The answer is 7600 because in order to reach negative coordinates you have to travel the length to 0 then down the scale to -1, -2, -3, and so on and vice versa to get to positive coordinates.
In the year 2010, a person bought a new car for $26000. For each consecutive year after that, the value of the car depreciated by 10%. How much would the car be worth in the year 2014, to the nearest hundred dollars?
Answers
Answer:
$17,100
Step-by-step explanation:
Set up an equation where y is the worth of the car and t is the number of years since 2010:
y = 26000(0.9)^t
Plug in 4 as t, since it is asking about 2014:
y = 26000(0.9)^t
y = 26000(0.9)^4
y = 17058.6
Round to the nearest hundred dollars:
17058.6
= 17,100
So, the car will be worth approximately $17,100

Step-by-step explanation:
GOT IT RIGHT ON KHAN and
150,000 divided by 5 so 30,000 then 30,000 divided by 15
Each video gets an average of 1,500,000 views.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Each video gets an average of 1,500,000 views
Video get Views = 3 x 1,500,000
= 4,500,000 Views
Total Views = 90,000,000 Views
Number of months = Total Views/Views per month
Number of months = 90,000,000 / 4,500,000
= 20 Months
Hence, For 20 Months Dagogo need to upload videos to get 90,000,000 views on his channel.

4.) 10
Answers
Answer:
n = 10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
3n - 8 = 32 - n
Step 2: Solve for n
Add n on both sides: 4n - 8 = 32Add 8 on both sides: 4n = 40Divide 4 on both sides: n = 10Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 3(10) - 8 = 32 - 10Multiply: 30 - 8 = 32 - 10Subtract: 22 = 22Here we see that 22 does indeed equal 22.
∴ n = 10 is the solution to the equation.

Here's a graph of a linear function. write the equation that describes that function.
Answers
Answer:
y = 1/4x + 5
Step-by-step explanation:
Here, we want to write the equation of the function
Generally we can have the equation of a straight line as;
y = mx + b
m is slope, b is the y-intercept
From the graph we have the y-intercept as 5
To get the slope, we select any two points and apply the slope formula
Let us have the points;
(8,7) and (4,6)
the slope will be;
m = (y2-y1)/(x2-x1) = (6-7)/(4-8) = 1/4
So the equation of the line is;
y = 1/4x + 5
if 4 is the constant of proportionality is this equation correct? y = 4x + 2
Answers
Answer:
4 is not the constant. 2 is.
Step-by-step explanation:
In the following equation: y = 4x + 2
x and y are variables. x can be any given number, and y would be the resulting answer.
4 is not the constant, because the product it will produce varies on what x will be.
2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.
Between 9 p.m and 6:45 a.m, the water level in a swimming pool decreased by 3/16 in. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?

The probability that event A occurs is 0.4, and the probability that events A and B both occur is 0.25. If the probability that either event A or event B occurs is 0.6, what is the probability that event B will occur
Answers
Answer:
The probability that event B will occur is 0.45
Step-by-step explanation:
Given;
probability that event A occurs, P(A) = 0.4
the probability that events A and B both occur, P(A ∩ B) = 0.25
the probability that either event A or event B occurs, P(A ∪ B) = 0.6
To determine the probability that event B will occur, we use probability addition rule;
P(A) + P(B) = P(A ∩ B) + P(A ∪ B)
0.4 + P(B) = 0.25 + 0.6
0.4 + P(B) = 0.85
P(B) = 0.85 - 0.4
P(B) = 0.45
Therefore, the probability that event B will occur is 0.45
Where is the midline of this function?
Answers
Answer:
the midline is the line:
y = 0.
Step-by-step explanation:
The midline of a function is a horizontal line that divides evenly the graph of the function in two parts.
Particularly, for trigonometric functions, we usually have:
f(x) = A*sin(k*x + p) + M
Where:
A is the amplitude.
x is the variable
k is a constant related to the frequency of the function.
p is a phase shift
M is the midline of the function, which means that the line that divides evenly the graph is y = M.
For our case, we have:
y = f(x) = 3*sin(2*x - π)
Then:
A = 3
k = 2
p = -π
And we do not have a constant term in that equation, this means that:
M = 0
This means that the line that divides evenly the graph is the line y = 0.

Answers
Answer:
The answer is 7.4
Step-by-step explanation: I don’t really know a better way to tell you the explanation than just tell you the answer
The simplified expression is 7 3/5 or 7.6.
To simplify the expression using the order of operations (also known as PEMDAS), follow these steps:
Step 1: Simplify within parentheses (if any).
There are no parentheses in the expression, so we move to the next step.
Step 2: Perform multiplications and divisions from left to right.
First, let's divide 15 by 5:
15 ÷ 5 = 3
Step 3: Perform additions and subtractions from left to right.
Now, let's add 4 3/5 and 3:
4 3/5 + 3
To add the whole numbers, 4 and 3, we get 7.
To add the fractions, we need a common denominator. The common denominator of 5 and 1 is 5. Converting both fractions to have a denominator of 5:
4 3/5 + 3 = 4 3/5 + 15/5
Now, we can add the fractions:
4 3/5 + 15/5 = (4*5 + 3 + 15) / 5
= (20 + 3 + 15) / 5
= 38/5
Step 4: Express the result in mixed number form (if necessary).
38/5 can be expressed as a mixed number by dividing the numerator (38) by the denominator (5). The quotient is the whole number, and the remainder is the numerator of the fraction:
38 ÷ 5 = 7 with a remainder of 3
Therefore, the simplified expression is 7 3/5, which is equivalent to 7.6 as a decimal.

The value of the expression is,

We have to give that,
An expression is,
⇒ X ~ B (5, 0.85)
for, x = 3
Now, simplify the expression for x = 3 as,
X = ⁵C₃ (0.85)³ (1 - 0.85)³⁻¹
X = (5!/3!2!) (0.85)³ (1 - 0.85)²
X = 10 × (0.85)³ (0.15)²
X = 0.138
Hence, The value of the expression is,
X = 0.138
