This question is incomplete because it lacks the diagram of the right angled triangle. Find attached to this answer the diagram of the right angle triangle.

Answer:

d-50

Step-by-step explanation:

Looking at the attached diagram, the only way to solve for this is the use of the trigonometric function. The trigonometric function to be used is the cosine function.

From the diagram, we are given

Hypotenuse = AB = 14

Adjacent = AC = 9

The measure of angle A to the nearest degree is calculated as:

cos θ = Adjacent / Hypothenuse

cos θ = 9/14

θ = cos -¹ (9/14) or arccos(9/14)

θ = 49.994799115°

To the nearest degree = 50°

Therefore,the measure of angle A to the nearest degree = 50°

Answer:

Step-by-step explanation:

here you go mate :)

step 1

2(x + 4) = -6 solving for x

step 2

2(x + 4) = -6 simplify by distributing

2x+8=-6

step 3

2x+8=-6 subtract 8

2x=-14

step 4

2x=-14 look for the number that can divide them both like 2

2x/2=-14/2

answer

x=-7

Please help thank you so so so much <br><br> there is more than one answer

Answer:

B and C work. A and D do not.

Step-by-step explanation:

This is one of those questions that you have to go through each answer to see what the results are. You don't have to go far to eliminate A and D so let's do that first.

5n + 6

Let n = 1

5(1) + 6

5 + 6= 11

However there is trouble beginning with n = 2

5*2 + 6

10 + 6

16 All you need is one wrong answer and the choice is toast. So A won't work.

================

Try D

6(n - 1)+ 5

n=0

6*(-1) + 5

-6 + 5

- 1

And D has been eliminated with just 1 attempt. n= 2 or n = 1 would be even worse. D is not one of the answers.

=============

Let n = 1

6(1) + 5

6 + 5

11 The first term works.

n = 2

6*(2) + 5

12 + 5

17 and n = 2 works as well. Just in case it is hard to believe, let's try n = 3 because so far, everything is fine.

n = 3

6*(3) + 5

18 + 5

23 And this also works. I'll let you deal with n = 4

========

n = 0

6(0 + 1) + 5

6*1 + 5

6 + 5

n = 1

6(1 + 1) + 5

6*2 + 5

12 + 5

17 which works.

So C is an answer.

Write the first four terms of the sequence defined by each of the following recursive formulas.

Dafna11 [192]

Answer:

First equation : 3, 0, -3, -6

Second equation : 2, 2.5, 3, 3.5

Step-by-step explanation:

What the first equation is basically saying is subtract 3 each time.

What the second equation is basically saying is add 0.5 each time.

Then we just add/subtract to find the first four terms.
