Using the slope concept, it is found that the distances from the shore at each moment are given by:
a) 2664 feet.
b) 976 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
Item a:
The vertical distance is of 280 feet, with an angle of 6º. The distance from the shore is the horizontal distance of x. Hence:
[tex]\tan{6^\circ} = \frac{280}{x}[/tex]
[tex]x = \frac{280}{\tan{6^\circ}}[/tex]
x = 2664.
Item b:
The vertical distance is of 280 feet, with an angle of 16º. The distance from the shore is the horizontal distance of x. Hence:
[tex]\tan{16^\circ} = \frac{280}{x}[/tex]
[tex]x = \frac{280}{\tan{16^\circ}}[/tex]
x = 976.

Answer:
see attached
Step-by-step explanation:
You know that f(0) = 2^0 = 1, so g(0) = -11 has been shifted down 12 units from f(x). A shift of half as much will be a shift down 6 units from f(x), or up 6 units from g(x).
In the attached, we have named the new function h(x). It is equivalent to g(x)+6. That is, you can add 6 to each of the g(x) table values to get the corresponding values for h(x).

Find the volume of each shape. Round your answer to two decimal places.with clear explanation.
Answer:
Volume = 111.33 in.³
Step-by-step explanation:
The volume of the shape = volume of the rectangular prism part + volume of the triangular prism part
✔️volume of the rectangular prism part:
V = L*W*H
Where,
L = 5.1 in.
W = 3.4 in.
H = 5.9 in.
V = 5.1*3.4*5.9
V = 102.306 in.³
✔️volume of the triangular prism part:
V = ½*b*h*l
b = 6 - 5.1 = 0.9 in.
h = 5.9 in.
l = 3.4 in.
V = ½*0.9*5.9*3.4
V = 9.027 in.³
✅Volume of the shape = 102.306 + 9.027
= 111.333 in.³
≈ 111.33 in.³ (approximated to 2 decimal places)

Answer:
[tex] \rm \displaystyle {48x}^{3} + 393 {x}^{2} +1014x + 660[/tex]
Step-by-step explanation:
we would like to simplify the following:
[tex] \rm \displaystyle (5x + 24)(9x + 12) + (3x + 9)(8x + 6)(2x + 7)[/tex]
there're two parts the multiplication the whole part to solve the multiplication part we can consider FOIL and for the whole, PEMDAS which can be represented as
[tex] \rm\displaystyle \rm \displaystyle \underbrace{\underbrace{(5x + 24)(9x + 12) } _{ \text{FOIL - 1}}+ \underbrace{ (3x + 9)(8x + 6)(2x + 7)} _{ \text{FOIL - 2}}} _{ \text{PEMDAS}}[/tex]
let's figure out FOIL-1 part
By FOIL we obtain:
[tex] \displaystyle {45x}^{2} + 60x + 216x + 288[/tex]
simplify addition:
[tex] \displaystyle {45x}^{2} + 276x+ 288[/tex]
let's figure out FOIL-2:
By FOIL and PEMDAS we acquire:
[tex] \rm \displaystyle {48x}^{3 } + {348x}^{2} + 738x + 378[/tex]
finally the whole part
[tex] \rm \displaystyle {45x}^{2} + 60x + 216x + 288+ {48x}^{3 } + {348x}^{2} + 738x + 378[/tex]
combine like terms:
[tex] \rm \displaystyle {48x}^{3} + 393 {x}^{2} +1014x + 660[/tex]
and we are done!

Answer:
r=1/2πhA
Step-by-step explanation:
..................
Therefore, the formula of [tex]r[/tex] is [tex]2A(\pi h)^{-1}[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]A=\frac{1}{2}\pi rh[/tex]
So,
[tex]A=\frac{1}{2}\pi rh\\\\r=2A(\frac{1}{\pi h})\\\\r=2A(\pi h)^{-1}[/tex]

The interior angle of a polygon is 100 . The other interior angle are all equal to 110. how many sides has the polygon?
There is a formula for the total interior angles of a polygon:
180(sides−2)=total interior angles
One of the angles is 100 and all the others are 110.
We can rewrite the equation.
Assume there is x number of sides.
There are x−1 number of angles, 110 degrees
180(x−2)=100+110(x−1)
180x−360=100+110x−110
70x−360=100−110
70x−360=−10
70x=3507x=35
x=5
There are 5 sides to the polygon.
We can check our answer:
180(sides−2)=total interior angles
Therefore it is true:
The polygon has 5 sides

Find the area of the figure below
Options
360 ft²
240 ft²
275 ft²
300 ft²
Answer:
The total area is 300 ft^2
Step-by-step explanation:
First find the area of the rectangle
A = l*w = 24*10 = 240
Then find the area of the triangle on the top
A = 1/2 bh
The base is 24 and the height is 15-10 = 5
A = 1/2 (24)*5 = 60
Add them together
240+60 = 300
The total area is 300 ft^2
Answer:
Total area of figure is 300 ft ²
Step-by-step explanation:
Finding the area of rectangle
We know that
Area of rectangle = length × widthWhere,
length of rectangle = 10 ftwidth of rectangle = 24 ftSubstitute the values into the formula
Area = 10 ft × 24 ft
multiply ✖ , we get
Area of rectangle = 240 ft ²
Similarly, Finding the area of triangle
We know
Area of triangle = 1 /2 × Base × HeightWhere,
Base of triangle = 24 ftHeight of triangle = 15 - 10 = 5 ftSubstitute the values
Area of triangle = 1 /2 × 24 ft × 5 ft
multiply
Area of triangle = 1/2 × 120 ft ².
divide , we get
Area of triangle = 60 ft ².
And Finally, Finding the total area
Total area of figure = Area of rectangle + Area of triangle
Total Area = 240 ft ² + 60 ft ²
➛ Total area of figure = 300 ft ²

A basketball player scored 14 times during one game. She scored a total of 15 points, two for each two-point shot and one for each free throw. How many two-point shots did she make? How many free throws?
She made ____ two-point shots
Answer:
The player made one two-point shot and 13 free throws.
Step-by-step explanation:
We can write a system of equations to model the situation.
Let t represent the number of two-point shots and let f represent the number of free throws made.
Since she scored a total of 14 times, the sum of two-pointers and free throws must equal 14. Hence:
[tex]t+f=14[/tex]
And since she scored a total of 15 points and each two-pointers is worth two points and every free throw is worth one:
[tex]2t+f=15[/tex]
Solve the system. We can use elimination. From the first equation, multiply both sides by negative one:
[tex]-t-f=-14[/tex]
We can add this to the second equation:
[tex](2t+f)+(-t-f)=(15)+(-14)[/tex]
Simplify:
[tex]t=1[/tex]
So, the player made only one two-point shot.
Using the first equation again, substitute one for t and solve for f:
[tex](1)+f=14\Rightarrow f=13[/tex]
Therefore, the player made one two-point shot and 13 free throws.
