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

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.

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)
