Answer:
[tex]2 - i[/tex]
Step-by-step explanation:
Substitute i for x. Remeber i means imaginart number.
[tex] {i}^{3} - 2 {i}^{2} [/tex]
Use the Imaginary number exponents rules
[tex] {i}^{2} = - 1[/tex]
[tex] {i}^{3} = - i[/tex]

The area of the shape is [ ]
square meters.
(50 points ^^)
Answer:
44m²
Step-by-step explanation:
GIVEN :-
Lengths of all the sides of the figure.TO FIND :-
Area of the figureSOLUTION :-
Divide the whole figure into 2 rectangles.
Dimension of 1st rectangle = 6m × 2mDimension of 2nd rectangle = 8m × 4mArea of 1st rectangle = 6 × 2 = 12m²
Area of 2nd rectangle = 8 × 4 = 32m²
∴ Area of the whole figure = 32 + 12 = 44m²
A pharmaceutical company is testing a new drug. For the study, the company enrolled 200 people who had previously been diagnosed with a specific condition. Half took the study drug and half took a placebo. Throughout the study, the participants were routinely asked to fill out a 50-question survey. After six months, the participants on the study drug showed positive improvements in their answers. What is the best way the company could improve this study to prove more thoroughly that its medications work
Answer:
The quantitative data must be collected and test statistics performed.
Step-by-step explanation:
The quantitative data must be collected by performong different test such blood test etc. Then the improvement in the medications work can be found out by applying different test statistics such as difference tests , etc.
The quantititave data will show how much there has been improvement by using drugs and placebo.
The test statistic will provide a basis for the quick decision without waiting for 6 months.

x^2-3=0 solve for all real values of x
Step-by-step explanation:
x²-3=0
x²=3
x=√3
stay safe healthy and happy.Answer:
x = √3
x = - √3
Step-by-step explanation:
x^2 - 3 = 0 Add 3 to both sides
x^2 = 3 Take the square root of both sides.
sqrt(x^2) = sqrt(3)
x = +/- sqrt(3)
Remember that the - root is also a solution to the question. Also for this question don't put the - sign under the root sign. That is an entirely different question.

he or she is taking. This table show the responses. Select all the statements that are valid based on the results of
the survey.
Science Class

Chemistry
Biology
Earth Science
Health Science
Number of
Students
6
10
18
A. About 20% of students at the high school are taking
Chemistry.
B. About twice as many students are taking Health Science
than are taking Physics.
C. For every 150 students we could predict that at least 18
of the students are taking Physics.
D. For every 25 students we could predict that at least 4 of
the students are taking Earth Science.
4
12
Answer:
A, B, C
Step-by-step explanation:
The total number of students is the sum of the students taken each course. Hence the total number of students is:
Total number = 6 + 10 + 18 + 4 + 12 = 50 students
A) The percentage of students offering chemistry = (number of students offering chemistry / total number of students) * 100%
percentage of students offering chemistry = (10 / 50) * 100% = 20%
Option A is correct
B) number of students taking health science = 12, while number of students taking physics = 6. Hence About twice as many students are taking Health Science than are taking Physics.
Option B is correct.
C) The percentage of students taking physic = (6 / 50) * 100% = 12%
Therefore for 150 students, the number of students taking Physics = 12% * 150 = 0.12 * 150 = 18
Option C is correct
D) The percentage of students taking earth science = (4 / 50) * 100% = 8%
Therefore for 25 students, the number of students taking earth science = 8% * 25 = 0.08 * 25 = 2
For every 150 students we could predict that 18 of the students are taking Physics.
Option D is correct
A rectangle has a width of 6 and a length of 2x+8. The area is 108 squared, what is the value of x?
Answer:
x = 5
Step-by-step explanation:
108 = 6(2x + 8)
108/6 = 18
18 = 2x + 8
18 - 8 = 10
10 = 2x
10/2 = 5
5 = x

A developer is building a scale model of the city. From the roof of an apartment complex, the developer points two lasers at the taller office building across the street. The first laser points to the base of the building and the second laser points to the top of the building. The first laser beam has an angle of depression of 36° and is 155.7 feet long. The second has an angle of elevation of 32° and is 148.6 feet long. How tall is the office building? How far apart are the apartment complex and the office building? Round your answers to the nearest foot.
Answer:
a. 170 ft b. 126 ft
Step-by-step explanation:
a. How tall is the office building?
The two laser lights with the length of the taller office building, L form a triangle with sides 155.7 feet, 148.6 feet and L with angle 36° + 32° = 68° facing the taller office building.
We use the cosine rule to find the length of taller office building.
So, L² = 155.7² + 148.6² - 2(155.7)(148.6)cos68°
L² = 24242.49 + 22081.96 - 46,274.04(0.3746)
L² = 46324.45 - 17334.56
L² = 28989.89
L = √28989.89
L = 170.26 ft
L ≅ 170 ft
b. How far apart are the apartment complex and the office building?
Using one of the lights, the distance between the buildings, d, the laser light(being the hypotenuse side) and the building (being the opposite side)form a right angled triangle.
So, using the 155.7 feet light at 36 angle,
cos36 = d/155.7
d = 155.7cos36
d = 155.7(0.8090)
d = 125.96 ft
d ≅ 126 ft

-29 -29
3x = 33
Divide by 3 on both sides.
x = 11!
Answer:
x is 11
Step-by-step explanation:
4X + 24 - X + 5 ≤ 62

A man earns 15000 in a month. if he spends 20% on food and 10% in his children's education.
a) what is his total expenditure?
b) how much does he save in a month?
Step-by-step explanation:
Total money=15000
food=20%
edu.=10%
food AMT=20% of 15000
=20/100*15000
= 3000
education AMT= 10/100*15000
=1500
savings = 15000-1500-3000
=Rs10500
total expenditure=1500+3000
=4500
