Answer:

Zero

Step-by-step explanation:

because, if the Discriminant of f is positive, it intersects the x-axis twice; if it’s negative, it intersects the x axis 0 times, but if it intersects the x axis or touches it in 1 point, then the Discriminant is 0!

As you can see in this graph, the x-axis and parabola only touch/intersect in 1 point, so the Discriminant of f is zero

Hope this helps!

Answer: Discriminant is zero

Step-by-step explanation:

If negative, the vertex of the graph will be above the x-axis, if positive it will be below the x-axis, and zero if it is directly on the x-axis.

Answer:

6 hours

Step-by-step explanation:

Ashley drives 55 miles per hour. She drives about 65 miles every day. At this rates, how many hours will it take Ashley to drive 330 miles?

Doing the math it leads up to being six hours because 4 is too little unless she were speeding but it states clearly her speed and miles, so 6 hours is the answer

Answer:

13. $18.60

14. $15.79

Step-by-step explanation:

13.

Jeff starts off with $46.18

He then gives half of his money to his brother (so divide starting money by 2)

46.18 / 2 = 23.09

He now has $23.09

He then buys two donuts for $0.75 each ( 0.75 * 2 = 1.50 ) and a cup of coffee for $2.99 ( so he spent a total of 4.49 ) so we then subtract 4.49 from 23.09

23.09 - 4.49 = 18.6

He had $18.60 left over

14. 5 friends split a 65.20 bill at a restaurant

65.20 / 5 = 13.04

they also each left a $2.75 tip

13.04 + 2.75 = 15.79

They each payed $15.79

Answer:  Jeff has $18 dollars and 6 cents or $18.6

Step-by-step explanation:

Half of $46.18 is $23.09. Then if he bought two donuts and each donut cost $0.75 then you plus $0.75 + $0.75 = 1.5. You then minus $ 1.5 from your current $23.09 dollars, which will equal $21.59. You have to minus the coffe amount which will is $2.99 . You minus $21.59 - $2.99 =$18.6.

Answer:

No, the slope with the equation is 1/5 and the slope of the table is 2/1  or 2

Step-by-step explanation:

Slope is the change in y over the change in x.

Equation

y = mx + b when an equation is written in the slope intercept form of a line, the m is the slope.

y = \(\frac{x}{5}\) - 3  can be writing

y = \(\frac{1}{5}\) x - 3  It is easier to see that the slope is \(\frac{1}{5}\)

Table

Look at the y's.  The are change by 2 each time.  Now, look at the x's.  They are changing by 1 each time.  So, the slope is:

\(\frac{2}{1}\) or just 2

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Step-by-step explanation:

Bag A contains 9(5/9) pounds of coffee

Bag B contains 9(2/3) pounds of coffee

Which bag contains less coffee?

          ( 2/3) is the same as (6/9)

Now that the denominators are the same, if we compare the numerators, 5 is less than 6 (5 parts of 9 is less than 6 parts of 9)

Bag A contains less coffee than bag B

9(5/9) < 9(2/3)

Step-by-step explanation:

You want to know how many triangles can be formed from segments of lengths 1.6 m, 2.9 m, and 4.7 m.

The triangle inequality requires the sum of the two shorter segments exceed the length of the longest one.

  1.6 + 2.9 > 4.7

  4.5 > 4.7 . . . . . . . not true — no triangle can be formed

These segments will form no triangles.

Answer:

-4+ -1 = -5 which is less that -4

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

No; There is no constant of proportionality.

Step-by-step explanation:

29.98 divided by 50 is 0.5996 and 15.49 divided by 25 is 0.6196. They are not proportional nor are they equal. There is a difference of 0.02.

The scientific estimated form of the numbers are,

0.0000000043 = 4×10⁻⁹, 43560000000 = 4×10¹⁰, 56234567 = 5×10⁷, 0.000023456 = 2×10⁻⁵.

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in the scientific form in a compact manner.

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.
