Answer:

$a_{n}$ = 3n + 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence

10 - 7 = 13 - 10 = 16 - 13 = 3

This indicates the sequence is arithmetic with nth term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 3 , then

$a_{n}$ = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Is there a series of rigid transformations that could map ΔQRS to ΔABC? If so, which transformations could be used?

faltersainse [42]

Answer;

D Yes, ΔQRS can be translated so that Q is mapped to A and then reflected across the line containing QS.

Explanation;

-A rigid transformation is a transformation of a plane that preserves length. It is also called isometry. Reflections, translations, rotations, and combinations of these three transformations are examples of rigid transformations.

You are designing a rectangular poster to contain 7575 in2 of printing with a 33-in margin at the top and bottom and a 11-in m

erma4kov [3.2K]

Answer:

The dimensions of the rectangular poster is 15 in by 5 in.

Step-by-step explanation:

Given that, the area of the rectangular poster is 75 in².

Let the length of the rectangular poster be x and the width of the rectangular poster be y.

The area of the poster = xy in².

$\therefore xy=75$

$\Rightarrow y=\frac{75}{x}$ ....(1)

1 in margin at each sides and 3 in margin at top and bottom.

Then the length of printing space is= (x-2.3) in

=(x-6) in

The width of printing space is = (y-2.1) in

=(y-2) in

The area of the printing space is A =(x-6)(y-2) in²

∴ A =(x-6)(y-2)

Putting the value of y

$\Rightarrow A =(x-6)(\frac{75}{x}-2)$

$\Rightarrow A = 87-\frac{450}{x}-2x$

Differentiating with respect to x

$A '= \frac{450}{x^2}-2$

Again differentiating with respect to x

$A''=-\frac{900}{x^3}$

To find the minimum area of printing space, we set A' = 0

$\therefore \frac{450}{x^2}-2=0$

$\Rightarrow 450 =2x^2$

$\Rightarrow x^2=225$

$\Rightarrow x=\pm 15$

Now putting x=±15 in A''

$A''|_{x=15}=-\frac{900}{15^3}$

$A''|_{x=-15}=-\frac{900}{(-15)^3}=\frac{900}{(15)^3}>0$

Since at x=15 , A"<0 Therefore at x=15 , the area will be minimize.

From (1) we get

$y=\frac{75}{x}$

Putting the value of x

$y=\frac{75}{15}$

=5 in

The dimensions of the rectangular poster is 15 in by 5 in.

(6e-3f-3/4) in a equivalent expression

pashok25 [27]

Answer:

Step-by-step explanation:

(6e-3f-3/4) contains two terms which do not involve fractions and one fractional term (3/4).

We can safely remove the parentheses. Then:

(6e-3f-3/4) => 6e - 3f - 3/4

That is "an equivalent expression."

We could go further and create one equivalent fraction. Multiply the first two terms by 4/4, obtaining:

24e 12f 3 24e - 12f - 3 3(8e - 4f - 1

------ - ------ - ----- => ---------------------- => -------------------

4 4 4 4 4

Other equivalent expressions exist here.
