To find the surface area of a rectangular prism, we can use the following formula:

[tex]SA=2(lw+lh+wh)[/tex]

We're given:

Plug the given measurements into the formula for surface area:

[tex]SA=2(lw+lh+wh)\\SA=2[(4)(1)+(4)(3)+(1)(3)]\\SA=2(4+12+3)\\SA=2(19)\\SA=38[/tex]

Therefore, the surface area of the rectangular prism is 38 yd².

38 square yards

A shape can only be classified as a polygon if:

We can see that the figure is opened. Therefore, the shape is not a polygon. According to (2), to classify a shape, a polygon, the shape must not be opened.

Therefore, this shape is not a polygon.

This shape is a polygon because it has no curves, it is not opened, and the sides of the shape are not forming an intersection.

Therefore, this shape is a polygon.

This figure has a side length intersecting another side length. Therefore, this figure is not a polygon. According to (3), to classify a shape, a polygon, the sides of the shape must not intersect each other.

Therefore, this shape is not a polygon.

This figure is not a polygon because a side length of the figure is curved. According to (1), To classify a shape, a polygon, there must be no curves in the shape.

Therefore, this shape is not a polygon.

Hence, Option B is correct.

Answer:

As [tex]x[/tex] approaches infinity [tex]f(x)[/tex] approaches negative infinity.

Step-by-step explanation:

As you can see in the graph as [tex]x[/tex] grows larger in the negative direction, the [tex]y[/tex] increases in the negative direction too.

Thus:

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

Step-by-step explanation:

Corresponding angles of similar figures are congruent.

Angles with vertex of same order number are corresponding.

Answer:

m∠U =97°

m∠V = 124°

m∠T = 102°

Step-by-step explanation:

As  TUVWX ~ BCDEF  then the corresponding interior angles are the same.

Therefore:

m∠T = m∠B = 102°

m∠U = m∠C = 97°

m∠V = m∠D = 124°

m∠W = m∠E = 101°

m∠X = m∠F = 116°

Answer:

8/5x

Step-by-step explanation:

it's (-4,-4) and (1,4) so you subtract the y's getting 8. then you subtract the x's getting 5. y/x is the rule so you would get 8/5 or 8/5x as the slope/distance between points.

Find the value of y when x = 5

Answer:

A.  y = 9.8x

B.  49 newtons

Step-by-step explanation:

Part A

Definition of the given variables:

If the gravitational force is directly proportional to the mass, then:

   [tex]y \propto x \implies y=kx \quad \textsf{(for some constant k)}[/tex]

Given:

Substitute the given values into the equation and solve for k:

[tex]\implies 19.6=2k[/tex]

[tex]\implies k = 9.8[/tex]

Therefore, the direct variation equation is:  [tex]y=9.8x[/tex]

Part B

To find the gravitational force of an object with mass of 5 kg, substitute x = 5 into the found equation from part A and solve for y:

[tex]\implies y=9.8(5)[/tex]

[tex]\implies y=49\:\: \sf newtons[/tex]

Answer:

$3.49

Step-by-step explanation:

If 1 yard = 3 foot

then A 2-yard piece of twine = 6-foot piece of twine.

20.94 per foot is 3.49

as 20.94/3.49.

thus the price per foot is $3.49

An equation to represent the total cost of a job that takes "x" hours is "total cost = $50 + ($150 × x)". The situation can be described as linear.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the cost of consulting is $50, while the cost of labour is $150 per hour.

A.) An equation to represent the total cost of a job that takes "x" hours.

Total cost = $50 + ($150 × x)

B.) Total cost is the labour works for 40 hours,

Total cost = $50 + ($150 × 40) = $6,050

C.) As found above the cost of working 40 hours is $6,050, therefore, the amount of $5,000 will not be enough.

D.) The situation can be described as linear.

Nominal Interest Rate: Does not consider inflation  provides a sense of  purchasing power

Real Interest Rate: It describes the stated interest rate on  an account  and also considers inflation

Step-by-step explanation:

Real interest rate  can be defined as the Nominal interest rate minus the inflation rate.

Nominal Interest Rate is the interest rate without taking into account the inflation

Answer:

NOMINAL INTEREST RATE:

1. The stated interest rate on an account.

2. Does not consider inflation.

3. Reflects the actual monetary amount earned

Answer:

(1, 0 ) and (3, 6 )

Step-by-step explanation:

we are looking in the table for values of x that give both f(x) and g(x) the same value.

x = 1 → f(x) = g(x) = 0

x = 3 → f(x) = g(x) = 6

then the solutions to f(x) = g(x) are

(1, 0 ) and (3, 6 )

Answer:

1

3

Step-by-step explanation:

According to the table :

f(1) = 0 = g(1) ⇒ 1 is a solution to the equation f(x) = g(x)

f(3) = 6 = g(3) ⇒ 3 is a solution to the equation f(x) = g(x)

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The volume of the cylinder with a radius of 5 inches and a height of 16 inches is 1256 in³.

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.

Given the radius of the cylinder is 5 inches, while the height is 16 inches, therefore, the volume of the cylinder will be,

Volume of the cylinder = πr²h = π×(5)²×16 = 1,256.637 in³ ≈ 1,256 in³

Hence, the volume of the cylinder with a radius of 5 inches and a height of 16 inches is 1256 in³.
