Find the length of each arc. Round your answers to the nearest tenth. NO LINKS!! Part 1
Answers
5) 18.8 cm
7) 49.5 ft
Explanation:
The formula for arc length is S = θ * r
5) S = 18 cm * Pi/3 (60 degrees in radians)
S = 6 Pi cm
S ≈ 18.8 cm
7) S = 9 ft * 7 Pi / 4
S = 63 Pi ft / 4
S ≈ 49.5 ft
Length of arc=r\(\theta\)
So
#1
\(\\ \rm\Rrightarrow Area=18(\pi/3)=6\pi cm\)
#2
\(\\ \rm\Rrightarrow Area=9(7\pi/4)=63\pi /4ft\)

Which sequence of transformations was applied to the parent tangent function to create the function m(x) = 2tan(3x+4)
Answers
The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.
To determine the sequence of transformations, let's break down the given function:
1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.
2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.
3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.
4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.
5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.
In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.
Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.
After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)
This example helps illustrate the effect of the transformations on the graph of the function.

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Base = 5.12
height = 4.11
Lenght = 4
Now, We can formulate;
The value of volume of prism is,
⇒ V = 1/2 (b x h) l
⇒ V = 1/2 (5.12 x 4.11) 4
⇒ V = 42.09 cubic units
Thus, The volume of prism is,

Answer: 2a < 2b
Step-by-step explanation:
We are given a statement:
a < b and b < c, then 2a ____ 2b
We can use simple numbers that make the statement true.
Where,
a = 2
b = 3
c = 4
Now lets plug it in.
2 < 3 and 3 < 4, then 2(2) ____ 2(3)
and lets simplify:
2 < 3 and 3 < 4, then 4 ____ 6
We can see that 4 is less than 6,
so as a is less than b, 2a is less than 2b.

A rentail truck company charges $25 per day plus $0.35 for every mile (m) driven. Which equation can be used to find the number of miles driven for a truck that costs a total of $42.50 to rent for one day?
Answers
Answer:
0.35m + 25 = 42.50
Step-by-step explanation:
If you were to rent a truck for one day you will first have to pay a $25 fee for one day. This is represented by + 25 in the equation above.
Then for every mile you go you must pay $0.35, represented as 0.35m.
As an example to make it easier if you had to pay 1 dollar per mile and you went 10 miles it would cost $10. This can be proved by 1m (m being the variable for number of miles) Plug in 10 for m and you can asee 1(10)=10, because obviously 1 times 10 is 10.
Same premise with $0.35
Then both of those fees added up are equal to a total of $42.50.
To prove it can find the exact number of miles that need to be driven to cost a total of $42.50 just follow steps bellow.
1. 0.35m + 25 - 25 = 42.50 - 25
Subtracting the inital fee since it is part of the total, and if you add/subtract/multiply/divide on one side you must do to the other.
2. 0.35m/0.35 = 17.50/0.35
You divide because m is being multiplied with 0.35 and to undo the multiplication you divide. Doing the same to both sides.
3. m = 50
Plug in 50 to "m" in the equation above and if both sides are equal the answer is valid.

Ahab spent the day at the mall. First, he bought three tires for $50 each. Later, he returned one tire. After that, he found a five dollar bill. Also,he bought two jackets for $40 each. Write the total change to Ahab's funds as an integer.
Answers
Ahab's total change to funds is -$175, which means he spent more than he gained.
What are the funds?Ahab spent 3 tires at $50 each, which is a total of 3 x $50 = $150.
Later, he returned one tire, so he gets $50 back.
He also found a $5 bill, so he has an extra $5.
He then bought 2 jackets at $40 each, which is a total of 2 x $40 = $80.
The total amount Ahab spent is $150 + $80 = $230.
However, he also received $50 back and found $5, so his total change to funds is $50 + $5 - $230 = -$175.
Therefore, Ahab's total change to funds is -$175, which means he spent more than he gained.

If $620 is invested at 6% per

Answers
Answer:
It will take 2 1/2 years
Step-by-step explanation:
Using simple interest, it is found that it will take 2.5 years for the account to reach $713.
The amount of money after t years in simple interest is modeled by:
\(A(t) = A(0)(1 + rt)\)
In which:
A(0) is the initial amount. r is the interest rate, as a decimal.For this problem, the parameters are: \(A(t) = 713, A(0) = 620, r = 0.06\).
Then:
\(A(t) = A(0)(1 + rt)\)
\(713 = 620(1 + 0.06t)\)
\(1 + 0.06t = \frac{713}{620}\)
\(0.06t = 1.15 - 1\)
\(0.06t = 0.15\)
\(t = \frac{0.15}{0.06}\)
\(t = 2.5\)
