Taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. Provide Taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1g(x)=2x^2+1

Answers

Answer 1
Answer:

Answer:

f(x)=g(x) at x= 0 and x= 1 and not at x= 3.

Step-by-step explanation:

We have the functions, f(x)=2x+1 and g(x)=2x^2+1.

It is given that,

At x=0, x=1, and x=3, f(x)=g(x)

i.e. 2x+1=2x^2+1

i.e. 2x^2-2x=0

i.e. 2x(x-1)=0

i.e. x= 0 and (x-1)= 0

i.e. x= 0 and x= 1.

Also, after plotting the graphs of both the functions, we see their intersection point are (0,1) and (1,3).

Thus, we get that f(x)=g(x) at x= 0 and x= 1 and not at x= 3.

Amir arranged 9 photos on a bulletin board. He put the photos in rows. Each row contains the same number of photos. How many photos could be in each row?

Answers

Answer: There will be 3 rows with 3 photos.

Step-by-step explanation:

Since we have given that

Number of photos to be arranged by Amir on a bulletin board = 9

According to question, we have given that each row contains the same number of photos.

Let the number of rows be x

So, the number of photos also be x

So, our equation becomes

x^2=9\n\nx=√(9)\n\nx=3

So, there will be 3 rows with 3 photos.

What can be multiplyed by 3 to equal 40

Answers

Let's say that the number we are looking for is called 'x'.

3 * x = 40
3x = 40

To solve for 'x', we will need to divide both sides by 3.

3x/3 = 40/3

x = \boxed{\bf{(40)/(3) = 13(1)/(3)}}

40/3 or 13 1/3 can be multiplied by 3 to get 40.

Anita has $300 in her savings account that earns 5% annually. The interest is not compounded. How much interest will she earn in 1 year?

Answers

Answer:

$15

Step-by-step explanation:

We are given that

Anita has money in her saving account=$300

She earns annually=5%

We have to find the value of interest she will earn in 1 year when the interest is not compounded.

P=300, r=5%,t=1

To find the value of interest we will use the formula of simple interest.

Simple interest,I=(P* r* t)/(100)

Substitute the values in the formula then, we get

Interest=(300* 5* 1)/(100)=15

Hence, she will earns interest in 1 year=$15
300 x 0.05 = 15

So she will earn $15 of interest in 1 year

Paula earns a weekly salary of $890 plus 5% commission. Last week, she sold $3250 worth of products. What was her gross pay?$1097.00
$1052.50
$890.00
$162.50

Answers

The total gross pay will be $1052.50. The correct option is B.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Paula earns a weekly salary of $890 plus a 5% commission. Last week, she sold $3250 worth of products.

The commission is the part of the sales you made that you get

A 5% commission means she gets 5% of what she sold

5% of 3250=0.05 times 3250=162.5

The gross pay will be calculated as,

salary+comission=gross pay (no tax)

890+162.5=$1052.50

You cannot bisect an angle using paper folding constructions True or False

Answers

Answer:

The given statement:

You cannot bisect an angle using paper folding constructions is a False Statement.

Step-by-step explanation:

The construction of a angle bisector with the help of paper folding is done by:

  • Draw a angle ACB on a piece of paper such that the ray CB lie on the base.
  • Fold the paper in such a way that ray AC falls along the ray CB.
  • draw the line along the crease that is formed on the paper starting from point C.
  • So, the ray so formed is the angle bisector of the angle ACB.
