The points A, B and C have position vectors OA = 6,2, OB = 3,4 and OC = 12, -2 respectively.
Express the vector:
a) BA
b) BC
Answer:(a) BA = (-3,2) (b) BC = (-9,6)
Step-by-step explanation: (a) Vector BA = position vector of B - position vector of A = vector OB - vector OA = (3-6) i + (4-2) j = -3i+2j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-3,2). (b) Vector BC = position vector of B - position vector of C = vector OB - vector OC = (3-12) i + (4-(-2)) j = -9i+6j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-9,6).

HELP please this is urgent!!!!! (Tangent lines)
Answer:
Perimeter = 32 cm
Step-by-step explanation:
Use the property of tangents drawn to a circle,
"Length of tangents drawn to a circle drawn from a point given outside the circle are equal"
AE = AH = 3 cm
BE = FB = 4 cm
CG = CF = 5 cm
Since, ∠B ≅ ∠D,
Therefore, length of tangents drawn from D will be equal to the length of tangents drawn form B.
Therefore, DG = DH = 4 cm
Now AB = AE + BE
= 3 + 4
= 7 cm
BC = FB + CF
= 4 + 5
= 9 cm
CD = CG + DG
= 5 + 4
= 9 cm
AD = AH + HD
= 3 + 4
= 7 cm
Perimeter of ABCD = AB + BC + CD + AD
= 7 + 9 + 9 + 7
= 32 cm
What is the radius of a sphere with a volume of 3026 cm ^3, to the nearest tenth of a centimeter?
Answer:
[tex]r=9.0\:\mathrm{cm}[/tex]
Step-by-step explanation:
The volume of a sphere is given as [tex]\frac{4}{3}r^3\pi[/tex]. Therefore we have the following equation:
[tex]\frac{4}{3}r^3\pi=3026,\\r^3=\frac{3}{4}\cdot\frac{3026}{\pi},\\r^3=722.40428,\\r=\sqrt[3]{722.40428},\\r\approx \fbox{$9.0\:\mathrm{cm}$}[/tex].
Rounding this to the nearest tenth of a centimeter, the radius of the sphere is approximately 14.0 cm.
What is volume?Volume refers to the amount of space occupied by an object or substance. In mathematics, it is usually measured in cubic units (e.g. cubic meters, cubic centimeters).
The volume of an object can be calculated using its dimensions and specific formulas that depend on the shape of the object.
For example, the volume of a cube is calculated by multiplying its length, width, and height, while the volume of a sphere is calculated using the formula [tex](4/3)\pi r^3[/tex], where r is the radius of the sphere.
The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius of the sphere and π (pi) is a mathematical constant approximately equal to 3.14159.
We can rearrange this formula to solve for r:
r = [tex](3V/4\pi)^{(1/3)[/tex]
Substituting the given volume V = 3026 [tex]cm^3[/tex], we get:
r = [tex](3(3026)/(4\pi))^{(1/3)[/tex] ≈ 14.0 cm
Thus, the radius of the sphere is approximately 14.0 cm, rounded to the nearest tenth of a centimetre.

You open a drink stand where you sell coffee and hot chocolate. You sell coffee for $1.80 and hot chocolate for $3.15. At the end of the day, you sold 120 cups and the total money you earned was $284.40. How many of each type of drink did you sell?
Answer:
c = 69 and h = 51
Step-by-step explanation:
You will need two different equations here
use variable c as coffee and variable h as hot chocolate
c + h = 120
1.80c + 3.15h = 284.40
By moving variables, you can alter the first equation
h = 120 - c
Now insert this into the second equation
1.80c + 3.15(120 - c) = 284.40
Multiply
1.80c + 378 - 3.15c = 284.40
Subtract the c
-1.35c + 378 = 284.40
Subtract 378 from both sides
-1.35c = -93.6
Divide both sides by -1.35
c = 69
Then plug into the first equation
69 + h = 120
Subtract 69
h = 51
jazmines dog weights 63 pounds. Her vet told her that a healthy weight for her dog would be less than or equal to 47 pounds. Jazmines dog can lose an average of 6 pounds every week. Write the solution to an inequality that describes all posible number of weeks x for which her dog can be at a healthy weight
Answer:
2 weeks and 4 days
Step-by-step explanation:
she is 63 pounds and she needs to get to 47 so 63-47=16 then if she loses 6 pounds every week then 6+6=12 which make 2 weeks cause we used two 6's so now we have a remainder which makes days 12-16=4 so their ya go

If P(A)=0.54 then what value of P(B) the event A and B are complementary event
Answer:
P(B) = 0.46
Step-by-step explanation:
Probability
The complementary event of a given event A is defined as "not A" or the event that A does not occur.
For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.
Event A and its complementary event (call it B) must satisfy:
P(A) + P(B) = 1
If we know P(A)=0.54, then
P(B) = 1 - P(A)
P(B) = 1 - 0.54
P(B) = 0.46

A local venue is selling tickets to a show. They are selling $10 and $15 tickets, each with different seating. If the venue sells 1,000 tickets and collects a total of $12,200 from sales, how many of each type of ticket did they sell? Please explain the work
Answer:
Let $10 tickets be (x)
Let $15 tickets be (y)
Now we know they sold 1000 tickets
And they earned 12,200 from sales
So we can say
X+Y=1000
10x+15y=12,200
We can do substitution
So lets find Y first
Y=1000-x (basically x+y=1000 but solved for Y)
10x+ 15 ( 1000-x)= 12,200
You’d get
10x+15000-15x=12200
Combine and solve for x and you’ll get
x=560
So we know that x is 560
We can just use that to solve for Y
Since X is 560 tickets
And 1000 tickets soled
1000-560=440
440 ($15) tickets
560 ($10) tickets

17. The sum of four consecutive integers is at most 100. Find the integers.
and solve.
Answer:
23,24,25,26
Step-by-step explanation:
X+(x+1)+(x+2)+(x+3)= 100
4x+6=100
4x=100-6
X=94/4
X=23.5
Ads the sum is said to be AT MOST 100 SO WE WILL ROUND DOWN THE NUMBER
So x=23
X+1=24
X+2=25
X+3=26
Sum=23+24+25+26=98
98<100 so answer is correct

How do I find n in the the permutation equation of nP3 = 990
Answer:
n=11
Step-by-step explanation:
Permutations
The formula to calculate permutations is:
[tex]\displaystyle nPm=\frac{n!}{(n-m)!}[/tex]
We know nP3=990. Substituting:
[tex]\displaystyle nP3=\frac{n!}{(n-3)!}=990[/tex]
Expanding the factorial in the numerator:
[tex]\displaystyle \frac{n(n-1)(n-2)(n-3)!}{(n-3)!}=990[/tex]
Simplifying:
[tex]n(n-1)(n-2)=990[/tex]
This equation can be easily solved by inspection. The product of three consecutive numbers resulting 990. Starting from greatest to smallest, those numbers are 11,10, and 9, thus:
[tex]n(n-1)(n-2)=11*10*9[/tex]
It follows that n=11
the difference of 18 and m is equal to the product of m and 7
Answer:
M = 11/2
Step-by-step explanation:
first set up the problem
18-m = m+7
subtract m to both sides
18 -2m = 7
then subtract 18
-2m = -11
divide by negative 2
m = 11/2

Write an equation of the line
in slope intercept form that
has a slope of -6 and
passes through the point
(2, -4).
Answer:
y=-6x+8
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept.
We know a point (2,-4) and a slope -6.
We can subtsitute what we know into the equation above, to find what the y intercept is, since the line will pass through the point given.
-4=-6(2)+b
multiply
-4=-12+b
add 12 to both sides
8=b
the y intercept is (0,8)
Now we know what b is, so we know what the full equation is:
y=-6x+8

if MP= 6x-5, QR = 3x+1 ,and RN = 6, what is QN
Answer:
19 units.
Step-by-step explanation:
Consider the below figure attached with this question.
From the below figure it is given that MN=PQ.
It is given that MP = 6x – 5, QR = 3x + 1, and RN = 6.
Since non parallel sides are equal, therefore it is an isosceles trapezoid.
The diagonals of an isosceles trapezoid are equal.
Substitute the given values.
The value of x is 4.
Hence, the measure of QN is 19 units.

Step-by-step explanation:
9514 1404 393
Answer:
ED = 26; CF = 13; arc ED = 136°; arc HD = 68°; arc CE = 88°
QU = 8; QR= 16; arc ST = 114°; arc QR = 114°; arc XT = 57°
Step-by-step explanation:
Chords the same distance from the center of the circle are the same length. Chords of the same length intercept arcs of the same angle measure. A radius perpendicular to a chord bisects it and the arc it subtends. The sum of arcs in a circle is 360°. These facts are used to solve the problems here.
__
Circle J
ED = 2×GD = 26
CF = GD = 13
arc ED = arc CD = 136°
arc HD = 1/2 arc CD = 68°
arc CE = 360° - 2×136° = 88°
__
Circle Y
QU = 1/2×ST = 8
QR = ST = 16
arc ST = arc QR = 1/2(360° -34° -98°) = 114°
arc XT = 1/2 arc ST = 57°
