Answer:
She walks 100 m in 1 minute
Step-by-step explanation:
Here, given the equation, we want to know the distance covered in a minute
From the question, the equation is;
d = 100t
so when t is 1
d = 100 * 1 = 100 m
Answer:
200 m s^-2.
133.33 ms^-2.
100 m s^-2.
Step-by-step explanation:
Use Newton's Second Law of motion:
Force = mass * acceleration
The force is in Newtons so the mass must be in kilograms#
100 g = 0.1 kg. So:
20 = 0.1 * a
a = 20/ 0.1 = 200 m s^-2.
We calculate the acceleration for the 150g and 200g potato in the same way.
The discriminant is part of the quadratic formula which is b²-4ac.
So, in this case,
b²-4ac = (-9)(-9) - 4(7)(-8) = 305
To clarify the systems of equations:


We already have opposite coefficients for y, so combine the two equations together:

Divide both sides by 5 to get x by itself:

Because we now know x, we can plug it into one of the equations.
We will plug this value into the first equation:


Add 24 to both sides.

Divide both sides by -1 to get y by itself.

Using elimination,
x = 2 and y = -30.
Answer:
f(x) = 8 - 1.5x
Step-by-step explanation:
Here, we want to write a function that can be used to describe the x th term of the sequence
Mathematically, this can be calculated by looking at the numbers in the sequence
The difference between each successive term
is -1.5 ( 6.5-8, 3.5 -5)
So the formula for then x th term will be;
f(x) = 8 - 1.5x
where x refers to the number of the term , for example the 4th term
