The tip of a pendulum moves through an angle of 0.38 radians. If the radius of the pendulum is 25
centimeters, then which of the following is the length of the arc the tip moves through?
(1) 4.7
(3) 7.8
(2) 6.1
(4) 9.5
Answers
Answer:
The length of arc 'l' = 9.5
Step-by-step explanation:
Explanation:-
Given radius of the pendulum r = 25
The tip of a pendulum moves through an angle of 0.38 radians
θ = 0.38 radians
The length of arc 'l' = rθ
'l' = (25)(0.38)
The length of arc 'l' = 9.5

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Step-by-step explanation:
let the number be: x
then,
6x+7 = 55
6x = 55-7
6x = 48
x = 48/6
x = 8

Answer:
(D) 85 cm².
Step-by-step explanation:
To find the area of a triangle, we can use the formula:
Area = (1/2) x base x height
In this case, we are given the lengths of three sides of the triangle, but we need to find the height. One way to do this is to use Heron's formula to calculate the area directly, but another approach is to use the Pythagorean theorem to find the height.
We can see that the side lengths of the triangle are 17 cm, 10 cm, and 9 cm. Let's assume that the side of length 17 cm is the base of the triangle. Then, we can draw an altitude from the vertex opposite the base to the base, creating two right triangles. The height of the triangle is the length of this altitude.
Using the Pythagorean theorem in one of the right triangles, we can solve for the height as follows:
(Height)^2 = (10 cm)^2 - (4.5 cm)^2
Height = sqrt[(10 cm)^2 - (4.5 cm)^2]
Height = sqrt[100 cm^2 - 20.25 cm^2]
Height = sqrt(79.75) cm
Height ≈ 8.93 cm
Now that we have the base and height of the triangle, we can use the formula for the area of a triangle:
Area = (1/2) x base x height
Area = (1/2) x 17 cm x 8.93 cm
Area ≈ 76.025 cm²
Therefore, the area of the triangle is approximately 76.025 cm². None of the answer choices match this result exactly, but the closest option is (D) 85 cm².
Answer:
A
Step-by-step explanation:
The formula of a triangle is Base x Height ÷ 2 = Area
10 x 9 = 90 sq cm
90 ÷ 2 = 45

Answer: y = -5.5x +18
Step-by-step explanation: -11/2 = 5.5
Answer: y= -11/2x + 7
Step-by-step explanation:
(2,7) and (4,-4)
Do \(\frac{y^{2} - y^1}{x^2-x^1} \\\) so it should look like this \(\frac{-4-7}{4-2} =\frac{-\\11}{2}\)
\(\frac{-11}{2}\) is your slope
Then you need to find your "b" term.
\(-4=\frac{-11}{2} (2) +b\)
Multiply -11/2 by 2 and add 11 to both sides
Then do -4 + 11 which equals 7
So 7 is your b term
So your answer is y= -11/2 + 7

Answers
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
\(a^{x} * a^{y} = a^{x+y}\)
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
\(a^{x} / a^{y} = a^{x-y}\)
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
\((a^{x)^{y} } = a^{xy}\)
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
\((ab)^{x} = a^{x} b^{x}\)

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.
