Here are some points. What are the coordinates of G, H, and I after a rotation about the origin 90 degrees clock-wise?
Answer:
[tex]G' = (3,1)[/tex]
[tex]H' = (-4,0)[/tex]
[tex]I' = (-2,-3)[/tex]
Step-by-step explanation:
Given
See attachment for points G, H and E
Rotation: 90 degrees clock-wise
Required
Determine the coordinates after rotation
From the attachment:
[tex]G = (-1,3)[/tex]
[tex]H = (0,-4)[/tex]
[tex]I = (3,-2)[/tex]
When a point (x,y) is rotated 90 degrees clockwise, the new point is: (y,-x)
So, we have:
[tex]G = (-1,3)[/tex]
[tex]G' = (3,1)[/tex]
[tex]H = (0,-4)[/tex]
[tex]H' = (-4,0)[/tex]
[tex]I = (3,-2)[/tex]
[tex]I' = (-2,-3)[/tex]
Solve. 8 - 2d = c 4c + 3d = 2 c=4 d = -6 C=-4 d = 6 C=4 d = 6 C=-4 d = -6
Answer:
c = -4 d = 6
Step-by-step explanation:
8 - 2d = c 4c + 3d = 2
4(8 - 2d) + 3d = 2
32 - 8d + 3d = 2
32 - 5d = 2
-5d = -30
d = 6
8 - 2(6) = c
8 - 12 = -4 = c

James, Ryan and Jill share £120 in the ratio 3:2:1.
Find out how much each person recieves.
Answer:
James = £60, Ryan = £40 and Jill = £20
Step-by-step explanation:
James - 3, Ryan - 2 and Jill - 1
3 + 2 + 1 = 6
£120 / 6 = 20
Times 20 by each of the three numbers (3, 2 and 1)
3 x 20 = £60 (James)
2 x 20 = £40 (Ryan)
1 x 20 = £20 (Jill)
Answer:
James gets £60
Ryan gets £40
Jill gets £20
Step-by-step explanation:
Add up the ratio which would be 6 then divide it by the original sum which is £120 so the answer would be 20. You would then multiply 20 by each number so 20x3= 60. 20x2= 40. 20x1=20
All these should add up to your original sum and if they do you know you've done it right!
Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. Given that the investment yields 2.7% simple interest annually, how big was the initial deposit?
a. $2,524.50
b. $4,024.03
c. $4,250.00
d. $11,404.88
Answer:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.Solving our equation:
P = 6774.5 / ( 1 + (0.027 × 22)) = 4250P = $4,250.00The principal investment required to get a total amount, principal plus interest, of $6,774.50 from simple interest at a rate of 2.7% per year for 22 years is $4,250.00I do exams and quizzes if your interested!The initial deposit amount is $4,250.00.
Given that,
The worth of an investment is $6774.50The time period is 22 years. The rate of interest is 2.7%.Based on the above information, the calculation is as follows:
We know that
[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]
Now
Investment worth = P + SI
= P + 0.594P
= 1.594P
So,
1.594P = 6774.50
P = $4,250
Therefore we can conclude that the initial deposit amount is $4,250.00.

12 + 5/3 b + 1 1 − 18 = 20
Answer: b = 9
Step-by-step explanation:
Given
12 + 5/3b + 11 - 18 = 20
Combine like terms
(12 + 11 - 18) + 5/3b = 20
5 + 5/3b = 20
Subtract 5 on both sides
5 + 5/3b - 5 = 20 - 5
5/3b = 15
Divide 5/3 on both sides
5/3b / (5/3) = 15 / (5/3)
b = 9

A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their weights?
Answer:
[tex]123.19890025 kg^2[/tex]
Step-by-step explanation:
We are given that
Standard deviation, s=11.0995 kg
Sample size, n=10
We have to find the variance of their weights.
We know that
Variance=[tex](standard\;deviation)^2[/tex]
Using the formula
The variance of their weights
=[tex](11.0995)^2[/tex]
=[tex]123.19890025 kg^2[/tex]
Hence, the variance of their weights=[tex]123.19890025 kg^2[/tex]

θ
rounded to 1 DP.
Answer:
56.9°
Step-by-step explanation:
Assuming you mean a and b as the legs of a right triangle and θ as the bigger angle in a right triangle, we can work out easily that
cos θ = 6/11
so θ ≈ 56.9°(to 1 d.p.)

The equation y = 1125(1.034)" can be used to approximate the number of cell phone users
who live in a certain city over time, where a represents the number of years after 2000.
Which of the following statements is true?
A
the rate of growth is 34%
B
there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%
D
In the year 2005, there were more than 1350 cell phone users.
Answer: B
there were 1125 cell phone users in 2000.
Step-by-step explanation:
The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.
So the initial number of cell phone users in 2000 was 1125.

find the length of side x in simplest radical form with a rational denominator 60 30 x 2
Answer:
x = √3
Step-by-step explanation:
Looking at the given triangle,
x is the adjacent side while 2 represents the hypotenuse side.
Now, from trigonometric ratios, we know that;
Adjacent/hypotenuse = cos θ
The angle here will be 30°
Thus;
x/2 = cos 30°
We are told to find x in simplest radical form with a rational denominator.
Thus means we will use the surf value of the angle.
cos 30° in surd form = (√3)/2
Thus;
x/2 = (√3)/2
x = 2 × (√3)/2
x = (√3)/1
x = √3
