Six angles of a heptagon have measures of 80°, 90°, 100°, 145°, 165° and 170°. The smallest of all the exterior angles measures ____.
80°
150°
190°
10°
Answers
Answer: 10°
Step-by-step explanation:
Since an exterior angle and its corresponding interior angle are supplementary, meaning they have a fixed sum, to minimize the exterior angle, we need to maximize the interior angle.
This means we need to consider the 170° interior angle, so the corresponding exterior angle is 10°.

Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining. What is the range of this function? all real numbers such that y ≤ 40 all real numbers such that y ≥ 0 all real numbers such that 0 ≤ y ≤ 40 all real numbers such that 37.75 ≤ y ≤ 40\
What is a function ?A function is an algebraic expression which relates an independent variable with a dependent variable.
It always comes with a defined range and domain.
Draining rate is at 1.5 gallons per minute
That would be y = 1.5x +c
at x = 0 , y = 40
Therefore the equation is y = 1.5x + 40
and from the data
It can be interpreted that as the time increases the water is draining
The range would be all real numbers such that 0 ≤ y ≤ 40.

By working with percentages we will see that the down payment is of $11,010 and the first monthly payment is of $275.25
How to work with percentages?
First, the total cost is $110,100.
And we know that you initially pay the 10% of that, so the amount that you pay initially is:
P = 0.10* $110,100 = $11,010
So the down payment is of $11,010
The rest is financed over 30 years, so the rest is:
$110,100 - $11,010 = $99,090
Dividing by the number of months:
N = ( $99,090)/(30*12) = $275.25
And there is an interest of the 9%, then the amount that you pay on month x is given by:
[tex]P(x) = $275.25*(1.09)^{x-1}[/tex]
Currently (on the first month, so x = 1)

Explanations:
1st image: The longest side of the triangle is equal to the hypotenuse, which is c squared. Because a squared + b squared equals c squared, that would mean 23 squared + 57 squared equals c squared. 23 squared (23 x 23) equals 529, and 57 squared (57 x 57) equals 3,249. 3,249 + 529 = 3,778. This means that c squared equals 3,778. Now, to find c, we can find the square root of 3,778 which would be 61.5 meters rounded. That’s how I got my answer.
2nd image: 13 squared is the hypotenuse, which equals 169 because 13 x 13 is 169. Therefore, 5 squared (which equals 25) + b squared = 169. 169 - 25 = 144, and that means b squared equals 144. The square root of 144 is 12, so 12 cm is the length of the longer leg.
3rd image: x is equal to the hypotenuse, or c squared. Because the Pythagorean Theorem equation is a squared + b squared = c squared, your equation is 10 squared + 8 squared = x squared. That would make the only relevant answer C.

Given f of x is equal to the quantity x plus 6 end quantity divided by the quantity x squared minus 9x plus 18 end quantity, which of the following is true?
A- f(x) is decreasing for all x < 6
B- f(x) is increasing for all x > 6
C- f(x) is decreasing for all x < 3
D- f(x) is increasing for all x < 3
Answers
Answer:
Step-by-step explanation:
The graph of the given f(x) shows you what you need to know. Nothing cancels. Two answers are going to be true: one for x<3 and one for x>6.
From the graph, you can see that for x>6 the graph is decreasing. That makes B incorrect.
You can also see that for x < 6 The bottom parabola shape is decreasing which makes A true.
Finally at least one of C or D has to be true. As you can see, they both are depending on which shape you look at.
The correct answer is B: f(x) is increasing for all x > 6.
To determine the intervals of increase and decrease for the function f(x), we can analyze the critical points and the behavior of the derivative. The derivative of f(x) is given by:
f'(x) = [(x² - 9x + 18)'(x + 6) - (x + 6)'(x² - 9x + 18)] / (x² - 9x + 18)²
Simplifying the derivative and finding the critical points, we get:
f'(x) = (x² - 3x - 18) / (x² - 9x + 18)²
Setting the numerator equal to zero and solving for x, we find the critical points:
x² - 3x - 18 = 0
(x - 6)(x + 3) = 0
x = 6 or x = -3
Analyzing the intervals created by the critical points and using test points, we find that f(x) is increasing for all x > 6. Therefore, the correct answer is B: f(x) is increasing for all x > 6.

[tex]\tan(\beta)[/tex]
Step-by-step explanation:
For many of these identities, it is helpful to convert everything to sine and cosine, see what cancels, and then work to build out to something. If you have options that you're building toward, aim toward one of them.
[tex]{\tan(\theta)}={\dfrac{\sin(\theta)}{\cos(\theta)}[/tex] and [tex]{\sec(\theta)}={\dfrac{1}{\cos(\theta)}[/tex]
Recall the following reciprocal identity:
[tex]\cot(\theta)=\dfrac{1}{\tan(\theta)}=\dfrac{1}{ \left ( \dfrac{\sin(\theta)}{\cos(\theta)} \right )} =\dfrac{\cos(\theta)}{\sin(\theta)}[/tex]
So, the original expression can be written in terms of only sines and cosines:
[tex]\sin(\beta)\tan(\beta)\sec(\beta)\cot(\beta)[/tex]
[tex]\sin(\beta) * \dfrac{\sin(\beta) }{\cos(\beta) } * \dfrac{1 }{\cos(\beta) } * \dfrac{\cos(\beta) } {\sin(\beta) }[/tex]
[tex]\sin(\beta) * \dfrac{\sin(\beta) \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{---}}{\cos(\beta) \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{---}} * \dfrac{1 }{\cos(\beta) } * \dfrac{\cos(\beta) \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{---}} {\sin(\beta) \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{---}}[/tex]
[tex]\sin(\beta) *\dfrac{1 }{\cos(\beta) }[/tex]
[tex]\dfrac{\sin(\beta)}{\cos(\beta) }[/tex]
Working toward one of the answers provided, this is the tangent function.
The one caveat is that the original expression also was undefined for values of beta that caused the sine function to be zero, whereas this simplified function is only undefined for values of beta where the cosine is equal to zero. However, the questions states that we are only considering values for which the original expression is defined, so, excluding those values of beta, the original expression is equivalent to [tex]\tan(\beta)[/tex].

line / is parallel to line m. the slope of line / is 4/9. what is the slope of line m?
Answers
Answer: 4/9
Step-by-step explanation:
Parallel lines have equivalent slopes.
As line 'l' and line 'm' are parallel to each other ,then the slope of line 'm' is also 4/9.
Parallel lines have the same slope. The slope of line segments is identical because they are all similarly inclined with respect to the positive x-axis. If 'l', and 'm' are the slopes of two parallel lines,
then l = m
Slope-intercept notation for lines may be expressed as y=mx+b.
In this notation, b denotes the location of the line's y-axis intercept, and slope(m) indicates the slope of the line.
The slope of 'l'=4/9
The slope of the two parallel lines is the same.
Therefore, the slope of the parallel line "m" = 4/9.

C.) There is no solution
D.) There are an infinite number of solutions
Answers
Answer:
B.) The only solution is (4, - 1/2)
Step-by-step explanation:
To solve this system of equations using the substitution method, we need to use one equation to find an expression for one of the terms or variables that can be substituted for that term or variable in the other equation.
__
expression for xHere, it is convenient to use the second equation to write an expression for x:
x -2 = -4y
x = 2 -4y . . . . add 2 to both sides
substituteUsing this expression for x, we can write the second equation as ...
3x +2y = 11
3(2 -4y) +2y = 11 . . . . . substitute for x
6 -10y = 11 . . . . . . . . eliminate parenthses
solveThis 2-step equation can be solved in the usual way:
-10y = 5 . . . . . . . subtract the constant to isolate the variable term
y = -5/10 = -1/2 . . . . . divide by the coefficient of the variable
x = 2 -4(-1/2) = 2 +2 = 4 . . . . . find the corresponding x-value
The only solution is (x, y) = (4, -1/2).
The only solution is (x, y) = (4, -1/2). so, the correct option is B.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
we have the system of equations;
3x+2y=11
x−2=−4y
By the substitution method;
use the second equation to write an expression for x:
x -2 = -4y
x = 2 -4y
substitute
3x +2y = 11
3(2 -4y) +2y = 11
6 -10y = 11
solve
-10y = 5
y = -5/10 = -1/2
x = 2 -4(-1/2)
x = 2 +2 = 4
