The net that represents this solid figure is diagram D.

A solid figure is a three-dimensional geometric shape that has length, width, and height. It is also called a three-dimensional or 3D figure. Some examples of solid figures include cubes, spheres, cylinders, cones, and pyramids.

Solid figures are different from two-dimensional shapes, which only have length and width. In contrast, solid figures have depth or thickness, making them more complex and interesting.

Solid figures can be classified based on their properties, such as the number of faces, vertices, and edges they have. For example, a cube has six faces, eight vertices, and 12 edges, while a sphere has no faces, vertices, or edges.

In this case, it has 2 squares and 4 rectangles. The appropriate diagram is D

Multiply by 15 on both sides, subtract by 10 on both sides, and divide by 5 on both sides to get x=10

Answer:

a) r = 9.7 m

Step-by-step explanation:

      CD = CE + ED

            = 9 + r +r

            = 9 + 2r

If a tangent and a secant are drawn from a common point outside the circle, then

                     CE * CD = CB *CB

               9 *  ( 9 + 2r) = 16 * 16       {Distributive property}

               9*9 + 9*2r   = 256

                   81 + 18r    = 256

Subtract 81 from both sides,

The correct statement regarding whether (8, √17) lies on the circle is given as follows:

Yes, the distance from the origin to the point (8,√17) is 9 units.

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, while the diameter of the circle is the distance between two points on the circumference of the circle that pass through the center. Hence, the diameter’s length is twice the radius length.

The parameters for this circle are given as follows:

Hence the equation is given as follows:

x² + y² = 81.

For point (8, √17), we have that:

8² + (√17)² = 81

64 + 17 = 81

81 = 81.

Hence the point lies on the circle.

Pearl's mortgage payment would be $678.47 per month.

A mortgage is a type of loan that is used to finance the purchase of real estate, such as a house or a piece of land. When a person takes out a mortgage, they borrow money from a lender (usually a bank or other financial institution) to buy the property, and they agree to pay back the loan over a set period of time, typically 15 to 30 years.

In the given question,

To calculate Pearl's mortgage, we need to first determine the amount of her down payment.

Down payment = 10% x $130,000

Down payment = $13,000

The amount that Pearl needs to finance with her mortgage is:

$130,000 - $13,000 = $117,000

To calculate the mortgage payment, we can use the formula for a fixed-rate mortgage:

Mortgage Payment = P * r * (1 + r)^n / ((1 + r)^n - 1)

Where:

P = Principal (amount borrowed)

r = Monthly interest rate (annual rate divided by 12)

n = Number of monthly payments (30 years x 12 months per year)

Monthly interest rate = 6.3% / 12 = 0.00525

Number of monthly payments = 30 years x 12 months = 360

Using these values, we can calculate the monthly mortgage payment:

Mortgage Payment = $117,000 * 0.00525 * (1 + 0.00525)^360 / ((1 + 0.00525)^360 - 1)

Mortgage Payment = $678.47 (rounded to the nearest cent)

Therefore, Pearl's mortgage payment would be $678.47 per month.

The sums, differences, product, and quotient of the functions and their domains are;

f(x) = √(16 - x^2), g(x) = √(x + 3)

f + g = √(16 - x^2) + √(x + 3)

Domain; [-3, 4]

f - g = √(16 - x^2) - √(x + 3)

Domain: [-3, 4]

f × g = √(16 - x^2) × √(x + 3) = √(-x³ - 3·x² + 16·x + 48)

f × g = √(-x³ - 3·x² + 16·x + 48)

Domain; [-3, 4]

f/g = √(16 - x^2)/√(x + 3) = √(16 - x^2)/(x + 3))

f/g = √(16 - x^2)/(x + 3))

Domai; [-3, 4] ∪ [1, 4]

f(x) = √(81 - x^q2), g(x) = √(x² - 16)

f + g = √(81 - x^2) + √(x² - 16)

Domain [-9, -4] ∪ [4, 9]

f - g = √(81 - x^2) - √(x² - 16)

Domain: [-9, -4] ∪ [4, 9]

f × g = √(81 - x^2) × √(x² - 16) = √(-x⁴ + 97·x² - 1296)

f × g = √(-x⁴ + 97·x² - 1296)

The sum of two functions is obtained by adding the values of the functions at each point.

The sum of two functions is obtained by adding the values of the functions at each point. The domain of the sum is the intersection of the domains of the two functions, In this case, the domain of f + g is [-3, 4]

The difference of two functions is obtained by subtracting the functions values at each point. The domain of the difference is the intersection of the domains of the two functions. In this case, the domain of f - g is [-3, 4]

The product of two functions is obtained by multiplying the values of the functions at each point. The domain of the product of the functions is the domain of the intersection of the domains of the two functions. The domain of f × g is  [-3, 4]

The quotient of two functions is obtained by dividing the values of the functions at each point. The domain of the quotient is the same as the domain of the intersection of two functions, excluding any points where the denominators is zero. The domain of f/g is [-3, -1] ∪ [1, 4].

For the given function the intercepts are:

x-intercept: x = -4

y-intercept: y = 12.

Here we have a table that defines a function, and we want to find the intercepts of said function.

We can assume it is linear, then the slope of the function will be given by:

a = (9 - 3)/(-1 + 3) = 6/2 = 3

The linear function is like:

y = 3x + b

To find the value of b we can replace the values of the last point on the table, x = 2 and y = 18.

18 = 3*2 + b

18 = 6 + b

18 - 6 = b = 12

The linear function is:

y = 3x + 12

The x-intercept is the value of x when y = 0

0 = 3*x + 12

-12 = 3x

-12/3 = x = -4

The parameter y(0) represents the initial population, hence when the population is doubled, we have that:

y(t) = 2y(0).

Then we must solve the exponential function for the variable t, applying the natural logarithm, which is the inverse of the exponential, as follows:

2y(0) = y(0)e^(0.0264t).

e^(0.0264t) = 2

Answer:

1.65 pints

Step-by-step explanation:

If Tara used 6.6 pints of white and blue paint combined, and 3/4 of that amount is white paint, then we can find the amount of white paint she used by multiplying 6.6 by 3/4:

6.6 x 3/4 = 4.95

So Tara used 4.95 pints of white paint to paint her bedroom walls.

To find out how much blue paint she used, we can subtract the amount of white paint from the total amount of paint:

6.6 - 4.95 = 1.65

Therefore, Tara used 1.65 pints of blue paint to paint her bedroom walls.

Answer:

The 440-yd race is longer than the 400-m race by 2.336 meters.

Step-by-step explanation:

We can convert the distance of the 440-yd race to meters using the conversion factor 1 yd = 0.9144 m:

440 yd = 440 x 0.9144 m/yd = 402.336 m

Therefore, the 440-yd race is 402.336 meters long.

On the other hand, the 400-m race is already in meters.

Comparing the two distances, we can see that the 440-yd race is longer than the 400-m race.

To find out by how much longer, we can subtract the length of the 400-m race from the length of the 440-yd race:

402.336 m - 400 m = 2.336 m

Therefore, the 440-yd race is longer than the 400-m race by 2.336 meters.
