which equal to cos 74

Answer:

Step-by-step explanation:

E is the midpoint of Ac & D is the midpoint of AB

DE = (1/2)BC        {Midpoint theorem}

\(x +1 = \dfrac{1}{2}(4x - 6)\\\\\\ Multiply \ the \ whole \ equation \ by 2\\\\ 2*(x+1) =2*\dfrac{1}{2}*(4x - 6)\)

2*x + 2*1 = 4x - 6

2x + 2 = 4x - 6

Add 6 to both sides

2x + 2 + 6 = 4x

2x + 8 = 4x

Subtract 2x from both sides

8 = 4x - 2x

2x = 8

Divide both sides by 2

x = 8/2

x = 4

Step-by-step explanation:

when graphed, x=1 goes up and down which makes it's slope undefined

Answer:

(infinity)

Step-by-step explanation:

rate of change for the equation x = 1

use the formula: y = mx + b

where:

y = how far up the line goes

m = slope

x = how far along

b = Y-intercept

the equation is a vertical line,

so the slope = ∞ (infinity)

1. The velocity at time t , v(t) = (18t² + 3 ) m/s

2. The velocity at time t = 3 seconds = 165 m/s

3. The acceleration at time t, a(t) =( 36t )m/s²

4. The acceleration at time t = 3 seconds = 108 m/s²

The quantity that tells us how fast an object is moving anywhere along its path is the instantaneous velocity.

Instantaneous acceleration is defined as the ratio of change in velocity during a given time interval such that the time interval goes to zero.

1. s(t) = 6t³ + 3t +9

to find the velocity at time t, we differentiate s(t)

= 18t² + 3

2. at t = 3s

= 18(3)² +3

= 165 m/s²

3. v(t) = 18t² + 3

to get the acceleration at time t, we differentiate v(t)

= 36t

4. when t = 3

a = 36 × 3

= 108 m/s²

Given:

Sample size, n = 52

correlation coefficient, r = -0.25

Let's find the coefficient of determination of the person's correlation.

To find the coefficient of determination, we have:

coefficient of determination = r²

Thus, we have:

coefficient of determination = r² = -0.25² = 0.0625

Therefore, the coefficient of determination is 0.0625

To find the degrees of freedom, apply the formula:

df = n - 2

Where

df is the degrees of freedom

n is the sample size = 52

Hence, we have:

df = 52 - 2 = 50

The degrees of freedom is = 50

ANSWER:

• Coefficient of determination = 0.0625

• Degrees of freedom = 50

The profit function is P(x) = -500.523x^2 + 600x - 200.

To find the profit function, P(x), we need to subtract the cost function, C(a), from the revenue function, R(x).

Given:

Cost function: C(a) = 500x^2 + 300

Revenue function: R(x) = -0.523x^2 + 600x - 200 + 300

Profit function, P(x), is obtained by subtracting the cost function from the revenue function:

P(x) = R(x) - C(a)

P(x) = (-0.523x^2 + 600x - 200 + 300) - (500x^2 + 300)

Simplifying the expression:

P(x) = -0.523x^2 + 600x - 200 + 300 - 500x^2 - 300

P(x) = -500x^2 - 0.523x^2 + 600x + 300 - 200 - 300

P(x) = -500x^2 - 0.523x^2 + 600x - 200

Combining like terms:

P(x) = (-500 - 0.523)x^2 + 600x - 200

Simplifying further:

P(x) = -500.523x^2 + 600x - 200

In Geometric progression the common ratio is the ratio of any two consecutive terms where nth term is denominator & n-1 th term is numerator.Given by,

\(r = \frac{a_{n - 1} }{a_n} \)

in the given series

\(r = \frac{a_{1} }{a_2} = \frac{1024}{128} = 8\)

\(r = \frac{a_{2} }{a_3} = \frac{128}{16} = 8\)

\(r = \frac{a_{3} }{a_4} =\frac{16}{2} = 8\)

To calculate Fred's power, we can use the formula:

Power = Work / Time

Given that Fred did 600 J of work in 60 seconds, we can substitute the values into the formula:

Power = 600 J / 60 s

Power = 10 W

Therefore, the correct answer is:

D. 10 W

Step-by-step explanation:

Answer:

Power = Work/Time

Power = 600 J/60 s = 10 W

To find the total cost of office supplies, applying the order of operations (PEMDAS) is crucial. A stapler priced at $8 and 5 pens, each costing $2, are required. By following the correct order, we calculate the cost of the stapler separately, then the pens. Adding the stapler cost ($8) to the pen cost ($10) yields a total of $18. Adhering to the order of operations ensures accurate calculations and determines the correct total cost of the supplies.

To solve the problem, let's demonstrate the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

The correct method to solve the problem is as follows:

1. Calculate the cost of the stapler: $8.

2. Calculate the cost of the pens: 5 pens * $2/pen = $10.

3. Add the cost of the stapler and the pens to find the total cost: $8 + $10 = $18.

Therefore, the total cost of the supplies for the office is $18.

Now, let's demonstrate the incorrect method by not following the order of operations:

1. Add the cost of the stapler and the pens first: $8 + (5 * $2).

2. Perform the multiplication: $8 + (5 * $2) = $8 + $10 = $18.

In this case, the incorrect method led to the same result as the correct method. However, this may not always be the case. If the order of operations is not followed correctly, it can lead to incorrect results.

It is essential to follow the order of operations to ensure accurate calculations. Parentheses should be evaluated first, followed by exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).

By correctly following the order of operations, we can obtain the accurate total cost of the supplies for the office, which is $18.

The equation of the Parabola in vertex form that has a vertex of (4, -2) and a y-intercept of (0, -66) is:y = -4(x - 4)^2 - 2

The vertex form of a parabola is given by:y = a(x - h)^2 + k

where (h, k) is the vertex of the parabola.

We are given that the vertex is (4, -2), so we can substitute these values in the equation to get:y = a(x - 4)^2 - 2

Now, we need to find the value of "a". To do this, we can use the fact that the y-intercept is (0, -66). Since the point (0, -66) lies on the parabola, we can substitute x = 0 and y = -66 in the equation above to get:-66 = a(0 - 4)^2 - 2

Simplifying this, we get:-66 = 16a - 2

Adding 2 to both sides, we get:-64 = 16a

Dividing both sides by 16, we get:a = -4

Substituting this value of "a" in the equation above, we get the equation of the parabola in vertex form:y = -4(x - 4)^2 - 2

Therefore, the equation of the parabola in vertex form that has a vertex of (4, -2) and a y-intercept of (0, -66) is:y = -4(x - 4)^2 - 2
