Find the slope between these two points: (3, -10) and (-2, -30). Show all of your work. what the answer
Answer:
4
Step-by-step explanation:
slope equation is y2-y1/x2-x1
insert points: -30-(-10)/-2-3
simplify: -30+10/-5
simplify further: -20/-5
negatives cancel because there cannot be both on top, making it positive: 20/5
divide: 20/5=4
[tex]\huge\text{$m=\boxed{4}$}[/tex]
Hey there! Start with the slope formula, where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the two known points.
[tex]\begin{aligned}m&=\dfrac{y_2-y_1}{x_2-x_1}\\&=\frac{-30-(-10)}{-2-3}\end{aligned}[/tex]
Simplify.
[tex]\begin{array}{c|l}\textbf{Solving}&\textbf{Reason}\\\cline{1-2}\\m=\dfrac{-30+10}{-2-3}&x-(-y)=x+y\\\\m=\dfrac{-20}{-5}&\text{Addition and subtraction}\\\\m=\dfrac{20}{5}&\text{The negatives cancel out}\\\\m=\dfrac{4}{1}&\text{Divide the numerator and denominator by $5$}\\\\m=\boxed{4}&\dfrac{x}{1}=x\end{aligned}[/tex]

g() = 6x^3 – 2x^2 + 3
Find (f - g)(x).
Answer: [tex]-6x^3 + 4x^2 + 4x-8[/tex]
Step-by-step explanation:
[tex](f-g)(x)=f(x)-g(x)\\\\f(x)-g(x)=(2x^2 + 4x-5)-(6x^3 - 2x^2 + 3)\\\\ f(x)-g(x)=-6x^3 + 4x^2 + 4x-8[/tex]

PLEASE HELP: The markup on a bicycle is.45%. The bike sells for $232.00. Find the cost
to the store owner.
Answer:
$160
Step-by-step explanation:
The bicycle costs the owner of the store 100% of its price.
He then adds 45% of that amount to the cost of the bicycle to come up with the selling price. It is this increase of 45% that is called a 45% markup.
100% + 45% = 145%
The bicycle's selling price is 145% of what it cost the store owner.
Let the original cost be x.
145% of x = $232
1.45x = 232
x = 232/1.45
x = 160
Answer: $160
Answer:
$160

Carlos observes a ship from a cliff. The ship is 1.3 km away from the bottom of
the cliff. Given that the height of the cliff is 150m, find the angle of depression of
the ship.
Answer:
49° approx.Step-by-step explanation:
Step one:
given
The distance of the ship from the base= 1.3km
Height of the cliff= 150m= 1.5km
Step two:
Required
angle of depression
Applying SOH CAH TOA
The opposite is to the angle of depression is the height which is 1.5km
The distance of the ship from the foot of the cliff is the adjacent which is 1.3km

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

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.

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.

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
