a ball is dropped from rest from a high window of a tall building and falls for 4 seconds. Neglecting air resistance. The final velocity of the ball is m/s. (g=-9.8m/s 2) the first person to answer me gets the brainliest
Step-by-step explanation:
v=u+at
v=0+9.8m/s2 ×4s
v=39.2 ms-1
Final velocity; v = -39.24 m/s
In free fall, the motion is in the direction of gravity.
Formula for final velocity in free fall is;
v = u + gt
(g is negative)
We are told the ball is dropped from rest.
Thus;
Initial velocity: u = 0 m/s
Time; t = 4 secs
Acceleration due to gravity; g = -9.81 m/s²
Thus, Plugging in the relevant values, we have;
v = 0 + (-9.81 × 4)
v = -39.24 m/s
Final velocity; v = -39.24 m/s

f(x) = ((x^2) / 3) + x, for f(6)
f(6) = ((6^2) / 3) + 6
Square 6
f(6) = (36 / 3) + 6

Triangle DEF is a right triangle. What is the measure of ZEFD?
D
57°
F
E
Answer:
33°Step-by-step explanation:
Sum of measures of angles in any triangle is 180°
The maesure of right angle is 90°
So: m∠EFD = 180° - 90° - 57° = 33°
if x=2⅓-2, then find the value of x³+6x²+12x
Answer:
-6
Step-by-step explanation:
In this equation it gives us the value of x which is,
×=2^(1/3)-2
x=-.74
We then need to plug in this value to, x³+6x²+12x
(-.74)³+6(-.74²)+12(-.74)

The quotient of the three times a number and the quantity 4 plus the same number. Use n.
if the quotient of three times a number and four is decreased by three, the result is nine. whats the number
Answer :Trevor,
number = x
(3x÷ 4) - 3 = 9
Use a common denominator 4: 3x - 12 = 36
3x = 48
x = 16
Does it fit the original equation?
[(3 x 16) ÷ 4] -3 = (48 ÷ 4) -3 = 12 - 3 = 9

Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the
towns can be represented by four points: A, G, M, and W. Given that M is the midpoint of AW and MG =
MA + GA, determine the
proper order of the four towns.
Answer:
W, M, A and G
Step-by-step explanation:
The question is not correct, the correct question is Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the towns can be represented by four points: A, G, M, and W. Given that MG + WM = WG and MA = MG - AG determine the proper order of the four towns.
Answer: The line segment addition postulate states that for a line segment AC with point B which lines on AC, then this equation holds:
AB + BC = BC
Given that MG + WM = WG, this means that point M lies between the segment WG.
Also, MA = MG - AG
MA + AG = MG, hence point A lies between segment MG
Therefore the order of the points is W, M, A and G

Answer:
[tex]\boxed{\tt A. \angle8 \ and \angle 7}[/tex]
Step-by-step explanation:
Supplementary angles are angles that add to 180 degrees.
Let's examine the answer choices.
A. ∠8 and ∠7
⇒ These angles are on a straight line together, so they are supplementary.
B. ∠5 and ∠1
⇒ These angles have no relation to each other. They are on different lines that are not parallel.
C. ∠7 and ∠4
⇒These angles also have no relation to each other.
D. ∠2 and ∠4
⇒ These angles are vertical, but not supplementary.
The correct answer is A. ∠8 and ∠7

A rectangular pan has a length that is the width. The total area of the pan is 432 in.2. What is the width of the cake pan? A = lw 10.4 in. 13.9 in. 18 in. 24 in.
Answer:
Let width = w
length = 4w/3
Area = 432 = length*width = w*4w/3
4w^2/3 = 432
w^2 = 432*3/4 = 324
w = 18
so the width of the cake pan is 18 inches.
The width of the rectangular pan is 18 inches and this can be determined by using the formula of the area of the rectangle.
Given :
A rectangular pan has a length that is 4/3 the width.
The total area of the pan is 432 square inches.
The following steps can be used in order to determine the width of the cake pan:
Step 1 - The formula of the area of the rectangle can be used in order to determine the width of the cake pan.
Step 2 - The area of a rectangle is given below:
[tex]\rm A = LW[/tex]
where L is the length and W is the width of the rectangle.
Step 3 - According to the given data, the length is 4/3 the width.
Step 4 - Substitute the values of the known terms in the above expression.
[tex]\rm 432 = w\times \dfrac{4w}{3}[/tex]
Step 5 - Simplify the above expression.
[tex]\rm 432 = \dfrac{4w^2}{3}[/tex]
[tex]\rm w^2 = 324[/tex]
w = 18 inches
