Sylvia: 35.50 + 6*16 = 131.50

Raul: 15.50 + 6*20 = 135.50

135.50 - 131.50 = 4

Flat fee is a one time cost. The hourly rate you have to multiply by the number of hours (6 in this case), and then add them.

Answer:

B) The distance between communities B and c is 4.95 km.

Step-by-step explanation:

A) Join communities B and C. Then bisect angles A, B and C to determine the mid point equidistant to the three communities. The point where the three bisectors meet, w, is the exact place to dig the well.

The sketch is in the attachment to this answer.

B) Since we have two sides and an included angle, the cosine rule is applicable to determine a (distance between B and C).

[tex]a^{2}[/tex] = [tex]b^{2}[/tex] + [tex]c^{2}[/tex] - 2bc Cos A

b = 7 km, c = 5 km and A = [tex]45^{o}[/tex]. So that;

[tex]a^{2}[/tex] = [tex]7^{2}[/tex] + [tex]5^{2}[/tex] - 2(5 x 7) Cos [tex]45^{o}[/tex]

   = 49 + 25 - 70 x 0.7071

  = 74 - 49.497

  = 24.503

⇒ a = [tex]\sqrt{24.503}[/tex]

      = 4.95

The distance between communities B and c is 4.95 km.

Answer:

The absolute value of any positive number is the number itself, so 11 has 11 as an absolute value. Also, the absolute value of a negative number is its (positive) opposite, so also has 11 as an absolute value.

El valor absoluto de cualquier número positivo es el número en sí, por lo que 11 tiene 11 como valor absoluto. Además, el valor absoluto de un número negativo es su opuesto (positivo), por lo que también tiene 11 como valor absoluto.

"Keith has $500 in a savings account at the beginning of summer he wants to atleast have $200 at the end of summer he withdraws $25 per week for food clothing and movie tickets how many weeks can keth with draw from his account"

given data

amount at hand=$500

amount expected= $200

weekly deduction from amount at hand=$25

Note: this is a reduction situation at a rate of $25

the expression for the situation is given as

y=c-mx

where y=200

c=500

m=25

substituting we have

200=500-25x

solving for x we have

200-500=-25x

-300=-25x

divide both sides by 25 we have

x=300/25

x=12 weeks

A and B

Answer:

A) the diving board is 1m high.

B) maximum height of the diver is 3.25 meter(s)

C)i)the diver is a ascending from 0 metres to 0.5 metres.

II) the diver descends from 0.5 metres to 1 m

Step-by-step explanation:

A) We are given the function;

f(x) = −9x² + 9x + 1

Now, the height of the diving board will be when x = 0 metres. This is because at x = 0, the driver didn't jump.

Thus;

f(0) = -9(0²) + 9(0) + 1

f(0) = 1 m

Thus, the diving board is 1m high.

B) From quadratic equations, we can say that in the given function, we have as follows;

a = -9

b = 9

c = 1

Now, a < 0

This means that the parabola opens down and it's vertex formula will be used and value of x plugged into the given function to get the maximum height.

Thus, vertex is;

x = -b/2a

x = -9/(2 × -9)

x = 1/2

x = 0.5 m

Thus;

Max height = -9(0.5²) + 9(0.5) + 1

Max height = 3.25 m

The maximum height of the diver is 3.25 meter(s)

C) Since the parabola opens down, the diver is ascending from 0 metres to 0.5 metres.

Similarly, the diver descends from 0.5 metres to 1 m

The path of the diver is an illustration of a quadratic function.

The function is given as:

[tex]\mathbf{f(x) = -9x^2 + 9x + 1}[/tex]

(a) The height of the diving board.

This is represented by the constant term in the function.

So, we have:

[tex]\mathbf{Height = 1}[/tex]

Hence, the height of the diving board is 1 meter

(b) The maximum height of the diver

We have:

[tex]\mathbf{f(x) = -9x^2 + 9x + 1}[/tex]

Differentiate

[tex]\mathbf{f'(x) = -18x + 9}[/tex]

Set to 0

[tex]\mathbf{-18x + 9 = 0}[/tex]

Collect like terms

[tex]\mathbf{18x = 9}[/tex]

Divide through by 18

[tex]\mathbf{x = 0.5}[/tex]

Calculate f(0.5)

[tex]\mathbf{f(x) = -9x^2 + 9x + 1}[/tex]

[tex]\mathbf{f(0.5) = -9(0.5)^2 + 9(0.5) +1}[/tex]

[tex]\mathbf{f(0.5) = 3.25}[/tex]

Hence, the maximum height of the diver is 3.25 m

(c) The depth, the diver ascends to

In (b), we have:

[tex]\mathbf{x = 0.5}[/tex]

This means that, the diver ascends from 0 meters to 0.5 meters
