Step-by-step explanation:

I just went through all the numbers, multiplied them by 2, because you start with x which is 50, and the goal is to get to 120 with 50 and a number multiplied by two, so I tried 35 which would be 70 when multiplied by two, then added 50, which would make 120.
