Write an equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1).
An equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1) is 0 = (-2/7)0 + 0
What is a parallel line?Two or more lines that never intersect are said to be parallel. We can see parallel lines all around us, such as in the bookcase's shelves and the two sides of this page.
There is a good chance that lines or structures that appear to run in the same direction, never cross one another, and always have the same spacing between them are parallel.
We will find the slope using the slope formula that is
⇒ m = (y₂ - y₁)/(x₂ - x₁)
Given points are (-5, 3) and (2, 1), so
⇒ m = (1 - 3)/(2 - (-5))
⇒ m = -2/7
We have asked to write an equation for a parallel line that passes through (-5, 3) and (2, 1).
for a two lines to be parallel, m = m for both lines
so as the slope is (-2/7), lets put the value in (0,0)
y = mx + b
0 = (-2/7)0 + b
b = 0
And therefore the equation is 0 = (-2/7)0 + 0

We have to find the value of [tex]10^5*\frac{10^4}{10^2}[/tex]
It is a question of exponents and powers.
Exponents (Power)
Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself. It is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.
For example, the mass of Earth is 5,97,219,00,00,00,00,00,00,00,00,000 kg. This cannot be read in simple words. Thus, to pronounce these types of numbers we make use of exponents.
Hence, the weight of earth will be written as [tex]5.97219 * 10^{24}[/tex].
We know that:-
[tex]x^a*x^b = x^{a+b}[/tex] and,
[tex]x^a/x^b = x^{a-b}[/tex]
Hence, we can write,
[tex]\frac{10^4}{10^2} = 10^{4-2} = 10^2[/tex]

The domain and range of the function f ( x ) is {x all real numbers}; {yl y >0}
What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 2( ∛108 )²ˣ
The domain of the function is all real numbers because there are no restrictions on the variable x.
To find the range, we can simplify the function as follows:
f(x) = 2(∛108)²ˣ
f(x) = 2(6)²ˣ
f(x) = 2(36)ˣ
f(x) = 72ˣ
Since 72ˣ is always positive, the range of the function is {y: y > 0}.
Hence , the domain and range is solved and = {x ∈ R : x ∈ R }, {y ∈ R: y > 0}

jack strong has $50,000 of wealth. he is participating in a jujitsu competition. the prize is $10,000. he is guaranteed to win it (he has black belt) unless he breaks his arm. if his arm is broken, he will lose the tournament and he will have to pay $5,000 in medical expenses. jack thinks that the probability of him breaking his arm during a tournament is 5 percent. he can get a medical insurance at a price of $.3 dollars for each $1 of coverage.
He’ll get the prize of dollar 10000, then the consumption after adding dollar 1500 is: $10000 + $1500 = $11500
a) the derive equation is 50000 + 10000 + x
jack has maximum amount of wealth = $50,000
When he participated in a jujitsu competition then the prize amount = 10,000
Then we will take a variable x for derive the equation which will depend on that he will win and loose :
Here,
the equation is = 50000 + 10000 + x
b) His consumption after not purchasing medical insurance is $15000.
if, he does not purchase medical insurance then he has no coverage of insurance and
He’ll lose the tournament and he’ll have to pay medical expenses dollar 5000 and also the prize amount $10000
So, his consumption after not purchasing medical insurance is:
$10000 + $5000 = $15000
c) when he will purchase medical insurance then his total consumption is $3500
his consumption if he purchase medical insurance, he will give dollar1 for medical insurance and will get in return dollar .3 ,
When he will have to pay for medical insurance $5000, then he’ll get the coverage on medical insurance:
0.3 * 5000 = $1500
Now, subtracting the amount of medical insurance which he’ll have to pay:
$5000 - $1500 = $3500
He’ll get the prize of dollar 10000, then the consumption after adding dollar 1500 is:
$10000 + $1500 = $11500

A factory's production is modeled by function f(x), where f(x) is the number of parts produced per hour and x is
the number of people working during production. Choose the ordered pair that represents a possible domain and
range of the function.
O (-1,15)
O (5, -50)
O (-10, -100)
O (5, 10)
Answer: (5,10)
Step-by-step explanation: We are given that a factory's production is modeled by function f(x).
Where f(x)=Number of parts produced per hour
x=Number of people working during production
We have to choose an ordered pair that represents a possible domain and range of the function.
x is the number of people working during production. It is always positive because time can not be negative.
f(x) is the number of parts produced per hour .It is always positive because quantity of any number cannot be negative. It is always positive.
In first option (-1,15)
x=-1,f(x)=15
x is negative which is not possible.
So, it is false.
In option b(5,-50)
x=5,f(x)=-50
Range is negative which is not possible.
So , it is false.
In option C( -10,-100)
x=-10, f(x)=-100
x and f(x) are both negative therefore, it is false.
In option D (5,10)
x=5 , f(x)=10
x and f(x) are both positive.
So, it is possible ordered pair.
Hence, ordered pair (5,10) in which 5 represent a possible domain and 10 represent the possible range.

Answer:
308 Calories are provided by the Powerbar.
Step-by-step explanation:
Use the typical amounts shown for each nutrient first to calculate how many calories each one provides:
Fat: 4 grams x 9 kcal/gram = 36 kcals.
Protein: 23 grams x 4 kcal/gram = 92 kcals.
45 grams x 4 kcal/gram of carbohydrates equals 180 kcal.
To determine the total calories, add up all the Calories from each nutrient as follows:
92 calories from protein and 36 calories from fat equal 308 calories.
The Powerbar contains 308 calories.
Answer:
Total Calories = (4*9) + (23*4) + (45*4)
36+92+180 = 308 Calories
To calculate total calories we first need to convert total fat, protein, and carbohydrates into calories
1 gram of protein = 4 calories
1 gram of fat = 9 calories
1 gram of carbohydrates = 4 calories
