Write the formula for a function d(x) that describes the distance between the point P and a point (x,y) on the line. You final answer should only involve the variable x. Then d(x) =

Answers

Answer 1
Answer:

Answer:

d(x) = √[(x - 2)² + (3x - 1)²]

Step-by-step explanation:

The distance between two points with coordinates (x₁, y₁) and (x₂, y₂) is given as

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

So, the distance between point (2,0) and a point (x,y)

d = √[(x - 2)² + (y - 0)²]

d = √[(x - 2)² + (y)²]

But the point (x,y) is on the line y = 3x - 1

We can substitute for y in the distance between points equation.

d(x) = √[(x - 2)² + (3x - 1)²]

What is the surface area of the square pyramid represented by the net? Enter your answer in the box. cm² An unfolded square base pyramid with sides of the base being seven centimeters and the length from the base to the tip is nine centimeters.

Answers

The surface area of the square pyramid represented by the net is 175 cm².

Given is a net of the square pyramid.

A square pyramid has the base of the pyramid being the square and four triangular lateral faces.

Given that,

An unfolded square base pyramid with sides of the base being seven centimeters and the length from the base to the tip is nine centimeters.

Base length, a = 7 cm

Slant height of the pyramid, l = 9 cm

Surface area = a² + 2al

                     = 7² + (2 × 7 × 9)

                     = 49 + 126

                     = 175 cm²

Area of the base = 7 x 7 = 49 cm²

Area of the 4 triangles = 4 x [ 1/2 x 7 x 9]
Area of the 4 triangles = 4 x 31.5
Area of the 4 triangles = 126 cm²

Total Surface Area = 49 + 126 = 175 cm²

Answer: Total Surface Area = 175 cm²

The answer to question one is $5.39. I got this answer by adding 16.49 and 1.62 to see how much she had to pay for the jeans and the tax which is 18.11. Then I subtracted 28.69 by 18.11 so I could find out how much money was for both of the jeans which is 10.78. Last I divided by 2 because there are 2 jeans which the answer is 5.39.

The answer to question two is $4.75. I got this answer by adding the coupon and the money for the snack so I could find out how much money was the admission for both of them which is 9.50. Then I divided it by 2 because there were 2 people. And last I got the answer $4.75!!!!

Symbols of:

\quad\quad\quad\quad\tt{A = A rea}

\quad\quad\quad\quad\tt{ l = length}

\quad\quad\quad\quad\tt{ b \: = breadth}

Given that:

\quad\quad\quad\quad\tt{A = 315 {cm}^(2) }

\quad\quad\quad\quad\tt{l = 21cm}

\quad\quad\quad\quad\tt{b = \: ? }

Formula for breadth (b):

\quad\quad\quad\quad\tt{breadth = (Area)/(length) }

Solution:

\quad\quad\quad\quad\tt{b = \frac{315 {cm}^(2) }{21cm} }

\quad\quad\quad\tt{\:\:b = {15cm}}

So, the breadth (b) is:

Answer:

Breadth = 15 cm

Step-by-step explanation:

Area = length x breadth

315 = 21 x breadth

(315)/(21) = (21)/(21) * breadth                 [ dividing both sides by 21 ]

15 = 1 * breadth\n\nbreadth = 15 \ cm
