To find the acceleration we divide the change of velocity by the change of time.
Change of velocity: 4 m/s
Change of time: 2 s
Acceleration =

So the answer: his acceleration is
2 m/s^2
Answer:
Length of the hypotenuse = 8.5 units
Step-by-step explanation:
Given the length of the sides of an isosceles right triangle to be 6units
Hint: an hypotenuse is the longest line
To solve this, we use Pythagoras rule
Hypotenuse^2 = adjacent ^2 + opposite ^2
Adjacent = opposite = 6
Let our hypotenuse to be a
a^2 = 6^2 + 6^2
a^2 = 36 +36
a^2 = 72
To get a, let's find the square root of 72
a = 8.485 unit
Therefore, the length of the hypotenuse = 8.5 units

Answer:X= 1.84. Y= 3.08
Step-by-step explanation:
-9x+8y =8 ............i
-8x+10y= -16........ii
Multiply equation I by 8
Multiply equation ii by 9
-72x+64y = 64 ..... iii
-72x+90y = 144 ..... iv
Subtract iv from iii
-26y = -80
y= 80/26
y= 3.08
Put the value of y in equation i
-9x+8y =8
-9x+8(3.08) = 8
-9x+24.64 = 8
-9x = 8-24.64
-9x=-16.64
Divide both side by 9
-9x/-9 = -16.64/-9
X= 1.84
Answer:
4
Step-by-step explanation:
The plus and minus sign cancel each other out so it becomes 7-3=4
