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

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

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.

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

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:

The correct answer is the last one 80(5 + x)

Answer:

C and B

Step-by-step explanation:

A. 12x = 3, x =1/4

C. 10 + x = 14, x = 4

B. 6x = 24, x =4

D. x -4 = 8, x =12

Only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
A
12x = 3

Simplifying the above expression,
12x = 3
x = 3 / 12
x = 1 / 4

Similarly simplifying all the expressions gives,
B. x = 4
C. x = 4
D. x = 12

Thus, only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.

-55 5/10000

Step-by-step explanation:

We can break each word down. Negative would be the negative sign (-), fifty-five would be 55, and five ten-thousandths would be 5/10000. If we put them together, we would get -55 5/10000, which is the answer.
