The terminal side of Ø is in quadrant IV and cos Ø + 5/13, what is sin Ø?

A. -5/12
B. -12/13
C. 12/13
D. 5/12

Answers

Answer:

It’s -12/13

Step-by-step explanation:

The value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

What is the trigonometric ratio?

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

We have:

The terminal side of Ø is in quadrant IV quadrant

cosØ = 5/13

sin²Ø = 1 - cos²Ø

sin²Ø  = 1 - (5/13)²

sinØ = √(144/169)

sinØ = -12/13 (negative in IV)

Thus, the value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

• On Monday the school bus traveled the Green Route 8 times and the Blue Route 9 times, traveling a total of 95 miles. • On Tuesday the school bus traveled the Green Route 12 times and the Blue Route 6 times, traveling a total of 102 miles

Answers

Answer: Green route = 5.8 miles

Blue route = 5.4 miles.

Step-by-step explanation:

Let the miles travelled for Green route be x

Let the miles travelled for Blue route be y

We can form an equation from the question given which will be:

8x + 9y = 95 ........ i

12x + 6y = 102 ......... ii

Multiply equation i by 12

Multiply equation ii by 8

96x + 108y = 1140 ....... iii

96x + 48y = 816 ....... iv

Subtract iv from iii

60y = 324

y = 324/60 = 5.4

Blue route is 5.4 miles.

Since 8x + 9y = 95

= 8x + 9(5.4) = 95

8x + 48.6 = 95

8x = 95 - 48.6

8x = 46.4

x = 46.4/8 = 5.8

Green route = 5.8 miles

Well if the <1+<2=180 then you can put the equation as 4x+10+x+20=180. We can simplify that to be 5x+30=180. Minus 30 from both sides: 5x=150; x=30

Point V lies between points U and W on Line segment U W.
If UW = 9x – 9, what is UW in units?

Answers

Answer:

See Below

Step-by-step explanation:

2x - 4 + 4x + 10 = 9x - 9

6x + 6 = 9x - 9

3x = 15  

x = 5  

UW = 9x-9 = 9*5-9  

UW = 36 units

Answer:

36

Step-by-step explanation:

UW = UV + VW

9x - 9 = 2x - 4 + 4x + 10

9x - 2x - 4x = -4 + 10 + 9

3x = 15

x = 5

UW = 9x - 9 = 9(5) - 9 = 45 - 9 = 36

Step-by-step explanation:

yes E has more but 9 out of 25 so she was supposed do even more than Alex she missed 16,alex got 8 out of 20 so he only  missed 12 of his shots and has fewer chances to make more.

No you have to also consider the number of attempts, not just the number of shots made. 9 out 1000 isn’t better than 9 out 10.

9/25 = 36%
8/20 = 40% alex is better.

solve the system of equations. y= x + 17, y= 3x+1

Answers

Answer:

x=8, y=25. As a point it's (8,25)

Step-by-step explanation:

here is the system:

y=x+17

y=3x+1

notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)

so it'll be:

3x+1=x+17

subtract 1 from both sides

3x=x+16

subtract x from both sides

2x=16

divide by 2

x=8

now, substitute 8 as x into one of the equations and solve for y

let's take the first one for example

y=8+17

y=25

so the answer is x=8, y=25. As a point it's (8,25)
