From the top of a 200 foot lighthouse, the angle of depression to a ship on the ocean is 23 degrees.
How far is the ship from the base of the lighthouse?
I know I did it right by the key says its wrong. Please provide steps
the ship is 472 m from the lighthouse
Step-by-step explanation:
from the question, we can know ∠OAS = 90°-23° =67° and AO = 200m
OS = A0 • tan 67°
= 200 m • 236°
= 472 m
Round 19.432 to the nearest whole.

Step-by-step explanation:
The table below shows the equations of five lines.
line 1: y= 2x - 3
line 2: 2x + y - 3 = 0
line 3: y= 5x + 11
line 4: 2x - y = 10
line 5: y= 1/2x - 5
a) which line has the greatest slope? explain ur answer.
b) which lines are parallel? show workings and explain
c) which lines are perpendicular? show workings and explain.
d) at which point does line 3 cross the y-axis?
Answer:
a) line 3 because the coefficient of the term 5x, the slope is the greatest slope.
b) line 1 and 4 are parallel because they have the same slope: 2
c) line 1 with line 2 and line 4 with line 2 are perpendicular lines because their slopes are reciprocals negative.
d) line three crosses the y line at point 11
Step-by-step explanation:
Line 1. y = 2x - 3
Line 2: y = -2x + 3
Line 3: y = 5x + 11
Line 4: y = 2x - 10
Line 5: y = 1/2x - 5
A balloon is being inflated mechanically in such a way that the volume is increasing at a constant rate of 15 cm3 /s. If the volume of the balloon was originally 30 cm3, determine the average rate of change of the volume of the balloon with respect to the radius of the balloon, to the nearest centimetre cubed per centimetre, between 0 s and 10s, and between 10 s and 20 s.Discuss the following question:Is the rate of change of volume with respect to radius constant?
The magnitude of the volume of the balloon increases at a faster rate than
the radius of the balloon.
The rate of change of the volume of the balloon with respect to radius is not constant.Reasons:
The rate at which the volume of the balloon is increasing, [tex]\dfrac{dV}{dt} = 15 \ cm^3/s[/tex]
The initial volume of the balloon, V = 30 cm³
The rate of change of the volume of the balloon with radius is given as follows;
[tex]\dfrac{\Delta V}{\Delta r}= \dfrac{V_2 - V_1}{r_2 - r_1}[/tex]
[tex]Volume \ of \ the \ balloon, \ V = \dfrac{4}{3} \cdot \pi \cdot r^3[/tex]
[tex]V = 30 + \dfrac{dV}{dt} \times t[/tex]
∴ V = 30 + 15·t
At t = 0, V = 30 cm³
Where;
[tex]r =\sqrt[3]{ \dfrac{3 \cdot V}{4 \cdot \pi} }[/tex]
When V = 30
[tex]r =\sqrt[3]{ \dfrac{3 \times 30}{4 \cdot \pi} } \approx 1.93[/tex]The radius, r ≈ 1.93 cm.
At t = 10 s., we have;
V = 30 + 15 × 10 = 180
[tex]r =\sqrt[3]{ \dfrac{3 \times 180}{4 \cdot \pi} } \approx 3.5[/tex]At t = 20 s., we have;
V = 30 + 15 × 20 = 330
[tex]r =\sqrt[3]{ \dfrac{3 \times 330}{4 \cdot \pi} } \approx 4.29[/tex]Therefore;
Between 0 s. and 10 s., we have;
[tex]\dfrac{\Delta V}{\Delta r}=\dfrac{180 - 30}{3.5-1.93} \approx 96[/tex]Rate of change of the volume of the balloon with respect to the radius of the balloon to the nearest centimeter, between 0 s and 10 s is 96 cm³/cm.
Between 10 s. and 20 s., we have;
[tex]\dfrac{\Delta V}{\Delta r}=\dfrac{330 - 180}{4.29 - 3.5} \approx 190[/tex]Between 10 s. and 20 s. the rate of change is approximately 190 cm³/cm.
Therefore;
The rate of change of the volume of the balloon with respect to radius is not constant, but increases as the volume of the balloon increases.

Answer:
The graph is linear and shaded below the line.
Step-by-step explanation:
It looks like the graph is linear, since the line is straight and continues on forever in both directions. It's not quadratic or absolute value, since quadratic graphs are curved and absolute value graphs branch off in two directions.
If you look at the Desmos graph attached, the shade is below the line, not above the line.
Finally, (0, 0) is not a solution since this point is not part of the shaded section of the graph.

=======================================================
Explanation:
Let x be the unknown positive integer.
The square roots of x are [tex]\sqrt{x}[/tex] and [tex]-\sqrt{x}[/tex], representing the positive and negative square roots respectively.
Taking the difference of those means we subtract:
[tex]\text{PositiveRoot}-\text{NegativeRoot} = \sqrt{x} - (-\sqrt{x}) = \sqrt{x}+\sqrt{x} = 2\sqrt{x}[/tex]
Set that equal to 40 and solve for x
[tex]2\sqrt{x} = 40\\\\\sqrt{x} = 40/2\\\\\sqrt{x} = 20\\\\x = 20^2\\\\x = 400[/tex]
Therefore, the integer we're after is 400.
The positive square root of such is [tex]\sqrt{x} = \sqrt{400} = \sqrt{20^2} = 20[/tex]
And the negative square root is [tex]-\sqrt{x} = -\sqrt{400} = -\sqrt{20^2} = -20[/tex]
The difference of which is:
(Positive Root) - (Negative Root) = 20-(-20) = 20+20 = 40
This helps confirm the answers.
