Step-by-step explanation:

To create a perpendicular bisector, you need a compass, a straightedge, and a pencil. As well as the line segment AB drew down.

1> You start by opening the compass and stretching it to a width greater than half the length of AB.

2> Then you simply place one point of the compass on the line segments A. From here, you move the compass and draw arcs above and below the line AB.

3> Without moving the compass measure, remove it from point A and place it onto point B. You basically repeat step 2 by drawing arcs above and below the line again.

4> If you've done it right, the arcs should be in the middle, X and Y, and using a straightedge/ruler you draw a line that goes vertically through where they connect.

and that should be your perpendicular bisector using segment AB.

The maximum volume of the cylinder is approximately 1257 cubic centimeters.

The volume V of a right circular cylinder with radius r and height h is given by:

V = πr²h

Substituting the given expressions for the radius and height of the cylinder, we get:

V = πx²(800/πx - x)

Simplifying the expression, we get:

V = 800x - πx³

To find the maximum value of V, we need to find the value of x that maximizes V. We can do this by taking the derivative of V with respect to x, setting it equal to zero, and solving for x:

dV/dx = 800 - 3πx² = 0

3πx² = 800

x² = 800/3π

x ≈ 6.43

Substituting this value of x back into the expression for V, we get:

V ≈ 1257

The value of sin -1(square root 2/2) is π/4 or 45 degrees.

Inverse sine, also known as arcsine, is a trigonometric function that is the inverse of the sine function. It is denoted as sin^-1(x), where x is a number between -1 and 1.

The inverse sine function is used to find the angle in a right triangle that has a given sine value. In other words, if we know the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle, we can use the inverse sine function to find the measure of that angle.

The inverse sine function returns an angle in radians, which can be converted to degrees if needed. It has a domain of -1 ≤ x ≤ 1 and a range of -π/2 ≤ sin^-1(x) ≤ π/2.

Like other inverse trigonometric functions, the inverse sine function is a multivalued function. This means that for a given value of x, there can be multiple angles that satisfy sinθ = x. To address this, the principal value of the inverse sine function is defined as the angle between -π/2 and π/2 that satisfies sinθ = x.

The inverse sine function has many applications in mathematics, physics, engineering, and other fields. It is used in the calculation of angles in a variety of contexts, such as in the design of structures and in the analysis of wave phenomena. It is also used in calculus and other advanced mathematics courses to solve integrals and differential equations.

To see why, we can use the definition of the inverse sine function, which gives us the angle whose sine is equal to the input value. In this case, we have:

sin -1(square root 2/2) = θ

where sin(θ) = square root 2/2.

We know that the sine of 45 degrees (or π/4 radians) is also equal to square root 2/2. Therefore, we have:

sin(45 degrees) = square root 2/2

Taking the inverse sine of both sides gives us:

sin -1(square root 2/2) = 45 degrees = π/4

Answer:

The rates are not equivalent since Maria saves $0.50 more per month than Ralph.

Step-by-step explanation:

We can determine if two rates are equivalent by comparing the rates at which they save per month.

Maria's savings per month:

Both 50 and 4 can be divided by 2, which gives us 25/2.  As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.

Ralph's savings per month:

Both 60 and 5 can be divided by 5, which gives us 12.  Thus, Ralph saves $12 per month.

Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.

To find the number of dimes and quarters, you have 17 dimes and 34 quarters in your pocket , when there are 51 coins in your pocket.

To solve this problem, we can set up a system of equations using the given information. Let's use "d" to represent the number of dimes and "q" to represent the number of quarters.

We know that there are 51 coins in total, so we can write the equation: d + q = 51.

We also know that the total value of the coins is $10.20, which can be expressed as 10d + 25q (since dimes are worth 10 cents and quarters are worth 25 cents). So our second equation is: 10d + 25q = 1020.

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

Rearrange the first equation to solve for d: d = 51 - q.

Substitute this expression for d in the second equation: 10(51 - q) + 25q = 1020.

Simplify and solve for q: 510 - 10q + 25q = 1020.

Combine like terms: 15q = 510.

Divide both sides by 15: q = 34.

Now substitute this value back into the first equation to solve for d: d + 34 = 51.

Subtract 34 from both sides: d = 17.

Therefore, you have 17 dimes and 34 quarters.

The standard error is 0.0912.

The standard error (SE) is a measure of the precision of the sample mean estimate compared to the true population mean. To calculate the SE, we use the formula SE = standard deviation / square root of sample size.

In this scenario, the population parameter is 0.7, and the sample size is 30. If we assume that the sample mean is an unbiased estimator of the population mean, then the SE can be calculated using the above formula. However, we do not know the standard deviation of the population, so we use the sample standard deviation as an estimate.

Assuming the sample is large enough to assume normality, the formula becomes SE = \(\sqrt{(0.7*0.3)/30}\)   = 0.0912. Therefore, the standard error for a sample size of 30 is 0.0912. This means that if we were to take multiple samples of size 30 from the same population, the standard deviation of the means of those samples would be around 0.0912 away from the population parameter of 0.7 on average.

Answer:

Vertex: \((-\frac{1}{3},-\frac{25}{3})\)

Y-intercept: \((0,-8)\)

Step-by-step explanation:

The x-coordinate of the vertex would be \(x=\frac{-b}{2a}\) and the y-coordinate of the vertex is whatever the output is given the value of x.

Therefore, the x-coordinate of the vertex is \(x=\frac{-b}{2a}=\frac{-2}{2(3)}=\frac{-2}{6}=-\frac{1}{3}\)

This means the y-coordinate of the vertex is \(y=3x^2+2x-8=3(-\frac{1}{3})^2+2(-\frac{1}{3})-8=3(\frac{1}{9})-\frac{2}{3}-8=\frac{1}{3}-\frac{2}{3}-8=-\frac{1}{3}-8=-\frac{1}{3}-\frac{24}{3}=-\frac{25}{3}\)

So, the vertex is \((-\frac{1}{3},-\frac{25}{3})\)

The y-intercept of a function is the y-value at which x=0, or the y-value when the function crosses the y-axis. Therefore, if we plug x=0 into the function, we see that \(h(0)=3(0)^2+2(0)-8=0+0-8=-8\), so our y-intercept is -8 or (0,-8).

The Magan has more money in her account than Myesha by $450,189 (rounded to the nearest dollar).

Compound interest is a sort of interest that is computed on both the principal—the amount borrowed or invested at the start—and the interest that has accrued over time.

For Magan's account:

Principal amount (P) = $210, Interest rate (r) = 95% = 0.95

Number of compounding periods (n) per year = 4 (quarterly),

Time (t) = 9 years

Amount in Magan's account after 9 years would be: (compound interest)

\(A = P(1 + \frac{r}{n} )^{nt}\)

   = $210 × (1 + 0.95/4)⁴*⁹

   = $210 × (1.2375)³⁶    =  $210 × 2145.98

A = $450,657 (rounded to the nearest cent)

For Myesha's account:

Principal amount (P) = $210, Interest rate (r) = 9% = 0.09, time is same

The amount in Myesha's account after 9 years would be:

\(A = P(1 + \frac{r}{n} )^{nt}\)

A = $210 × (1 + 0.09/4)⁴*⁹  = $468 (rounded to the nearest cent)

The difference in the amounts is = $468 - $450,657 = -$450,189

This means that Magan has more money in her account than Myesha by $450,189 (rounded to the nearest dollar).

Magan invested $210 in an account that offers a 95% interest rate. Let me provide a brief explanation of the situation.
When Magan invests $210 in the account, the bank or financial institution agrees to pay an interest rate of 95% annually on the invested amount. Interest is essentially the cost of borrowing money, and in this case, it's the reward Magan receives for lending their funds to the bank.
To calculate the amount of interest earned after one year, you would multiply the principal amount ($210) by the interest rate (95%).

In this case, it would be\( $210 * 0.95 = $199.50\).

This means that after one year, Magan would have earned $199.50 in interest on their initial investment.
Adding the interest earned to the original investment, Magan's account balance after one year would be

\( $210 + $199.50 = $409.50.\)

It's important to note that this calculation assumes that the interest is only compounded annually. If the interest were compounded more frequently, the final balance would be different.

The actual consumer spending at a price of $27 per unit is $268.26.

Substitute the given price into the supply equation to get the corresponding quantity supplied:

p = q + 10

27 = q + 10

q = 17

Substitute q = 17 into the demand equation to get the corresponding price:

4q² + p² = 1405

4(17)² + p² = 1405

p² = 1405 - 1156

p² = 249

p = 15.78
