an 18 foot ladder rests against molding at the top of 15 feet building. what is the angle of elevation from the ground to the top of the ladder? Round to the nearest degree.
The angle of elevation is ____
Answers
Answer:
To find the angle of elevation, we can use the inverse tangent function (arctan). The angle of elevation is the angle between the ground and the line of sight from the ground to the top of the ladder.
Let's calculate it:
Angle of elevation = arctan(opposite/adjacent)
Angle of elevation = arctan(15 feet / 18 feet)
Using a calculator or table of trigonometric functions, we can find the arctan of (15/18) to be approximately 41.19 degrees.
Rounded to the nearest degree, the angle of elevation from the ground to the top of the ladder is 41 degrees.

in coin changing problem, show that the greedy strategy fails for the denominations 25, 20, 10, 5, and 1 cents. (hint: prove that we cannot construct the solution by making decisions to choose each item to add to the solution optimally, and never reversing decisions already made
Answers
In coin changing problem, the greedy strategy fails for the denominations 25, 20, 10, 5, and 1 cents.
The greedy algorithm for the coin change problem (pay a certain amount with the fewest number of coins feasible) is effective. It always chooses the coin with the largest denomination that does not exceed the remaining sum, and it consistently determines the right answer for certain coin sets.
But for certain set of denominations, it fails. For example take a sum of 44 cents then by greedy algorithm, first taking the highest denominations one 25 cent is taken and now 19 is remaining. So now one 10 cent is taken, and 9 is remaining. Now, one 5 cent is taken and four 1 cent is taken. So total we get 7 coins.
Now let us deviate from greedy algorithm and take two 20 cents, now 4 is remaining. So now four 1 cent is taken, this sums up only 6 coins. So this is a much optimal solution than the one obtained by greedy algorithm.

Can we find a unique price for an apple and an orange?
Answers
Answer:
no
Step-by-step explanation:
The prices are inconsistent, so there is no unique price that can be set for either an apple or an orange that will give the total prices indicated.
__
The first relation can be written as ...
$10 = 4A +4O
$10 = 4(A +O) . . . . factor out 4
$2.50 = A +O . . . . divide by 4
The second relation can be written as ...
$12 = 6A +6O
$12 = 6(A +O) . . . . factor out 6
$2 = A +O . . . . . . . divide by 6
These two relations give different prices for 1 apple and 1 orange. There is no price that can be set for either fruit that will give this result.

How many paths are there from $A$ to $B,$ if you travel along the edges? You can travel along each edge at most once, but you can pass through the same point more than once. (You can pass through $B,$ as long as you end up at the point $B.$)
Answers
Answer:

Step-by-step explanation:
You don't need to pass through each edge once.
If we name the top vertex 1 and the bottom vertex 2 then here are the possible combinations:
A-1-B
A-B
A-2-B
A-1-B-A-2-B
A-2-B-A-1-B
A-B-1-A-2-B

x=2-33x=-2-4x=2x+7-5x=4x+6-7A signal flare is fired into the air from a boat. The height h of the flare in feet after t seconds is h = -16t2 + 160t. How high will the flare travel? When will it reach this maximum height? When will the flare hit the water? After 8 seconds is the flare going up on coming down? How high is it at that time? Approximately how many seconds is the flare above 250 feet? Summary of what’s happening in the problem
Answers
The equation that models the height of the flare is a quadratic equation, then the maximum height corresponds to the vertex.
The vertex of a quadratic equation is found as follows:
\(t_V=\frac{-b}{2\cdot a}\)where a and b are the first two coefficients of the quadratic equation, and tv is the time at which the maximum height is reached. In this case, a = -16, and b = 160, therefore:
\(\begin{gathered} t_V=\frac{-160}{2\cdot(-16)} \\ t_V=\frac{-160}{-32} \\ t_V=5\text{ seconds} \end{gathered}\)To find the height we need to replace this time t into the equation as follows:
\(\begin{gathered} h_V=-16t^2_V+160t_V \\ h_V=-16\cdot5^2+160\cdot5 \\ h_V=-400+800 \\ h_V=400\text{ ft} \end{gathered}\)How high will the flare travel? 400 ft.
When will it reach this maximum height? After 5 seconds.
If the flare hits the water, the heigh is of the flare is zero, then:
\(\begin{gathered} h=-16t^2+160t \\ \text{ Taking 16t as common factor} \\ 0=16t(-t+10) \\ \text{ This equation has two solutions:} \\ 16t=0 \\ t_1=0 \\ Or \\ -t+10=0 \\ 10=t_2 \end{gathered}\)When will the flare hit the water? After 10 seconds
After 8 seconds is the flare going up on coming down? Going down. 8 seconds comes after the maximum height and before the flare reaches the water.
To find the height at time = 8 seconds, we need to replace this time t into the equation as follows:
\(\begin{gathered} h=-16\cdot8^2+160\cdot8 \\ h=-1024+1280 \\ h=256\text{ ft} \end{gathered}\)How high is it at that time? It is at 256 ft high.
To find the time elapsed when the height, h, is 250 ft, we need to replace this value into the quadratic equation and solve for time, t.
\(\begin{gathered} 250=-16t^2+160t \\ 0=-16t^2+160t-250 \end{gathered}\)Using the quadratic formula:
\(\begin{gathered} t_{1,2}=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ t_{1,2}=\frac{-160\pm\sqrt[]{160^2-4\cdot(-16)\cdot(-250)}}{2\cdot(-16)} \\ t_{1,2}=\frac{-160\pm\sqrt[]{9600}}{-32} \\ t_1\approx\frac{-160+98}{-32}\approx1.9\text{ seconds} \\ t_2\approx\frac{-160-98}{-32}\approx8\text{ seconds} \end{gathered}\)The flare reaches this heigth after approximately 1.9 seconds, after this, it is above this height until 8 seconds elapsed from the beginning.
Approximately how many seconds is the flare above 250 feet? 6.1 seconds (= 8 - 1.9).
Summary of what’s happening in the problem. At the beginning the flare is at the level of the water (at t = 0, h = 0). Then its height, h, starts to increase until it reaches its maximum of 400 ft high, after 5 seconds (when t = 5, h = 400). Next, the flare starts to fall down until it reaches the water, this happen after 10 seconds (at t = 10, h = 0).

What is y-intercept?The y-intercept is the point where a function or a curve intersects the y-axis. In other words, it is the value of the dependent variable (y) when the independent variable (x) is equal to zero.
In the form, f(x) = 1/2 x² - 5x + 21/2 it is easier to see that eliminating x by plugging in 0 leaves 21/2 which is the y intercept

Answer:
Just some background:
Congruent means that a triangle has the same angle measures and side lengths of another triangle.
SAS congruence theorem: If two sides and the angle between these two sides are congruent to the corresponding sides and angle of another triangle, then the two triangles are congruent. Congruent triangles: When two triangles have the same shape and size, they are congruent.
Let's look at A first.
The triangle on left, we know 40 and 30 degree angles. So 3 all angles together = 180, so the 3rd angle = 180-30-40 = 110.
Now look at the triangle on the right. The angle shown is 110! This angle is between the sides marked with || and ||| marks, indicating that those two sides are the same length between both triangles.
Therefore both triangles are the same by Side-Angle-Side or SAS.
Now look at B.
It's a right triangle. We are missing 1 side of each triangle.
Let's solve for the missing "leg" of the triangle on the right. The pythagorean theorem says that a^2 + b^2 = c^2 where a and b are the 'legs' or sides of the triangle and c is the hypotenuse (always the longest length opposite the right angle).
so 2^2 + b^2 = 4^2
4 + b^2 = 16
b^2 = 16-4
b^2 = 12
That missing side is the \(\sqrt{12}\).
This does NOT match the triangle on the left.
Theses two triangles are NOT congruent.

Answers
The vertical displacement is of 2 units down, the correct option is B.
What is the vertical displacement?Remember that for a function f(x), a vertical displacement of N units is written in general form as:
g(x) = f(x) + N
If N > 0, the translation is upwards.
if N < 0, the translation is downwards.
Here we assume that we start with the parent cosine function:
y = cos(x)
And the transformed function is:
y = -2 - cos(x - π)
So we have some transformations, but the vertical translation is of 2 units down. So the correct option is B.
