Answer:
0
Step-by-step explanation:
So,0= the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.
Hence, the values for different conditions were calculated with the help of trigonometric functions.
Part A
θ=kπ
Where k is an integer k=0,1,2..
Part B
θ=[tex]k\frac{\pi }{2}[/tex]
Where k is an integer k=0,1,2..
Part C
θ=kπ
Where k is an integer k=0,1,2..
What is trigonometric function?The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths
Part A
Given that,
f(x)=2sinθ+[tex]\sqrt{2}[/tex]
Non compressed length = [tex]\sqrt{2}[/tex]
Then
2sinθ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]
2sinθ=0
sinθ=0
Therefore θ is the integer multiple of π
θ=kπ
Where k is an integer k=0,1,2..
Part B
Here angle is doubled
Then,
2sin2θ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]
2sin2θ=0
sin2θ=0
Here θ will be the integer multiple of [tex]\frac{\pi }{2}[/tex]
θ=[tex]k\frac{\pi }{2}[/tex]
Where k is an integer k=0,1,2..
Part C
g(x)=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]
Here
f(x)=g(x)
2sinθ+[tex]\sqrt{2}[/tex]=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]
2sinθ=1-[tex]cos^{2}[/tex]θ
we know that [tex]1-cos^{2}[/tex]θ=[tex]sin^{2}[/tex]θ
2sinθ=[tex]sin^{2}[/tex]θ
sinθ=0
Therefore θ is the integer multiple of π
θ=kπ
Where k is an integer k=0,1,2..
Hence, we have solved that
Part A
θ=kπ
Where k is an integer k=0,1,2..
Part B
θ=[tex]k\frac{\pi }{2}[/tex]
Where k is an integer k=0,1,2..
Part C
θ=kπ
Where k is an integer k=0,1,2..

Dean and his friends went to Aqua World Water Park, where they floated down the Lazy River for 1 2 of an hour. This was 1 4 of the total time Dean and his friends spent at Aqua World. Use an equation to find the total amount of time Dean and his friends spent at the park. To write a fraction, use a slash ( / ) to separate the numerator and denominator.
can some one please help me?
Answer:
here's a tip: (use the equation to get the triangle area/length, then find the surface area of the entire thing). Anyways, I think the answer might be ether 268m squared or 853m squared.

(1d) Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon. How long is the BLUE ribbon if the length of the RED ribbon is 12 inches? *
Answer:
19 inches
Step-by-step explanation:
Since the blue ribbon needs to be 7 inches longer than the red ribbon, add 7 to 12 to get 19 inches total.
Hopefully this helps- let me know if you have any questions!
Hey there!
Let's make an equation 28evbar01

A bag contains tiles of different colors. Roshan randomly selects a tile from the bag and returns the tile to the bag after recording the color. He picks a green tile 6 times, a red tile 20 times, a blue tile 7 times, a purple tile 8 times, and a black tile 4 times. Based on the results, what is the theoretical probability that the next tile Roshan picks will be green?
Answer:
6/41
Step-by-step explanation:
6 + 7 + 20 + 8 = 41 so that is number of tiles he took. 6 of those were 41 so therefore, the chance is 6/41
Answer:
There are four red marbles and six blue marbles in all, for a total of ten marbles.
Without replacement, the probability of the first marble being blue is 6/10, while the probability of the second marble being red is 4/9.
The probability of both events occurring is reduced to 4/15 by multiplying 6/10 * 4/9 = 24/90.

can u help please? i don't understand this
Answer:
D
Step-by-step explanation:
To do this you need to simplify (4^3)^5
To do this, simply multiply the powers
So, it would be 3x5
3x5=15
so the answer would be 4^15, which is D
Answer:
4^15
Step-by-step explanation:
( 4^3 )^5
Formula : -
( a^m )^n = a^(mn)
Here,
a = 4
m = 3
n = 5
( 4^3 )^5
= 4^( 3*5 )
= 4^15

Two ways we can solve this problem:
1. Graphically
2. Mathematically
Because you already solved it graphically, I will show you how to do so mathematically. Of course, graphically is much much easier and more efficient in this problem.
Let's break the problem down.
First, we are given a graph which contains a slope.
To find slope, we use the technique -> rise/run
Picking 2 obvious points from the graph, we can see
1st point -> (10, 20)
2nd point -> (40, 80)
Now, let's find the slope
[tex]\frac{80-20}{40-10} = \frac{60}{30} = 2[/tex]
Now, we have an equation y = 2x, where y = number of pies and x = cups of sugar
We want to find how many cups of sugar we need to bake 80 pies. Simply substitute 80 = number of pies = y
y = 2x -> 80 = 2x
Solving for x, divide both sides by 2
40 = x
We need 40 cups of sugar.

Answer:
A.
Step-by-step explanation:
The formula (i believe) is:
A = 2r[tex]\pi[/tex]
A = 2(3)(3.14)
A = (6)(3.14)
A = 18.84

Step-by-step explanation:
We know that the circles diameter is 15 mm. We can tell that by looking at the side of the rectangle. It says 15 mm.
Either way, we use the formula to find the area of a circle:
A = [tex]\pi[/tex]d
A = (3.14)(15)
A = 47.1
The area of the circle is 47.1. (i think?)
sowwy if it took long
Answer:
426.45 mm
Step-by-step explanation:
find the area of the circle by multiplying the radius by pi(3.14) then you would subtract that from the area of the rectangle. Hope this helps

Sofia's family took a road trip to Mount Rushmore. Sofia slept through the last 65% of the trip. If the total length of the trip was 840 miles, how many miles had they travelled when Sofia fell asleep?
Answer:
546
Step-by-step explanation:
Sofia slept 546 miles and was awake for 45% which is 294 of the miles.
You can find this by finding 1%, and that would be 8.4. (You get 1% from dividing 100 from the 100% number.) Then you multiply it by 65 so now you get 546.
If the total length of the trip was 840 miles, then Sofia had traveled 294 miles before she fell asleep.
Given that,
If Sofia slept through the last 65% of the trip and the total length of the trip was 840 miles,
then she stayed awake for the first 100% - 65% = 35% of the trip.
Here, we have to calculate the distance she traveled before falling asleep, we can use the percentage of the total distance:
Distance traveled by Sofia = 35% of 840 miles
Distance traveled by Sofia = 0.35 * 840
Distance traveled by Sofia = 294 miles
So, Sofia had traveled 294 miles before she fell asleep.

Answer:
Im pretty sure its C... Step-by-step explanation: what im seeing here is 10 with the small numbers in front so it looks like scientific notation, Maria has 1 million because 1 x a number = that number, 10 multiplied by itself 6 times equals 1 million, 10 x10 = 100 x 10 = 1000 x 10 = 10,000 x 10 = 100,000 x 10 = 1,000,000. so from this we know what Larry's 10 to the power of 5 is, we need to know what 100,000 x whatever equals. If im doing this right, Larry's number is 1 million 2 hundred thousand which is greater than 1 million. (sorry if the explanation is wanky and sorry if it was wrong, im new to brainly.)
