The distance between the points are therefore:
(3,-1) and (5,4):
Distance = √[(5 - 3)² + (4 - (-1))²] = √[(2)² + (5)²]
= √[4 + 25] = √[29]
= 5.39
(2,3) and (4,5):
Distance = √[(4 - 2)² + (5 - 3)²] = √[(2)² + (2)²]
= √[4 + 4] = √[8]
= 2.83
(-5,7) and (8,5):
Distance = √[(8 - (-5))² + (5 - 7)²] = √[(13)² + (-2)²]
= √[169 + 4] = √[173]
= 13.15
(-2,4) and (3,-1):
Distance = √[(3 - (-2))² + ((-1) - 4)²] = √[(5)² + (-5)²]
= √[25 + 25]
= √[50]

2/3c=18 what does c equal to
Answer: 27
Step-by-step explanation:
Answer:
c = 27
Step-by-step explanation:
Solve for c:
(2 c)/3 = 18
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (2 c)/3 = 18 by 3/2:
(3×2 c)/(2×3) = 3/2×18
Hint: | Express 3/2×2/3 as a single fraction.
3/2×2/3 = (3×2)/(2×3):
(3×2)/(2×3) c = 3/2×18
Hint: | Express 3/2×18 as a single fraction.
3/2×18 = (3×18)/2:
(3×2 c)/(2×3) = (3×18)/2
Hint: | Cancel common terms in the numerator and denominator of (3×2 c)/(2×3).
(3×2 c)/(2×3) = (2×3)/(2×3)×c = c:
c = (3×18)/2
Hint: | In (3×18)/2, divide 18 in the numerator by 2 in the denominator.
18/2 = (2×9)/2 = 9:
c = 3×9
Hint: | Multiply 3 and 9 together.
3×9 = 27:

Step-by-step explanation:
In the figure attached,
V, W, X, Y and Z are collinear.
VZ = 52, XZ = 20 and WX = XY = YZ
21). Since XZ = 20
XY + YZ = 20

2(WX) = 20
WX = 10
22). VZ = VW + WX + XY + YZ = 52
VW + 3(YZ) = 52 [Since, WX = XY = YZ]
VW + [tex]3(\frac{XZ}{2})[/tex] = 52
VW + [tex]\frac{3}{2}\times 20[/tex] = 52
VW = 52 - 30 = 22
23). WY = WX + XY

Answer:
(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.
Can't read the second question fully.
(A) 0.53
Step-by-step explanation:
Number 1:
If we have the equation [tex]3x + 2 = 5x[/tex], our first goal is to get rid of the x term on one side.
To do this we can subtract 3x from both sides. This leaves our equation to [tex]2=2x[/tex]. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x. This leaves [tex]x=1[/tex].
I couldn't read Number 2 fully - I'm sorry :c
Number 3:
Given the equation [tex]3(x+0.2)=2.2[/tex], we want to isolate x on one side.
To do this, we first apply the distributive property to the left side.
[tex]3x + 0.6 = 2.2[/tex]
Now subtract 0.6 from both sides:
[tex]3x=1.6[/tex]
And divide both sides by 3.
[tex]x=0.5\overline{3}[/tex]
This rounds to 0.53.
Hope this helped!
Answer:
B

A
Step-by-step explanation:
Equation
3x + 2 = 5x
The first step is to subtract 3x from both sides.
3x - 3x + 2 = 5x - 3x
2 = 2x
The next step is to divide by two. That's the 2 in front of the two x.
2/2 = 2x/2
1 = x
So the answer must be B

First solve for x, then find ∡RQW. ∡WQP=139+x, ∡RQW=31+x & ∡RQP=152°
Answer:
[tex]x = -9[/tex]
[tex]RQW = 22[/tex]
Step-by-step explanation:
Given
[tex]WQP = 139 + x[/tex]
[tex]RQW = 31 + x[/tex]
[tex]RQP = 152[/tex]
Required
Determine x and WQP
From the attachment;
[tex]RQP = RQW + WQP[/tex]
Substitute 152 for RQP, 31 + x for RQW, 139 + x for WQP
[tex]152 = 31 + x + 139 + x[/tex]
Collect Like Terms
[tex]152 - 31 - 139 = x + x[/tex]
[tex]-18 = 2x[/tex]
Divide both sides by 2
[tex]\frac{-18}{2} = x[/tex]
[tex]x = -9[/tex]
To solve for RQW; substitute -9 for x in RQW = 31 + x
[tex]RQW = 31 + (-9)[/tex]
[tex]RQW = 31 -9[/tex]
[tex]RQW = 22[/tex]

A square image of an object on a video game has an initial side length of 25 pixels. To make the object appear closer, the side length of the square is increased by 10 pixels per second. This length change is represented by the function s(t) = 25 + 10t, where t is time in seconds. If the area of the square is A(s) = sa, find the formula for the area as a function of time, and then determine A(s(3)). A(t) equals +2+ t + 625 The area of the square image after 3 seconds is square pixels.
Answer: A(t) = 100t^2 + 500t + 625
3,025 square pixels
Step-by-step explanation:
A function assigns the values. The area of the square image after 3 seconds is 3,025 sq. pixels.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A.) The area of the video game will be,
A(s) = [s(t)]²
A(s) = (25+10t)²
A(s) = 625 + 100t² + 500t
A(s) = 100t² + 500t +625
B.) The value of A(s(3)) will be,
A(s(t)) = 100(25+10t)² + 500(25+10t) + 625
A(s(t)) = 10,000t² + 50,000t + 62,500 + 12,500 + 5,000t + 625
A(s(t)) = 10,000t² + 55,000t + 75,625
A(s(3)) = 10,000(3)² + 55,000(3) + 75,625
A(s(3)) = 270,000 + 165,000 + 75,625
A(s(3)) = 510,625
The area of the square image after 3 seconds is,
A(s) = 100t² + 500t +625
A(3) = 100(3)² + 500(3) +625
A(3) = 900 + 1500 +625
A(3) = 3,025
Hence, The area of the square image after 3 seconds is 3,025 sq. pixels.

You have $250 comma 000 in an IRA (Individual Retirement Account) at the time you retire. You have the option of investing this money in two funds: Fund A pays 2.4% annually and Fund B pays 7.4% annually. How should you divide your money between Fund A and Fund B to produce an annual interest income of $9 comma 000?
Answer:
$190,000 goes to fund A while $60,000 goes to fund B to earn an annual interest income of $9,000
Step-by-step explanation:
Here, we are interested in knowing the way the money should be divided between the interest rates to give an annual interest totaling $9,000.
Let’s have the amount going to Fund A as $x while $y is the amount going to Fund B.
Although, we do not know the value of these amounts, we know that they both total $250,000
Thus, mathematically;
x + y = 250,000 •••••••••••(i)
Now also, let’s work with the percentages to get the interests:
For fund A;
2.4% of x = interest
2.4/100 * x = 2.4x/100
For fund B;
7.4% * y = interest
7.4/100 * y = interest
7.4y/100 = interest
Adding both gives a total of $9,000
Mathematically, that would be;
2.4x/100 + 7.4y/100 = 9,000
Multiply through by 100;
2.4x + 7.4y = 900,000 •••••••(ii)
From i, x = 250,000 -y
Substitute this into ii
2.4(250,000-y) + 7.4y = 900,000
600,000 -2.4y + 7.4y = 900,000
Collecting like terms, we have;
7.4y-2.4y = 900,000-600,000
5y = 300,000
y = 300,000/5
y = $60,000
But x = 250,000 - y
x = 250,000 - 60,000
x = $190,000

Step-by-step explanation:
for 5 you just subtract the given values from 360
Answer:
1a) A
(both B and C intersect at A)
1b) not sure
2a) draw 270 degree angle
360/4 = 90
90+90+90 = 270 = 3/4
2b) draw an angle less than 90 degree to get an acute angle
3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees
90/2 = 45
but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it
3b) draw a 90 degree angle facing downward and thats 270 degree
hope you get what im trying to say if not you can ask me again
4a) acute angle (90 degree)
4b) reflex angle (180 degree)
5a) 112 degree
118 + 130 + x = 360
248 + x = 360
x = 360 - 248
x = 112
5b) 145 degree
360 - 215 = 145
im posting the solutions and the answers of your previous questions here
6a) a = 60 degree
6b) b = 27 degree
because sum of interior angles of a triangle is 180
7a) b = 60 degree and a = 30 degree
7b) x = 36 degree and x = 36 degree
isosceles triangle has 2 same angles and 1 different
x + x + 108 = 180
2x + 108 = 180
2x = 180 - 108
2x = 72
x = 72/2
x = 36
8a) x = 95 degree
8b) a = 100 degree
9) steps;
draw a line segment QR
draw 120 degree angle at point Q
now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O
now from point O, open your compass of same measurement and draw an arc that cuts the previous arc
now draw a line from point Q to join the new formed arc
now using a protactor measure both the newly formed angles

The height of a triangle is 4 inches. Greater than twice it's base. The area of the triangle is no more than 168 in.². Which any quality can be used to find the possible lengths, x, of the base of the triangle
Step-by-step explanation:
this problem seeks to test our knowledge on word problems and algebra
Solution
let the base be x, and
the height h = 2x+4
We know that area of a triangle is given as
[tex]A= \frac{1}{2} b*h[/tex]
substituting our given values we have
[tex]168= \frac{1}{2} x*(2x+4)\\\\168= \frac{2x^2+4x}{2} \\\\168= x^2+2x\\\\[/tex]
re-arranging we have
[tex]x^2+2x-168=0\\\\[/tex]
we can now find two factors that will add up to give 2 and multiply to give -168
they are 14 and -12
[tex]x^2-14x+12x-168=0\\\\x(x-14)+12(x- 14)=0\\\\x+12=0\\\\x=-12\\\\x-14=0\\\\x=14[/tex]
The possible base of the triangle is 14 in
and the height is
[tex]h= 2x+4\\\\h=2(14)+4\\\\h= 28+4\\\\\h= 32 in[/tex]
