What is the distance between z1 = 5 - 2i and z2 = 8 + i?
3√2
13.3
2√3
18
Answer:
d=2√10
Step-by-step explanation:
The distance between the two points will be given by:
d=√[(x-x1)^2+(y-y1)^2]
point z1=(3-2i) has the coordinates of (3,-2)
point z2=(5-8i) has the coordinates of (5,-8)
thus the distance between them will be:
d=√[(-8-(-2)²+(5-3)²)]
d=√[(-6)²+2²]
d=√(36+4)
d=√40
d=2√10
Answer:
3√2
Step-by-step explanation:
distance formula: d = √(a₁ - a₂)² + (b₁ - b₂)²
a = x, b = y
d = √(x₁ - x₂)² + (y₁ - y₂)²

Form a polynomial whose zeros and degree are given.
Zeros: -2, 2, 9; degree: 3
Type a polynomial with integer coefficients and a leading coefficient of 1 in the box below.
Answer:
the polynomial is: [tex]\mathbf{x^3-9x^2-4x+36=0}[/tex]
Step-by-step explanation:
We need to form a polynomial whose zeros are:
-2,2,9
We can write them as: x=-2, x=2 and x=9
x+2=0, x-2=0 , x-9=0
(x+2)(x-2)(x-9)=0
Now multiplying all terms:
[tex](x(x-2)+2(x-2))(x-9)=0\\(x^2-2x+2x-4)(x-9)=0\\(x^2-4)(x-9)=0\\x^2(x-9)-4(x-9)=0\\x^3-9x^2-4x+36=0[/tex]
So, the polynomial is: [tex]\mathbf{x^3-9x^2-4x+36=0}[/tex]

Find the value of y
Will give brainliest
And brainless lol
Answer:
155
Step-by-step explanation:
- because of the angle rules, (6x+1) = (2x+17)
- with this, you can now solve to get x = 4
- also because of the angle rules, y = 180 - (2x+17)
- replace the x with 4 and calculate and you'll get y = 155
what is 5 1/2 plus 5 1/4
Answer 10.75
......................................
Answer:
10 and 3/4
Step-by-step explanation:
For the fractions, get a common denominator (bottom number): 1/2=2/4
So 2/4 plus 1/4 equals 3/4 and 5+5 equals ten.
10+3/4=10 3/4
Decimal form: 10.75
A corporation worth 40 million is expected to grow 8% per year compounded annually for 5 years. (A) find the future value to the nearest million. (B)
Answer:
$56 million
Step-by-step explanation:

A car travels at a constant speed.
What is the car's speed between checkpoints, expressed as a unit rate?
Use the information given in the picture.
Answer:
Step-by-step explanation:
Checkpoint A-> time being 1:00pm total miles driven being 120 and
checkpoint B-> time being 3:00pm and the total miles being 208
The distance between two checkpoint A and B is 208 - 120 = 88 miles
Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours
We need to find car speed between the checkpoints
We know Distance = speed * time
Speed = 44 miles per hour
Answer:
The answer is 1 miles

A cylindrical mass has a radius of 5 cm and a height of 6 cm. If the mass of the cylinder is 900 grams, what is the density of the cylinder?
Approximately 1.9 grams per cubic centimeter.
First you calculate the size of the cylinder in centimeters by taking the area of the base and multiplying it by the height, and then you divide the mass of the cylinder by the volume.

Given the definitions of f(x) and g(x) below, find the value of (gof)(9).
f(x) = -2x + 14
g(x) = 2x2 - 6x – 2
Answer:
The value of (gof)(9)=54
Step-by-step explanation:
We are given:
[tex]f(x) = -2x + 14\\g(x) = 2x^2 - 6x - 2[/tex]
We need to find (gof)(9).
To find (gof)(9) first we will find g(f(x)) and then put x=9
Finding g(f(x))
By putting value of f(x) into g(x) i.e
[tex]g(f(x))=2(-2x+14)^2-6(-2x+14)-2[/tex]
Now putting x=9
[tex]g(f(9))=2(-2(9)+14)^2-6(-2(9)+14)-2\\g(f(9))=2(-18+14)^2-6(-18+14)-2\\g(f(9))=2(-4)^2-6(-4)-2\\g(f(9))=2(16)+24-2\\g(f(9))=32+24-2\\g(f(9))=54[/tex]
so, the value of (gof)(9)=54

In a large human population, cranial length is approximately normally distributed with a mean of 185.6 mm and a standard deviation of 12.7 mm. What is the probability that a random sample of size 10 from this population will have a mean less than than 180? a. 0.0174 b. 0.1357 c. 0.0823 d. -1.39
Answer:
The correct option is c
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 185.6 \ mm[/tex]
The standard deviation is [tex]\sigma = 12.7 \ mm[/tex]
The sample size is n = 10
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{ 12.7}{\sqrt{ 10 } }[/tex]
=> [tex]\sigma_{x} = 4.016[/tex]
Generally the probability that a random sample of size 10 from this population will have a mean less than than 180 is mathematically represented as
[tex]P(X < 180 ) = P(\frac{ X - \mu }{\sigma_{x} } < \frac{180 - 185.6}{4.016} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 180 ) = P(Z < - 1.394 )[/tex]
From the z table the area under the normal curve to the left corresponding to -1.394 is
[tex]P(X < 180 ) = P(Z < - 1.394 ) = 0.081659[/tex]
=> [tex]P(X < 180 ) = 0.0823[/tex]
