The age of a man whose normal blood pressure measures 123 mm of hg
9 years
<h3>What is Quadratic equation ?</h3>
A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic equation is y = a
+ bx + c, where a, b, and c are numbers and a cannot be 0
P(A) = 0.006 
- 0.02a + 120
123 = 0.006- 0.02a + 120
0=0.006 - 0.02a - 3
you can use the quadratic equation formula to solve for the man's age.
A = (-b ± (
) ) / (2a)
A = (0.02 ± 
/ (2*0.006)
A = (0.02 ± 
) / 0.012
A = 9 , -5.67
Age of the man will be 9 years

Answer:
How long will it take to travel a distance of 96 km? Givens. Solving For ... An object accelerates 3.0 m/s2 when a force of 6.0 Newtons is applied to it.
Explanation:
Answer:
Following are the solution to the given points:
Explanation:
For point a:
Find the schematic of the empty body and in attachment. Upon on ball during the pitch only two forces act:
The strength of the pitcher F is applied that operates horizontally. Its gravity force acting on an object is termed weight, which value is where m denotes mass, and g the acceleration of gravity.
For point b:
First, they must find that ball's acceleration. You can use the SUVAT equation to achieve that
where
Solving for a,
Calculating the mass:
Calculating the force:
For point c:
0.195 times the pitcher's weight
Solving for W:
Now the force of Part B could be defined as the fraction of the mass of the pitcher:
The force that control the isostatic adjustment of the earth's crust is THE FORCE OF GRAVITY.
The isostatic adjustment of the earth crust refers to continuous movement of the earth crust or its deformation as a result of the force of gravity which act on it. The earth crusts that are located at the upper and a the core of the earth usually set up a balance between them which is called isostatic equilibrium.
Answer:
acceleration 8 km/h/s south
Explanation:
First of all, let's remind that a vector quantity is a quantity which has both a magnitude and a direction.
Based on this definition, we can already rule out the following two choices:
distance: 40 km
speed: 40 km/h
Since they only have magnitude, they are not vectors.
Then, the following option:
velocity: 5 km/h north
is wrong, because the car is moving south, not north.
So, the correct choice is
acceleration 8 km/h/s south
In fact, the acceleration can be calculated as
where
v = 40 km/h is the final velocity
u = 0 is the initial velocity
t = 5 s is the time
Substituting,
And since the sign is positive, the direction is the same as the velocity (south).
