Answer:
The easiest way to determine whose offense or defense would be to check where the players are positioned at. Obviously, the main goals of Soccer or Football are in the back meaning people who are defending the goal are most likely to be behind the teammates who are offensive (common sense).

An equation for a toy boat is bobbing on the water is in the sinusoidal form which we can write as, D(t) = 0.2 sin2t +1
What is an Equation ?
An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.
For example, D(t) = acos2t +b
Types of equation
1. Linear Equation
2. Quadratic Equation
3. Cubic Equation
Given information,
Equation of bobbing, D(t) = a sinbt + d
By graph we can say that it is compressed two times,
So, value of b will be, 2
At t =0, height from the floor is 1 m
1 = a sin(2×0) + d
d = 0
At t =π/4, height from the floor is 1.2 m
1.2 = a sin(2×π/4) + 1
a = 0.2
By graph we can say that it is compressed two times,
So, value of b will be 2
Hence, An equation is D(t) = 0.2 sin2t +1

I WILL GIVE BRAINIEST!!!! Help!!!! 4. A stone nudged off the Royal Gorge Bridge near Cañon City, Colorado, falls 1053 feet before
hitting water. Because its speed increases as it falls, the distance it travels each second
increases. During the first second, it drops 16 feet. During the next second, it drops an
additional 48 feet. During the third second, it drops another 80 feet. The distances traveled
each second form an arithmetic sequence:
16, 48, 80, ...
Part I: How far does the stone fall during the 5th second? Find and use the explicit formula.
a. What is the first term of the sequence?
b. What is d, the common difference?
c. Write the explicit formula in function notation. Use f(n) = f(1) + (n - 1)d, where f(1)
Answer:
First term = a= 16.
Common difference, d, = 32.
Answer for the fifth second is = 144 feet.
Step-by-step explanation:
This question is simply an Arithmetic Progression, AP,.
so, the 1st second represents the first term and so on.
for the common difference, you just subtract the first from the second term and confirm by subtracting the second from the third term and i got 32.
Let R be the region in the first quadrant bounded above by the graph of y=1−x^2 and below by the graph of y=1−√x, as shown in the figure above. What is the area of the region?
If R be the region in the first quadrant bounded above by the graph of y=1−x² and below by the graph of y=1−√x then area is 1/3.
To find the area of the region bounded by the graphs of y = 1 - x² and y = 1 - √x in the first quadrant.
we need to determine the points of intersection and integrate the difference between the two functions over that interval.
To find the points of intersection, we set the two functions equal to each other:
1 - x²= 1 - √x
x²= √x
Squaring both sides again, we have:
x⁴ = x
x(x³ - 1) = 0
This equation gives us two potential solutions: x = 0 and x = 1.
To determine the limits of integration, we need to find the x-value where the two curves intersect.
Since y = 1 - √x represents the upper curve, we can set the two functions equal to each other and solve for x:
1 - x² = 1 - √x
x² = √x
x⁴ = x
Since we are only interested in the first quadrant, the solution x = 0 is not relevant.
Therefore, the only point of intersection is x = 1.
Integrating the difference between the two functions over the interval [0, 1] will give us the area of the region R:
A = ∫[0, 1] (1 - x²) - (1 - √x) dx
Expanding and simplifying the integrand:
A = ∫[0, 1] 1 - x² - 1 + √x dx
A = ∫[0, 1] -x² + √x dx
Integrating each term separately:
A = [-x³/3 + (2/3)x^(3/2)]|[0, 1]
A = [-(1/3) + (2/3)] - [0]
A = 1/3
Therefore, the area of the region R is 1/3.

We should go 4 units up from the zero in the coordinate plane.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
Given that, in the ordered pair (3, 4), the value of y is 4.
Here, in the ordered pair (3, 4), 3 is x-coordinate and 4 is y-coordinate.
The perpendicular distance from the x-coordinate 3 and y-axis is 3 units, which is 3 units right to the y-axis.
The perpendicular distance from the y-coordinate 4 and x-axis is 4 units, which is 4 units up to the x-axis.
Hence, we should go 4 units up from the zero in the coordinate plane.

Two boys san around a track that is 400 meters long. Miguel ran around the track three
times in 240 seconds. Joseph ran around the track three times in 200 seconds. What was the
difference between the speeds of the two boys?
A.
1 meter per second
5 meters per second
B.
C.
6 meters per second
D.
11 meters per second
Using proportions, it is found that the difference between the speeds of the two boys was of:
A. 1 meter per second.
What is a proportion?A proportion is a fraction of a total amount. Following this concept, velocity is distance divided by time.
In this problem, Miguel ran 1 lap = 400 meters each 240/3 = 80 seconds, hence his speed is given by:
sM = 400/80 = 5 m/s.
Joseph ran 400 metters each 200/3 = 66.67 seconds, hence his speed is given by:
sJ = 400/66.67 = 6 m/s.
The difference is given by:
6 m/s - 5 m/s = 1m/s.
Hence, option A is correct.
