Step-by-step explanation:

Answer:

7

Step-by-step explanation:

The greatest common factor is the largest number that goes into both numbers. In this case, that is 7.

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

Step-by-step explanation:

The graph of the function y = (1/3)ˣ+4 is vertically shifted graph of the function y = (1/3)ˣ

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.

Given is a function y = (1/3)ˣ+4, we need to compare the graph of this function to the graph of the function y = (1/3)ˣ

We know that,

In vertical shifting, adding a constant to a function will shift its graph vertically, adding a positive constant c will shift the graph upward c units, while adding a negative constant c will shift it downward c units.

Here, we can see, in y = (1/3)ˣ+4, constant 4 is added, that mean the graph of the function y = (1/3)ˣ is vertically shifted upward 4 units.

Hence, the graph of the function y = (1/3)ˣ+4 is vertically shifted graph of the function y = (1/3)ˣ

A graph of the cube root function g(x) = 1/2x³ is shown in the image below.

In Geometry, a dilation is a type of transformation which typically transforms the dimension (size) or side lengths of a geometric object, without affecting its shape.

This ultimately implies that, the dimension (size) or side lengths of the dilated geometric object would be stretched or shrunk depending on the scale factor that is applied.

When the parent cube root function f(x) = x³ is vertically shrunk by a scale factor of 1/2, the transformed function g(x) is given by;

g(x) = kf(x)

g(x) = 1/2f(x)

g(x) = 1/2x³.

Using the cosine ratio, the distance between Dimitri and Sarah is calculated as approximately 12.4 m.

The cosine ratio is a trigonometric ratio that represents the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle. It is calculated by dividing the length of the adjacent side by the length of the hypotenuse.

Using the cosine ratio, we have:

Reference angle (∅) = 72 degrees

Hypotenuse length = 40 m

Adjacent length = distance between Dimitri and Sarah = x

Plug in the values:

cos 72 = x/40

x = cos 72 * 40

x ≈ 12.4 [to one decimal place]

Answer:

The object will hit the ground after 9 seconds.

Step-by-step explanation:

We are given the function:

\(\displaystyle h(t) = -16t^2 + v_0t + h_0\)

Where h is the height of the object after time t, v₀ is the initial velocity, and h₀ is the initial height.

An object is thrown upwards from a height of 720 feet and an initial velocity of 64ft/s. We can to determine how long it will take for the object to reach the ground.

Hence, h₀ = 720 and v₀ = 64. Substitute:

\(\displaystyle h(t) = -16t^2+64t+720\)

When the object reaches the ground, its height h above the ground will be zero. In other words:

\(\displaystyle 0 = -16t^2 + 64t + 720\)

Solve for t:

\(\displaystyle \begin{aligned} -16t^2 + 64t + 720 &= 0 \\ \\ t^2 - 4t-45 & = 0 \\ \\ (t-9)(t+5) & = 0 \\ \\ t &= -5 \text{ or } t = 9\end{aligned}\)

Since time cannot be negative, we can ignore the first solution.

In conclusion, the object will hit the ground after 9 seconds.

Answer:

No, the zeros of the function are at x = 3/4 and x = –2

Step-by-step explanation:

the equation

4x² + 5x – 6 = 0

(note: since there is a coefficient of x² we need to multiply it to the last term(6))

4x² + 5x – 24 = 0

the factors are :- 8x and – 3x

4x² + 8x – 3x – 6 = 0

4x( x + 2) –3( x + 2) = 0

( 4x – 3)( x + 2) = 0

the zeros will be

4x – 3 = 0

4x = 3

\(x = \frac{3}{4} \)

x + 2 = 0

x = – 2

the zeros are x= 3/4 or –2

(a) The conditional PMF P X∣B (x) of X given the event B={X<4} can be calculated using the formula

P(X=x|B) = P(X=x and B)/P(B).

Since the event B={X<4} includes the events X=1, X=2, and X=3, we can calculate P(B) as the sum of the probabilities of these events:

P(B) = P(X=1) + P(X=2) + P(X=3) = (1/4) + (3/4)(1/4) + (3/4)^2(1/4) = 13/16.

Therefore, the conditional PMF P X∣B (x) is given by:

P(X=1|B) = P(X=1 and B)/P(B) = (1/4)/(13/16) = 4/13
P(X=2|B) = P(X=2 and B)/P(B) = (3/4)(1/4)/(13/16) = 3/13
P(X=3|B) = P(X=3 and B)/P(B) = (3/4)^2(1/4)/(13/16) = 6/13

(b) The probability that your favourite character is eliminated in one of the first two episodes given the spoiler is P(X=1|B) + P(X=2|B) = 4/13 + 3/13 = 7/13.

(c) The expected value of X conditioned on the event B can be calculated using the formula E[X|B] = sum(x*P(X=x|B)) for all x in the support of X. Therefore, E[X|B] = 1*(4/13) + 2*(3/13) + 3*(6/13) = 20/13.

(d) The conditional PMF P X∣C (x) of X given the event C={X>2} can be calculated using the formula P(X=x|C) = P(X=x and C)/P(C). Since the event C={X>2} includes the events X=3, X=4, ..., we can calculate P(C) as the sum of the probabilities of these events: P(C) = P(X=3) + P(X=4) + ... = (3/4)^2(1/4) + (3/4)^3(1/4) + ... = (3/4)^2/(1-(3/4)) = 12/16. Therefore, the conditional PMF P X∣C (x) is given by:

P(X=3|C) = P(X=3 and C)/P(C) = (3/4)^2(1/4)/(12/16) = 1/3
P(X=4|C) = P(X=4 and C)/P(C) = (3/4)^3(1/4)/(12/16) = 1/4
...

(e) The conditional PMF P Y∣C (y) of Y given the event C={X>2} can be obtained by shifting the conditional PMF P X∣C (x) of X given the event C={X>2} by 2 units to the left. Therefore, P Y∣C (y) = P X∣C (y+2) for all y in support of Y. This conditional PMF belongs to the family of geometric random variables with parameter 1/4.

(f) The conditional mean E[X|C] can be calculated using the formula E[X|C] = sum(x*P(X=x|C)) for all x in the support of X. Since the conditional PMF P X∣C (x) is a geometric distribution with parameter 1/4 shifted by 2 units to the right, we can use the formula E[X|C] = 2 + 1/(1/4) = 6.

The circumferance of a circle with radius of 6cm is 37.68cm

To find:

Circumferance of a circle

Given:

Radius of circle is 6cm

Solution:

Circumference is similar to perimeter as it is the total length required to draw a circle.

Let c be the perimeter.

c = 2πr

or

c = πd

This depends on knowing the radius (r) or diameter (d).

For example, let's calculate it manually.

If r = 6 cm, the circumference in π is c = 2π(6) = 12π cm.

When expressed numerically, it is 37.7 cm after the decimal point is rounded off.

Point Q:  ( 6, 6)

Step-by-step explanation:

    (10, 10)

- 2 (8, 8)

      ( 6, 6)

Answer:

Point Q is at (6, 6).

Step-by-step explanation:

Segment QR has a midpoint M at (8, 8).

Point R is at (10, 10), and we want to determine the location of Point Q.

First, recall that the midpoint is given by the formula:

\(\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)\)

We will let R(10, 10) be (x₁, y₁). We are also given that M is at (8, 8). Therefore:

\(\displaystyle (8, 8)=\Big(\frac{10+x}{2}, \frac{10+y}{2}\Big)\)

This gives us two cases:

\(\displaystyle \frac{10+x}{2}=8\text{ and } \frac{10+y}{2}=8\)

Solve for each case. Multiply both sides by 2:

\(10+x=16\text{ and } 10+y=16\)

And we can subtract 10 from both sides:

\(x=6\text{ and } y=6\)

Therefore, Point Q is at (6, 6).

Answer:

RQ / SQ

Step-by-step explanation:

We see in the figure that angles O and R are congruent, which is what the ) symbol by the two angles indicates.

We see that the first ratio starts with OQ and ends with PQ to give us OQ/PQ.  Since R and O are congruent, the only ratio that would make the statement true is RQ/SQ.

In relation to the angle L of the right triangle the sides are as follows:

A right angle triangle is a triangle that has one of its angles as 90 degrees.  The sides of a right angle triangle can be named according to the position of the angles in the right angle triangle.

The sides of a right triangle can also be solved by using Pythagoras's theorem or trigonometric ratios.

Let's identify the sides  j,  k, and I in relation to angle L in terms of opposite, adjacent, and hypotenuse.

Therefore,

The hypotenuse side is the longest side of a right triangle.
