Answer:
as below
Step-by-step explanation:
to find the height of the pole recall the relationship of sin cos and tan to the triangle with this helpful mnemonic SOH CAH TOA
Sin = Opp / Hyp
Cos = Adj / Hyp
Tan = Opp / Adj
we will need to solve two triangles and subtract them.
one is the 15° one of the slope of the road and the other is the 57° one that is the angle of the sun. sooooo,
lets solve the 15° one first. We are told that the adj side is 75'
since we know the angle and the adj side and we want to find the Opp side let's use Tan b/c it has all of those in it :)
Tan(15) = Opp / 75
75*Tan(15) = Opp ( I'll put my calculator to work for this )
20.096 = Opp
that's the height of the road to the bottom of the flag pole along that flag pole axis into the ground
next lets solve the 57° triangle in the exact same way
Tan(57) =Opp / 75
75*Tan(57) = Opp
115.4898 = Opp
the tall triangle is the one that goes all the way into the ground, the small one is the one that is under the ground
so subtract the small one from the big one to find the height of the flag pole above the ground
115.4898-20.096 = 95.3938
so the flag pole is about 95.4 feet tall
:o that's pretty tall :

Step-by-step explanation:
The correct type of dilation for given scale factors are 1) contraction, 2) contraction, 3) expansion 4) contraction
What is dilation?Dilation is a type of transformation in geometry, in which the original figure changes its scales, either reduce or enlarge.
Given are scale factors,
Scale factor symbolized by k,
We know that, when k > 1, the figure expands or enlarge.
When k < 1, the figure reduces or contract.
And when k = 1, the figure is congruent to the dilation.
1) -5 = (contraction)
1 > -5, therefore, figure is contraction.
2) -1/4 = (contraction)
1 > -1/4, therefore, figure is contraction.
3) 3.5 = (expanding)
1 < 3.5, therefore, figure is expanding.
4) 6/7 = (contraction)
6/7 = 0.8571 < 1, therefore, figure is (contraction)
Hence, -5 = (contraction), -1/4 = (contraction), 3.5 = (expanding) and 6/7 = (contraction)

Are the functions u(x),v(x) orthogonal on [−1,1] ? Verify that ∥u(x)∥=52 and that ∥v(x)∥=7/2
Thus answer is ∥u(x)∥ = 2√(65)/5 and ∥v(x)∥ = √(7/2).
To verify if two functions u(x) and v(x) are orthogonal on the interval [−1,1], we need to check if their inner product over that interval is zero. The inner product of two functions u(x) and v(x) is given by:
⟨u,v⟩ = ∫[−1,1] u(x)v(x) dx
Let's calculate the inner product and check if it equals zero:
∫[−1,1] u(x)v(x) dx = ∫[−1,1] (x^3 - x) (3x^2 + 1) dx
Expanding and integrating:
∫[−1,1] (3x^5 + x^3 - 3x^3 - x) dx = ∫[−1,1] (3x^5 - 2x^3 - x) dx = 0
Since the inner product is zero, we can conclude that the functions u(x) and v(x) are orthogonal on the interval [−1,1].
Next, let's calculate the norms of u(x) and v(x):
∥u(x)∥ = √(∫[−1,1] (x^3 - x)^2 dx) = √(52/5) = √(260/25) = 2√(13/5) = 2√(65)/5
∥v(x)∥ = √(∫[−1,1] (3x^2 + 1)^2 dx) = √(7/2)
Therefore, ∥u(x)∥ = 2√(65)/5 and ∥v(x)∥ = √(7/2).

there are two boxes. box 1 contains four red balls and two white balls. box 2 contains three red and three white balls. one ball is drawn from box 1, hidden from view, and then placed in box 2 (so that box 2 now has seven balls). then a ball is drawn from box 2. (you can assume that whenever a ball is drawn from a box, eqch ball in the box is equally likely to be drawn.)
The probability of drawing a red ball from box 2 after the transfer is 4/7.
What is the probability of drawing a red ball from box 2 after one red ball is transferred from box 1?After transferring one red ball from box 1 to box 2, box 2 contains a total of 7 balls. Out of these 7 balls, 4 are red (3 from box 2 initially and 1 transferred from box 1) and 3 are white (3 from box 2 initially and none transferred from box 1).

Concepts and Skills Bennet has 8 blue marbles, 7 green marbles, 15 red marbles, and 20 yellow marbles in a bag. He randomly selects a marble 200 times. He replaces the marble after each selection. Predict how many times Bennet will select a red marble. A) about 30 times B about 50 times Cabout 60 times D about 120 times
With probability we can predict that, Bennet will select a red marble about 60 times in 200 draws, which corresponds to option C.
What is probability?Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain.
According to given information:The probability of selecting a red marble on any given draw is the number of red marbles divided by the total number of marbles in the bag:
P(Red) = 15 / (8 + 7 + 15 + 20) = 15 / 50 = 0.3
Since Bennet is replacing the marble after each selection, each draw is independent and has the same probability of selecting a red marble. Therefore, the number of red marbles selected in 200 draws follows a binomial distribution with n = 200 (the number of trials) and p = 0.3 (the probability of success on each trial).
The expected value of the number of red marbles selected can be found using the formula:
E(X) = np
where X is the number of red marbles selected, n is the number of trials, and p is the probability of success on each trial.
Substituting the values we get:
E(X) = 200 * 0.3 = 60
Therefore, we can predict that Bennet will select a red marble about 60 times in 200 draws, which corresponds to option C.

Use the Exterior Angle Theorem to find the measure of each angle.
Answer: <C = 32, <D = 80, <DEC = 68
Step-by-step explanation:
First, the exterior angle DEF equals the sum of the two other interior angles that are not adjacent to it, meaning that the angle DEF equals the sum of angles DCE and EDC.
Therefore, you get the equation
2y+8+6y+8=112
8y+16=112
8y = 96
y = 12
Since y is 12, let's use this to find the measure of the other angles.
DCE = 2y+8 = 32
EDC = 6y+8 = 80
Angle DEC equals 180 - 112 = 68

Answer:
12173
Step-by-step explanation:
1 21 73
3 | 365²19
Long division:
Starting from the first digit of the number being divided (i.e. 36519), move along dividing each digit by 3;
If the digit cannot be divided by 3 perfectly, the remainder should be in the next position of value to the next digit in the sequence, so for the above calculation:
First digit is 3, 3/3 = 1, so write the number 1 above;
There is no remainder so simply move to next digit;
The second digit in the number is 6, 6/3 = 2, so write 2 above, next to the previous 1;
Once again, no remainder so move on;
Third digit is 5, 5/3 = 1 with a remainder of 2, so we write 1 above, next to the previous 2 and the remainder of 2 will be placed before the next digit in the number, which is 1;
Understand, this 2 is not to be added to the digit, like 1 + 2, but rather should be added at the next higher position of value (i.e. multiplied by 10), so it will be 1 + 20, which is 21;
Now, we continue as previously, 21/3 = 7, so 7 should be written above, next to the 1;
There is no remainder, so move on;
Last digit is 9, 9/3 = 3 so this written next to the 7 above;
There is no remainder;
There are no more digits and no remainder to deal with so the division is complete;
The number above is the answer.

451) Given the two 3-D vectors a-[7, -2, 2] and b-[-7, -1, 4]. find the dot product and angle (degrees) between them. Also find the cross product (d = a cross b) and the unit vector in the direction of a. ans:8
The dot product of vectors a and b is 8. The angle between vectors a and b is 90 degrees. The cross product of vectors a and b is [6, -34, -12]. The unit vector in the direction of vector a is [0.845, -0.241, 0.241].
The dot product of two vectors a and b is calculated by multiplying their corresponding components and summing them up. For vectors a-[7, -2, 2] and b-[-7, -1, 4], the dot product is (7 * -7) + (-2 * -1) + (2 * 4) = 49 + 2 + 8 = 59.
The angle between two vectors can be found using the formula:
cos(theta) = (a dot b) / (|a| * |b|)
In this case, |a| is the magnitude of vector a and |b| is the magnitude of vector b. Since both vectors have the same magnitude of sqrt(7^2 + (-2)^2 + 2^2) = sqrt(53), the equation simplifies to:
cos(theta) = (a dot b) / (53)
The angle theta can be found by taking the inverse cosine of cos(theta). In this case, the angle between vectors a and b is 90 degrees.
The cross product of two vectors a and b is calculated using the formula:
d = (a2b3 - a3b2, a3b1 - a1b3, a1b2 - a2b1)
For vectors a-[7, -2, 2] and b-[-7, -1, 4], the cross product is:
d = (2 * (-1) - 2 * 4, 2 * (-7) - 7 * 4, 7 * (-1) - (-2) * (-7))
= (-2 - 8, -14 - 28, -7 - 14)
= (-10, -42, -21)
To find the unit vector in the direction of vector a, we divide vector a by its magnitude:
|a| = sqrt(7^2 + (-2)^2 + 2^2) = sqrt(53)
Unit vector = a / |a| = [7/sqrt(53), -2/sqrt(53), 2/sqrt(53)] = [0.845, -0.241, 0.241]
Therefore, the dot product of vectors a and b is 59, the angle between vectors a and b is 90 degrees, the cross product of vectors a and b is [-10, -42, -21], and the vector in the direction of vector a is [0.845, -0.241, 0.241].

Each side of a rhombus is 10 cm long and one of its diagonals measures 16cm. Find the length of the other diagonal
The length of the other diagonal is 22.36 cm.
What is diagonals ?Diagonal is defined as a sloping line or the slant line, that connects to the vertices of a shape.
Let's call the length of the other diagonal "d".
Since a rhombus has perpendicular diagonals that bisect each other
we can use the Pythagorean theorem to find the length of the other diagonal:
d^2 = 10^2 + 10^2 = 100
d = sqrt(100) = 10 * sqrt(10) = 10 * 2.236 = 22.36 cm
