Answer:

  $6.90

Step-by-step explanation:

Apparently the cost function for the Oyster is ...

  c(n) = 90,000 +5.40n

Then the cost for 60,000 units is ...

  c(60,000) = 90,000 +5.40·60,000 = 414,000

In order to break even, Sackville Plastics must sell these for ...

  $414,000/(60,000 units) = $6.90/unit

Answer: Yes, the correlation coefficient is statistically significant

The correlation coefficient describes how one variable actions when it comes to every other. A high-quality correlation shows that the 2 circulate within the identical path, with a +1.zero correlation once they move in tandem. A poor correlation coefficient tells you that they as a substitute flow in opposite directions. A correlation of 0 shows no correlation in any respect.

where ρ corresponds to the population correlation.

The sample size is n = 17,

so then the number of degrees of freedom is df = n-2 = 17-2 = 15

The corresponding critical correlation value re for a significance level of a 0.05, for a two-tailed test is た= 0.482

Observe that in this case,

              the null hypothesis H0 : ρ-0 is rejected

                             if |r> re 0.482.

Based on the sample correlation provided, we have that lrl = 0.595 >=0.482,                            

which is concluded that the null hypothesis is rejected.

The Fundamental Theorem of Calculus states that if a function f is continuous on the closed interval [a,b] and F is the antiderivative of f on [a,b], then the definite integral of f from a to b is equal to F(b) - F(a).

For the first question, we can use the Fundamental Theorem of Calculus and the Chain Rule to find the derivative:

ddx∫x−1(3t5−t)30dt = (3x5-x)/30

For the second question, we can use Part 2 of the Fundamental Theorem of Calculus:

d/da ∫a^3 (7t^2 + 6) dt = 7a^6 + 6a^3

Then, we can use the Chain Rule to find the derivative of the function with respect to t:

d/dt (7a^6 + 6a^3) = 42a^5(da/dt) + 18a^2(da/dt)

Since the problem gives us da/dt = 20, we can substitute to find:

d/dt (7a^6 + 6a^3) = 8400a^5 + 3600a^2

Step-by-step explanation:

asymptotes:=-1 and hole:x=4

The height at time t (in seconds) of a mass, oscillating at the end of a spring, is s(t) = 300 + 16 sin t cm. We have to find the velocity and acceleration at t = π/3 s.

Let's first find the velocity of the mass. The velocity of the mass is given by the derivative of the position of the mass with respect to time.t = π/3 s
s(t) = 300 + 16 sin t cm
Differentiating both sides of the above equation with respect to time
v(t) = s'(t) = 16 cos t cm/s

Now, let's substitute t = π/3 in the above equation,
v(π/3) = 16 cos (π/3) cm/s
v(π/3) = -8√3 cm/s

Now, let's find the acceleration of the mass. The acceleration of the mass is given by the derivative of the velocity of the mass with respect to time.t = π/3 s
v(t) = 16 cos t cm/s
Differentiating both sides of the above equation with respect to time
a(t) = v'(t) = -16 sin t cm/s²
Now, let's substitute t = π/3 in the above equation,
a(π/3) = -16 sin (π/3) cm/s²
a(π/3) = -8 cm/s²
Given, s(t) = 300 + 16 sin t cm, the height of the mass oscillating at the end of a spring. We need to find the velocity and acceleration of the mass at t = π/3 s.
Using the above concept, we can find the velocity and acceleration of the mass. Therefore, the velocity of the mass at t = π/3 s is v(π/3) = -8√3 cm/s, and the acceleration of the mass at t = π/3 s is a(π/3) = -8 cm/s².
At time t = π/3 s, the velocity of the mass is -8√3 cm/s, and the acceleration of the mass is -8 cm/s².

Answer:

An equation of the line with the given information with

m = 4 and point A(-1, -5) is:

Step-by-step explanation:

As the equation of a line in point-slope form is given by:

\(y-y_1=m\left(y-x_1\right)\)

where m is the slope.

Given:

Substituting the values in the equation of a line in point-slope form

\(y-y_1=m\left(x-x_1\right)\)

\(y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)\)

\(y+5=4\left(x+1\right)\)

subtract 5 from both the sides

\(y+5-5=4\left(x+1\right)-5\)

\(y=4x-1\)

Answer:

Step-by-step explanation:

A,B and C would be the inside of the plane not outside.

The equation of the linear function represented by the given table in slope intercept form is y = 2x - 2.

The equation of line can be determine using the slope-intercept formula;

y = mx + b

Where m is slope and b is the y-intercept.

From the given table, we use to points;

Point 1( -1, -4 )

Point 2( 1, 0 )

First, we find the slope of the line.

Slope m = (y₂ - y₁) / (x₂ - x₁ )

Slope m = ( 0 - (-4) ) / (1 - (-1) )

Slope m = ( 0 + 4) ) / (1 + 1) )

Slope m = 4 / 2

Slope m = 2

Next, we find the y-intercept b, using a slope m = 2 and a point ( -1, -4 ).

y = mx + b

-4 = 2(-1) + b

-4 = -2 + b

b = -4 + 2

y-intercept b = -2

Now that we have the slope m and y-intercept b, plug the values into to y = mx + b to determine the equation of line.

y = mx + b

y = 2x + (-2)

y = 2x - 2

Therefore, the equation of the linear function is y = 2x - 2.

Answer:

(-1,3)

Step-by-step explanation:

we need to replace the values x and y for every point and see if the point satisfies all the inequations.

Point (-2,3):

x - y ≥ -4

-2 - 3 ≥ -4

-5 ≥ -4

Then, -5 is not greater than -4, so that point is not a solution.

Point (-1,3):

x - y ≥ 4                      2x - y ≤ 5                2y + x > 1

-1 - 3 ≥ 4                     2(-1) - 3 ≤ 5             2(3) + (-1) > 1

-4 ≥ -4                        -5 ≤ 5                            5 > 1

Then, (-1,3) is a solution

Point (0,0):

x - y ≥ 4                      2x - y ≤ 5                2y + x > 1

0 - 0 ≥ 4                      2(0) - 0 ≤ 5             2(0) + (0) > 1

0 ≥ -4                           0 ≤ 5                            0 > 1

Then, 0 is not greater than 1, so that point is not a solution.

Point (2,-2):

x - y ≥ 4                      2x - y ≤ 5              

2 - (-2) ≥ 4                  2(2) - (-2) ≤ 5          

4 ≥ -4                           6 ≤ 5                    

Then, 5 is not greater than 6, so that point is not a solution.

5.5n - 52=25

Adding 52:

5.5n =25+52=77

The system of inequalities that indicates what is necessary to obtain the stores' goal is:

x+y≤25

475x+360y≥7600

According to the information provided, you know that the owner never has more than 25 items total in the store which means that the sum of the number of televisions and projection systems is less than or equal to 25, the inequality is:

x+y≤25, where:

x is the number of televisions

y is the number of projection systems

According to the question, this indicates that the price per television is $475 and the price per projection system is $360 and that the store looks to sell at least $7600 worth of televisions and projection systems per day which means that the result of adding up the sales of televisions and projection systems should be greater than or equal to 7600:

Answer:

(c) is correct.

Step-by-step explanation:

When two lines cross each other, the angles opposite to each other are called vertically opposite angles. They are always equal.

In this given figure,

Line TW and RU cross each other at Q, it means

\(\angle RQW=\angle TQU\) (vertically opposite angles)

Hence, the correct option is (c).

The presence of dappled brown patches on a patient's cheek may indicate a condition called melasma. Melasma is a common skin condition that typically affects women and is associated with hormonal changes, sun exposure, and genetic factors.

Dappled brown patches on the cheek often suggest a condition called melasma. Melasma is a common skin disorder characterized by the development of dark, irregularly shaped patches on the skin. It typically affects women, especially those with darker skin tones, and is often associated with hormonal changes, such as during pregnancy or with the use of birth control pills. Sun exposure is another contributing factor to the development of melasma. Genetic factors also play a role, as it tends to run in families. Melasma is not a harmful or dangerous condition but can cause cosmetic concerns and affect a person's self-esteem.

To manage melasma, various treatment options are available. These include topical creams containing ingredients such as hydroquinone, tretinoin, or corticosteroids, which can help lighten the patches over time.

Chemical peels that involve the application of a chemical solution to exfoliate the skin and reduce hyperpigmentation may also be used. In some cases, laser therapy can be beneficial to target and break up the excess pigment in the affected areas.

It's important to note that melasma may recur, especially with sun exposure, so it's essential to protect the skin from the sun by wearing sunscreen and using protective clothing. Consulting a dermatologist is recommended to determine the most appropriate treatment approach for an individual case of melasma.
