Answer: C -1.9
Step-by-step explanation:
The rate of change of this simple index over 1 week given the change in the stock prices is -1.9%.
What is the rate of change?
The rate of change is the difference in the total value of the simple index.
Total value of the simple index at day 1 = (4000 x $3.15) + (5000 x $4.30) + (6000 x $4.60) = $61,700
Total value of the simple index at day 8 = (4000 x $3.50) + (5000 x $3.90) + (6000 x $4.50) = $60,500
Rate of change = (60,500 / 61700) - 1 = -1.9%

What shape has 5 vertices and 3 sides
Answer:
a polygon
Step-by-step explanation:
A quadrilateral is a polygon. The shape that has more than 3 sides and less than 5 vertices is a quadrilateral.
What is a quadrilateral?A quadrilateral is a polygon with 4 number of sides and 4 vertices. A few examples of a quadrilateral are square, rectangle, rhombus, parallelogram, etc.
The complete question is: What shape has only straight sides more than 3 sides and has fewer than 5 vertices and can be cut into fourths?
Since we need to cut the shape into four equal parts, Also the number of sides should be greater than 3, while the number of vertices should be less than 5. Therefore, the shape that fits these criteria is a quadrilateral. For example, square, rectangle, etc.

The surface area of a piece of paper is 137 cm2. Use the fact that 10 mm = 1 cm to convert this area to mm2. Give your answer as a number. Do not type the units in the space below.
Solution:
surface area of a piece of paper = 137 sq cm
Use the fact that 10 mm = 1 cm to convert this area to mm^2
[tex]1\ cm = 10\ mm[/tex]
Then,
[tex]1\ cm^2 = 100\ mm^2[/tex]
Convert 137 sq cm to sq mm
[tex]137\ cm^2 = 137 \times 100\ mm^2\\\\137\ cm^2 = 13700\ mm^2[/tex]
Thus, surface area of a piece of paper is [tex]13700\ mm^2[/tex]
To convert the surface area of a piece of paper from cm² to mm², use the conversion factor 1 cm² = 100 mm².
Explanation:To convert the surface area of a piece of paper from square centimeters (cm²) to square millimeters (mm²), we can use the conversion factor that 10 mm = 1 cm. Since we are given the surface area as 137 cm², we can multiply it by the conversion factor to get the value in mm².
Conversion factor: 1 cm² = (10 mm)² = 100 mm²
Therefore, the surface area of the paper in mm² is 137 cm² x 100 mm²/cm² = 13700 mm².

Find the radius of circle if AB = 24 and OC = 5
Answer:
13
Step-by-step explanation:
Since OCB forms a right triangle, you can find the length of side OB and therefore the radius by simply using the pythagorean theorem. The first step is to note that, since AB=24 and OC bisects that, that both CB and AC have length 12. Therefore, the radius is [tex]BO=\sqrt{12^2+5^2}=13[/tex]. Hope this helps!

Determine the solution by using substitution. Write your answer as a point below (x,y).
Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
Answer:
(2,-2)

draw the image of quadrilateral ABCD under a translation by 2 units to the right and 5 units down
To draw the image of a quadrilateral under a translation, shift every point of the quadrilateral accordingly. The translated points form the new quadrilateral.
Explanation:To draw the image of quadrilateral ABCD under a translation by 2 units to the right and 5 units down, you need to shift every point of the quadrilateral 2 units to the right and 5 units downwards. For example, if point A was at (2,3), its new point after the translation would be at (2+2, 3-5) = (4,-2). You will need to do the same for points B, C, and D. Once you have the new coordinates for A, B, C, and D, simply connect them in the same order to get your translated quadrilateral. Remember that the shape and size of the quadrilateral will not change during the translation, only its position on the graph.

Use the elimination method to solve the system of equations. Choose the
correct ordered pair.
3x + 5y = 48
-3x+ 5y = 12
Answer: x=6
Y=6
Step-by-step explanation:
Using the elimination method
3x+5y=48.....equ1
-3x+5y=12......equ2
Add equation 1 &2
3x+5y=48
+
-3x+5y=12
Answer =
10y=60
Y=60/10
Y=6
Substitute for y in equation 1
3x+5y=48
3x+5(6)=48
3x+30=48
3x=48-30
3x=18
X=18/3
X=6
Therefore,
X= 6
Y= 6
Answer: x=6
Step-by-step explanation:
Let's solve your system of equations by elimination.
3x+5y=48;−3x+5y=12
Steps:
3x+5y=48
−3x+5y=12
Add these equations to eliminate x:
10y=60
Then solve
10y=60
for y:
10y/10=60/10
(Divide both sides by 10)
y=6
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
3x+5y=48
Substitute
6 for y in 3x+5y=48:3x+(5)(6)=48
3x+30=48
(Simplify both sides of the equation)
3x+30+−30=48+−30
(Add -30 to both sides)
3x=18
3x/3=18/3
(Divide both sides by 3)
x=6
you have five $1 bills, four $5 bills, six $10 bills, and three $20 bills you select a bill at random, without replacing the bill what is the probability of a 1 then a ten?
a.11/35
b.5/51
c.5/54
d.193/306
Answer:
Option B.
Step-by-step explanation:
It is given that,
Number of $1 bills = 5
Number of $5 bills = 4
Number of $10 bills = 6
Number of $20 bills = 3
So,
Total number of bills = 5 + 4 + 6 + 3 = 18
We need to find the probability of a 1 then a ten (without replacement).
Probability of selecting $1 bill in first draw [tex]=\dfrac{5}{18}[/tex]
After one draw, the number of remaining bills is 18 - 1 = 17.
Probability of selecting $10 bill in second draw [tex]=\dfrac{6}{17}[/tex]
The probability of a 1 then a ten is
[tex]P=\dfrac{5}{18}\times \dfrac{6}{17}=\dfrac{5}{51}[/tex]
Therefore, the correct option is B.

Measure of E is congruent to K, so E is 50 degrees.
Measure of G is congruent to L, so G is 105 degrees.
Measure of F is congruent to J, J is 180 deg - 50 deg - 105 deg = 25 degrees, so F is 25 degrees.

Find the area of a circle with a circumference of 50.24 units
Answer:
A = 200.96 units^2
Step-by-step explanation:
We know the circumference is given by
C = 2 * pi *r
Approximating pi by 3.14
50.24 = 2 * 3.14 *r
50.24 = 6.28 r
Divide each side by 6.28
50.24/ 6.28 = 6.28r/6.28
8 =r
Now we can find the area
A = pi * r^2
A = 3.14 * r^2
A = 3.14 (8)^2
A = 200.96 units^2

x(x - 1) + 3(x - 1) ← distribute both parenthesis
x² - x + 3x - 3 ← collect like terms
= x² + 2x - 3
Answer:
x^2+2x−3
Step-by-step explanation:
lets use the multiplication property of distrubution.
x * x = x^2
x * -1 = -x
(x+3)(x−1)
=(x+3)(x+−1)
=(x)(x)+(x)(−1)+(3)(x)+(3)(−1)

In the figure below, the radius of circle P is 18 units. The arc length of BA is
14.
What is the arc measure of BC, in degrees?
Answer:
The arc measure of BC is 64
Step-by-step explanation:
1. Calculate the full circumference of the circle
C=2pir
=2pi(18)
=36pi
2. Figure out the arc measure
arc length/circumference=arc measure/degrees in a circle
14pi/36pi=arc measure/360 (solve for arc measure)
14pi/36pi *360=140
The measures of BC and CA add up to the measure of BA
mBC +76=140
BC=64
Emily and Lydia go to the movie theater and purchase refreshments for their friends. Emily spends a total of $78.50 on 2 bags of popcorn and 8 drinks. Lydia spends a total of $89.50 on 4 bags of popcorn and 7 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
The price of one drink is $7.5
The price of one bag of popcorn is $9.25
Step-by-step explanation:
Let us assume,
The price of one bag of popcorn = xThe price of one drink = yEmily spends a total of $78.50 on 2 bags of popcorn and 8 drinks.
⇒ 2x + 8y = 78.5 -------(1)
Lydia spends a total of $89.50 on 4 bags of popcorn and 7 drinks.
⇒ 4x + 7y = 89.5 --------(2)
To solve for x and y values :
Multiply eq (1) by 2 and subtract eq (2) from eq (1),
4x + 16y = 157
- (4x + 7y = 89.5)
9y = 67.5
⇒ y = 67.5/9
⇒ y = 7.5
∴ The price of one drink is $7.5
Substitute y = 7.5 in eq (1),
⇒ 2x + 8(7.5) = 78.5
⇒ 2x + 60 = 78.5
⇒ 2x = 78.5 - 60
⇒ 2x = 18.5
⇒ x = 18.5/2
⇒ x = 9.25
∴ The price of one bag of popcorn is $9.25
