b. (a ⨯
b. · a = (a ⨯
b. · b =
We can verify that a ⨯ (a ⨯ b) is orthogonal to a. We can solve it in the following way.
To find the cross product a ⨯ b, we can use the formula:
a ⨯ b = |a| |b| sinθ n
where |a| and |b| are the magnitudes of vectors a and b, θ is the angle between a and b, and n is a unit vector perpendicular to both a and b, determined by the right-hand rule.
Using the given vectors a and b, we have:
|a| = √(4² + 5² + 0²) = √41
|b| = √(1² + 0² + 3²) = √10
To find the angle between a and b, we can use the dot product:
a · b = |a| |b| cosθ
4(1) + 5(0) + 0(3) = √41 √10 cosθ
Simplifying:
4 = √410 cosθ
cosθ = 4/√410
θ ≈ 77.09°
Now we can find the cross product using the formula:
a ⨯ b = |a| |b| sinθ n
a ⨯ b = √41 √10 sin(77.09°) n
Using the right-hand rule, we can determine that the unit vector n points in the negative z-direction, so n = -k, where k is the unit vector in the positive z-direction.
Thus, we have:
a ⨯ b = -√410 sin(77.09°) k
Evaluating this expression, we get:
a ⨯ b ≈ -0.667i + 1.777j - 3.617k
To verify that this vector is orthogonal to both a and b, we can take the dot product of a ⨯ b with a and b separately. If the dot product is zero, then the vectors are orthogonal.
a ⨯ b · a = (-0.667)(4) + (1.777)(5) + (-3.617)(0) = 0
a ⨯ b · b = (-0.667)(1) + (1.777)(0) + (-3.617)(3) = 0
Since both dot products are zero, we can conclude that the vector a ⨯ b is orthogonal to both a and b.
Note: The dot product of a vector and its own cross product is always zero, which can be used to verify that a ⨯ (a ⨯ b) is orthogonal to a. In this case, we have:
a ⨯ (a ⨯ b) = (4, 5, 0) ⨯ (-0.667, 1.777, -3.617)
= -17.07i - 6.248j - 12.005k
(a ⨯ (a ⨯ b)) · a = (-17.07)(4) + (-6.248)(5) + (-12.005)(0) = 0
Thus, we have verified that a ⨯ (a ⨯ b) is orthogonal to a.

Surface area of cylinder in terms of pi? Diameter of circle 3.4 inches. Height of rectangle 3 in
Surface area of the cylinder in terms of pi, given a diameter of 3.4 inches and a height of 3 inches, is [tex]28.36\pi[/tex] square inches.
To find the surface area of a cylinder in terms of pi, you need to add the areas of the top and bottom circles (which are identical) and the area of the curved lateral surface.
The formula for the area of a circle is [tex]A = \pi r^2[/tex], where r is the radius of the circle. Since the diameter of the circle is given as 3.4 inches, we can find the radius by dividing the diameter by 2:
r = 3.4 / 2 = 1.7 inches
Using this radius, the area of one circle is:
A = [tex]\pi (1.7)^2[/tex] = [tex]9.08\pi[/tex] square inches
Since the cylinder has two identical circles, the total area of both circles is:
2A = 2([tex]9.08\pi[/tex]) = [tex]18.16\pi[/tex] square inches
The lateral surface area of a cylinder can be found by multiplying the circumference of the base circle by the height of the cylinder. The formula for the circumference of a circle is C = 2πr, so the circumference of our circle is:
C =[tex]2\pi (1.7)[/tex]= [tex]3.4\pi[/tex] inches
The height of the cylinder is given as 3 inches, so the lateral surface area is:
A = Ch = ([tex]3.4\pi[/tex])(3) = [tex]10.2\pi[/tex] square inches
To find the total surface area of the cylinder, we add the areas of the two circles and the lateral surface:
Total surface area = 2A + A = [tex]18.16\pi + 10.2\pi[/tex] = [tex]28.36\pi[/tex] square inches
Therefore, the surface area of the cylinder in terms of pi, given a diameter of 3.4 inches and a height of 3 inches, is [tex]28.36\pi[/tex] square inches.

Amanda trains to run a marathon. She must follow a strict schedule to make sure she is ready for the race. She will start her training by running two miles the first week. She wants to run one fewer mile the next week, and then three more miles the week after that. She will continue this pattern during her entire training regimen. Write a sequence for the number of miles that Amanda will run the first 10 weeks of her training. Explain your reasoning.
The sequence for the number of miles that Amanda will run in the first 10 weeks of her training is
2, 1, 5, 0, 8, 3, 11, 5, 14, 7
What is a sequence?
A sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).
To find the sequence for the number of miles that Amanda will run in the first 10 weeks of her training, we need to first identify the pattern of increasing and decreasing miles she will run each week.
According to the given information, Amanda will start by running 2 miles in the first week.
In the second week, she will run one fewer mile, so she will run 2 - 1 = 1 mile. In the third week, she will run three more miles than she did in the first week, so she will run 2+3=5 miles.
In the fourth week, she will run two fewer miles than she did in the second week, so she will run 1 - 2 = -1 mile.
However, it doesn't make sense for Amanda to run a negative number of miles, so we can assume that she will take a rest week during the fourth week and not run any miles.
Then, she will resume her pattern of increasing and decreasing miles in the following weeks.
Therefore, we can write the sequence for the number of miles that Amanda will run in the first 10 weeks of her training as follows:
2, 1, 5, 0, 8, 3, 11, 5, 14, 7
To obtain this sequence, we applied the given pattern of running one fewer mile in the second week, followed by three more miles in the third week, and then repeating this pattern. We also accounted for the rest week during the fourth week by inserting a 0 in the sequence.
Hence, the sequence for the number of miles that Amanda will run in the first 10 weeks of her training is
2, 1, 5, 0, 8, 3, 11, 5, 14, 7

he standard unit of measurement for angles is the degree, with 360 degrees being one entire circle.

The right response is "mZC > mZS".
The right side of the figure is longer than the left side if RT is bigger than BA. Angle X is greater than angle W, and angle Z is greater than angle Y as a result.
Angles C and S will have the same measure if the triangles are identical because they are matching angles (they are in the same place in each triangle). We are unsure, nevertheless, whether the triangles are comparable.

Anton borrowed some money from his parents. Every week he earned $23 from doing chores. After 12 weeks he had $200 after paying back his parents.
a) how much did anton borrow from his parents
b) write an equation to represent the amount of money,y,anton will have after x weeks
Answer:
a. $76.00
b. y = 23x - 76
Step-by-step explanation:
a. If Anton earned $23 every week for twelve weeks, his total revenue would be 23 (12) = 276 dollars. He only had $200 after paying his parents back, though, so that means if you take away the $200 leftover money he got (after paying his parents back) from the $276 he earned over the 12 weeks, you'll get 276 - 200 = he borrowed $76.00 from his parents.
b. Anton is earning $23 every week, so the money, y, that he'll have after x weeks is y = 23x. But since he borrowed $76 from his parents, that much money should be subtracted from his money-making equation, leaving us with y = 23x - 76. Hope this was helpful!

Α) 2π
B) 4
C) 8
D) 16
The radius of the circle is approximately 16 units.
Define the term Circle identities?The Circle identities refer to a set of fundamental identities in trigonometry that relate the six trigonometric functions of an angle in a right-angled triangle.
Here, ∠PQO = 45° So, ∠QPO = 45° (because OP = OQ radius)
So, central angle is 90°
The formula of arc length of a circle is :
arc length = [tex]\frac{central angle}{360} * (2\pi r)[/tex] ; here, the radius of the circle is r
Substituting the values we get:
27 = (90/360) x (2πr)
r = 54/π
Therefore, the radius of the circle is approximately 17.1 units.
by using radius we can find any area in circle.
So, nearby option D. is correct 16 units.

what is unitary method ?To answer mathematical issues involving proportional relationships between two or more quantities, one uses the unitary method. It is a technique for determining the value of one unit depending on the value of another, in other words. In several disciplines, including mathematics, physics, economics, and engineering, the unitary technique is frequently utilized. Finding the value of a single unit of a given quantity and using that value to calculate the value of a desired number of units is what this process entails.
given
The initial amount of water plus the water that has been added over time equals the total amount of water in the pond at any one time. We can apply the following formula because the rate of water addition is constant at 28 liters per minute:
W = 600 + 28T
where W is the pond's total volume of water (measured in liters), and T is the passing of time (in minutes).
T = 12 can be used in the equation to determine how much water was in the pond overall after 12 minutes:
W = 600 + 28T
W = 600 + 28(12) (12)
W = 600 + 336
W = 936

Graph the image of T(10, – 2) after a reflection over the x-axis.
Answer:
To graph the image of T(10, -2) after a reflection over the x-axis, you simply need to flip the point vertically so that it lies on the opposite side of the x-axis.
The x-coordinate of the point will stay the same, and the y-coordinate will change sign.
Starting with the point T(10, -2), reflect it over the x-axis to obtain the image point T'(10, 2), which is 10 units to the right of the y-axis and 2 units above the x-axis.
So the graph of T(10, -2) after a reflection over the x-axis is the point T'(10, 2), as shown in the following diagram:

The probability of an event happening is determined by probability: P(A) = f / N.
Probability and odds are related, but probability determines what the odds are.
So, the formula for probability is:
P(E) = Favourable events/Total events
Now, insert values:
Babby can get:
TT, HH, HT, TH
Abby will only get: H or T
Then,
P(E) = Favourable events/Total events
P(E) = 3/4
Therefore, Babby has a 3/4 probability of obtaining the same number of heads as Abby.

or
-1.6f - 15
Step-by-step explanation:
-2.3f + 0.7f - 12 - 3 =
-8/5f - 15
or
-1.6f - 15
Answer:
[tex] \sf \: -1.6f - 15 [/tex]
Step-by-step explanation:
Now we have to,
→ Simplify the given expression.
The expression is,
→ -2.3f + 0.7f - 12 - 3
Let's simplify the expression,
→ -2.3f + 0.7f - 12 - 3
→ (-2.3f + 0.7f) - 12 - 3
→ (-1.6f) + (-12 - 3)
→ -1.6f + (-15)
→ -1.6f - 15
Hence, the answer is -1.6f - 15.
