Answer:

g(-2) = 0

g(4) = -4

Step-by-step explanation:

The outputs of each inequality are the numbers directly next to the parentheses. If an "x" value lies within a particular inequality, the values of the function are the corresponding output.

Remember, the "greater than or equal to" sign (≤) indicates that the "x" value can be equal to the number on the left. The "greater than" symbol (<) indicates that the number to the right cannot satisfy the inequality.

x = -2 lies within the inequality -2 ≤ x < 4. All "x" values that fall within this range are g(x) = 0. Therefore, g(-2) = 0.

x = 4 lies within the inequality 4 ≤ x < 10. All "x" values that fall within this range are g(x) = -4. Therefore, g(4) = -4.

h(x) = -7/6x - 25/6.

Given h(-1)=-2 and h(-7)=-9

For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.

To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

h(-1) = -2 is a point on the line, so we can write it as (-1, -2).

h(-7) = -9 is another point on the line, so we can write it as (-7, -9).

Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6

Now we can find b using one of the points and m. Let's use (-1, -2):

y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b

b = -25/6

Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6

We can check our answer by plugging in the two given points:

h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9

The answer is h(x) = -7/6x - 25/6.

The profit on the shares is $2180

From the question, we have the following parameters that can be used in our computation:

Number of shares = 50

Cost price = $98.40

Current price = $142.00

The profit on the shares is then calculated as

Profit = (Current price - Cost price) * Number of shares

Substitute the known values in the above equation, so, we have the following representation

Profit = (142 - 98.40) * 50

Evaluate

In the context of engineering and construction, a bearing point refers to a specific location or area. The bearing of A from C is 230°.

The load from the structural element is transferred to the foundation at a bearing point, which is often a concentrated load point.

To avoid structural failure, settling, or excessive deflection of the part, it is crucial to make sure the bearing point is properly designed and supported.

Since the bearing of C from A is 050°, we can find the bearing of A from C by adding 180° to 50°, which gives us:

Bearing of A from C = 50° + 180° = 230°

Therefore, In the context of engineering and construction, a bearing point refers to a specific location or area. The bearing of A from C is 230°.

Complete question -

A pony walks approximately 78.4 feet to complete one trip around the circular pony ride.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle or the distance around the circle is expressed mathematically as;

C = 2πr or C = πd

Where r is radius, d is diameter and π is constant pi ( π = 3.14 ).

The distance traveled by a pony to complete one trip around the circle is equal to the circumference of the circle.

Given that the diameter of the circle is 25 feet, we can calculate the circumference using the above formula as follows:

C = πd

C = 3.14 × 25 feet

C = 78.5 feet.

Therefore, the measure of the circumference is approximately 78.5 feet.

To find the critical points at which profit is maximized given the total revenue TR = 4700 - 302 and total cost TC = 320/10,500, we need to compute the marginal revenue and marginal cost, equate MR = MC to find the optimal quantity Q∗, verify if Q∗ is a relative maximum point, and compute the maximum profit level (π) by evaluating π∗ = 9(π(Q∗)).

Marginal Revenue (MR) is the derivative of the total revenue function with respect to quantity (Q). In this case, MR = dTR/dQ. By taking the derivative of TR = 4700 - 302 with respect to Q, we can find the expression for MR.

Marginal Cost (MC) is the derivative of the total cost function with respect to quantity (Q). In this case, MC = dTC/dQ. By taking the derivative of TC = 320/10,500 with respect to Q, we can find the expression for MC.

To find the optimal quantity Q∗, we equate MR and MC by setting MR = MC and solve for Q. This is because profit is maximized when MR equals MC.

Once we have found Q∗, we need to verify if it is a relative maximum point. This can be done by checking the second derivative of the profit function and determining if it is negative at Q∗. If the second derivative is negative, it confirms that Q∗ is a relative maximum point.

Finally, to compute the maximum profit level (π∗), we evaluate π(Q∗) by substituting Q∗ into the profit function. In this case, we can multiply the value of π(Q∗) by 9 to obtain the maximum profit level (π∗).

Step-by-step explanation:

Blake started with 94 flyers before 14 of them blew away.To solve this story problem, we can follow these steps:

1. Start by identifying the key information provided in the problem:
  - 14 flyers had blown away by the time Blake arrived.
  - Blake put 50 flyers on blue cars, 26 flyers on white cars, and 32 flyers on silver cars.

Using the decay formula, the particular antibiotic with half-life of 16 hours, will decrease to 30-milligrams in the blood after 27.79 hours.

We can use the decay formula to solve the problem:

A(t) = A(0) . (0.5)^(t/T)

Where:

A(t) is the remaining quantity at time t

A(o) is the initial quantity

t  is the time interval

T is the half-life rate

In the given problem:

A(0) = 100 milligram

T = 16 hours

A(t) = 30 milligram

We need to find t such that the remaining quantity of this antibiotic is 30 mg.

Substitute the given parameters into the formula:

A(t) = A(0) . (0.5)^(t/T)

30 = 100 . (0.5) ^(t/16)

Taking the logarithm:

log (30) = log [100 . (0.5) ^(t/16)]

Use the logarithm property, log(A.B) = log A + log B

log (30) = log (100) + log [(0.5) ^(t/16)]

Use the logarithm property, log(Aⁿ) = n.log A

log (30) = log (100) + (t/16) . log (0.5)

log (30) = 2 + (t/16) . log (0.5)

(t/16) . log (0.5)  = log (30) - 2

t/16 = 1.737

t = 1.737 . (16) = 27.79 hours

Step-by-step explanation:

The quadratic equation x² - 3x - 28 = 0 has two real rational solutions. Therefore the correct option is 3. Two real rational solutions

To determine the type of solutions to the quadratic equation x² - 3x - 28 = 0, we can use the discriminant, which is the term b² - 4ac in the quadratic formula.

In this case, the coefficients are:

a = 1 (coefficient of x²)

b = -3 (coefficient of x)

c = -28 (constant term)

The discriminant is calculated as follows:

Discriminant = b² - 4ac

Discriminant = (-3)² - 4(1)(-28)

Discriminant = 9 + 112

Discriminant = 121

Now, let's analyze the value of the discriminant:

1. If the discriminant is positive (greater than zero), there are two real solutions.

2. If the discriminant is zero, there is one repeated real solution.

3. If the discriminant is negative (less than zero), there are two complex solutions.

In this case, the discriminant is 121, which is positive. Therefore, the quadratic equation x² - 3x - 28 = 0 has two real rational solutions.

Answer:

Maximum height of the ball = 100 m

Time to reach the maximum height = 2.5 seconds

Step-by-step explanation:

Function that models the height h(t) of the ball and time 't',

h(t) = -16t² + 80t

Convert this equation into vertex form,

h(t) = -16(t²- 5t)

     = -16[t² - 2(2.5t) + (2.5)² - (2.5)²]

     = -16[[t² - 2(2.5t) + (2.5)²] + 16(2.5)²

     = -16(t - 2.5)² + 16(6.25)

     = -16(t - 2.5)² + 100

By comparing this equation with,

g(t) = a(x - h)² + k

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

Vertex of the given parabola will be → (2.5, 100)

Therefore, maximum height of the ball = 100 m

Time taken by the ball to reach the maximum height = 2.5 seconds

Given:

The side lengths of two cubes are 2.5 yd and 2 yd.

To find:

The side length of third cube.

Solution:

From the given figure it is clear that the cubes are inclined to each other in such a way so that they form a right angle triangle and side length of third cube is the base.

Let x be the side length of the third cube.

Using Pythagoras theorem, we get

\(Hypotenuse^2=Base^2+Perpendicular^2\)

\((2.5)^2=(x)^2+(2)^2\)

\(6.25=x^2+4\)

\(6.25-4=x^2\)

\(2.25=x^2\)

Taking square root on both sides, we get

\(x=\pm\sqrt{2.25}\)

\(x=\pm 1.5\)

Side cannot be negative. So,

\(x=1.5\)

Therefore, the side length of the  third cube is \(x=1.5\) yd.
