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 50 feet long. Find the period.
Answer:
7.86seconds
Step-by-step explanation:
Given the expression used to model the length of the pendulum as
L=0.81t^2 where t is the period
IF the pendulum is 50 feet long, then L = 50 feet
Substitute
50 = 0.81t^2
t² = 50/0.81
t² = 61.7283
t = 7.86 seconds
Hence the period is 7.86seconds

Describe three ways to transform the graph of f(x) = log x to obtain the graph of g(x) = log 100x -1. Justify your answer.
Answer:
Translation up by one unitStep-by-step explanation:
Given
f(x) = log xLet's see what relationship has the function g(x) and f(x):
g(x) = log 100x - 1 = log 100 + log x - 1 = 2 + log x - 1 = log x + 1 = f(x) + 1g(x) = f(x) + 1As we see the function g(x) is the translation of the function f(x) up by one unit
Note: there is one transformation as described above. The interim steps in the solution could possibly be considered as different ways (like two units up and one unit down). The final position is just one way translation.

=======================================================
Explanation:
The first number along the top is 40, and it multiplies with the second number along the side to get 40 x 5 = 200
You can think of it as 4 x 5 = 20, then you tack on an extra 0 to the '4' and to the '2' as well, so it keeps things balanced.
So this explains how choice D is one of the answers.
-------------------------
After 200 fills in that question mark, we'll have these four numbers inside the table: 2400, 420, 200, and 35
Those four values add up to: 2400+420+200+35 = 3055
This shows that choice A is one of the answers.
--------------------------
Finally, choice E is the third answer because along the top we have 40+7 = 47, and along the side we have 60+5 = 65
Put another way, the total top length is the sum of the two smaller pieces of 40 and 7, which explains how the total top length is 47 units long. A similar argument happens for the left side values as well.
We ultimately have a rectangle that is 47 units across in the horizontal direction, and 65 units tall in the vertical direction.
With your calculator, you should note that 47*65 = 3055 to help confirm everything lines up.
--------------------------
Extra info:
Choice B is false because this contradicts choice D.
Choice C is false because it contradicts choice E
100 POINTS!!!! The median of the set of numbers 12, 38, 45, $x$, 14 is five less than the mean. If x is a negative integer, what is the value of x?
Answer:
-14
Step-by-step explanation:
Since x is negative, the median of the set is 14. Therefore, the mean of the set is 14 + 5 = 19, and its sum is 19 · 5 = 95. Since 12, 38, 45, and 14 sum to 109, the remaining integer x must be 95 − 109 = −14 .
Answer:
x = -14Step-by-step explanation:
Given set of numbers:
12, 38, 45, x, 14Put them in ascending order, considering the x is negative
x, 12, 14, 38, 45The median is 14
The mean is 5 greater than median:
14 + 5 = 19The mean is calculated:
(x + 12 +14 + 38 + 45)/ 5 = 19x + 109 = 19*5x = 95 - 109x = -14Plz guyss helpp;(

Scott is 72 inches tall and Chris is 185 centimeters tall who is taller I know that Chris is taller but how tall is Chris in inches?
Answer: Chris is taller by 5 inches.
Step-by-step explanation:
You need to convert one of them to the other's unit of measurement so as to be able to measure effectively.
Assuming we convert to inches.
An inch is 2.54 cm.
Since Chris is 185 cm tall, Chris's height in inches is:
= 185 / 2.4
= 77 inches
Chris is therefore taller by 5 inches.

The sides of a triangle formed a geometric progression with a ratio r. For what values of r, it is possible?
Answer:
ok so i really shouldnt get points for this, but i wanted to help. The person who solved the problem here: https://math.stackexchange.com/questions/2911546/suppose-the-sides-of-a-triangle-form-a-geometric-progression-with-common-ratio-r is correct, but it is not very clear. Basically, he rounded to the third decimal point (since a sqrt has infinate decimals), and this might have been what got you the wrong answer. Basically the important thing is that r has to be between the (-1+√5)/2 and (1+√5)/2, or (-1+√5)/2 < r < (-1+√5)/2
Is x = 5 a solution of the inequality x - 3<2 ? Explain
Answer:
No
Step-by-step explanation:
Plug in 5 for x
5 - 3<2
2<2
this is not true it should be equal to 2.
Answer:
Not a solution
Step-by-step explanation:
Plug in x = 5 in the equality,
x - 3 = 5 - 3 = 2 not < 2
So, x = 5 is not a solution
How many square feet of outdoor carpet will we need for this hole? 12ft , 2ft, 2ft, 4ft
Answer:
44 ft^2
Step-by-step explanation:
so first, you get the area for the outer rectangle
12*4=48
so the area is 48, but there is a 2x2 square cut out so subtract that area
2*2=4
48-4=44

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 16 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer: 8.25cm
Step-by-step explanation:
Use Pythagorean's Theorem for a right triangle:
[tex]a^2+b^2=c^2[/tex]
'A' and 'B' being the legs and 'C' being the hypotenuse.
[tex]16^2+b^2=18^2\\256+b^2=324\\b^2=68\\b=\sqrt{68}=8.25cm[/tex]

Step-by-step explanation:
"Identify the like terms in the expression 10x+5+3x+1." I wasnt paying attention and so I dont know the answer help
Answer:
Simplifying
10x + -5(3x + -1) = 15
Reorder the terms:
10x + -5(-1 + 3x) = 15
10x + (-1 * -5 + 3x * -5) = 15
10x + (5 + -15x) = 15
Reorder the terms:
5 + 10x + -15x = 15
Combine like terms: 10x + -15x = -5x
5 + -5x = 15
Solving
5 + -5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + -5x = 15 + -5
Combine like terms: 5 + -5 = 0
0 + -5x = 15 + -5
-5x = 15 + -5
Combine like terms: 15 + -5 = 10
-5x = 10
Divide each side by '-5'.
x = -2
Simplifying
x = -2

Uma pessoa comprou um terreno quadrado 81 m2 e deseja aumentar 19 m2 na area dele de que maneira ele continue em forma de quadrado qual sera o perímetro desse terreno
Answer:
the new perimeter of the land is 40m
Step-by-step explanation:
The computation of the new perimeter of the land is given below:
Since the square plot is 81m^2
It could be increased by 19m^2
So the total would be
= 81m^2 + 19m^2
= 100m^2
Each side is 10m
Now the perimeter is sum of all sides
= 10m + 10m + 10m + 10m
= 40m
hence, the new perimeter of the land is 40m

Two numbers have these properties. * Both numbers are greater than 6 * Their highest common factor (HCF) is 6 * Their lowest common multiple (LCM) IS 60 Find the two numbers
Answer:
The two numbers are 12 and 30
Step-by-step explanation:
It is given that both the numbers are greater than 6
Let the two numbers be X and Y
As we know
X * Y = LCM * HCF
XY = 360
Let us list down some combinations of X and Y and test above conditions
There can be following pairs
a) 6,60
b) 18,20
c) 24,15
d) 12,30
LCM of the two numbers is 60 and both the numbers are greater than 6
So only 12, 30 satisfy the set condition.

how do you solve for range because i’m so confused lol
Answer:
A) y ≥ -4
Step-by-step explanation:
The range of a function basically represents all of the y values that a function encompasses (I hope that makes sense, if not, please let me know).
In this graph, since the parabola has a vertex at (1, -4), the range includes y values only greater than or equal to -4. The function does not include y values lower than -4. Therefore, the range must be y ≥ -4.
Triangle A: 6 cm, 8 cm, and 10 cm Triangle B: 310 in, 25in, and 35in Triangle C: 8 ft, 15 ft, and 17 ft Triangle D: 0.32 mm, 0.96 mm, and 1 mm Which of the four triangles is obtuse
Answer:
Triangle B
Step-by-step explanation:
For a triangle with sides a, b and c,
If c² = a² + b²
Then triangle will be a right triangle.
If c² > a² + b²
Triangle will be an obtuse triangle
If c² < a² + b²
Triangle will be an acute triangle.
By applying these properties in the given triangles,
Triangle A:
6 cm, 8 cm and 10 cm
6² + 8² = 36 + 64
6² + 8² = 100 [c² = a² + b²]
Therefore, it's a right triangle.
Triangle B:
310 in, 25 in and 35 in
25² + 35² = 625 + 1225
= 1850
Since, 310² = 96100
And 96100 > 1850 [c² > a² + b²]
Therefore, It's an obtuse triangle.
Triangle C:
8 ft, 15 ft and 35 ft
8² + 15² = 64 + 225
= 289
Since, 17² = 289 [c² = a² + b²]
Therefore, It's a right triangle.
Triangle D:
0.32 mm, 0.96 mm and 1 mm
(0.32)² + (0.96)² = 1.024
Since, 1² = 1
And 1 < 1.024 [c² < a² + b²]
Therefore, triangle will be an acute triangle.
