Answer:

y=x/2 (x divided by 2)

Step-by-step explanation:

2/1=1,4/2=2,8/2=4,10/2=5,16/2=8

The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different, [tex]-\pi/2, \pi[/tex] for sine and cosine respectively.

The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.

Here is a procedure, first take a derivative

[tex]\frac{d}{dx}(\sin x+\cos x)=\cos x -\sin x[/tex]

Then compute critical points of a derivative

[tex]\cos x-\sin x=0\implies x_1=\frac{\pi}{4},x_2=\frac{5\pi}{4}[/tex].

Then evaluate [tex]\sin x +\cos x[/tex] at [tex]x_1,x_2[/tex].

You will obtain global maxima and global minima [tex]\sqrt{2}, -\sqrt{2}[/tex] respectively.

The answer is [tex]-\sqrt{2}[/tex].

Hope this helps.

Answer:91 years

Step-by-step explanation:

26-4s=9s

⇔26=9s+4s

⇔26=13s

⇔s=2

Answer:

s = 2

Step-by-step explanation:

26 - 4s = 9s

add 4s to 4s and 9s

that equals 13

26/13 = 13s/13

s = 2

Answer:

Direct Variation

Step-by-step explanation:

Given: A car travels at a distance of [tex]d[/tex] km. The formula that relates [tex]d[/tex] to [tex]t[/tex] is [tex]d=kt[/tex]

To find: kind of variation

Solution:

The formula that relates [tex]d[/tex] to [tex]t[/tex] is [tex]d=kt[/tex]

Here, [tex]k[/tex] is a constant of proportionality.

Constant of proportionality is also called as constant of variation.

[tex]d[/tex] varies directly as [tex]t[/tex].

Therefore, this is a direct variation.

Answer:

Step-by-step explanation:

The perimeter of a rectangle is

P=2(L+W)

We are given L=3x+9 and W=2x-5 so

P=2(3x+9+2x-5)

P=2(5x+4)

P=10x+8

Hola 15 es tu respuesta

espero que esto ayude

ANSWER:

= 158 square inches

STEP BY STEP:

okay! so basically I like to ignore the net figure (just my personal opinion)

so we know that the rectangular prism has six sides (one top, one bottom, one front, one back, and two on each side)

so using that information, we can solve for the surface area!

FRONT AND BACK AREA:

- to solve for this area, we are going to take the 8" and multiply it by 5" to find the surface area of the front and the back panels

8*5 = 40 BUT WE HAVE TWO PANELS WITH THIS AREA

40*2 = 80

TOP AND BOTTOM AREA:

- to solve for this area, we are going to take 3" and multiply it by 8" to find the surface area of the top and bottom panels

3*8 = 24 BUT WE HAVE TWO PANELS WITH THIS AREA

24*2 = 48

SIDE AREA:

- to solve for this area, we are going to take 3" and multiply it by 5" to find the surface area of both the left and right sides

3*5 = 15 BUT WE HAVE TWO PANELS WITH THIS AREA

15*2 = 30

So now we have all of our areas and we will just add them together!

80+48+30

= 158 square inches

I hope this helped :)

Answer:

c i took the test and got that one right

Step-by-step explanation:

Answer:

20/3

Step-by-step explanation:

Every nth term takes the form of  a + n*d, where a is the first  term.

So 7th term = (54 = a + 7d), 13th term = (94 = a + 13d).

equate them both:

94 - 13d = 54 - 7d

40 = 6d

d = 40/6

Answer:

249

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

an = a1+d(n-1)

a1 is the first term so a1 = -39

d is the common difference so d = 8

n is the term number so n = 37

a37 = -39+8(37-1)

       = -39+8(36)

        = -39+288

        =249

Answer:

The length must be less than 20, and greater than 6.

6 < L < 20

Answer:

the first option

Step-by-step explanation:

equilateral triangles are also equiangular which means each of the three angles is 60°

but you can have an acute triangle with angle measures that are all acute (for example, 59°, 85°, and 36°) that is not equilateral
