Step-by-step explanation:

the max. value is when the smaller set (A) is completely contained in the larger set (B).

then n(A n B) is n(A) = 50.

the set intersection between A and B cannot get bigger than that. or A gets bigger ...

after all, the intersection means it is a set of all elements that exist in BOTH sets.

but then there must be other elements besides A and B in the universal set too, because n(universal set) = 96, and n(A u B) would be only 60.

the min. value could be the empty set or 0. but because n(universal set) = 96, and n(A) + n(B) = 110 and larger than 96, it means that there have to be some shared elements. at least 110 - 96 = 14 elements.

in this case there cannot be other elements in the universal set than A and B. and n(universal set) = n(AuB) = 96.

Option C. The mean is less than the median in the distribution of the scores.

The equation of the line is y = 2/3x + 4

The points on the line are given as:

(zero, four) and (negative six, zero).

Rewrite the points properly as

(0, 4) and (-6, 0)

The slope of the line is calculated using:

m =(y2 - y1)/(x2 - x1)

Substitute the known values in the above equation

m = (0 - 4)/(-6 - 0)

Evaluate

m = 2/3

The equation of the line is then calculated as:

y = mx + b

This gives

y = 2/3x + b

So, we have:

The end behavior of the given polynomial is that as x → -∞ or  x → ∞, then, f(x) → 5

We are given the polynomial;

f(x) = 5x/(x - 25)

Now, we want to find the limits as x → ±∞. Let us rearrange the given polynomial to get; f(x) = 5/(1 - (25/x))

Thus, applying limits we have;'

lim x → ±∞ [5/(1 - (25/x))]

From algebraic limit laws we know that;

If f(x) = k, then;

lim x → +∞ [f(x)] = k

Also, lim x → -∞ [f(x)] = k

Thus, applying limits at infinity to our polynomial gives;

lim x → ±∞ [5/(1 - (25/x))] = 5/(1 - 0) = 5

This is because lim x → ∞ for 1/x is 0.

Thus, f(x) has horizontal asymptotes at y = 5

Thus, we conclude that the end behavior is that as x → -∞ or  x → ∞, then, f(x) → 5

Given : Chords A C and B D intersect at point E.  Length of Different segments is given in terms of x

To find :  Length of chord BD

Solution:

Chords A C and B D intersect at point E.

=> AE * CE   = BE * DE

AE = x

CE = x + 12

BE = x + 2

D = x + 5

=> x(x + 12) = (x + 2)(x + 5)

=> x² + 12x  = x²  + 7x + 10

=> 5x = 10

=> x = 2

BD = BE + DE

= x + 2 + x + 5

= 2x + 7

putting x = 2

=> BD = 2 (2) + 7

Applying the intersecting chord theorem, the length of segment CE in is: 2.5 units.

In geometry, the intersecting chords theorem is the theorem that defines the relation of the four line segments formed when two chords of a circle intersect each other at a point in the circle.

According to the intersecting chords theorem, the products of the lengths of the line segments that are formed on each chord are congruent or equal to each other.

In the diagram given, we have chords AC and BD intersecting at point E to form the following line segments:

BE = BD - DE = 7 - 2 = 5 units

DE = 2 units

AE = 4 units

CE = ?

Based on the intersecting chord theorem, we have:

(BE)(DE) = (AE)(CE)

Plug in the values

(5)(2) = (4)(CE)

10 = 4(CE)

Divide both sides by 4

10/4 = 4(CE)/4

2.5 = CE

CE = 2.5 units

Thus, applying the intersecting chord theorem, the length of segment CE in the circle given is: 2.5 units.

Answer:Triangle A = 7.5 Triangle B= 15 Area=22.5

Step-by-step explanation:

So first we have to get the area of Triangle A. This means we have to find the height and base of it. The base is 5 and the height is 3 as you can see in the picture. So 5x3 equals 15, but because it's a triangle we have to divide by 1/2, which makes 7.5. So the area for Triangle A is 7.5.

Now we have to find the area for Triangle B. The height is 3 and the base is 10. So like we did with Triangle A we have to multiply and then divide by 1/2. Which makes 15.

Now that you have both areas you just have to add them together. Which makes 22.5.

So 22.5 is the answer. Give brainilest if you can!

The lengths of each side of the triangle LMN are, LM = 4 units, MN = 3.606 units, and NL = 2.236 units.

The lengths of each side of the triangle L'M'N' are, L'M' = 4 units, M'N' = 3.606 units, and N'L' = 2.236 units.

We can conclude that all corresponding sides are equal, and the two triangles are congruent.

All angles must be congruent, as the image L'M'N' has been parallelly translated from the preimage LMN.

The coordinates of the image are L' (-4, 1), M' (-4, 5), and N' (-2, 2). The length of each side of the triangle LMN:

LM = √((2 - 2)² + (-6 - (-2))²),

or, LM = √((0² + (-4)²),

or, LM = √16 = 4 units.

MN = √((2 - 4)² + (-2 - (-5))²),

or, MN = √((-2)² + (3)²),

or, MN = √(4 + 9) = √13 = 3.606 units.

NL = √((4 - 2)² + (-5 - (-6))²),

or, NL = √((2)² + (1)²)

or, NL = √(4 + 1) = √5 units = 2.236 units.

The length of each side of the triangle L'M'N':

L'M' = √((-4 - (-4))² + (5 - 1)²),

or, L'M' = √((0² + (4)²),

or, L'M' = √16 = 4 units.

M'N' = √((-4 - (-2))² + (5 - 2)²),

or, M'N' = √((-2)² + (3)²),

or, M'N' = √(4 + 9) = √13 = 3.606 units.

N'L' = √((-4 - (-2))² + (1 - 2))²),

or, N'L' = √((2)² + (1)²)

or, N'L' = √(4 + 1) = √5 units = 2.236 units.

Now, since LM = L'M', MN = M'N', and NL = N'L', that, is all the corresponding sides are equal, we can conclude that all corresponding sides are equal, and the two triangles are congruent.

Since the triangles are congruent, the image L'M'N' has been parallelly translated from the preimage LMN.

Thus, all angles must be congruent, as the image L'M'N' has been parallelly translated from the preimage LMN.

Every point moves the same amount and in the same direction throughout a translation. As a result of the picture being identical in size and shape to the preimage, a translation is referred to as a rigid transformation or isometry.

The y-intercept of the line is (0,7).

Given the pairs of a line in the coordinate plane are (x, y) (-72,25), (-54,13) and (-36,11).

First we will find the slope of the linear equation

The formula for calculating the slope between two points is equal to

m = (y₂-y₁) / (x₂-x₁)

take points (-54,13) and (-36.,11)

by substituting the values ​​in the above formula, we get

m = (11-13) / (- 36 - (- 54))

m = -2 / 18

m = -1 / 9

Now, we will find the equation for the line in point-slope form

y-y₁ = m (x-x₁)

we have m = -1 / 9 and (x₁, y₁) = (- 36.11)

Further, substitute the values ​​in the above equation, we get

y-11 = (- 1/9) (x + 36) ..... (1)

Convert the equation to the form of a slope intercept

y = mx + b

isolate the variable y in equation (1), we get

y-11 = (- x / 9) -4

y = (- x / 9) - 4 + 11

y = (- x / 9) +7

Here, b=7

Hence, the y-intercept of the line for the pairs of lines in the coordinate plane(x,y) is (-72,25), (-54,13) and (-36,11) is the point (0,7).

The equation of the line PQ is given as:

3x - y - 2 = 0

The coordinates of the QR are given as:

(0, -2) and (6, -4)

Make y the subject in 3x - y - 2 = 0

y = 3x - 2

The slope of the above line is

m1 = 3

Next, we calculate the slope (m2) of points Q and R.

So, we have:

m2 = (y2- y1)/(x2 - x1)

This gives

m2 = (-4 + 2)/(6 - 0)

Evaluate

m2 = -1/3

The slopes of perpendicular lines are opposite reciprocals.

m1 = 3 and m2 = -1/3 are opposite reciprocals.

This means the lines PQ and QR are perpendicular lines.

The age of Tommy is currently 40-years old

According to the statement

we have given that the tommy is five times as old as bianca and in eight years, tommy will only be three times as old as bianca.

And we have to find the present age of the tommy.

So, This is a question involving the ratio of ages.

Let the ages of Tommy and Bianca in the present be T and B respectively.

STEP 1: Let:

T = 5B

T + 8 = 3 (B+8)

Then

STEP 2: We can substitute T with 5B since the two variables are equal, to create:

5B + 8 = 3 (B + 8)

Then

STEP 3: Finally, we can expand and solve:

5B + 8 = 3B + 24

2B = 16

B = 8

T = 5B = 5 x 8 = 40

T = 40

Therefore, The age of Tommy is currently 40-years old
