Answer:

40 minutes

Step-by-step explanation:

 Math Problems                   3              15

 ----------------------                  -----     =    ------

       Minutes                          8              x

                                             3x = 15 * 8

                                               x = 15 * 8 / 3

                                               x = 120 / 3

                                               x = 40

                                                  40 Minutes

Write a rule for the nth term of the arithmetic sequence. Then graph the first six terms of the sequence. a6=-12 a12=-36
denis-greek [22]

Answer:

We need to find the first term.  We can use the formula

an = a1 + d(n - 1)

to solve for a1.  We already know the 12th term, a12, common difference, d, and nth sequence, n.

a12 = -36

d = -4

n = 12

-36 = a1 - 4(12 - 1)

-36 = a1 - 44

8 = a1

The first term is 8.  Therefore, your formula is

an = 8 - 4(n - 1)

an = -4n + 12

Then use this formula to graph.

n is the independent variable.

an is the dependent variable.

Your graph will be a line.

1          8

5         -8

Zane calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle is it?
topjm [15]
The pythagorean theorem states that for any RIGHT-ANGLED TRIANGLE, the relationship between the side lengths are A²+B²=C², where C is the hypotenuse :P

Which means that it can only be applied on right angled triangles~
So your answer would be B, a right-angled triangle.

hello again I need to find an equation to find the long side of the triangle. but this time only the hypotenuse is given. brainl
Hunter-Best [27]

Answer:

The answer to your question is Long = 10.39

Step-by-step explanation:

Data

hypotenuse = 12

long = ?

Process

1.- To find Long, we must use the trigonometric functions sine or cosine.

If we use sine, we use the 60° angle

If we use cosine, we use the 30° angle

a) sin 60 = long / hypotenuse

   Long = hypotenuse x sin 60

   Long = 12 x sin 60

   Long = 10.39

b) cos 30 = Long / hypotenuse

   Long = hypotenuse x cos 30

   Long = 12 x cos 30

  Long = 10.39
