Answer:
(B) Write Negative 3 and one-third as Negative StartFraction 10 over 3 EndFraction, and find the reciprocal of StartFraction 4 over 9 EndFraction as StartFraction 9 over 4 EndFraction. Then, rewrite Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction as Negative StartFraction 10 over 3 EndFraction times StartFraction 9 over 4 EndFraction. The quotient is Negative 7 and StartFraction 6 over 12 EndFraction = Negative 7 and one-half.

hello! I've tried looking up videos on how to do this, but I'm very confused as there aren't any that look quite like the one I was given. If someone could help, I'd appreciate that so much!
I can figure out the roots in order of increasing angle measure, so no worries about that, I know how to do that:)
Answer:
Step-by-step explanation:
The genral form of a complex number in rectangular plane is expressed as z = x+iy
In polar coordinate, z =rcos ∅+irsin∅ where;
r is the modulus = √x²+y²
∅ is teh argument = arctan y/x
Given thr complex number z = 6+6√(3)i
r = √6²+(6√3)²
r = √36+108
r = √144
r = 12
∅ = arctan 6√3/6
∅ = arctan √3
∅ = 60°
In polar form, z = 12(cos60°+isin60°)
z = 12(cosπ/3+isinπ/3)
To get the fourth root of the equation, we will use the de moivres theorem; zⁿ = rⁿ(cosn∅+isinn∅)
z^1/4 = 12^1/4(cosπ/12+isinπ/12)
When n = 1;
z1 = 12^1/4(cosπ/3+isinn/3)
z1 = 12^1/4cis(π/3)
when n = 2;
z2 = 12^1/4(cos2π/3+isin2π/3)
z2 = 12^1/4cis(2π/3)
when n = 3;
z2 = 12^1/4(cosπ+isinπ)
z2 = 12^1/4cis(π)
when n = 4;
z2 = 12^1/4(cos4π/3+isin4π/3)
z2 = 12^1/4cis(4π/3)
Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 3 units long. Point C is on the line x = -1. If the area of triangle ABC is 6 square units, then find a possible y-coordinate of point C. Options: 5 6 7 8
Answer:
The possible y-coordinate of point C is 6
Step-by-step explanation:
The coordinate of a point is given by (x,y) where x is the horizontal distance from the origin on the x axis and y is the vertical distance from the origin.
Given Segment AB is on the line y = 2 and is 3 units long and Segment AB is on the line y = 2 and is 3 units long. The area of triangle ABC is 6 square units.
The area of a triangle = 1/2 × base × height
6 = 1/2 × 3 × height
height = (2 × 6) / 3 = 4 units
Since point C is perpendicular to line y = 2, they coordinates is either 2 + 4 = 6 or 2 - 4 = -2
The coordinate of point C is either (-1, 6) or (-1, -2)
The coordinate of point C is either (-1, 6) or (-1, -2)
Area of triangles and coordinatesThe formula for calculating the area of a rectangle is expressed as;
A = 0.5bhwhere:
b is the base of the triangleh is the height of the triangle;Get the height of the triagle:
6 = 0.5(3)h
6 = 1.5h
h = 6/1.5
h = 4 units
Since point C is perpendicular to line y = 2, the y-coordinates will be either (2 + 4) = 6 or (2 - 4) = -2
Hence the coordinate of point C is either (-1, 6) or (-1, -2)

so, 12/25 = .48 * 100 = 48%
Hope this helps!
Answer:
The answer to this question is 48% is broken
Please help! Correct answers only please!
A student was conducting a study to determine how many mini chocolate chip cookies would fit in a plastic sealed container. He used random packing to find the following.
Using the collected data above what would be a reasonable rough estimate of a ratio of how many cubic inches per cookie?
A. 2.2 in^3/cookie
B. 0.45 in^3/cookie
C. 17.82 in^3/cookie
D. 23.76 in^3/cookie
Answer: (A) [tex]2.2\text{ in}^3/\text{cookie}[/tex] .
Step-by-step explanation:
From the given table , the dimension of the container for the 90cookies = 11 inch x 6 inch x 3 inch
Then, the volume of the container would be [tex]11\times6\times3= 198 \ in^3[/tex]
Then, the ratio of cubic inches per cookie would be
[tex]=\dfrac{\text{Volume of container}}{\text{Number of cookies in it}}\\\\=\dfrac{198}{90}\\\\=2.2\text{ in}^3/\text{cookie}[/tex]
So, the the ratio of cubic inches per cookie would be [tex]2.2\text{ in}^3/\text{cookie}[/tex] .
Hence, the correct option is (A) [tex]2.2\text{ in}^3/\text{cookie}[/tex] .

The volume of a box containing 15 identical cubes is 295245cu.m. Find the edge of the cube.
Answer:
Edge length of the cube = 27 m
Dimensions of the box is length = 135 m, width = 81 m, height = 27 m
Step-by-step explanation:
The box contains 15 identical cubes therefore, we have
Edge length of cube = Side, s, of cube
15 × s³ = 295245 m³
∴ s³ = 295245/15 = 19683 m³
s = ∛19683 = 27 m
Hence the edge length of the cube = 27 m
The dimension of the box is length = 5 × 27 = 135 m
Width = 3 × 27 = 81 m
height = 27 m.

Please answer correctly !!!!!!!! Will mark brianliest !!!!!!!!!!!
Answer:
x=6
Step-by-step explanation:
h(x) = -( x-2)^2 +16
We want when h(x) = 0
0 = -( x-2)^2 +16
Subtract 16 from each side
-16 = -( x-2)^2 +16-16
-16 = -( x-2)^2
Divide by -1
16= ( x-2)^2
Take the square root of each side
±sqrt(16) = sqrt(( x-2)^2 )
±4 = x-2
Add 2 to each sdie
2 ±4 = x-2+2
2+4 = x 2-4 =x
6 =x -2 =x
since time cannot be negative
x=6
Can anybody help me solve for surface area? The formula is the sum of the areas of the faces.
I will mark as brainliest ASAP!
Answer:
Surface area of the given prism = 63 square feet
Step-by-step explanation:
Surface area of the given triangular prism = Area of two triangular bases + Area of three vertical rectangles
Area of triangular bases = 2[[tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]] (Since the bases of this prism are right triangles)
= 3 × 3
= 9 square ft
Area of one vertical rectangular face = (Length × Width)
= (3 × 6)
= 18 square feet
Area of all vertical sides = 3 × 18 = 54 square feet
Total surface area = 9 + 54 = 63 square feet

[tex][6^{7} ]^{3} \\(6)^7^*^3\\6 ^{21} \\[/tex]
Answer:
B
Step-by-step explanation:
When solving exponents with parenthesis around the base + sub exponent, always multiply the two exponents. Basically, when the two exponents are right next to each other, you multiply them. When you multiply 7 and 3, you get 21; therefore, the answer is 6 to the power of 23.
1 / cosec A -1 - 1 / cosec A + 1
Answer:
Given expression is [tex]\frac{1}{\text{cosec}A-1}-\frac{1}{\text{cosecA+1}}[/tex] = 2tan²A
We have to prove this identity.
[tex]\frac{1}{\text{cosec}A-1}-\frac{1}{\text{cosecA+1}}=\frac{(\text{cosecA+1})-(\text{cosecA-1})}{(\text{cosecA-1})(\text{cosecA+1})}[/tex]
= [tex]\frac{(\text{cosecA}-\text{cosecA})+(1+1)}{cosec^2A-1}[/tex]
= [tex]\frac{2}{cosec^{2}A-1}[/tex]
= [tex]\frac{2}{cot^{2}A}[/tex] [From the identity, (cosec²A - 1) = cot²A]
= 2tan²A [From the identity, cotA = [tex]\frac{1}{\text{tan}A}[/tex]]
Hence the given equation is proved.
5 – 6x = 8x + 17 and simplify [tex]\frac{-6}{7}[/tex]
Answer:
x = -6/7
Step-by-step explanation:
5 – 6x = 8x + 17
-5 - 5 Subtract 5 from both sides
-6x = 8x + 12
-8x - 8x Subtract 8x from both sides
-14x = 12 Divide both sides by -14
x = -12/14 Simplify
x = -6/7

2x + 10 < 5x + 1
Answer:
x>3
Step-by-step explanation:
2x + 10 < 5x + 1
Add -5x and -10 on both sides of the inequality.
2x + 10 -10 -5x < 5x + 1 -5x -10
2x -5x < 1 -10
Subtract like terms.
-3x < -9
Multiply -1 and reverse the inequality.
3x>9
Divide 3 into both sides of the inequality.
3x/3>9/3
x>3
Answer: x > 3
Step-by-step explanation: Put your x's together on the left side of the inequality by subtracting 5x from both sides to give you -3x + 10 < 1.
Next, put your numbers together on the right by
subtracting 10 from both sides and we have -3x < -9.
To get x by itself, divide both sides by -3, but watch out.
If you multiply or divide both sides of an inequality by a negative,
you must switch the direction of the inequality sign.
Please give this idea your full attention.
Even the most advanced algebra students will sometimes forget to
switch the direction of the inequality sign when multiplying or
dividing both sides of an inequality by a negative.
So we have x > 3 as our answer.
