The three statement true about the the distance of a dog from a post are-
f(0) = 1.5f(60) = 4f(t) < 5What is termed as the function notations?Function notation is a method of representing a function utilizing symbols and signs.The most common function notation is f(x), which is read as "f" of "x." In this case, the letter x enclosed in parentheses, as well as the entire symbol f(x), represent the domain set as well as range set, respectively.For the given graph in the question,
Function f gives the distance of a dog from a post, in feet, as a function of time, t in seconds, since its owner left.
The time is denotes on the x axis and the distance covered by the dog on the y axis.
This can be described using the function as.
f(t) = d
Consider values from graph.
When, t = 0, d = 1.5 feet
Function notation ; f(0) = 1.5 ......statement 1
When t = 60, d = 4 feet
Function notation ; f(60) = 4 ......statement 2
Now, the maximum value is 5.
Thus, f(t) < 5 .....statement 3
Therefore, the three statement are formed.

Royce deposits $1200 into a savings account. After nine year, he made $3472.32.
What is the annual simple interest rate of the loan?
Answers
The interest rate needed to make $3,472.32 from simple interest on a principal of $1,200.00 over 9 years is 21.04% per year.
How to determine simple interest rate?Simple interest is expressed mathematically as;
A = P( 1 + rt )
Where A is accrued amount, P is principal, r is rate and t is the time period.
Given the data in the question;
Principal P = $1200 Accrued amount A = $3472.3Time period t = 9 yearsInterest rate r = ?Plug the given values into the simple interest formula and solve for r
A = P( 1 + rt )
r = (1/t)(A/P - 1)
r = ( 1/9 )( $3472.3/$1200 - 1)
r = ( 1/9 )( 2.8936 - 1)
r = ( 1/9 )( 1.8936)
r = 0.2104
Convert to percentage
r = 0.2104 × 100%
Rate r = 21.04%
Therefore, the interest rate of the loan is 21.04%.

music lessons at $65 each. Determine the amount of Kai's self-employment taxes for
last month, using the tax rate of 15.3%.
Answers
The amount for Kai's self employment taxes for the last month is $407.745 .
In the question ,
it is given that
number of music lessons that Kai taught = 41
per music lesson charge = $65 .
the tax rate for self employment = 15.3%
So, the total amount earned is = (number of classes)*(per class charge)
= 41*65 = $2665
According to the question .
Kai's self employment tax = 15.3% of total amount earned
On substituting the values , we get
Kai's self employment tax = 15.3% of 2665
= 0.153*2665
= 407.745
Therefore , The amount for Kai's self employment taxes for the last month is $407.745 .

should be used in the mixture?
(1) 10
(2) 15
(3) 25
(4) 30
Pls show work
Answers
The pounds of the less expensive tea used in the mixture is 10 pounds.
The correct option is Option(1) 10.
Given:
Price of less expensive tea = $2.00
Price of expensive tea = $5.00
Price of custom-blended tea = $4.25
The total price of 40 pounds of custom blended tea = 40 × $4.25
= $170
Let the pounds of the less expensive tea used in the mixture be x pounds.
So, the pounds of expensive tea = 40-x
Now, the equation is
2x + 5(40 - x) = 170
2x + 200 - 5x = 170
3x = 30
x = 10 pounds
Therefore, there are 10 pounds of less expensive tea.

Why do we use the term factors?
A factor is a number that completely divides another number. In other words, if multiplying two whole numbers results in a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Factors can be found using either division or multiplication.As an illustration, 3 and 6 are factors of 12 because 12 3 = 4 and 12 6 = 2, respectively. 1, 2, 4, and 12 are the other components that make up 12.f(x) = x^4+ kx³ + 2

Answers
If f bisects angle ABC, then mABF and mCBF should be equal to one another. This means we can set up an equation:
x + 10x -1 = 12x +7
Now evaluate for x, and we get
x = -2, x = 4. Plugging in each value to the original equation, we find it cannot be -2 since angles are positive values. This leaves x = 4.
mCBF = 12(4) + 7 = 55.

The linear equation is:
y = -6*x + 59
The slope is -6, and means that each hour the distance decreases by 6 miles.
The y-intercept is 59, and it is the initial distance to the waterfall.
How to get the linear equation?A general linear equation in the slope-intercept form is:
y = a*x + b
Where a is the slope (also called the rate of change) and b is the y-intercept.
We know that if the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁).
Here we can define the variables:
y = distance
x = hours.
Then we have two points (8, 11) and (9, 5).
So the slope is:
a = (5 - 11)/(9 - 8) = -6
This means that the distance to the waterfall decreases by 6 miles each hour.
Then the linear equation is like:
y = -6*x + b
To find the value of b we can use any of the given points, I will use (9, 5), this means that:
5 = -6*9 + b
5 = -54 + b
54 + 5 = b
59 = b
This is the y-intercept, and gives the initial distance to the waterfall.
The equation is:
y = -6*x + 59

If you received $175.84 on $314 invested at a rate of 7%, for how long did you invest the principal?
Answers
The principal amount was invested for 8 Years.
In the given question, it is stated that when $314 was invested as the Principal amount, it got an Interest of $175.84 at an interest rate of 7%. We have to find out the total period of time the principal amount was kept and got interested in in order to complete the interest amount of $175.84.
To calculate the Interest, we know that the formula for Simple Interest is:
=> S.I. = (P*R*T)/100, where P = Principal amount, R = Rate of Interest, and T is the Time period. Now, putting values in the formula we get:
=> S.I. = (P*R*T)/100
=> 175.84 = (314*7*T)/100
=> T = 17584/2198
=> T = 8
Hence, we get Invested Time for 8 years.
