Given that P = (2, 9) and Q = (4, 14), find the component form and magnitude of vector PQ . (1 point) <2, 5>, square root of twenty nine <-2, -5>, 29 <2, 5>, 29 <-2, -5>, square root of twenty nine
Given:
The two endpoints of a vector are P = (2, 9) and Q = (4, 14).
To find:
The component form and magnitude of vector PQ .
Solution:
A vector is defined as
[tex]v=\left<x_2-x_1,y_2-y_1\right>[/tex]
Where, [tex](x_1,y_1)[/tex] is the initial point and [tex](x_2,y_2)[/tex] is the terminal point.
Two endpoints of a vector are P = (2, 9) and Q = (4, 14). So, the vector PQ is
[tex]\overrightarrow{PQ}=\left<4-2,14-9\right>[/tex]
[tex]\overrightarrow{PQ}=\left<2,5\right>[/tex]
Component form of vector PQ is [tex]\left<2,5\right>[/tex].
The magnitude of a vector [tex]v=\left<a,b\right>[/tex] is
[tex]|\vec{v}|=\sqrt{a^2+b^2}[/tex]
The magnitude of vector PQ is:
[tex]|\overrightarrow{PQ}|=\sqrt{2^2+5^2}[/tex]
[tex]|\overrightarrow{PQ}|=\sqrt{4+25}[/tex]
[tex]|\overrightarrow{PQ}|=\sqrt{29}[/tex]
Therefore, the correct option is A.
Fathers age is twice his daughter age but 16 years ago fathers age was 4 times his daughters age . Calculate their ages
Answer:
Father's age = 48
Daughter's age = 24
Step-by-step explanation:
Let x be father's age and y be daughter's age.
1st equation:
x = 2y
2nd equation:
(x - 16) = 4(y - 16)
Replacing value of x from 1st equation,
(2y - 16) = 4(y - 16)
2y - 16 = 4y - 64
4y - 2y = 64 - 16
2y = 48
y = 48/2
y = 24
And,
x = 2y
x = 2 x 24
x = 48
8x - x = 64 - 16
7x = 48
In ANOP, PN = OP and m_0 = 32°. Find m2P.
Which equation demonstrates the associative property of multiplication?
Answer:
A
Step-by-step explanation:
The parentheses are switched around, making the answer still the same. However, for Answer choice C, it is Commutative Property because the factors are switched around.
=====================================================
Explanation:
The equation shown for choice A is in the form p*(q*r) = (p*q)*r which is the general format for the associative property of multiplication.
In this case, p = 2.5, q = 1/5 and r = 2/3.
The order of p,q,r stays the same while the parenthesis shift around. The stuff in the parenthesis is done first before anything else. Though with multiplication, the order doesn't matter which is why we can freely shift the parenthesis like this.
Addition has a similar rule which says p+(q+r) = (p+q)+r.

HOW CAN YOU DETERMINE THE END BEHAVIOR OF A POLYNOMIAL FUNCTION?
Answer:
Hi there!
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis
I'm sorry if that is not clear enough!
Best wishes,
Pandora
Step-by-step explanation:
Answer:
as x approaches positive infinity or negative infinity, the degree and the leading coefficient of a polynomial function determines the end behavior of the graph

The probability that June wins in a raffle is given by the expression p . Write down an expression for the probability that June does not win
Answer:
1 - p
Step-by-step explanation:
Given
[tex]Winning = p[/tex]
Required
Determine the probability of not winning
To do this, we apply the complement rule which is:
[tex]Not\ Winning = 1 - Winning[/tex]
Substitute p for Winning
[tex]Not\ Winning = 1 - p[/tex]
Hence, the expression that June does not win is: 1 - p

Graph f(x) = 6x and g(x) = -6x. Then describe the transformation from the graph of f(x) to the graph of g(x)
Answer:
See explanation below
Step-by-step explanation:
The slope for f(x) is 6, meaning that you for each one x-unit you move, the plot goes up 6 y-units.
This is the same for g(x) but the slope is negative, so the line needs to face downwards. For each one x-unit you move, the plot goes down 6 y-units.
After drawing the two lines, you find that the transformation is a reflection because the lines are perpendicular to each other. They have the same slope, but in different directions.
the interest on a sum of rupess 5000 for 8 yrs at the interest rate 5% is???
Answer:
Rs. 200
Step-by-step explanation:
Formula: PTR/100
P=Rs.5000
T=8 years
R=5%
Interest = PTR/100
= (5000 x 8 x 5)/100
= Rs.200
Answer:
2000
Step-by-step explanation:
I=P×R×T
=5000×5/100×8
=25000×8
=200,000/100
=2000

Could someone please explain how to solve for the area?
9514 1404 393
Answer:
779.4 square units
Step-by-step explanation:
You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.
One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...
A = (1/2)r²sin(α)
Since there are n such triangles, the area of the n-gon is ...
A = (n/2)r²sin(360°/n)
__
For a hexagon (n=6) with radius 10√3, the area is ...
A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units
Divide £60 in a ratio of 2:1
£40 and £20
Step-by-step explanation:
let the parts be 2x and x (2:1)
2x+x=£60
or, 3x= £60
or, x= £20
2x=2×£20=£40
x=£20
Work out the Area of the shape
Answer:
145.8cm squared
Step by step:
16.2 divided by 3 = 5.4cm
In the second line where 2 bricks are horizontal and 2 are vertical:
2x + 3y = 16.2
3y = 16.2 - 2 x 5.4
y = 1/3 x 5.4
y = 1.8cm
Hence, height and length of each triangle is 1.8cm and 5.4cm
Complete length = 16.2 cm
Complete height = 2y + x = 2 x 1.8 + 3.4
= 9 cm
Area overall = 16.2 x 9 = 145.8cm squared
Martin has 64 sticks of gum altogether. How many packs of gum does he have?
help quickly!!!!! explanation needed. lots of points.
Answer:
29.3
Step-by-step explanation:
to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.
first we have to find the sum of the minutes she practiced:
20+30+40+38+25+22+39+22+26+31
this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:
293/10 =29.3

Question 3 (1 point)
A line passes through the point (2.3) and has a slope of 3. What is the equation of the line in
slope intercept form?
Answer:
y = 3x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 6 + c ⇒ c = 3 - 6 = - 3
y = 3x - 3 ← equation of line
