The height of a tree, h, depends on its age, a. The ______________________________ is a function of ____________________. The function notation is __ ( __ ).
Answer:
The height of a tree, h, depends on its age, a. The _____________height_________________ is a function of ________age____________. The function notation is _h_ f( _a_ ).
h = f(a)
Step-by-step explanation:
Function notation is the way of representing a language expression in a mathematical form. It reduces the information to a precise way form, thereby avoiding some lengthy written explanations. A mathematical function makes a long explanation to become a simple and short expression. In this example, the height of a tree is expressed as a function of its age, with a simple function, h = f(a), where 'h' = height of the tree and 'a' = age and 'f' = function.

Step-by-step explanation:
How do you solve the slope and y-intercept of a graph?
Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Answer: you can solve the y-intercept by seeing where the line on a graph passes the y-axis line, so if the line touches the 3 on a y axis thats the y-intercept

There are 3 islands A,B,C. Island B is east of island A, 8 miles away. Island C is northeast of A, 5 miles away and northwest of B, 7 miles away. What is the bearing needed to navigate from island B to C? Round to the nearest degree
Answer:
The bearing needed to navigate from island B to island C is approximately 38.213º.
Step-by-step explanation:
The geometrical diagram representing the statement is introduced below as attachment, and from Trigonometry we determine that bearing needed to navigate from island B to C by the Cosine Law:
[tex]AC^{2} = AB^{2}+BC^{2}-2\cdot AB\cdot BC\cdot \cos \theta[/tex] (1)
Where:
[tex]AC[/tex] - The distance from A to C, measured in miles.
[tex]AB[/tex] - The distance from A to B, measured in miles.
[tex]BC[/tex] - The distance from B to C, measured in miles.
[tex]\theta[/tex] - Bearing from island B to island C, measured in sexagesimal degrees.
Then, we clear the bearing angle within the equation:
[tex]AC^{2}-AB^{2}-BC^{2}=-2\cdot AB\cdot BC\cdot \cos \theta[/tex]
[tex]\cos \theta = \frac{BC^{2}+AB^{2}-AC^{2}}{2\cdot AB\cdot BC}[/tex]
[tex]\theta = \cos^{-1}\left(\frac{BC^{2}+AB^{2}-AC^{2}}{2\cdot AB\cdot BC} \right)[/tex] (2)
If we know that [tex]BC = 7\,mi[/tex], [tex]AB = 8\,mi[/tex], [tex]AC = 5\,mi[/tex], then the bearing from island B to island C:
[tex]\theta = \cos^{-1}\left[\frac{(7\mi)^{2}+(8\,mi)^{2}-(5\,mi)^{2}}{2\cdot (8\,mi)\cdot (7\,mi)} \right][/tex]
[tex]\theta \approx 38.213^{\circ}[/tex]
The bearing needed to navigate from island B to island C is approximately 38.213º.

Answer:
The rise is 5
The run is 6
The rate is 5/6
Step-by-step explanation:
Rise is the change in y, or how many units up the line goes. On this graph, y goes up 5. The run is the change in x, or how many units right the line goes; on this graph, it goes 6 units right in between the points. The rate, or slope, is rise over run, so the final answer is 5/6.

Cost of boots: $99.99
Markup: 9%
What is the new cost?
Answer:
New cost of Boots is $108.98
Step-by-step explanation:
Original Cost of boots : $99.99
Markup = 9%
New Cost of boots = ?
We will find 9% of $99.99 and add the answer in $99.99 to find new cost of boots.
Finding 9% of $99.99
[tex]=\frac{9}{100} \times 99.99\\= 8.99[/tex]
New cost will be:
New cost of Boots= Original Cost of boots + Markup
New cost of Boots= 99.99 + 8.99
New cost of Boots= $108.98
So, New cost of Boots is $108.98

Using the triangle find x and y
Classify the triangle by angles and sides
The perimeter of the triangle is 25 units
Answer:
see explanation
Step-by-step explanation:
Since the base angle are congruent, both 44° then the triangle is isosceles.
Then the 2 legs are congruent, that is
4x - 7 = 2x + 1 ( subtract 2x from both sides )
2x - 7 = 1 ( add 7 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus legs are both 4x - 7 = 4(4) - 7 = 16 - 7 = 9 and base = x + 3 = 4 + 3 = 7
As a check 9 + 9 + 7 = 25 → correct
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180 for y, that is
y = 180 - (44 + 44) = 180 - 88 = 92
Finally
x = 4
y = 92
angles are 92°, 44° and 44°
sides are 9, 9 and 7
