Answers
hope this helps
have a good day
Answer:
67/18 is 3.72 as a decimal.
Step-by-step explanation:
I know this because, to turn a fraction into a decimal, you must divide the numerator by the denominator.
67 ÷ 18 = 3.72
Therefore, 3.72 is my answer.

You buy a used car for $20,000. It depreciates at the rate of 21% per year. Find the value of the car for the given years.
A. 5 years.
B. 8 years.
Answers
Answer:
a is 840 ,b is 525
Step-by-step explanation:
At the end of each year, its value is down to 79%, which is 0.79 times its value at the start of the year. Keep this up for n years and the value is
V(n) = $20,000 (0.79)n,
where n is the number of years elapsed from when the value was $20,000. Just plug in n=5 and n=8, evaluate, and get your 2 answers.
Answer:
A. 5 years
Step-by-step explanation:
21% of 20,000 is 4200, mutiply that by 5 and get $20,000

i dont get what you are trying to say is their a graph u can show
Step-by-step explanation:
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (3, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 2x - 1 ← equation of line

Step-by-step explanation:
(a+b)^3
= (a+b) (a+b) (a+b)
={(a+b) (a+b)} (a+b)
={a(a+b) + b(a+b)} (a+b)
=(a^2 + ab + ab + b^2) (a+b)
=(a^2 + b^2 + 2ab) (a+b)
=a^2(a+b) + b^2(a+b) + 2ab(a+b)
=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2
=a^3 + b^3 + 3a^2b + 3ab^2
=a^3 + b^3 + 3ab(a+b)
(a+b)^3 = a^3 + b^3 + 3ab(a+b)
(a+b)^3 - 3ab(a+b) = a^3 + b^3
a^3 + b^3 = (a+b)^3 - 3ab(a+b)

weight = 5, 6.5, 7.2, 9, 16
cost = $2.50, $3.25, $3.60, $4.50, $8.00
Step-by-step explanation:
The first column tells you the cost is ...
$2.50/(5 lb) = 0.50 $/lb
That is, each bottom number is half the top number, or each top number is double the bottom number.
The table is ...
weight = 5, 6.5, 7.2, 9, 16

Elijah is keeping track of his baby sister’s shoe size at different ages throughout her childhood. Which statements about the relationship between Elijah’s sister’s shoe size and her age are true? Select all that apply.
A. The relationship is a continuous function.
B. The relationship is a discrete function.
C. The domain and range are restricted to positive numbers.
D. The domain and range are restricted to positive integers.
Answers
Answer:
B and D
Step-by-step explanation:
The function is the relation between the sister's shoe size and her age, being age the independent variable x, and the shoe size the dependent variable y.
If we think this through, we'll find out that age is a discrete variable, and shoe size too. Discrete variable refers to those variable that only admit whole numbers, they don't admit decimal numbers. So, in this case, both variables aren't represented by decimal values. So, the relationship is discrete function, punctual data.
Similarly, the function must be restricted to positive integers, because, as we already said, the variable only admit discrete values and we have to add that only should admit positive discrete values, because age cannot be negative, it wouldn't make sense, also shoe size cannot be negative. In this context, negative numbers don't make any sense.

1.72r²
Step-by-step explanation:
total Rectangle area = 4r*2r = 8r²
total circles area = 2(π r²) = 2*3.14*r² = 6.28r²
then:
the area of the shaded region:
= 8r² - 6.28r²
= (8-6.28)r²
= 1.72r²
Answer:
2r²(4 - π)
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of rectangle - area of 2 circles
The rectangle has a length of 4r and a width of 2r , then
A = (4r × 2r) - (2πr²)
= 8r² - 2πr² ← factor out 2r² from each term
= 2r²(4 - π)

What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The graph of the logarithmic function y=logx is shown.
The domain of function f(x) = logx is the set of all positive real numbers.
1. f(x)=logx domain of the logirthimic function is (0, ∞).
2. The range is the set of all real numbers.
3. The function is continuous and one-to-one.
4. The y-axis is the asymptote of the graph.
5. The graph intersects the x-axis at (1,0). That is, the x-intercept is 1.
Value of function f(x) = logx at axis (1,0)
⇒ f(x) = 0
Thus, value of function f(x) = logx at axis (1,0) is zero.

An airplane flies across the country. Its distance from Portland, as a function of time, is modeled by y. 500x.
Which statement best describes the function?
A. The function is nonlinear
B. The function is linear at some points and nonlinear at other points.
c. The function is linear
D. Not enough information is given to decide
Answers
Answer:
I would say b
Step-by-step explanation:
I choose b because the question is linear and also non linear it only told us the distance which is 500x and no time but is saying as a function of time
C. The function is linear.
The given function is y = 500x, where x represents the time and y represents the distance from Portland. In this function, y is directly proportional to x, meaning that for every unit increase in x, y increases by a constant amount of 500.
Since the function is of the form y = mx, where m (in this case, 500) is the constant of proportionality, the function is linear.
Therefore, the correct answer is:
C. The function is linear.

What is the value of tan A?
8/17
15/8
8/15
15/17
Answers
Answer:
B) 15/8
Step-by-step explanation:
Use the SOH-CAH-TOA acronym:
• SOH: Sin(θ) = Opposite / Hypotenuse
• CAH: Cos(θ) = Adjacent / Hypotenuse
• TOA: Tan(θ) = Opposite / Adjacent
Tangent of A would be "opposite" over "adjacent". The side of the triangle opposite angle A would be 15, and the side adjacent to angle A would be 8 -- the value of tan(A) is 15/8.
Tan(A) cannot be 15/7, because 7 is the hypotenuse. Remember that the hypotenuse of a right triangle is the side opposite the 90° angle -- here, angle B is the 90° angle.
