The coordinates of A, B,and C in the diagram are A(p,4), B(6,1), C(9,q). What equation correctly relates p and q?

Answers

I don't see any diagram. So, I'll just wing it.

Value of q:
p, 6, 9 ⇒ there is a difference of 3. The sequence increases by 3. So, it can be assumed that the p is equal to 3. A(p,4) ⇒ A(3,4)

Value of q:
4, 1, q ⇒ there is a difference of 3. The sequence decreases by 3. So, it can be assumed that q is equal to -2. C(9,-2)
 
        p        q
A     3        4     ⇒ 3 + 4 = 7
B     6        1     ⇒ 6 + 1 = 7
C     9       -2    ⇒ 9 + (-2) = 7

Notice that the sequence has an equation of p + q = 7.

Answer:

C

Step-by-step explanation:

p+q=7

Review the graph.What is the magnitude of the vector shown?

5
13
StartRoot 5 EndRoot
StartRoot 13 EndRoot

Answers

The required magnitude of the vector is √13. Option D is correct.

A graph is given, that shows the vector, the magnitude of the vector is to be determined.

What is vertex form?

Vector form is defined as representing any point in space that has both magnitude and direction.  A point k in space is represented as a vector OKi + OKj, which denotes the vector line, OK joining the line from the origin O to the point k. The vector form is used to define a line or a plane in a 3D space.

From the figure,
given vector can be expressed as,
\bar v = 3\bar i+2\bar j
now the magnitude of vactor,
|\bar v| = √(3^2+2^2)\n|\bar v| = √(9+4)\ \n|\bar v| = √(13)\

Thus, the required magnitude of the vector is √13. Option D is correct.

Four people in a room. Each shakes hands with each of the others once. How many handshakes are there? 6
10
12
16
22

Answers

The correct answer is 6.

The clearest way to determine this is by creating a table of possible hand shaking. If we label the people A-D, the following are the ways they can be combined:
AB
AC
AD
BC
BD
CD

There are no other combinations.

There are 6 handshakes betweenfour people in the room.

Further explanation

The probability of an event is defined as the possibility of an event occurring against sample space.

\large { \boxed {P(A) = \frac{\text{Number of Favorable Outcomes to A}}{\text {Total Number of Outcomes}} } }

Permutation ( Arrangement )

Permutation is the number of ways to arrange objects.

\large {\boxed {^nP_r = (n!)/((n - r)!) } }

Combination ( Selection )

Combination is the number of ways to select objects.

\large {\boxed {^nC_r = (n!)/(r! (n - r)!) } }

Let us tackle the problem.

This problem is about Combination.

If there are 4 people in a room , then the number of handshaking between 2 people is analogy as selecting 2 people from 4 people available. We will use combination formula in this problem.

^4C_2 = (4!)/(2! (4-2)!)

^4C_2 = (4!)/(2! 2!)

^4C_2 = (4 * 3 * 2 * 1)/(2 * 1 * 2 * 1)

^4C_2 = ( 24 )/(4)

^4C_2 = \boxed{6}

Use the digits 1,3,4,and 7 to create two whole numbers whose product is estimated to be about 600

Answers

Answer: 34 and 17 are two numbers created from the given digits whose product is estimated to be about 600.

Step-by-step explanation:

Let 34 and 17 are two whole numbers created from the given digits.

Case 1) If we multiply 34 and 17 then 34×17=578 if we rounding up to the nearest hundreds we will get 600.

Case 2) If we rounding up the whole numbers before multiplication as

estimate of 34 to the nearest ten is 30 and 17 to the nearest ten is 20

Then the product becomes 30×20=600.

So by both the ways 34 and 17 can be used for estimated product to be 600.
34 x 17  (round the 2 numbers)
30 x 20
   600

Also, 34 x 17 = 578, which rounds to 600


The answer is 34 and 17

What are the real or imaginary solutions of the polynomial equation? x^3 = 216

Answers

x^3 = 216
this means that
x = 216^1/3
x = 6 (real solution)

x = -3 -3^(3/2)i (imaginary solution)
x = -3 +3^(3/2)i (imaginary solution)
x³ = 216 
∛x³ = ∛216
x = 6
