Answer:

D. The student didn't put parentheses around the -2 when finding the discriminant.

Answer:

PV = PMT x [(1 - (1 + r/n)^(-nt)) / (r/n)]

Where:

PV is the present value of the loan (maximum price of the boat that Ryan can afford)

PMT is the monthly payment that Ryan can afford ($300)

r is the annual interest rate (11%)

n is the number of times interest is compounded per year (12, for monthly payments)

t is the number of years for the loan (8)

Plugging in the numbers, we get:

PV = $300 x [(1 - (1 + 0.11/12)^(-12*8)) / (0.11/12)]

PV = $24,598.82

Therefore, the maximum price for a boat that Ryan's budget can afford is $24,598.82, rounded to the nearest hundred dollars, is $24,600.

Answer:

17.36

Step-by-step explanation:

The formula to find the circumference of a circle is:

Circumference = π x Diameter

Where π (pi) is a mathematical constant approximately equal to 3.14159.

So, if the diameter of the circle is 5.52, the circumference can be calculated as:

Circumference = π x 5.52

Circumference ≈ 17.36 (rounded to two decimal places)

Therefore, the circumference of a circle with a diameter of 5.52 is approximately 17.36 units.

From the given triangle figure the value of y is 4.5.

The given figure is -

Now we have to find the value of 'y' from the given triangle.

Triangle ABC is right angled triangle with right angle at point A.

So, ∠B + ∠C = 90° ......... (i)

Again, triangle ADB is a right angled triangle with right angle at point D.

So, ∠DAB + ∠B = 90° .......... (ii)

Comparing (i) and (ii) we can say that,

∠DAB = ∠C

Again, triangle ADB is a right angled triangle with hypotenuse AB.

By Pythagoras theorem,

AD² + DB² = AB²

AB² = 3² + 2² = 9 + 4 = 13

AB = √13

Hence triangle ABC and triangle ADB are two similar triangles. So,

AB/DB = CB/AB

√13/2 = (y + 2)/√13

2(y + 2) = √13*√13

2y + 4 = 13

2y = 13 - 4 = 9

y = 9/2 = 4.5

So the value of y is 4.5.

Answer:

$2102.48.

Step-by-step explanation:

FV=PV⋅(1+r)n

where:

FV is the future value

PV is the present value

r is the interest rate per period

n is the number of periods

In your case, the present value is 2000, the interest rate per year is 0.03, and the number of years is 18/12 = 1.5. However, since the formula uses the interest rate per period and the number of periods, you need to convert them to match the frequency of compounding. For example, if the interest is compounded monthly, then you need to divide the annual interest rate by 12 and multiply the number of years by 12. Let’s assume that the interest is compounded monthly in this case. Then, you can plug in the values into the formula and get:

FV=2000⋅(1+120.03​)1.5⋅12

Using a calculator, you can simplify this expression and get:

FV=2000⋅1.031518

FV=2000⋅1.0512

FV=2102.48

As a result, the cylinder's surface area at a height of 2 feet and a radius of 3 feet is roughly 37.699 square feet.

The entire area occupied by the cylinder's flat, round bases and its curved surface is referred to as the surface area of a cylinder. Since the cylinder's base is a circle, it may be stated that it is the sum of the area of a circle and the area of the curved surface, which is a rectangle.

A = 2rπh, where r is the cylinder's radius and h is its height, is the formula for a cylinder's lateral surface area1.

Use the formula to determine the surface area of a cylinder with a height of 2 feet and a radius of 3 feet.

The formula for the lateral surface area of a cylinder, A = 2rh, can be used to determine the surface area of a cylinder with a height of two feet and a radius of three feet.

Al = 2(3)π(2) = π12 square feet is the result of replacing r = 3 feet and h = 2 feet in the previous formula.(π=3.14)

Using the fact that the triangles are similar, we can see that x = 2

The triangles are similar because lines WR and RT have the same slopes compared to SR and RV.

Now, we know that there is a scale factor between them, so if that scale factor is k, we can write:

8*k = 10

k = 10/8

k = 1.25

Then:

(x + 6)*1.25 = 2x + 6

Now we can solve this for x.

1.25x + 7.5 = 2x + 6

7.5 - 6 = 2x - 1.25x

1.5  = 0.75x

1.5/0.75 = x =2

An equation in math is an expression that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between each of the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The sign and only one variable are frequently the same. as in, 2x - 4 equals 2, for instance.

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. The true statements are the center of the circle lies on the x-axis and the standard form of the equation is (x - 1)^2 + y^2 = 3. So, the correct answers are B and D.

To determine which statements are true about the circle with equation x^2 + y^2 - 2x - 8 = 0

First, we can rewrite the equation by completing the square

(x^2 - 2x + 1) + y^2 = 9

(x - 1)^2 + y^2 = 3^2

Therefore, the center of the circle is at (1, 0), which lies on the x-axis.

The radius of the circle is sqrt(3), which is not equal to 3, so the statement "The radius of the circle is 3 units" is false.

Since the center of the circle is on the x-axis, the statement "The center of the circle lies on the y-axis" is false.

The standard form of the equation is (x - 1)^2 + y^2 = 3, which is true.

Finally, the radius of the circle whose equation is x^2 + y^2 = 9 is 3 units, which is not the same as the radius of the given circle. Therefore, the statement "The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9" is false.

Step-by-step explanation:

You want the values of m and c for the equation y = mx + c that describes the line on the graph.

The coefficient 'm' in the equation y = mx + c is the slope of the line. It is the ratio of the "rise" to the "run". The "rise" is the vertical distance from one point to another on the line. The "run" is the corresponding horizontal distance between the points.

For finding these values, it is convenient to locate points on the graph that cross grid line intersections. These are circled in the attachment.

The slope (m) of this line is ...

  m = 5/1 = 5

The constant 'c' in the equation y = mx + c is the y-intercept of the line. It is the value of y when x=0. On the graph, it is the y-coordinate of the point where the line crosses the y-axis.

The line on this graph crosses the y-axis at y = -2.

The value of 'c' is -2.

The equation of the line is y = 5x -2.

__

Additional comment

You can find the values of "rise" and "run" from coordinates, or by counting grid squares on the graph. Often, counting the grid lines is easier.

Here, the "rise" is 3 -(-2) = 5, the difference of y-coordinates of the circled points.

The "run" is 1 -0 = 1, the difference of the corresponding x-coordinates of the circled points.

The slope is rise/run = 5/1 = 5.

Therefore, the solutions of the given equation in the interval [0, 21) are 0, 2π, and 3π/2. We write the answer in terms radians of π and separate the solutions with commas:

0, 2π, 3π/2.

Trigonometric identities are equations that relate different trigonometric functions to each other. These identities are true for all values of the variables involved in the equation. There are several different types of trigonometric identities, including:

Pythagorean identities: These are equations that relate the squares of the three basic trigonometric functions: sine, cosine, and tangent. The most common Pythagorean identity is:

[tex]sin^2 \alpha + cos^2 \alpha = 1[/tex]

This identity is true for all values of [tex]\alpha[/tex].

We start by using the trigonometric identity:

sin²θ + cos²θ = 1

Rearranging it, we get:

sin²θ = 1 - cos²θ

So, we can rewrite the given equation as:

sin²0 = sin²0 + cos²0 - cos0

Simplifying further, we get:

cos0 = cos²0

If Santiago has been approved for a mortgage up to $195,000 and the conventional loan requires a 20% down payment, then his down payment will be:

Down payment = 20% * $195,000

Down payment = $39,000

Therefore, if Santiago buys a house for the maximum amount he has been approved for, he will need to make a down payment of $39,000.

To calculate how much house Santiago can afford, we need to subtract the down payment from the total amount he has been approved for:

Maximum home price = Total mortgage amount - Down payment

Maximum home price = $195,000 - $39,000

Maximum home price = $156,000

Therefore, Santiago can afford a home up to a maximum price of $156,000.
