Answer:

180

Step-by-step explanation:

15% of 300 is 45.

25% of 300 is 75.

45+75 is 120.

300-120 is 180

Answer:

Many solutions

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.

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]

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

Tan ∅=Opp/Adj

Tan ∅=1.5/1.3

∅=Tan-1 1.5/1.3

∅=Tan-1 1.153

∅=49.06

49° approx.

Step-by-step explanation:

2x+3>4x-8

or, 3+8>4x-2x

or, 11>2x

or, 11/2 > x

or, x < 11/2

Number 3 is the answer

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

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:

$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:

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]
