Answer:
Weight of the truck=9408 N
Step-by-step explanation:
Boat is experiencing the buoyant force as it is in the water and is sinking
According to the force balance in y direction. As both is floating, two forces balance each other:
where:
is the buoyant force
is the weight=mg
Eq (1)
Buoyant force is equal to the mass of water displaced * gravitational acceleration.
Taking density of water to be 1000 Kg/m^3
From Eq(1):
Weight of the truck=9408 N
Answer:
1. new perimeter = 4 times the old perimeter
2. The area will go up by a factor of 16
3. The new area is 1/9 of the original area.
Step-by-step explanation:
1. side length1 = x
side length2 = y
2x + 2y = perimeter
2(4x) + 2(4)y = new perimeter
8x + 8y = new perimeter
new perimeter = 4 times the old perimeter
2. The area will go up by a factor of 16. This is because the area formula has them being multiplied together and thus it will make the area go up by that much.
3. Let the length of the rectangle be x
Let width of rectangle be y
Area of rectangle = L*W
Now Each side length of the rectangle is multiplied by 1/3
So, new area = (1/3)L * (1/3)W
=(1/9)LW
So, the new area is 1/9 of the original area.
Rational roots theorem states that any rational root will be a factor of the constant over a factor of the leading coefficient.
The given equation is: <span>f(x) = 3x^4 + x^3 - 13x^2 - 2x + 9. </span>In this case, it is a factor of 9 over a factor of 3.
<span>Factors of 9: ±1, ±3, ±9 </span>
<span>Factors of 3: ±1, ±3 </span>
So possible rational roots are: ±1, ±3, ±9, ±1/3
