Thus, z2 in polar form is: z2 = 5√2 * (cos(-π/4) + i * sin(-π/4)).

To write z1 = 4 + 4i and z2 = 5 - 5i in polar form, we need to express them in terms of their magnitude (r) and argument (θ).

For z1 = 4 + 4i:

The magnitude (r) of z1 is given by:

|r1| = sqrt(Real^2 + Imaginary^2) = sqrt(4^2 + 4^2) = sqrt(16 + 16) = sqrt(32) = 4√2

The argument (θ) of z1 can be calculated using the arctan function:

θ1 = arctan(Imaginary / Real) = arctan(4 / 4) = arctan(1) = π/4 radians

Thus, z1 in polar form is:

z1 = 4√2 * (cos(π/4) + i * sin(π/4))

For z2 = 5 - 5i:

The magnitude (r) of z2 is given by:

|r2| = sqrt(Real^2 + Imaginary^2) = sqrt(5^2 + (-5)^2) = sqrt(25 + 25) = sqrt(50) = 5√2

The argument (θ) of z2 can be calculated using the arctan function:

θ2 = arctan(Imaginary / Real) = arctan(-5 / 5) = arctan(-1) = -π/4 radians

Thus, z2 in polar form is:

z2 = 5√2 * (cos(-π/4) + i * sin(-π/4))

Function g(r) = -(I + 8)³ has a restricted domain, since the cube of any real number can be either positive or negative, but not both. Specifically, in this case, the domain of g(r) is restricted to the set of real numbers where (I + 8)³ is non-negative.

The equation of the tangent to the curve x = 5 sin(t), y = t^2 + t at the point (0,0) is y = 5x.

To find the equation of the tangent line, we need to find the derivative of y with respect to x. Using the chain rule, we get:

dy/dx = dy/dt * dt/dx

To find dt/dx, we can take the reciprocal of dx/dt, which is:

dt/dx = 1/(dx/dt)

dx/dt = 5 cos(t), so:

dt/dx = 1/(5 cos(t))

Now, to find dy/dt, we take the derivative of y with respect to t:

dy/dt = 2t + 1

So, putting it all together, we get:

dy/dx = dy/dt * dt/dx = (2t + 1)/(5 cos(t))

At the point (0,0), t = 0, so:

dy/dx = 1/5

So the equation of the tangent line is:

y = (1/5)x + b

To find the value of b, we plug in the coordinates of the point (0,0):

0 = (1/5)(0) + b

b = 0

Therefore, the equation of the tangent line is: y = (1/5)x

A value of r greater than 0.40 indicates a stronger correlation than 0.40.

The correlation coefficient, denoted as "r," measures the strength and direction of the linear relationship between two variables. The value of r ranges from -1 to 1. When the absolute value of r is closer to 1, it indicates a stronger correlation. In this case, a value of r greater than 0.40 suggests a stronger positive correlation than 0.40.

This means that as one variable increases, the other variable tends to increase as well, and the relationship between the variables is more pronounced. For example, if the correlation coefficient is 0.60, it indicates a stronger positive correlation than 0.40. Similarly, if the correlation coefficient is 0.90, it indicates an even stronger positive correlation. On the other hand, if the correlation coefficient is negative, such as -0.60 or -0.90, it indicates a stronger negative correlation.

A 15 ¾ in. board is cut in a single cut from a 38 ¼ in board. The saw cut takes 3/8 in.  21 ¾ inches of the 38 ¼ inch board is left.

To find out how much of the 38 ¼ inch board is left after cutting, follow these steps:
1. Determine the total length of the cut: The cut takes 3/8 inch and removes a 15 ¾ inch board, so the total length of the cut is 15 ¾ inches + 3/8 inch.
2. Convert mixed numbers to improper fractions: 15 ¾ = (15 × 4 + 3)/4 = 63/4; 38 ¼ = (38 × 4 + 1)/4 = 153/4
3. Add the improper fractions: (63/4) + (3/8) = (63/4) + (3/8 × 2/2) = (63/4) + (6/8) = (126/8) + (6/8) = 132/8 = 16 ½ inches
4. Subtract the cut length from the original board length: (153/4) - (132/8) = (153/4) - (16 ½ × 4/4) = (153/4) - (66/4) = 87/4 = 21 ¾ inches
After cutting, 21 ¾ inches of the 38 ¼ inch board is left.

(a) The value of m∠1 in the intersecting chords is 31.5⁰.

(b) The value of m∠2 in the intersecting chords is 139⁰.

(c) The value of m∠3 in the intersecting chords is 41⁰.

(d) The value of m∠4 in the intersecting chords is 93⁰.

(e) The value of m∠5 in the intersecting chords is 69.5⁰.

(f) The value of m∠6 in the intersecting chords is 69.5⁰.

The value of the missing angles is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

The measure of angle 1 is calculated as follows;

arc angle opposite 72.5⁰ = 2 x 72.5⁰ = 145⁰

missing arc angle = 360 - ( 145⁰ + 139)

missing arc angle = 76⁰

m∠1 = ¹/₂ ( 139 - 76) (exterior angle of intersecting secants)

m∠1 = ¹/₂ (63) = 31.5⁰

The measure of angle 5 is calculated as;

m∠5 = ¹/₂ (139⁰)

m∠5 = 69.5⁰ (interior angle of intersecting secants)

The measure of angle 2 is calculated as;

m∠2 = 2 x m∠5 (angle at center is twice angle at circumference)

m∠2 = 2 x 69.5 = 139⁰

The measure of angle 6 is calculated as;

m∠6 = ¹/₂ (139⁰)

m∠6 = 69.5⁰ (interior angle of intersecting secants)

The measure of angle 3 is calculated as follows;

m∠3 = ¹/₂ ( (360 - 139) - 139) (exterior angle of intersecting secants)

m∠3 = ¹/₂ (221 - 139)

m∠3 = 41⁰

The measure of angle 4 is calculated as follows;

θ = 180 - (72.5 + m∠6)

= 180 - (72.5 + 69.5)

= 180 - 142

= 38

Each base angle of angle 2 = ¹/₂ (180 - 139) = 20.5⁰

= 38 - 20.5⁰

= 17.5⁰

m∠4 = 180 - (17.5⁰ + m∠5) (sum of angles in a triangle)

m∠4 = 180 - (17.5 + 69.5)

m∠4 = 93⁰

Answer:

Because the cake pan holds 234 in.³ and the four round cake pans hold a total of around 226.19 in.³

Edit: I multiplied the diameter as the radius. Answer has now been corrected.

Step-by-step explanation:

To solve this, we need to figure out how much each batter can hold.

For this one, the formula is simple. we multiple everything together to get the volume.

13×9×2=234 in.³

For this one, you will have to use pi or π. A round cake pan is most likely a cylinder. Therefore, we will use the cylinder volume formula, which is:

V=πr²h

V=π(3)²(2)

V=π(9)(2)

V=18π

V is around 56.5486678 or 56.55. However, if you are using 3.14 for π, you will get something else, 56.52.

But remember that this is only one cake pan. There are 4 of them. So, we can simply multiple the number by 4. To help this be more accurate, I will go back to 18π first.

V=18π(4)

V=72π

=226.194671058

or around 226.19.

If you are using 3.14, just multiply by 3.14 instead of π. You will get a very similar result, with only a minor difference. It all depends on which one you are using.

Good luck with your homework! If this is correct, please give me brainliest :)

Answer:

Step-by-step explanation:

You want to know the volumes of a 13×9×2 inch rectangular cake pan, and of four 2-inch deep round cake pans 6 inches in diameter.

The volume of the rectangular cake pan is given by ...

  V = LWH

  V = (13 in)(9 in)(2 in) = 234 in³

The volume of four round cake pans with diameter d is given by ...

  V = 4×(π(d/2)²h) = πd²h

  V = π(6 in)²(2 in) = 72π in³ ≈ 226.2 in³

The rectangular pan holds more cake batter.

The cake pan holds 234 in³, and the four round pans hold 226.2 in³.

Let's start by defining some variables:

P0 = 151000      // initial population in 2013

r = 0.05         // constant annual growth rate

t = 7            // number of years from 2013 to 2020

The exponential model for the population can be written as follows:

y = P0 * (1 + r)^t

Substituting in the values we get:

y = 151000 * (1 + 0.05)^7

y ≈ 209749

Therefore, the exponential model that represents the population of the city t years after 2013 is y = 151000 * (1 + 0.05)^t, and the estimated population in 2020 is about 209,749.

Note that the result is an estimation, and can be affected by various factors, such as migration and mortality rates, that are not accounted for in the model.

Ms. Brown left at 9:00 am

Her plane landed 1 hour and 23 minutes later.

What time does her plane land?

We Take

9:00 + 1:23 = 10:23 am

So, her plane landed at 10:23 am

We start by using the chain rule to find the derivative of w with respect to t: dw/dt = (∂w/∂x) (dx/dt) + (∂w/∂y) (dy/dt) + (∂w/∂t)

dw/dt = 320 when t = 1.

To find ∂w/∂x, we treat y and t as constants and differentiate w = x^2 y^2 t with respect to x:

∂w/∂x = 2xy^2 t

To find ∂w/∂y, we treat x and t as constants and differentiate w = x^2 y^2 t with respect to y

∂w/∂y = 2x^2 yt

To find ∂w/∂t, we treat x and y as constants and differentiate w = x^2 y^2 t with respect to t:

∂w/∂t = x^2 y^2

Substituting the given values x = 4t and y = 2t, we get:

∂w/∂x = 2(4t)(2t)^2 t = 32t^4

∂w/∂y = 2(4t)^2 (2t) t = 64t^4

∂w/∂t = (4t)^2 (2t)^2 = 64t^4

Using these values, we can write:

dw/dt = (∂w/∂x) (dx/dt) + (∂w/∂y) (dy/dt) + (∂w/∂t)

= (32t^4)(4) + (64t^4)(2) + (64t^4)

= 320t^4

Finally, substituting t = 1, we get:

dw/dt = 320(1)^4 = 320

Therefore, dw/dt = 320 when t = 1.

The probability that a randomly chosen student is taking tech given that they are taking art is 50%.

To find the probability that a randomly chosen student is taking tech given that they are taking art, we need to use conditional probability. We can use the formula:

P(Tech | Art) = P(Tech and Art) / P(Art)

We know that 62 students are taking both tech and art, so P(Tech and Art) = 62. To find P(Art), we need to subtract the number of students who are only taking tech or only taking art from the total number of students:

P(Art) = (74 - 62) + (112 - 62) + 62 = 124

Therefore, we have:

P(Tech | Art) = 62 / 124 = 0.5

So the probability that a randomly chosen student is taking tech given that they are taking art is 50%.

In summary, we can use conditional probability to find the probability that a randomly chosen student is taking tech given that they are taking art.

The radius of convergence of the power series 12"x" n! n=1 is infinity.To determine the radius of convergence, we use the ratio test.

Let a_n be the nth term of the series, then a_n = 12"x" n! / n. Applying the ratio test, we have:

lim as n approaches infinity of |a_{n+1}/a_n| = lim as n approaches infinity of |12"x" (n+1)! / (n+1)| / |12"x" n! / n|

= lim as n approaches infinity of |12"x"| * (n+1) / n

= |12"x"| * lim as n approaches infinity of (n+1) / n

Since lim as n approaches infinity of (n+1) / n = 1, the limit simplifies to |12"x"|. The ratio test tells us that the series is convergent when |12"x"| < 1 and divergent when |12"x"| > 1. Since |12"x"| is always positive, the series is convergent for all values of x, which means the radius of convergence is infinity.

Answer:

See below

Step-by-step explanation:

Slope-intercept form of an equation of line:

[tex]y = mx + c[/tex]  —— eq(i)

Where:

c = y-intercept

  = y-value for which the corresponding x-value is 0

  = [tex]-1[/tex] (From the provided table)

m = slope
   = [tex]\frac{rise}{run}[/tex]

   = [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] —- eq(ii)

Choose any two sets of coordinates and then substitute in eq(ii). I chose:

[tex](3, 8)[/tex] as [tex](x_{1}, y_{1})[/tex]

[tex](4, 11)[/tex] as [tex](x_{2}, y_{2})[/tex]

   = [tex]\frac{11 - 8}{4 - 3}[/tex]

   = [tex]\frac{3}{1}[/tex]

∴ m = [tex]3[/tex]

Substituting the values of c and m in eq(i):

[tex]y = (3)x + (-1)[/tex]

∴ Equation for the function

[tex]y = 3x - 1[/tex]

The zeros of the function G(t) are given by t = -1 + √(20.25g) and t = -1 - √(20.25g).

What is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.

To find the zeros of the function G(t), we need to find the values of t that make G(t) equal to zero. So, we start by setting G(t) to zero and solving for t:

G(t) = 0

(t+1)2 - 20.25g = 0 [substituting G(t) in place of 0]

(t+1)2 = 20.25g [adding 20.25g to both sides]

t+1 = ±√(20.25g) [taking the square root of both sides]

t = -1 ± √(20.25g) [subtracting 1 from both sides]

So, the zeros of the function G(t) are given by t = -1 + √(20.25g) and t = -1 - √(20.25g).

The complementary error function is a function commonly used in communications and signal processing to compute the tail probabilities of Gaussian random variables. It is defined as:

Q(x) = 1/√(2π) ∫x to ∞ e^(-t^2/2) dt

where x is a real number. Geometrically, Q(x) represents the area under the standard normal probability density function to the right of x. This means that Q(x) gives the probability that a standard normal random variable takes on a value greater than x.

The complementary error function is related to the error function, erf(x), which is defined as:

erf(x) = 2/√(π) ∫0 to x e^(-t^2) dt

In fact, Q(x) can be expressed in terms of erf(x):

Q(x) = 1/2 erfc(x/√2)

where erfc(x) is the complementary error function.

The travel time for a college student travelling between her home and her college is uniformly distributed between 40 and 70 minutes. The probability that the college student will finish her trip in 60 minutes or less is c. 0.6667.

To calculate the probability, we'll use the information about the travel time uniformly distributed between 40 and 70 minutes.
Step 1: Identify the range of possible travel times.
The range is from 40 to 70 minutes, so the total range is 70 - 40 = 30 minutes.
Step 2: Identify the desired range (60 minutes or less).
Since we want to find the probability that the trip takes 60 minutes or less, the desired range is 60 - 40 = 20 minutes.
Step 3: Calculate the probability.
Since the distribution is uniform, the probability is simply the ratio of the desired range to the total range. Therefore, the probability is 20/30 = 2/3 = 0.6667.

Answer:Usually you should just use these two rules:

T(x)+T(y) = T(x+y)

cT(x) = T(cx)

Where T is your transformation (in this case, the scaling matrix), x and y are two abstract column vectors, and c is a constant.

If these two rules work, then you have a linear transformation :)
