From the observation deck of a skyscraper, Meena measures a 48∘ angle of depression to a ship in the harbor below. If the observation deck is 1068 feet high, what is the horizontal distance from the base of the skyscraper out to the ship? Round your answer to the nearest tenth of a foot if necessary.
Using the slope concept, it is found that the horizontal distance from the base of the skyscraper out to the ship is of 961.6 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.
In this problem:
The angle is of 48º.The vertical change is of 1068 ft.The horizontal change is of x.Hence:
[tex]\tan{48^\circ} = \frac{1068}{x}[/tex]
[tex]x = \frac{1068}{\tan{48^\circ}}[/tex]
x = 961.6
The horizontal distance from the base of the skyscraper out to the ship is of 961.6 feet.

2. You are making wooden picture
frames of different sizes but you
have limited supplies, so you are
restricting the perimeter of each
frame to 4 feet or less and the length
to exactly 1.5 feet. Find the range of
the frame width. Show your work.
The range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.
What is the range of a particular data set?For a set of data, the range is the difference between the maximum and minimum value. It sort of gives an idea of spread of the data.
For this case, we're given that:
Frame is rectangular (assumingly).The perimeter of the frame ≤ 4 feetThe length of the frame = 1.5 feetPerimeter of a rectangle = 2(length + width)
Let 'l' denotes length, and 'w' denotes width, then we get:
[tex]Perimeter \leq 4\\2(l+w) \leq 4\\2(1.5 + w) \leq 4\\\\\text{Dividing both the sides by 2}\\\\1.5 + w \leq 2\\\\\text{Subtracting 1.5 from both the sides so as to get 'w' on one side}\\\\w \leq 0.5[/tex]
Now since the lowest value of width of a frame can be zero only, therefore, we get:
[tex]0 \leq w \leq 0.5[/tex]
Thus, the range of values 'w' can assume is: 0.5 - 0 = 0.5
Thus, the range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

A carnival has a duck-pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 56 ducks floating in the pond. There are 5 ducks marked as large-prize winners, 10 ducks marked as medium-prize winners, and 20 ducks marked as small-prize winners. Find the theoretical probability of winning a small prize at the duck pond. Express your answer as a percent. If necessary, round your answer to the nearest thousandth.
35.714%

The probability helps us to know the chances of an event occurring. The probability of winning a small prize in the carnival is 35.714%.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that there is a total of 56 ducks floating in the pond, out of which 20 ducks are marked as small-prize winners. Therefore, the probability of winning a small price can be written as:
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\\rm Probability=\dfrac{\text{Nnmber of small price ducks}}{\text{Total number of ducks}}\\\\\\Probability = \dfrac{20}{56} = 0.35714 = 35.714\%[/tex]

2(6-2[3/4]) - 2[3/4] = 2(5+[3/4]) -4
Hope this helps!
Answer:
x = 3/4Therefore , option A is correct .Step-by-step explanation:
In the question we're given with an equation i.e.,
2 ( 6 - 2x ) - 2x = 2 ( 5 + x ) - 4And we are asked to find the value of x .
Solution :
[tex] \longmapsto \: 2 ( 6 - 2x ) - 2x = 2 ( 5 + x ) - 4 [/tex]
Step 1 : Solving parenthesis by multiplying it with 2 on both the sides :
[tex] \longmapsto \: 12 - \bold{4x} - \bold{2x} = \bold{10} + 2x - \bold{4}[/tex]
Step 2 : Adding like terms on left hand side and subtracting like terms on right hand side :
[tex] \longmapsto \: 12 - 6x = 2x + 6[/tex]
Step 3 : Transposing 12 to right hand side and 2x to left hand side :
[tex] \longmapsto \: -2x - 6x = 6 - 12[/tex]
On further calculations we get :
[tex] \longmapsto \: \cancel{ - }8x = \cancel{- }6[/tex]
Step 4 : Transposing 8 to right hand side :
[tex] \longmapsto \: x = \frac{\cancel{6}}{\cancel{8}} [/tex]
Step 5 : Cancelling 6/8 to their simplest form :
[tex] \longmapsto \: \pink{\boxed{x = \frac{3}{4} }}[/tex]
Therefore , value of x is 3/4 and it will make the equation true .#Keep LearningPoint A is an element of a direct variation. Select two points, other than A, that are elements of this direct

There are 23 pennies on one side of a balance and 17 pennies on the other
side. Levi thinks 3 pennies should be added to the higher pan, Arjan thinks 4
Pennies should be added, and Charlotte thinks 6 pennies should be added. Who Is correct and why?
To have the same number of pennies in both sides, we should add 6 pennies, so Charlotte is correct.
How many pennies should we add?We want to have the same number of pennies on both sides, on one side we have 23 pennies, and in the other 17. So we will add x pennies to the last side, such that we get:
23 = 17 + x
This is a linear equation. To solve it, we need to isolate the variable x, we can do that by subtracting 17 in both sides:
23 - 17 = 17 + x - 17
6 = x
This means that the solution is 6, so we should add 6 pennies, meaning that Charlotte is correct.

Method 1
Apply Difference of Two Squares Formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
Given [tex]x^2-16=0[/tex]
Rewrite 16 as 4²
Therefore, [tex]a^2=x^2[/tex] and [tex]b^2=4^2[/tex]
[tex]\implies a = \sqrt{x^2}=x[/tex]
[tex]\implies b=\sqrt{4^2} =4[/tex]
[tex]\implies x^2-16^2=(x+4)(x-4)[/tex]
[tex]\implies (x+4)(x-4)=0[/tex]
[tex]\implies (x+4)=0 \implies x=-4[/tex]
[tex]\implies (x-4)=0 \implies x=4[/tex]
Method 2
Given equation:
[tex]x^2-16=0[/tex]
Add 16 to both sides:
[tex]\implies x^2-16+16=0 + 16[/tex]
[tex]\implies x^2=16[/tex]
Square root both sides:
[tex]\implies \sqrt{x^2}=\sqrt{16}[/tex]
[tex]\implies x=\pm4[/tex]
Therefore, x = -4, x = 4
