Find the value of each variable using sine and cosine. Round your answer to the nearest tenth.

Answers

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

copy and paste the above on to your computer for future reference

n= Hyp

m= adj

8 = Opp

∠=50°

sin(50) = 8/n

n = 8/sin(50)

n = 10.44325

n= 10.4 ( to nearest 10th)

tan(50) = 8 / m

m = 8 / tan(50)

m = 6.712797

m = 6.7 ( to nearest 10th )

Where is the blue dot located on the number line

Answers

-19 it goes back by threes so count back and you get negative 19

Answer: -19

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

Explanation:

Use the midpoint formula to find the midpoint of -10 and -4

A = -10 = left endpoint

B = -4 = right endpoint

C = midpoint of A and B

C = (A+B)/2

C = (-10+(-4))/2

C = -14/2

C = -7

The value -7 is exactly midway between -10 and -4, so that's the missing tickmark between those values. Consequently, it also means each gap is 3 units wide (i.e., distance from -10 to -7 is 3 units).

Start at -10 and subtract 3 to move to the left by that amount. Do this three times to follow this pattern:

move from -10 to -13move from -13 to -16move from -16 to -19

The blue dot is located at -19

Answer:

3.5

Step-by-step explanation:

add the two 5 and then subtract the perimeter which is 24 , so 24-10 is 14 then divide it by 4 for the missing sides and u get 3.5

The value of x in the given hexagon is 3.5 m.

What is the Perimeter of Hexagon?

Perimeter of Hexagon is equal to sum of all sides.

Here, Two sides are 5 m long

and remains 4 sides have length x m.

Perimeter = Sum of all sides

24 = 2 X 5 + 4x

24 = 10 + 4x

4x = 24 -10

4x = 14

x = 14/4

x = 3.5 m

Thus, the value of x in the given hexagon is 3.5 m.

How do you find the value for x?
Find the value of x ?

Answers

Answer:

x = 27

Step-by-step explanation:

Both angles together form 180 degree.

Set your formula up as

180 = (5x+2) + (x + 16)

180 = 5x + 2 + x + 16

180 = 6x + 18

180 - 18 = 6x

162 = 6x

162/6 = x

27 = x

Answer:

27°

Step-by-step explanation:

They are in a straight line , therefore ,

> 5x + 2 + x + 16 = 180

> 6x + 18 = 180

> 6x = 180 - 18

> 6x = 162

> x = 27

Hence the required answer is 27°

BRAINLIEST FOR CORRECT ANSWER!! Kenny leaves home and walks 10 blocks east and 24 blocks north to get to the movie theater. How far is the movie theater from Kenny’s home if he were to take a direct path?

Answers

Answer:

8.568cm

Step-by-step explanation:

IF Kenny leaves home and walks 10 blocks east and 24 blocks north to get to the movie theater, his distance from home to the theatre is gotten using the pythagoras theorem as shown;

d² = 23² + 10²

d² = 529 + 100

d² = 629

d = √629

d = 8.568

Hence the required distance is 8.568cm

50% of students change their major area of study after their first year in a program. A random sample of 100 students in the College of Business revealed that 48 had changed their major area of study after their first year of the program. Has there been a significant decrease in the proportion of students who change their major after the first year in this program

Answers

Answer:

Hence, since z ( - 0.4 ) is greater than ( -1.65 );

we reject H₀, Null hypothesis,

Therefore, There is no evidence that there has been a significance decrease in the proportion of students who change their major after the first year in the program.

Step-by-step explanation:

Given the data in the question;

Let p = 50% = 0.5

Hypothesis;

Null hypothesis H₀ : p ≥ 0.5

Alternative hypothesis H₁ : p < 0.5

x = 48

sample size n = 100

sample proportion p" = x / n = 48 / 100 = 0.48

significance value = 0.5

[tex]Z_\alpha[/tex] = -1.65

Test Statistics;

z = (p" - p) / √( p( 1 - p ) / n )

we substitute

z = (0.48 - 0.5) / √( 0.5( 1 - 0.5 ) / 100)

z = -0.02 / √( 0.25 / 100 )

z = -0.02 / √0.0025

z = -0.02 / 0.05

z = -0.4

Hence, since z ( - 0.4 ) is greater than ( -1.65 );

we reject H₀, Null hypothesis,

Therefore, There is no evidence that there has been a significance decrease in the proportion of students who change their major after the first year in the program
