a) Two vectors are proportional then compa b = compa a
b) Two vectors are parallel when proja b = proja a
A vector is a mathematical object with both magnitude and direction. In this problem, we have two vectors, a and b, which are assumed to be nonzero
(a) For two vectors a and b, the dot product (also known as the scalar product or inner product) is a scalar quantity that measures the extent to which the vectors are pointing in the same direction. The dot product of two vectors is defined as
=> compa b = ||a|| ||b|| cos(θ), where ||a|| and ||b|| are the magnitudes of the vectors and θ is the angle between them.
Hence,
=> compa b = compb a
if and only if the vectors are equal or parallel, meaning they have the same direction or are pointing in opposite directions.
(b) The projection of a vector onto another vector is the vector that points in the same direction as the second vector and has the same magnitude as the component of the first vector that lies in that direction. The projection of a vector a onto a vector b is given by
=> proja b = (compa b / compb b) b.
Since the dot product is commutative, it follows that
=> proja b = proj b
if and only if the vectors are equal.

Binomial Distribution - Algebra 2B
A local bakery sells the freshest bread in town. In fact, 65% of customers who come into this store buy bread. What is the probability that at least 3 customers out of the first 6 will buy bread?
So the probability that at least 3 customers out of the first 6 will buy bread is 0.7929 or about 79.29%.
To determine the appropriate probability, we may utilise the binomial distribution's cumulative distribution function (CDF). The likelihood that the number of successful occurrences in a specified number of independent trials is less than or equal to a specific value is given by the binomial distribution's CDF.
Let X represent the proportion of the first 6 clients who purchase bread. Then, X has a binomial distribution with n = 6 and p = 0.65 as its parameters. One less than the likelihood that fewer than three consumers will purchase bread results in the chance that at least three will:
P(X >= 3) = 1 - P(X < 3)
Using a cumulative distribution function of the binomial distribution, we can calculate P(X < 3) as:
P(X < 3) = CDF(2, n=6, p=0.65)
Using a binomial calculator or a programming library that implements the CDF of the binomial distribution, we find that P(X < 3) = 0.2071. Therefore, the desired probability is:
P(X >= 3) = 1 - P(X < 3) = 1 - 0.2071 = 0.7929

The area between the graph of f and the x-axis on the interval [-8, 0] is 4608 square units.
How big is the region between the graph?The two-dimensional region enclosed by the function's graph and the x-axis is referred to as the region between the graph and the x-axis. Calculating the definite integral of the function over the specified interval and deducting the area below the x-axis, if any, will yield the area of this region.
There are two sections to the graph of f(x) = |x3 - 64|: a parabolic section and a linear section. The area between the graph of f and the x-axis is just the absolute value of the definite integral of f(x) over [-8, 0] because the graph of f(x) on the interval [-8, 0] is below the x-axis and contains negative values.
We must first get the antiderivative of f(x) before we can determine the definite integral, which may be accomplished by utilising partial fraction decomposition.
The antiderivative of f(x) = x⁴ - 64 is:
F(x) = (x⁴)/4 + 64x
The definite integral of f(x) over [-8, 0] is:
Area = F(0) - F(-8) = (0⁴)/4 + 64(0) - ((-8)⁴)/4 - 64(-8) = (8⁴)/4 + 64(8) = 4096 + 512 = 4608

50% of the kittens are black in colour.
Total number of kittens = 6
Out of these, 3 are black, 2 are grey, and 1 is white.
The Latin word "per centum," which meaning "by the hundred," was the source of the English word "percentage." Fractions with a denominator of 100 are called percentages. In other words, it is a relationship where the value of the entire is always assumed to be 100.
A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.
Now, percentage of kittens that are black:
(Total number of Black Kittens/Total number of kittens) x 100 %

Let C R2 be the circle with radius 6 centered at the origin. Let F : R2 → R2 be the vector field defined by F(x, y) = (7x, 1 1). Find the flux of F coming out of the circle through the curve C.
The flux of F coming out of the circle C is 126π.
The flux of a vector field, F, out of a surface, S, is given by the formula
Flux = ∮F • n ds,
where n is a unit normal vector to the surface S.
In this case, the surface S is the circle C with radius 6 centered at the origin and the vector field F is given by F(x, y) = (7x, 11). We can use Green's Theorem to find the flux from the circle C. The equation for the circle is x2 + y2 = 36. Differentiating this equation with respect to x and y gives us the unit normal vector, n = (x/6, y/6).
Plugging these values into the flux formula, we get
Flux = ∮F • n ds = ∮ (7x, 11) • (x/6, y/6) ds
= ∮ 7x2/6 + 11y/6 ds
= (7/6) ∮ (x2 + y2) ds
= (7/6) * Area of C
= (7/6) * π * 36
= 126π.

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To calculate how much Charlotte would make in a week in which she made $1575 in sales
we first need to calculate her commission:
Commission = 30% × $1575
= $472.50
Total earnings = Guaranteed salary + Commission
= $500 + $472.50
= $972.50
Therefore, Charlotte would make $972.50 in a week in which she made $1575 in sales.
To calculate how much Charlotte would make in a week if she made x dollars in sales, we can use the same method.
Her commission would be:
Commission = 30% ×x
And her total earnings would be:
Total earnings = Guaranteed salary + Commission
= $500 + 0.3x
So, if Charlotte made x dollars in sales, she would make $500 + 0.3x in total earnings for the week.

A taxi driver uses this formula to work out fares, Fare = £2. 50 + £0. 90 x miles
Use the formula to work out:
a. The fare for a 9-mile journey.
give your answer in pounds
ASAP PLEASE
The fare for a 9-mile journey can be calculated using the formula Fare = £2.50 + £0.90 x miles. To find the fare for a 9-mile journey, we just need to substitute 9 for miles in the formula:
Fare = £2.50 + £0.90 x 9
Fare = £2.50 + £8.10
Fare = £10.60
So, the fare for a 9-mile journey would be £10.60.
It's important to understand how the formula works in order to correctly use it. The first part of the formula, £2.50, is a fixed cost that is added to the fare regardless of the distance traveled. This could represent things like the cost of hiring the taxi, the driver's time, and any other fixed expenses that the taxi company incurs.
The second part of the formula, £0.90 x miles, is the variable cost that is added to the fare depending on the distance traveled. This could represent things like the cost of fuel, wear and tear on the vehicle, and any other expenses that the taxi company incurs as a result of traveling a certain distance. By multiplying the distance traveled by the cost per mile, £0.90, the formula calculates the total variable cost for the journey.
When these two costs are added together, the formula gives the total fare for the journey. In this case, for a 9-mile journey, the total fare would be £10.60.

A tower stands on top of a hill. From a point on the ground that is 148 meters directly east of a point directly under the tower, the angle of elevation to the bottom of the tower is 18 degrees. From the same point, the angle of elevation to the top of the tower is 34 degrees. Find the height of the tower.
Answer:
62.2 m
Step-by-step explanation:
From 148m away at ground level, the angel of elevation to the tower base is 18 degrees. Imagining this as a right angled triangle, if considering the angle of 18 degrees, 148m is the adjacent and the opposite is the height of the hill:
tanA=opposite/adjacent
tan18=opposite/148
opposite = 57.8357059295m
From 148m away at ground level, the angel of elevation to the tower top is 34 degrees. Imagining this as a right angled triangle, if considering the angle of 34 degrees, 148m is the adjacent and the opposite is the height of the hill+the tower:
tanA=opposite/adjacent
tan34=opposite/148
opposite = 120.062515998m
Knowing the height of the hill and tower is 120.062515998m and the height of the hill is 57.8357059295m, we can say the height of the tower is the difference:
120.062515998 - 57.8357059295 = 62.2268100685 m
yy x cos y da, d is bounded by y 0, y x 2, x 1
First, we need to set up the bounds for the integral. The lower and upper limits of the integral are x = 1 and y = x2, respectively. The integral ∫x1 [cos(x2)dx] is equal to -2/3.
Next, we can substitute the upper limit of the integral into the integrand to get:
∫x1 [cos(x2)dx]
Then, we can use integration by parts to solve the integral. We let u = cos(x2) and dv = dx. This gives us:
du = -2x sin(x2) dx
and
v = x
This gives us:
∫x1 [cos(x2)dx] = x cos(x2) - ∫x1 [-2x sin(x2)dx]
Now, we can solve the second integral. We let u = x2 and dv = -2 sin(x2)dx. This gives us:
du = 2x dx
and
v = -cos(x2)
This gives us:
∫x1 [-2x sin(x2)dx] = -x2 cos(x2) - ∫x1 [2x dx]
Finally, we can solve the last integral. We let u = x and dv = 2 dx. This gives us:
du = dx
and
v = x2
This gives us:
∫x1 [2x dx] = x3 + c
where c is the constant of integration.
Putting it all together, we get that
∫x1 [cos(x2)dx] = x cos(x2) - x2 cos(x2) - x3 - c
Substituting in the limits of the integral, we get that
∫x1 [cos(x2)dx] = 1 - x2 - x3 - c
Since the lower limit of the integral is x = 1, we have that
∫x1 [cos(x2)dx] = -x2 - x3 - c
Substituting in the upper limit of the integral, we get that

The compound inequality for the graph shown above include the following:
x < -4.
x ≤ 5.
What is a number line?In Mathematics, a number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values that are placed at equal intervals along its length.
Since the first point is at -4 and the arrow points to the left of the number line, it represents the less than (<) inequality symbol and should be written as x < -2.
Additionally, the second point is located at 5 and the arrow points to the left of the number line with a shaded circle, it represents the greater than (>) inequality symbol and should be written as x ≤ 5.

students at city middle school rent a popcorn machine for a school event.the event will last 8 hours.two companies rent popcorn machines. company A charges $14 pr delivery fee and $8 per hour. company B uses the cost function:C(x)=10x + 10.which is the better value
The company that has a better value is: company A.
What is the slope-intercept form?In Mathematics, the slope-intercept form of a line can be calculated by using this linear equation:
y = mx + c
Where:
x represents the number of hours.y represents the total fee.m represents the slope of a line.c represents the y-intercept of a line.Since the total fee that is being charged by company A is denoted by C(x) and it charges $14 per delivery fee and $8 per hour, an equation that models this situation is given by;
C(x) = 8x + 14
When hours, x = 8 hours, the total fee is given by:
C(8) = 8(8) + 14
C(8) = $78.
For company B, the total fee is given by:
C(x) = 10x + 10
C(8) = 10(8) + 10
C(8) = $90.

Answer:
Subtract the amount of £1 coins from 50p coins:
256-172 = 84
84/3 coins = 28 people paid with 3 coins.
172 people paid using £1 coins
172 + 28 = 200 total people
percent who used 3 coins = 28/200 = 0.13 x 100 = 14% so the answer is 14%
