ANSWER

Y-intercept: 3000

Slope:-275

Linear equation:y=-275x+3000

EXPLANATION

The straight line touches the y-axis at

(0,3000).

The y-intercept is b=3000

The line also passes through (2,2450).

The slope is calculated using the formula,

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

[tex] = \frac{3000 - 2450}{0 - 2} [/tex]

[tex] = \frac{550}{ - 2} = - 275[/tex]

The slope is -275.

The linear equation is given by:

[tex]y = mx + b[/tex]

[tex]y = - 275x + 3000[/tex]

Answer:

26 terms

Step-by-step explanation:

The n-th term of this sequence with a common difference of 5 and a first term of -2 is ...

an = -2 +5(n -1)

The sum of the first n terms is ...

(a1 +an)/2·n = (-2 -2 +5(n -1))/2 ·n = 1573

n(5n -9) = 3146

5n^2 -9n -3146 = 0 . . . . . quadratic in standard form

Using the quadratic formula, we can find the positive solution for n to be ...

n = (9+√((-9)^2-4(5)(-3146)))/(2·5) = (9+√63001)/10 = 260/10 = 26

26 terms must be added to give the desired sum.

Answer:

The vertex form of a quadratic equation is:

[tex]f(x) = (x-3)^2+4[/tex]

the minimum value of f(x) is [tex]y=4[/tex]

Step-by-step explanation:

Given a quadratic equation of the form [tex]f (x) = ax ^ 2 + bx + c[/tex] then the x coordinate of the vertex is

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

So for  [tex]f(x)=x^2-6x+13[/tex]

[tex]a=1\\b=-6\\c=13\\[/tex]

Therefore

The x coordinate of the vertex is:

[tex]x=-\frac{(-6)}{2(1)}[/tex]

[tex]x=3[/tex]

The y coordinate of the vertex is:

[tex]f(3)=(3)^2-6(3)+13[/tex]

[tex]y=f(3)=4[/tex]

By definition the minimum value of the quadratic function is the same as the coordinate of y of its vertex

So the minimum value  is [tex]y=4[/tex]

The vertex form of a quadratic equation is:

[tex]f(x) = a(x-h)^2+k[/tex]

Where

a is the main coefficient. [tex]a=1[/tex]

h is the x coordinate of the vertex. [tex]h=3[/tex]

k is the y coordinate of the vertex. [tex]k=4[/tex]

So the vertex form of a quadratic equation is:

[tex]f(x) = (x-3)^2+4[/tex]

Answer:

a.  [tex]f(x)=(x-3)^2+4[/tex]

b. The minimum value is 4

Step-by-step explanation:

The given function is: [tex]f(x)=x^2-6x+13[/tex]

We add and subtract half the square of the coefficient of x.

[tex]f(x)=x^2-6x+3^2-3^2+13[/tex]

This becomes: [tex]f(x)=x^2-6x+9-9+13[/tex]

The first three terms form a perfect square trinomial.

[tex]f(x)=(x-3)^2+4[/tex]

The function is now in the form:  [tex]f(x)=a(x-h)^2+k[/tex], where V(h,k) is the vertex.

Therefore the vertex is (3,4).

The minimum value  is the y-value of the vertex, which is 4.

Answer: Third and fifth option

3) The median is the number in the middle on an ordered set of data.

5) To find the middle of an even data set, find the average of the two middle numbers.

Step-by-step explanation:

Given a set of data ordered from lowest to highest, the median of the data is the number that is in the middle. In other words, it is a number x for which it is true that 50% of the data is greater than x and the other 50% of the data is less than x.

For example, for the following set of 7 data:

2, 3, [5], 8, 13

the median is 5.

If the data number is even, for example 10 data:

3, 5, 9, 12, [19, 21], 33, 35, 40, 69

The median is the average between the two data that are in the middle

[tex]\frac{19 +21}{2} = \frac{40}{2} = 20[/tex]

Note that the median only represents a partition of the ordered data set. Therefore, it is not affected by outlier. For example

2, 4, 4.5, 4.8, 5          Median = 4.5

2, 4, 4.5, 67, 1506     Median = 4.5

The median does not represent the difference between the highest and the lowest data.

Therefore the correct affirmations are:

3) The median is the number in the middle on an ordered set of data.

5) To find the middle of an even data set, find the average of the two middle numbers.

B. (-2, 0) and (1, 0)

Step-by-step explanation:

The equation can be factored as ...

y = 2(x^2 +x -2) = 2(x +2)(x -1)

The x-intercepts are the values of x where y=0, so will be the values of x that make one or the other of the binomial factors zero:

Answer:

50,000

Step-by-step explanation:

Set up a proportion:

300000 = 6x

50000 = x

Answer:

50000

Step-by-step explanation:

Find the "unit rate" for occupancy:  

1500 ft²

------------- = 250 ft²/person

6 people

Now multiply this unit rate by 200 people.  "people" drops out, and you are left with

250 ft²

--------------- * 200 people = 50,000 ft²

1 person

Enter 50000.  200 people will need 50000 ft² of housing.

Answer:

  square inch — is a unit of area, not volume

Step-by-step explanation:

Some volume measures have their own unit, like liters, cups, pints, quarts, gallons, bushels, or barrels.

Other volume units are the cube of a linear measure, such as cubic centimeters, cubic inches, cubic feet, or cubic meters.

Still other volume units are a hybrid of an area measure and a linear measure, such as acre-feet.

A measure that is the square of a linear unit is an area measure, not a volume measure.

Answer:

Step-by-step explanation:

"square inch" is a unit of area, not of volume.

Step-by-step Answer:

6 reindeer, from which we fly 5, in N1 ways.

Each of the five must be arranged in N2 ways.

The total number of arrangements is therefore N1*N2 arranglements.

Note: C(n,r) = n!/((r!(n-r)!)

N1 = 6 choose 5 = C(6,5) = 6!/(5!/1!) =  6 ways

(same as number of ways to choose 1 reindeer to be left out).

N2 = 5! ways (5 choices for the first, 4 choices for the second, 3 for the third, and 2 for the fourth, and 1 for the last) = 5*4*3*2*1 = 120 ways.

So total number of arrangements

= N1 * N2 = 6 * 120 = 720 ways.

Alternatively, you can line up the 5 vacant spaces and choose the first among 6 reindeer, second among 5, third among 4, fourth among 3, and the last one among 2 for a total of

6*5*4*3*2 = 720 arrangements.

Answer:

(2,1) is the only solution to the linear equation

Step-by-step explanation:

to solve, just plug in the values given into the orignal expression. remember, the answer on the left has to be equal to the answer on the right.

Answer:

Step-by-step explanation:

if the temp is -8°F and you add 19 your new temp is 11°F

Final answer:

To find the final temperature after a rise of 19°F from -8°F, define the variable T as the final temperature, and use the expression T = initial temperature + temperature change, which evaluates to T = 11°F.

Explanation:

The student is asked to determine the temperature after a rise of 19°F from an initial temperature of -8°F. To solve this, let's define the variable T to represent the final temperature. The expression to find the final temperature after the rise would be:

T = initial temperature + temperature change

In this case, the initial temperature is -8°F and the temperature change is a rise of 19°F, so the expression becomes:

T = -8°F + 19°F

When we evaluate this expression:

T = 11°F

Therefore, the temperature after a rise of 19°F from -8°F is 11°F.

Answer:

Step-by-step explanation:

Cost per item is found by dividing the cost by the number of items. If the woman bought n items for $120, the cost of each item is $120/n. If the woman bought 24 more items, n+24, at the same price, then the cost per item is $120/(n+24). The problem statement tells us this last cost is $16 less than the first cost:

120/(n+24) = (120/n) -16

Multiplying by n(n+24) gives ...

120n = 120(n+24) -16(n)(n+24)

0 = 120·24 -16n^2 -16·24n . . . . . . subtract 120n and collect terms

n^2 +24n -180 = 0 . . . . . . . . . . . . . divide by -16 to make the numbers smaller

(n +30)(n -6) = 0 . . . . . . . . . . . . . . factor the quadratic

The solutions to this are the values of n that make the factors zero: n = -30, n = 6. The negative value of n has no meaning in this context, so n=6 is the solution to the equation.

The woman bought 6 items.

Check

When the woman bought 6 items for $120, she paid $120/6 = $20 for each of them. If she bought 6+24 = 30 items for the same money, she would pay $120/30 = $4 for each item. That amount, $4, is $16 less than the $20 she paid for each item.

Then, if a book in the bookcase has a mass of 400 grams and you need to find the number of books of the same mass that would take to equal the mass of the bookcase, you can divide the weight of the bookcase (in grams) by the weigth of one of these books.

Factors of 60:
