The distance between the starting point and the second obstacle is 13 meters.

And the total length of one lap is equal to the perimeter of the triangle, which measures 30 meters.

We can see that this distance is equal to the hypotenuse of the triangle on the image.

The two legs measure:

5 meters and 12 meters.

Then using the Pythagorean theorem we can write:

d^2 = 5^2 + 12^2

d = √(5^2 + 12^2) = 13

So the distance between the starting point and obstacle 2 is 13 meters.

b) This will be the perimeter of the triangle, it is:

P = 13 m + 12m + 5m = 30m

Answer: -12

Step-by-step explanation:

0.5(x+6) = 1 + 0.25(x-4)

0.5x + 0.5×6 = 1+ 0.25x - 0.25×4

0.5x - 0.25x = 1 - 1 -3

0.25x = -3

x = -12

A. The equation in standard form: x + 0.50y = 150

B. The equation in slope-intercept from: y = -2x + 300.

C. y = 220 sodas

D. x-intercept is (150, 0)

E. y-intercept is (0, 300).

The standard form for an equation is: Ax + By = C, where C is a constant and A and B are integers.

The slope-intercept form is, y = mx + b, here, m = slope or unit rate, and b = y-intercept.

A. x = number of hotdogs

y = number of sodas

Cost of one hotdog = $1.00

Cost of one soda = $0.50

Total cost = $150

To write the equation in standard form, substitute A = 1, B = 0.5, and C = 150 into Ax + By = C:

x + 0.50y = 150

B. Rewrite x + 0.50y = 150 in slope-intercept form:

x + 0.50y - x = -x + 150

0.50y = -x + 150

Divide both sides by 2

y = -2x + 300 [slope-intercept form]

C. Substitute x = 40 into x + 0.50y = 150:

40 + 0.50y = 150

0.5y = 150 - 40

0.5y = 110

y = 220 sodas

D. Substitute y = 0 into x + 0.50y = 150:

x + 0.50(0) = 150

x = 150

The x-intercept is 150, it means when 0 number of soda is sold, 150 hot dogs is sold.

E. Substitute x = 0 into x + 0.50y = 150:

0 + 0.50y = 150

y = 150/0.5

y = 300

The y-intercept is 300, it means when 0 number of hot dog is sold, 150 sodas are sold.

The the coordinates of the other endpoint of a line segment with an endpoint of (-1,8) and a midpoint of (5, 2) is ( 11,-4 ).

A midpoint is simply a point that divides a line segment into two equal halves.

The midpoint formula is expressed as;

M = ( (x₁+x₂)/2, (y₁+y₂)/2

Given the data in the question;

Midpoint (5,2)

Endpoint 1 ( -1,8)

Endpoint 2 ( x₂,y₂)

To determine the coordinate of endpoint 2, plug the given points into the midpoint formula above and solve for x₂ and y₂.

First, we get the x-coordinate.

x = (x₁+x₂)/2

5 = ( -1 + x₂ )/2

( -1 + x₂ ) = 5 × 2

( -1 + x₂ ) = 10

x₂ = 10 + 1

x₂ = 11

Next, we get the y-coordinate

2 = ( 8 +y₂ )/2

8 +y₂ = 2 × 2

8 + y₂ = 4

y₂ = 4 - 8

y₂ = -4

Therefore, the coordinates of the other endpoint is ( 11,-4).

The number obtained by multiplying 5 and square root 164 is 64.

The square root operator in mathematics can be defined as a factor of a number that, when multiplied by itself, gives the original number.

The square root operator in mathematics is denoted by the symbol "√".

The problem 5 (square root of 164) is calculated as follows;

5 ( square root of 164) = 5√164

5√164 = 5(12.8) = 5 x 12.8 = 64

Thus, we can conclude that using the mathematics operator  "√", the number obtained from 5 (square root of 164)  will be greater than 5 but less than 164.

The equation of the linear function represented by the given table in slope intercept form is y = 2x - 2.

The equation of line can be determine using the slope-intercept formula;

y = mx + b

Where m is slope and b is the y-intercept.

From the given table, we use to points;

Point 1( -1, -4 )

Point 2( 1, 0 )

First, we find the slope of the line.

Slope m = (y₂ - y₁) / (x₂ - x₁ )

Slope m = ( 0 - (-4) ) / (1 - (-1) )

Slope m = ( 0 + 4) ) / (1 + 1) )

Slope m = 4 / 2

Slope m = 2

Next, we find the y-intercept b, using a slope m = 2 and a point ( -1, -4 ).

y = mx + b

-4 = 2(-1) + b

-4 = -2 + b

b = -4 + 2

y-intercept b = -2

Now that we have the slope m and y-intercept b, plug the values into to y = mx + b to determine the equation of line.

y = mx + b

y = 2x + (-2)

y = 2x - 2

Therefore, the equation of the linear function is y = 2x - 2.

Step-by-step explanation:

1) At x = -2, 0, and 5, the solutions are; f(-2) = -2, f(0) = 1 and f(5) = 8.5

2) At x = -2, 0, and 5, the solutions are; g(-2) = 18, g(0) = 13, g(5) = -2

3) At x = -2, 0, and 5, the solutions are; h(-2) = -3, h(0) = -5 and h(5) = -10

We want to evaluate each of the given functions when  x = -2, 0, and 5.

1) f(x) = 1.5x + 1

At x = -2, we plug in -2 for x in the linear equation to get;

f(-2) = 1.5(-2) + 1

f(-2) = -2

At x = 0, we plug in 0 for x in the linear equation to get;

f(0) = 1.5(0) + 1

f(0) = 1

At x = 5, we plug in 5 for x in the linear equation to get;

f(5) = 1.5(5) + 1

f(5) = 8.5

2) g(x) = 11 - 3x + 2 = 13 - 3x

At x = -2, we plug in -2 for x in the linear equation to get;

g(-2) = 13 - 3(-2)

g(-2) = 18

At x = 0, we plug in 0 for x in the linear equation to get;

g(0) = 13 - 3(0)

g(0) = 13

At x = 5, we plug in 5 for x in the linear equation to get;

g(5) = 13 - 3(5)

g(5) = -2

3) h(x) = -3 - x - 2 = -5 - x

At x = -2, we plug in -2 for x in the linear equation to get;

h(-2) =  -5 - (-2)

h(-2) = -3

At x = 0, we plug in 0 for x in the linear equation to get;

h(0) =  -5 - 0

h(0) = -5

At x = 5, we plug in 5 for x in the linear equation to get;

h(5) =  -5 - 5

h(5) = -10

A. In the given question, we know that the Club washed cars and vans. They charge $5 for cars and $7 for vans. They earned a total of $243. Also, they washed a total of 45 vehicles. We have to find out the Equations for the Linear system

Let, the Number of Cars = 'c', and the Number of Vans = 'v', then the equation representing the total number of vehicles will be:

=> v + c = 45          => Equation (1)

Now, if the cost of washing 1 car is $5 and the van is $7 then,

Cost of washing 'c' car: 5c

Cost of washing 'v' van: 7v

then the equation representing total Earning will be:

=> 7v + 5c = 243          => Equation (2)

B. Now, we have to calculate the system of Linear equations to find out the number of cars and vans.

by equation (1) we get:

=> v + c = 45

=> v = 45 - c               => Equation (3)

Putting this value in Equation(2) we get:

=> 7(45-c) + 5c = 243

=> 315 - 7c + 5c = 243

=> 2c = 72

=> c = 36

Put this value of c = 36 in Equation (3), and we get:

=> v = 45 - 36

=> v = 9

Hence, the system of equations is v + c = 45, and 7v + 5c = 243 and the number of Cars washed is 36 and vans is 9
