object is 10 m/s. If the force is changed to 90 N, what will be the acceleration of the object?
Answer:
acceleration would be 9 meters per second squared
Step-by-step explanation:
If quantity "A" varies directly with quantity "B", then we can write:
A = kB
Now, this problem says that force (f) varies directly with acceleration (a). So we can write:
f = ka
Given f = 100 and a = 10, so we substitute and find k (the proportionality constant). Shown below:
f = ka
100 = k(10)
k = 100/10
k = 10
So, we have
f = 10a
Now, force is 90, so what's the acceleration?
90 = 10a
a = 90/10
a = 9
So, the acceleration would be 9 meters per second squared
Answer:
11
Step-by-step explanation:
7 + (2 + 6) 2 ÷ 4
Using BODMAS in order of solving, which stands for (bracket,of,division,multiplication,addition,subtraction)
This means we take bracket first
(2+6) = 8
So we have now, 7 + 8 ×2 ÷ 4
Division is next = 2÷4 = 1/2
So we have
7 + 8 × 1/2
Now multiplication
8 × 1/2 = 4
Now we have,
7 + 4
= 11

Answer:
Step-by-step explanation:
The equation of a vertical line through an ordered pair is given by:
The given ordered pair is (-6,-1).
The x-value of this ordered pair is -6.
Therefore the equation of the line that is a vertical line that passes through(-6, -1) is
What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?
A.y = −4x − 4
B.y = −4x − 6
C.y = x – 4
D.y = x – 6
Step 1
Find the slope of the given line
Let
we know that
The formula to calculate the slope between two points is equal to
substitute the values
Step 2
Find the slope of the perpendicular bisector
we know that
If two lines are perpendicular, then the product of their slopes is equal to minus one
so
In this problem
