Consider the line segment PQ with endpoints P(- 3, - 2) and Q(2, 3). Which point divides the line segment directed from P to Q in the ratio of 3:2?
Answer:
(0,1) point C
Step-by-step explanation:
the line segment PQ is divided into 5 parts ( 3parts +2 parts)
Is very important that you keep the direction correct from P to Q
The point C divides the PQ into 3:2 ratio
(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.
Vectorially speaking, we determine the the location of the point that divides the line segment in the ratio of [tex]a : b[/tex].
[tex]R(x,y) = P(x,y) + \frac{a}{a+b}\cdot [Q(x,y) - P(x,y)][/tex] (1)
Where:
[tex]P(x,y)[/tex], [tex]Q(x,y)[/tex] - Endpoints.[tex]R(x,y)[/tex] - Resulting point.If we know that [tex]P(x,y) = (-3, -2)[/tex], [tex]Q(x,y) = (2, 3)[/tex], [tex]a = 3[/tex] and [tex]b = 2[/tex], then the location of the resulting point:
[tex]R(x,y) = (-3, -2) + \frac{3}{5}\cdot [(2,3)-(-3,-2)][/tex]
[tex]R(x,y) = (-3,-2) +\frac{3}{5}\cdot (5, 5)[/tex]
[tex]R(x,y) = (-3, -2) + (3,3)[/tex]
[tex]R(x,y) = (0, 1)[/tex]
(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.

to solve the question we need to recall one of the most important theorem of circle known as two tangent theorem which states that tangents which meet at the same point are equal that is being said
FA=AI=17CH=CG=2.5since [tex]\rm BA=FA+FB[/tex] and it's given that FA and BA are 17 and 29 FB should be
[tex]\rm 29=17+FB[/tex]therefore,
[tex]FB=29-17=\boxed{12}[/tex]once again by two tangent theorem we acquire:
[tex]FB=BH=\boxed{12}[/tex]As BC=BH+CH,BC is
12+2.5[tex]\boxed{14.5}[/tex]likewise,AD=AI+DI so,
21=17+DI [AD=21(given) and AI=17 (by the theorem)]thus,
DI=21-17=[tex]\boxed{4}[/tex]By the theorem we obtain:
DI=DG=4Similarly,DC=DG+CH therefore,
DC=4+2.5=[tex]\boxed{6.5}[/tex]Now finding the Perimeter of ABCD
[tex]P_{\text{ABCD}}=\text{AB+AD+BC+DC}[/tex]substitute what we have and got
[tex]P_{\text{ABCD}}=\text{29+21+14.5+6.5}[/tex]simplify addition:
[tex]P_{\text{ABCD}}=\boxed{71}[/tex]hence,
the Perimeter of ABCD is 71

Find the volume of the cone.
Either enter an exact answer in terms of
π
πpi or use
3.14
πpi and round your final answer to the nearest hundredth.
Answer:
V = 18.84 units³
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(pi)(r²)(h).
Here, with pi = 3.14, r = 3 and h = 2, we get:
V = 18.84 units³

You roll a standard number cube 36 times, how many times can you expect to roll an odd number?
Answer:
18 times
Step-by-step explanation:
Half of the possibilities you can roll are correct. so 18 out of 36 times you roll an odd number.
You could also look at it another way. You can expect to roll each number 6 times, so the 3 odd numbers added together is 18 times.

Find the value of x in the figure shown.
Answer:
x= 17
Step-by-step explanation:
Assuming that the total degree of this side is also 90, we'll subtract 90 with 39.
90 - 39= 51
since x is 3 times the total degree, we'll divide 51 by 3, leaving us with 17.
Declan says that any number n, the product 4 times n is greater than 4. Which value of n shows why declan is incorrect
Answer: [tex]n>1[/tex]
Step-by-step explanation:
Given
The product of 4 times n is greater than 4 i.e.
[tex]\Rightarrow 4\times n>4\\\text{Dividing both side of inequality by 4}\\\\\Rightarrow \dfrac{4n}{4}>\dfrac{4}{4}\\\\\Rightarrow n>1[/tex]
It can be said that the value of n must be greater than 1.

Step-by-step explanation:
Volume of a pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]
Area of the rectangular base = Length × Width
= 8 × 6
= 48 mm²
Volume of the pyramid = 192 mm³
192 = [tex]\frac{1}{3}(48)h[/tex]
h = [tex]\frac{192}{16}[/tex]
h = 12 mm
Therefore, all the pyramids having height less than 12 mm will be fitted inside the given pyramid.

I got the tax amount and tip amount and added them.
Answer:
Step-by-step explanation:

tax=52×7 %=3.64$
tip=52×20%=10.40$
total cost of meal=52+3.64+10.40=66.04 $
Which statements about this system of equations are true? Check all that apply. Negative x + 6 y = 16. 8 x minus 6 y = negative 2. The x-variable will be eliminated when adding the system of equations. The y-variable will be eliminated when adding the system of equations. The sum of the system of equations is Negative 8 x = 14. X = 2 y = 3 There is only one solution to the system of equations.
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)

Which point has coordinates (-5, -5) ?
Please help ASAP!! I will give 20 points !! for correct answer
Answer:
Your answer is S
Step-by-step explanation:
You move 5 to the left on the X axis, side to side.
Then you move 5 down on the Y axis, up and down.
What coordinates are reflection along the x-axis from the coordinates (4, - 2)? A (-4,-2) B (4,-2) C (-2,4) D (4,2)
Answer:
Option D
Step-by-step explanation:
Rule for the reflection of a point (x, y) over the x-axis is given by,
(x, y) → (x, -y)
Applying this rule image point of a point (4, -2) will be,
(4, -2) → (4, 2)
Therefore, Option D will be the correct option.
