Step-by-step explanation:

This can be solved using both sine and cosine rule.

1st method:

[tex]\sf sin(x) = \dfrac{opposite}{hypotenuse}[/tex]

[tex]\sf sin(60) = \dfrac{long \ leg}{12}[/tex]

[tex]\sf long \ leg= 12sin(60)[/tex]

[tex]\sf long \ leg= 6\sqrt{3}[/tex]

2nd method:

[tex]\sf cos(x) = \dfrac{adjacent}{hypotenuse}[/tex]

[tex]\sf cos(30) = \dfrac{long \ leg}{12}[/tex]

[tex]\sf long \ leg= 12cos(30)[/tex]

Answer:

Answer: ∠1 = 109°    ∠2 = 71°

Step-by-step explanation:

If the two angles form a linear pair, then their sum is 180°

 ∠1      +     ∠2     = 180°

(5x + 9) + (3x + 11) = 180

             8x + 20  = 180

             8x          = 160

               x          = 20

∠1 = 5x + 9

   = 5(20) + 9

   = 100   + 9

   = 109

∠2 = 3x + 11

    = 3(20) + 11

    =    60  + 11

    =         71

 CHECK:

The will meet after 2.5 hour.

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

let say they will meet after time t.

distance covered by first boat = velocity of boat × time= 8.5t

distance covered by second boat= 5.5t

distance between both boats = 35km.

by equating both the distance

35km = 8.5t+5.5t

35km = 14t

t= 35÷14 =2.5 hour= 9020.618 seconds.

Using the simple interests, we can say that:

Amanda borrowed $4500 from her parents.Amanda borrowed $500 from the credit union.In the question, we are given that Amanda borrowed $5000 from two sources: her parents and a credit union. Her parents charged 5% simple interest and the credit union charged 6% simple interest.We are asked to calculate how much did she borrow from her parents, and how much did she borrow from the credit union, if after 1 year, she paid $255 in interest.We assume that Amanda borrows $x from her parents.Then we know that she would have borrowed $(5000 - x) from the credit union as the total borrowed amount was $5000.We know that the simple interest (S.I.) on $P, at the rate of r%, for a period of t years, is calculated as S.I. = Prt/100.Thus, for the amount she borrowed from her parents, the simple interest is, S.I. = (x)(5)(1)/100 = x/20.For the amount she borrowed from the credit union, the simple interest is,S.I. = (5000 - x)(6)(1)/100 = (30000 - 6x)/100 = 300 - 3x/50.Thus, the total interest Amanda needs to pay is x/20 + 300 - 3x/50 = 300 - x/100.But, we are given that the total interest Amanda pays is $255.Thus, we can write that 255 = 300 - x/100,or, x/100 = 300 - 255,or, x/100 = 45,or, x = 4500.Thus, the amount Amanda borrows from her parents = $4500.The amount she borrows from the credit union is $(5000 - 4500) = $500.Thus, Using simple interests, we can say that:Amanda borrowed $4500 from her parents.Amanda borrowed $500 from the credit union.

Step-by-step explanation:

Answer: The answer is C.

Step-by-step explanation:

Answer:

m<1=75 degree m<2=105degree

m<3=75 degree m<4=105 degree

Answer:

m∠1 = 75°

m∠2 = 105°

m∠3 = 75°

m∠4 = 105°

Step-by-step explanation:

Angles on a straight line sum to 180°

⇒ m∠1 + m∠2 = 180°

Given:

⇒ m∠2 - m∠1 + m∠1 = 30° + m∠1

⇒ m∠2 = 30° + m∠1

Substitute the found expression for m∠2 into the first equation and solve for m∠1:

⇒ m∠1 + m∠2 = 180°

⇒ m∠1 + 30° + m∠1 = 180°

⇒ m∠1 + 30° + m∠1  - 30° = 180° - 30°

⇒ m∠1 + m∠1 = 150°

⇒ m∠1 = 150° ÷ 2

⇒ m∠1 = 75°

As angles on a straight line sum to 180°, subtract m∠1 from 180° to find m∠2:

⇒ m∠2 = 180° - m∠1

⇒ m∠2 = 180° - 75°

⇒ m∠2 = 105°

Vertical Angles Theorem:  When two straight lines intersect, the opposite vertical angles are the same (congruent).

⇒ m∠3 = m∠1 = 75°

⇒ m∠4 = m∠2 = 105°

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

From the graph, the function has four different definitions, in intervals, A, B, C and D.

From the axis of the graph, we have that:

1. The x-axis represents the time in hours.

2. The y-axis represents the distance in miles.

Considering that the graph has points (0,0) and (4,30), we have that:

3. The person traveled 30 miles in those 4 hours.

The velocity is given by distance divided by time, hence:

30/4 = 7.5.

4. The person traveled at a rate of 7.5 miles per hour in Section A.

In Section B, the person remains at the same position, hence:

5. In section B, the person remained stopped 30 miles from her starting point for 2 hours.

The distance was of 0, hence:

6. The velocity for Section B was of 0 miles per hour.

In Section C, from the y-axis of the graph, the distance traveled was:

60 - 30 = 30 miles.

7. The person traveled 30 miles in Section C.

For Section D, the person traveled 60 miles in 10 - 7 = 3 hours, hence:

60/3 = 20.

8. The speed in Section D was of 20 miles per hour.

10. The farthest distance traveled was of 60 miles in Section D.

In Section C, the person traveled 30 miles in one hour = 30 miles per hour, hence:

9. The person was moving at the highest speed in Section C, at a rate of 30 miles per hour.

For item 11, a situation that can be modeled is:

A person had an appointment 30 miles away from their home, and due to slow traffic had to leave early. Then the appointment lasted 2 hours, then the person went to another place 30 miles away to do something then came back home.

Domain of f + g ( x) = R and f - g ( x) = R

Given :

F(x) = 2x^2 + 8  and g(x) = x-3

From this, we get to know that f(x) and g(x) assume real values for all values of x.

Hence, domain (f)= Real(R) and domain (g)= real ( R ) .

Therefore D (f) and D(g) are Real Number

Now,

A >   (f + g ) : R ----> R is given by (f + g) (x)

       = f(x) + g(x) = 2x^2 + 8 + x- 3

                             = 2x^2  + x + 5

Hence, domain ( f + g ) = Real ( R )

B >    (f – g) : R---> R is given by ( f-g ) (x)

= f(x) – g(x)  = 2x^2 + 8 – ( x – 3)

                    = 2x^2 -x + 11
