-14n⁴ + 7n² + 8n + 7

Step-by-step explanation:

(8n - 3n⁴ + 10n²) - (3n² + 11n⁴ - 7)

= 8n - 3n⁴ + 10n² - 3n² - 11n⁴ + 7

= -3n⁴ - 11n⁴ + 10n² - 3n² + 8n + 7

= -14n⁴ + 7n² + 8n + 7

This is a theorem called Converse of Alternate Exterior Angles that states that <em>if two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel</em>. Moreover, this theorem is based upon the corresponding Angles Converse Postulate that states that<em> if two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel. </em>We don't need to prove this postulate, it's assume to be true. So our goal is to get corresponding angles congruent in order to use the corresponding Angles Converse Postulate,

Reason: Given

Statement: $\angle1\cong\angle2$

Reason: Def of vertical $\angle s$

Statement: $\angle1\:and\:\angle3 \ are \ vertical$

Reason: Def of vertical $\angle s$

Statement: $\angle1\cong\angle3$

Reason: Transitive Property

Statement: $\angle2\cong\angle3$

Reason: corresponding Angles Converse Postulate

Statement: $p\parallel q$

Please help me with thisss

Butoxors [25]

Answer:

Here we have the relation:

m = 140*h

Where m is the distance in miles, and h is time in hours.

And we want to complete a table like:

$\left[\begin{array}{ccc}in, h&out, m\\&\\&\\&\\&\end{array}\right]$

The way to complete this, is to evaluate the function:

m = 140*h

in different values of h, and then record both values of h and m in the table.

Let's use values of h that increase by 0.5, then:

if h = 0.5

m = 140*0.5 = 70

We have the pair: h = 0.5, m = 70

if h = 1

m = 140*1 = 140

We have the pair: h = 1, m = 140

if h = 1.5

m = 140*1.5 = 210

Then we have the pair h = 1.5, m = 210

if h = 2

m = 140*2 = 280

We have the pair: h = 2, m = 280

Now we can complete the table, and it will be:

$\left[\begin{array}{ccc}in, h&out, m\\0.5&70\\1&140\\1.5&210\\2&280\end{array}\right]$

Sidana [21]

Answer:

Step-by-step explanation:

Draw a picture of a cube and label the cube's side length, s. Prior to placing your order for more cardboard, tape, packing material, etc. your boss asked you to determine each of the following: a. Write an expression to determine the surface area of a cube-shaped box, SA, in terms of its side length, s (in inches).

The surface area of a cube of side length s is A = 6s^2; there are 6 sides each of area s^2.

If s is measured in inches, then A = 6x^2 inches^2.

b. Define a formula to determine the volume of a cube-shaped box, V, in terms of its side length, s, (in inches). Preview What are the units for the cube's volume?

The formula for the volume of a cube is V = s^3. In this case, V is measured in inches^3.

c. Given the formula for determining the volume of a 4 sphere is V = ar atrs, 3 (This is incorrect; the formula in question, for the volume of a sphere of radius r is V = (4/3)(pi)r^3. (1) We can solve this formula for r^3, and then for r:

3V = 4(pi)r^3 becomes r^3 = ------------

4(pi)

and so the formula for the radius of a sphere whose volume is 87 inches^3

∛(3V) ∛3*87 in^3

r = ------------ = ------------------

∛(4pi) ∛(4pi)

(2) The volume of the sphere when r = 5.9 in is:

4(3.14) 205.38 in³

(4/3)(pi)r^3 = (4/3)(pi)(5.9 in)³ = --------- = --------------------- = 67.46 in³

3 3

(3) V = (4/3)(pi)r³

Please share the possible answer choices. Basically, you must find the volume twice: once for a radius of 4 in and once for a radius of 2 in. Then subtract the smaller from the larger. The numerical result is the desired answer.
