Fourteen is 6 less a number (n). Which equation shows this relationship?

Answer:

h = A ÷ ½(a - b)

Step-by-step explanation:

A = ½ah - ½bh

A = ½h( a - b)

Divide both sides by the coefficients of h

A ÷ ½(a - b) = h

Answer:

a1- 2 terms

a2- 6x, 9y

a3- 6,9

Answer:

Step-by-step explanation:

The vertex can be located most easily by completing the square of

f(x) = -X^2 - 2x - 1 (which is equivalent to -(x^2 + 2x + 1).  The latter expression can be rewritten as -(x + 1)^2, which indicates that the x-coordinate of the vertex is -1.  The corresponding y-value is 0.  Vertex is at (-1, 0).

The function is increasing for x < -1 and decreasing for x > -1.

The domain of the function is "all real numbers."

The range is (-infinity, 0)

Answer:

Point V.

Step-by-step explanation:

Given the coordinates of T at (-6.5, 1), U represents T before any reflections. (Helps to visualize this better)

Reflecting across the x-axis results in the sign of the y-coordinate changed. Point T after this reflection becomes (-6.5, -1).

Finally, reflecting across the y-axis will change the sign for the x-coordinate.

(-6.5, -1) becomes (6.5, 1). This is represented by point V.

Answer: (1 and 22/45)

Step-by-step explanation:

I guess that we are working with mixed numbers here, and we have the equation:

(8÷2 2/9) − (2 11/15)

first we solve: 8÷2 = 4.

Now, we can write this as:

(4 + 2/9) - (2 + 11/15)

(4 - 2) + (2/9 - 11/15)

now, 9*5 = 45

        15*3 = 45

then we can write the right side as: 2/9 - 11/5 = 10/45 - 33/45 = -23/45

2 - 23/45

But in mixed numbers we also need to work with a positive rational, then we have:

2 - 23/45 = 1 + 1 -23/45 = 1 + 45/45 - 23/45 = 1 + 22/45

then the solution is:

(1 and 22/45)

Answer:

B) (x^2-2x)/(2x+6)

Step-by-step explanation:

When dividing fractions, it's just like multiplying the reciprocal of the second fraction : x/y divided by z/w = x/y * w/z.

We use that and we get (x-2)/(x+3) * x/2. we simplify and get x(x-2)/2(x+3). So Our answer is B

Answer:

The vertex is ( -1/2, 3/4)

Step-by-step explanation:

f(x)=x^2+x+1

The vertex form is

y = a( x-h) ^2 +k where (h,k) is the vertex

Rewriting the function by completing the square

Taking the coefficient of x and dividing by 2 and squaring it

(1/2) ^2 = 1/4

Adding it and subtracting it

f(x) = x^2 + x + 1/4 -1/4 +1

    = ( x^2+ x +1/4) + 3/4

   = ( x+ 1/2) ^2 + 3/4

 = ( x- -1/2) ^2 + 3/4

The vertex is ( -1/2, 3/4)

Answer:

[tex]6 \pm 2.861(0.3354)[/tex]

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 20 - 1 = 19

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.861.

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.861\frac{1.5}{\sqrt{20}} = 2.861(0.3354)[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The format of the confidence interval is:

[tex]S_{M} \pm M[/tex]

In which [tex]S_{M}[/tex] is the sample mean

So

[tex]6 \pm 2.861(0.3354)[/tex]

Hello! :) The answer will be under “Explaination”

Step-by-step explanation:

The correct answer to your question is 4 1/3

Here is the work:

So if we simply 39/9 we will get 13/3

Than we divide 3 and 13

Which will leave us with 4 and 1 left over

So the answer is 4 1/3

Here is how to check your work, 4x3 =12 and 12+1=13 (13/3 which equals to 39/9

Step-by-step explanation:

125 since it increased by 25%. look at the problem below:

125( 1 + 0.01d) then you plug those numbers in and theres your answer :00!!

sammy-6th grade-

The algebraic expression is 1.5d+150.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that 120 is increased by d % and increased by 25% then the expression will be written as below.

E = 1.5d+150.

Answer:

Yup P is the right one having 62.26%

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

We can set it up as

P = 33/53

Q = 20/48

R = 54/90

S = 44/83

This is because we are calculating the percent of yellow birds in the total amt. of birds in a specified park.

Now we calculate =>

P = 33/53 = around 0.62

Q = 20/48 = around 0.416

R = 54/90 = 0.6

S = 44/83 = around 0.53

We find that Park P has the greatest percentage and -->

Thus, Park P is our answer and yes, you are correct.

Answer:

equilateral

Step-by-step explanation:

There are various types of triangles out there, each with its own unique characteristics that distinguish it from others.

One such triangle is called an equilateral triangle. Essentially, like its name suggests, this kind of triangle has all three angles equal (they're actually all equal to 60 degrees). Additionally, this triangle has all three sides that same, as well.

Thus, the answer is equilateral.

Just for future reference, here are a couple more types of triangles:

- Isosceles

These triangles have at least 2 sides equal to each other; in other words, an equilateral triangle is an example of an isosceles triangle. In addition, the two angles of an isosceles triangle opposite to the two equal sides are themselves congruent.

- Scalene

These triangles have all three sides different, which in turn means that all three angles are distinct.

- Acute

These triangles' angles are all less than 90 degrees. That's what "acute" means: less than 90 degrees.

- Obtuse

These triangles have exactly 1 angle that is larger than 90 degrees.

- Right

These triangles have exactly 1 angle that is equal to 90 degrees.

Answer:

After 25 years, Minneapolis will have 154,062 more residents than Anoka.

Step-by-step explanation:

First, let's write a function for each case.

For Anoka, the initial population is 18,000. The population grows 5.2% or 0.052 each year. Thus:

[tex]A(x)=18000(1.052)^x[/tex], where x represents the amount of years after 1994.

Inversely, for Minneapolis, the population decreases by 2.3% or 0.023. Another way to write this is that it in changes by 1-0.023 or .977 or 97.7%. Thus:

[tex]M(x)=390000(0.977)^x[/tex].

To find how many more people are living in Minneapolis than Anoka after 25 years, simply plug 25 into the functions and then subtract.

In Anoka, after 25 years, there will be:

[tex]A(25)=18000(1.052)^{25}\approx 63924[/tex] residents.

In Minneapolis, after 25 years, there will be:

[tex]M(25)=390000(.977)^{25}\approx217986[/tex] residents.

217986-63924=154,062 residents.
