Q8. Look At The Image.

Answers

Answer 1

Answer:

Option B

Step-by-step explanation:

Quadratic equation given in the question is,

[tex]x^2+4x+2=0[/tex]

By comparing this equation with the standard quadratic equation,

[tex]ax^2+bx+x=0[/tex]

[tex]a=1,b=4[/tex] and [tex]c=2[/tex]

By using quadratic formula to get the roots of the given quadratic equation,

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

By substituting the values of a, b and c in the formula,

[tex]x=\frac{-4\pm\sqrt{4^2-4(1)(2)}}{2(1)}[/tex]

[tex]x=\frac{-4\pm\sqrt{16-8}}{2}[/tex]

[tex]x=\frac{-4\pm\sqrt{8}}{2}[/tex]

[tex]x=\frac{-4-\sqrt{8}}{2},\frac{-4+\sqrt{8}}{2}[/tex]

[tex]x=-3.414,-0.5857[/tex]

[tex]x=-3.41,-0.59[/tex]

Therefore, Option B will be the answer.

1a) 4/12, 1b) 3/12, 1c) 12/144
1a) 4, 1b) 3, 1c) 12

Answers

Answer:

4/12 = yellow

3/12 = purple

12/144 = yellow and purple

Step-by-step explanation:

the first two are pretty self explanitory. The last one requires you to multiply the answers of the first two together. Make sure you multiply both the top and the bottom (don't use common denominator here)

Answer:

The answer to this is the 3rd choice which is 1a) 4/12, 1b) 3/12, 1c) 12/144.

Step-by-step explanation:

This is pretty simple. To identify the probability of the yellow marbles, you can find the amount of yellow marbles and the total amount of marbles. You take it as a fraction which would be 4/12.

The total amount of marbles : 3 purple + 5 green + 4 yellow = 12 total marbles

The amount of yellow marbles : 4 yellow

Probability of yellow marbles : 4/12

To identify the probability of the yellow marbles, you can find the amount of purple marbles and the total amount of marbles. You take it as a fraction which would be 3/12.

The total amount of marbles : 3 purple + 5 green + 4 yellow = 12 total marbles

The amount of purple marbles : 3 purple

Probability of purple marbles : 3/12

To identify the probability of both the yellow and purple marbles, you can find the amount of yellow and purple marbles along with the total amount of marbles. Since we know this from the work above, you just need to multiply both probabilities. You take it as a fraction which would be 12/144.

The total amount of marbles : 3 purple + 5 green + 4 yellow = 12 total marbles

The amount of yellow marbles : 4 yellow

The amount of purple marbles : 3 purple

Probability of yellow marbles : 4/12

Probability of purple marbles : 3/12

Probability of both marbles : 12/144

So this question is already perfectly set up. Since the 6 and -6 cancel you’ll be left with 5x + 3x which is 8x and -32 + 48 which is 16. 8x=16. Isolate x to get that x=2. Plug 2 back into one of the equations. 5(2) -6y = -32. Solve for y now. -10-32 equals -42. Divide -42 by -6 to get 7. So the final coordinate where the two equations will intersect is (2,7)

A) The equation is d = 2tB) Independent variable = time; dependent variable = amount of cookies

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

Explanation:

The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.

The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.

The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.

BEC and AED are adjacent angles.

Answers

Answer:

∠BEA = ∠CED = 104° (vertical angles)

∠ABE and ∠CBE are complimentary angles, i.e. ∠ABE + ∠CBE = 90°

∠BEA and ∠AED are supplementary angles. 104 + 76 = 180

Step-by-step explanation:

Vertical angles are opposite angles formed by the intersection of two lines. Vertical angles are congruent to each other.

Complementary angles are angle whose sum add up to 90° while supplementary angles are angles whose sum add up to 180°

Two angles are adjacent if they are placed side by side and share the same vertex.

∠BEA = ∠CED = 104° (vertical angles)

∠ABE and ∠CBE are complimentary angles, i.e. ∠ABE + ∠CBE = 90°

∠BEC and ∠CED are not vertical angles

∠BEA and ∠AED are supplementary angles. 104 + 76 = 180

∠BEA and ∠AED are not adjacent angles

Step-by-step explanation:

Answer:

361 1-ft square tiles.

Step-by-step explanation:

The area of the room is a square. It has the same length on each side.

To find how many square tiles you need to cover the floor of the room you need to find the area.

Squares are easy to find the area of because you only need to multiply both sides by each other.

19x19=361

To multiply easier, you can 19 by 10 which equals 190.

Then you can add.

190+190

100+100=200

90+90=180

200+180=380

380-19=361

O
A

B.
7/50
C.
7/43
D.
1/5

Answers

The probability of blue candy from the jar of total candy 50 is 7/50. Thus, option B is correct.

Probability is defined as the chance of occurrence of events. From, the given data the total number candies in the jar is 50.

Thus, the total number of events (sample space, S) = 50

number of possible outcomes from the event n(S) = 50

number of blue candies in the jar(favourable outcomes) = 7

Probability of taking the blue candies from the jar,

P(A) = no. of. favourable outcomes / number of possible outcomes

        = 7 / 50

The probability of taking blue candy from the jar = 7/50

Thus, the ideal solution is option B.

Answer:

X is about 58.41 degrees

Step-by-step explanation:

For this problem, lets use sine, since we have the opposite angle from x and we have the hypotenuse.

Therefore, with the equation for sine, we would get

sin(x) = 23/27

sin(x) = 0.851

Now, since we're solving for an angle, inverse it by adding a -1 to move over the sin.

x = sin-1 23/27

Last, use a calculator to get the answer.

What is a converging graph?

Convergent definition in mathematics is a property (displayed by certain innumerable series and functions) of approaching a limit more and more explicitly as an argument (variable) of the function increases or decreases or as the number of terms of the series gets increased.

According to the given problem,

Graph 1, Graph 2 and Graph 4 are diverging graphs. We are assuming this because the a divergent sequence doesn't have a limit. Thus, this sequence converges to 0. In many cases, however, a sequence diverges that is, it fails to approach any real number.

Graph 3 has a limit and converges as it approaches 2.

In
group of 100 persons, 72 people can speak
English and 43 can speak French. How many
can speak English Only, How many can speak
French Only and how many can speak both English and French

Answers

Step-by-step explanation:

Let A be the set of people who speak English.    

B be the set of people who speak French.  

A - B be the set of people who speak English and not French.  

B - A be the set of people who speak French and not English.  

A ∩ B be the set of people who speak both French and English.  

Given

n(A) = 72       n(B) = 43       n(A ∪ B) = 100  

Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)  

 = 72 + 43 - 100  

= 72 + 43 - 100  

= 115 - 100  

= 15

Therefore, Number of persons who speak both French and English

= 15  

n(A) = n(A - B) + n(A ∩ B)  

⇒ n(A - B) = n(A) - n(A ∩ B)  

= 72 - 15  

= 57

and n(B - A) = n(B) - n(A ∩ B)  

 = 43 - 15 = 28  

Therefore, Number of people speaking English only = 57  

Number of people speaking French only = 28

Let A be the set of people who speak English.    

B be the set of people who speak French.  

A - B be the set of people who speak English and not French.  

B - A be the set of people who speak French and not English.  

A ∩ B be the set of people who speak both French and English.  

Given

n(A) = 72       n(B) = 43       n(A ∪ B) = 100  

Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)  

= 72 + 43 - 100  

= 72 + 43 - 100  

= 115 - 100  

= 15

Therefore, Number of persons who speak both French and English

= 15  

n(A) = n(A - B) + n(A ∩ B)  

⇒ n(A - B) = n(A) - n(A ∩ B)  

= 72 - 15  

= 57

and n(B - A) = n(B) - n(A ∩ B)  

= 43 - 15 = 28
