Given: SIn(A)= 4/5 ,pi/2 < A< pi and sin(B)= -2square5/5, pi < B < 3pi/2

What is the value of cos(A-B)

A. -2square5/25
B. -square5/5
C. 2square5/5
D. 11square5/25

Answer:

Step-by-step explanation:

Lines l and m are the parallel lines and line n is a transversal intersecting parallel lines.

Since, m∠2 = m∠4 = 118° [Given]

m∠2 = m∠6 = 118° [Corresponding angles]

m∠4 = m∠8 = 118° [Corresponding angles]

m∠1 + m∠2 = 180° [Linear pair of angles]

m∠1 = 180° - 118° = 62°

m∠1 = m∠5 = 62° [Corresponding angles]

m∠3 = m∠1 = 62° [Corresponding angles]

m∠7 = m∠5 = 62° [Corresponding angles]

Answer:

md(-2,-1)

Step-by-step explanation:

Md=(x1+x2/2,y1+y2/2)

or,Md=(-1-3/2,2-4/2)

Step-by-step explanation:

First you figure out that the shadow is 2.5 times larger than what is casting it. Then you divide 24 by 2.5.

Answer:

y=-3x-7

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,5) and has a slope of -3.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -3. So you can right away fill in the equation for a line somewhat to read:

y=-3x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-4,5). When x of the line is -4, y of the line must be 5.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).

So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-4,5). y=mx+b or 5=-3 × -4+b, or solving for b: b=5-(-3)(-4). b=-7.

Answer:

option 2 is the best answer

Step-by-step explanation:

I actually couldn't tell you 100% how i got this answer, but i narrowed it down to option 2 and option 3 because those ones have the inequality sign facing the correct way, and then I solved the inequalities to see which one made more sense, and option 3 came out as negative and you can't have a negative cost on something, so option 2 is the best answer.

Answer:

  400

Step-by-step explanation:

If x represents the number of employees a year ago, the current number is ...

  x + 0.33x = 53,200

  x = 53,200/1.33 = 400

The company had 400 employees a year ago.

Step-by-step explanation:

opening the bracket,the equation therefore is

-8x + 1 > 5 - 3x

add 8x to both sides

- 8x + 8x +1 > 5 - 3x + 8x

1 > 5 + 5x

subtract 5 from both sides

1 - 5 > 5 - 5 + 5x

-4 > 5x

Divide through by 5

-4/5 > x

which is therefore written is

x < -4/5

810 minutes

if u add ten to 219 each time u will get 13 and 5 left which is 13.5 and 13.5 in minutes equals 810

Answer:

5.15

Step-by-step explanation:

17.51 / 3.4 = 5.15

Answer and Explanation

__________________________________________________________

We can prove this is the answer by dividing both numbers.

__________________________________________________________

[tex]17.51[/tex] = [tex]\frac{1751}{100}[/tex]

[tex]3.4[/tex] = [tex]\frac{17}{5}[/tex] = [tex]3\ \frac{2}{5}[/tex]

__________________________________________________________

[tex]\frac{1751}{100}[/tex] [tex]\div[/tex] [tex]\frac{17}{5}[/tex] = [tex]?[/tex]

__________________________________________________________

So, that means the answer is [tex]5.15[/tex]

Answer:

1 = 61

4 = 119

Step-by-step explanation:

Alternate angles

Answer:

1 = 61 and 4=119

Step-by-step explanation:

If 2=119 then the other side of the angle which is 1 has to equal the sum of 180-119

if you reflected 2 across the x and y axis or in other words swapped places with the angel diagonal from it, this should answer the same thing as 2 hence why 2 equals 4 equals 119

3 would equal 1 which equals 61 as they both make 180 when paired with the angle directly next to it

f(3) = (1/9)(9*(3))

     = 1/9 * 27

      = 3

Answer:

Revenue = $8.44

Profit = $1.69

Step-by-step explanation:

Answer:

f(3) = 11

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 2(3) + 5 = 6 + 5 = 11

When they create 3.44 products and make a revenue of $76.027, they will break even.

Step-by-step explanation:

To do this, simply graph the 2 equation in a graphing calculator and analyze the graph for where the 2 graphs intersect. Discard the negative intersection because we cannot have a negative production. You should see that your intersection point is (3.441, 76.027).
