Answer:

a. -1, odd; 2, even

b. [tex](x+1)(x-2)^2[/tex]

c. odd likely 3

Step-by-step explanation:

A polynomial graph has several features we look for to determine the equations.

The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity. Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial. The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.

In this graph, there are two real zeros: -1,2

We can write them in intercept or factored form as (x+1) and (x-2).  

Because the graph crosses the x-axis at -1, it's multiplicity is odd likely 1. However, the graph does not cross at 2 and has an even multiplicity likely 2.

The graph is ends up and is a sideways s so is positive with an odd degree.

This means the function has a degree of 3 or higher with the degree being odd.

You have 10 batteries sitting on your desk, three of which are dead. You choose 2 batteries are random for you calculator. What is the expected number of good batteries that you get?

A) 0

B) 1

C) 1.4

D) 2

Answers

Answer:

C) 1.4

Step-by-step explanation:

The probability of choosing 2 good ones is 7/10·6/9 = 42/90.

The probability of choosing 1 good one is 7/10·3/9 +3/10·7/9 = 42/90.

The probability of choosing 0 good ones is 3/10·2/9 = 6/90

The expected value is the sum of the product of number of good ones and their probability:

... 2·42/90 +1·42/90 +0·6/90 = (2+1)·42/90 = 42/30 = 1.4

Step-by-step explanation:

1. A fraction exponent can be represented using a radical. The base number is the number in the radical. The numerator of the fraction is the exponent inside the radical. The denominator is the type of radical.

A total of 17,100 seats are still available for the next hockey game. If 62% of the tickets are sold, how many seats are in the arena? A. 7,100 seats B. 7,900 seats C. 45,000 seats D. 27,900 seats

Answers

Answer:

We have

seats x ( 62 / 100 ) = (seats - 17,100);

seats x 62 = 100 x (seats - 17,100);

seats x 62 = seats x 100 - 1710000;

1,710,000 = seats x 38;

seats = 1,710,000 ÷ 38;

line A and line B are parallel. If line A is 2x + 3y =10, what is the equation for line B if it passes through the point (-6,8)

Answers

Let us Represent the Line A in the Standard form : y = mx + c

where : m is the Slope of the Line and c is the y-intercept

Given : Equation of Line A is 2x + 3y = 10

[tex]\bf{\implies y = \frac{-2}{3}x + \frac{10}{3}}[/tex]

Comparing with the Standard form, We can notice that :

Slope of Line A [tex]\bf{= \frac{-2}{3}}[/tex]

We know that : Parallel lines have Same Slope

Given : Line A and Line B are Parallel

⇒ Slope of Line B [tex]\bf{= \frac{-2}{3}}[/tex]

Given : Line B passes through the Point (-6 , 8)

We know that : Equation of a Line passing through a Point (x₀ , y₀) and having Slope 'm' is given by : y - y₀ = m(x - x₀)

Here : x₀ = -6 and y₀ = 8 and Slope(m) [tex]\bf{= \frac{-2}{3}}[/tex]

Equation of Line B is :

[tex]\bf{\implies y - 8 = \frac{-2}{3}(x + 6)}[/tex]

⇒ 3y - 24 = -2x - 12

⇒ 2x + 3y = 12

What is the vertex and axis of symmetry for y=4x^2-12x+9?

Answers

Answer:

axis of symmetry   x=3/2

vertex  (3/2, 0)

Step-by-step explanation:

to find the axis of symmetry we use h = -b/2a

where ax^2 + bx+c


h = -(-12)/2(4)

h= 12/8

h = 3/2

the axis of symmetry is x = 3/2

the x coordinate of the vertex is h x=3/2

to find k, the y coordinate of the vertex, substitute x=3/2 into the equation

y=4x^2-12x+9

y=4(3/2) ^2-12(3/2)+9

 = 4 (9/4)  - 6*3 +9

Which is equivalent to 80 1/4 ?

Answers

Hey there!

"Which is equivalent to [tex]80\frac{1}{4}[/tex]?"

In order for you to solve this particular equation, you multiply the front number from the denominator, then whatever that outcome is, add to the nominator

So,  

[tex]80\frac{1}{4}[/tex]

[tex]80(4) = 320[/tex]

[tex]320 +1 = 321[/tex]

[tex]4[/tex] stays the same

[tex]\boxed{Answer: \frac{321}{4}}[/tex]

If you want the decimal form, simplify the  the mixed  to a improper then you should get a outcome of: [tex]80.25[/tex]

For percentage do the fraction out of [tex]100[/tex] then solve it from there ([tex]0.8025[/tex]) would be the percentage form

Good luck on your assignment and enjoy your day!

~[tex]LoveYourselfFirst:)[/tex]

[tex]80\frac{1}{4}[/tex] is equivalent to the decimal number 80.25, which can also be expressed as the improper fraction 321/4.

The question asks for an equivalent of the number [tex]80\frac{1}{4}[/tex].  To find this, we can convert the mixed number to an improper fraction or decimal. Since 1/4 is a standard fraction that is equivalent to 25 percent, we can express 1/4 as 0.25. Adding this to 80, we get an equivalent decimal number of 80.25. Another way to express 80 1/4 would be as an improper fraction, which would be [tex]\frac{321}{4}[/tex] because 80 times 4 equals 320, plus the numerator 1 equals 321.

The graph is translated three units down.

The graph is translated three units up.

Answers

Answer:

The graph is translated three units down.

Step-by-step explanation:

We know that, a 'Translation' is an transformation where the figure or graph is shifted in any direction.

According to our question (x,y) becomes (x, y-3) , this means that the graph value of 'x' co-ordinate remains same and the value of 'y' co-ordinate is decreased by 3 units.

So, the graph is shifted three units downwards i.e. it is translated three units down.

Answers

Answer:

(–6, –4)

Step-by-step explanation:

After converting the two equations from standard form to slope -int form I graphed the two equations on a coordinate plane and found the intersection (in this case solution) of the equation to be (–6, –4)

Answer:

(–6, –4)

Step-by-step explanation:

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.

It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation.

Using the substitution method, make y the subject in the first equation

y = 5x + 26

substitute into the second equation

2x -7(5x + 26) = 16

-33x - 182 = 16

-33x = 16 + 182

-33x = 198

x = 198/-33

x = -6

since y = 5x + 26

y = 5(-6) + 26

= -30 + 26

= -4

hence (x,y) = (-6,-4)

Substitute values for Speed and Distance

[tex]\mathbf{Time = \frac{3670000000\ miles}{1.17 \times 10^7 miles/mins}}[/tex]

[tex]\mathbf{Time = \frac{3670000000\ mins}{1.17 \times 10^7 }}[/tex]

Step-by-step explanation:

A triangle has 3 sides.  We add up all three sides to get the perimeter.

s1+s2+s3 = Perimeter

Combine like terms

11x+8 = Perimeter

Answer:

P = 11x + 8 cm

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of the three sides.

... P = s1 + s2 + s3

... P = (x +4 cm) +(3x +1 cm) +(7x +3 cm) . . . . substitute for s1, s2, s3

Gina opened a bank account with $40. She plans to add $20 per week to the account and not make any withdrawals. After how many weeks will Gina have exactly $700 in her account, excluding interest?

Answers

Answer:

After 33 weeks.

Step-by-step explanation:

Let w be number of weeks.

We have been given that Gina opened a bank account with $40. She plans to add $20 per week to the account and not make any withdrawals. So the balance after w weeks will be 20w+40.

To figure out number of weeks Gina will have exactly $700 in her account, we will equate the balance after w weeks to 700.

[tex]20w+40=700[/tex]

Let us subtract 40 from both sides of equation.

[tex]20w+40-40=700-40[/tex]

[tex]20w=660[/tex]

Upon Dividing both sides of our equation by 20 we will get,

[tex]\frac{20w}{20}=\frac{660}{20}[/tex]

[tex]w=\frac{660}{20}[/tex]

[tex]w=33[/tex]

Therefore, after 33 weeks Gina will have exactly $700 in her account, excluding interest.

We can use the formula for arithmetic sequences

an =a1+d(n-1)

where a1 is the first term in the sequence

d is the common difference

and n is the term number

a1 is -13

d is found by taking the second term and subtracting the first term

d = -6--13
