Answer:

<h3>L = 60°</h3><h3>M = 50°</h3><h3>N = 30°</h3><h3>P = 40°</h3><h3 />

Step-by-step explanation:

inside angle = 180 = 2x + 2x + 20 + 3x - 10 + 2x - 10

  • 180 - 20 + 10 + 10 = 2x + 2x + 3x + 2x
  • 180 = 9x
  • x = 180 / 9
  • x = 20

<u>substitute the value of x = 20 into angle L, M, N, P</u>

L = 2x + 20

L = 2(20) + 20

<h3>L = 60°</h3>

M = 3x - 10

M = 3(20) - 10

<h3>M = 50°</h3>

N = 2x - 10

N = 2(20) - 10

<h3>N = 30°</h3>

P = 2x

P = 2(20)

<h3>P = 40°</h3><h3 /><h3>check:</h3>

∠L + ∠M + ∠N + P = 180

60° + 50° + 30° + 40° = 180

The terminal side of angle θ intersects the unit circle in the first quadrant at (16/19,y). What are the exact values of sinθ an
Lelechka [254]

The exact value of sin θ  and cos θ  is: sinθ =(√105)/19 and cosθ =16/19

The terminal side of an angle is the angle at the standard position. The terminal side of an angle θ drawn in angle standard position is the side which isn't the initial side.

Given that the point of intersection of the terminal side of θ an the unit circle is:

(16/19,y)

The exact value of sin θ  and cos θ  is: sinθ =(√105)/19 and cosθ =16/19

The given parameters is represented by:

(16/19,y)

This means that :

(cosθ ,sinθ )=(16/19,y)

Using the following trigonometric identity:

cos²θ +sinθ =1

We have:

(16/19)²+y²=1

Expand fraction:

(256/361)+y²=1

Collect like terms:

y²=1-(256/361)

Take LCM:

y²=(361-256)/361

y²=105/361

Take square roots

y=(√105)/19

Substitute value for y in

(cosθ ,sinθ )=(16/19,y)

By comparison:

cosθ =16/19

sinθ =(√105)/19

So the exact value of sin θ  and cos θ  is: sinθ =(√105)/19 and cosθ =16/19

If 3x + 7y = 12 and x-y= 1, then what is the value of 5x + 5y?
lilavasa [31]

Answer:

14.

Step-by-step explanation:

3x + 7y = 12

x - y = 1           Multiply this by -3:

-3x + 3y = -3     Add this to equation 1:

0 + 10y = 9

so y = 9/10 = 0.9.

x - 0.9 = 1

x = 1.9.

So 5x + 5y = 5*1.9 + 5*0.9

= 14.

Deanna measured the length of a piece of wood three times. The measurements were 25.67 cm, 25.79 cm, and 25.71 cm. List the meas
Radda [10]

Answer:

25.67 ; 25.71 ; 25.79

Step-by-step explanation:

Give the measurement :

25.67 cm, 25.79 cm, and 25.71 cm.

Arrangement of numbers on a line plot is arranged in ascending order ( lowest to highest)

Hence,

25.67 < 25.71 < 25.79

Therefore they will follow the arrangement :

25.67 ; 25.71 ; 25.79

Please who can help me?
Natasha2012 [34]
Sorry, very late response since I had other matters to attend to.
Question 1:
A: Incorrect; if that was the case, on day 1, the price would be 150. Instead here, according to the graph, on day 1 the price is 30. 

B: Incorrect; the slope, or rate of change, is 30.
[Note: To calculate the slope, we can take two points (I've chosen points (1,30) [1] and (2,60) [2] for you) and use the formula \frac{y^2 - y^1}{x^2 - x^1}.  \frac{60 - 30}{2 - 1} ⇒ \frac{30}{1}. \frac{x}{1} = x, therefore \frac{30}{1} = 30.]

C; Correct; each day the price increases by (+) 30.

D: Incorrect; the line does not show a constant decrease, but instead a constant increase.

Question 2:
A: Most likely this answer choice. The equation seems to be in slope-intercept form on accounting that the equation has mx and b. M has the x directly after it while the b is a number that stands alone. [Note: Numbers that stand alone and without a variable are constants.] B stands for the y-intercept/initial value, or amount started with. 

In short:
Q1: C
Q2: A
