Answer:
(14 , -7)
Step-by-step explanation:
terminal points: A (-6,3) B (4,-2)
u = x₁ + i y₁ u = -6 + i3
v =x₂ + iy₂ = 4 - i2 2v = 8 - i4
2v - u = (8 - i4) - (-6 + i3) = 14 -i7
Resulting terminal point: (14 , -7)
Position vectors u and v have terminal points of (-6, 3) and (4, -2), respectively. Find the resulting terminal point of 2v - u.

A rectangular water tank is 80 m long, 50 m wide and 60 m height. If the
depth of water in the tank is 45 m, find the volume of water required to
completely fill the tank?*
A)240,000cm3
B)60,000cm3
C)180,000cm3
D)120,000cm3
Answer: 2
Step-by-step explanation:
80 x 50 x 60 is volume of tank
240000
Water is already filled to 45 so volume up to that is
80x 50 x 45 = 180000
Subtract to find the difference needed to fill tank
240000 - 180000 = 60000
The volume of water to completely fill the tank is A) 240,000cm³.
What is volume?Volume is defined as the amount of three-dimensional space occupied by some close object.
We know the volume of a cuboid is (Height×Width×Length).
Given a rectangular water tank is 80m long, 50m wide and 60m in height and the depth of the water is 45m.
To obtain the volume of water we have to take 45m as the height or we can think of the height of the tank is 60m but water can only be filled up to 45m.
∴ The volume of the water is (80×50×45) m³.
= 180,000 m³.

Step-by-step explanation:
Solve the equation by graphing. - x2 = 8x + 20
Answer: No real solutions.
Step-by-step explanation: −x2=8x+20
Step 1: Subtract8x+20 from both sides.
−x2−(8x+20)=8x+20−(8x+20)
−x2−8x−20=0
For this equation: a=-1, b=-8, c=-20
−1x2+−8x+−20=0
Step 2: Use quadratic formula with a=-1, b=-8, c=-20

Work out 77 % of 775.66 m Give your answer rounded to 2 DP.
Answer:
597.25 m
Step-by-step explanation:
We need to find 77% of 775.66 m.
It can be calculated as follows :
[tex]77\%\times 775.66\\\\=\dfrac{77}{100}\times 775.66\\\\=597.25\ m[/tex]
So, 77% of 775.66 m is equal to 597.25 m.
A circular light fixture has a radius of 20 centimeters.what is the circumference of the light fixture
Answer:
[tex]\boxed {\boxed {\sf 40 \pi \ cm, 125.6 \ cm, or \ 125.6637061 \ cm}}[/tex]
Step-by-step explanation:
Circumference can be found by multiplying the diameter of the circle by pi.
[tex]c= \pi d[/tex]
We are given the radius, which is 20 centimeters. We need the diameter, which is twice the radius.
[tex]d= 2r[/tex]
[tex]d= 2(20 \ cm)[/tex]
[tex]d= 40 \ cm[/tex]
Substitute the diameter into the formula. There are many ways to calculate circumference, so I included a few options.
1. In Terms of Pi
If we solve in terms of pi, we leave π in the answer.
[tex]c=\pi ( 40 \ cm)[/tex]
[tex]c= 40 \pi \ cm[/tex]
2. Using 3.14 as Pi
[tex]c=\pi ( 40 \ cm)[/tex]
Substitute 3.14 in for pi.
[tex]c= (3.14)(40 \ cm)[/tex]
[tex]c=125.6 \ cm[/tex]
3. Using 3.14159 as PI
[tex]c=\pi ( 40 \ cm)[/tex]
Use the pi button on a calculator.
[tex]c= 125.6637061 \ cm[/tex]
The circumference of the light fixture is 40π, 125.6 cm, or 125.6637061 cm

In a certain state, a survey of 600 workers showed that 35% belonged to a union. Find the 95% confidence interval of true proportion of workers who belong to a union.
Answer:
The 95% confidence interval of true proportion of workers who belong to a union.
(0.29657 , 0.40343)
Step-by-step explanation:
Explanation:-
Given sample size 'n' = 600
Given sample proportion p = 35% or 0.35
The 95% confidence interval of true proportion of workers who belong to a union.
[tex](p^{-} -Z_{0.05} \sqrt{\frac{pq}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{pq}{n} } )[/tex]
[tex](0.35 -1.96\sqrt{\frac{0.35 X0.65}{600} } , 0.35 + 1.96\sqrt{\frac{0.35 X 0.65}{600} } )[/tex]
( 0.35 - 1.96 (0.02726) , 0.35 + 1.96 (0.02726)
(0.35 - 0.05343 , 0.35 + 0.05343)

Calculate the correlation coefficient, r, for the data below.
This question is incomplete, the complete question is;
Calculate the correlation coefficient, r, for the data below.
X = -10 -8 -1 -4 -6 -7 -5 -3 -2 -9
Y = -15 -13 4 -4 -7 -11 -6 -2 1 -13
Answer: the correlation coefficient, r, for the data is 0.9896
Step-by-step explanation:
Given the data in the question;
correlation coefficient r = ?
we know that, C_Coeff is;
r = [ (Zn(∑xy) - (∑x)(∑y) ] / [ √[( n∑x² - (∑x)²) ( n∑y² - (∑y)²)] ]
so ;
X Y X² Y² XY

-8 -13 64 169 104
-1 4 1 16 -4
-4 -4 16 16 16
-6 -7 36 49 42

-3 -2 9 4 6
-2 1 4 1 -2
-9 -13 81 169 117
∑ -55 -66 385 806 536
now we substitute our values into the formula
r = [ (10×536 - (-55)(-66) ] / [ √[( 10×385 - (-55)²) ( 10×806 - (-66)²)] ]
r = 1730 / √( 825 × 3704 )
r = 1730 / √3055800
r = 1730 / 1748.0846
r = 0.9896
Therefore the correlation coefficient, r, for the data is 0.9896
