A) make U subject of the formula E= m/2g(v^2-u^2)
Answer:
u = v2−2Egm−−−−−−−√
Step-by-step explanation:
2Eg = 2g (M2g(V2−U2)
2Eg = m(V2 - U2)
2Eg - mV2 - mU2
mU2 = mV2 - 2Eg
mU2m=mV2−2Egm
U2 = mV2−2Egm
= mV2m−2Egm
U2 = V2 - 2Egm
U = V2−2Egm−−−−−−−−√

QUESTION 2:
The area of the polygon is 21.5 units²
QUESTION 3:
The area of the combined figure is 12 + 18.25·π units²
QUESTION 4:
The area of the figure is 40 units²
QUESTION 5
The area of the compost shape is 40 in.²
Step-by-step explanation:
QUESTION 2.
The area of the polygon is given as follows;
The area of two triangles + The area of trapezoid
1/2×6×3 + 1/2×3×4 + 1/2×(6 + 7) = 21.5 units²
QUESTION 3
The diameter of the semicircle, 'd', is given as follows;
d = √(8² + 3²) = √73
The area of the semicircle = π·d²/4 = π·73/4 = 18.25·π unit²
The area of the right triangle beside the semicircle is given as follows;
1/2 × 8 × 3 = 12 unit²
The area of the combined figure = The area of the semicircle + The area of the right triangle
∴ The area of the combined figure = 12 + 18.25·π units²
QUESTION 4:
The dimensions of the parallelogram are;
Width, W = √(4² + 1²) = √(17)
Length, L = √(8² + 2²) = √(68)
The area of the parallelogram, [tex]A_R[/tex] = W × L = √(17) × √(68) = √(17 × 68) = 34
The area of the parallelogram, [tex]A_R[/tex] = 34 units²
The length of a parallel side, 'A', of the parallelogram is A = 6
The height of the parallelogram, is h = 1
The area of the parallelogram is A = B·h = 6 × 1 = 6 units²
The area of the figure is the sum of the area of the rectangle and the area of the parallelogram
Therefore, we have;
The area of the figure = 34 units² + 6 units² = 40 units²
QUESTION 5
The composite shape consists of a triangle and a rectangle
Therefore, we have;
The area of the rectangle = 5 in. × 7 in. = 35 in.²
The area of the triangle = 1/2 × 2 in. × 5 in. = 5 in.²
The area of the compost shape = The area of the rectangle + The area of the triangle
∴ The area of the compost shape = 35 in.² + 5 in.² = 40 in.²
The area of the compost shape = 40 in.².

Answer: Hence, the coordinates of F =(2,11)
Step-by-step explanation:
Translation rule to move a figure with coordinates (x,y) by h units left and k units left:
[tex](x,y)\to (x-4,y+3)[/tex]
Coordinates of F = (6,8).
After translation of 4 units left and 3 units up, the coordinates of F = [tex](6-4,\ 8+3)=(2,\ 11)[/tex]
Hence, the coordinates of F =(2,11)

I recommend using math w ay algebra problem solver to get answer on the first question.
Answer:
1) slope = 3
y-intercept = -1
2) linear
non-linear
Step-by-step explanation:
In the equation y=mx+b, m is the slope and b is the y-intercept. The number next to the x will always be the slope, and the number after represents the y-intercept.
Linear graphs are always straight lines, the values are always constant.
Non-linear graphs are graphs with curves.

Step-by-step explanation:
A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or F = $2.25 + $0.20(m - 1) where F is the fare and m is the number of miles.
if juan's taxi fare was $7.65 how many miles did he traavel in the taxi
Answer: Juan travelled 28 miles in the taxi
Step-by-step explanation:
A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile. This means that for m additional miles, the charge will be 2.25 + 0.20(m - 1)
So if F represents the fare, then
F = $2.25 + $0.20(m - 1)
If Juan's taxi fare was $7.65, to determine the number of miles that she paid for, we would substitute F = $7.65 into the equation,
F = $2.25 + $0.20(m - 1). It becomes
7.65 = 2.25 + 0.20(m-1)
7.65 = 2.25 + 0.20m - 0.20
7.65 - 2.25 + 0.20 = 0.2m
0.2m = 5.6
m = 5.6/0.2 = 28 miles
Answer:
Juan traveled 28 miles in the taxi
Step-by-step explanation:
7.65=2.25+0.2(m-1), subtract 2.25 from both sides, then you get 5.40=0.2(m-1)
then multiply 0.2 by the numbers in the parenthesis and get 5.40= 0.2m-0.2
add 0.2 to both sides to get 5.60 = 0.2m, divide both numbers by 0.2 and get 28 = m

Step 1- Find the sum of degrees in the polygon using the equation below. n=number of sides in the polygon
(n-2)180
(8-2)180=6(180)= 1080
Step 2-Subtract the angles provided to find x
1080-129-132-136-124-141-158-116=144
The value of x in the octagon is given by the equation x = 144°
What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180° ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the number of sides of the polygon be represented as n
The value of n = 8
So , the sum of the interior angles of an octagon is given by
nθ = 180° ( n - 2 )
Substituting the values in the equation , we get
nθ = 180° ( 8 - 2 )
nθ = 180° x 6
nθ = 1080°
Now , the angles in the octagon = { x , 124° , 141° , 158° , 116° , 129° , 132° , 136° }
Sum of the interior angles of an octagon A = 1080°
Substituting the values in the equation , we get
x + 124° + 141° + 158° + 116° + 129° + 132° + 136° = 1080°
x + 936° = 1080°
x = 144°
Therefore , the value of x is 144°
Hence , the value of x from the polygon is 147°

The expression 16t power 2 represents the distance in feet an object falls after t second a. Write an expression representing the height of the object t seconds after it is dropped b. What is the height of subject 3 seconds after this dropped
Answer:
[tex]H(t) = 16t^2[/tex]
Height 3 seconds after is 144ft
Step-by-step explanation:
Given
Expression: 16t power 2
Solving (a): Write as an algebraic expression.
Let H represent the height after t seconds.
So, we have:
[tex]H(t) = 16t^2[/tex]
Solving (b): The height after 3 seconds
This implies that:
[tex]t = 3[/tex]
Substitute 3 for t in [tex]H(t) = 16t^2[/tex]
[tex]H(3) = 16 * 3^2[/tex]
[tex]H(3) = 16 * 9[/tex]
[tex]H(3) = 144[/tex]
Hence, the height is 144ft
