Answer:

Divide by 6

Step-by-step explanation:

The reverse or inverse of multiply by 6 is divide by 6.

Answer:

Options A and D.

Step-by-step explanation:

To check the identities we have to check each option given.

A. tan(x - π) = tanx

We take left hand side (L.H.S.) of the equation.

tan(π - x) = tanx [ since we know tan(π ± x) = tanx ]

So L.H.S. = R.H.S.

It's an identity.

B. sin(x + y) + sin(x - y) = 2cosx siny

We take L.H.S. first

sin(x + y) + sin(x - y)

= sinx coxy + siny cosx + sinx cosy - cosx siny

= 2sinx cosy ≠ R.H.S.

Option B is not an identity.

C. cos(x + y) - cos(x - y) = 2cosx cosy

We take L.H.S. of the equation.

cos(x + y) - cos(x - y) = cosx cosy - sinx siny - (cosx cosy + sinx siny)

= -2sinx siny ≠ R.H.S.

Therefore, option C is not an identity.

D. cos(x + y) + cos(x - y) = 2cosx cosy

We take L.H.S. of the equation.

cos(x + y) + cos(x - y) = cosx cosy - sinx siny + cosx cosy + sinx siny

                                  = 2cosx cosy = R.H.S.

Therefore, option D is an identity.

Options A and D are the identities.

ANSWER

B) (m+p,n+r)

The coordinates are :

A(2m,2n)

B(2p,2r)

To find the x-coordinate of the midpoint of AB, we add the x-coordinates of the two points and divide by 2.

[tex]x = \frac{2m + 2p}{2} [/tex]

Factor

[tex]x = \frac{2(m + p)}{2} [/tex]

Simplify:

[tex]x = m + p[/tex]

Similarly, the y-coordinate is

[tex]y = \frac{2n + 2r}{2} [/tex]

[tex]y = \frac{2(n + r)}{2} [/tex]

[tex]y = (n + r)[/tex]

Hence the midpoint is

(m+p,n+r)

Answer:

Option C is correct.

Step-by-step explanation:

Equation 1 |4x − 3|− 5 = 4

Adding +5 on both sides

|4x − 3|− 5 +5 = 4 +5

|4x − 3| = 9

Apply absolute rule:

IuI = a and a>0 then u = a and u = -a

so, 4x-3 = 9 and 4x-3 = -9

Solving

4x = 9+3   and 4x = -9+3

4x = 12      and 4x = -6

x = 12/4     and x = -6/4

x = 3          and x = -3/2 or -1.5

Equation 2 |2x + 3| + 8 = 3

Adding -8 on both sides

|2x + 3| + 8 -8 = 3 -8

|2x + 3|  = -5

Apply absolute rule:

IuI = a and a>0 then u = a and u = -a

But we cannot apply absolute rule because in our case a < 0 i.e -5

So, Equation 2 has no solutions.

Hence Option C The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution is correct.

Answer:

24

Step-by-step explanation:

⇒The question is on probability, to be specific its about counting principal

⇒You need to understand the counting rule where we multiply events together to get the total number of outcomes .

⇒In general  if we have an event t and another event s the total outcome for the events is given by t×s

⇒In this question  you multiply the number of ways we can make the different sandwiches

Given

meat=3 choices

cheese=2 choices

bread=4 choices

Outcomes= 3×2×4=24

The  total number of sandwiches that can be made = 24

There are 24 different sandwiches that can be made with 3 choices of meat, 2 choices of cheese, and 4 choices of bread.

The subject of this question is related to combinatorics, a topic in mathematics. The question asks, 'How many different sandwiches with one meat, one cheese, and one type of bread can be made if there are 3 choices of meat, 2 choices of cheese, and 4 choices of bread?'.

To find the answer, you would use the fundamental principle of counting which states that if there are n ways to do one thing and m ways to do another thing, then there are n * m total ways to perform both actions. In this case, we multiply the number of options together:

Hence, the total number of different sandwiches that can be made is given by 3 (choices of meat) * 2 (choices of cheese) * 4 (choices of bread), which equals 24 different sandwiches.

Domain = All non-negative numbers; Range = All real numbers greater than or equal to 49; (1, 50)

Step-by-step explanation:

Answer:

Domain = all real number greater than or equal to 49

Range=all non- negative numbers

point=(50,1)

Step-by-step explanation:

The graph of q(x)=x-49

domain is the collection of numbers which assign for x in the function q(x)=x-49

therefore domain is the collection pf real number which is greater than or equal to 49 .

Range is the collection of numbers whic is obtained after aasignig value of x in the function q(x)=x-49

hence, range is the collection of non negative numbers which is obtained after putting the value of x in the given function  q(x)=x-49

when we put x=50 in q(x)=x-49 then we obtain 1

hence, the poin is (50,1) on the given graph.

Final answer:

The probability that a given event does not occur in any of the trials when an experiment is repeated n times is calculated using the formula (1 - P(A))^n, where P(A) is the probability of the event occurring in a single trial.

Explanation:

The question is about finding the probability that a given event does not occur in any of the trials when an experiment is repeated n times. Let's denote the probability of the event occurring as P(A) and the probability of the event not occurring as P(~A). The probability that an event does not occur in a single trial is 1 - P(A). Therefore, if the experiment is repeated n times independently, the probability that the event does not occur in any of these trials is given by (1 - P(A))^n. This formula arises from the principle that for independent events, the probability of both events A and B occurring is the product of their individual probabilities, P(A) and P(B). Since each trial is independent, and we are looking for the event not happening across all n trials, we multiply the probability of it not happening in one trial by itself n times.

Answer:

(5, - 9)

Step-by-step explanation:

Given

f(x) = (x - 8)(x - 2) ← in factored form

Find the zeros by equating f(x) to zero, that is

(x - 8)(x - 2) = 0

Equate each factor to zero and solve for x

x - 8 = 0 ⇒ x = 8

x - 2 = 0 ⇒ x = 2

The vertex lies on the axis of symmetry which is located at the midpoint of the zeros, hence

[tex]x_{vertex}[/tex] = [tex]\frac{8+2}{2}[/tex] = 5

Substitute x = 5 into f(x) for corresponding y- coordinate

f(5) = (5 - 8)(5 - 2) = (- 3)(3) = - 9

vertex = (5, - 9)

Answer: (5,-9)

Step-by-step explanation:

Make the multiplication indicated:

[tex]f(x) = x^2-2x-8x+16[/tex]

Add the like terms:

[tex]f(x) = x^2-10x+16[/tex]

Now find the x-coordinate of the vertex with this formula:

[tex]x=\frac{-b}{2a}[/tex]

In this case:

[tex]b=-10\\a=1[/tex]

Then:

[tex]x=\frac{-(-10)}{2(1)}=5[/tex]

Rewrite the expression with [tex]f(x)=y[/tex]

[tex]y = x^2-10x+16[/tex]

Now substitute [tex]x=5[/tex] into the function to find the y-coordinate of the vertex:

[tex]y = (5)^2-10(5)+16[/tex]

[tex]y =-9[/tex]

Therefore, the vertex is:

Answer:

The measure of angle B is 54°. The measure of angle A is 51°. The measure of angle AFE is 47°.

Step-by-step explanation:

According to exterior angle theorem: It a triangle

Exterior angle = Sum of opposite interior angles

In triangle BED,

[tex]\angle AEF=\angle B+\angle D[/tex]

[tex]82=\angle B+28[/tex]

[tex]82-28=\angle B[/tex]

[tex]54=\angle B[/tex]

The measure of angle B is 54°.

In triangle ABC,

[tex]\angle ACD=\angle A+\angle B[/tex]

[tex]105=\angle A+54[/tex]

[tex]105-54=\angle A[/tex]

[tex]51=\angle A[/tex]

The measure of angle A is 51°.

In triangle AEF,

Using angle sum property,

[tex]\angle A+\angle E+\angle AFE=180[/tex]

[tex]51+82+\angle AFE=180[/tex]

[tex]133+\angle AFE=180[/tex]

[tex]\angle AFE=180-133[/tex]

[tex]\angle AFE=47[/tex]

Therefore the measure of angle AFE is 47°.

Answer:

[tex]b = 17[/tex]

Step-by-step explanation:

For this triangle we have to

[tex]a=18.2\\B=62\°\\C=48\°[/tex]

We know that the sum of the internal angles of a triangle is 180 °

So

[tex]A + 62 +48=180\\\\A=180-62-48\\\\A=70\°[/tex]

Now we use the sine theorem to find the length of b:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

Then:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}\\\\b=\frac{sin(B)}{\frac{sin(A)}{a}}\\\\b=a*\frac{sin(B)}{sin(A)}\\\\b=(18.2)\frac{sin(62)}{sin(70)}\\\\b=17[/tex]
