Since this is a right triangle, we can use trig functions

cos theta = opp / hyp

cos 27 = BC / 15

15 cos 27 = BC

13.36509 = BC

a) \(a(t) = t -2.5\)

b) \(x(t) = \frac{1}{6}t^3 -\frac{5}{4}t^2 +2t +2.5\\\)

Part a:

Acceleration is just the derivative of velocity. In this case, we are given how the velocity, \(v(t)\), is defined. If we take the derivative of \(v(t)\) that'll be our acceleration.

Recall:

\(\frac{\mathrm{d}}{\mathrm{d}x}(x^n) = nx^{n -1}\\\)

\(\frac{\mathrm{d}}{\mathrm{d}x}(f(x) +g(x)) = \frac{\mathrm{d}}{\mathrm{d}x}(f(x)) +\frac{\mathrm{d}}{\mathrm{d}x}(g(x))\\\)

\(\frac{\mathrm{d}}{\mathrm{d}x}(a \cdot f(x)) = a \cdot \frac{\mathrm{d}}{\mathrm{d}x}(f(x))\\\)

Let \(a(t)\) be the acceleration. Solving for \(a(t)\):

\(v(t) = 0.5t^2 -2.5t +2 \\ \frac{\mathrm{d}}{\mathrm{d}t}(v(t)) = \frac{\mathrm{d}}{\mathrm{d}t}(0.5t^2 -2.5t +2) \\ a(t) = \frac{\mathrm{d}}{\mathrm{d}t}(0.5t^2) -\frac{\mathrm{d}}{\mathrm{d}t}(2.5t) +\frac{\mathrm{d}}{\mathrm{d}t}(2) \\ a(t) = 0.5\frac{\mathrm{d}}{\mathrm{d}t}(t^2) -2.5\frac{\mathrm{d}}{\mathrm{d}t}(t) +\frac{\mathrm{d}}{\mathrm{d}t}(2) \\ a(t) = 0.5(2t) -2.5 +0 \\ a(t) = t -2.5\)

Part b:

Position is the same thing as displacement (Although they are fundamentally different but it's okay to treat them as similar things in this case). Displacement is just the integral of velocity. If we take the integral of \(v(t)\) that'll be our displacement.

Please refer to my Answer from this question to know the needed information of integrals to solve: brainly.com/question/24687635

Recall:

\(\int (a \cdot f(x)) \mathrm{d}x = a\int f(x) \mathrm{d}x\\\)

\(\int (f(x) +g(x)) \mathrm{d}x = \int f(x) \mathrm{d}x +\int g(x) \mathrm{d}x\\\)

Let \(x(t)\) be our position. Solving for \(x(t)\):

\(v(t) = 0.5t^2 -2.5t +2 \\ \int v(t) \mathrm{d}t = \int (0.5t^2 -2.5t +2) \mathrm{d}t \\ x(t) = \int (0.5t^2) \mathrm{d}t -\int (2.5t) \mathrm{d}t +\int (2) \mathrm{d}t \\ x(t) = 0.5\int (t^2) \mathrm{d}t -2.5\int (t) \mathrm{d}t +\int (2) \mathrm{d}t \\ x(t) = 0.5(\frac{t^3}{3}) -2.5(\frac{t^2}{2}) +2t +C \\ x(t) = \frac{1}{6}t^3 -\frac{5}{4}t^2 +2t +C\)

We still have to solve for \(C\). We are given that at \(t = 0\), \(x(t) = 2.5\). We can therefore write the equation: \(x(0) = 2.5\) or \(\frac{1}{6}(0)^3 -\frac{5}{4}(0)^2 +2(0) +C = 2.5\\\).

Solving for \(C\):

\(\frac{1}{6}(0)^3 -\frac{5}{4}(0)^2 +2(0) +C = 2.5\\ 0 -0 +0 +C = 2.5 \\ C = 2.5\)

We can also write the equation:

\(x(t) = \frac{1}{6}t^3 -\frac{5}{4}t^2 +2t +2.5\\\)

While Piaget, Vygotsky, and Bruner have different perspectives on how learning occurs, they all emphasize the active role of the learner in constructing knowledge and the importance of social interaction and cultural influences in the learning process.

Here's a three-column table evaluating how learning takes place according to Piaget, Vygotsky, and Bruner:

Theorist Approach to Learning Key Concepts

Piaget Constructivism 1. Schema: Individuals actively construct their knowledge through assimilation and accommodation, organizing information into mental structures called schemas. 2. Stages of Development: Learning occurs through cognitive development stages, from sensorimotor to formal operational, where individuals progressively acquire more complex mental abilities. 3. Active Exploration: Children learn best through hands-on exploration and interactions with the physical world.

Vygotsky Sociocultural Theory 1. Zone of Proximal Development (ZPD): Learning takes place within the gap between a learner's actual developmental level and their potential level with guidance from a more knowledgeable other. 2. Social Interaction: Learning is facilitated through social interactions with peers and adults, such as cooperative learning and scaffolding. 3. Cultural Tools: The use of language, symbols, and cultural artifacts plays a central role in cognitive development and learning.

Bruner Constructivism 1. Scaffolding: Instruction should provide support and guidance tailored to the learner's current abilities to help them progress to higher levels of understanding. 2. Discovery Learning: Learners construct knowledge by actively exploring and discovering concepts and relationships on their own. 3. Spiral Curriculum: Learning is organized in a spiral manner, revisiting key concepts and building upon previous knowledge in a progressive and interconnected way.

While Piaget, Vygotsky, and Bruner have different perspectives on how learning occurs, they all emphasize the active role of the learner in constructing knowledge and the importance of social interaction and cultural influences in the learning process.

We have to use the formula of the area of a circle

Where A = 113.04, let's replace this value and solve for r

The radius of the circle is 6 feet long.

We know that the diameter is double the radius. So,

The value of y in simplest form for the point P = (1/2, y) lying on the unit circle is y = ± √(3)/2.

To find the value of y in simplest form for the point P = (1/2, y) lying on the unit circle, we can use the equation of the unit circle, which states that for any point (x, y) on the unit circle, the following equation holds: x^2 + y^2 = 1.

Plugging in the coordinates of the point P = (1/2, y), we get:

(1/2)^2 + y^2 = 1

1/4 + y^2 = 1

y^2 = 1 - 1/4

y^2 = 3/4.

To simplify y^2 = 3/4, we take the square root of both sides:y = ± √(3/4).

Now, we need to simplify √(3/4). Since 3 and 4 share a common factor of 1, we can simplify further: y = ± √(3/4) = ± √(3)/√(4) = ± √(3)/2.

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the line L1 as y = 2x perpendicular to an unknown line L2 passing through the point P = (1, 2), we are to find the equation of line L2. to find the equation of the line L2, we will use the point-slope equation of a line expressed as y-y₀ = m(x-x₀)

m is the slope of the unknown line

(x₀, y₀) is the given point.

First is to get the slope of the known line:

comparing the line L1: y = 2x with the standard equation of the line y = mx+c, it can be seen that m = 2

Then we will calculate the slope of the required line.

Since L1 is perpendicular to L2, the product of their slope will be -1 i.e

mm₁ = -1 where m₁ is the slope of the required line L2.

Given m =2

m₁ = -1/m

m₁ = -1/2

Finally we will calculate the equation of line L2 by substituting the slope of line L2 and the point in the point slope equation above;

y-y₀ = m(x-x₀)

Given (x₀, y₀) = (1,2) and m₁ = -1/2

y-2 = -1/2(x-1)

open the parenthesis

y-2 = -x/2+1/2

multiply through by 2:

2y-4 = -x+1

2y+x = 1+4

2y+x = 5

Hence the equation of the line L2 is 2y+x = 5

The true statements are;

1) AB + BC = AC

Length of BC = |6 - 1|

2) ∠JMK = 50°

∠KML = 35°

1) From the given number line interval, we can deduce the interpretation as follows;

AB + BC = AC

Length of BC = 5 units or |6 - 1|

Length of B = 3 Units

2) We can see that ∠JML is an angle triangle. Thus, ∠JML = 85°. Thus;

6x + 2 + 4x + 3 = 85

10x + 5 = 85

10x = 85 - 5

10x = 80

x = 80/10

x = 8°

Thus;

∠JMK = 6(8) + 2

∠JMK = 50°

∠KML = 85° - 50°

∠KML = 35°

The lowest score for the normally distribution with mean 72 and standard deviation 8 is equal to 82.

Mean of the normally distributed data 'μ' = 72

Standard deviation 'σ ' = 8

Lowest score with 10% ( 90percentile )

z = InvNorm(0.90)

 = 1.28

Let 'X' be the lowest score for the normal distribution

z = ( X - μ ) / σ

Substitute the values we get,

⇒ 1.28 = ( X - 72 ) / 8

⇒ X - 72 = 1.28 × 8

⇒ X = 10.24 + 72

⇒ X = 82.24

⇒ X = 82 ( round to an integer )

Therefore, the lowest score for normally distribution which will place manage on 90th percentile with given mean and standard deviation is equal to 82.
