Answer:
Energy cannot be created nor can it be destroyed. Energy may only be transferred or transformed into a different form of energy. An example would be when plants convert light energy into chemical energy in a process called photosynthesis.
Step-by-step explanation:
Answer:
The law of conservation of energy is " Energy can neither be created nor destroyed but transform it from one form to another".
For example:
solar energy to wind energy
electrical energy to heat energy
Write the quadratic equation in standard form.
Answer:
2x² + 6x + 15 = 0
Step-by-step explanation:
Given quadratic equation is,
-2x² - 6x = 15
We have to convert this equation in the standard form of the quadratic equation,
ax² + bx + c = 0
(-2x² - 6x) = 15
-2x² - 6x - 15 = 0
2x² + 6x + 15 = 0

A clothing store conducts a survey to determine customer satisfaction.
Which of these methods will produce the most representative sample of the population of store customers?
A. Survey all customers as they arrive at the store on a Monday.
B. Survey all customers who purchase shoes
C. Survey every 10th customer to enter the store.
D. Survey all customers who leave the store without making a purchase
Answer:
C
Step-by-step explanation:
This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.
Answer:
A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C
C is your answer.

Find the values of x and y in the diagram.
Answer:
x = 2, y = 6
Step-by-step explanation:
Δ WXY is equilateral ( 3 congruent angles ), then the sides are equal
WY = WX , that is
y - 1 = 5 ( add 1 to both sides )
y = 6
Δ WYZ is isosceles ( 2 congruent base angles ) then the legs are congruent
YZ = WY , that is
x + 3 = 5 ( subtract 3 from both sides )
x = 2
Write an exponential function that has a starting value of 0.1 and a decay rate of 0.1%.
Answer:
The answer is Exponential decay, 25% decrease
Step-by-step explanation:
In f(x) = 16(0.75)x the (0.75) does not have a 1 so it is decreasing and if it is only 75% of 16 then it would be losing 25% each time
Does the following graph represent a proportional or non-proportional relationship? Explain your reasoning.
Answer:
Non-proportional relationship
Step-by-step explanation:
Proportional relationships must pass through the origin. Otherwise, at [tex]x=0[/tex], we lose the constant of proportionality, and the y-value at [tex]x=0[/tex] becomes correlated only to the y-intercept.
The format for a proportional relationships is given by [tex]y=kx[/tex], where [tex]k[/tex] is some constant referred to as the constant of proportionality.

Dave and 6 friends went to dinner. They split the bill evenly. The total for the meal was $84. How much did each friend pay
Step-by-step explanation:
Dave + 6 friends = 7 friends in total
84 ÷ 7 = 12
Each friend paid $12
Each of them paid $12 for the Meal.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Dave and 6 friends went to dinner.
Total amount of meal= $84
So, each of them paid
= 84/ 7
= 12
Thus, each of them paid $12.

Prime numbers
Step-by-step explanation:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Answer:
They will meet in 2.25 hours or 2 hours 15 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Let the number of hours at which they meet be x
In x hours, the distance traveled by Karen will be 59 * x = 59x miles
In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles
Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed
However, the sum of whatever they have traveled will be equal to the distance between them
thus;
59x + 65x = 279
124x = 279
x = 279/124
x = 2.25 hours

Which statement describes the sequence defined by a Subscript n Baseline = StartFraction n cubed + 3 n Over n squared minus 6 n EndFraction?
Answer:
Option (1)
Step-by-step explanation:
Sequence has been given as,
[tex]a_n=\frac{n^3+3n}{n^2-6n}[/tex]
[tex]\lim_{n \to \infty}\frac{n^3+3n}{n^2-6n}[/tex]
[tex]=\lim_{n \to \infty}\frac{\frac{n^3+3n}{n^3} }{\frac{n^2-6n}{n^3} }[/tex]
[tex]=\lim_{n \to \infty}\frac{1+\frac{3}{n^2}}{\frac{1}{n}-\frac{6}{n^2} }[/tex]
= ∞
That means with the increase in the value of 'n' sequence gets larger and larger.
Therefore, sequence will diverge.
Option 1 will be the correct option.

SOLVE THIS QUESTION AND GET MARKED BRAINLIEST
Answer:
2/7=0.285714
3/7=0.428571
4/7=0.571428
5/7=0.714285
6/7=0.857142
Step-by-step explanation:
1/7 = 0.142857
2/7=2(1/7)
2/7=2(0.142857)
2/7=0.285714
3/7=1/7+2/7
3/7=0.142857+0.285714
