What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
To determine the time it takes to attach the wheels and hoods on 42 toy cars
According to the given condition, the arithmetic form would be as
⇒ 42 × (8.216 + 3.652)
Calculate the sum of the difference to get,
⇒ 42 × (11.868)
Apply the multiplication operation, and we get
⇒ 498.456
Therefore, it takes 498.456 seconds to attach the wheels and hoods on 42 toy cars.

Write the parametric equations x = 4 \sin^2 \theta , \quad y = 3 \cos^2 \theta in the given cartesian form.
The Cartesian form of equation is,
3x + 4y = 12
We have to given that,
The parametric equations are,
x = 4 sin² θ
y = 3 cos² θ
Now, Change the parametric equations into cartesian form as,
x = 4 sin² θ
sin² θ = x/4 .. (i)
y = 3 cos² θ
cos² θ = y/3 (ii)
Add equation (i) and (ii),
sin² θ + cos² θ = x/4 + y/3
1 = x/4 + y/3
1 = (3x + 4y)/12
12 = 3x + 4y
3x + 4y = 12
Therefore, The Cartesian form of equation is,
3x + 4y = 12

Find the square root of the fraction 64/100
There are 5,280 feet in 1 mile. If Riley ran 26,400 feet, how many miles did she run? [Type your answer as a number.]
Answer:
She ran 5 miles
Step-by-step explanation:
To solve this, we can easily use proportion.
The question state that there are 5,280 feet in a mile, We are ask to find the number of miles Rily run, if she ran 26,400 feet.
Using proportion;
Let x = the number of miles Rily can run
5,280 feet = 1 mile
26,400 feet = x
Cross-multiply
5280x = 26,400
To get the value of x, we will divide both-side of the equation by 5280
5280x/5280 = 26400/5280
(On the left-hand side of the equation, 5280 will cancel-out 5280 leaving us with x and on the right-hand side of the equation 26400 will divide 5280)
x = 26400 / 5280
x=5 mile
Therefore, If Rily ran 26400 feet, then she has ran 5 miles.

What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
As we know, the expression can be defined as the combination of constants and variables with mathematical operators.
To begin, either multiply or divide the value in parentheses (32-4), which equals 5.
Add the number in the parentheses once more: 90/[10+5 (always do the parenthesis first) [10+5]= 15.
Finally, divide 90/15 by 6, always keeping that in mind (PEMDAS)

The _____ ratio is the ratio of the length of one side of a polygon with the length of a corresponding side of a similar polygon.
The scale ratio is the ratio of the length of one side of a polygon with the length of a corresponding side of a similar polygon.
The ratio you're referring to is called the scale factor. The scale factor is the ratio of the length of one side of a polygon to the length of the corresponding side of a similar polygon. Let's denote this scale factor as ( k ).
To calculate the scale factor, you need to choose corresponding sides from the two similar polygons. Once you've chosen a pair of corresponding sides, divide the length of one side by the length of the corresponding side from the other polygon.
Let's say we have two similar polygons, Polygon A and Polygon B, and we want to find the scale factor between them. Let's denote the length of a side of Polygon A as [tex]\( L_A \)[/tex] and the length of the corresponding side of Polygon B as [tex]\( L_B \)[/tex]. Then, the scale factor, ( k ), is given by:
[tex]\[ k = \frac{L_A}{L_B} \][/tex]
This ratio will give you the scale factor between the two polygons.

What is the image of (5,-1) under same translation?
The image of point (5, -1) under the same translation that maps point P to P' is (1, -8). This translation vector is obtained by subtracting the coordinates of P from P'.
To find the image of point (5, -1) under the same translation T that maps point P to P', we can calculate the vector that represents the translation from P to P' and then apply the same translation to point (5, -1).
The translation vector is given by:
Translation vector = P' - P = (-6, -4) - (-2, 3) = (-4, -7)
Now, to find the image of point (5, -1) under the same translation, we simply add this translation vector to (5, -1):
Image of (5, -1) = (5, -1) + (-4, -7) = (5 - 4, -1 - 7) = (1, -8)
So, the image of point (5, -1) under the translation T is (1, -8). Therefore, the correct answer is B. (1, -8).

The function H(t) = −16t2 + 48t + 12 shows the height H(t), in feet, of a cannon ball after t seconds. A second cannon ball moves in the air along a path represented by g(t) = 10 + 15.2t, where g(t) is the height, in feet, of the object from the ground at time t seconds.
Part A: Create a table using integers 0 through 3 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)
Part B: Explain what the solution from Part A means in the context of the problem. (4 points)
We are given a function H(t) that represents the height of a cannon ball after t seconds as:
[tex]H(t)=-16t^2+48t+12[/tex]
and a second cannon ball is represented by the function g(t) as:
[tex]g(t)=10+15.2t[/tex]
PART A:
t 0 1 2 3
H(t) 12 44 44 12
g(t) 15.2 25.2 40.4 55.6
Hence, between t= 2 seconds and t=3 seconds the ball will meet
such that H(t)=g(t)
Since, we know that the Height H(t) decreases from 44 feet to 12 feet between t=2 to t=3 seconds.
and height g(t) increases from 40.4 feet to 55.6 feet between t=2 to t=3 seconds.
Hence, the two cannon balls will definitely meet between t=2 to t=3 seconds.
and the time at which they meet is calculated by solving:
[tex]H(t)=g(t)\\\\i.e.\\\\\\-16t^2+48t+12=10+15.2t\\\\\\i.e.\\\\\\16t^2-32.8t-2=0\\\\\\i.e.\\\\\\t=-0.059\ and\ t=2.109[/tex]
As t can't be negative.
Hence, we get:
t=2.109 seconds
PART B:
The solution from PART A means that the one of the ball first reach the highest point at 44 feet and then returns back to the initial position and hence follows a parabolic path while the second cannon ball reach a greater height with the increase in time and hence in this phenomena the two balls will definitely meet.
Suppose an investment of $10,000 doubles in value every 13 years. How much is the investment worth after 52 years? After 65 years?
A: $80,000; $100,000
B: $160,000; $320,000
C: $520,000; $650,000
Answer:
Step-by-step explanation:
The answer is actually B. $160,000; $320,000
The reason for this is because -
$10,000 is the constant, so let a= 10,000.
The investment doubles every 13 years, so let b=2.
Let x= the number of 13-year periods.
The value of a $10,000 investment doubling every 13 years will be $160,000 after 52 years and $320,000 after 65 years.
Explanation:To calculate the value of an investment that doubles every 13 years, you can determine the number of times the investment will double over a given period. In this case, after 52 years, the investment will have doubled 4 times (since 52 divided by 13 is 4), and after 65 years, it will have doubled 5 times (since 65 divided by 13 is 5).
The formula for the future value of an investment that doubles is: Future Value = Present Value × (2^number of doublings).
After 52 years, the investment's worth would be calculated as follows:
$10,000 × (2^4) = $10,000 × 16 = $160,000
After 65 years, the investment's worth would be:
$10,000 × (2^5) = $10,000 × 32 = $320,000
Therefore, the correct answers are $160,000 after 52 years and $320,000 after 65 years, which corresponds to choice B.
Assembly Line A produces 45 units in the same time that it takes Assembly Line B to produce 37 units. If Line B produces 555 units, how many units does Line A produce during the same time?
Assembly Line A will produce 24975 units during the same time that Line B produces 555 units.
Explanation:Let's assume that the time it takes for Assembly Line A to produce 45 units is equal to the time it takes for Assembly Line B to produce 37 units. This means that the time it takes for Line A to produce 1 unit is equal to the time it takes for Line B to produce 1 unit.
Now, we can set up a proportion to find how many units Line A will produce during the same time that Line B produces 555 units:
45 units / 1 unit = x units / 555 units
Cross-multiplying, we get:
45 * 555 = x units * 1
x units = 24975 units
Therefore, Line A will produce 24975 units during the same time that Line B produces 555 units.
