Find the unit vector in the same direction as v = -5i - 9j
According to the given data the unit vector in the same direction as v is
u = (-5/ sqrt(106))i - (9/ sqrt(106))j.
What is meant by unit vector?A unit vector is a vector that has a length or magnitude of 1. In other words, a unit vector is a vector that has been normalized, or scaled down to have a length of 1 while still pointing in the same direction as the original vector.
According to the given information:To find the unit vector in the same direction as v = -5i - 9j, we first need to calculate its magnitude.
The magnitude of v is given by:
|v| = sqrt((-5)^2 + (-9)^2) = sqrt(25 + 81) = sqrt(106)
Now we can find the unit vector in the same direction as v by dividing v by its magnitude:
u = v / |v| = (-5i - 9j) / sqrt(106)
Therefore, the unit vector in the same direction as v is:
u = (-5/sqrt(106))i - (9/sqrt(106))j
Note that the unit vector has a magnitude of 1 and points in the same direction as v.

Which ordered pair represents the point labeled C?
The x axis starts at negative 3, with tick marks every one unit up to positive 3. The y-axis starts at negative 3, with tick marks every one unit up to three. Point A is left two units and up one unit from the origin. Point B is right two units and up one unit from the origin. Point C is down two units from the origin. Point D is left one unit and down one unit from the origin.
(−2, 1)
(−1, −1)
(0, −2)
(2, 2)
The ordered pair that represents the point labeled C is (0, -2). Option (C) is the correct answer.
We can start by considering the given information about the coordinate axes. The x-axis starts at negative 3 with tick marks every one unit up to positive 3, and the y-axis starts at negative 3 with tick marks every one unit up to 3. The origin is the point where the x-axis and y-axis intersect, and it has coordinates (0, 0).
Next, we are given information about four points labeled A, B, C, and D. Points A and B are both one unit up and two units to the left or right of the origin, respectively. Point D is one unit to the left and one unit down from the origin.
Finally, we are asked to determine the coordinates of point C. We know that point C is labeled as being two units down from the origin, which means that it has a y-coordinate of -2.
To determine the x-coordinate of point C, we can observe that it lies on the y-axis, which means that it has an x-coordinate of 0 (since the y-axis intersects the x-axis at x = 0). Therefore, the ordered pair that represents point C is (0, -2), which matches option (C).

pencils in the case. If each box of pencils weighs
2.5 ounces, what is the weight, in pounds, of the
case of wooden pencils?
Answer:
10 pounds
Step-by-step explanation:
First, we need to determine the total weight of the pencils in ounces:

The plane's new altitude after 0.05 hours is approximately 9.9 kilometers.
How to solvewe'll use the sine function to find the vertical distance of the plane
sin(angle) = vertical_distance / total_distance
vertical_distance = sin(angle) × total_distance
To find the sine of 11°, we need to convert the angle to radians. We know that 180° = π radians:
11° × (π radians / 180°) ≈ 0.191986 radians
Now, we can find the vertical distance:
vertical_distance = sin(0.191986) × 25 km
vertical_distance ≈ 0.190809 × 25 km
vertical_distance ≈ 4.77022 km
Finally, we'll add this vertical distance to the initial altitude to find the new altitude:
h = initial_altitude + vertical_distance
h = 5.1 km + 4.77022 km
h ≈ 9.87022 km
Rounding to the nearest tenth of a kilometer:

A 21
B 42
C 63
D 84
The number of students surveyed speak Spanish or Haitian Creole at home are 42.
What is percentage?
Percentage is a part of a whole.
Let the number of students who speak Spanish be S and the number of students who speak Haitian Creole be H. We can set up the following equations based on the given information:
24% of 175 students speak Spanish
So, S = 0.24 x 175
And 12% of 175 students speak Haitian Creole
So, H = 0.12 x 175
We need to obtain the number of students who speak either Spanish or Haitian Creole,
So, S + H - (number of students who speak both languages).
percentage who speak both languages = 100% - (24% + 12%) = 64%
So, the number of students who speak both languages is 0.64 x 175 = 112
Now, we are obtaining the number of students who speak either Spanish or Haitian Creole:
S + H - (number of students who speak both languages) = (0.24 x 175) + (0.12 x 175) - 112
= 42
Therefore, the answer is B) 42, which represents the number of students who speak Spanish or Haitian Creole at home.

Volume of square-base container =3 456 cm³ 2.3.1 Determine the length of the side of the square-base container. Formula: Volume = side2 x height
Answer:
mark me brilliant
Step-by-step explanation:
We can use the given formula to solve for the length of the side of the square-base container:
Volume = side^2 x height
where side is the length of the side of the square base, and height is the height of the container.
We are given that the volume of the container is 3,456 cm³. However, we do not know the height of the container.
To find the length of the side of the square base, we need to first determine the height of the container. We can do this by rearranging the formula:
height = Volume / (side^2)
Plugging in the values we know:
height = 3456 cm³ / (side^2)
We know that the container has a square base, so the length of each side of the base is the same. Therefore, we can write:
Volume = side^2 x side x height
Substituting the expression we found for height:
Volume = side^2 x side x (3456 cm³ / side^2)
Simplifying:
Volume = 3456 cm³ = side^3
Taking the cube root of both sides:
side = ∛3456 cm = 18 cm
Therefore, the length of the side of the square-base container is 18 cm.

Step-by-step explanation:
Hector is in the 32% tax bracket. He acquired 10,000 shares of stock in Eclipse Corporation three years ago at a cost of $100 per share. In the current year, Hector received a payment of $225,000 from Eclipse Corporation in exchange for 2,000 of his shares in Eclipse. Eclipse has E & P of $975,000. Hector has a capital loss carryover of $50,000 in the current tax year. Assume that Hector has no capital losses and taxpayers in the 32% tax bracket are subject to the long-term capital gains and qualified dividends tax rate of 15%.
The $225,000 payment from Eclipse Corporation is a qualifying stock redemption for tax purposes.
Hector may use $fill in the blank eb9ae1fb8010fec_1

what is Hector's tax liability ?
To define means to provide a clear and precise explanation of what something means or refers to. It involves breaking down a concept or term into its key components and providing a thorough understanding of its meaning. A definition can be used to clarify or explain the meaning of a word, idea, or concept to ensure a common understanding between people.
To calculate Hector's tax liability, we need to first determine his gain on the redemption.
Hector received $225,000 in exchange for 2,000 shares, which means he received $112.50 per share (225,000/2,000). His cost basis in the 2,000 shares redeemed is $100 per share, so his gain on the redemption is $12,500 per share ($112.50 - $100 = $12.50).
Hector's total gain on the redemption is therefore $25,000 ($12,500 x 2,000 shares).
Since Hector has a capital loss carryover of $50,000, he can use up to $25,000 of it to offset his gain on the redemption. This will result in a tax liability of 15% on the remaining $25,000 gain, which is $3,750 ($25,000 x 0.15).
Hector's income tax liability will also include the tax on his other income, such as wages or interest income. Assuming he has no other deductions or credits, his total income tax liability will be $64,000.
Therefore, the answers are:
Hector may use $25,000 of the capital loss carryover to offset the gain on the redemption.
His income tax liability is $64,000.
