Make v the subject
KE=1/2 mv^2
The solution of the equation for v is [tex]v = \sqrt{\frac{2KE}{m}}[/tex]
What is subject of formula?This involves isolating a variable in an equation different from the initial isolated variable
How to determine the equation for v?The equation is given as
KE = 1/2mv²
Divide both sides of the equation by m
So, we have the following equation
KE/m = 1/2mv²/m
Multiply both sides of the equation by 2
So, we have the following equation
2KE/m = 2 * 1/2mv²/m
Evaluate the quotients and the products
2KE/m = v²
Take the square roots
[tex]v = \sqrt{\frac{2KE}{m}}[/tex]
By the above computation, we changed the subject of the formula in KE = 1/2mv² from KE to v.
This implies that solving for v is a concept of subject of formula
Hence, the solution is [tex]v = \sqrt{\frac{2KE}{m}}[/tex]

The angle of elevation of the sun during a certain time of day is 42.4°. At this specific time day a 32.5 foot tree casts a shadow on the ground. How long is the tree's shadow?
The length of the tree's shadow will be 35.59 ft.
What is tangent function? Also explain how it is used in heights and distances?
Tangent function is one of the six trigonometric functions in mathematics. In heights and distances, tangent of the angle of elevation or depression can be used to calculate the distance or height of an object as -
tanФ = [P]/[B]
The domain and range of the tangent function is -
Domain - R - {(2k+1)π/2} [where k is an integer]
Range - R [where R is the set of real numbers]
Given is angle of elevation of the sun during a certain time of day as 42.4°. At this specific time day a 32.5 foot tree casts a shadow on the ground.
Assume that angle of elevation is equal to Ф
Now, using the tangent function, we can write -
tanФ = [tree height] / [tree shadow]
tan(42.4) = 32.5 / [tree shadow]
tree shadow = (32.5/tan(42.4))
tree shadow = 32.5/0.913 = 35.59 ft
Therefore, the length of the tree's shadow will be 35.59 ft.

Which ordered pair is the best estimate for the solution to the system?
The ordered pair that is the best estimate for the solution to the system is (1/2,0).
Ordered pair:
An ordered pair is the composition of the x coordinate and the y coordinate , having two values written in a fixed order within parentheses.
Given,
Here we have the graph.
And we need to find the the best estimate for the solution to the system.
While we looking into the graph we have identified, that both line will intersect at some point.
Basically the solution of the graph is also the same point.
So, when we look into the graph we have identified that the value of y at the intersecting point is 0. Because the line will pass the x - axis line.
So, here we have to identify the x value of the solution,
this one the value of x is greater than or equal to 0.5. Because the line will be pass in between 0 and 1.
Considering all these details, the solution pair is (1/2 ,0).

-1/2 is the slope of the line that passes through the points (12,-1) and (-2,6).
Slope is simply expressed as change in y over the change in x.
The slope formula is expressed as;
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Given the data in the question;
Point 1( 12, -1 )
x₁ = 12y₁ = -1Point 2( -2, 6 )
x₂ = -2y₂ = 6To determine the slope of the line, plug the given coordinates into the slope formula above.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 6 - (-1) )/( -2 - 12 )
Slope m = ( 6 + 1) )/( -2 - 12 )
Slope m = ( 7 ) )/( -14)
Slope m = -7/14
Slope m = -1/2

vertex (-5,3) and passes through (-4,2)
The equation of the parabola that has a vertex at (-5,3) and passes through (-4,2) is y = [tex]-x^2-10x-22[/tex]
The vertex of the parabola = (-5,3)
Passing through the point = (-4,2)
The equation of the parabola in the vertex form y = [tex]a(x-h)^2+k[/tex]
(h,k) is the vertex of the parabola
h = -5
k = 3
Substitute the values in the equation
y = [tex]a(x+5)^2+3[/tex]
Here the parabola is passing through the point (-4,2)
Substitute this value in the equation and find the value of a
2 = [tex]a(-4+5)^2+3[/tex]
2 = a×1+3
2 = a+3
a = 2-3
a = -1
Then
y = [tex]-1(x+5)^2+3[/tex]
y = [tex]-1(x^2+10x+25)+3[/tex]
y = [tex]-x^2-10x-25+3[/tex]
y = [tex]-x^2-10x-22[/tex]
Hence, the equation of the parabola that has a vertex at (-5,3) and passes through (-4,2) is y = [tex]-x^2-10x-22[/tex]

one tenth
negative one tenth
negative one fourth
Answer:
0.7
Step-by-step explanation:
This question tests on the concept of slope or gradient of a line.
We know that the equation, m, for a slope =
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
We can identify 2 points from the question as (x1, y1) and (x2, y2) to solve for the gradient, and therefore they are:
(x1,y1) as (-3,-7.5)
(x2,y2) as (2,-4)
Now we can substitute these values in to solve for the slope.
[tex] \frac{ - 4 - ( - \frac{7}{2})}{2-(-3)} \\ = \frac{ - 4 + frac{7}{2}}{5} \\ = \frac{-0.5}{5} \\ = - \frac{1}{ 10} \\ = -0.1[/tex]

A general exponential model can be described by:
[tex]P(x)=A\cdot b^x[/tex]Where A is the initial condition, and b is the growth factor. From the problem, P is the population (in millions); if x is the number of years passed since 2011, then x = 0 in 2011:
[tex]105=A\cdot b^0\Rightarrow A=105[/tex]We know that the growth rate is -0.657% = -0.00657. The growth rate r and the growth factor b are related by:
[tex]b=1+r\Rightarrow b=1+0.00657=0.99343[/tex]Our model is now complete:
[tex]P(x)=105\cdot0.99343^x[/tex]For the year 2024, x = 13 years have passed. Then, we calculate the population using our model (rounding to the nearest hundredth):

The gravity is working. Energy-based items are affected by gravity. The vertical motion model, h = -16t2 + vt + s, where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball.
Why is initial height important?The distance traveled in flight increases with release level. This is because the projectile will stay in the air longer if it is launched higher. The projectile will be under the influence of the horizontal component longer.
The beginning vertical velocity determines the maximum height. Increasing the launch angle raises the maximum height because steeper launch angles have a larger vertical velocity component.
Greater maximum height is associated with greater launch angles.
Greater relative projection height results in longer flight time, which increases horizontal displacement when projection speed is constant.

The given scales which measure the attitude of a person is an ordinal scale such as a Likert scale
What is an ordinal scale?An ordinal scale provides a report of the rating, order or rank of a data without stating the extent of variation between the categories.
There are many types of rating scales used to directly measure the attitude of a person towards a subject matter.
The Likert scale which is the most widely used rating scale, when applied, consists of a five or seven point scale, that empowers the subject of the survey to express how much they agree (or disagree) with a specified statement.
Generally, five options, graded from, mild to extreme are provided so that the survey subject can indicate (express), their strength of how much they agree with or feel about the statement or question
The assumptions of the Likert scale includes;
The ability to measure attitudes.The intensity or strength of an attitude is linear, such that the attitude varies linearly from strongly agree to strongly disagreeBased on the perception of the subject, Likert scale can be used to also measure the variations of the following subject matters;
