By using a translation rule, the coordinates of C' are (- 1, - 2). (Correct choice: E)

Triangles are defined by the locations of its three vertices on Cartesian plane and we must find the locations of the images of the three vertices after applying a translation rule. In this case, we must translate each vertex  2 units upward and 4 units to the right. The general translation formula is described below:

P'(x, y) = P(x, y) + T(x, y)

Where:

If we know that C(x, y) = (- 5, - 4) and T(x, y) = (4, 2), then the location of the image of point C is:

C'(x, y) = (- 5, - 4) + (4, 2)

C'(x, y) = (- 1, - 2)

The coordinates of C' are (- 1, 2).

The total surface area of the pyramid (a) is  624.32 cm² , and of pyramid (b) is 265.6 m²  .

The Total Surface Area of the Pyramid with pentagon base can be calculated using the formula

TSA = 5/2*b(a+s) ,

where b is the base length (side of pentagon)

s is the slant height ,

a is the apothem

and the Total Surface Area of the Pyramid with square base can be calculated using the formula .

TSA = b² + 2bs

where , b is the base and

s is the slant height .

Pyramid (a)

we can see from the figure that ,the pyramid has a pentagon base ,

So, the TSA will be 5/2*b(a+s) ,

in the figure , given that height =12 cm , apothem = 7.8cm

we find the slant height by Pythagoras theorem

(slant height)²=(height)²+(apothem)²

(slant height)² = 12² + 7.8²

(slant height) = √(12² + 7.8²)

(slant height) = √(144+60.84)

(slant height) = 14.3 cm

Substituting in TSA formula , TSA = 5/2*b(a+s)

we get ,

TSA = 5/2*11.3(7.8+14.3)

= 2.5*11.3(22.1)

= 28.25*22.1

=624.32 cm²

Pyramid (b)

we can see from the figure that ,the pyramid has a square base ,

So, the TSA will be b² + 2bs,

in the figure , given that height =12 m , apothem = 4 m

we find the slant height by Pythagoras theorem

(slant height)²=(height)²+(apothem)²

(slant height)² = 12² + 4²

(slant height) = √(12² + 4²)

(slant height) = √(144+16)

(slant height) = 12.6 m

Substituting in TSA formula , TSA = b² + 2bs

we get ,

TSA = 8² + 2*8*12.6

= 64 + 16*12.6

= 64 + 201.6

= 265.6 m²

Therefore , the total surface area of the pyramid (a) is 624.32 cm²  , and of pyramid (b) is 265.6 m² .

The triangle is Isosceles and Acute.

From the given data, the coordinates of the three points of the triangle are, A(2, 3), B(8, 3), and C(5, 6).

applying the distance formula, D = √((x2-x1)²+(y2-y1)²) the distance AC and BC are obtained as 3√2 and the distance AB as 2√3.

From this, it can be concluded that AC=BC≠AB.

thus since two of the sides, AC and BC are equal and the third side AB is not equal to AC and BC hence the given triangle is an isosceles triangle.

To check whether the given triangle is right, acute.

A right triangle is a triangle with one of its angles equal to 90 degrees.

An acute triangle is a triangle with all three of its angles less than 90 degrees.

An obtuse triangle is a triangle with at least one of its angles greater than 90 degrees.

To check whether the given triangle is right, acute, or obtuse we use the law of cosines.

To find the angle of a triangle given 3 of its sides, let the angle between the sides AB and AC be A then,

cos(A) =  (AC² + AB² − BC²)÷(2×AB×AC).

cos(A) = (3√2² + 2√3² - 3√2²)÷(2×2√3×3√2) =2÷√6

[tex]cos^{-1}[/tex](2÷√6) = 39.182.

Let the angle between the sides AB and BC be B then,

cos(B) =  (BC² + AB² − AC²)÷(2×AB×BC).

cos(B) = (3√2² + 2√3² - 3√2²)÷(2×2√3×3√2) =2÷√6

[tex]cos^{-1}[/tex](2÷√6) = 39.182.

Let the angle between the sides AC and BC be then,

cos(C) =  (AC² + BC² − AB²)÷(2×AC×BC).

cos(C) = (3√2² + 3√2² - 2√3²)÷(2×3√2×3√2) =2÷3

[tex]cos^{-1}[/tex](2÷3) = 53.544.

Since all the angles A, B, and C is less than 90 degrees the triangle is acute.

The hiking trail that has the least change in elevation, related to sea level, is:

Southern Moon.

The change in altitude of each trail is calculated as the subtraction of the highest altitude by the lowest altitude, that is:

Change in elevation = highest altitude - lowest altitude.

For Eastern Point, the change is given as follows:

Change = 78 - (-85) = 78 + 85 = 163 feet.

(subtracting by a negative is the same as adding to the positive of the number).

For Northern Star, the change is given as follows:

Change = 34 - (-150) = 34 + 150 = 184 feet.

For Southern Moon, the change is calculated as follows:

Change = 48 - (-62) = 48 + 62 = 110 feet.

The smallest amount is of 110, hence Southern Moon has the least change in elevation relative to sea level.

Step-by-step explanation:

This appears to be a repeating sequence of four numbers:

72, 3, 28, 42

so the missing 4 numbers must be as above

Answer:

x = 40

Step-by-step explanation:

We just have to manipulate the terms, putting each term that has the variable "x" on one side of the equation like this:

5x + 8 = 7x - 72​

5x - 7x = - 72 - 8​

-2x = -80

x = -80/--2

x = 40

Answer:

x = 40

Step-by-step explanation:

Given equation:

[tex]5x+8=7x-72[/tex]

Add 72 to both sides:

[tex]\implies 5x+8+72=7x-72+72[/tex]

[tex]\implies 5x+80=7x[/tex]

Subtract 5x from both sides:

[tex]\implies 5x+80-5x=7x-5x[/tex]

[tex]\implies 80=2x[/tex]

Divide both sides by 2:

[tex]\implies \dfrac{80}{2}=\dfrac{2x}{2}[/tex]

[tex]\implies 40=x[/tex]

Therefore, the solution to the given equation is x = 40.

The coordinates of the vertices of triangle A'B'C' after a reflection over the y-axis to triangle ABC are: C. A' = (3, -3), B' = (6, -3), C' = (5, -6), D' = (0, -6).

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (x, y).

By applying a reflection over the y-axis to triangle ABC, the coordinates of the vertices of the image triangle A'B'C' include the following:

(x, y)                    →            (x, y)

Point A = (3, -3)   →  Point A' = (3, -3)

Point B = (6, -3)   →    Point B' = (6, -3)

Given vector v as a linear combination of the standard unit vectors i and j would be, vec v = 10 i -4 j

In this question, we have been given a vector whose initial point is (-2, -1) and the final point is (8, -5)

We need to write vector v as a linear combination of the standard unit vectors i and j.

Let (x1, y1) = (-2, -1) and (x2, y2) = (8, -5)

We know that for vector A having initial point (x1, y1) and terminal point (x2, y2), a linear combination of the standard unit vectors i and j is:

vec A = (x2 - x1)i + (y2 - y1)j

So, for given vector it would be,

vec v = (x2 - x1) i + (y2 - y1) j

vec v = (8 - (-2)) i + (-5 - (-1)) j

vec v = (8 + 2) i + (-5 + 1) j

There are 29 nickels and 12 dimes in the piggy bank.

In this question, we have been given a piggy bank contains 2.65$ in nickels and dimes.

We need to find the number of nickels and dimes if the number of nickels is 7 less than three times the number of dimes.

Let x be the number of nickels and y be the number of dimes.

We know that, 1 dollar = 20 nickels

and 1 dollar = 10 dimes

So, we get an equation

0.05x + 0.1y = 2.65                   ...........(1)

Also the number of nickels is 7 less than three times the number of dimes.

x = 3y - 7                      .................(2)

Substitute above value of x in equation (1)

0.05(3y - 7) + (0.1)y = 2.65

0.15y - 0.35 + 0.1y = 2.65

0.25y = 2.65 + 0.35

0.25 y = 3

y = 12

Substitute above value of y in equation  (2)

x = 3(12) - 7

x = 29
