The notation used for a vector pointing into the point is X.
A quantity with a magnitude and direction is called a vector. A vector quantity will be identified in these annotations by a bold letter (such as the electric field vector E). Vectors appear graphically as straight arrows. The magnitude of the vector is commonly represented by the length of the arrow, and both the arrow and the vector point in the same general direction.
Arrows are drawn on the page to represent vectors in the page's plane. Typically, circles with an X engraved on them are used to represent vectors that enter the screen's plane. A vector that deviates from the screen's plane is often represented by circles with dots in the center.

The domain of h(z) would be (-8,3).

What are the domain and range of a function?
The domain is the set of all x-values that can be used to make the function "work" and produce actual y-values.
A function's range is the variety of conceivable y-values (minimum y-value to maximum y-value)
For the function f(x):
Domain: (-4,7)
Range: (2,9)
The function f(x+4) is equal to 1 (f(x+4)).
This shows, inputs: -4, outputs: 1
Domain of f(x+4):
add -4 to the Domain values of f(x)
Domain:(-4-4,7-4)=(-8,3)
Range of f(x+4):
Multiply the range values of f(x) by 1
Range: (1*2,1*9)= (2,9)
Find, where the point (4,8) would be moved:
add -4 to 4, and multiply 8 by 1

A factory produces 270000 000 sweets every
week. How many sweets does the factory
produce in a year? Give your answer in
standard form
The factory produced 1.404 x 10⁶ sweets in a year
How to calculate the number of sweets the factory produce in a year?
Standard form is a way of writing very large numbers or very small numbers in a simpler form. It is also called scientific notation
Given that: The factory produces 270000000 sweets every
week.
To know how many sweets the factory produces in a year, we will multiply the quantity produced in a week by 52 since there are 52 weeks in a year. Thus:
Number of sweet in a year = Weekly production x 52
= 270000000 x 52 = 14040000000 sweets
To express 140400000000 in standard form, we will move the position of the decimal point to the back of the first number(1) and take note of the number of steps we take to get there. The number of steps will then be used as the power of 10:
14040000000 = 1.404 x 10⁶
Therefore, the number of sweets produced by the factory in a year in standard form is 1.404 x 10⁶ sweets

Suppose g(x) = f(x + 2) - 3. Which statement best compares the graph of g(x)

• C. The graph of g(x) is shifted 2 units right and 3 units
up.
• D. The graph of g(x) is shifted 2 units left and 3 units down.
We deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit up in the graph of g(x). The best choice is C.
Describe a graph.A diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.
Right-shift a function
Inside the function's argument, subtract. For instance, is essentially moved b units to the right.
You go to the right while subtracting from the parameter of the function.
Accordingly, f(x) is moved two units to the right in g(x) = f(x - 2).
also to advance a function
Outside of the function, add. For instance, is essentially shifted up units.
G(x) = f(x - 2) + 3 hence says that f(x) is shifted up by 3 units.
Overall, then, using two transformations, we deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit upswing in the graph of g(x).
Therefore, choice C is right.

a car is traveling at 57 mi/h before it enters into a skid. the drag factor of the road surface is 1.1, and the braking efficiency is 100%. how long might the average skid mark be to the nearest tenth of a foot?
The average skid mark for the car is 98.5 feet.
The average skid mark can be calculated by the formula -
S = ✓30Dfn, where s is speed of car, D is skid distance, f is drag factor and n is braking efficiency. Keep the values in formula to calculate the value of D.
57 = ✓30 × D × 1.1 × 1
Performing multiplication on Right Hand Side of the equation
57 = ✓D × 33
Taking square on both sides of the equation
D = 57² ÷ 33
Taking square on numerator on Right Hand Side of the equation
D = 3249 ÷ 33
Performing division on Right Hand Side of the equation
D = 98.45 feet
Rounding to the nearest tenth of a foot
D = 98.5 feet
Hence, the average skid mark is 98.5 feet.

in the figure, h II o find the value of x and y
Answer:
y = 119
30 =x
Step-by-step explanation:
61 and y are same side interior angles and they add to 180
61+y = 180
y = 180-61
y = 119
y and 6x-61 are vertical angles and they are equal
y = 6x-61
119 = 6x-61
Add 61 to each side
119 + 61 = 6x
180 = 6x
Divide each side by 6
180/6 = x
30 =x
Answer:
y = 119°
x = 30°
Step-by-step explanation:
We know that if two lines are parallel, the co - interior angles are added up to 180°°.
Accordingly,
y + 61 = 180
y = 180 - 61
y = 119°
Also, we know that, vertically opposite angles are equal to each other.
y = 6x - 61
119 = 6x - 61
Now, we have to make x the subject.
For that, first, add 61 for both sides.
119 + 61 = 6x
180 = 6x
Now, divide both sides by 6.
30° = x

suppose goop purchases 150 gallons of raw material. what is the probability that they will run out of raw material?
The probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.
We have following information,
the demand for the polymer is distributed normally .
Mean (μ) = 250 gallons and Standard deviations (σ) = 125 gallons
Selling price of poymer = $25 per gallons
cost price of raw material for polymer= $ 10 per gallons
Salvage value = $(-5)/ gallon
Now, Using the formula for normally distributed sample,
Z = ( X - μ ) /σ
where , X---> sample mean
μ ----> population mean
σ----> standard deviations
Z -----> Z-value
from question it is clear X = 150
putting all the values of variables in above formula we get, Z = ( 150-250)/125 = -100/125
= - 0.8
(-0.8) value of z = 0.21 = 21% , the value of z is measure from normal distribution table.
They will run out of raw material if demands exceds this quantity or
Probability ( out of stock ) = 1 - 0.21 = 0.79 = 79%
So, the probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.

11 Sand costs $98.90 per tonne.
This cost includes a tax of 15%.
Calculate the amount of tax paid per tonne of sand.
The amount of tax paid per tonne of sand is $14.835 as the sand costs $98.90 per tonne.
What is meant by percentage?In mathematics, a percentage is a value or ratio expressed as a fraction of 100.
The term percent is derived from the Latin per centum, which means "hundred" or "by the hundred." The sign for "percent" comes from the Italian expression per cento, which means "for a hundred." The "per" was frequently shortened as "p." and finally disappeared entirely. The "cento" was reduced to two circles divided by a horizontal line, from which the present "%" symbol was derived.
Given,
The cost of one Tonne of sand=$98.90
The tax on one Tonne=15%
The amount of tax per Tonne of sand is,
=(15/100)×98.90

The equation of line parallel to the given line is found as y = -6x + 13.
What is meaning of the term parallel slopes?A line's slope is similar to the slopes of adjacent parallel lines, therefore m1 = m2. Additionally, the equations of a parallel line could be determined by applying the formulas; (y−y1)=m(x−x1) ( y − y 1 or by y = mx + c.The equation of the line is-
y = -6x + 1
The second line is parallel to the above line, thus the slopes of both the line are equal.
m1 = m2 = -6
The new line also passes from the point (1, 7)
(x1, y1) = (1,7)
Thus, the equation of the line will be calculated as-
y - y 1 = m2(x - x1)
y - 7 = -6(x - 1)
y - 7 = -6x + 6
y = -6x + 13
