Evaluate the expression when c equals 3 and y = -7. -2c+y

Answer:

Step-by-step explanation:

The decay rate of 80% per year means that after each year, the value of the quantity decreases by 80/100 * 3600 = 2880.

To find the value of the quantity after 0.2 decades, we need to multiply the number of years by 10, since a decade is equal to 10 years. In this case, 0.2 decades is equal to 0.2 * 10 = 2 years.

The value of the quantity after 2 years can be found using the formula:

3600 * (1 - 0.8)^2

Plugging in the values, we get:

3600 * (1 - 0.8)^2 = 3600 * (0.2)^2 = 3600 * 0.04 = 144

So, the value of the quantity after 0.2 decades, to the nearest hundredth, is 144.

The equation which is in the quadratic form is 6x⁴ + 7x² - 3 = 0. So Option B is correct.

An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.

Among the given equations, we can see that the first, third, and fourth equations are not quadratic in form, since they contain x raised to powers other than 2.

The second equation, 6x⁴ + 7x² - 3 = 0, can be written in quadratic form by making a substitution.

If we let y = x², then we can write the equation as 6y² + 7y - 3 = 0,

which is a quadratic equation in y. Substituting back x² for y,

we get:

6x⁴ + 7x² - 3 = 0

So the second equation is quadratic in form.

The value of x from the given triangle is 17.5 units.

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

We know that, sinθ= Opposite/Hypotenuse

Here, sin31°=9/x

0.515=9/x

x=9/0.515

x=17.5

Therefore, the value of x is 17.5 units.

In economics, business, and notably cost accounting, the break-even point (BEP) is the point at which total costs and total revenues are equal, or "even" and we need to sell a total of 1967 tires at the price of $89 to break even.

The break-even point (BEP) is the point at which total costs and total revenues are equal, or "even," in economics, business, and particularly cost accounting.

Although opportunity costs have been paid and capital has received the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."

In other words, all necessary expenses are covered, and neither a profit nor a loss is realized.

So, for the break-even:

= 175000/89

= 1,966.29

2^3  /  2^7 =   2^(3-7)   =   2^(-4)   =   1/ (2^4)   =   1/16   =   .0625  

   ~~~~pick your poison

The required expression [tex]2^3/2^7[/tex], after simplification is equivalent to 1/16.

To simplify the expression [tex]2^3/2^7[/tex], we can apply the rule of exponentiation that states when dividing two numbers with the same base, we subtract the exponents.

In this case, the base is 2.

Using the rule, we subtract the exponent of the denominator from the exponent of the numerator:

[tex]2^3/2^7 = 2^{7} = 2^{-4}[/tex]

The expression [tex]2^{-4}[/tex] can be further simplified by using the rule that states any number raised to a negative exponent is equal to the reciprocal of the number raised to the positive exponent:

[tex]2^{-4} = 1/2^4[/tex]
      = 1/16

Therefore, the expression [tex]2^3/2^7[/tex] is equivalent to 1/16.

CJ's plan to construct a square inscribed in a circle is through 7 steps.

step 1:

First, draw a circle using a compass (any size).

Step 2:

Using a ruler, draw a diameter or straight line along the length of the circle and pass through its center.

Step 3:

Then open the compass through the circle. Then bring the compass tip to one end of the diameter and swing the compass over the circle to draw an arc.

Step 4:

Keeping the compass the same length, move it to the other side of the diameter, swing it over the circle again, and create another arc until the two arcs intersect. Step 5:

Repeat steps 3 and 4, this time using the same compass size to create an arc under the circle.

Step 6:

Connect the top and bottom intersections of the circle with a ruler or ruler. This creates a perpendicular bisector that bisects the diameter and forms a 90 degree angle.

Tony can afford the car insurance, and he has enough money( $426.33 ) left over each month to cover other expenses.

We need to calculate the cost of the insurance and compare it to his monthly pay.

According to the information given,

Tony's yearly pay is $8,320

and his monthly pay is $693.

If we round his yearly pay to $8,000, his monthly car insurance will be 1/30 of that amount, or $266.67.

Since Tony's monthly pay is $693, and his monthly car insurance will cost $266.67, he can afford the insurance. He will have $426.33 remaining each month after paying for the insurance.

Therefore, Tony can afford the car insurance, and he has enough money left over each month to cover other expenses. However, this calculation assumes that Tony has no other major expenses or debts, and it is always a good idea to budget carefully and consider all potential costs before making a significant purchase.

Answer:

Step-by-step explanation:

The long-run behavior of a function can be determined by examining its asymptotes and the behavior of the function near these asymptotes.

For the function f(p)=(p+1)^3(p+4)^3(p-1), there are three points to consider as possible asymptotes: p = -1, p = -4, and p = 1.

At p = -1, the factor (p-1) is equal to zero, so the function has a vertical asymptote there. This means that as p approaches -1 from either side, the function will approach infinity.

At p = -4, the factor (p+4)^3 is equal to zero, so the function also has a vertical asymptote there. Similarly, as p approaches -4 from either side, the function will approach infinity.

At p = 1, the factor (p+1)^3 is equal to zero, so the function has another vertical asymptote there. In this case, as p approaches 1 from either side, the function will approach negative infinity.

So, the long-run behavior of the function can be described as follows:

The function approaches infinity as p approaches -1 or -4 from either side.

The function approaches negative infinity as p approaches 1 from either side.

Therefore, the long-run behavior of f(p)=(p+1)^3(p+4)^3(p-1) is characterized by three vertical asymptotes at p = -1, p = -4, and p = 1.

Explanation:

Each factor is a cubic of degree 3.

The degree of the entire polynomial is 3+3+3 = 9.

Since the degree is odd and the leading coefficient is positive, this means the graph falls to the left and rises to the right.

"falls to the left" means [tex]\text{As } p \to -\infty, f(p) \to -\infty[/tex]

"rises to the right" means [tex]\text{As } p \to \infty, f(p) \to \infty[/tex]

The most appropriate viewing range for the quadratic function is given as follows:

The quadratic function for this problem is defined as follows:

f(x) = x² - 11x + 18.

The function can be factored as follows:

f(x) = (x - 2)(x - 9).

Hence the roots are:

Meaning that the viewing range should include x = 2 and x = 9.

The coefficients of the function are:

a = 1, b = -11, c = 18.

Hence the x-coordinate of the vertex is of:

x = -b/2a

x = 11/2

x = 5.5.

Hence the minimum value of the function is the y-coordinate of the vertex, given as follows:

y = 5.5² - 11(5.5) + 18

y = -12.25.

Meaning that Ymin should be less than -12.25.
