Question 1 (1 point)
Which equation can be represented by a graph with a vertex at (1,3)?

Answers

Answer 1

Answer:

The equation should be g(x) = x - 1 + 3.

Calculation of the equation:

Since the graph contains the vertex of (1,3)

The quadratic equation should be in the form of

$f(x) = (x - h)^2 + k$

Here (h,k) is the vertex, and 'a' is a constant.

So based on this, we can say that The equation should be g(x) = x - 1 + 3.

Answer 2

Answer:

Answer:

See explanation

Step-by-step explanation:

You have not provided the options to help us give you a specific answer.

If a quadratic function is written in the form

$f(x) = a {(x - h)}^(2) + k$

Then (h,k) is the vertex, and 'a' is a constant.

For instance

$f(x) = 5 {(x - 1)}^(2) + 3$

has vertex at (2,3).

Also, an absolute function in the form

$g(x) = a |x - h| + k$

has vertex at (h,k).

This means

$g(x) = |x - 1| + 3$

also has vertex at (1,3).

I hope this explanation is helpful.

Henry is hanging flyers on front doors for his father's pizza business. He hung 130 flyers in 95 minutes. He still has 870 flyers to hang. His brothers, Nick and Adam, come to help. Nick hangs flyers 50% faster than Henry, and Adam hangs flyers 20% slower than Henry. Find the constant of proportionality for the flyer hanging rate of Henry, Nick, and Adam combined? (round to nearest tenth)

Answers

Given:
Henry: 130 flyers in 95 minutes.
Nick hangs flyers 50% faster than Henry
Adam hangs flyers 20% slower than Henry
Remaining flyers: 870

Henry's rate per minute = 130/95 = 1.37 flyers per minute

Nick: 1.37 * 1.50 = 2.055 or 2.06 flyers per minute
Adam: 1.37 * 0.80 = 1.095 or 1.10 flyers per minute

1.37 flyers + 2.06 flyers + 1.10 flyers = 4.53 flyers per minute.

870 flyers ÷ 4.53 flyers per minute = 192 minutes

the constant proportionality for the flyer hanging of all three is 4.53 flyers per minute. They will finish hanging the remaining 870 flyer within 192 minutes.

the answer is 4.53 but you have to round to the nearest tenth so you get 4.5

Step-by-step explanation:

Even though theres another way to solve this, I'll use graphing since we already have all the options for points

the point in blue is D, the fourth vertex. I graphed all other points and none of them made a parallelogram so student 2 is right.

What is Rounding Numbers?

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is lessaccurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

There are some basic rules that need to be followed for rounding numbers.

We first need to know what our rounding digit is. This digit is the one that will ultimately be affected.
After this, we need to check the digit to the right of this place which will decide the fate of the rounding digit.
If the digit to the right is less than 5, we do not change the rounding digit. However, all the digits to the right of the rounding digit are changed to 0.
If the digit to the right is 5 or more than 5, we increase the rounding digit by 1, and all the digits to the right of the rounding digit are changed to 0.

Given:

3 3/8

Solving the mixedfraction

= 27/8

=3.375

= 3 ( nearest whole number)

Now, to round off nearest whole number will be 3
