The acceleration of the object will be 10 m/s²
Step-by-step explanation:
Direct variation is a relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
- If y varies directly with x, then y ∝ x
- y = k x, where k is the constant of variation
For a moving object, the force acting on the object varies directly with the object's acceleration.
Assume that the force is F and the acceleration is a
∵ F ∝ a
∴ F = k a
∵ F = 20 newtons
∵ a = 4 m/s²
- Substitute these values in the equation above to find k
∵ 20 = k (4)
∴ 20 = 4 k
- Divide both sides by 4
∴ k = 5
- Substitute the value of k in the equation
∴ F = 5 a ⇒ equation of variation
∵ F = 50 Newtons
∵ F = 5 a
∴ 50 = 5 a
- Divide both sides by 5
∴ 10 = a
∴ a = 10 m/s²
The acceleration of the object will be 10 m/s²

The slope is 2 i’m pretty sure
<span>Michael bought 0.44 pound of sliced turkey.
Now, we need to find what digit is in the value of hundredths.
Note, that the place value is hundredths with ths. Thus, the value is in the
decimal points.
And the value that Michael bought is a decimal number as well.
Not, let us find the value of hundredths.
=> 0.44 pounds
=> .4 = tenths
=> 0.04 = hundredths.
Thus the value of hundredths is 4 or 0.04 or 4/100 in fraction form.

8x^2+14x=0
Take 2x as a common factor:
2x(4x+7)=0
Take 2 cases:
2x=0 or 4x+7=0
2x=0 x=0
4x+7=0 4x=-7 x=-7/4
The roots are 0 or -7/4.
Hope this helps :)
Answer:
1. x =-4 (-4,27)
x =0 (0,3)
x = 2 (2 , -9)
2. x = -1 (-1 , 3)
x = -2 (-2 , 2)
x = -3 ( -3, 1)
3. x = -3 (-3 , 13)
x = 1 (1 , 1)
x = -2 ( -2, 10)
4. x =2 (2 , 24)
x = 3 (3 , 30)
x = -2 (-2 , 0)
5.x = -3 (-3 , -2)
x = 2 (2 ,-12 )
x =4 (4 , -16)
6. x = -1 (-1 , -2)
x = 0 (0 , 2)
x = 2 (2 , 10)
7. x = -2 (-2 , -10)
x = 0 (0 , -14)
x = 3 (3 , -20)
