Answer:

Step-by-step explanation:

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:

Here we want to find all the possible combinations that we can make,

First, let's define the selections that we have, and the number of options for each one of these selections. (Remember that each option can be selected only once)

we have 3 flavors and 2 toppings, so let's analyze this case:

First flavor ----- here we have 10 options

Second flavor ---- because we already selected one before, now we have 9 options.

Third flavor ---- because we already selected two before, now we have 8 options.

First topping --- here we have 5 options,

Second topping --- because we already selected one before, here we have 4 options.

Now the total number of possible combinations will be equal to the product between the number of options for each selection:

C = 10*9*8*5*4 = 14,400

Answer:

10 sessions

Step-by-step explanation:

let s be the number of gym session

and let y be the cost

the cost can be represented as

y=ms+c

given data

Green's Gym

c=$50

m=$30

y=30s+50------------1

Breakout Gym

c=$250

m=$10

y=10s+250------------2

equating 1 and 2 we can find s, which is the number of session

30s+50=10s+250

30s-10s=250-50

20s=200

s=200/20

s=10

     therefore the number of session is 10

Step-by-step explanation:

A football team lost 5 yards on each of 3 plays. Explain how you could use a number line to find the team's change in field position after the 3 plays.

Solution:

Number line is a straight line on which numbers are marked and are separated at regular intervals. A number line can be used for both addition and subtraction. Addition is done by counting to the right while subtraction is done by counting to the left.

Given that the football team lost 5 yards in each of their three downs, this is the same as 3(-5) = (-5) + (-5) + (-5)

Hence since it is negative we move to the left. Starting from 0, we move 5 units to the left 3 times, this gives -15

Answer: SEE EXPLANTION!

Step-by-step explanation:

In rolling a die once, you do have a 1/6 chance of getting 6. In rolling a die once (for the second roll), you do have a 1/2 chance of getting an odd number (getting 1, or 3 or 5).

Thank you!

Answer:

1/2.

Step-by-step explanation:

There are 3 odd numbers on the die (1, 3, 5) and 3 even numbers (2, 4, 6). So, the probability would be 3/6 (3 odd out of a total 6 numbers), which simplfies  to 1/2.

Answer:

r = 2.7 cm

Step-by-step explanation:

From the figure attached,

To find the value of 'r' we will apply the sine rule in ΔRST,

sin(m∠R) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(20)° = [tex]\frac{r}{SR}[/tex]

sin(20)° = [tex]\frac{r}{8}[/tex]

r = 8sin(20)°

r = 8(0.34202)

r = 2.736

r ≈ 2.7 cm

Answer:

yes..the slope is rise over run...the slope is -3

Graphs and functions can be used to illustrate real life events.

The table is given as:

[tex]\left[\begin{array}{cccccccccc}Time&0&1&2&3&4&5&6&7&8\\P_1&90.0&76.5&65.0&55.3&47.0\\P_2&39&37&35&33&31\end{array}\right][/tex]

(a) The pattern in each population

Population 1

This population follows a geometric pattern.

The common ratio (r) is calculated by dividing the subsequent values of population 1.

We have:

[tex]r = \frac{P_1(1)}{P_1(0)}[/tex]

This gives

[tex]r = \frac{76.5}{90.0}[/tex]

[tex]r = 0.85[/tex]

Express as percentage

[tex]r = 85\%[/tex]

Next, we calculate the scale factor (k)

[tex]k = 1 - r[/tex]

[tex]k = 1 - 85\%[/tex]

[tex]k = 15\%[/tex]

Hence, the pattern of population 1 is: the population decreases by 15% each year

Population 2

This population follows an arithmetic pattern.

The common difference (d) is calculated by subtracting the subsequent values of population 1.

We have:

[tex]d = P_2(1) - P_2(0)[/tex]

[tex]d = 37 - 39[/tex]

[tex]d = -2[/tex]

-2 indicates that the population reduces, each year by 2000

(b) Complete the table

For population 1, we keep multiplying current population by 85%.

So, we have:

[tex]P_1(5) = 47.0 \times 85\% = 40.0[/tex]

[tex]P_1(6) = 40.0 \times 85\% = 34.0[/tex]

[tex]P_1(7) = 34.0 \times 85\% = 28.9[/tex]

[tex]P_1(8) = 28.9 \times 85\% = 24.6[/tex]

For population 2, we keep adding -2 to the current population

So, we have:

[tex]P_2(5) = 31 -2 = 29[/tex]

[tex]P_2(6) = 29 -2 = 27[/tex]

[tex]P_2(7) = 27 -2 = 25[/tex]

[tex]P_2(8) = 25 -2 = 23[/tex]

So, the complete table is:

[tex]\left[\begin{array}{cccccccccc}Time&0&1&2&3&4&5&6&7&8\\P_1&90.0&76.5&65.0&55.3&47.0&40.0&34.0&28.9&24.6\\P_2&39&37&35&33&31&29&27&25&23\end{array}\right][/tex]

(c) The graph of the two populations

First, we determine the equations of both populations

Population 1

We have:

[tex]P_1(0) = 90.0[/tex]

[tex]r = 0.85[/tex]

The nth term of a geometric sequence is:

[tex]P_1(n) = P_1(0) \times r^n[/tex]

This gives

[tex]P_1(n) = 90.0 \times 0.85^n[/tex]

Population 1

We have:

[tex]P_2(0) = 39[/tex]

[tex]d = -2[/tex]

The nth term of an arithmetic sequence is:

[tex]P_2(n) = P_1(0) + nd[/tex]

This gives

[tex]P_2(n) = 39 -2 \times n[/tex]

[tex]P_2(n) = 39 -2n[/tex]

See attachment for the graphs of:

[tex]P_1(n) = 90.0 \times 0.85^n[/tex] and [tex]P_2(n) = 39 -2n[/tex]

(d) Determine if both populations ever have the same value

From the attached image, the graph of both populations intersect at:

[tex](8.891,21.218)[/tex] and [tex](16.337,6.327)[/tex]

This means that both populations have equal values, twice

Answer:

-17

Step-by-step explanation:

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
