2. You are standing 15 feet from a tree. You want to get an apple from the tree using a ladder that is 25 feet long. What is the height of the tree? What is the angle of elevation?
Answer:
h = 20 ft
theta =53.13010235
Step-by-step explanation:
First we can find the height by the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs
15^2 + h^2 = 25^2
225 + h^2 = 625
h^2 = 625 - 225
h^2 = 400
Taking the square root of each side
h = 20 ft
Now using trig functions
cos theta = adj side / hyp
cos theta = 15/25
Taking the inverse cos of each side
cos^-1 ( cos theta) = cos^-1 ( 15/25)
theta =53.13010235

According to the graph, what is the factorization of x2 - 6x + 5?
A. (x + 5)(x+1)
B. (x - 5)(x+ 1)
C. (x - 5)(x - 1)
D. (x + 5)(x - 1)
The factorization of x2 - 6x + 5 is (x - 1)(x -5)
How to determine the factorization?From the graph, the zeros of the function are:
x = 1 and x = 5
Set the zeros to 0
x - 1 = 0 and x - 5 = 0
Multiply the zeros
(x - 1)(x -5) = 0
Hence, the factorization of x2 - 6x + 5 is (x - 1)(x -5)

Answer:
See below
Step-by-step explanation:
Part (a)f(x - 1) is the translation of f(x) one unit right.
So the graph is exactly same shape but shifted right one unit.
Part (b)f(x) has vertex (-1, 2)
The function y = f(-x) + 2 will have the vertex changed as per rule:
(x, y) → (-x, y + 2)So the new vertex is:
(-1, 2) → (-(-1), 2 + 2) = (1, 4)Suppose that 3 balls will be randomly put into 3 buckets, with each ball being equally likely to be put into each of the buckets, independently of which buckets are chosen for any of the other balls. (E.g., the first ball is equally likely to be put into any of the 3 buckets, and then regardless of which bucket the first ball is placed in, the second ball is equally likely to be put into any of the 3 buckets.) What is the probability that all of the balls will be put into the same bucket
Answer:
[tex]\frac{1}{27}[/tex]
Step-by-step explanation:
Since there are a total of three buckets and only one can be chosen at a time, this would mean that the probability of a ball being placed in a bucket is 1/3. Since each ball has the same probability of being placed into any bucket regardless of the where the previous ball landed, it means that each ball has the same 1/3 probability of a bucket. In order to find the probability that all three land in the same bucket, we need to multiply this probability together for each one of the balls like so...
[tex]\frac{1}{3} * \frac{1}{3} * \frac{1}{3} = \frac{1}{27}[/tex]
Finally, we see that the probability of all three balls landing in the same bucket is [tex]\frac{1}{27}[/tex]

A. preserves length, angle measures and distance between points
B. preserves length and angle measures but not distance between points
C. is a transformation that changes the size of the figure
is a transformation with its image and pre-image not being congruent
Answer: A. preserves length, angle measures and distance between points
Rigid motions or isometries are any of the three transformations below
translation (aka shifting)rotationreflectionAny of those three transformations will keep the figure the same size and shape. That means distances between any two points are kept the same, and angle measures are kept the same as well. Everything is kept the same. The only difference is that the figure is in a different location, is rotated somehow, or it is reflected some way. You can use a series of transformations to undo everything to get the original figure back.
If you wanted to change the size of the figure, then you would apply dilation, which isn't an isometry.

3y+x=5, x-3y=12, y=3x-2, 6y-2x=7 which two of these are parallel??
Answer:
2nd and 4th are parallel
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y + x = 5 ( subtract x from both sides )
3y = - x + 5 ( divide terms by 3 )
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{1}{3}[/tex]
-------------------------------------------------------
x - 3y = 12 ( subtract x from both sides )
- 3y = - x + 12 ( divide terms by - 3 )
y = [tex]\frac{1}{3}[/tex] x - 4 ← in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
-------------------------------------------------------
y = 3x - 2 ← in slope- intercept form
with slope m = 3
---------------------------------------------------------
6y - 2x = 7 ( add 2x to both sides )
6y = 2x + 7 ( divide terms by 6 )
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{6}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
--------------------------------------------------------
Parallel lines have equal slopes.
The 2nd and 4th have equal slopes and are parallel

The formula for X's cumulative distribution function (CDF) is
a. Probability P(X≤3) = P(X=1) + P(X=2) + P(X=3) = 1/7 + 1/14 + 3/14 = 5/14
b. P(X<3) = P(X=1) + P(X=2) = 1/7 + 1/14 = 3/14
c. P(X<4.12|X>1.638) = P(2<X<4.12)/P(X>1.638) = [P(X=3)+P(X=4)]/[1-P(X=1)] = (3/14)/(11/14) = 3/11
d. The cumulative distribution function of X, for x = 5, F(5) = 1
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Here, we have,
a. Probability P(X≤3) = P(X=1) + P(X=2) + P(X=3) = 1/7 + 1/14 + 3/14 = 5/14
b. P(X<3) = P(X=1) + P(X=2) = 1/7 + 1/14 = 3/14
c. P(X<4.12|X>1.638) = P(2<X<4.12)/P(X>1.638) = [P(X=3)+P(X=4)]/[1-P(X=1)] = (3/14)/(11/14) = 3/11
d. The formula for X's cumulative distribution function (CDF) is
F(x) = P(X < x)
For x = 1, F(1) = 1/7
For x = 2, F(2) = 1/7 + 1/14 = 3/14
For x = 3, F(3) = 1/7 + 1/14 + 3/14 = 5/14
For x = 4, F(4) = 1/7 + 1/14 + 3/14 + 2/7 = 11/14
For x = 5, F(5) = 1
As a result, X's CDF is:
F(x) = {1/7, x < 1
3/14, 1 ≤ x < 2
5/14, 2 ≤ x < 3
11/14, 3 ≤ x < 4
1, x ≥ 4}
