Step-by-step explanation:

To solve for x, we'll first need to simplify the equation by combining like terms:

0.6x - 5 = 0.1x + 7

0.6x - 0.1x = 7 + 5

0.5x = 12

x = 12 / 0.5

x = 24

Therefore, the value of x that makes the equation true is 24.

Step-by-step explanation:

the angle at Y = 1/2 × (arc angle WZ - arc angle ZX).

so,

42 = (arc angle WZ - 51)/2

84 = arc angle WZ - 51

135° = arc angle WZ

the arc angle WX is the remainder of the whole circle to the sum of the arc angles WZ and ZX :

arc angle WX = 360 - 135 - 51 = 174°

Answer:

B: y ≥ 2r-4.

Step-by-step explanation:

To solve for y, we need to isolate y on one side of the inequality. First, we can simplify the left side of the inequality by dividing both sides by 2:

2x - y ≤ 4

Then, we can subtract 2x from both sides to get:

-y ≤ -2x + 4

Finally, we need to isolate y by multiplying both sides by -1 and flipping the direction of the inequality:

y ≥ 2x - 4

Now we can see that the equivalent inequality is option B: y ≥ 2r-4.

If TV cable company has 2400 subscribers who are each paying ​$16 per month, charging $52 per month will yield a maximum revenue of $98,304.

To find the rate that will yield the maximum revenue, we can use the formula:

r = -b / 2a

where r is the rate, a is the coefficient of the quadratic term, and b is the coefficient of the linear term in the revenue equation.

The revenue equation is:

R = (2400 + 120x)(16 - 0.5x)

Expanding and simplifying, we get:

R = -0.5x^2 + 52x + 38400

So, a = -0.5 and b = 52. Plugging these values into the formula, we get:

r = -52 / 2(-0.5) = 52

This means that the company should charge $52 per month to maximize revenue. To find the maximum revenue, we can plug this value into the revenue equation:

R = (2400 + 120(52))(16 - 0.5(52)) = $98,304

Answer: $5.40

Step-by-step explanation:

First, let's calculate the tax for each purchase and then find the total amount paid by Dave and James.

For Dave:

Basketball cost = $15

Tax = 8% of $15 = 0.08 * 15 = $1.20

Total amount paid by Dave = Cost + Tax = $15 + $1.20 = $16.20

For James:

Football cost = $20

Tax = 8% of $20 = 0.08 * 20 = $1.60

Total amount paid by James = Cost + Tax = $20 + $1.60 = $21.60

Now, let's find the difference between the amounts paid by Dave and James.

Difference = Amount paid by James - Amount paid by Dave = $21.60 - $16.20 = $5.40

So, the difference in the amounts paid by Dave and James, including tax, is $5.40.

Erin's capital gains are the sum of her long-term capital gains (LTCG) and short-term capital gains (STCG), which is $2,600 + $24,400 = $27,000.

In order for the account value to reach $91,000 in 12 years, Fwam would therefore need to invest $39,165.95, to the closest hundred dollars, assuming the interest rate is 5.9% compounded daily.

In exchange for using borrowed funds or assets, a borrower must pay the lender interest. It is charged for a certain duration of time, typically until the loan is fully returned, and is typically stated as a percentage of the amount borrowed. This fee is known as the interest rate. For instance, if a bank lends you $1,000 at a 5% annual interest rate, after a year of borrowing the money you would still owe the bank $50 more in interest. The creditworthiness of the borrower, the risk of the loan, and current market conditions are frequently used to establish the interest rate.

given

We know that Fwam expects the account to be worth $91,000 in 12 years and that the interest rate is 5.9% compounded daily in this situation.

We must convert the interest rate and the time period to the proper units before we can use the formula.

We begin by converting the 5.9% yearly interest rate to a daily rate:

daily rate is equal to (1 + 0.059/365)(365/365)-(1-1) = 0.00015999.

4,380 days in 12 years, or 365 days per year.

We can now enter the values into the formula to find P:

$91,000 = P × 2.3226

P = $39,165.95

In order for the account value to reach $91,000 in 12 years, Fwam would therefore need to invest $39,165.95, to the closest hundred dollars, assuming the interest rate is 5.9% compounded daily.

The quadratic function that models the height h of the ball after t seconds in flight is h(t) = -16t² + 70t + 3.5

A quadratic function is a type of function in algebra that involves a variable raised to the power of 2, or squared. The general form of a quadratic function is:

f(x) = ax² + bx + c

where f(x) represents the output of the function for a given input x, a, b, and c are constants that determine the shape and position of the function, and x is the input variable.

The graph of a quadratic function is a parabola, which is a curved shape that opens upwards if the coefficient a is positive, and downwards if the coefficient a is negative. The vertex of the parabola is the point at which the function reaches its minimum or maximum value, depending on the direction of the opening of the parabola. The x-coordinate of the vertex is given by:

x = -b/2a

The height h of the ball after t seconds in flight can be modeled by the quadratic function:

h(t) = -16t² + vt + s

where v is the initial velocity of the ball, s is the initial height of the ball, and -16 is the acceleration due to gravity in feet per second squared.

In this case, we know that the ball is hit with an initial velocity of 70 ft/s and is 3.5 ft off the ground, so we can substitute these values into the equation:

h(t) = -16t² + 70t + 3.5

Therefore, the quadratic function that models the height h of the ball after t seconds in flight is:

h(t) = -16t² + 70t + 3.5

Note that this function is only valid until the ball reaches its maximum height and starts falling back down to the ground.

The vertex is (4,1), and the parabola opens b since the coefficient of the squared term is negative. The axis of symmetry is x=4, and the domain is all real numbers. The range is (-∞, 1], since the maximum value is 1.

A parabola is a symmetrical U-shaped curve that can be formed by intersecting a cone with a plane parallel to one of its sides. It is a type of quadratic function, which can be expressed in the form of y = ax^2 + bx + c, where "a" is the coefficient of the squared term, "b" is the coefficient of the linear term, and "c" is the constant term.

f(x) = x²+8x-3

To complete the square, we need to add and subtract the square of half the coefficient of x:

f(x) = (x²+8x+16) - 19 --> (x+4)² - 19

So, the equation in vertex form is: f(x) = (x+4)² - 19.

The vertex is (-4,-19), and the parabola opens upwards since the coefficient of the squared term is positive. The axis of symmetry is x=-4, and the domain is all real numbers. The range is [-19, ∞), since the minimum value is -19.

f(x)=-2x² + 16x-31

To complete the square, we need to factor out the leading coefficient of -2, and then add and subtract the square of half the coefficient of x:

f(x) = -2(x² - 8x + 16) - 31 + 32 --> -2(x-4)² + 1

So, the equation in vertex form is: f(x) = -2(x-4)² + 1.

The vertex is (4,1), and the parabola opens downwards since the coefficient of the squared term is negative. The axis of symmetry is x=4, and the domain is all real numbers. The range is (-∞, 1], since the maximum value is 1.

The length of the ramp we need to build should be at least 38.61 feet to pass code.

In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.

We can use trigonometry to solve the problem. Let x be the length of the ramp we need to build. Then, the angle the ramp makes with the ground is given by:

sin(theta) = opposite/hypotenuse

where theta is the angle the ramp makes with the ground, opposite is the vertical increase of 10 feet, and hypotenuse is the length of the ramp x.

Solving for x, we get:

x = opposite/sin(theta) = 10/sin(15)

Using a calculator, we can evaluate sin(15) to be approximately 0.2588. Then, we can divide 10 by 0.2588 to get:

x ≈ 38.61
