Use the following Product to Sum Identities:

2 sin A · cos B = sin (A + B) + sin (A - B)

2 cos A · cos B = sin (A + B) + sin (A - B)

Given:  cos A + cos B = 1/2      and      sin A + sin B = 1/4  

Proof LHS → RHS

[tex]\text{LHS:}\qquad \qquad \qquad \tan\dfrac{A+B}{2}[/tex]

[tex]\text{Expand:}\qquad \qquad \dfrac{\sin\frac{(A+B)}{2}}{\cos\frac{(A+B)}{2}}[/tex]

john has 42 pieces of candy. if he has 4 bags and two extra pieces determine how many are in each bag.

Answers

Answer:

10

Step-by-step explanation:

42-2=40(since 2 extra)

=>For each bag=40/10=4

A car, initially at rest, travels 20 m in 4 s along a straight line with constant acceleration. The acceleration of the car is: 1. 0.4 m/s 2 2. 9.8 m/s 2 3. 4.9 m/s 2 4. 1.3 m/s 2 5. 2.5 m/s 2

Answers

Answer:

2.5m/s²

Step-by-step explanation:

Using the equation of motion S = ut + 1/2at² where;

S is the distance travelled = 20m

u is the initial velocity = 0m/s (car starts from rest)

a is the acceleration = ?

t is the time taken = 4s

To get the acceleration of the car, we will substitute the given parameters into the given equation.

S = ut + 1/2at²

20 = 0(4)+1/2a(4)²

20 = 0+ a/2*16

20 = 8a

divide both sides by 8

20/8 = 8a/8

20/8 = a

a = 20/8

a = 2.5m/s²

Hence the acceleration of the car is 2.5m/s²


Setting 7/3 equal to which ratio would result in a valid proportion?
9/49
18/42
42/18
49/9

Answers

the answer is 42/18 because if you were to multiply each number by 6 you will get 42/18

To determine which ratio would result in a valid proportion when set equal to StartFraction 7 over 3 EndFraction, we need to find the ratio that is equivalent to StartFraction 7 over 3 EndFraction.

To do this, we can cross-multiply. When we cross-multiply StartFraction 7 over 3 EndFraction and another ratio, the product of the numerator of StartFraction 7 over 3 EndFraction and the denominator of the other ratio should be equal to the product of the denominator of StartFraction 7 over 3 EndFraction and the numerator of the other ratio.

Let's check each option:

1. StartFraction 9 over 49 EndFraction:

7 x 49 = 343

3 x 9 = 27

These values are not equal, so it is not a valid proportion.

2. StartFraction 18 over 42 EndFraction:

7 x 42 = 294

3 x 18 = 54

These values are not equal, so it is not a valid proportion.

3. StartFraction 42 over 18 EndFraction:

7 x 18 = 126

3 x 42 = 126

These values are equal, so it is a valid proportion.

4. StartFraction 49 over 9 EndFraction:

7 x 9 = 63

3 x 49 = 147

These values are not equal, so it is not a valid proportion.

Therefore, the ratio that results in a valid proportion when set equal to StartFraction 7 over 3 EndFraction is StartFraction 42 over 18 EndFraction.

A line segment has (x1, y1) as one endpoint and (xm, ym) as its midpoint. Find the other endpoint (x2, y2) of the line segment in terms of x1, y1, xm, and ym. Use the result to find the coordinates of the endpoint (x2, y2) of each line segment with the given endpoint (x1, y1) and endpoint (xm, ym).


(a)

(x1, y1) = (1, −4), (xm, ym) = (2, −1)

(x2, y2)=


(b)

(x1, y1) = (−9, 19), (xm, ym) = (5, 6)

(x2, y2)=

Answers

Answer: (a) ([tex]x_{2},y_{2}[/tex]) = (3,2)

              (b)  ([tex]x_{2},y_{2}[/tex]) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]

[tex]y_{m}=\frac{y_{1}+y_{2}}{2}[/tex]

Isolating [tex]x_{2}[/tex]:

[tex]2x_{m}=x_{1}+x_{2}[/tex]

[tex]x_{2}=2x_{m}-x_{1}[/tex]

And [tex]y_{2}[/tex]:

[tex]2y_{m}=y_{1}+y_{2}[/tex]

[tex]y_{2}=2y_{m}-y_{1}[/tex]

(a) Replacing values and calculating [tex]x_{2}[/tex]:

[tex]x_{2}=(2*2)-1[/tex]

[tex]x_{2}=3[/tex]

Calculating [tex]y_{2}[/tex]:

[tex]y_{2}=[2*(-1)]-(-4)[/tex]

[tex]y_{2}=2[/tex]

[tex](x_{2},y_{2})=(3,2)[/tex]

(b) [tex]x_{2}=(2*5)-(-9)[/tex]

[tex]x_{2}=19[/tex]

[tex]y_{2}=(2*6)-19[/tex]

Answer:

107 cm

Step-by-step explanation:

To find this you just first add the 26cm three times because thats the length of 3 sides and you get 78 then you multiply 14.5 times 2 for the other two sides that length and you get 29. Next you add 78+29 and you get 107cm

What is the distance, to the nearest whole number, from K (5, 6) to P (1, 1)?

Answers

Answer:

The answer is 6 units

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

K (5, 6) P (1, 1)

The distance from K to P is

[tex] |KP| = \sqrt{ ({5 - 1})^{2} + ({6 - 1})^{2} } \\ = \sqrt{ {4}^{2} + {5}^{2} } \\ = \sqrt{16 + 25} \\ = \sqrt{41} \\ = 6.403124[/tex]

We have the final answer as

6 units to the nearest whole number
