Please Can Someone Help? As I'm Not Confident This Is Right For Factorising 4b^2 + 8b + 3

Answers

Answer 1

Answer:

your answer is correct

Step-by-step explanation:

4b² + 8b + 3

Consider the factors of the product of the coefficient of the b² term and the constant term which sum to give the coefficient of the b- term.

product = 4 × 3 = 12 and sum = + 8

The factors are 2 and 6

Use these factors to split the b- term

4b² + 2b + 6b + 3 ( factor the first/second and third/fourth terms )

= 2b(2b + 1) + 3(2b + 1) ← factor out (2b + 1) from each term

= (2b + 1)(2b + 3)

Need help on #9 and #10 please ASAP. Was busy with a family emergency and missed my class on this.

Answers

Answer:

#9

given, angle BOD = 95 degree

and angle     COD = 35 degree

assume that, angle BOC = x degree

so, angle BOC + angle COD = angle BOD

or, x + 35 degree = 95 degree

so, x = 95 degree - 35 degree = 60 degree

so, angle BOC = 60 degree

#10

given, angle AOC = right angle = 90 degree

and angle    AOB = 30 degree

assume that, angle BOC = y degree

so, angle AOB + angle BOC = angle AOC

or, 30 degree + y = 90 degree

so, y = 90 degree - 30 degree = 60 degree

so, angle BOC = 60 degree

Thomas, a waiter at a local restaurant, is paid $ 4 an hour plus tips. His friend Marie works at a local bookstore for $12 an hour. Marie and Thomas worked the same number of hours. If Thomas made $120 in tips and both made the same amount of money, how many hours

Please just write the equation out.

Answers

Let h be the number of hours worked.
Let x be the tips
Let t be Thomas
Let m be Marie’s pay

t=4h+x

(plug in 120 for x)

t=4h+120
——————————————
m=12h

(They made same amount of money working the same amount of hours)

4h+120=12h
120=8h

How many hours did they both work? :)

Find the distance between the points (6,3) and (-1,-6).

Answers

Answer:

All you need is the distance formula.  The distance betwen two points

(x1,y1) and (x2,y2) is d= sqrt((x2-x1)2 + (y2-y1)2)

 

plugging in the values we get:

d= sqrt((6-(-6))2 + (6-1)2)

= sqrt((6+6)2+52)

 = sqrt(144+25)

= sqrt(169)

Step-by-step explanation:

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. The average rate of change in T(d) for the interval d = 4 and d = 10 is 0. Which statement must be true?The same number of tickets was sold on the fourth day and tenth day.No tickets were sold on the fourth day and tenth day.Fewer tickets were sold on the fourth day than on the tenth day.More tickets were sold on the fourth day than on the tenth day.

Answers

Answer:

The same number of tickets was sold on the fourth day and tenth day.

Step-by-step explanation:

Given, T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was  released.

The average rate of change in a function with respect to the independent variable gives the value of change in a particular period.

If average rate of change in T(d) for the interval d = 4 and d = 10 is  is 0 , that means nothing has been changed in the number of tickets sold on 4th day and 10th day after the film release.

Hence, the correct statement is "The same number of tickets was sold on the fourth day and tenth day."

Answer:

In simpler terms, for the edge answer;

A. The same number of tickets was sold on the fourth day and tenth day.

A jar has 20 marbles: 3 green, 12 blue, 5 red.

What is the probability of randomly choosing a red and then a green marble (keep the red marble when you choose it)?

Answers

Probability is defined as the likelihood or the certainty that an event is going to occur or happen.

The probability of randomly choosing a red and then a green marble is [tex]3/76[/tex].

The total number of marbles = 20

The number of green marbles= 3

The number of blue marbles = 12

The number of red marbles = 5

The probability of choosing a red marble = Number of red marbles / Total number of marbles

= 5/20

In simplest fraction form = [tex]\frac{1}{4}[/tex]

We are told in the question that you keep the red marble you choose, So this means the total number of marbles left reduces to 19

The probability of choosing a green marble is =  Number of green marbles / New total number of marbles

= 3/19

Therefore, the probability of randomly choosing a red and then a green marble is

P (Red) x P(Green)

= 1/4  x 3/19

= [tex]3/76[/tex]

If g(3) = 5 and g(-1) = 5, explain why g(x) does not have an inverse.

g(x) cannot have an inverse because it gives the same output value for two individual input values.

In this case, g(x) is 5 when x is both 3 and -1. Hence, g(x) does not have an inverse.
