What is the vertex of the graph of this function? y= -(x+2)(x+4)

You can even get a Brainiest (or whatever its called) plz help.

Scale factor of 2 means green circle is twice the size of blue circle.

If C= πd and 2(d1) = d2, Then the circumference of the image (scaled copy) should be twice the circumference of the object (original circle).

The value of the variable 'x' will be 25. Then the correct option is B.

If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral. And the sum of opposite angles of the quadrilateral is 180 degrees.

Quadrilateral EFGH is inscribed in a circle as shown. ∠F = (4x + 10)°, ∠G = (2x - 5)º, and ∠H = (3x - 5)°.

Angles ∠F and ∠H will be supplementary angles. Then the equation is given as,

∠F + ∠H = 180

4x + 10 + 3x - 5 = 180

7x = 175

x = 25

The value of the variable 'x' will be 25. Then the correct option is B.

Explanation:

If a set has n elements inside it, then it has 2^n different subsets.

Consider a set like {a,b,c}. It has n = 3 elements.

It has 2^n = 2^3 = 8 subsets

Those 8 subsets are...

As you can see, each subset consists of items that are selected from the original set {a,b,c}. We can't have any repeat letters.

In that list, items 2 through 4 represent subsets with exactly two things inside it. Items 5 through 7 are known as singletons as they only have one item inside each set. The empty set can be written with the symbol [tex]\varnothing[/tex] or you could have a pair of braces with nothing inside them. The empty set is a subset of any set.

--------------

Note how I included {a,b,c} as a subset. Any set is a subset of itself.

A proper subset will ignore the original set and only look at smaller subsets. If we say B is a proper subset of A, then set B will have fewer items compared to set A. Without the "proper" in there, it's possible that A = B.

So all we've done really is kick out one set which drops 2^n to (2^n)-1 when counting the number of proper subsets. I'm using parenthesis to indicate the "-1" is not part of the exponent. If you wrote this on your paper, then you would likely write [tex]2^{n} - 1[/tex]

--------------

For this problem, n = 11

This means there are 2^n = 2^11 = 2048 subsets and (2^n)-1 = 2048-1 = 2047 proper subsets.

The number of subset of a set containing 11 elements is 2,048

And, number of proper subset of a set containing 11 element is 2,047.

Here,

A set containing 11 elements.

We have to find number of Subsets and number of Proper subsets.

What is Proper subset of a set?

Set A is considered to be a proper subset of Set B if Set B contains at least one element that is not present in Set A.

Now,

Let a set containing n elements.

then, Number of subsets = [tex]2^{n}[/tex]

And, Number of proper subsets = [tex]2^{n} -1[/tex]

Hence,

A set containing 11 elements.

Number of subsets = [tex]2^{11} = 2,048[/tex]

And, Number of proper subsets = [tex]2^{11} -1 = 2,048 - 1 = 2,047[/tex]

Hence, The number of subset of a set containing 11 elements is 2,048

And, number of proper subset of a set containing 11 element is 2,047.

Answer:

Step-by-step explanation:

Answer:

The ratio 1:3:5 by doubling each number is the same as 2:6:10 and the big one 10 is 10/(2+6+10) = 10/18 of the total, so multiplying top and bottom by 10 gives 100/180, so the biggest angle is 100° since the sum of all angles must be 180°.

Answer:

the answer is 1/2...............

The fraction 1/2 which is equivalent to 4/8 is greater than 1/2.

Given fraction to compare 1/8 or 1/2.

To compare the fraction, the denominator of both fraction should be same.

So, to make denominator same take the LCM of 8 and 2 as

8 = 2 x 2 x 2

2 = 2 x 1

Then, the LCM( 8, 2) = 8.

Now, the fraction can be written as

1/8 or 1/2 x 4/4 =  4/8.

Therefore, the fraction 1/2 is greater than 1/8.

Answer:

[tex]Opposite =- \frac{4}{5}[/tex]

Step-by-step explanation:

Given

[tex]Number = \frac{4}{5}[/tex]

Required

Determine its opposite

To get the opposite of a number, we simply subtract it from 0.

So, we have:

[tex]Opposite =0 - \frac{4}{5}[/tex]

[tex]Opposite =- \frac{4}{5}[/tex]

Hence, the opposite is -4/5

Answer:

a) 0.5 = 50% probability that an NPN transistor will be selected.

b) 0.3333 = 33.33% probability that it came from the cabinet that contains both types

c) 66.67% probability that it comes from the cabinet that contains only NPN transistors

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

a) What is the probability that an NPN transistor will be selected?

1/3 probability that the first cabinet is chosen. This cabinet has two transistors, both of which are NPN, so 100% probability of selecting a NPN transistor.

1/3 probability that the second cabinet is chosen. This cabinet has two transistors, both of which are PNP, so 0% probability of selecting a NPN transistor.

1/3 probability that the second cabinet is chosen. This cabinet has two transistors, one of which is NPN, so 50% probability of selecting a NPN transistor.

So

[tex]p = \frac{1}{3}*1 + \frac{1}{3}*0 + \frac{1}{3}*0.5 = \frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = 0.5[/tex]

0.5 = 50% probability that an NPN transistor will be selected.

b) Given that the hobbyist selects an NPN transistor, what is the probability that it came from the cabinet that contains both types?

Here we use the conditional probability formula.

Event A: NPN transistor

Event B: From the third cabinet.

50% probability that an NPN transistor will be selected, so [tex]P(A) = 0.5[/tex].

1/6 probability that it is from the third cabinet and NPN, so [tex]P(A \cap B) = \frac{1}{6}[/tex]

The desired probability is:

[tex]P(B|A) = \frac{\frac{1}{6}}{0.5} = 0.3333[/tex]

0.3333 = 33.33% probability that it came from the cabinet that contains both types.

c) Given that an NPN transistor is selected what is the probability that it comes from the cabinet that contains only NPN transistors?

Either it comes from the cabinet with only NPN transistors, or it comes from the cabinet with both types of transistors. The sum of the probabilities of these outcomes is 100%. So

x + 33.33 = 100

x = 66.67

66.67% probability that it comes from the cabinet that contains only NPN transistors

Answer:

greater than or equal

Step-by-step explanation:

Answer:  To establish the strength of a linear association, first compute the correlation coefficient between the variables involved. The, examine the absolute value of the coefficient. A strong relationship has an absolute value of close to 1 (or approaching 1) while a weak relationship has an absolute value close to 0 (or approaching zero).

The data points will be clustered more tightly around the trend line if there is a weak linear association and less tightly if there is a strong one.

[tex]B' = (-6,-8)[/tex]

Step-by-step explanation:

Given

[tex]Point\ B = (-6,0)[/tex]

Required

Plot a new point that is 8 units down and also has the same x coordinate

Represent the new point with B'

In [tex]Point\ B = (-6,0)[/tex]

[tex]x = -6[/tex] and [tex]y = 0[/tex]

This means that B' has an x coordinate of -6

Next, is to determine the y coordinate

If a point (x,y) is translated b units down, the new point is (x, y - b)

In this case:

The y coordinate of B is 0 and b = 8. So, the new y coordinate is: 0 - 8 = -8

So, we have:

[tex]B' = (-6,-8)[/tex]
