Step-by-step explanation:

Use the arithmetic progression formula:  S =n/2(2a + (n-1)d)

a = 5, d = 5, n = 5

S = 5/2((2(5) + (5-1)(5)) = 75

The graph of y = 2 sin(x) + 2 is given by the following option:

Graph A.

The standard definition of the sine function is given as follows:

y = Asin(B(x - C)) + D.

For which the parameters are given as follows:

The function in this problem has an amplitude of 2, meaning that before the vertical shift, it oscillates between -2 and 2.

Due to the vertical shift, the function is going to oscillate between 0 and 4, with a period of 2π and no phase shift, crossing the midline of y = 2 at the origin, hence Graph A is the correct graph.

Answer:

Let's call the number of 7,000 gallon tank cars "x1", the number of 14,000 gallon tank cars "x2", and the number of 28,000 gallon tank cars "x3".

We can write the following constraints based on the total carrying capacity of the fleet:

7,000x1 + 14,000x2 + 28,000x3 = 532,000

x1 + x2 + x3 = 25

x1, x2, x3 >= 0 (since we can't have a negative number of tank cars)

This is a linear programming problem, which can be solved using simplex method or the graphical method.

By using the graphical method, we find that there are multiple optimal solutions. For example, one solution is x1 = 11, x2 = 7, and x3 = 7. This means that the manufacturer should lease 11 7,000 gallon tank cars, 7 14,000 gallon tank cars, and 7 28,000 gallon tank cars to meet the total carrying capacity requirement of 532,000 gallons.

So, the answer to the question is: There are multiple possible combinations of how the tank cars should be leased. The combinations are obtained from the equations x1 = 11 + 7t, x2 = 7 + 7t, and x3 = 7 + 7t.

The meaning of the function notations are

G(Jada) = 4 means that the first name Jada has four letters

C(11-15)= chemistry means that the Monday class for 11-15 is chemistry

How to interpret the function notations?

The meaning of the function G

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

Function G gives the number of letters in the first name for its output.

Next, we have

G(Jada) = 4

Using the meaning of the function, we have

G(Jada) = 4 means that the first name Jada has four letters

The meaning of the function C

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

Function C gives a student's Monday class for its output.

Next, we have

C(11-15)= chemistry

Using the meaning of the function, we have

C(11-15)= chemistry means that the Monday class for 11-15 is chemistry

The evaluation of the function expressions gives:

(q + f)(5) = 1

(f - q)(2) = -2

(q f)(4) = 9

(f /q)(0) = 1

A function is an expression that shows the relationship between the independent variable and the dependent variable.  A function is usually denoted by letters such as f, g, etc.

From the graph, when c = 5, q(5) = 0, f(5) = 1. Thus:

(q + f)(5) = 0 + 1 = 1

From the graph, when c = 2, f(2) = 0, q(2) = 2. Thus:

(f - q)(2) = 0 - 2 = -2

From the graph, when c = 4, q(4) = 3, f(4) = 3. Thus:

(q f)(4) = 3 * 3 = 9

From the graph, when c = 0, f(0) = 4, q(0) = 4. Thus:

(f /q)(0) = 4/4 = 1

By making the discriminant equal to zero, we can see that the quadratic equation has one real solution only for z = 10.

For a general quadratic equation:

a*x^2 + b*x + c = 0

We define the discriminant as:

D = b^2 - 4ac

The quadratic equation will have only one real solution only if the discriminant is equal to zero.

Here the quadratic is:

(z - 5)*x^2 - z*x + 5 = 0

Then the discriminant is:

(-z)^2 - 4*5*(z - 5)

And that must be equal to zero, then we need to solve:

z^2 - 20*(z - 5) = 0

z^2 - 20z + 100 = 0

Using the quadratic formula we will get:

[tex]z = \frac{20 \pm \sqrt{(-20)^2 - 4*1*100} }{2} \\\\z = \frac{20 \pm 0}{2} \\\\z = 10[/tex]

Answer: The outlier is $95 and the plot is D.

Step-by-step explanation:

          An outlier is the data value that's much larger or much smaller than the other data values. Here, that is $95.

          Excluding this value, our smallest is $15 and the largest is $60. We plot a dot at both of these points.

          The middle dot is the median. To find this, we will arrange the values in order and find the middle value. (We are excluding $95.) After doing this process, we see the middle dot is at 39.

    $15, $20, $38, $60, $45, $40, $35, $50

    $15, $20, $35, $38, $40, $45, $50, $60

Answer:

Step-by-step explanation:

Let's call the number of friends "f". Since each friend paid $12.75 for their meal, the cost of the meals can be represented as f * 12.75. And since each friend left the same amount for a tip, the cost of the tips can be represented as t * f.

The total cost of the dinner including the tip was $61, so we can write the following equation:

f * 12.75 + t * f = 61

Expanding the left side of the equation:

12.75f + t * f = 61

Combining like terms:

13.75f + t = 61

Solving for t:

t = 61 - 13.75f

So, the equation that describes the situation is t = 61 - 13.75f.

What exactly is a sequence?

A sequence is a collection of numbers that follows pattern. Olivia, for example, has been offered a position with a beginning monthly pay of $1000 and a yearly raise of $500. To figure out her monthly pay for the first three years? The prices will be $1000, $1500, and $2000. Note that Olivia's income over a number of years creates a sequence as they follow a pattern where the numbers increase by $500 each time.

What is an absolute value inequality?

The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.

An expression using absolute functions and inequality signs is known as an absolute value inequality. One example of an absolute value inequality with a larger than symbol is the statement |x + 3| > 1.

Answer:

After rounding the nearest tenth of a square foot, the surface area of the  circular cylinder is 131.88 feet^2.

Step-by-step explanation:

To find surface area of a right circular cylinder we can use the formula,

A = 2πrh + 2πr^2

Here A is surface area,

π is mathematical constant ,

r is radius, and h is the height of the cylinder.

We have

r = 3 ft

h = 4 ft,

Now we put the values to find the surface area,

A = 2π × 3 × 4 + 2π ×3^2

A = 24π + 18π

A = 42π

A= 42×3.14                             (we know π = 3.14 )

A = 131.88

After rounding the nearest tenth of a square foot, the surface area of the  circular cylinder is 131.88 feet^2.

The system of equation is written as follows

y = 90 + x

y = 40 + 6x

With regards to cost the choices will be equivalent in 10 day

Assuming additional day is x

Felipe's Moving, they would pay $90 for the first day plus $1 per additional day:

Answer:

  y = 1/8x +1/64

Step-by-step explanation:

You want the equation of the line that is tangent to the curve y = x³ -x⁴ in exactly two places.

Since the tangent line is not crossed, the difference between the line and the given curve is a 4th-degree polynomial with two roots, each of multiplicity 2. If those are 'a' and 'b', we can write for line y = mx +p, ...

  mx +p -(x³ -x⁴) = (x -a)²(x -b)² = 0

  x⁴ -x³ +0x² +mx +p = x⁴ -2(a+b)x³ +(a²+4ab+b²)x² -2ab(a+b)x +a²b²

Equating coefficients, we have ...

The coefficient of x³ tells us ...

  a +b = 1/2

The coefficient of x² tells us ...

  0 = (a +b)² +2ab

  0 = (1/2)² +2ab

  ab = -1/8

Using these value, we can find the equation of the line to be ...

  m = -2ab(a+b) = -2(-1/8)(1/2) = 1/8

  p = (ab)² = (-1/8)² = 1/64

The equation of the line is ...

  y = 1/8x +1/64

To find the line, we did not need the coordinates of the points of tangency. They are ((1-√3)/4, (3-2√3)/64) and ((1+√3)/4, (3+2√3)/64).
