what is the sum of 3 - 2i and -5 + 6i?

Answers

Answer 1

Answer: -2 + 4i

Step-by-step explanation: I'm pretty sure you can't get the sum, but you can simplify the problem. All you need to do is combine like terms. -2i and 6i = 4i. 3 - 5 = -2.

Statement 3 ) 9x - 54 = 34

Reason 4 )  Addition Property of Equality

Reason 5 )  Division Property of Equality

Step-by-step explanation:

Let's me know if it wrong.

The missing statement and reason for the proof that the solution of 9(x  -  6)  +  41   =  75 is x = 88/9 are:

S3:  9x  -  54  =  34

R1:  Given

R2: Subtraction property of equality

R3: Distributive property

R4: Subtraction property of equality

R5: Division property of equality

The given equation is:

Statement1:   9(x  -  6)  +  41   =  75

Reason 1:  Given

Collect like terms

9(x - 6) =  75  -  41

Statement 2:  9(x  -  6)   =  34

Reason 2:  Subtraction property of equality

Expand the equation using distributive rule

Statement 3: 9x  -  54  =  34

Reason 3: Distributive property

Collect like terms in the equation 9x - 54  =  34

9x  =  34  +  54

Statement 4:  9x  =  88

Reason 4: Subtraction property of equality

Divide both sides by 9 in the equation 9x  = 88

Statement 5:  x  =  88/9

Reason 5: Division property of equality

Step-by-step explanation:

A drinking glass is in the shape of a cylinder. The volume of the glass is 2211.68 cubic centimeters, and its diameter is 16 centimeters. Find the height of the glass.

Round the answer to the nearest centimeter. Include the units in your typed answer.

Answers

Answer:

11cm

Step-by-step explanation:

diameter = 16, r = 8 (16÷2)

π = 3.142

V=πr2h

2211.68 = π x 8^2 x h

2211.68 = 3.142 x 64 x h

2211.68 ÷ 64 ÷ 3.142 = h

h = 10.9986

= 11 cm (round off to nearest cm)

To check and confirm

V=πr2h

3.142 x 64 (8^2) x 10. 9986 = 2211.68

Answers

Answer:

Step-by-step explanation:

A square with a side of 4cm will have a perimeter of 16cm (4+4+4+4).

If you put 2 on the other side of the rectangle, the perimeter will be: 6+1+6+1=14cm, which is smaller than the square's perimeter.

Step-by-step explanation:

Answer:  A)  I only

Explanation:

Relation I has each item in the domain map to exactly one item in the range. So any input leads to exactly one output. Therefore, we have a function here.

In contrast, relation II has the input x = 0 lead to multiple outputs (namely y = 8 and y = -1 at the same time). This indicates we do not have a function here.

Relation III is the same as as the previous one. This time the input x = -2 maps to both y = 1 and y = -7 at the same time. We don't have a function here either.

If you wanted, you can plot these points on the xy plane to see that relations II and III fail the vertical line test. You would need to plot each relation separately.

Fill in the missing number. % of 60 = 24

Answers

Answer:

40%

Step-by-step explanation:

Step 1: Set up an equation.

[tex]\frac{x}{100}(60)=24[/tex]

Step 2: Simplify both sides of the equation.

[tex]\frac{x}{100}(60)=24[/tex] [tex]\frac{60}{100}x= 24[/tex] [tex]\frac{3}{5}x=24[/tex]

Step 3: Multiply both sides by 5/3.

[tex]\frac{3}{5}x* \frac{5}{3}=24 * \frac{5}{3}[/tex] [tex]x = \frac{120}{3}[/tex] [tex]x = 40[/tex]

Therefore, the missing number is 40 to make 40% of 60 = 24.

Yo Rick Astley

X=16x

z=116

16x+112=128

360-128=232

232 divide by 2=116

Answer:

x = 9

z = 68

Step-by-step explanation:

For x, the top and bottom angles have the same value. To get x, you need to set up this equation: 12x + 4 = 112. Subtract 4 from itself and from 112. Your equation will then be 12x = 108. Divide 108 by 12, and then your answer is 9. So the value of x is 9.

For z, it's supplementary with the top angle. This means that the two angles combined add up to 180. So your question is: 112 + z = 180. Subtract 112 from 180, and then your answer is 68. So the value of z is 68.

A mustard seed has a mass of about 0.002 gram. A glass jar contains about 4.3602 x 10^4 A B C or D

Answers

Answer:

(2 x 10 ^-3) x (4 x 10 ^4)=8 x 10 ^1

Step-by-step explanation:

The mass of a single seed can be written as 0.002 = [tex]2*10^{-3}[/tex]

There are total of 4.3602 * 10 ⁴seeds in the jar

Total mass is the multiplication of these both numbers.

Since we want an estimate, we can use 4 instead of 4.3602 in the 2nd number.

The rule to multiply two numbers in scientific notation is:

[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d}[/tex]

So using this formula we multiply the 2 numbers and get answer as follows:

[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d} \\(2*10^{-3} )*(4*10^{4} )=(2*4)*10^{-3+4} \\=8*10^{1}[/tex]

The given transformation of reflection, rotation and translation are rigid transformation

The transformation that must take any point A to any point B are;

Rotation of 180° around the midpoint of segment ABReflection across the perpendicular bisectorTranslation by the directed line segment AB

Reason:

Question: The given quadrilaterals ABCD and A'B'C'D' are congruent

Required; To select all transformation that must take a point A to point B

Solution:  

Rotation of 180° around the midpoint of segment AB

A rotation of 180° about the midpoint of segment AB will change the places of points A and B

A(x, y) → R₁₈₀ → A'(-x, -y)

Let the coordinates of the origin be the midpoint of segment AB, and let (x, y) represent the coordinate of the point B(x, 0) we have;

∴ The coordinates of point A is A(-x, 0), which gives;

A(-x, 0) → R₁₈₀ → A'(x, 0) = point B

Therefore a rotation about the midpoint of AB must take point A to point B

Reflection across the perpendicular bisector

The reflection of a point (x, y) about y-axis gives a point (-x, y), therefore, we have;

A(-x, 0) → Reflection across the y-axis → A'(x, 0) = point B

Therefore, a reflection across the perpendicular bisector of the line AB must take the point A to point B

Translation by the directed line segment AB

A translation along the directed line segment AB of point A(-x, 0) 2·x units right gives;

A'(-x + 2·x, 0) = A'(x, 0) = Point B

Therefore, the transformations that must take any point A to any point B are;

Rotation of 180° around the midpoint of segment AB

Reflection across the perpendicular bisector

Translation by the directed line segment AB
