Answer:

[tex]\huge\boxed{8}[/tex]

Find the constant of proportionality using

rise ( y value) / run ( x value):

Therefore:

8 / 1 = 8 = constant of proportionality

We can go ahead and check our work as well:

16 / 2 = 8

24 / 3 = 8

32 / 4 = 8

Therefore, 8 is the correct constant of proportionality.

[tex] \boxed{ \bold{ \boxed{ \sf{f( - 4) = 1}}}}[/tex]

Step-by-step explanation:

Given, f ( x ) = - x - 3

Let's find the value of f ( - 4 )

[tex] \sf{f( - 4) = - ( - 4) - 3}[/tex]

We know that , [tex]( - ) \times ( - ) = ( + )[/tex]

⇒[tex] \sf{ 4 - 3}[/tex]

Answer:

D (Presumably)

16 by 3

Step-by-step explanation:

The perimeter of a rectangle is the two lengths added with the two widths. In a formula, this is:

[tex]P=2l+2w[/tex]

Where l is the length and w is the width.

We are told the length is 13 units longer than the width. In other words:

[tex]l=w+13[/tex]

We also already know that the perimeter is 38 units. So, let's substitute P for 38 and l for (w+13) to solve for w:

[tex]P=2l+2w\\38=2(w+13)+2w[/tex]

Distribute:

[tex]38=2w+26+2w[/tex]

Combine like terms:

[tex]38=4w+26[/tex]

Subtract 26 from both sides:

[tex]12=4w[/tex]

Divide both sides by 4:

[tex]w=3[/tex]

Thus, the width is 3 units.

Since the length is 13 units longer than the width, the length is 16 units.

C. Setting up a booth in the lunchroom where students can give their thoughts

Step-by-step explanation:

Sampling is the process by which some part of the entire population is selected and researched. This selected population helps in estimating the researches for the entire population. There are various methods used for the process of sampling.

For the given case, the sampling method to be adopted is to view each students' opinion on the issue. For this process, setting up a booth can prove helpful as the opinion of every student can be viewed with no biases. Also, every student is free to provide their opinion with any fear.

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

The greatest number formed by those numbers is: 765420

The least number formed by those number is: 204567

The sum is: 765420 +  204567 = 969987

The difference is: 765420 -  204567 = 560853

Answer: Hi!

First we need to form the biggest and smallest number out of these digits. To do this it's pretty simple - just order the numbers from greatest to least for the greatest number, and from least to greatest for the least number! (However, for the least number, we will have to put the zero in front of 2, the second least number, because we can't put 0 in front of 2 and still be actually using it in the number.)

Greatest: 765420

Least: 204567

Now we add the numbers together:

765420 +  204567 = 969987

Now we subtract the numbers:

765420 -  204567 = 560853

These are your answers!

Hope this helps!

Answer: The 9th term is 16.

Step-by-step explanation:

Given formula : [tex]a_n=4(n-5)[/tex], where n is a natural number using for determine the terms.

To find the 9th term , we substitute n= 9 in the above expression, we get

[tex]a_9=4(9-5)\\\\\Rightarrow\ a_9=4(4)\\\\\Rightarrow\ a_9=16[/tex] which is the 9th term.

Hence, the 9th term is 16.

Answer:

Step-by-step explanation:

Hello, please consider the following.

We need to factorise as much as possible and eliminate the same term from numerator and denominator

[tex]\dfrac{\dfrac{x^2-4x-5}{x-2}}{\dfrac{2x-10}{x^2-4}}\\\\\\=\dfrac{(x^2-4x-5)}{(x-2)}\dfrac{(x-2)(x+2)}{(2x-10)}\\\\\\=\dfrac{(x-5)(x+1)(x+2)}{(2x-10)}\\\\\\\large \boxed{=\dfrac{(x+1)(x+2)}{2}}[/tex]

Answer:

f(x) =5x -6 and g(x) = x + 1

Step-by-step explanation:

5x^2 - x - 6

finding the product of AC where A is 5 and C is -6 equals -30

factors of -30 whose sum eqjals -1 are +5 and -6

substitute into the expression

5x^2 + 5x -6x - 6

group the expression

(5x^2 + 5x) (-6x - 6)

take out the common factors in each bracket

5x(x + 1) -6 (x + 1)

(5x - 6) (x + 1)

Answer:a

Step-by-step explanation:

Answer:

a) Vertex is at (-3, -1)

b) y-intercept is at (0,8)

c) x intercept is at (-4,0) and (-2,0)

d) x=-3

Step-by-step explanation:

We know the vertex is the lowest or highest part of a parabola meaning all the points are reflected across.  It is the only y value without a matching pair

E.x. -1 and 1, -3 and 3

The only point without a corresponding y value is (-3,-1) therefore the vertex is at (-3,-1)

The y-intercept is where the parabola meets the y axis or the x value is equal to 0, we just have to find when x = 0 to find the y intercept

y intercept: (0,8)

For the x intercept's it is just the reverse, you need to find where the parabola crosses the x axis or when y = 0

x intercept 1:(-4,0)

x intercept 2: (-2,0)

The axis of symmetry is also the x coordinate of the vertex which is 3 so

x = 3

Answer:

Answer:

  1, -0.5, -6.25

Step-by-step explanation:

The number in the left box is the leading coefficient. The coefficient of x^2 is 1, so that goes in the first box.

__

The number in the second box is half the coefficient of x, divided by the leading coefficient:

  (1/2)(-1)/1 = -1/2

__

The number in the third box (k) is the number required to make the rewritten g(x) match the original g(x). So far, we have ...

  g(x) = 1(x -1/2)^2 + k = x^2 -x -6

  x^2 -x +1/4 +k = x^2 -x -6 . . . . . expand the square

  1/4 +k = -6 . . . . . . . . . . . . . . . . . subtract the x-terms from both sides

  k = -6 1/4 . . . . . . . . . . . . . . . . . . subtract 1/4

So, you have ...

  [tex]g(x)=\boxed{1}(x+\boxed{-0.5})^2+\boxed{-6.25}[/tex]

Answer:

Step 2

Step-by-step explanation:

The addition property of equality was applied in step 2. The '- 9' value had to be 'undone', so '9' was added to each side of the equation, which would be an application of the addition property of equality, to yield step 3.

Hope this helps.

The correct option is A. Step 2.

Given the image in question as we saw in step 2, 9 has been added to both sides of the equation,right hand side and left hand side.

Hence in step 2 the addition property of equality applied.

So, the correct option is A. step 2.

Formatted Options:

A. sin²A−cos²A

B. sin²A+cos²A

C. cos²A−sin²A

D. cosA−sinA

Answer:

C. cos²A−sin²A

Step-by-step explanation:

From the double angle formulas, we know that:

cos (A + B) = cosAcosB - sinAsinB

So, if B = A, then the above equation becomes;

cos(A + A) = cosAcosA - sinAsinA      [i.e replacing B with A]

=>cos(2A) = (cosA)² - (sinA)²

=> cos(2A) = cos²A - sin²A

Therefore,

cos(2A) is equivalent to cos²A - sin²A

D) ƒ(x) + 2 = x^5 + 2

Answer:

annually

Step-by-step explanation:

Compound interest formula:

A = P(1 + r/n)^(nt)

amount of interest = balance - principal

Try daily:

A = 7775(1 + 0.045/365)^(365 * 14)

A = 14,597.88

This is too much money, so it was compounded less than daily.

Try monthly:

A = 7775(1 + 0.045/12)^(12 * 14)

A = 14,581.23

This is too much money, so it was compounded less than monthly.

Try quarterly:

A = 7775(1 + 0.045/4)^(4 * 14)

A = 14,547.16

This is too much money, so it was compounded less than quarterly.

Try annually:

A = 7775(1 + 0.045/1)^(1 * 14)

A = 14,398.87

This is the correct amount, so it was compounded annually.

Answer:

9 days

Step-by-step explanation:

Let x = days taken by C to do it alone

In one day, A can do: 1/12 (part of the whole work)

In one day, B can do: 1/18 (part of the whole work)

In one day, C can do: 1/x (part of the whole work)

In one day,together A, B and C can do: 1/4 (part of the whole work)

we have this equation:

1/x + 1/12 + 1/18 = 1/4

--> 1/x = 1/4 - 1/12 - 1/18 = 1/9

--> x = 9 (days)
