**Answer 1**

a) she was** travelling** at **73.3335ft/s**

b) Her **speed in ft/s,** if she were going the** speed limit,** is **51.33345ft/**s

In order to determine the **speed** of Jaqueline, we will need to convert her speed in **mph to ft/s**

a) Using the conversion rate:

1mi/hr = 1.46667ft/s

Convert 50 mph to ft/s (50 mph is his average speed limit)

50 mph = x

Divide both expressions:

[tex]\frac{1}{50} =\frac{1.46667}{x}\\1 \times x = 50 \times 1.4667\\x= 73.3335ft/s[/tex]

Hence she was** travelling** at **73.3335ft/s**

b) The given speed limit is 35mi/hr. Convert to ft/s

[tex]\frac{1}{35} =\frac{1.46667}{x}\\1 \times x = 35 \times 1.4667\\x= 51.33345ft/s[/tex]

Hence her **speed in ft/s,** if she were going the** speed limit,** is **51.33345ft/**s

### Answers

**Answer:**

the one on the right

**Step-by-step explanation:**

pick a random x. I chose 3. insert it into the function and you get f(x) = -|3| - 2 which solves to -5. so look at the graphs to see which one passes through the point (3, -5). The one on the right is the only one that does.

The **graph **that represents [tex]f(x) = |x| -2[/tex] is **graph (a)**

The **equation **of the** graph** is represented as:

[tex]f(x) = |x| -2[/tex]

The above **function** is an illustration of an **absolute value function**.

An **absolute value function **is represented as:

[tex]f(x) = a|x - h| + k[/tex]

Where, the **vertex **of the** function** is represented by (h,k).

So, by comparing:

[tex]f(x) = a|x - h| + k[/tex] and [tex]f(x) = |x| -2[/tex]

We have:

[tex](h,k) = (0,-2)[/tex]

This means that, the **function **f(x) has a** vertex** of (0,-2)

Hence, the **graph **that represents [tex]f(x) = |x| -2[/tex] is **graph (a)**

A group wants to visit a water park over the summer. Tickets cost $10 for each child and 15 for each adult

### Answers

If there are 25 people and a profit of $325, we solve the** system of equations **to find that there were **10 children and 15 adults.**

------------------------------------

For our **system**, we say that:

**x** is the number of **children**.**y** is the number of **adults**.

**Total **of 25 people, thus:

[tex]x + y = 25 \rightarrow x = 25 - y[/tex]

Profit of **$325**, thus, considering that each ticket for a child costs $10 and for an adult $15:

[tex]10x + 15y = 325[/tex]

Since [tex]x = 25 - y[/tex]

[tex]10(25 - y) + 15y = 325[/tex]

[tex]5y = 75[/tex]

[tex]y = \frac{75}{5}[/tex]

[tex]y = 15[/tex]

[tex]x = 25 - y = 25 - 15 = 10[/tex]

There were **10 children and 15 adults **in the visit.
