The pair of triangles that can be used to show that the slope of line a is same everywhere is upper half triangles

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h.

The pair of triangles in choice C (shown in the figure below) demonstrates that line a has a constant slope throughout.

Let's investigate:

Rise/run = slope

Regarding the initial lower triangle:

Rise = 3.5

Run = 4.5

Slope = 3.5/4.5 ≈ 0.8

For the upper second traingle:

Rise = 4

Run = 5

Slope = 4/5 = 0.8

As a result, it demonstrates that the graph's line's slope is constant throughout.

We are given a sequence. A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important. It has members, just like a set. The length of the sequence is defined by the number of elements. The given sequence consists of factorials. The product of all positive integers less than or equal to n, denoted by n!, is the factorial of a non-negative integer n. We need to find the exponential generating function for the given sequence.

An angle in Euclidean geometry is the figure produced by two rays, called the sides of the angle, that have a common termination, called the vertex of the angle. Angles formed by two rays lie in the plane containing the rays. Angles are also generated by the intersection of two planes. These are referred to as dihedral angles. Two intersecting curves can also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection.

The cost of materials for the least expensive such container is $327.081  .

In the question ,

it is given that

the volume of the container = 10 m³ .

let the width of the container = x

so , the length of the container = 2x

So , base area = 2x*x = 2x²

cost for base = $20

cost for the sides = $12

Since the volume is 10 m³

Volume = base area *  height

10 = 2x² * h

h = 10/2x²

h = 5/x²

The cost of making the container

cost of base = 2x² * (20) = 40x²

cost of sides = [2*2x*(5/x²) + 2*x*(5/x²)](12)

= 360/x

the total cost of the container [tex]=[/tex] cost of base [tex]+[/tex] cost of sides

= 40x² + 360/x

= 40( x² + 9/x)

to get the minimum cost , we differentiate with respect to x and equate to 0

= 40 ( 2x - 9/x²)

2x - 9/x² = 0

2x³ = 9

x³ = 9/2

x³ = 4.5

x = 1.651

Substituting x in the cost equation ,

we get

Cost = 40x² + 360/x

= 40(1.651)² + 360/(1.651)

= 109.032 + 218.049

= 327.081

Therefore , The cost of materials for the least expensive such container is $327.081  .

The slope of the line that passes through (3,4) and (2,-1) is 5/1 as a fraction

From the question, the points are given as

(3,4) and (2,-1)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) = (3,4) and (2,-1)

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (3,4) and (2,-1)

Substitute the known values in the above equation

So, we have the following equation

Slope = (-1 - 4)/(2 - 3)

Evaluate the difference in the above equation

So, we have the following representation

Slope = -5/-1

Lastly, we evaluate the quotient

So, we have

Slope = 5

The solution is to be in fraction form

So, we have

Slope = 5/1

Hence, the slope of the line is 5/1

If a washer and dryer cost $750 and the cost of the washer is two times the cost of the dryer, then the cost of the dryer $250

The total cost of a washer and dryer combined = $750

The cost of the dryer = x

The cost of the washer is two times the cost of the dryer.

The cost of the washer = 2x

Then the equation will be

x + 2x = 750

Add the like terms of the equation

3x = 750

Move 3 to the right hand side of the equation

x = 750/3

x = $250

Hence, if a washer and dryer cost $750 and the cost of the washer is two times the cost of the dryer, then the cost of the dryer $250

Expression equivalent to log 9⁵ is 5 log9.

Equivalent is not the same as equal in mathematics. While equivalent indicates similar but not the same, equal means the same in all respects. For instance, 1 + 1 is equivalent to 2, even if 2 is said to be equal to 2. Equivalent value or dated value refers to the value of an original sum at any given moment. The original amount and interest accrued up to the dated value date are combined to create the comparable payment. Money amounts are not directly comparable if they are payable or due at separate times.

Answer:

length = 13 cm and width = 14 cm

Step-by-step explanation:

let n be the length then n + 1 is the width

the perimeter (P) of a rectangle is calculated as

P 2(l + w) ← l is length and w is width

given P = 54 , then

2(n + n + 1) = 54 ( divide both sides by 2 )

2n + 1 = 27 ( subtract 1 from both sides )

2n = 26 ( divide both sides by 2 )

n = 13

n + 1 = 13 + 1 = 14

length = 13 cm and width = 14 cm

a) The bearing of Wellington from Gisborne is 232°

b) The bearing of Wellington from Auckland is  175.37°

We are given that AW = 410 km and GW = 400 km.

a) AG  is a transversal intersecting two parallel lines N₁A and N₂B and ∠N₁AG = 115°.

Thus;

∠AGN₂ = 180 − 115 = 65°  

since the sum of the interior angles on the same sides of the transversal intersecting two parallel lines are supplementary.

Thus;

∠N₂GW = 65 + 63 = 128°.

The reflex angle;

∠N₂GWW = 360 − 128° = 232°

b) In  △AGW, we can say that by the sine rule;

(sin∠WAG)/WG = (sin∠AGW)/AG  

Plugging in the relevant values;

(sin∠WAG)/400 = (sin∠63°)/410

Solving for ∠WAG gives; ∠WAG = 60.37°

The expression that can be used to represent the amount of sodium per serving in milligrams in the new soup can be computed as follows;

Old soup amount of sodium = x milligram

The new soup contains 33% less sodium per serving than the old soup recipe.

Therefore,

amount of sodium per serving in the new soup = x - 33% of x

amount of sodium per serving in the new soup = x - 33 / 100 x

amount of sodium per serving in the new soup = x - 0.33x

Therefore,

amount of sodium per serving in the new soup = x(1 - 0.33)
