The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 110 feet long. Find the period.
Answers
Answer:
11.73seconds
Step-by-step explanation:
Given the expression of length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth modeled as;
L = 0.81t²
Given
Length of the pendulum = 110feet
Required
Time (period)
Substitute the given value into the formula
L = 0.81t²
110 = 0.8t²
t² = 110/0.8
t² =137.5
t = √137.5
t = 11.73seconds
Hence the period is 11.73seconds

In this diagram, each square represents 1 km. What is the displacement of the car?
Answers
Explanation:
With displacement, all we care about is the beginning and end. We don't care about the middle part(s) of the journey. So we'll take the straight line route from beginning to end when it comes to computing displacement.
We start at A(0,0) and end at B(-2,0). Going from A directly to B has us go 2 km west. Keep in mind that displacement is a vector, so you must include the direction along with the distance.

measure of angle 2: 78 degrees
Step-by-step explanation:
angle 1 + angle 2 = 180 degrees because they are a linear pair.
(x+63)+2x=180 angle1 x+63 or (39)+63 angle2 2x or 2(39)
3x+63=180 39+63= 102 2 x 39 = 78
-63 -63

/3 /3
x=39
Hope this helps :D
Answer:
The measure of angle 1 is: 102
The measure of angle 2 is: 78
Step-by-step explanation:
Write an equation modeling the situation: x+63+2x=180 (It equals to 180 because of the straight line on the bottom)Add like terms: 3x+63=180Subtract 63 from both sides: 3x=117Now divide 117 by 3 to get: x=39Now that you know what x is, substitute 39 where the "x"s are.I hope this helps!!
The Bears have won 7 and tied 2 of their last 13 games. They have not forfeited any games. Which ratio correctly compares their wins to losses?
Answers
Answer:
7:4
Step-by-step explanation:
7:4 because if 13 is the total amount of games, that minus the amount of games won and tied equals the amount of games loss which is 4. Since it says wins to losses, the wins will come first in the ratio. Therefore the correct answer would be 7:4.

7:4

9514 1404 393
Answer:
3. 84 km
4. y = 3/4x
Step-by-step explanation:
3. The map and ground distances can form a proportion:
ground distance / map distance = 24 km / (2 cm) = x / (7 cm)
Multiplying by 7 cm gives ...
x = (24 km)(7/2) = 84 km
The actual distance is 84 km.
__
4. We notice that y (9) is less than x (12), so the multiplier of x must be less than 1. The appropriate equation is ...
y = 3/4x
