The intercept reveals that the first loan amount was $1,560.00.
Every month, Michael's debt to his father drops by 290.
What is an intercept?The term "intercept" refers to the x- and y-intercepts of of a given equation. The x-intercept is the point at which a line crosses the x-axis and the y-intercept is the point at which a line crosses the y-axis.acc to our question-
The amount Michael owes is given by :
y = - 290x +18,560
x = number of months ; y = amount owed
Amount owed after 3 months :
Put x = 3 in the equation :
y= - 290(3) +18,560
y = - 870 + 18560
y = 17690
According to the general form of a linear equation :
y = mx + c
Where, m = slope ; c = intercept
The slope = - 290 ; Intercept = 18560
Slope is the change in y per unit change in x ; The slope means that amount owed, y decreases by 290 per month
The intercept shows that the original amount borrowed is 18560.
Hence,The intercept reveals that the first loan amount was $1,560.00.

An exam has four multiple choice problems, each with five possible answers. If you guess on each problem, what is the probability of getting at least one answer correct? Round your answer to the nearest whole percent.
1/2 is the probability of getting at least one answer correct
How to find the probability of getting at least one answer correct?
Given that: the exam has 4 multiple choice with 5 possible answers. This means there are 20 possible choices ( 5×4 = 20).
That means each problem has a probability of 1/20 correct answer. The probability of getting at least one answer means you either get one, two, three or four correct answers. Thus:
P (at least one correct) = P(1) + P(2) + P(3) + P(4)
= 1/20 + 2/20 + 3/20 + 4/20
= (1+2+3+4)/20
= 10/20
= 1/2

What is the value of X?
Answer:
x=28
Step-by-step explanation:
angle b and angle c are the same measure because it is a iso triangle.
you know triangle sum is 180 so 3x+2(x+20)=180. simplify it to 5x=140
divide both sides by 5
x=28
Answer:
x = 28
Step-by-step explanation:
The triangle is isosceles, meaning that the two base angles (x + 20) are congruent. We can then create an equation that states: (x + 20) + (x + 20) + 3x = 180. Simplifying this, we get 5x + 40 = 180. We can then use reverse order of operations to solve it. Subtract 40 from both sides to get 5x = 140. We will then divide both sides by 5 to get x by itself, getting us the equation x = 28.

The partial fraction of the compound fraction [tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] is [tex]\frac{6}{x - 5}[/tex] [tex]-\frac{5}{x - 3}[/tex]
What is a partial fraction?Partial Fractions are the fractions that are formed when a complex rational expression is split into two or more simpler fractions.
When fractions become too cumbersome to solve we split them into simpler units called partial fractions so that mathematical operations can easily be carried out on them.
[tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] can be split into the form, [tex]\frac{A}{x - 3} + \frac{B}{x - 5}[/tex]
where A and B are constants.
so,
[tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] = [tex]\frac{A}{x - 3} + \frac{B}{x - 5}[/tex]
taking the LCM of the denominators of the split fractions, we have
(x-3)(x-5)
multiply A by x -5 and B by x - 3
fraction becomes
[tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] = [tex]\frac{A(x - 5) + B(x - 3)}{(x - 3)(x - 5)}[/tex]
since the denominators of the Left hand side and right hand side are same, we equate the numerators
A(x - 5) + B( x - 3) = x + 7
Using the cover up rule method,
to find A, we substitute x = 3 into the equation so that B becomes zero
A(3 - 5) = 3 + 7
-2A = 10
A = 10/-2
A = -5
To find A put x = 5 so that A = 0
B(5 - 3) = 5 = 7
2B = 12
B = 12/2 = 6
Substituting B and A into the partial fractions above
we have,
[tex]\frac{6}{x - 5}[/tex] [tex]-\frac{5}{x - 3}[/tex]
In conclusion the partial fractions are [tex]\frac{6}{x - 5}[/tex] [tex]-\frac{5}{x - 3}[/tex]

why are 0.8 and 0.80 are equivalent?
0.8 and 0.80 are equivalent representations of the same value, with the latter including a trailing zero for precision or clarity.
In mathematics, the decimal representation of numbers allows for the use of trailing zeros after the decimal point. When a decimal number has trailing zeros, such as in the case of 0.8 and 0.80, they are considered equivalent because they represent the same value.
The trailing zeros after the decimal point do not change the numerical value of the number. The number 0.8 represents eight tenths, and adding a trailing zero to make it 0.80 does not change its value; it still represents eight tenths. The zero after the decimal point in 0.80 is simply a placeholder, indicating that there are no hundredths or smaller fractional parts.
It is common to use trailing zeros in decimal representations to indicate the precision or accuracy of a measurement. For example, if a measurement is known to be accurate to two decimal places, it is common to represent it as 0.80 rather than 0.8 to indicate the level of precision.
Therefore, mathematically speaking, 0.8 and 0.80 are equivalent representations of the same value, with the latter including a trailing zero for precision or clarity.

(a) Find an exponential function of the form f(t)=y0b^t to model these data in which t=0 corresponds to 2004.
The exponential model of the given data is f(t) = 30.18 × 1.06^t.
What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
Given that,
The average price for office space in 2004 is $30.18.
The average price for office space in 2015 is $66.85.
Suppose the average price in 2004 is taken as y₀.
The given situation can be represented in the form of exponential function f(t) = y₀b^t as,
Take t = 0 for 2004
Then, f(0) = y₀b^0
⇒ f(0) = y₀ = $30.18.
Then, at 2015, t = 12. Substitute the respective values to get,
f(12) = 30.18 × b^12
⇒ 66.85 = 30.18 × b^12
⇒ b^12 = 66.85 / 30.18
⇒ b = 1.06
Thus in exponential form the given situation can be written as,
f(t) =30.18 × 1.06^t
Hence, the given data can be modeled in exponential function as f(t) =30.18 × 1.06^t.
