z= -400i - 44.5 what is the real part of z?

Answers

Answer 1

Answer:

-44.5

Step-by-step explanation:

The i part is imaginary.

The rest is real.

The real part is -44.5

Answer 2

Answer:

-44.5

Step-by-step explanation:

for a complex number

[tex]z=a+bi[/tex]

a is the real part

so in our case we have

[tex]z=-44.5-400i[/tex]

a = -44.5

so the real part is -44.5

Answers

Step-by-step explanation:

Diameter of base of cone = 30 cm .

Hence its radius = 30/2 cm = 15 cm

So , here the figure consists of a hemisphere and a cylinder . Now , here radius of the hemisphere is 15 cm . So , height of the Cylinder = ( 85 - 15 ) cm = 70 cm

→Volume of Cylinder :-

[tex]\large\boxed{\red{ Volume_{cylinder}=\pi r^2 h }}[/tex]

→ Volume = π r²h

→ Volume = 22/7 * ( 15 cm)² * 70 cm

Volume = 49,500 cm³ .

Volume of hemisphere :-

[tex]\large\boxed{\green{Volume_{hemisphere}=\dfrac{2}{3}\pi r^3}}[/tex]

→ Volume = ⅔ π r³

→ Volume = ⅔ * 22/7 * (15 cm)³

Volume = 10,607.14 cm³ 10 , 607 cm³ .

Hence Volume = ( 10 , 607 cm³ + 49,500 ) cm³ = 60,107 cm³

A Census Bureau report on the income of Americans says that with 90% confidence the mean income of all US households in a recent year was $57,005 with a margin of error of $742. This means that

Answers

Answer: d. the census bureau got the result 57,005 plus or minus 742 using a method that will capture the true median income 90% of the time when used repeatedly.

Step-by-step explanation:

No t-value has been included in this interval so it cannot be correctly labeled a confidence interval.

This invalidates options a to c.

Option d is therefore the correct answer because it states that the census bureau simply got those results above without claiming that the results constituted a confidence interval.

Suppose that an object is dropped from a height of h meters and hits the ground with a velocity of v meters per second. Then v = 19.6h. If an object is
dropped from a height of 35.9 meters, with what velocity does it hit the ground?
Round your answer to the nearest tenth.

Answers

Answer:

The object hits the ground with a velocity of 703.6 m/s.

Step-by-step explanation:

Evaluating Functions

The function that relates the velocity v in meters by second with the height h in meters an object was dropped from is:

v = 19.6h

We are required to evaluate the function above if we know the object was dropped from a height of h=35.9 meters.

Substituting in the equation:

v = 19.6*35.9

v = 703.64 m/s

Rounding to the nearest tenth:

The object hits the ground with a velocity of 703.6 m/s.

During an airplanes ascent, the plane reaches a horizontal distance from the airport of 1 km and then 7 km. The plane ascends at a slope of 2/3. Find the vertical distance (y) in feet that the plane traveled during the indicated spots

Answers

Answer:

The vertical distance in feet that the plane traveled was 4 Km

Step-by-step explanation:

The Slope of a Line

Suppose we know a line passes across points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The airplane ascent will be modeled with the equation of a line because we are given a constant slope of m=2/3. We also know the horizontal distances are x1=1 Km and x2=7 Km. Substituting in the formula above:

[tex]\displaystyle \frac{2}{3}=\frac{y_2-y_1}{7-1}[/tex]

Operating:

[tex]\displaystyle \frac{2}{3}=\frac{y_2-y_1}{6}[/tex]

Solving for y2-y1, we get the vertical distance traveled by the plane:

[tex]\displaystyle y_2-y_1=6*\frac{2}{3}=4[/tex]

Thus, the vertical distance in feet that the plane traveled was 4 Km

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing, and the end behavior when the following changes are made. Make sure to account for even and odd functions.

When f(x) becomes f(x) − 3
When f(x) becomes −2 ⋅ f(x)

Answers

Part A)
If f(x) - 3 is the new equation, it means there is a vertical translation of f(x) down 3 units. The y-intercept will decrease by 3 units. Areas of increasing on the function may be lessened as the function is being translated down 3 units. The areas of decrease will increase because the function is being translated down. End behaviour will not change from a translation as long as the function is continuous at each end, (not a finite function with end points). The evenness or oddness of f(x) will not change either.

Part B:
The y-intercept will be flipped horizontally about the x-axis and multiplied by 2. This will mean that if the y-intercept was positive, it will now be negative and vice versa. The increasing and decreasing regions of the graph will be flipped, so anywhere f(x) was positive will now be negative and vice versa. They will also be double what they were before because all values are multiplied by 2. The end behaviour will switch. If f(x) was from Quad1->Quad3 for example, it will now be Quad2->Quad4 because of the flip at the x-axis. The evenness and oddness of the function will not change seeing as the degree of f(x) is not affected.

A production process consists of consumption of the following material in Kgs:

a. 25.12% b. 29.12% C.38.15

Need solution with some explanation

Answers

Answer:

29.12%

Step-by-step explanation:

Given that :

A = 49

B = 50

C = 38

D = 60

E = 75

Total = (49 + 50 + 38 + 60 + 75) = 272

Pie chart % for each :

A = (49 / 272) * 360 = 64.85

B = (50 / 272) * 360 = 66.18

C = (38 / 272) * 360 = 50.29

D = (60 / 272) * 360 = 79.41

E = (75 / 272) * 360 = 99.26

Difference between C and D

(79.41 - 50.29) = 29.12%
