Step-by-step explanation:

The minimum/maximum value of the function y = a(x − 2)(x − 1) occurs at x = d, what is the value of d?

Answers

Answer:

[tex]d=\frac{3}{2}=1.5[/tex]

Step-by-step explanation:

We have the function:

[tex]y=a(x-2)(x-1)[/tex]

And we want to find x=d for which the minimum/maximum value will occur.

Notice that our function is a quadratic in factored form.

Remember that the minimum/maximum value always occurs at the vertex point.

And remember that the x-coordinate of the vertex is the axis of symmetry.

Since a quadratic is always symmetrical on both sides of its axis of symmetry, a quadratic’s axis of symmetry is the average of the two roots/zeros of the quadratic.

Therefore, the value x=d such that it produces the minimum/maximum value is the average of the two roots.

Our factors are (x-2) and (x-1).

Therefore, our roots/zeros are x=1, 2.

So, the average of them are:

[tex]d=\frac{1+2}{2}=3/2=1.5[/tex]

Therefore, regardless of the value of a, the minimum/maximum value will occur at x=d=1.5.

Alternative Method:

Of course, we can also expand to confirm our answer. So:

[tex]y=a(x^2-2x-x+2)\\y=a(x^2-3x+2)\\y=ax^2-3ax+2a[/tex]

The x-coordinate of the vertex is still going to be the place where the minimum/maximum is going to occur.

And the formula for the vertex is:

[tex]x=-\frac{b}{2a}[/tex]

So, we will substitute -3a for b and a for a. This yields:

[tex]x=-\frac{-3a}{2a}=\frac{3}{2}=1.5[/tex]

Confirming our answer.

A cell phone costs $120. The price is reduced 30% for a sale. How much is the savings?

Answers

Answer:

the phone is 84 dollalrs

Step-by-step explanation:

Answer:

$36

Step-by-step explanation:

Since 30% = 30/100 then we can transform it into a decimal:

30%=0.30

Now if we multiply 120•0.30, we will get how much we saved.

$36, we saved $36.

Bonus information:

If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.

Answers

Answer:

SEE IN THIS U WILL GET THE ANSWER

The set of values {29, 43, 59} contain possible solutions for g option (B) {29, 43, 59} is correct.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequality is:

0.08g + 0.2 < 5

Plug g = 29

0.08(29) + 0.2 < 5

2.52 < 5 (True)

Plug g = 43

0.08(43) + 0.2 < 5

3.64 < 5 (True)

Plug g = 59

0.08(59) + 0.2 < 5

4.92 < 5 (True)

Thus, the set of values {29, 43, 59} contain possible solutions for g option (B) {29, 43, 59} is correct.

You may determine the slope of the line by determining the rise and the run using two of the line's points.

What is Slope of the line?A line's slope is the change in y coordinate in relation to the change in x coordinate. The net change in y-coordinate is denoted by y, while the net change in x-coordinate is denoted by x. Where "m" represents the slope of a line. As a result, tan represents the slope of a line. Calculate the difference in y-coordinates between these two points (rise). Determine the x-coordinate difference between these two points (run). Divide the y-coordinate difference by the x-coordinate difference (rise/run or slope). The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

Therefore,

You may determine the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two points. Rise divided by Run gives you the slope. Run = rise + slope Rise + run = slope.

So then they give you 3 1/2 inches on the board. You would see how many 1/2 inches there are in 3 1/2, which is 7, and multiply 7 by 12. The answer would be 84 feet. So they are say that 3 1/2 inches on the poster board, represents 84 feet in the real room.

Can someone please give me an answer.

Answers

It is not A. It’s B!
The reason it’s B is because when you look at the table, the y- intercept (or where it’s at when it’s at 0) is -75.
So you know it’s
Y= (something) -75
When you look at the rest of the table you can see that for every five it’s going up on the left side, it’s going up 25 on the right side.
If you divide 25 by 5 to figure out how much it is going up per 1 time instead of 5, you will get 5. You have to add X to that because that is the slope or how much you are going up by.
That means your equation is...
y=5x-75, or B!
Hopefully that helps you!

The answer is y=5x-75 or B

A measuring scoop holds 10 cm3 of flour. Brandon's bag of flour contains 90 scoops. How many cakes can Brandon bake with his flour if his recipe calls for 180 grams of flour per cake? 1 cm3 of flour weighs 0.6 grams.

Answers

The number of cakes that Brandon can bake with his flour given the recipe is 8.

How many cakes can he bake?

The first step is to determine the total cm³ of flour that is the bag of flour: 10cm³ x 90 = 900 cm³

Now, convert the answer gotten above to grams:

900 / 0.6 = 1500

The last step is to divide 1500 by 180

Which term best describes the graph of y = –2?

constant

positive

Answers

Answer:

It would be constant.

Step-by-step explanation:

Since there is no x value, the line will have no slope and just be horizontal about y= -2.

If we draw the graph we will see that the function is a straight line parallel to the x-axis.

The graph y = -2 is best described as a constant function.

Option C is the correct answer.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

A function:

y = -2

To graph the function we will find the coordinates of the function y = -2.

For x = 0,

y = -2

For x = 1,

y = -2

For x = 2,

y = -2

For x = 3,

y = -2

We will see that for all x values the y value is -2.

If we draw the graph we will see that the function is a straight line parallel to x-axis.

Thus,

The graph y = -2 is best described as a constant function.
