What is the slope of the line shown?
Answers
Answer: slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Since we are given a graph with clear points, we will use "rise over run" by counting the units between points upwards and rightwards.
Since this line is going up from bottom left to upper right, we have a positive slope.
Starting at (0, -3) we count up one unit and right two units to (2, -2), giving us a slope of [tex]\frac{1}{2}[/tex].
solve a woman started a business by birr 3000. she lost birr 100 in the first month and birr 60 in the second month , birr 20 in the third month and so on. assuming thus improvement continued at the same rate ,determune her total capital in two years and 7 months
Answers
The total capital in for the woman in two years and 7 months is Birr 1800.
How to calculate the value?It's important to note that 2 years and 7 months in months will be:
= (2 × 12) + 7
= 24 + 7
= 31 months
The first term on the information is 3000. The common difference is (60 - 100) = -40.
Therefore, the value for the 31st term will be:
= a + (n - 1)d
a = first term = 3000
n = number = 31
d = difference = -40
= 3000 + (31 - 1) × (-40)
= 3000 + (30 × -40)
= 3000 - 1200
= 1800
This is the capital after 31 months.

Given the equation:
[tex]6x=2x^3+11x^2[/tex]Let's solve the equation for x.
Rearrange the equation:
[tex]2x^3+11x^2=6x[/tex]Subtract 6x from both sides:
[tex]\begin{gathered} 2x^3+11x^2-6x=6x-6x \\ \\ 2x^3+11x^2-6x=0 \end{gathered}[/tex]Now, let's factor the left side of the equation.
Factor out x from all terms:
[tex]x(2x^2+11x-6)=0[/tex]The next step is to factor by grouping.
We have:
[tex]\begin{gathered} x(2x^2-1x+12x-6)=0 \\ \\ x((2x^2-1x)(12x-6))=0 \end{gathered}[/tex]factor out x from the first group and factor out 6 from the second group:

1) Given that MN is the midsegment, it means that
MN = 1/2(WZ + XY)
MN = 1/2(11 + 3) = 1/2 * 14
MN = 7
2) The base angles are congruent. This means that
angle WZN = angle XWZ = 78
The top angles are equal. The sum of the base angles is 78 + 78 = 156
Since the sum of all the angles is 360, the sum of each top angle is
(360 - 156)/2 = 102 degrees. This means that
angle WXY and angle ZYX = 102
Angle XMN and angle XWN are congruent. This is because they are corresponding angles. thus,
angle XMN = 78 degrees
3) Recall, MN = 1/2(WZ + XY)
If MN = 10 and WZ = 14, then
10 = 1/2(14 + XY)
10 * 2 = 14 + XY
20 = 14 + XY
XY = 20 - 14
XY = 6
4) Recall that angle MWZ = angle WZN because they are the base angles. Given that angle MWZ = 15x - 5 and angle WZN = 90 - 4x, it means that
15x - 5 = 90 - 4x
15x + 4x = 90 + 5
19x = 95
x = 95/19
x = 5

[tex]D\colon x\ge0[/tex]investment account opened with $7500, at the end of the year the amount in the account had increased by 23.8% How much is this increase in dollars? how much money was in the account at the end of last year?
Answers
Hello!
First, let's analyze the exercise and write important information:
• investment account ,opened with $7500
,• at the ,end of the year,, the amount in the account had, increased by 23.8%
Knowing this information, we are able to solve your exercise, look:
The account was opened with 7500 (that means 100%).
As there was an increase of 23.8%, we can say that after one year the account had 123.8%.
So, let's solve it using the rule of three:
[tex]\frac{7500\rightarrow100}{x\rightarrow123.8}[/tex]Let's multiply it across:
[tex]\begin{gathered} (100\cdot x)=(7500\cdot123.8) \\ 100x=928,500 \\ x=\frac{928,500}{100} \\ \\ x=9,285 \end{gathered}[/tex]So at the end of the year, there were $9285 in the account
To obtain the increase in one year, we can subtract the final value by the initial value, look:
$9285 - $7500 = $1785

What is the cardinality of the set W = {x | x is a day of the week} ?
Answers
Answer:
7
Explanation:
The cardinality of a set is the number of elements in the set
Given the set W = {x | x is a day of the week}
The days of the week are {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}
Hence the set W will be;
W = {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}
n(W) = 7 (since there are 7 days in a week)
Hence the cardinality of the set W is 7

We were given the following information:
A rose garden is formed by joining a rectangle and a semicircle, as shown below:
Rectangle: Length = 23 feet, Width = 15 feet
Semicircle: Diameter = 15 feet; radius = Diameter/2 = 15/2 = 7.5 feet
Pi = 3.14
We will calculate the perimeter of the garden as shown below:
[tex]\begin{gathered} Perimeter_{garden}=Perimeter_{rectangle}+Perimeter_{semicircle} \\ Perimeter_{rectangle}=2(length+width)=2(23+15)=2(38)=76ft \\ Perimeter_{semicircle}\Rightarrow\frac{1}{2}Perimeter_{circle}\Rightarrow\frac{1}{2}\times2\pi r=\pi r=3.14\times7.5=23.55ft \\ Perimeter_{garden}=76+23.55=99.55 \\ Perimeter_{garden}=99.55ft \\ \\ \therefore Perimeter_{garden}=99.55ft \end{gathered}[/tex]Therefore, the gardener will need to build a fence of length 99.55 feet
